The stored food grain experiences major threat from insect pests. Among the storage pests, the pulse beetle is considered as one of the major and destructive pest. Infestation of pulse beetle causes both qualitative and quantitative loss in legume seeds. The present study was undertaken to evaluate the effect of botanicals in mung bean and come up with eco-friendly management strategies with botanicals against pulse beetle (Callosobruchus chinensis). The various botanical powders used were Neem, Tulasi, Notchi, Adhathoda, Bitter gourd, Black pepper, Turmeric, Ginger and Sweet flag are tested at the rate of 2g/ 100g seeds in a CRD with three replications. The results revealed that highest per cent mortality was recorded in Sweet flag at 72 HAT (31.66%) followed by Notchi (28.33%) whereas no mortality was recorded in control. Per cent grain damage was significantly lower in Sweet flag treated seeds (35.55%) followed by Notchi (42.22%) and the highest grain damage per cent was recorded in control (82.00%). The results obtained will definitely provide a better basis for improving the efficacy of botanicals like plant powders which could be effectively used as grain protectants and thereby reduce the load of toxic chemicals in our food stuff as well as in the environment.
