Management of Pulse beetle, Callosobruchus chinensis Linn. using botanicals

Abstract

Under storage condition the botanicals like neem kernel powder (Azadirachta indica), and pongam oil (Pongamia glabra) were most effective and adhatoda leaf powder (Adhatoda vasica) was less effective against pulse beetle, Callosobruchus chinensis Linn. (Bruchidae; Coleoptera). The germinability of black gram seeds treated with tested botanicals and oils was comparatively less in adhatoda leaf powder and notchi leaf powder treatments when compared other with botanicals and oils tested. The germination percentage was high in neem kernel powder among the treatments. However a decreasing trend in the germination percentage was observed both in the botanicals and oils treated and untreated seeds.
