A field experiment was carried out for the management of pink bollworm in Bt Cotton using different modules at IPM plot of 62F during kharif 2018 and 2019. All the modules worked significantly well in comparison with control module as chemical module was at the top in PBW management. As least number of PBW larvae (32.5/25 green bolls) and locule damage (71/100 fully opened bolls) were recorded in chemical control module. Biological control module (47 larvae/25 green bolls; 102 damaged locules/100 fully opened bolls) proved second best module following by biological + chemical control module (52.5 larvae/25 green bolls; 105.5 damaged locules/100 fully opened bolls). Highest population of P. gossypiella larvae (locule damage (130.5 damaged locules/100 fully opened bolls) and 67 /25green bolls) was seen in module remain untreated. While, for benefit cost ratio recorded in chemical control module was highest as compared to other modules. The present study finished that for management of P. gossypiella insecticidal sprays at ETLs proved better than biological control and other methods.
