Comment Deadline Approaches for EPA’s Policy on Nanoscale Materials in Pesticide Products

Comments on the U.S. Environmental Protection Agency’s (EPA) proposed policy on nanoscale materials in pesticide products are due August 17, 2011. EPA offers two approaches for obtaining the information EPA believes it needs concerning nanoscale materials in pesticide products. Under the first approach, EPA would use Section 6(a)(2) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to obtain information regarding what nanoscale material is present in a registered pesticide...
