ABSTRACT

The Heliothine complex, comprised of the cotton bollworm, Helicoverpa zea (Boddie), and the tobacco budworm, Heliothis virecens (F.), was a major pest of cotton in Southeast Arkansas during 2002. The impact of the Heliothine complex as been lessened by the widespread usage of Bt cotton and the development of new chemistries of insecticides. Our trials addressed the effectiveness of new insecticide chemistries when compared with existing compounds. When applied alone, newer products such as Tracer, Denim, Steward, and S-1812 provided acceptable control of mixed populations of tobacco budworms and bollworms, and performance was enhanced with the addition of a pyrethroid insecticide.
