It can inferred (Moderately resistant genotype (Umran), deep summer ploughing after pruning plants, neem oil spray @ 5 ml per litre water October month, hand picking damaged adult November month spinosad 46 SC 0.4 December month) highly effective gave higher fruits. benefit-cost ratio tested systems decreased following order: (B: C 10.41:1)> 9.41:1)> 7.08:1)> 3.66:1).
