Efficacy and Economics of New Insecticides and Botanicals for Jassid Control in Mung Bean (Vigna radiata, L. Wilczek)

Backround: The present investigation was undertaken during the kharif 2021 season at the experimental farm of B.R.D.P.G. College, Deoria, UP to assess the efficacy of six insecticidal treatments against jassid populations and pod damage incidence. Pusa Vishal variety mung bean seeds were sown with a spacing of 30×15 cm in plots measuring 5 m in length and 3 m in width. Each block, replicated three times, had an interplot distance of 1.5 m.

Aims: The study evaluated the effectiveness of new insecticide molecules and botanicals on jassid infestation and pod damage in mung beans. Six insecticidal treatments were tested for their impact on jassid populations and their economics.

Study Design: Randomized Block Design (RBD)

Place and Duration of Study: Experimental research field of the Department of Entomology, B R D P G College Deoria during Kharif season 2021.

Results and Conclusion: Results indicated that all insecticidal treatments were significantly superior to the control. Acetamiprid 20 SP showed the highest efficacy against jassid populations, followed by betacyfluthrin + imidacloprid, imidacloprid, chlorantraniliprole, neem gold (2%), and neem oil (3%), enhancing crop yield. The highest cost-benefit ratio was recorded with Acetamiprid 20 SP (1:14.47), followed by imidacloprid 17.8 SL (1:5.36) and betacyfluthrin + imidacloprid (1:3.68). The cost of protection and yield is proportional to the benefits achieved.
