Abstract

Contexto: El sorgo es un hospedante de Melanaphis sacchari/sorghi. Las medidas de control contra este insecto incluyen el tratamiento a semillas. Sin embargo, se necesitan evaluaciones sobre el efecto de los insecticidas en poblaciones del insecto y las variables agronómicas del cultivo. Objetivo: Evaluar la influencia de los insecticidas clothianidin, tiametoxan e imidacloprid en tratamiento a la semilla del híbrido 85 P15 (Pioneer®) sobre variables agronómicas del cultivo y la infestación de M. sacchari/sorghi. Métodos: El experimento se realizó en la Escuela de Estudios Superiores de Xalostoc, México, durante el 2018. Se utilizaron cuatro dosis de Poncho®, Cruiser® 5 FS y Tools® TS para tratar semillas del híbrido 85 P15 (Pioneer®). El diseño experimental fue bloques al azar y se determinó el porcentaje de germinación, la infestación de M. sacchari/sorghi y parámetros agronómicos del cultivo. Resultados: Todos los tratamientos tuvieron más del 90 % de germinación, lo que demuestra que los productos y dosis no afectaron este parámetro. Igualmente, no se apreciaron diferencias entre los tratamientos. El uso de estos insecticidas en semillas del híbrido influye poco sobre la infestación del pulgón. Estos tratamientos no afectan el contenido de clorofila, pero si otros parámetros como el grado Brix y el peso fresco de las hojas. Conclusiones: El tratamiento a las semillas no disminuye el porcentaje de germinación del híbrido 85 P15 (Pioneer®), no logró un control contundente sobre la infestación del pulgón, pero afecta algunas variables agronómicas por lo que se recomienda evaluar otros híbridos.

Abstract

Context: Sorghum is a hosting plant of Melanaphis sacchari/sorghi. The control measures against the insect include the treatment of seeds. However, evaluation of the effect of insecticides on insect populations and the agronomic variables of the crop, are needed. Aim: To evaluate the influence of insecticides clothianidin, thiamethoxan, and imidacloprid during the treatment of hybrid 85 P15 (Pioneer®) seeds on the agronomic variables of the crop and infestation with M. sacchari/sorghi. Methods: The experiment was conducted in the School of Higher Studies in Xalostoc, Mexico, in 2018. Four doses of Poncho®, Cruiser® 5 FS, and Tools® TS in the treatment of hybrid 85 P15 (Pioneer®) seeds. A randomized block experimental design was applied, and the percentage of germination, M. sacchari/sorghi infestation, and agronomic parameters of the crop, were determined. Results: All the parameters achieved more than 90% of germination, which demonstrated that the products and doses did not affect this parameter. Likewise, no differences were observed in the treatments. The use of these insecticides in hybrid seeds had a little influence on aphid infestation. These treatments do not affect the content of chlorophyll, but other parameters, like Brix degree, and the fresh leaf weight were affected. Conclusions: The seed treatment does not reduce the percentage of germination of 85 P15 (Pioneer®) hybrids, a strong control was not achieved over infestation of aphids, but it did affect some agronomic variables; hence, evaluation of other hybrids is recommended.

Abstract

El presente estudio se realizó en los meses de junio-julio del 2017, con el propósito de determinar la presencia de virus asociados al cultivo del sorgo (Sorghum bicolor (L.) Moench). Se muestrearon 21 localidades, distribuidas en 10 municipios de los 33 que forman el Estado de Morelos. Se utilizaron dos anticuerpos para detectar las enfermedades Virus de la hoja amarilla de la caña de azúcar (SCYLV) y Virus mosaico de la caña de azúcar (SCMV). Se analizaron muestras de follaje colectadas al azar en cinco puntos de cada campo o parcela. El diagnóstico se realizó mediante el test inmunoenzimático tipo DAS-ELISA (doble anticuerpo), con un set de reactivos AGDIA (2017), con conjugado de fosfatasa alcalina para (SCMV) y el segundo set de reactivos de NANO Diagnostic (2017) "AC Diagnostic" con conjugado fosfatasa alcalina para (SCYLV). Los resultados obtenidos evidenciaron presencia de ambas enfermedades virales en el cultivo del sorgo para el estado de Morelos. Con muestras positivas al (SCYLV) y absorbancias altas (1,50 A° y 1,10 A°) en los municipios de Amacuzac y Tequesquitengo respectivamente. Mientras solo dos muestras positivas al (SCMV) fueron detectadas en las localidades de Puente de Ixtla y Yautepec, pero con valores bajos de absorbancia respecto a los controles positivos The study was carried out in the months of June-July 2017, with the purpose of studying the current situation of the viruses associated with the cultivation of sorghum (Sorghum bicolor (L.) Moench). Twenty-one commercial sorghum plantation in Morelos state, were analyzed to detected Sugarcane yellow leaf virus (SCYLV) and Sugarcane mosaic virus (SCMV). The diagnosis was made, by means DAS-ELISA (double antibody) an immunoenzymatic test, that used a AGDIA kit (2017) and a reagent set of NANO Diagnostic (2017) "AC Diagnostic" with conjugated alkaline phosphatase, to detection of SCMV and SCYLV respectively. The results obtained evidenced, the presence of both viral diseases in the sorghum cultivation, in ten municipalities of Morelos state whit predominance of SCYLV. Positives samples to this virus with high absorbance (1.50 A° and 1.10 A°) on the municipalities of Amacuzac and Tequesquitengo, respectively were observed. While, only two positive samples of SCMV, in Puente de Ixtla and Yautepec were detected, but with low absorbance values respect to positive controls

Abstract

The production of fig (Ficus carica L.) in Mexico has become very important in recent years, due to the growing demand in the international market. The state of Morelos stands out as the main fig producer nationwide. The municipalities of Villa de Ayala, Tepalcingo and Axochiapan concentrate the highest productivity, however, serious affectations by some diseases such as rust caused by Cerotelium fici (Butler) Arthur have caused losses in crop yield. The objective of the work was to determine the incidence and severity of this disease, in two periods during the crop cycle. Representative samples with symptoms were taken in commercial plots of three municipalities in the state of Morelos. The incidence of the fungus and its severity were evaluated using a visual estimation scale, during February-March and August-October 2019. Six evaluations were made with weekly frequency during the cycle. The fungus was morphologically identified using taxonomic keys. The presence of C. fici uredospores was confirmed and it was determined that rust was present in both periods, with a higher incidence in the months of February and March (dry period). The municipalities of Villa de Ayala and Axochiapan, had the greatest affectations with 45 to 70 % severity. [ABSTRACT FROM AUTHOR]

Abstract

Strawberry production has increased in Mexico, due to its taste, nutrition and high economic income. In Morelos, the production is affected by the strawberry dry wilt, a frequent disease in this crop that causes significant losses above 50% the production. The objective of this work was to identify the causal agent of the strawberry drier, perform pathogenicity tests from the isolate and compare against an isolated strain already identified, evaluate inoculation methods and observe the damage to the roots for this purpose they were analyzed plants with typical symptoms of the disease from a commercial plot were analyzed from June 2018. The identification of the fungus was made by cultural and morphological characteristics and compared with a strain of Fusarium oxysporum from Celaya, Guanajuato. The results show that the causal agent of the strawberry drier in Morelos is Fusarium oxysporum. The pathogenicity tests showed the damage caused by this fungus in the crop and its direct involvement in the fresh and dry weight of the roots in the plants. The comparison between means did not detect significant differences in the method of inoculation and the strains evaluated. [ABSTRACT FROM AUTHOR]

Abstract

The distribution, incidence and severity damage caused by the dieback complex (Lasiodiplodia spp.) in Persian lime (Citrus latifolia) was determined in 46 orchards of six average years old, 25 trees per orchard in the municipalities of Amacuzac, Ayala, Coatlan del Rio, Cuautla, Jantetelco, Jonacatepec, Puente de Ixtla, Tepalcingo and Tlaltizapan of Zapata, Morelos State, Mexico. Incidence was evaluated according to the number of plants having symptoms of dieback. There were four levels of severity, where 0= healthy tree, 1= gum exudation, 2= cracking with exposure of internal tissue and 3= well-defined canker and branch dieback. Which were transformed to a percentage of means of a scale of three levels of severity, transforming to a percentage of infection using the Townsend and Heuberger equation. Data were analyzed trough the Kruskal Wallis test and Tukey (α=0.05) and p<0.0001 in incidence and severity. There was a high incidence of dieback on stems 78% of Persian lime trees. The incidence and severity of dieback of Persian trees on different orchards had a range of 31.8 to 100% and 30 to 100%, respectively. By the other hand, municipalities such as Amacuzac, Ayala, Coatlan del Rio and Tlaltizapan, had the lowest levels of incidence and severity of dieback. [ABSTRACT FROM AUTHOR]
