Title : Evaluation of bio-pesticides for the management of shoot and fruit borer Leucinodes orbonalis Guenee in brinjal vegetable

Abstract :

The On-farm field study were conducted in farmers field by Krishi Vigyan Kendra at Ramanathapuram village of Senthamangalam block, Namakkal districts to evaluate the bio-pesticides against brinjal shoot and fruit borer (BSFB) under field condition during rabi season 2020. In the treatment T2, seed treatment with Trichoderma viride (4g/kg) and Pseudomonas @ 10g/kg of seed; nursery + seedling dip treatment with Pseudomonas @ 10 g/ litre of water; soil application with neem cake @ 250 kg/ha; Maize as boarder crop against movement of whiteflies; installation of yellow sticky traps @ 20 numbers per hectare; sex pheromone traps @ 20 number per hectare and application of Neem oil formulations 10000 ppm @ one per cent were applied thrice at fifteen days interval starting from peak flowering stage significantly recorded lowest mean shoot infestation (5.78 per cent) of brinjal followed by T1 (6.39 per cent) and over control T3 (14.6 per cent), whereas fruit borer infestation recorded lowest in T2 (8.44%) followed by T1 (10.5 %) and over control T3 (20.9 %) . Maximum fruit yield was recorded in treatment T2 (236.2 q/ha.) was found to be superior over T1 (208.4 q/ha.) and T3 (175.6q./ha.), respectively. Wherein the lowest damaged fruit yield was recorded in T2 (23.6 q./ha) was superior than T1 (28.2 q./ha.) and T3 (32.8 q./ha.), respectively. With respect to gross and net income, T2 recorded highest income (Rs.354300 & Rs.249949) than T1 (Rs.312600 & Rs.201034) and T3 (Rs.263400 & Rs.157749) treatments. The benefit cost ratio of T2 (3.26) is superior over T1 (2.80) and T3 (2.49) treatments respectively.
