Ch.1: Federal Pesticide Regulations

2. Core definitions

• Pest — any organism that damages or harms desirable plants, animals (including people), products, or structures.
• Pesticide — any chemical intended to directly control pest populations or prevent/reduce pest damage.

3. FIFRA & the EPA

• FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) = the most significant federal pesticide law; governs manufacture, sale, and application.
• The EPA administers FIFRA — it makes sure manufacturers and applicators follow the rules (Congress writes the statute).

4. Registration

• The EPA registers uses, not just the product — it may approve one crop (apples) and decline another (grapes). A product registered for outdoor use may not be used indoors.
• Registration is a scientific, legal, and administrative review of manufacturer data covering: ingredients (active + other/inert), site/crop, amount/frequency/timing of use, and storage/disposal.
• Risk assessment weighs risks vs. benefits; a use is registered when benefits outweigh risks (never "zero risk" — all pesticides carry some risk).
• Assessments consider harm to people and nontarget plants/animals (incl. endangered species) and contamination of surface water or groundwater.
• Both federal AND state (tribal/territorial) registration are required before a product may be bought or used in a jurisdiction.
• Risk mitigation measures reduce risk and can be a condition of registration (e.g., PPE, rate limits, safe-handling steps, no application during bloom to protect pollinators).
• Labels function as risk-mitigation documents — their restrictions are legally binding.

5. Two major classifications

• Restricted Use Pesticide (RUP) — could cause unreasonable environmental harm or injury to people without added restrictions. Cannot be sold to or used by the public; requires a certified applicator or someone under direct supervision.
• General use (unclassified) — most products; federal law does not limit use to certified applicators (but a state may).

6. Other registration mechanisms

• Section 24(c) — Special Local Need (SLN): a state authorizes an additional use of an already-registered product within its borders.
• Section 18 — Emergency Exemption: allows a registered product to be used for an unregistered purpose for a set period when no pesticide is registered for the pest.
• Section 25(b) — Minimum-Risk: exempt from federal registration because all ingredients pose little/no risk. Must still follow health-claim rules and list all ingredients on the label. (Some states may still require registration.)

7. Certification & recertification

• To be certified: prove you can use RUPs properly, safely, and legally — verified by passing an exam (broad knowledge of correct pesticide use).
• Additional certification required for: most fumigants, predator-control devices with sodium cyanide or sodium fluoroacetate, and aerial application of RUPs.
• Private applicator — applies pesticides to produce an agricultural commodity on land they or their employer owns or rents.
• Commercial applicator — anyone who does not fit the private-applicator definition.
• EPA sets certification standards and program requirements; a certifying agency must have an EPA-approved certification plan.
• Recertification interval is set by the state/tribe/territory but never longer than 5 years (may be a test, credits, or both).

8. RUP recordkeeping — the acre thresholds

• Over 1/10 acre (or ANY size in a greenhouse or nursery) → 9 required elements.
• Same-day spot treatment UNDER 1/10 acre → 6 required elements; location entry marked as a spot application with a short description.
• Record within 14 days of application. Keep records 2 years.
• Customer copy within 30 days — required of all commercial applicators (agricultural and nonagricultural).
• No standard form — handwritten or computerized is fine.
• The 9 elements include the certified applicator's name and certification number, plus brand/product name, EPA reg. number, total amount, date, location, crop/site, and area size.
• Recordkeeping is also smart business: documents work for complaints/lawsuits, shows which treatments work, and guides future purchases.

9. Supervising noncertified applicators

• Competency — the practical knowledge, skills, experience, and judgment to apply RUPs without unreasonable adverse effects.
• Direct supervision — application made by a competent person under a certified applicator's instructions and control.
  • The supervisor need not be physically present if available when needed (detailed written/oral guidance + a way to be contacted).
• Minimum ages: certified applicator 18; noncertified applicator 18 — except the family-farm exception: a 16-year-old may apply under direct supervision of a private applicator who is an immediate family member.
  • Even under that exception, no fumigants, sodium cyanide, sodium fluoroacetate, or aerial RUP application.
• Supervisor duties for a RUP job: be certified in the applicable category (e.g., structural); ensure the noncertified applicator was trained on the equipment within the last 12 months (before the job); verify PPE is label-specified, clean, and in working order; and know the federal/state/local supervisory requirements, including any on the label.
• A label can bar noncertified use entirely — that prohibition holds even under direct supervision.
• Some jurisdictions disallow direct supervision → anyone using a RUP must be certified.

10. Training programs & records

• Noncertified applicators must complete pesticide safety training at least every 12 months.
• Qualified trainers: a currently certified RUP applicator; a designated trainer of certified applicators/handlers; or someone who completed an EPA-approved train-the-trainer program (for trainers of handlers).
• Training record must include: printed name and signature, date completed, trainer's name, and a description of the training. The supervising certified applicator must create/verify it before the RUP is used.

11. Tolerance, residue & food safety

• Residue — pesticide remaining on a crop after application.
• FQPA (Food Quality Protection Act): the EPA must ensure food-use pesticides meet stringent safety standards for people and animals that eat the food.
• Tolerance — the maximum residue allowed on a crop; it's the enforcement trigger. Residues above tolerance → commodity can be seized and not sold or used.
• Tolerance factors: toxicity of the pesticide and its breakdown products, application amount/frequency, residue remaining at market, and all routes of exposure (food + drinking water, lawns, pets…). The EPA weighs total possible exposure.
• Risk cup — pesticides with a similar mode of action share one tolerance set; the more uses a pesticide has, the greater the chance the tolerance is exceeded and some uses canceled.
• Preharvest interval (PHI / "days to harvest") — required wait between treatment and harvest; varies by pesticide and crop.
• Keep residues legal: use pesticides only when necessary, follow label directions, and calibrate equipment to apply the proper amount.

12. Worker Protection Standard (WPS)

• Purpose: reduce pesticide poisoning and injury among agricultural workers and handlers.
• Applies to: owners/operators of agricultural establishments (farms, forests, greenhouses, nurseries) and commercial businesses hired to apply pesticides or advise on crops there.
• Three goals: (1) inform workers/handlers about safety, (2) protect them from potential exposure, (3) mitigate exposures that occur.

13. Endangered Species Act

• A label may direct users to an EPA website for a bulletin with location-specific use limitations protecting federally listed species.
• Bulletin limitations can include: buffer set-backs, reduced application rates, timing restrictions, and outright prohibitions on use.
