Endothall Reregistration Eligibility Decision; Notice of Availability

This notice announces the availability of EPA's Reregistration Eligibility Decision (RED) for the pesticide endothall. The Agency's risk assessments and other related documents also are available in the endothall Docket. Endothall is used as an aquatic herbicide to control submerged aquatic vegetation and algae in lakes, ponds, and irrigation canals and is used as a desiccant on cotton, hops, potatoes, and seed production for alfalfa and clover. Endothall is also used as a biocide to control mollusks in cooling towers/systems. Endothall is applied as either a dipotassium salt or an N, N-dimethylalkylamine salt. The endothall acid is not directly applied to use sites; it is formed as a break-down product resulting from application of the salt forms. The amine salt is the only form applied terrestrially, while both the dipotassium and amine salt are applied to aquatic use sites. EPA has reviewed endothall through the public participation process that the Agency uses to involve the public in developing pesticide reregistration and tolerance reassessment decisions. Through these programs, EPA is ensuring that all pesticides meet current health and safety standards.
