Efficacy of Synthetic Pyrethroids against Antigastra catalaunalis (Dup.) on Sesamum

The efficacy of synthetic pyrethroids on sesamum was evaluated. Results showed that the knockdown effect of pyrethroids was more than quinalphos against Antigastra catalaunalis (Dup.). Deltamethrin 12.5 g and cypermethrin 60 g persisted on the sesamum for 15 days followed by fenpropathrin 100 g and fluvalinate 75 g for 10 days and, fenvalerate 75 g and quinalphos 500 g a.i./ha for 7 days. Cypermethrin, deltamethrin, fenpropathrin and fluvalinate reduced the pod infestation efficiently. Fifteen days spray interval schedule was best compared to 10 and 20 days.
