Abstract:

The field experiment on “Comparative efficacy of certain bio-pesticides against tomato fruit borer, Helicoverpa armigera (Hub.)” was conducted during 2014-15 at Central Research Farm and Department of Entomology SHIATS, Naini, Allahabad (U.P). The relative efficacy of biorational- insecticides viz., spinosad 45 SC (0.005%), quinalphos 25 EC (0.05%), HaNPV (350 LE/ha), Beauveria bassiana (0.3ml/lit), Verticillium lecanii (2.5kg/ha) and Metarhizium anisopliae (1000ml/ha) were evaluated against fruit borer (Helicoverpa armigera). The data on incremental percent reduction of different treatments revealed that the treatment Spinosad (74.97%), followed by quinalphos (66.31%), HaNPV (59.74%) >Beauveria bassiana (57.58%) > Verticillium lecanii (47.10%) > Metarhizium anisopliae (44.46%) found to be the most economically viable treatment. The highest cost benefit ratio was obtained from quinalphos (1:15.68) and the application of biorational- insecticides two spray at 15 days interval during rabi 2014-15.
