Section II. Chemical Control

Identifies available chemical insecticides, application methods, and rationale for selecting certain insecticides for grasshopper control. Since this chapter was written, new methods have been developed that reduce pesticide application rates, costs, and environmental concerns while retaining effectiveness (RAATs brochure).

Important Note: Since this chapter was written, new methods have been developed that reduce pesticide load in the environment while retaining cost effectiveness. See Management section. Pesticide registrations change frequently. As of 2004, Acephate is no longer registered, while Dimilin is registered for grasshopper control on rangeland.
