Laboratory Measured Resistance and Field Control of Helicoverpa armigeraHub. by thiodicarb

T. Ramasubramanian and A. Regupathy

Abstract: Resistance to thiodicarb was diagnosed in the field population of Helicoverpa armigera from Tamil Nadu, India. Bouquet bioassay results in the laboratory indicated the level of resistance was 30.0 - 45.0% at recommended dose (1000g.a.i ha^-1) of thiodicarb. The suppression of larval population and reduction of damage to bolls, squares, locules and kapas in the field also in agreement with the laboratory results.
