- Abstract
Chilli crop is attacked by several insect-pests, among which fruit borer, Helicoverpa armigera (Hübner) is the major one. This work reports results of investigations carried out at farmer's field near PAU Regional Research Station Gurdaspur during kharif 2019 to determine bioefficacy of chlorantraniliprole (Coragen 18.5 SC) and spinosad (Tracer 45 SC), each applied @ 100, 125 and 150 mL ha-1 against the chilli fruit borer. All the treatments significantly reduced the larval population by 67.50 to 89.25 and fruit infestation by 72.09 to 90.70 per cent due to the fruit borer over the untreated control. The maximum fruit yield (192.85 q ha-1) was achieved with the highest dose of chlorantraniliprole, which was at par with the highest dose of spinosad (189.80 q ha-1). All the treatments did not show any significant adverse effect on population of natural enemies of chilli fruit borer and were non-phytotoxic to the crop.
