Abstract:
The present experiment was carried out to compare the efficacy against Leucinodes Orbonalis and its effect on the yield of Brinjal. The best and most economical treatment was Chlorantriniliprole @ 18.5 EC (1:10.2) which was on par with Emamectin benzoate @ 5 SG (1:9.8) followed by Carbosulfan 25 EC (1:7.3), Beauveria bassiana (1:6.4) Spinosad @ 45 % SC (1:5.5), followed by Bacillus thuringiensis (1:5.2) and, Neem oil (1:4.3) as compared to control (1:3.1). The data on the percent infestation of the shoot and fruit borer on brinjal 3^rd, 7^th, and 14^th day after the first spray reveal that all the chemical treatments were significantly superior over control. Chlorantriniliprole @ 18.5 EC (5.94) was par with Emamectin benzoate @ 5 SG (8.49) followed by Carbosulfan 25 EC (10.71), Beauveria bassiana (12.91) Spinosad @ 45 % SC (13.13), followed by Bacillus thuringiensis (14.85) and, Neem oil (16.87). The yields among the treatment were significant. The highest yield was recorded in Chlorantraniliprole @ 18.5 SC (207.50 q/ha), Emamectin benzoate @ 5 SG (183.83 q/ha), Carbosulfan 25 EC (137.9 q/ha), Beauveria bassiana (124.6 q/ha), Spinosad @ 45 % SC (106.5 q/ha), Bacillus thuringiensis (98.3 q/ha) and Neem oil (87 q/ha), as compared to control plot (56.6 q/ha).
