Abstract
Efficacy of some seed protectants against pulse beetle Callosobruchus chinensis (L.) in stored mungbean variety MH 421 was evaluated under laboratory conditions in the Department of Entomology, CCSHAU, Hisar during October-December 2018. The result revealed that the neem leaf powder (30g/ kg) and neem oil (10 ml/ kg) were found most effective with maximum adult mortality (100 and 98.33%, respectively), lowest grain damage and weight loss (1.06 and 1.20%) and (0.75 and 0.81%, respectively), followed by mentha oil (2.5 ml/ kg) and lemongrass oil (2.5 ml/ kg). Turmeric powder resulted in only less adult mortality (48.33%) with maximum infestation and weight loss (14.66 and 4.13%, respectively).
