Abstract

Field trials were conducted at the Agricultural College and Research Institute, Madurai, Tamil Nadu in black gram with pre-harvest treatment of botanicals its to evaluate on the carry over of pulse beetle Callosobruchus chinensis (L.). It was observed that the application of Vitex leaf extract 10%, Pongamia oil 2% and Madhuca oil 2% had reduced the incidence. The same treatments in storage revealed that maximum protection was obtained with neem oil 1%, NSK powder 1% and neem leaf powder 2% followed by Madhuca longifolia oil 1%, Vitex negundo leaf powder 2% and Pongamia glabra oil 1% as grain treatments as revealed by reduced oviposition, adult emergence and damage.
