Botanical powders were evaluated for their grain protectant efficiency against Callosobruchus chinensis Linnaeus in stored black gram grain. Among the various botanical powders tested, neem leaf (Azadirachta indica A. Juss), garlic bulb (Allium sativum Linnaeus) and eucalyptus leaf (Eucalyptus globulus Labill) @ 2 per cent (w/w) recorded more than 32 per cent adult mortality, higher half-life values (> 56.97 days) and higher gross persistency (> 1999.48). Significantly lower number of adults were emerged (< 20.75) in these botanical powders during six months of storage period.
