Field experiment for the evaluation of insecticides was conducted at the Agricultural Research Station, S D Agricultural University, Ladol during kharif 2018-2020. Results revealed that least fruit damage caused by Earias vitella F (9.84%) and Helicoverpa armigera Hubner (12.86%) was observed with emamectin benzoate 5SG at 0.0025%. Emamectin benzoate 5SG at 0.0025% gave maximum fruit yield and incremental cost benefit ratio. The pesticide residue analysis with emamectin benzoate 5SG at 0.0025% showed that the residues were below limit at 5 days after the spray. Also, only below MRL residue (0.223 ppm) of spinosad 45SC at 0.0169% was observed.
