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 3rd, 7th, and 14th 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).
