Abstract
A field experiment was carried out to test the efficacy of biopesticides against the red two spotted spider mite Tetranychus urticae Koch infesting dodi (Jivanti), Leptadenia reticulata (Ret.) Wight and Aruott. The findings revealed that azadirachtin 0.15 EC was found most effective incidence (3.19/ cm2 leaf) followed by neemastra (3.27 mites/ cm2 leaf), neem oil (3.34 mites/ cm2 leaf) and neem seed kernal extract (3.42 mites/ cm2 leaf). Beauveria bassiana 5% WP (5.31 mites/ cm2 leaf), ashwagandha 7.5% leaf extract (5.37 mites/ cm2 leaf) and Metarhizium anisopliae 1.15% (5.53 mites/ cm2 leaf) were moderate in their effectiveness. Maximum incidence was noticed from the leaves treated with desi cow urine (5%).
