Abstract:

Surveillance of Mungbean Yellow Mosaic Virus (MYMV) on mungbean was undertaken to know the effect of weather factors on whitefly population (Bemisia tabaci Genn.) and MYMV incidence at three fixed locations viz., Kavalur, Raichur (UASR, Campus) and Wadagnal during kharif 2016. The results revealed that, the highest whitefly population observed during 26th SMW at Kavalur and 29th SMW at Raichur and Wadagnal locations during crop growth. The influence of weather parameters was studied by correlation and regression statistical analysis. The correlation analysis revealed that, maximum temperature was positively significantly correlated with whitefly population at Kavalur and Wadagnal villages (0.079 and 0.721 respectively) whereas minimum temperature was negatively correlated with whitefly population at Kavalur and Raichur (0.889 and 0.684 respectively). The per cent disease incidence showed negatively significant correlation with maximum temperature at Kavalur and Raichur (0.737 and 0.707 respectively). The rainfall was negatively correlated but non-significant with both whitefly population and per cent disease incidence at all the three locations. Correlation between whitefly population and disease incidence showed positive non-significant relation with each other in all the locations. The regression analysis revealed that, per cent contribution of weather factors on whitefly population and disease incidence at Kavalur, Raichur and Wadagnal was 98.3 percent (R2=0.983), 97.8 per cent (R2=0.978) and 97 per cent (R2=0.970) respectively.
