Abstract:
The present study entitled, Evaluation of different insecticides against pink bollworm, Pectinophora gossypiella (Saunders) in Bt cotton under field condition during Kharif 2020. Observation were made on rosette flowe%, green boll damage%, larval population per 20 bolls, open boll damage%, locule damage% and yield (q/ha). The results of experiment revealed that, among the tested insecticide chlorantraniliprole 18.5 SC found effective in management of pink bollworm, recording lowest rosette flower (7.44%), green boll damage (8.78%), pink bollworm larvae (3.09/20 bolls). At harvest chlorantraniliprole 18.5 SC recording less open boll damage (7.26%) and locule damage (4.09%). For all the recorded observation spinetoram 11.7 SC and lambda cyhalothrin 5 EC were found at par with chlorantraniliprole 18.5 SC. Among tested insecticides chlorantraniliprole 18.5 SC produced highest yield of seed cotton (20.45 q/ha). Among different tested insecticides the highest ICBR i.e. 1:19.25 was observed in spinetoram 11.7 SC.
