EFFECTIVENESS OF SAFER MANAGEMENT TECHNIQUES AGAINST KEY INSECT PESTS OF TOMATO AND GARDEN PEA IN KUMOUN HIMALAYAS

摘要

Safer management tools against major insect pests of tomato and garden pea have been evaluated for the first time in Kumaon hills of North West Himalayas. In tomato, four releases of Trichogramma chilonis @ 50,000 insects/ha/release at an interval of10 days from flowering initiation stage against fruit borer, Helicoverpa armigera and in garden pea, BSKE (Batain (Chinaberry, Melia azedarach) Seed Kernel Extract) (10%) against pod borers, H. armigera and Lampides boeticus were found most promising. Planting a row of marigold after 10 rows of tomato, application of BSKE, azadirachtin (0.03%), HaNPV@250 LE/ha, Bacillus thuringiensis @ 1 kg/ha, endosulfan (0.07%) have also significantly reduced the major insect pests of tomato and garden pea over control.
