abstract
A field study was undertaken in Rabi 2017, at the Central Research Farm and dept. of horticulture farm, SHUATS Allahabad, with the objectives to assess the bio-efficacy and economics of bio-rational and bio-intensive IPM modules against shoot and fruit borer, and to analyze the insecticide residues in edible fruits of brinjal. Seven modules (3 Bio Rational, 1 Farmers Practice and 3 Bio intensive) were evaluated against shoot and fruit borer, (Leucinodes orbonalis). In experiment 1, Bio rational IPM Module T2 comprising of Seedling treatment with Chlorpyrifos, coriander as a border crop, and 1 spray each of Deltamethrin 1%+ Triazophos, Cyantraniliprole and Spinosad, at 30, 45 and 60 DAT was found to have least % shoot/fruit damage. Bio rational IPM Module T1 [BCR 1 : 3.89] (comprising of Seedling treatment with Chlorpyrifos and 1 spray each of Chlorantraniliprole, Spinetoram and Emamectin Benzoate at 30, 45 and 60 DAT) found most advantageous if produce was sold at equal price. In experiment 2, Bio intensive IPM Module T2 [BCR 1: 5.18] (Installations of pheromone trap, release of egg parasitoid Trichogramma chilonis, 2 spray Beauveria bassiana at 30 and 45 DAT, 1 spray of Azadirachtin at 60 DAT) was found effective and economic against the pest; it is also assessed best among all the modules if farmers get higher price of produce. All the modules were found safe from consumer’s point of view if fruits are harvested at 10 days after application of insecticides.
