 ABSTRACT

Nine insecticides were evaluated on cowpea against pod borers (Maruca vitrata and Heliocverpa armigera) during kharif 2017 & 2018 and results revealed that flubendiamide  0.02% (0.16 larva/plant),  fipronil  0.01% (0.35 larva/plant)  and chlorantraniliprole 0.0056% (1.18 larva/plant)  were found highly effective insecticides  whereas, spinosad 0.009% (1.24 larva/plant), profenophos 0.05% (1.40 larva/plant), novaluron 0.01% (1.43 larva/plant) and emamectin benzoate 0.0025% (1.48 larva/plant) were found moderately effective insecticides against M. vitrata. Treatments of  chlorantraniliprole 0.0056% (0.19 larva/plant), flubendiamide  0.02% (0.27 larva/plant)  and fipronil  0.01% (0.30 larva/plant)   were found highly effective insecticides whereas, spinosad 0.009% (0.91 larva/plant), profenophos 0.05% (1.06 larva/plant), novaluron 0.01% (1.11 larva/plant) and  emamectin benzoate  0.0025% (1.11 larva/plant) were found moderately effective insecticides against H. armigera. Treatments of acephate 0.075% and thiamethoxam 0.005% were found least effective insecticides against pod borers.
