Abstract
Mustard aphid, Lipaphis erysimi Kaltenbach is a key pest of rapeseed-mustard and form the basis of crop loss from December to March. Field assessment was done to evaluate the bioefficacy of various doses of thiamethoxam over L. erysimi in mustard agroecosystem. Thiamethoxam 25%WG @ 25g a.i per ha was highly efficient against aphid with high grain yield, cost-effective. The results of former dose was on par with 37.5 g a.i per ha and 50 g a.i per ha after first and second spray with an interval of 10 days under open field environment with > 80% of decline in aphid populations. This was further followed by standard check dimethoate 30 % EC @ 200 g a.i per ha which was on par with thiamethoxam 25%WG@ 12.5 and 16.67 g a.i per ha. The control plot was least efficient and showed huge number of the mustard aphids. To manage the aphid population that reaches ETL, two applications with thiamethoxam 25 WG @ 25 g a.i. per ha at 10 days interval will be quite effective and provide good return.
