Dry rot disease is one of the main postharvest diseases caused by Fusarium species. Several pathogenic Fusarium species have the potential to be carried on imported citrus fruits. This study aims to detect, isolate, identify, and test the pathogenicity of Fusarium species from imported citrus fruits. Fusarium species were isolated using the Overnight Freezing Incubation technique (ONFIT) method by freezing citrus fruits at -- 20°C for 15 hours. Fusarium species were identified morphologically and molecularly. Morphological identification was conducted macroscopically and microscopically by observing the characteristics of the colony on PDA media and conidia. Molecular identification was carried out by the Polymerase Chain reaction (PCR) method using universal primers of ITS1 and ITS4. Pathogenicity was tested by injecting 100 µl of fungal conidia suspension with a density of 105 conidia/ml into healthy citrus fruits. The results showed that 3 Fusarium species were successfully isolated and identified as Fusarium equiseti, Fusarium lateritium, and Fusarium oxysporum. The pathogenicity test proved that all Fusarium species were pathogenic to citrus fruits. The disease incidence of all Fusarium species was 100%. The disease severity caused by F. equiseti, F. lateritium and F. oxysporum were 73.33, 93.33 and 84.44%, respectively. These results are a new report of 3 Fusarium species causing dry rot disease in citrus fruits. [ABSTRACT FROM AUTHOR]

Aphid-borne viral infection is a major limiting factor for groundnut production in South Sulawesi, Indonesia. The study aimed to elucidate the effectiveness of integrated management packages (IMP) in controlling aphid-borne viruses infecting groundnut in the field. Field trials were conducted in a plot without (M0) and with plastic mulch and maize as a plant barrier (M1), while two different groundnut varieties, Bougainvillea leaf extract, and insecticides were incorporated as the subplot treatments. The treatments in M1 plot significantly reduced the aphid population (17.4-79.9%) and AUDPC incidence (51.7-87.3%), and severity (61.0-92.9%), respectively. The treatments increased dry pod production by 11.9-63.3% depending on subplot treatment compared to treatments in the M0 plot (p>0.05). Bean common mosaic virus strain PSt and Cowpea Polerovirus 2 were positively detected in groundnuts as well as in aphids using RT-PCR. Further, nine weed species in the vicinity of the field trial were found to be positively infected with BCMV-PSt, indicating their crucial role as reservoir hosts. Interestingly, the effectiveness of Bougainvillea leaf extract treatment in the M1 plot was comparable to that of the insecticide treatment, indicating that this IMP is a more cost-effective, eco-friendly groundnut virus control than the currently used method.
