Abstract:
The field experiment was carried out to evaluate of bio-efficacy of insecticides against thrips infesting chilli during kharif-rabi season of 2021-22 at Main Vegetable Research Station, AAU, Anand, Gujarat. Among the six tested insecticides, the maximum reduction in thrips population and increasing yield over control was found in the treatment of fipronil 80 WG followed by spinetoram 11.7 SC, cyantraniliprole 10.26 OD and thiamethoxam 25 WG with chilli yield of 118.39, 110.58, 105.72 and 87.72 q/ha, respectively. Looking to the ICBR, the highest (1:28.29) return was obtained with the treatment of fipronil 80 WG followed by thiamethoxam 25 WG (1:19.40) and lambda cyhalothrin 5 EC (1:17.55). Based on ranking, the treatments of fipronil 80 WG and thiamethoxam 25 WG found effective as well as economic against thrips infesting chilli.
