Abstract

In a field experiment to evaluate the bioefficacy of different pesticides against castor leafhopper out dimethoate 30 EC showed 84.73% reduction in leafhopper population and was found most effective by giving yield of 40.50 q/ha followed by malathion 50 EC with 71.96% reduction in the leaf hopper population and 39.25 q/ha yield. Among the bio-pesticides, nimbecidine 1500 ppm proved most effective with a mean leafhopper population of 12.33 leafhopper/three leaves with a yield of 34.25 q/ha. Nimbecidine 300 ppm was the second best effective bio-pesticide and gave 35.40% reduction in the leaf hopper population and 32.75 q/ha yield.
