Abstract

Among all biopesticides, the maximum spider population was noted in the plots treated with biomix 0.3% which was at par with LAMIT 0.6%, eucalyptus oil 0.2%, and karanj oil 0.5%. These were followed by verticilium lecanii 0.4%, beauveria bassiana 0.4%, NSKE 5%, neem oil 0.2%, dashparni ark 0.6% and metarhizium + beauveria bassiana 0.4%.
