This is EPA data, but the label is the law.

Everything below comes from the U.S. EPA pesticide registry. It is reference information for identifying a product — it is not the enforceable document. Application rates, approved sites, restrictions and personal-protective-equipment requirements must come from the product label that ships with the container you are holding, plus any state supplemental label that applies where you are working.
