Active ingredients will be considered for inclusion on this list by the following criteria:
1) The active ingredient is in at least one Environmental Protection Agency (EPA) registered pesticide, or is exempt under section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C.A § 136w(b)).
2) Pesticides containing this ingredient are labeled for unspecified food or herb crops.
