Hello USDA and OECA,

The Special Review and Reregistration Division (SRRD) of the Office of Pesticide Programs (OPP) is providing a draft of the 2,4-D RED for your review. The key findings of this document are summarized in the executive summary, the beginning of the document, and in the label table, attached separately.

Mitigation measures include:

• Revised label language for direct applications to water for aquatic weed control.
• Reduced turf rate from 2.0 lbs ae/acre per application to 1.5 lbs ae/acre per application.
• Revised spray drift language.
• Require water soluble packaging for wettable powder formulations.

Please address comments to me and Mark Seaton (703-306-0469) by COB June 3, 2005.
