Abstract:
Seven different treatment modules were laid out in randomized block design (RBD) consisting of botanicals viz., Neem seed Extract 5%, Azadirachtin 10,000 ppm, Azadirachtin 300 ppm and bio-pesticides like HaNPV 250 LE/ha, Beauveria bassiana 1 x 10⁸ CFU, Metarhizium anisopliae 1 x 10⁸ CFU, Bacillus thuringiensis 1000 g/ha and Trichogramma chilonis @ 1.5 lakh/ha along with untreated control at days after planting (DAP) in each module for the management of H. armigera. The observations on tomato fruit borer infestation and it’s natural enemies were recorded after the initiation of fruit formation on the plant. The treatment module M5 (Application of Azadirachtin 10,000 ppm @ 3 ml/lit at 35 and 45 DAP, Application of HaNPV 250 LE at 55 DAP and Release of T. chilonis @ 1.5 lakh/ha at 65, 75 and 85 DAP) had shown the positive impact against tomato fruit borer. The treatment module M4 and M3 were found promising in minimizing the percent fruit infestation of tomato fruit borer. Similarly the treatment modules M5, M4 and M3 were found safer to natural enemies as well as proved to be promising in retaining the spider population.
