Evaluation of newer insecticides against leaf eating caterpillar, Spodoptera litura (fab.) infesting capsicum under Polyhouse condition
AA Tompe, UB Hole, SA More, SR Kulkarni and MS Walase
The present investigation was conducted to evaluate bioefficacy of newer insecticides against leaf eating caterpillar, Spodoptera litura (Fab.) infesting capsicum under Polyhouse condition at Hi-Tech Floriculture and Vegetable Project, College of Agriculture, Pune during Kharif 2018-19. Studies indicated that all the insecticidal treatments were significantly superior over untreated control. The treatment with cyantraniliprole was observed to be the most promising for suppression of larval population by recording lowest number of 0.63 larvae per plant. This was followed by chlorantriniliprole and lufenuron; in which 0.80 and 1.09 larvae per plant were observed. The remaining treatments in order of efficacy were flubendiamide, lambda cyhalothrin, spinosad and indoxacarb; which recorded 1.34, 1.62, 1.97 and 3.22 larvae per plant, respectively, as compared to untreated control plot in which 6.69 larvae per plant were observed.
The efficacy of newer insecticides against S. litura in terms of per cent fruit damage revealed that cyantraniliprole was found to be effective treatment among all treatments which had recorded 11.35 per cent fruit damage per plant which was at par with chlorantriniliprole; which recorded 12.31 per cent fruit damage per plant. The next best treatments in order of efficacy were lufenuron, flubendiamide, labdacyhalothrin, spinosad and indoxacarb in which 14.15, 16.05, 18.00, 20.94 and 26.71 per cent fruit damage per plant, respectively, were reported. The untreated plot was recorded highest 35.01 per cent fruit damage per plant.
