Spodoptera frugiperda Nucleopolyhedrovirus SfNPV003: Compatibility with agrochemicals and storage stability

A Colombian isolate of Spodoptera frugiperda nucleopolyhedrovirus SfNPV003 was formulated as a powder by microencapsulating it with a methacrylic acid polymer, which increased the photostability of the virus. In order to generate recommendations for the use of this biopesticide, the objective of thi...

In order to generate recommendations for the use of this biopesticide, the objective of this study was to establish in vitro compatibility with chemicals (insecticides and fungicides) and to determine the product stability during 15 months at 8 °C, 18 °C and 28 °C. The virus was compatible with eight chemicals tested, with an insecticidal activity greater than 80%. When the biopesticide was stored at 8 °C, 18 °C and 28 °C, the insecticidal activity and the content of contaminants were within acceptance limits established for each property. Results indicated that microencapsulated SfMNPV can be stored at temperatures below 28 °C, thus ensuring product quality for at least 17 months,enough time for its distribution and use. Con un aislamiento colombiano del nucleopoliedrovirus de Spodptera frugiperda SfNPV003 se desarrolló una formulación en polvo mediante un proceso de microencapsulación con un polímero del ácido metacrílico, el cual aumentó la fotoestabilidad del virus. Con el fin de generar las recomendaciones para el uso de este bioplaguicida, el objetivo de la presente investigación fue establecer la compatibilidad in vitro con los productos químicos (insecticidas y fungicidas) que se utilizan con mayor frecuencia en el cultivo de maíz y determinar la estabilidad del producto durante 15 meses de almacenamiento a 8, 18 y 28 °C. El virus fue compatible con ocho agroquímicos evaluados y presentó una actividad insecticida superior a 80%. Cuando el bioplaguicida fue almacenado a 8, 18 y 28 °C, la actividad insecticida y el contenido de contaminantes se mantuvieron dentro de los límites de aceptación establecidos para estos parámetros. Con base en los resultados obtenidos se recomendó el almacenamiento del bioplaguicida a base del SfNPV003 en temperaturas inferiores a 28 °C, lo que garantiza la calidad del producto durante mínimo 17 meses, tiempo adecuado para su distribución y uso.  2014-12-24 2019-08-09T19:30:02Z 2019-08-09T19:30:02Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistacta.agrosavia.co/index.php/revista/article/view/361 10.21930/rcta.vol15_num2_art:361 http://hdl.handle.net/20.500.12324/35157 spa http://revistacta.agrosavia.co/index.php/revista/article/view/361/351 application/pdf Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Ciencia y Tecnología Agropecuaria; Vol 15 No 2 (2014); 219-228 Ciencia y Tecnología Agropecuaria; Vol. 15 Núm. 2 (2014); 219-228 revista Corpoica Ciência e Tecnologia Agropecuária; v. 15 n. 2 (2014); 219-228 2500-5308 0122-8706 10.21930/rcta.vol15-num2
