Efficacy of Plant Materials Against Callosobruchus Chinensis L., In Green Gram

The efficacy of some plant powders viz, tendril climber (Melothria perpussilla), black pepper (Piper nigram), lemon grass (Cymbopogon flexuosus), goat weed (Ageratum conyzoides), China berry (Melia azedarach), nirgundi (Vitex negundo), sweet basil (Ocimum basilicum), lantana (Lantana camara), Sweet flag (Acorus calamus) and Indian worm wood (Artemisia nilagirica) were evaluated @ 3 g/kg, 5 g/kg and 10 g/kg of green gram as post-harvest grain protectants against pulse beetle, Callosobruchus chinensis. Based on the parameters like fecundity, number of adults emerged, percentage of grain damage and percentage of weight loss, sweet flag was observed the most effective closely followed by black pepper while goat weed, lemon grass and tendril climber were least effective.
