Abstract:
The field experiment on bioefficacy of insecticides against aphid on potato was carried out at Kodit Tal. Purandar, Dist. Pune (Maharashtra) in Rabi 2020-2021. The application of cyantraniliprole 10.26% OD @ 1.2 ml/litre of water found to be most effective against aphid and was at par with flonicamid 50% WG @ 0.3 g/ litre, imidacloprid 17.8% SL @ 0.3 ml/litre and thiamethoxam 25% WG @ 0.2 g/litre. No significant impact of any insecticidal treatment was observed on the predatory population of both coccinellid and chrysopid. The treatment of cyantraniliprole 10.26% OD recorded with higher yield of potato and maximum B:C ratio which was most effective and economical.
