Abstract:
The investigations on evaluation of newer insecticides against major insect pests of brinjal were conducted on research farm of Department of Agricultural Entomology VNMKV, Parbhani during Kharif 2021-22. The work was carried out in Randomized Block Design with thrice replications. Eight insecticides treatments. At 7^th day after exposure of insecticidal spray indicated that the treatment Lambda cyhalothrin 9.5% ZC + Chlorantraniliprole 9.30% recorded lowest shoot infestation (1.20%). This was at par with Chlorantraniliprole 18.5 SC recorded (1.33%) and spinetoram 11.7% SC (1.51%). The lowest infestation by fruit borer was observed in Lambda cyhalothrin 9.5% ZC + Chlorantraniliprole 9.30% recorded (2.91, 2.67, 3.56% fruit infestation) and it was at par with chlorantraniliprole 18.5 SC (3.57, 3.31 and 2.59%). Highest fruit yield was observed in Lambda cyhalothrin 9.5% ZC + Chlorantraniliprole 9.30% (93.4 kg/ha), which is at par with chlorantraniliprole 18.5 SC (82.5 kg/ha) and Emamectin benzoate 5% SG (75.3 kg/ha) respectively.
