pesticides in the United States?
A. Clean Water Act
B. Resource Conservation and Recovery Act
C. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
D. Toxic Substances Control Act
Rationale: FIFRA establishes the federal framework for pesticide
registration, labeling, and use to ensure human and environmental
safety.
2. What signal word on a pesticide label indicates the highest acute
toxicity?
A. Caution
B. Warning
C. Danger
D. Notice
Rationale: "Danger" is the signal word used for pesticides with high
acute toxicity, signaling extreme caution is required.
3. Which factor most affects the environmental movement of pesticides
after application?
A. Application cost
B. Soil type and rainfall
C. Brand of pesticide
, D. Worker clothing
Rationale: Soil composition and rainfall strongly influence pesticide
runoff, leaching, and persistence in the environment.
4. What is the main purpose of an integrated pest management (IPM)
program?
A. Eliminate all pests immediately
B. Reduce pest damage using multiple compatible strategies
C. Use only chemical pesticides
D. Maximize pesticide sales
Rationale: IPM aims to manage pest populations economically and
sustainably through monitoring, cultural, biological, and chemical
controls.
5. Which personal protective equipment (PPE) is required when handling
highly toxic pesticides?
A. Light cotton gloves
B. Safety glasses only
C. Chemical-resistant gloves, protective clothing, and respirators
D. Ear protection
Rationale: Highly toxic pesticides require PPE that protects skin, eyes,

C. A pesticide that can be used by the general public
D. A pesticide banned in Nevada

environment.
7. Which method is most effective for preventing pesticide resistance?
A. Increasing pesticide concentration
B. Applying the same product repeatedly
C. Rotating pesticides with different modes of action
D. Applying pesticides daily
Rationale: Rotating chemical classes reduces selection pressure on
pests and slows resistance development.
, 8. What is the primary route of pesticide exposure for most applicators?
A. Ingestion
B. Injection
C. Dermal contact
D. Hearing
Rationale: Skin contact is the most common route of pesticide
exposure during mixing, loading, and application.

interval (PHI)?
A. Time between purchase and application
B. Minimum time between pesticide application and crop harvest
C. Duration a worker can enter treated fields
D. Time pesticide remains effective in storage
Rationale: PHI ensures pesticide residues decline to safe levels before
crop consumption.
11. Which type of pesticide formulation is most easily absorbed
through the skin?
A. Granules
B. Dusts
C. Emulsifiable concentrates (EC)
D. Pellets
Rationale: Emulsifiable concentrates contain solvents that enhance
skin penetration, increasing dermal exposure risk.
12. When applying pesticides near a water body, what buffer
distance is recommended to reduce contamination?
A. 1 inch
B. 1 foot
C. Follow label-specified buffer zones
