Imported Fire Ant; Approved Treatments

We are amending the imported fire ant regulations by adding the insecticide pyriproxyfen (Distance<SUP></SUP>) to the list of chemicals authorized for the treatment of containerized nursery plants and field-grown woody ornamentals that are to be certified for interstate movement from quarantined areas. This action will give the regulated community another choice with which to meet certification requirements. We are also updating the imported fire ant regulations by amending dosages and formulations for currently authorized insecticides in order to be consistent with product labeling and availability; by alphabetizing, for organizational purposes, the list of authorized chemicals; and by adding a brand name to the list of authorized chemicals, for consistency.
