Bio-efficiency of some insecticides against Brinjal shoot and fruit borer, Leucinodes orbonalis (Guen.)

The studied data of shoot and fruit borer shows that, results were statistically superior over control in suppression of shoot damage caused by shoot borer. Lowest shoot infestation was recorded in treatment spinosad 0.01% (12.13%). The other effective treatments in minimizing the percentage damage of shoot borer were listed in descending order as emamectin benzoate 0.002% (15.05%) > cypermethrin 0.005% (17.19%) > imidacloprid 0.025% (21.95%) I > Metarrhizium anisopliae 1 lit/ha (23.16%) > B. Bassiana 1 lit/ha (24.88%) > Azadirachtin 2.5 ml ml/lit (24.88%) > mechanical shoot clipping (27.10%) respectively, these treatments were found superior over control (water spray) recording highest shoot infestation (36.60%) and for the fruit borer The next effective treatments in minimizing the percentage of fruit borer are listed in descending order as emamectin benzoate 0.002% (16.57%) > cypermethrin 0.005% (18.70%) > imidacloprid 0.025% (22.06%) > Metarrhizium anisopliae 1 lit/ha (23.91%) > B. Bassiana 1 lit/ha (%) (24.97%) > Azadirachtin 2.5 ml/lit (26.56%), > mechanical shoot clipping (29.48%) respectively, whereas in the treatment control (water spray) was recorded highest shoot infestation (37.15%).
