Abstract

Pectinophora gossypiella gained resistance against Bt cotton throughout India. Number of insecticides was screened against this pest. During 2024, study was conducted by Punjab Agricultural University at six locations to evaluate the efficacy of green chemistry and other commonly used insecticides against pink bollworm and the safety to natural enemies. Among the treatments, spinetorum 11.7 SC @ 50 g ai ha-1 was found highly effective followed by emamectin benzoate 5 SG @ 9.5 g ai ha-1, cypermethrin 25 EC @ 50 g ai ha-1, profenophos 50 EC @ 625 g ai ha-1, chlorantraniliprole 18.5 SC @ 30 g ai ha-1 and chlorpyrifos 20 EC @ 250 g ai ha-1 against pink bollworm. Chlorantraniliprole 18.5 SC and spinetoram 11.7 SC recorded higher number of natural enemies as compared to other insecticides. The seed cotton yield was significantly higher in the spinetoram 11.7 SC (20.82 q ha-1) being at par with profenophos 50 EC (20.51 q ha-1) and emamectin benzoate 5 G (20.71 q ha-1).
