The laboratory experiment was conducted to assess the effect of newer insecticides on seed quality and management of pulse beetle (Callosobruchus chinensis L) during storage of green gram seeds cv. DGGV-2 at the Department of Seed Science and Technology, UAS, Dharwad during 2021-22. The study involved seed treatment with five newer insecticides at two concentrations stored in cloth bags under ambient conditions. The experiment results revealed that seed treated with emamectin benzoate 5 SG (4 ppm/kg of seed) was most effective in controlling insect infestation recording the highest adult mortality (87.75%), lowest seed damage (3.67%) and weight loss (1.10%) and was on par with spinetoram 11.7 SC at 4 ppm per kg of seed (87.25%, 5.00% and 1.65%, respectively) compared to untreated (29.25%, 23.67% and 10.65%, respectively) at the end of nine months. The study concluded that the green gram seeds treatment with emamectin benzoate 5 SG was found most effective against pulse beetle infestation along with other insecticide under study which were on par in maintaining seed quality parameters above Indian Minimum Seed Certification Standards for at least six months under ambient condition.
