Abstract

The effect of calotropis leaf extract at 5,10,15 per cent concentration on root penetration and at 10 and 15 per cent as soil and foliar application on population suppression of root knot nematode was studied under glass house condition. Maximum inhibition of penetration was observed on the first day itself at 15 per cent (0.6% penetration). When the leaf extract was applied as soil and foliar treatment at 10 and 15 per cent concentration, maximum shoot and root weight with more pods were observed in soil application at 15 per cent concentration followed by 10 per cent. Nematode population was minimum at 15 per cent soil application (88.5% and 72% reduction over control) followed by 10 per cent (87.1 and 79.3%) in root and soil application at 15 per cent.
