PESTICIDE REGULATION & AGENCIES
Question: What is the role of the EPA?
Answer: Regulates pesticides at the federal level under FIFRA.
Rationale: EPA ensures pesticides are registered, evaluated, and used safely nationwide.
Question: What is FIFRA?
Answer: Federal Insecticide, Fungicide, and Rodenticide Act.
Rationale: Requires pesticide registration and regulates labeling and use; modified by the Food
Quality Protection Act.
Question: Which Washington agencies regulate water use?
Answer: WSDA and Ecology.
Rationale: These agencies oversee pesticide use and water quality standards at the state level.
RESTRICTED USE PESTICIDES & WATER
Question: How are pesticides applied to water classified?
Answer: Restricted use pesticides.
Rationale: Aquatic applications pose higher environmental risk and require stricter controls.
Question: When are general use pesticides exempt from restricted designation?
Answer: When used only for specific closed systems (e.g., pools, aquariums, cooling towers).
Rationale: These uses do not discharge into natural waters.
, Question: Is pesticide application to surface water legal in WA?
Answer: No, unless permission is granted by Ecology.
Rationale: Protects surface water quality and aquatic life.
REQUIRED AGENCY CONTACTS

Rationale: Required to protect sensitive ecosystems.
Question: Why contact local or city planning agencies?
Answer: Some cities require additional permits.
Rationale: Local jurisdictions may impose stricter rules.
EFFECTS OF PESTICIDES ON AQUATIC LIFE
Question: How can misapplication harm non-target organisms?
Answer: Acute toxicity, habitat modification, altered oxygen levels, food disruption.
Rationale: Aquatic ecosystems are highly sensitive to chemical changes.
Question: Why is copper sulfate risky?
Answer: More toxic to trout; effectiveness decreases with water hardness.
Rationale: Species sensitivity and water chemistry affect toxicity.
Question: Which factors affect species response to pesticides?
