Assessment of integrated shoot and fruit borer (Leucinodes orbonalis) management practices in brinjal field

Abstract

To formulate a realistic sustainable management module for brinjal shoot and fruit borer (Leucinodes orbonalis) a field experiment was carried out during kharif seasons of 2016-17 and 2017-18 in the farmers’ fields at Imalia and Kakraua villages of Datia district in Bundel Khand zone. The combination of three components i.e. pheromone trap, timely mechanical control and application of Carbosulfan 25 EC @ 1000ml/ha at 20 days interval after 20 days of planting (M5) was found most effective in reduction of shoot damage (76.59%) and fruit damage (81.44%) followed by M6 (6 times pesticide sprays), M4 (Trap + Two spray of insecticide), M3 (Sex pheromone Trap + M1), M1 (Sanitation + Mechanical removal of shoot and fruits), M2 (Only installation of trap). Highest mean yield of Brinjal per field was recorded in M5 (227.00 q/ha) which is 30.63 per cent more than untreated field followed by M6, M4, M3, M1 and M2. IPM combination M5 provided the highest gross returns (Rs. 181840/ha) and highest net return Rs. 135790/ha. The highest benefit cost ratio of 4.19 was obtained from M4 followed by M5, M2, M6, M3 and M1. However, benefit cost ratio was found in M5 is statistically on par with M2 and M6 similarly, another combination M6 statistically at par with M2.
