Evaluation of insecticide and pheromone trap efficacy for management of fruit borer (Helicoverpa armigera) in tomato

Taking into account importance of tomato cultivation in Chomu block of Jaipur district, an experiment was conducted to evaluate field efficacy of Indoxacarb 14.5 SC and pheromone trap. Per cent fruit infestation in farmer’s practice (T1) was 15.35 whereas only 2.74 per cent fruit infestation was documented in assessed treatment (T2). Larval population per plant was high (3.14) in T1 treatment and recorded significantly lower (0.57) in T2 treatment. Number of adult moth trapped per trap was 12.50 only. Average fruit yield in assessed treatment was 510q/ha and 530q/ha during year 2021 and 2022, respectively. Fruit yield of farmer’s practice was 450 q/ha for year 2021 and 460q/ha for 2022.Net return of assessed technology (Rs. 2, 80,550) was high for year 2021 as compared to farmer’s practice (Rs.2, 23,000). Similarly, for year 2022 net return of assessed technology was Rs. 3, 09,750 and Rs. 2, 44,000 of farmer’s practice. Both the year economic performance of assessed technology of superior to farmer’s practice In-case of benefit cost ratio, it was recorded 2.22 and 2.40 for assessed treatment during year 2021 and 2022, respectively. However, it was 1.98 and 2.13 for farmer’s practice during year 2021 and 2022, respectively.
