ABSTRACT

A field experiment was conducted on shoot borer, Leucinodes orbonalis during kharif 2002 under rainfed condition. The effectiveness of biorationals imposed three times at 30, 50 and 70 days after planting against shoot borer indicated that Nimbecidine @ 5 ml/l and NSKE @ 5 per cent were significantly superior in reducing the shoot infestation after each spray followed by spraying of pongamia oil @ 2 per cent and single application of neem cake @ 240 kg/ha. The significantly higher tuber yields were recorded in Nimbecidine @ 5 ml/l (35.82 q/ha) and NSKE @ 5 per cent (33.38 q/ha) with higher B: C ratios of 6.78 and 4.48, respectively which were followed by pongamia oil @ 2 per cent (30.91 q/ha) and neem cake applied once 240 kg/ha (28.07 q/ha)
