ABSTRACT
The Heliothine complex was controlled effectively four new insecticides Pirate (pyrrole), Proclaim (emamectrin benzoate), Tracer (spinosad), and Intrepid (RH-2485). However, the mixed population was best controlled and highest yields achieved by mixing the insecticides Pirate and Tracer with the pyrethroid Karate (lambda-cyhalothrin). The insecticide mixture utilized the lower rate of Pirate and a half rate of Tracer with the higher rate of Karate. Pirate and Tracer provide excellent control of pyrethroid resistant tobacco budworm, Heliothis virescens, and Karate probably improved the control of the bollworm, Heliocoverpa zea.
