Incidence of mungbean yellow mosaic virus (mbymv), its epidemiology and management through mycotal, imidacloprid and tracer

Abstract

In the present study, four varieties of mungbean AARI-2006, Mung-97001, NM-2006 and M-6 were subjected to screening. Three chemicals, Imidacloprid, Mycotal and Tracer were evaluated against mungbean yellow mosaic virus (MBYMV) and whitefly. The variety AARI-2006 was resistant while the variety NM-2006 was moderately resistant. The chemical, Imidacloprid was most effective to control whitefly population and MBYMV. Correlation of environmental factors (maximum and minimum temperature, relative humidity and rainfall) with MBYMV percent plant infection was also determined. There was a significant correlation of environmental variables with MBYMV percent plant infection. The use of Imidacloprid proves to be a best option in case of epidemiological occurrence of environmental variables followed by Tracer and Mycotal respectively.
