Stinkbugs have shifted from secondary to major pests in cotton. The primary reason for this phenomena is the switch to transgenic cotton utilizing the insertion of Bacillus thuringiensis genes. Prior to this shift, insecticide applications were made to a cotton crop ranging from 10-18 times during the growing season utilizing synthetic pyrethroid and organophosphate insecticides for the control of various Lepidoptera species during boll development. These insecticides were also controlling stinkbugs and damage was minimal. Today, only 3-5 insecticide applications are made to a cotton crop for the control of various escaped Lepidoptera species which has allowed stinkbug populations to increase, especially when cotton is adjacent to peanuts. In this trial, we first wanted to test the efficacy and timing of various insecticides for controlling stinkbugs in cotton as well as observe stinkbug population movement from peanuts into cotton. This trial was initiated adjacent to peanuts with each treatment replication moving progressively further away from the peanuts. Treatments in this trial included Bidrin, Topsin M, Bidrin + Topsin M, and a control. Each treatment showed a reduction in stinkbug injury compared to the control. As a side treatment, we also wanted to determine if a fungicide treatment for the control of Fusarium sp. induced by stinkbug feeding, would reduce the amount of hardlock. Even though we did not see a reduction in hardlock, we did observe that Topsin M has some type of activity in reducing stinkbug injury in developing cotton bolls.
