Abstract:
Mustard aphid, Lipaphis erysimi (Kalt.) is a serious insect pest on cabbage. The field experiments were carried out to study the efficacy of insecticides against mustard aphid in cabbage. The efficacy of insecticides namely, cyantraniliprole; flonicamid; diafenthiruon, thiamethoxam, acetamiprid; imidacloprid; thiacloprid and dimethoate were evaluated against mustard aphid, Lipaphis erysimi under field conditions at ICAR-Indian Institute of Vegetable Research, Regional Research Station, Sargatia, Kushinagar, India. Over the untreated control, all insecticides were found to be more effective in reducing the aphid population. Diafenthiuron, flonicamid, and cyantraniliprole were found to significantly superior to other insecticides and untreated control in lowering the number of aphids at all the interval of observation giving 80.63, 79.79 and 78.58 percent reduction over control. The insecticides like imidacloprid, thiacloprid and acetamiprid were found relatively less effective causing 65.68, 66.70, 67.79 percent reduction over control. Therefore, we recommend the use of newer molecules cyantraniliprole and flonicamid as an alternative option for effective management of the mustard aphid, Lipaphis erysimi (Kalt.) in cabbage.
