COMPATIBILITY OF INSECTICIDE AND FUNGICIDE MIXTURES AGAINST SPODOPTERA LITURA (F.) ON VIRGINIA TOBACCO

Abstract

Evaluation of the efficacy and compatibility of certain new insecticides with fungicides alone and in combination as mixtures against Spodoptera litura (F.) on flue cured Virginia (FCV) tobacco was done. Results revealed that chlorfenapyr 10 SC @0.01% and chlorantraniliprole 18.5 SC @0.055% were the most effective. In combination with the fungicides too, chlorfenapyr 10 SC @0.01% was the best demonstrating compatibility. Among the two anthranilic diamides, chlorantraniliprole 18.5 SC @0.005% revealed compatibility with certain fungicides, whereas flubendiamide 48 SC @ 0.012% was observed with reduced efficacy in almost all combinations. Even though, with regard to the physical properties and pH all the combination treatments were stable even after two hours of preparation, their efficacy got slightly reduced except with chlorfenapyr 10 SC @0.01% and chlorantraniliprole 18.5 SC @0.005%.
