EPA Pesticide Registration Reviews

EPA Registration Review

Search Information Requests

The Arizona Pest Management Center, in coordination with the Western IPM Center and the Arizona Specialty Crops Block Grant program, tracks EPA calls for open comments on pesticide registration review issues.

Since 2006, we have responded with pesticide use data and valuable input from stakeholders, submitting comments on pesticides of importance to agriculture in desert southwest, including Arizona, Nevada, New Mexico, Utah, Colorado, and Imperial and Riverside Counties, California. We also comment on pesticides impacting recreational turf, ornamentals, structural pest control, and public health pest management.

For more information, or for suggestions to improve this website, contact Dr. Al Fournier.
