Protection of shoot and fruit borer had higher over control 1 4 (92.5 and 91.3%, respectively) and fruit yield increment over control had higher (61.7%) in T. Among the all 4 characters control treatment produced lower results in this study. Use of neem leaf extract was highly effective to reduce the shoot and fruit infestation as well as to get higher yield.
