IPM Handbook: Section II. Chemical Controlheadline bar Section II. Chemical Control (Download PDF version of this section)  **Important Notes**: New methods have been developed that reduce costs by more than 50 percent while maintaining effectiveness and reducing environmental impact.  See Reduced Agent and Area Treatments (RAATs) Brochure. Pesticide registrations change frequently.  As of 2004, Acephate is no longer registered while Dimilin is registered by EPA for rangeland grasshopper control.  II.1  Introduction to Chemical Control - R.
