Insecticide and miticide modes of action
Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.
The key to preventing insecticide resistance is to rotate materials with different modes of action (MOA), not chemical classes. Some of the new materials coming on the market have the same MOA while others work in a completely different way. The problem has been finding out specific MOA’s so these new materials can be incorporated into a control program.
Dr. Ray Cloyd of the University of Illinois surveyed the available insecticides and miticides and developed the mode of action and pest activity chart (click here for pdf) to help growers develop pesticide rotations for their operations.
