M. Ismail Chaudhry and Ghulam Ali Bajwa

ABSTRACT

Botanical pesticides are becoming more important for pest control due to hazardous effect of toxic chemicals. In the present study water extracts of different parts of four drug plants Azadirachata indica, Dhatoora alba, Melia azedarach and Calotropis procera were used to determine their efficacy against Plecoptera reflexa larvae, an important defoliator of shisham plantations. In case of A. indica and M. azedarach seed powder was used for making 10% water extract and for D. alba and C. procera leaves, branches and stem were boiled in water for making 15% and 21% decocations, respectively. The experiment was laid out in randomized complete block design. All test materials gave significant control over control with maximum by Dhatoora (90%) followed by neem (73.3%), Calotropis (66.7%), Bakian (60%) and control (13.3%).
