Field evaluation of some new biorationals and bio-insecticides against Litchi bug, Tessaratoma javanica Thunberg at Dehradun

Abstract

We tested nine different insecticides including some biorationals and bio-insecticides, viz. Azadirachtin 1.0 %, Verticillium lecanii 01.15% WP, Emamectin Benzoate 5SG, Spinosad 45SC, Buprofezin 25.00% SC, Lufenuron 05.40% EC, Imidacloprid 70.00%, Chlorantraniliprole 18.50% SC, Lambda-cyhalothrin 05.00% EC against the litchi bug, Tessaratoma javanicai Thunberg. Chlorantraniliprole 18.50% SC, Imidacloprid 70.00% & Lambda-cyhalothrin 05.00% EC were recorded to check population buildup of litchi bug most efficiently and were at par in their action when compared together. Among other biorational insecticides and biopesticides Spinosad 45 SC and Buprofezin 25.00% SC were more effective and found superior to Azadirachtin 1.0 %, Verticillium lecanii 01.15% WP, Emamectin Benzoate 5SG and Lufenuron 05.40% EC.
