Abstract:
The present investigation was carried out during the Kharif season, 2017-18 at Student’s Instructional Farm, N.D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P) to study the efficacy of bio-insecticides and botanicals against brinjal shoot and fruit borer (Leucinodes orbonalis Guenee). The bio-insecticides and botanicals tested were: Emamectin benzoate 5 SG @ 75 g a.i/ha, Spinosad 45 SL @ 18 g a.i/ha, NSKE 5%, Karanj seed extract 5%, Onion extract 5%, Garlic extract 5%, Tobacco extract 5%, Cannabis (bhang) leaf extract 5%, Wood ash 10 g/ plant and compared with control. Results showed that Emamectin benzoate 5 SG (75 g a.i/ha) treated plots showed lowest infestation and gave higher fruit yield (313.85 q/ha) followed by Spinosad 45 SL (18 g a.i/ha) and NSKE (5%) which gave 300.58 and 284.33 q/ha fruit yield respectively. The least effective treatment was Wood ash (10 g/plant) and yielded only 225.14 q/ha healthy fruits. The maximum cost-benefit ratio was obtained from Emamectin benzoate 5 SG 75 g a.i/ha (1:21.23) treated plots. Tobacco leaf extract 5% treated plots though ecofriendly but gave least cost-benefit ratio (1:1.27). This study recommends the use of bio-insecticides and botanicals as they are significantly efficient in managing the brinjal shoot and fruit borer infestation.
