In vivo and in vitro assessment of Trichoderma species and Bacillus thuringiensis integration to mitigate insect pests of brinjal (Solanum melongena L.)

In vivo and in vitro assessment of Trichoderma species and Bacillus thuringiensis integration to mitigate insect pests of brinjal (Solanum melongena L.)

Abstract The present study was performed to assess the individual and combined potential of 3 different concentrations of Trichoderma sp. (Ts) and Bacillus thuringiensis (Bt) to control brinjal insect pests. Tested formulations were applied on larval and adult stages of the pest. The Trichoderma lab...
