EPA Conditionally Registers Pesticide Product Containing Nanosilver As a New Active Ingredient

The U.S. Environmental Protection Agency (EPA) announced on December 1, 2011, that it is conditionally registering a pesticide product containing nanosilver as a new active ingredient. HeiQ AGS-20 is a silver-based antimicrobial pesticide product approved for use as a preservative for textiles.  The final registration is not yet in the docket.  We believe, but cannot confirm, the final registration is largely similar to the draft proposed registration issued last year. As...
