Abstract

The efficacy of fenpropathrin 30 E.C. (Meothrin) was evaluated in four different concentrations (0.025%, 0.050%, 0.075% and 0.10%) along with imidacloprid 200 S.L. (Confidor) at 0.025%, and dimethoate 30 E.C. against the chilli aphid, Aphis gossypii (Glov.). Fenpropathrin 30 EC at 0.1% was most effective dose in reducing aphid population to 90% and gave maximum higher green chilli yield (95.16 q/ha) followed by fenpropathrin at 0.75% and imidacloprid at 0.025%. Dimethoate at 0.2% and fenpropathrin 0.025% proved less effective.
