Resumen
Se estudió alternativas para el control del complejo denominado como manchado de grano en el cultivo de arroz y su efecto sobre el rendimiento de grano. En este trabajo se encontró incidencia de los hongos que atacan al grano. En condiciones de campo presentan una gran variabilidad de daños y formas de manifestación. Sin embargo en el presente trabajo se afianzo en informaciones colectadas en la aplicación de alternativas para el control y manejo de estos patógenos. El control con agroquímicos es el más utilizado, hasta la aplicación de alternativas de tipo biológicas, que inciden sobre la capacidad de inoculo de infección. La utilización de estas alternativas continúan siendo estudiadas, los resultados experimentales encontrados aún son poco precisos y en algunos casos escasos para interacciones específicas. Respuestas positivas se reportan en aplicaciones tempranas con alternativas biológicas, siendo la más común, el uso de antagónicos como Bacillus
y Tricoderma, los cuales inhiben la formación de los agentes causales del manchado en el cultivo de arroz.
I studied ways to control complex called as grain spot rice farming and its effect on grain yield. In this study incidence of fungi that attack the grain he was found. Under field conditions are extremely variable from damage and forms of manifestation. However in this work it was consolidated on information collected in the application of alternative control and management of these pathogens. Control with agrochemicals is the most widely used alternative to the application of biological type, which affect the ability of inoculum of infection. The use of these alternatives are still being examined, the experimental results are still vague and in some few cases for specific interactions. Positive responses were reported in early applications with biological alternatives, the most common use of antagonistic as Bacillus and Trichoderma, which inhibit the formation of the causal agents stained in rice cultivation.
