Increasing Mid-South problems with tobacco budworms, Heliothis virescens, developing resistance to pyrethroid and other classes of insecticides since 1986 illustrate the need to follow established Insecticide Resistance Management (IRM) Guidelines. A three phased approach to IRM (developed by researchers and extension entomologists) utilized in central Louisiana which emphasizes the logical use of different classes of insecticides based on pest spectrum diversity and intensity as well as physiological stage of the cotton crop is presented.
