Abstract

Potato virus Y (PVY) is the most important viral disease, having the highest economic impact on potato production worldwide including India. Green peach aphid, Myzus persicae is considered as the most efficient, cosmopolitan and commonly abundant aphid vector for PVY. The present study was conducted to know the effect of different crop labelled insecticides on aphid population and virus spread. The results revealed that thiamethoxam 25 WG was superior in reducing aphid population (3.67) which was followed by imidacloprid 17.8 SL (4.47). DAC-ELISA recorded lower spread of PVY in thiamethoxam 25 WG and imidacloprid 17.8 SL treated plots. Overall, the study revealed that insecticides were efficient in reducing aphid population, which are the vectors of this virus, but could not completely limit the virus spread in the field.
