A field trial was conducted to evaluate the scheduled sequential sprays of new insecticide molecules against pink bollworm Pectinophora gossypiella (Saunders) in cotton during 2018 to 2020 at Regional Agricultural research station, Nandyal. Mean of two years data revealed that erection of pheromone traps at 45 DAS and spray of Neem oil 1500ppm@ 5ml/liter of water, Chlorantraniliprole 18.5SC @ 0.3ml/liter of water followed by spray of Bifenthrin 10% EC @ 1ml/liter of water at weekly intervals after pink bollworm crossing ETL had recorded lowest green boll damage, open boll damage and lowest pink bollworm larvae per twenty green bolls with highest yield.
