All the treatments were found significantly superior over control in reducing diamond back moth population. Imidacloprid (0.01%) was most effective as it reduced the maximum larval population at each observational interval during first and second spray with highest marketable yield (228.35 q/ha). Cartap hydrochloride (0.05%) caused 58.8 to 60.1% reduction in larval population within 14 days of first and second spray. The treatment beta-cyfluthrin (500 ml/ha) was found effective and economical and had maximum cost benefit ratio (1:20:02).
