The present study entitled, “Efficacy of Different Insecticides against Green Semilooper Chrysodeixis acuta on Soybean” was undertaken incorporating nine treatments were evaluated for their efficacy against Green Semilooper on soybean. The experiment was laid out in RBD and was conducted during kharif season of 2013-14. The results were found to be statistically significant. However, numerically minimum cumulative average numbers of larvae of Green Semilooper were recorded treatment (T4) Profenophos 50EC @ 0.185% followed by the Treatment (T3) Profenophos 50EC @ 0.125%, (T6) Quinalphos25EC @ 0.075%, (T5) Quinalphos 25 EC @ 0.05%, (T2) Chlorpyriphos 20EC @ 0.06%, (T1) Chlorpyriphos 20 EC @ 0.04%, (T8) Triazophos 40 EC @ 0.06% and (T7) Triazophos 40 EC @ 0.04%. The treatment (T4) Profenophos 50EC @ 0.185% ranked first in recording maximum yield but, in treatment (T3) Profenophos 50EC @ 0.125% highest ICBR was recorded. The other treatments in descending order in respect of yield were of T3 > T6 > T5 > T2 > T1 > T8 > T7 and regarding ICBR T4 > T5 > T6 > T1 > T2 > T7 > T8. The overall picture on the basis of ICBR and yield of treatment, the treatment (T3) profenophos 50 EC @ 0.125 % and (T4) profenophos 50 EC @ 0.185 % shown promise in recording lower infestation of soyabean semilooper.
