Abstract

Tomato is more prone to attack of several insect pests mainly due to its tenderness and softness as compared to other crops. The crop is devastated by an array of pests like jassids, aphids, tobacco caterpillar, flea beetles, leaf miners, spider mites, and fruit borers. Tomato fruit borer, Helicoverpa armigera is the most destructive insect pest resulting in considerable losses in quantity as well as the quality of tomato fruits to the extent of 50 to 80 per cent. A field experiment was conducted to evaluate the bio-efficacy of GPI 1316 (Novaluron 9.45% + Lambda-cyhalothrin 1.9% ZC) against tomato fruit borer, Helicoverpa armigera at College of Horticulture farm, Sirsi during Kharif, 2019 and 2020. The treatment includes T1-Novaluron 9.45% + Lambda-cyhalothrin 1.9% ZC @ 78g a.i./ha; T2- Novaluron 9.45% + Lambda-cyhalothrin 1.9% ZC @ 90g a.i./ha; T3- Novaluron 9.45% + Lambda-cyhalothrin 1.9% ZC @ 102 g a.i./ha; T4- Novaluron 10 % EC @ 75g a.i./ha; T5-Lambda-cyhalothrin 5% EC @ 15g a.i./ha and T6- Novaluron 5.25% + Indoxacarb 4.5% SC @ 85.32g a.i./ha, and T7-Untreated check. Results revealed that, the treatment Novaluron 9.45% + Lambda-cyhalothrin 1.9% ZC @ 90 g. a.i./ha was found to be most effective in reducing the population of Helicoverpa armigera (Hübner) and recorded higher fruit yield with maximum cost-benefit ratio.
