Abstract
An experiment was conducted in Rabi season during 2014-2015 study the relative efficacy of different among all the treatments lowest number of gram pod borer was recorded in Spinosad (2.85). The next followed treatment was Chlorpyriphos (3.40), which was also statistically at par with Quinolphos (3.69), Cypermethrin (3.95). Remaining treatments are Fipronil (4.45) and Indoxcarb (4.63) were statistically at par Malathion (5.25) was recorded as least effective within the chemical insecticides. A maximum net return was recorded in T5 Spinosad (17.45 q/ha), followed by T3 Chlorpyriphos (16.24 q/ha), T2 Quinolphos (15.35q/ha), T1 Cypermethrin (13.92 q/ha), T4 Fipronil (12.20 q/ha), T7 Indoxcarb (11.90 q/ha), T6 Malathion (9.26 q/ha) as compared to control T0 plane water (7.25q/h). When cost benefit ratio was worked out, interesting result was achieved. Among the treatment studied, the best and most economical treatment was T5 Spinosad (1:3.40), followed by T3 Chlorpyriphos (1:3.03), T2 Quinolphos (1:2.99), T1 Cypermethrin (1:2.71), T4 Fipronil (1:2.36), T7 Indoxcarb (1:2.30), T6 Malathion (1:1.81) as compared to control T0 plane water Control (1:1.46).
