Evaluation of Dipel ES in an Integrated Pest Management System on Cotton

Stanley J. Nemec, Lowell V. Larson


An Integrated Pest Management System (IPMS) was evaluated for control of cotton pests using Dipel ES and low rates of Phaser or Guthion to preserve beneficial arthropods. This system was compared against a traditional control program involving multiple applications of broad-spectrum insecticides. The trial was located in the Brazos Valley of central Texas where the traditional approach has become cost prohibitive due to increased insecticide resistance levels in the tobacco budworm, Heliothis virescens, and to the flaring of secondary pests such as aphids and spider mites. The Dipel IPMS resulted in a savings of $28.27/A in insecticide costs compared to the traditional practice field without sacrificing final yield.
