The site selected was uniform, cultivable with typical sandy loam soil having good drainage.The efficacy of chemical insecticides and bio-pesticides against brinjal shoot and fruit borer (Leucinodes orbonalis, Guenee). Frist spray per cent infestation of 3 DAS The data on the percent infestation of shoot and fruit borer on third day after first spray revealed that all the chemical treatments were significantly superior over control. Among all the treatments lowest percent shoot, infestation was recorded in Chlorantraniliprole (8.31%) followed by Spinetoram (9.53%) and Spinosad (11.25%). Treatments Sixer Plus (18.46%), Metarrhizium anisopliae (22.64%) were statistically at par with each other and treatments Beauveria bassiana (23.62%), Neem oil (24.99%) were found be least effective then on 7 DAS was among all the treatments lowest per cent shoot, infestation was recorded in Chlorantraniliprole (7.77%) followed by Spinetoram (9.57%) and Spinosad (10.17%). Treatments Sixer Plus (17.81%), Metarrhizium anisopliae (21.39%) were statistically at par with each other and treatments Neem oil (23.90%), Beauveria bassiana (23.92%) were found be least effective then on 14 DAS was found Among all the treatments lowest per cent shoot, infestation was recorded in Chlorantraniliprole (8.00%) followed by Spinetoram (9.96%) and Spinosad (12.16%). Treatments Sixer Plus (19.07%), Metarrhizium anisopliae (23.15%) were statistically at par with each other and treatments Beauveria bassiana (24.34%), Neem oil (25.94%) was found to be least effective. Then the Second spray: Per cent fruit infestation was revealed that on 3 DAS was among all the treatments lowest per cent shoot, infestation was recorded in Chlorantraniliprole (5.42%) followed by Spinetoram (8.27%) and Spinosad (9.12%). Treatments Sixer Plus (13.15%), Metarrhizium anisopliae (18.55%) were statistically at par with each other and treatments Beauveria bassiana (19.42%), Neem oil (20.64%) were found be least effective followed by on 7 DAS Among all the treatments lowest per cent shoot, infestation was recorded in Chlorantraniliprole (5.78%) followed by Spinetoram (8.62%) and Spinosad (9.24%). Treatments Sixer Plus (13.65%), Metarrhizium anisopliae (18.38%) were statistically at par with each other and treatments Beauveria bassiana (19.41%), Neem oil (20.14%) were found be least effective then on 14 DAS the data Among all the treatments lowest per cent shoot and fruit borer infestation was recorded in Chlorantraniliprole (6.27%) followed by Spinetoram (9.07%) and Spinosad (9.59%). Treatments Sixer Plus (14.07%), Metarrhizium anisopliae (19.12%) were statistically at par with each other and treatments Beauveria bassiana (20.64%), Neem oil (21.72%) but significantly superior over the control.
