Evaluate the efficacy of different insecticides against major insect pests of summer mungbean

The field experiment was conducted at the Breeder seed production farm, Department of Plant Breeding, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, during the summer season (2024). The summer mungbean seeds were grown in plots of 5 m × 5 m, with row-to-row spacing of 30 cm and plant-to-plant spacing of 10 cm. Ten treatments were evaluated against, whiteflies, jassids and thrips, i.e., Spiromesifen 22.9% SC, Pyriproxyfen 10.8% EC, Emamectin benzoate 5% SG, Chlorantraniliprole 18.5% SC, Chlorantraniliprole 8.8% + Thiamethoxam 17.5% SC, Lambda cyhalothrin 5% EC, Thiamethoxam 12.6% + Lambda cyhalothrin 9.5% ZC, Thiamethoxam 25% WG, Spinosad 45% SC and Control (Untreated) in RBD with three replications. The study revealed that the Thiamethoxam 25% WG was the most effective treatment for reducing the whitefly and jassid populations as well as the highest cost-benefit ratio was achieved. Additionally, Spinosad 45% SC was the most effective against thrips populations as well as the highest yield was observed.
