Shaila. O and S. R. K Rao

Abstract

The LC50 of the insecticides viz., abamectin, emamectin benzoate, novaluron and lufenuron against S.litura was determined as 210.23, 102.12, 350.45 and 453.78 ppm, respectively, whereas the fungicides viz., mancozeb, chlorthalonil, and carbendazim recorded LC50 values of 97.0, 1.16 and 40.94 ppm respectively. The test insecticides were non toxic to A.flavus at LC50, field recommended and other concentrations, whereas fungicides were also non toxic to S.litura
