The present field experiment was carried out to validate the existing IPM module of cotton under high density planting system (HDPS) using ARBC-64 (compact non-Bt variety) and Bindaas BG II (commercial Bt hybrid) at MARS, Dharwad, Karnataka, India during kharif 2016-17. Both genotypes were sown under HDPS (45 × 15 cm) and regular (normal) spacing (90 × 60 cm). IPM module comprised seed treatment with imidacloprid 600 FS, okra as a trap crop, installation of pheromone traps and need based application of selective insecticides. Results revealed that, irrespective of the genotypes, non-significant difference was observed with respect to pests population among HDPS and normal spaced crops. Further, HDPS blocks registered higher seed cotton yield of 26.12 and 23.95 q/ha as compared to 20.35 and 21.20 q/ha under normal spaced crop with a net profit of ₹ 90,485/- and ₹ 67,508/- per hectare under HDPS as compared to ₹ 68,215/- and ₹ 66,976/- per hectare, respectively.
