This qualitative secondary analysis reanalyzes data from a Q methodology study with 66 participants from a variety of library types in Slovenia, South Africa, and the United States. In the original Q methodology study, many participants ranked the statement "librarian as agent of change" as an important conceptualization of reference and information service (RIS). To elucidate and expand this finding, the qualitative data surrounding "librarian as agent of change" were analyzed thematically to understand how participants viewed, or did not view, RIS as making change. Results show that for librarians who perceive themselves as agents of change, making change is an obligation that librarians are particularly suited to do. In addition, change can be viewed on different levels—individual, organizational, and societal. Results show that the pervasiveness of neutrality in RIS prevents some librarians from taking on a role supporting social change and advocacy. [ABSTRACT FROM AUTHOR]

This study explores the representation of scientists and politicians in editorial cartoons from three countries: Australia, South Africa and the United Kingdom. Of 466 cartoons collected from six Sunday newspapers (two from each country) over an 18-month period, 226 (49%) contained some reference to COVID-19. A qualitative analysis of cartoons highlights the politicisation of science and the relative absence of scientists in the cartoon discourse. Cartoonists focus on the political aspects of the pandemic, often portraying politicians as juggling competing demands, such as health needs versus personal freedom. However, they often miss the opportunity to address the reasons for the imposition of COVID-19-related restrictions or the effectiveness of health measures, instead portraying scientists as oppositional figures. In addressing COVID-19 in this way, cartoonists subtly suggest conflicts between the values of scientists, politicians and society. Cartoonists also tie the pandemic into broader political discourses in each country, for example, states' rights, corruption and Brexit in, respectively Australia, South Africa and the UK. This work provides insights into journalistic coverage of complex, science-related issues, with a particular focus on the ways that editorial coverage reflects public sentiment, policy responses and social attitudes.

Micro language planning is often framed as democratic, transformative, inclusive, and therefore, less contested as it reproduces community consensus and support. This is contrasted with macro or top-down language planning which is power inflected and weaponised to serve interests of the dominant class. Through a theorisation of institutional language policies as products of micro language planning, this article analyses the language policy of one university in South Africa and reveals that, contrary to this widely held view, bottom-up language planning is also a site of struggle and contestation. In particular, we focus on specific language policy provisions that reveal the university’s underlying disposition towards multilingualism and linguistic identities. The analysis reveals multi-layered contestations on multilingualism and identity inherent in the university’s language policy. While the language policy purports to foster transformation by promoting multilingualism through the university’s ‘languages of choice,’ it is not exempt from the vagaries of essentialist identity politics and macro level language ideologies which legitimise English and Afrikaans. By identifying only four languages for promotion, the language policy envisages a kind of ‘exclusionary multilingualism’ that disregards the cosmopolitan character of the university and the identities marked by indigenous African languages left invisibilised by the language policy.

We assessed the impact of community- versus clinic-based medication pick-up on rates of virologic suppression in an observational cohort of adults on ART enrolled in a decentralized antiretroviral therapy program (CCMDD) in South Africa. Participants either attended clinics where they were given the choice to pick up ART in community venues or traditional clinics, or clinics where this pathway was assigned. Among 1856 participants, 977 (53%) opted for community ART pick-up at enrollment, and 1201 (86%) were virologically suppressed at one year. Because of missing data on virologic suppression, primary results are based on a model incorporating multiple imputation. In addition to age and gender, distance from clinic and year of HIV diagnosis were included in the multivariable model. There was no difference in opting for clinic- vs. community-based pick-up with regard to achieving 12-month virologic suppression (aRR 1.02, 95% CI 0.98–1.05) in clinics offering choice. There was no impact of assigning all participants to an external pick-up point (aRR 1.00, 95% CI 0.95–1.06), but virologic suppression was reduced in the clinic that assigned participants to clinic pick-up (aRR 0.87, 95% CI 0.81–0.92). These results suggest that provision of community-based ART has not reduced continued virologic suppression in the population enrolled in the CCMDD program. [ABSTRACT FROM AUTHOR]

Desiccation tolerance evolved recurrently across diverse plant lineages to enable survival in water-limited conditions. Many resurrection plants are polyploid, and several groups have hypothesized that polyploidy contributed to the evolution of desiccation tolerance. However, due to the vast phylogenetic distance between resurrection plant lineages, the rarity of desiccation tolerance, and the prevalence of polyploidy in plants, this hypothesis has been difficult to test. Here, we surveyed natural variation in morphological, reproductive, and desiccation tolerance traits across several cytotypes of a single species to test for links between polyploidy and increased resilience. We sampled multiple natural populations of the resurrection grass Microchloa caffra across an environmental gradient ranging from mesic to xeric in South Africa. We describe two distinct ecotypes of M. caffra that occupy different extremes of the environmental gradient and exhibit consistent differences in ploidy, morphological, reproductive, and desiccation tolerance traits in both field and common growth conditions. Interestingly, plants with more polyploid genomes exhibited consistently higher recovery from desiccation, were less reproductive, and were larger than plants with smaller genomes and lower ploidy. These data indicate that selective pressures in increasingly xeric sites may play a role in maintaining and increasing desiccation tolerance and are mediated by changes in ploidy.

Background: Risky sexual behaviour (RSB), particularly multiple sexual partnerships (MSP) continues to be a major public health concern and has been linked to the increasing STIs, including HIV/AIDS in many parts of sub-Saharan Africa (SSA), suggesting that there is an association between contextual factors and multiple sexual partnering. However, in South Africa, this association is not well established in recent literature. Hence, this study examined the contextual factors contributing to multiple sexual partnerships among young people in South Africa. Materials and methods: Data was extracted from the 2016 South Africa Demographics and Health Survey (2016 SADHS). A cross-sectional study of 3889 never-married young people. Descriptive and inferential statistics as well as multilevel logistic regression were used to analyse the data on never-married young people aged 15 to 24 years. Results: The results indicated that at the individual level, young males (61.7%) were significantly more likely than their female counterparts (56.1%) to engage in multiple sexual partners, although, the difference was not as significant as expected. At the community level clustering, the likelihood of exposure to multiple sexual partnerships significantly increased among females (OR = 1.47; 95% CI: 1.25–1.73) but decreased among their male counterparts (OR = 0.73; 95% CI: 0.58–0.92), in particular, family disruption, residential instability, and ethnic diversity led young people to engage in multiple sexual partnerships. Conclusions: There is a need to intensify programmes aimed at considering appropriate policy options to reduce the prevalence of multiple sexual partnerships. Adopting the implications of these findings is essential for a developmental strategy towards achieving the sustainable development goal of ending STIs among young people in South Africa.

In contrast to the strained relationship between Israel and South Africa’s anti-apartheid movements in recent decades, the 1960s witnessed Israel actively championing an anti-apartheid stance. From the early 1960s onwards, various anti-apartheid groups sought assistance from Israel in their fight against white supremacy, viewing the Jewish State as a natural ally in their struggle against racism. This led to the formation of a relationship between Israel and the Pan-Africanist Congress (PAC), a significant development often overlooked in contemporary historical narratives. Despite its brevity – spanning less than a decade – this alliance offers valuable insights into African nationalism and its interaction with global Cold War dynamics, while also shedding light on Israel’s multifaceted engagement in Africa. This article aims to reconstruct this historical relationship in detail, emphasizing its significance in elucidating the intricate connections between the Arab-Israeli conflict and the racial conflict in South Africa during the 1960s.

Background: There is a substantial amount of literature on the perception of the practice environment and quality of care as perceived by registered nurses and community services nurses in South Africa and worldwide, but there is little to no research that could be found regarding other categories of nurses, and how these perceptions differ between the different categories. Therefore, the aim of this study is to describe the different nursing categories' perceptions of the practice environment and quality of care and the association between the variables. Methods: This study applied a cross-sectional survey design. Data were collected in April 2021 in the public sector of the North West Province. Multiphase sampling was applied to all categories of nurses who worked in an in-patient unit in the selected hospital for at least 3 months (n = 236). Results: All nursing categories perceived the practice environment as negative, regarding nurse participation in hospital affairs; nurse manager ability, leadership, and support of nurses and staffing and resource adequacy. Perceived quality of care and patient safety items were perceived as neutral and good. However, in all instances, the perceptions of community service nurses and registered nurses were most negative, and enrolled nurse assistants most positive. Adverse events towards patients and nurses were perceived to only occur a few times a year. Overall, nurse perceptions of quality of care and patient safety were most correlated with the subscale of nurse foundations of quality of care and nurse manager ability, leadership, and support of nurses. Adverse events towards patients were most correlated with the collegial nurse-physician relationship subscale, while adverse events towards nurses were correlated with the foundations of quality of care subscale. Conclusion: Improving the practice environment, especially regarding the subscale nurse foundations of quality of care and nurse manager ability, leadership, and support of nurses, is associated with improved quality of care. Nurses with higher qualifications, registered nurses and community service nurses rated quality of care lower than other categories of nurses, contributing to literature that higher qualified staff are more competent to assess the practice environment and quality of care.

The productivity of agricultural ecosystems is heavily influenced by soil-dwelling organisms. To optimize agricultural practices and management, it is critical to know the composition, abundance, and interactions of soil microorganisms. Our study focused on Acrobeles complexus nematodes collected from tomato fields in South Africa and analyzed their associated bacterial communities utilizing metabarcoding analysis. Our findings revealed that A. complexus forms associations with a wide range of bacterial species. Among the most abundant species identified, we found Dechloromonas sp., a bacterial species commonly found in aquatic sediments, Acidovorax temperans, a bacterial species commonly found in activated sludge, and Lactobacillus ruminis, a commensal motile lactic acid bacterium that inhabits the intestinal tracts of humans and animals. Through principal component analysis (PCA), we found that the abundance of A. complexus in the soil is negatively correlated with clay content (r = -0.990) and soil phosphate levels (r = -0.969) and positively correlated with soil sand content (r = 0.763). This study sheds light on the bacterial species associated to free-living nematodes in tomato crops in South Africa and highlights the occurrence of various potentially damaging and beneficial nematode-associated bacteria, which can in turn, impact soil health and tomato production.

Background: Treatment of carbapenem-resistant Enterobacterales (CRE) infections in low-resource settings is challenging particularly due to limited treatment options. Colistin is the mainstay drug for treatment; however, nephrotoxicity and neurotoxicity make this drug less desirable. Thus, mortality may be higher among patients treated with alternative antimicrobials that are potentially less efficacious than colistin. We assessed mortality in patients with CRE bacteremia treated with colistin-based therapy compared to colistin-sparing therapy. Methods: We conducted a cross-sectional study using secondary data from a South African national laboratory-based CRE bacteremia surveillance system from January 2015 to December 2020. Patients hospitalized at surveillance sentinel sites with CRE isolated from blood cultures were included. Multivariable logistic regression modeling, with multiple imputations to account for missing data, was conducted to determine the association between in-hospital mortality and colistin-based therapy versus colistin-sparing therapy. Results: We included 1 607 case-patients with a median age of 29 years (interquartile range [IQR], 0–52 years) and 53% (857/1 607) male. Klebsiella pneumoniae caused most of the infections (82%, n=1 247), and the most common carbapenemase genes detected were blaOXA-48-like (61%, n=551), and blaNDM (37%, n=333). The overall in-hospital mortality was 31% (504/1 607). Patients treated with colistin-based combination therapy had a lower case fatality ratio (29% [152/521]) compared to those treated with colistin-sparing therapy 32% [352/1 086]) (p=0.18). In our imputed model, compared to colistin-sparing therapy, colistin-based therapy was associated with similar odds of mortality (adjusted odds ratio [aOR] 1.02; 95% confidence interval [CI] 0.78-1.33, p=0.873). Conclusion: In our resource-limited setting, the mortality risk in patients treated with colistin-based therapy was comparable to that of patients treated with colistin-sparing therapy. Given the challenges with colistin treatment and the increasing resistance to alternative agents, further investigations into the benefit of newer antimicrobials for managing CRE infections are needed.

Background: The impact of chickens on maintaining the economy and livelihood of rural communities cannot be overemphasized. In recent years, mycoplasmosis has become one of the diseases that affect the success of South African chicken production. Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) are the most prevalent strains of Mycoplasma in South Africa. MG and MS are significant respiratory pathogens affecting the productivity of chickens. The present study aimed to molecularly detect using qPCR and characterize the presence of MG and MS using phylogenetic analysis. The phylogenetic analysis was utilized to clarify general evolutionary relationships between related taxa of different MG and MS observed in tracheal swabs from South African chicken breeds. Methods: Forty-five tracheal swabs of the Lohmann Brown (n = 9), Rhode Island Red (n = 9), Ovambo (n = 9), Venda (n = 9), and Potchefstroom Koekoek (n = 9) breeds were collected from symptomatic chickens present in the commercial farm. To detect MG and MS, DNA was extracted from tracheal swabs and faecal samples, and qPCR was performed with a 16 s rRNA (310 bp) and vlhA (400 bp) gene fragment. Following the sequencing of all the amplicons, MG, and MS dendrograms showing the evolutionary relationships among the five South African chicken breeds and the GeneBank reference population were constructed. Results: The qPCR revealed the presence of MG and MS in 22% (2/9) of the tracheal swab samples tested for MS only in Rhode Island Red breeds; 66.6% (6/9) and 33% (3/9) of the tested samples in Ovambo breeds; and 11.1% (1/9) and 44.4% (4/9) of the tested samples in Venda breeds. No MG or MS were detected in the Lohmann Brown or Potchefstroom Koekoek breed. Furthermore, qPCR revealed the presence of MG in pooled faecal samples from Lohmann Brown and Ovambo breeds. Eight different bacterial isolates were recognized from both samples. Four isolates were of the 16 s ribosomal ribonucleic acid (rRNA) gene (named PT/MG51/ck/00, PT/MG48/ck/00, PT/MG41/ck/00 and PT/MG71/ck/00) gene of Mycoplasma gallisepticum, and the other was Mycoplasma Synoviae variable lipoprotein hemagglutinin A (vlhA) gene (named PT/MSA22/ck/01, PT/MS41/ck/01, PT/MS74/ck/01 and PT/MS46/ck/01) which were available in GenBank. These isolates were successfully sequenced with 95–100% similarity to the isolates from the gene bank. Conclusion: The study revealed the presence of both MG and MS in the chicken breeds sampled. Furthermore, the different breeds of chicken were found to be susceptible to infection under the intensive or commercial management system. Therefore, continuous surveillance is encouraged to prevent the spread and outbreak of MG and MS in the poultry industry in South Africa. [ABSTRACT FROM AUTHOR]

This article provides an overview of digital archival projects and online databases developed by scholars and archival practitioners in South Africa since the early 1990s. It sketches key shifts in theory and practice over this period, including the economic and practical perils of digital conservation as heritage and of increasing civic archival activism. It shows that the outlook, aims, and successes of these projects have changed in tune with shifts in the state’s archival legislation, changing publishing economics, decreasing cost of digitisation and equipment, and widening access to the internet. Recent archival projects, such as the Five Hundred Year Archive and EMANDULO Project, illustrate a pioneering trend in South African digital archival practice and are suggestive of the formation of a distinct digital epistemic culture. The article argues that South African scholars and archival practitioners have often been at the forefront of key turns in debates taking place in digital archival practice globally and in Africa.

This study examined adherence to antiretroviral therapy (ART) among adolescents and young adults living with HIV in South Africa. Using survey data from 857 youth on ART, the study employed latent class analysis to identify subgroups based on self-reported reasons for missed ART doses. Three distinct classes emerged: the largest class (85%) occasionally forgot to take their medication or missed a dose because others were around, the second class (9%) missed doses only due to feeling sick, and the third class (6%) faced multiple barriers such as forgetting, feeling sick, worrying about side effects, or doubting the effectiveness of ART. Youth who reported multiple barriers to adherence had significantly lower adjusted odds (AOR = 0.35, 95% CI = 0.16-0.78) of reporting 90% past month adherence compared to those who occasionally forgot their medication. Additionally, contextual factors such as food security, being treated well at the clinic, and being accompanied to the clinic were associated with higher odds of adherence. The findings highlight the importance of considering co-occurring barriers to adherence and tailoring interventions accordingly. Addressing contextual factors, such as ensuring food security and providing supportive clinic environments, is also crucial for promoting optimal adherence among adolescents and young adults living with HIV.

The pace at which Next Generation Sequence data is being produced continues to accelerate as technology improves. As a result, such data are increasingly becoming accessible to biologists outside of the field of bioinformatics. In contrast, access to training in the methods of genome assembly and annotation are not growing at a similar rate. In this issue, we report on a Genome Assembly Workshop for Mycologists that was held at the Forestry and Agricultural Biotechnology Institute (FABI) at the University of Pretoria, South Africa and make available the 12 draft genome sequences emanating from the event. With the aim of making the process of genome assembly and annotation more accessible to biologists, we provide a step-by-step guide to both genome assembly and annotation, intended to encourage and empower mycologists to use genome data in their research.

Globally, limited research exists on the wellbeing of children with disabilities from their own perspectives. The investigations that are published are primarily from the perspectives of parents, caregivers or educators. In South Africa, segregated schooling systems and other social inequalities introduce complexities pertaining to the educational attainment of children with disabilities. For some children, residing in boarding schools facilitates access to education. This study quantitatively explored differences in subjective wellbeing based on whether children with physical disabilities resided in boarding schools (n = 30) or at home (n = 30). The results revealed a significantly higher level of family-related wellbeing for children residing at home (Mdn = 34.63) compared to those residing in boarding schools (Mdn = 26.37), demonstrating the need to strengthen family involvement in the lives of children at boarding schools. This research supports emerging evidence that parent involvement may be required for improved wellbeing of children who reside in boarding schools. [ABSTRACT FROM AUTHOR]

Since South Africa's first democratic election in 1994, the student leadership profile has changed dramatically at historically white universities (HWUs). Given the postapartheid South African context where this study was conducted, and how participants navigate multiple role identities within a multicultural setting, the article elucidates student leaders' self‐reflection on their role identity and draws on identity theory from the discipline of social psychology as its theoretical framework, while referencing the roles model from leadership studies.

The contamination of feed and food by heavy metals represents a significant concern for the health of both animals and humans. This study investigates the impact of geographical location on heavy metal distribution in dairy cattle feeds sourced from Free State and Limpopo, South Africa (SA). A total of 70 feed samples (40 from Free State and 30 from Limpopo) were collected from 2018 to 2019 and analyzed for heavy metals, including cadmium (Cd), arsenic (As), copper (Cu), zinc (Zn), lead (Pb), and chromium (Cr), using inductively coupled plasma mass spectrometry (ICP‐MS). Our findings revealed the presence of Cr, Cu, and Zn in the feeds, but at levels below the FAO/WHO permissible limits. Additionally, As, Cd, and Pb concentrations in the feeds were below the Limit of Detections (LODs). Generally, Cr concentrations (0.032–0.454 mg/kg) identified in the Free State samples were lower than those found in Limpopo (0.038–1.459 mg/kg), while the levels of Cu (0.092–4.898 mg/kg) and Zn (0.39–13.871 mg/kg) recorded in the Free State samples were higher than those from Limpopo [(0.126–3.467 mg/kg) and (0.244–13.767 mg/kg), respectively]. According to independent sample t‐tests, Cu and Zn levels were substantially higher (p ≤.05) in Free State feeds compared to Limpopo, while Limpopo feeds exhibited significantly higher (p ≤.05) Cr concentrations than Free State feeds. Despite the low recorded heavy metal levels, regular monitoring of these elements in cow diets across all SA provinces is essential for ensuring the well‐being of animals and humans.

Phymatolithon acervatum is an encrusting, non-geniculate coralline alga from South Africa. While morpho-anatomical details of the species are well documented, no genetic analyses have been performed on P. acervatum. Here, we analyzed rbcL and psbA gene sequences, and they showed that two species were passing under the name Phymatolithon acervatum in South Africa. A partial rbcL sequence from the lectotype of Lithothamnion acervatum, basionym of P. acervatum, showed to which species the specific epithet applies, and furthermore that both species belong in Phymatolithopsis. We transfer Phymatolithon acervatum to Phymatolithopsis, as Phymatolithopsis acervata comb. nov., and propose Phymatolithopsis roseola sp. nov. These species overlap in morpho-anatomy, habitat and distribution and can only be distinguished based on DNA sequences. Previous misinterpretations of conceptacle development are corrected for species of Phymatolithopsis. The main character used to define the family Mesophyllumaceae is shown to have arisen several times in independent lineages in the order Hapalidiales. At present, only one family, Hapalidiaceae, thus merits recognition in the Hapalidiales. [ABSTRACT FROM AUTHOR]

Carex dianae Steud. is an endemic sedge of St. Helena, an isolated island in the South Atlantic. Our study provides the first molecular sequence data for this taxon. We generated sequence data for plastid matK and trnK regions and nuclear internal transcribed spacer and external transcribed spacer regions to determine the placement of C. dianae in the broader Carex phylogeny. The placement of C. dianae falls within Carex sect. Spirostachyae Drejer, and it is sister to a clade including Carex clavata Thunb., Carex aethiopica Schkuhr (both from the Cape region of S. Africa), and Carex gunniana Boott (southern Australia). The existence of three divergent nucleotype groups and two plastotypes is revealed from genetic variation within C. dianae. The results suggest that the ancestor of C. dianae likely originated in the Cape region of South Africa, followed by transoceanic dispersal to St. Helena estimated at 4.4–4.9 million years ago, likely by a bird vector. The most divergent population is that on an isolated hill known as "The Barn", which may represent a distinct taxon. The existence of highly structured molecular variation within an island only 16 km long is discussed. [ABSTRACT FROM AUTHOR]

This study explored how a non-linear coaching model can be used to develop headteachers in South Africa on their learning journey. The case study explores through qualitative data how senior leaders in schools were able to reflect on their learning through the use of a non-linear coaching model to deepen their understanding of senior leadership, and how they strategically needed to consider the needs of their school, as well as the learners and teams within their schools. A qualitative research approach was used, with data from semi-structured interviews thematically coded through the use of Braun and Clarke's (2006) six phase model. Key learning from the project is that a collaborative professional approach, facilitating effective learning conversations through a non-linear model, ensured that leaders were able to develop a deep understanding of their contexts and were able to engage with key strategic decisions making processes in a safe, trusting learning environment.

Phenomenon: Professionalism as a construct is weaponized to police and punish those who do not fit the norm of what a medical professional should look like or behave, more so when medical professionals in training engage in protests for social justice. In addition, professionalism silences trainees, forcing them not to question anything that looks or feels wrong in their eyes. Socialization in medicine, in both the undergraduate and postgraduate training spaces, poses challenges for contemporary medical professionals who are expected to fit the shape of the 'right kind of doctor.' Intersectionality seems to impact how medical trainees experience professionalism, be it intersections of gender, race, how they dress or adorn themselves, how they carry themselves and who they identify as. Although there is literature on the challenges pertaining to professionalism, not much has been written about the weaponization of professionalism in medical training, particularly in the South African context. There is also a paucity of data on experiences of professionalism during or after social upheaval. Approach: This is part of a study that explored the experiences of professionalism of five medical trainees during protests and after protests, extending into their postgraduate training. The main study had 13 participants, eight students and five graduates, who were all interviewed in 2020, five years after the #FeesMustFall protests. For the five postgraduate participants, we looked at how gender, race, hairstyles, adornment, and protests played out in the experiences of professionalism as medical trainees at a South African university. We employed a qualitative phenomenological approach. An intersectional analytical lens was used in analyzing the transcripts of the five graduate participants. Each transcript was translated as the story of that participant. These stories were compared, looking for commonalities and differences in terms of their experiences. Findings: The participants, four males (three Black and one white) and one Black female, were victimized or judged based on their activism for social justice, gender, and race. They were made to feel that having African hairstyles or piercings was not professional. Insights: Society and the medical profession has a narrow view of what a doctor should look like and behave – it should not be someone who wears their hair in locks, has body piercing, or is an activist, least of all if she is a woman, as professionalism is used as a weapon against all these characteristics. Inclusivity should be the norm in medical education. [ABSTRACT FROM AUTHOR]

Land reforms have been implemented in many parts of the world because of both justice and the attractive developmental policy objectives of improving poor people's welfare – as the prime beneficiaries. Land reform also facilitates rural economic growth. In some parts of the world, like China and India, there is evidence that land reform has been effective in poverty reduction and in enabling economic growth. However, in other parts of the world, like South Africa, the impact of land reform has been very minimal mainly due to poor policy implementation, which entails inadequate support structures. Using an integrative literature review approach and key policy documents on South Africa's land reform, this article dissects this policy–practice gap in South Africa's land redistribution policy and proposes that land redistribution be implemented by a private independent entity to reduce state bureaucracy and inefficiencies and, in turn, improve execution.

South Africa's 2030 National Development Plan (NDP), which is a long-term policy and development strategic guideline, places agriculture at the centre of employment creation. It estimates that a million jobs could be created through the agricultural sectors, including the smallholder farming sector. Considering the NDP's goal, this viewpoint unpacks how smallholder agricultural labour supply has evolved over time and highlights the implications of this vigorous change. In doing so, it traces this evolution back to the kinships that have kept rural African communities together for many years. The viewpoint also raises looming issues for discussion by policymakers and development practitioners. To effectively develop rural communities it is important to understand and appreciate the rural sociological realities that are behind the remarkable changes in the use of labour in smallholder agriculture. The viewpoint is based on the author's long-term engagement with smallholder farmers in his previous works. [ABSTRACT FROM AUTHOR]

We investigated the evolutionary patterns of two forest-dwelling endemic terrestrial snails (Gittenedouardia spadicea and Maizania wahlbergi) in the Maputaland–Pondoland–Albany biodiversity hotspot in South Africa to examine the degree of phylogeographical congruence between the two species. Phylogenetic relationships and divergence time estimations within each species were inferred using the combined mitochondrial DNA (mtDNA) sequence dataset for the cytochrome c oxidase subunit I (COI) and large subunit ribosomal RNA (16S rRNA). In addition, the rapidly evolving COI datasets were used to infer intraspecific genetic structure and population differentiation within both species. Phylogeographical concordance factor (PCF) analysis was used to statistically estimate the degree of congruence between the two species at localities where both species were sampled. Phylogenetically, G. spadicea exhibited two clades that diverged during the Plio/Pleistocene, while M. wahlbergi formed a single shallow clade that showed Pleistocene divergence. The haplotype networks for the COI locus demonstrated evidence of geographical and genetic isolation within both species. PCF analysis demonstrated partial phylogeographical concordance, suggesting that the two species may have been affected by similar ancient climatic events. Traits other than poor dispersal capabilities and limited gene flow may also influence how a species responds to fluctuating climate change. [ABSTRACT FROM AUTHOR]

Marked differences in the prevalence of allergy between urban and rural environments have been well established. Certain microorganisms encountered in and around farming and rural surroundings can 'train' and modulate the human immune system to protect against certain infectious and non-communicable diseases, including allergies. Research from South Africa has indicated that drinking fermented cow's milk from a young age may protect against allergy even in a urban population. Lactic acid bacteria are important role-players in allergy protection and these organisms are abundant in fermented food products. The questions arise: Can people living in urban areas, at least to some extent, 'replicate' the allergy protective environment of rural people or at least compensate for a lack of exposure to protective organisms? And can they do so safely? In this review we focus on fermented milk and other fermented foods and elaborate on the allergy-protective microbiota favoured by fermentation. [ABSTRACT FROM AUTHOR]

New mapping of the Barberton Greenstone Belt in South Africa shows that the central part is a pseudo-stratigraphy made of shallow-water and deep-water siliciclastic and volcanic slide blocks, with individual blocks ranging in size from tens of meters to >10 km in length. The outcrop pattern and scale are remarkably similar to those of large-scale Miocene to recent submarine landslides in New Zealand along the active Hikurangi subduction zone that are periodically triggered by earthquakes on the subduction megathrust, providing evidence for megathrust earthquakes in the Paleoarchean.

Introduction Congenital syphilis (CS) is preventable through timely antenatal care (ANC), syphilis screening and treatment among pregnant women. Robust CS surveillance can identify gaps in this prevention cascade. We reviewed CS cases reported to the South African notifiable medical conditions surveillance system (NMCSS) from January 2020 to June 2022. Methods CS cases are reported using a case notification form (CNF) containing limited infant demographic and clinical characteristics. During January 2020–June 2022, healthcare workers supplemented CNFs with a case investigation form (CIF) containing maternal and infant testing and treatment information. We describe CS cases with/without a matching CIF and gaps in the CS prevention cascade among those with clinical information. Findings During January 2020–June 2022, 938 CS cases were reported to the NMCSS with a median age of 1 day (interquartile range: 0–5). Nine percent were diagnosed based on clinical signs and symptoms only. During January 2020–June 2022, 667 CIFs were reported with 51% (343) successfully matched to a CNF. Only 57% of mothers of infants with a matching CIF had an ANC booking visit (entry into ANC). Overall, 87% of mothers were tested for syphilis increasing to 98% among mothers with an ANC booking visit. Median time between first syphilis test and delivery was 16 days overall increasing to 82 days among mothers with an ANC booking visit. Discussion Only 37% of CS cases had accompanying clinical information to support evaluation of the prevention cascade. Mothers with an ANC booking visit had increased syphilis screening and time before delivery to allow for adequate treatment. [ABSTRACT FROM AUTHOR]

Background: We analyzed the STREAM (Simplifying HIV TREAtment and Monitoring) study to determine risk factors associated with HIV viraemia and poor retention 18 months after initiation of antiretroviral therapy (ART). Methods: The STREAM study was an open‐label randomized controlled trial in Durban, South Africa, that enrolled 390 people living with HIV presenting for their first HIV viral load measurement ~6 months after ART initiation. We used modified Poisson regression with robust standard errors to describe associations between baseline characteristics and three HIV outcomes 18 months after ART initiation: HIV viraemia (>50 copies/mL), poor retention in HIV care, and a composite outcome of poor retention in care and/or HIV viraemia. Results: Approximately 18 months after ART initiation, 45 (11.5%) participants were no longer retained in care and 43 (11.8%) had viraemia. People with CD4 counts <200 and those with viraemia 6 months after ART initiation were significantly more likely to have viraemia 18 months after ART initiation (adjusted relative risk [aRR] 4.0; 95% confidence interval [CI] 2.1–7.5 and aRR 5.5; 95% CI 3.3–9.0, respectively). People who did not disclose their HIV status and had viraemia after ART initiation were more likely to not be retained in care 12 months later (aRR 2.6; 95% CI 1.1–6.1 and aRR 2.2; 95% CI 1.0–4.8). People with a CD4 count <200 and those with viraemia were more likely to not achieve the composite outcome 18 months after ART initiation. Conclusions: Viraemia after ART initiation was the strongest predictor of subsequent viraemia and poor care retention. Understanding early indicators can help target our interventions to better engage people who may be more likely to experience persistent viraemia or disengage from HIV care. [ABSTRACT FROM AUTHOR]

John D. Brewer's (1994) seminal study of the South African Police claimed that structural factors would inhibit democratic reforms in law enforcement agencies, regardless of which political party controlled the public administration. Thirty years of majority rule, and a series of subsequent works (Altbeker 2005, 2007; Steinberg, 2008; Lamb 2018), demonstrate that Brewer's thesis remains relevant. Occasional efforts at fully reconstructing state security agencies never took hold and the South African Police Service remains mired in the sordid practices of its colonial past. McMichael and Brown concur with this established narrative while Shaw's study on vigilantism adds insightful subtleties that deromanticize subaltern social movements. All three authors tackle sharp distinctions between policing and criminality, arguing that the two processes often intertwine and are frequently interchangeable. This review article combines structural determinants of coercive law enforcement with elite political agency. Political choices made by South Africa's ruling African National Congress reinforce criminal practices in policing and precipitate the formation of volatile vigilante organizations.

Public procurement is often used to achieve policy goals beyond the purchase of the required goods and services. These goals include the economic advancement of minorities, the promotion of fair labour practices and climate action. In the last two decades, many countries have used public procurement to advance gender equality. This is referred to as gender-responsive procurement and is often implemented through the award of public contracts to women-owned businesses. While many countries have legal provisions designed to increase the award of public contracts to women, gender-responsive procurement is extremely limited and women-owned businesses are not fully integrated into public sector supply chains. This is unfortunate, given that gender-responsive procurement can improve women's economic empowerment, with implications for sustainable development. This article adopts a gender equality and women's economic empowerment lens to examine the legal, policy and cultural barriers to gender-responsive procurement and recommends measures to improve the award of public contracts to women-owned businesses.

This article explores the remaking of administrative law review in South Africa since the introduction of constitutional democracy in 1994. It characterizes the construction of the constitutional and legislative framework, as well as the courts' interpretation of that framework, as the first phase of the remaking. The second phase encompasses the courts' recognition of a constitutional principle of legality based on the rule of law, and their swift development of the content of this principle. This judicial creativity has resulted in an elaborate avenue to review, parallel to the Promotion of Administrative Justice Act 3 of 2000, and has caused problems of rivalry and avoidance. The article identifies and discusses some of the more significant implications of each of these phases of reconstruction. It also proposes corrective measures likely to advance the coherence and effectiveness of judicial review and discourage the adoption of a doctrine of non-justiciability. [ABSTRACT FROM AUTHOR]

This article examines the interplay between traditional leaders, democratically elected leaders and succession in Makapanstad Village, North West Province, South Africa. The article stems from community-based participatory action research conducted in Makapanstad in 2018. The article uses research data, in the form of community dialogue, together with desktop literature on the same subject. The article analyses the significance and role of traditional leadership in a democratic South Africa. It considers traditional leadership and democratically elected leadership in conjunction with succession and the demarcation of roles and responsibilities. The article analyses participants' views to explore the form of leadership preferred by the residents of Makapanstad. It argues that, despite the recognition of traditional leadership in South Africa's Constitution, the roles and responsibilities of traditional leaders in local and provincial arms of government are limited, in contrast to those of democratically elected leaders.

Quantitative studies have explored the work abilities of persons with specific vestibular-related symptoms, but there seems to be a dearth of research that has explored the work experience of persons-with- vestibular- disorders, so this qualitative study explored this phenomenon. Audio-recorded semi-structured interviews were conducted online. Thematic analysis was used to analyse the transcripts. Together, two researchers coded the transcripts and deductively identified the main themes on the main components of the expanded International Classification of Functioning, Disability, and Health scheme, and thereafter generated the sub-themes inductively. Fourteen people with various vestibular disorders and occupations in South Africa participated in the study. Participants reported having difficulty performing work-related tasks requiring attention to detail and ambulation, and work environmental conditions triggered their vestibular-related symptoms. Some participants received time off from work and support from their supervisors and colleagues, while others did not. Seeking mental services allowed them to overcome their negative feelings, medication suppressed their vestibular-related symptoms, and vestibular rehabilitation allowed them to focus on their work. Vestibular-related symptoms may hinder persons- with- vestibular- disorders from completing and participating in work-related activities, which may result in them experiencing negative feelings. The nature of some of the work-related tasks that they need to complete and experiencing negative feelings may trigger their vestibular-related symptoms. Together, the work-related activity limitations, participation restrictions, and environmental and personal factors may cause persons- with- vestibular- disorders to experience disability in their workplaces. To prevent this potential disability, persons with vestibular disorders should be supported by and receive workplace accommodations. Furthermore, they should be enrolled into work rehabilitation programmes that include, vestibular rehabilitation, medication regimens, and mental health services. [ABSTRACT FROM AUTHOR]

Mobile health (mHealth) interventions for mental health and well-being have increased exponentially in recent years. In this digital era, mHealth interventions are proving to be a useful tool in the promotion of mental health for university students. This mixed-methods study explored the feasibility, practicality, and acceptability of a mental health application (app) designed to address mental health challenges among university students. Overall, a total of 1100 participants completed an online survey, and data were analysed using statistical analytics software. Most of the participants were female (72.73%) within the 18–20 age group (64.64%) and in their first year of study (46.18%). The results show that at least 98.7% of the participants owned a smartphone, 80.8% had access to mobile data, 66.9% used Android software, 20.09% had historically been diagnosed with a mental health challenge, and 26.6% had used an online health app. Sixty-two participants were enrolled across 16 focus group discussions. Qualitative data were analysed using thematic analysis, which revealed four facilitators of app acceptability (exposure to mental health apps, convenience, accessibility, and confidentiality) and three barriers to app acceptability (preference for face-to-face therapy, overreliance on app, and fear of misdiagnosis). The findings suggest that an app that is convenient, accessible, confidential, and nonpathologising can be a feasible and acceptable intervention to address mental health challenges.

Unemployment is a global phenomenon that is affecting many individuals and families negatively, in particular, their functioning, well-being, and coping mechanisms. Unemployment is thus regarded as a risk factor that places many families in adverse situations. While literature extensively describes family resilience in the face of diverse adversities, little research documents family resilience in the face of unemployment, especially in South Africa. It is within this context that we set out to explore the adversity of unemployment from a resilience perspective with the intention to unmask the embedded protective processes in affected families. This was approached through the loose application of Walsh's family resilience perspective as a theoretical lens. In-depth, semi-structured interviews were conducted with nine participants who were regarded as breadwinners or key family providers. Each participant engaged in two interviews that were four months apart to allow for reflection and member checking. Data were analysed through a hybrid process that incorporated both the inductive and the deductive logic of thematic analysis. Participants described several key protective processes, which aligned with what Walsh proposed. The practice of communicating, the ability to connect, and the use of spirituality were identified as particularly useful. Overall, the findings imply that despite the experienced adverse conditions of unemployment, South African families demonstrate thriving potential. [ABSTRACT FROM AUTHOR]

One of the major concerns of development in Africa is the issue of public health. In Africa, public healthcare has been and still is a problem most African countries are faced with. The problem of public healthcare seems to be unabated even though there are measures that are put in place for its effectiveness. There is hunger, malnutrition, high mortality rate, illnesses and deterioration of life expectancy in most developing countries of Africa. The dramatic unprecedented public health disparity has become a scourge in developing countries where it has purportedly impaired the developmental efforts, economic growth and prosperity. As a result, there is a need to scrutinize possible causes that exacerbates public health issues in developing countries. The paper argues that the current food production system (conventional) contributes to current status of public health as compared to the previous food production system (organic). The purpose of this paper is to conceptualize public healthcare disparities, juxtaposing organic and conventional food production that result as human food consumption. The paper employs literature-based analysis as a methodology to assemble data in respect of public healthcare disparities and food production systems. [ABSTRACT FROM AUTHOR]

This article contributes a boundary work analysis of the case of acid mine drainage (AMD) in South Africa to the existing boundary work literature. We conduct our analysis by applying a synthesized multi-level boundary work framework to examine whether the knowledge that was produced during the boundary work conducted was usable and influential in decision-making and resulted in successful policy implementation. We conclude that contrary to expectations, a closed, technocratic boundary work process resulted in the relatively successful implementation of a short-term intervention in the AMD problem, whereas a subsequent open and deliberative process did not result in the successful implementation of the long-term policy solution. We ascribe this finding to the influence of critical enabling and constraining factors characterizing the South African socio-political context within which the AMD issue is situated, and therefore, we recommend adding a meta-analytical layer to boundary work analyses, especially in developing country contexts.

To deepen our understanding of the impact of the COVID-19 pandemic on intimate and/or sexual relationships, we conducted a qualitative study among 26 South African women and men aged 21–30 years in Durban and Soweto between September 2020 and March 2021. Overall, 13 women and 12 men who had been in an intimate and/or sexual relationship since the start of the COVID-19 pandemic were asked about the impact of COVID-19 on their relationships with their current or most recent primary partners. Data were analysed using reflexive thematic analysis. The three most common impacts of the COVID-19 pandemic on relationships were on (i) communication and connection; (ii) strained relationships; and (iii) job and economic loss. Both women and men discussed how COVID-19-related lockdowns provided opportunities to foster better communication, connection and support to one another. However, too little or too much time together strained relationships. Finally, income loss among young men meant that some young women became the primary income earner, changing relationship power dynamics. Findings highlight the importance of young people's relationships and the need for action to support young people in building positive relationships in challenging times. [ABSTRACT FROM AUTHOR]

In November 2021, South Africa signed the first international Just Energy Transition Partnership (JETP). This unlocked 8.5 billion USD in donor funding (primarily loans) to decarbonise its economy. The processes and substance of this decarbonisation have been criticised by unions and by civil society. This article traces the stakeholder consultation process through which civil society encouraged marginal improvements while broadly legitimising the JETP, and it details the causes and implications of South African unions' decreased engagement with the Just Transition. The article argues that the specifics of civil society's engagement with multistakeholder consultations, and organised labour's disengagement, work towards legitimising a donor- and market-led transition. In partially explaining why a powerful civil society and the labour movement have not demanded more radical change, the article highlights tensions between the 'professional class' that dominates responses to climate change and a workers' movement where political power is deeply tied to identarian mobilisation.

Objectives: Transfers between health facilities of people living with HIV attending primary health care (PHC) including hospital to PHC facility, PHC facility to hospital and PHC facility to PHC facility transfers occur frequently, affect health service planning, and are associated with disengagement from care and viraemia. Data on transfers among people living with diabetes attending PHC, particularly transfers between PHC facilities, are few. We assessed the transfer incidence rate of people living with diabetes attending PHC, and the association between transfers between PHC facilities and subsequent HbA1c values. Methods: We analysed data on HbA1c tests at public sector facilities in the Western Cape Province (2016–March 2020). Individuals with an HbA1c in 2016–2017 were followed‐up for 27 months and included in the analysis if ≥18 years at first included HbA1c, ≥2 HbA1cs during follow‐up and ≥1 HbA1c at a PHC facility. A visit interval was the duration between two consecutive HbA1cs. Successive HbA1cs at different facilities of any type indicated any transfer, and HbA1cs at different PHC facilities indicated a transfer between PHC facilities. Mixed effects logistic regression adjusted for sex, age, rural/urban facility attended at the start of the visit interval, disengagement (visit interval >14 months) and a hospital visit during follow‐up assessed the association between transfers between PHC facilities and HbA1c >8%. Results: Among 102,813 participants, 22.6% had ≥1 transfer of any type. Including repeat transfers, there were 29,994 transfers (14.4 transfers per 100 person‐years, 95% confidence interval [CI] 14.3–14.6). A total of 6996 (30.1%) of those who transferred had a transfer between PHC facilities. Visit intervals with a transfer between PHC facilities were longer (349 days, interquartile range [IQR] 211–503) than those without any transfer (330 days, IQR 182–422). The adjusted relative odds of an HbA1c ≥8% after a transfer between PHC facilities versus no transfer were 1.20 (95% CI 1.05–1.37). Conclusion: The volume of transfers involving PHC facilities requires consideration when planning services. Individuals who transfer between PHC facilities require additional monitoring and support.

This conceptual article argues for the need to reframe approaches to the South African food crisis in terms of decolonizing the food system. The point of departure is that the South African food system produces starkly unequal access to nutritious food, negative health outcomes, environmental destruction and a breakdown in social relations. The harms of this system disproportionately affect the poor, Black people and women. The historical roots of this unjust food system lie in colonialism, capitalism and apartheid, yet this coloniality continues in its modern global industrial incarnation. The colonial, capitalist values underpinning the food system have been normalized and have become hegemonic. This leaves little space for imagining – or fighting for – more just alternatives. Yet the framework of decolonization has the potential to create such a space to begin to challenge the hegemony of the current (neo)colonial/capitalist food system and replace the profit motive with the values of reciprocity, collectivity and inter-connectedness that underpinned pre-colonial food systems.

This cross-sectional study aimed to explore the use of alcohol and drugs and the potential impact on adherence to medication for tuberculosis. Adult patients admitted to specialised tuberculosis hospitals in South Africa were assessed for drug use, alcohol use and adherence to tuberculosis medication. A total of 175 patients participated in the study; 32% reported harmful alcohol use, and 44% reported problematic use of drugs. Participants who used drugs were four times as likely (OR = 4.11, 95% CI (1.89, 8.91)) and those using alcohol were twice as likely (OR = 2.06, 95% CI (1.02, 5.08)) to be nonadherent to medication for tuberculosis. Prevalence of harmful/hazardous use of alcohol and other drugs was high and significantly correlated with poorer medication adherence. Routine screening for and treatment of substance use in patients on treatment for tuberculosis and ongoing monitoring of adherence to medication is recommended. [ABSTRACT FROM AUTHOR]

• Annesorhiza tilneyae Magee & Maswoliedza is formally described. • validate the name Annesorhiza asparagoides B.-E. van Wyk. • 23 species of Annesorhiza now recognised. • Identification key to all species within the genus provided. Annesorhiza Cham. & Schltdl. (Apiaceae) comprises ca. 23 species endemic to South Africa. The genus is centred in the Greater Cape Floristic Region, with only four species occurring in the summer rainfall regions. In the two decades since Annesorhiza was last revised, the number of recognised species has almost doubled, with 8 species subsequently described and another two transferred to the genus. The high number of new species in the genus can be attributed to the hysteranthous habit, with plants leafless at the time of flowering and fruiting, and that these species are rare, highly localised endemics. Species of Annesorhiza are often overlooked as they flower largely during the dry summer months, and multiple visits are required in order to recover a complete collection for accurate identification. Here we describe another new species from the Bokkeveld Mountains, Annesorhiza tilneyae Magee & Maswoliedza. We also validate the name Annesorhiza asparagoides B.-E. van Wyk with reference to the previously and effectively published descriptions and diagnoses. With several Annesorhiza species described since the last revision, we also provide an updated identification key to all species within the genus. [ABSTRACT FROM AUTHOR]

There is a paucity of studies demonstrating how small and medium-sized enterprises (SMEs) adopt CSR interventions to enhance social and economic conditions of communities within which they operate. There is also a prevailing stereotype that Corporate Social Responsibility is only applicable to big, multinational companies. The study therefore explored the knowledge, attitudes, and practices of 10 owners of SMEs in Johannesburg, South Africa regarding CSR. Guided by a social development lens, the study adopted a qualitative case study research design. Thematic analysis of interview responses revealed that most of these owners considered their SMEs to be practising CSR, and were motivated primarily by the intrinsic spirit of Ubuntu rather than extrinsic compliance with regulatory requirements. While some CSR interventions (such as skills-transfers as empowerment) were found to be consistent with the social development approach, others, such as philanthropy, were not necessarily developmental but nevertheless important in a developing country such as South Africa with its high levels of poverty. The key contributions of the study to knowledge are first, that it debunks the misconception in the literature that SMEs are too small and financially incapable of implementing CSR interventions; and second, that it enhances understanding from a developing world perspective of the factors motivating SME owners to engage in CSR.

The lack of women in leadership across higher education has been problematised in the literature. Often, contemporary discourses promote "fixing the women" as a solution. Consequently, interventions aimed at helping women break through "the glass ceiling" abound. We argue that the gendered power relations at play in universities cause entrenched inequalities to remain in place, regardless of measures implemented for and by women. This article reports on a study of the impact of COVID-19 on 2029 women academics in South Africa. We examine how academic women's roles as nurturers at home are extended to their roles as carers at work, and how these impact their prospects for career progression. The article further shows how expectations placed on women academics as carers contribute to gendered dimensions of inequality that are detrimental to both their own well-being and careers. Finally, we call on higher education institutions to "fix themselves", rather than "the women", if they want to dismantle gender inequalities. [ABSTRACT FROM AUTHOR]

South Africa has two fully privatised prisons, each housing some 3,000 prisoners. Their history has been mired in controversy from the start, and this has not improved over a period of nearly 25 years. Recent events affecting the security and integrity of the two facilities provide a useful opportunity to reflect on these private prisons as well as wider issues regarding private sector involvement in the prison system. The intersection of politics, organised labour, private sector interests, and corruption have in all likelihood rung the death knell for private prisons in South Africa. [ABSTRACT FROM AUTHOR]

Fungi in the Cryphonectriaceae are important canker pathogens of woody shrubs and trees in the Melastomataceae and Myrtaceae (Myrtales). During 2021 disease surveys in KwaZulu‐Natal (South Africa) plantations, a serious stem canker disease was discovered on species of Eucalyptus and Corymbia. The cankers had structures on their surfaces typical of fungi in the Cryphonectriaceae. The aims of the study were to identify the fungus associated with the disease and to test its pathogenicity. Morphological characteristics of both sexual and asexual structures and phylogenetic analyses based on partial sequences of the conserved nuclear large subunit (LSU) ribosomal DNA, the internal transcribed spacer (ITS) regions including the 5.8S gene of the ribosomal DNA operon, and two β‐tubulin (BT1/BT2) regions were used for identification purposes. Phylogenetic analyses of the sequence data and morphological characteristics supported the establishment of a new genus in the Cryphonectriaceae, for which the name Xanthoporthe myrticola gen. et sp. nov. is provided. Pathogenicity trials showed that isolates were pathogenic on tested Eucalyptus grandis and hybrids as well as Corymbia henryi. The results suggest that this is an emerging pathogen that could influence the sustainability of plantation forestry in South Africa. [ABSTRACT FROM AUTHOR]

Sclerotinia head rot, caused by Sclerotinia sclerotiorum, is a major disease limiting sunflower production in tropical and subtropical agroecological zones. Sporadic outbreaks across South Africa have resulted in major losses, yet little is known about the in‐field climatic factors driving this infection. Short‐interval, staggered plantings have been proposed as a control method for Sclerotinia head rot, which help to limit the number of plants in a susceptible developmental stage during conducive environmental conditions. However, this complicates field management practices, especially if working at the fringes of a planting window due to delayed rains. This study aimed to investigate the effect of planting date on Sclerotinia head rot progression in monthly plantings across the summer period. Artificial mycelial plug inoculations were performed at the R5.9 flowering stage in an open field. Disease establishment, progression and severity were monitored at 3‐day intervals for 30 days. We show that disease establishment was delayed by low relative humidity or extreme low temperatures in the January and March planting dates where the first lesions were only observed 6 days post‐inoculation. Consistently high temperatures above 27°C also suppressed disease progression and produced low area under the disease progress curve (AUDPC) scores of 75.15 and 29.4 for the October and November planting dates, respectively. These findings suggest that regardless of season or location, selecting a planting date that ensures the sunflower bloom period aligns with the hottest, driest part of the season will probably suppress Sclerotinia head rot in regions with average summer highs above 27°C.
