Agronomy 317 Principles of Weed Science Bob Hartzler Herbicide Registration and Labels I. FIFRA (Fed. Insecticide, Fungicide and Rodenticide Act) A. Federal law responsible for regulating pesticides to insure safety to users, consumers and the environment B. Major amendments 1. 1972 – Responsibility to enforce taken away from USDA and given to the newly formed EPA 2. 1988 – Major change in laws, most pesticides registered prior to 1984 needed to undergo registration to make sure they met current standards 3. 1996 – Food Quality Protection Act (FPQA) altered approach to regulating pesticides used on food crops C. In most states, the department of agriculture (Iowa Department of Agriculture and Land Stewardship) is responsible for enforcing laws regarding pesticide use II. Pesticide labels A. Pesticide label is a legal document, using a pesticide in a manner inconsistent with the label B. Types of labels 1. Federal (Section 3) – the primary label that normally, but not always, is valid for all states. 2, 2EE - specifies changes in rates, timing, or other minor things. Provides a way for manufacturer’s to adjust the current label without having to ‘relabel’ all the existing product in the marketplace 3. Supplemental label – Specifies a new use for the product. When RR crops were introduced supplemental labels were issued to specify use of glyphosate on the resistant crops 4. Special Local Need 24(c) label: Provides mechanism to allow expedite labeling of an existing product for a problem which no existing product is available. Used with products that are already registered and tolerances are available 5. Section 18- Emergency label: Urgent, non-routine problem for which there is no effective registered pesticide or alternative control tactic. Problem must pose a significant economic or environmental threat. C. Safety information 1. Posted at front of label 2. Signal words (caution, warning, danger) a. Pertain to formulated product, not just the a.i. b. Not necessarily acute toxicity, several products have warning or danger due to risk to eye exposure c. Products with Danger signal word require statement of practical treatment and 1-800- number for physicians 3. Worker Protection Standard a. Developed to ensure that ag workers and pesticide handlers not put at risk from exposure to pesticides b. Label has a special section specifying WPS c. Employer responsible for implementing d. Pertains to farms, forests, greenhouses, and nurseries i. Exceptions: pastures, golf courses, vertebrate pests and others ii. Farmers and their families exempt from most, but not all, provisions e. Provisions i. Training
