1. A pesticide label is considered a legal document primarily because it is:
A. A marketing brochure
B. Approved by a farm supply store
C. Enforced under federal and state law
D. Written by the applicator
Correct Answer: C — Enforced under federal and state law ✔
Rationale: The pesticide label is a legal document under FIFRA, meaning it must be
followed exactly as it carries the force of law.
2. What is the primary purpose of Integrated Pest Management (IPM)?
A. Eliminate all pests completely
B. Reduce pest populations to acceptable levels
C. Increase pesticide application frequency
D. Replace all non-chemical methods
Correct Answer: B — Reduce pest populations to acceptable levels ✔
Rationale: IPM focuses on economic thresholds and combines multiple control
methods to manage pests sustainably.
3. Which pesticide formulation is most likely to be inhaled as a hazard?
A. Granules (G)
, B. Wettable powder (WP)
C. Baits
D. Pellets
Correct Answer: B — Wettable powder (WP) ✔
Rationale: WP formulations create fine particles that can become airborne,
increasing inhalation risk.
4. The signal word “DANGER” on a pesticide label indicates:
A. Slight toxicity
B. Moderate toxicity
C. High toxicity and potential for acute effects
D. No hazard if used correctly
Correct Answer: C — High toxicity and potential for acute effects ✔
Rationale: “DANGER” signifies the most toxic pesticides, often including highly
corrosive or poisonous substances.
5. What is the most effective way to prevent pesticide drift?
A. Spray during high winds
B. Use smaller droplet sizes
C. Apply when wind speed is low
D. Increase application height
Correct Answer: C — Apply when wind speed is low ✔
Rationale: Low wind conditions reduce off-target movement (drift) of pesticides.
6. Which PPE is most critical when handling concentrated pesticides?
A. Cotton gloves
B. Chemical-resistant gloves
C. Leather boots
D. Baseball cap
Correct Answer: B — Chemical-resistant gloves ✔
Rationale: Chemical-resistant PPE protects against dermal exposure, the most
common route of pesticide poisoning.
, 7. The “restricted-entry interval (REI)” refers to:
A. Time allowed between pesticide purchases
B. Time before mixing pesticides
C. Time workers must wait before re-entering treated areas
D. Time between label revisions
Correct Answer: C — Time workers must wait before re-entering treated areas ✔
Rationale: REI ensures worker safety after pesticide application.
8. Which factor most affects pesticide effectiveness?
A. Brand of sprayer
B. Soil color
C. Target pest life stage
D. Applicator age
Correct Answer: C — Target pest life stage ✔
Rationale: Pests are most vulnerable at specific life stages, such as larvae or
nymphs.
9. What is the function of an adjuvant?
A. Kill pests directly
B. Improve pesticide performance
C. Replace pesticides
D. Neutralize pesticide toxicity
Correct Answer: B — Improve pesticide performance ✔
Rationale: Adjuvants enhance spreading, sticking, or penetration of pesticides.
10.A calibration check ensures:
A. Pesticide is stored correctly
B. Proper application rate is delivered
C. Labels are updated
D. Weather is monitored
Correct Answer: B — Proper application rate is delivered ✔
Rationale: Calibration ensures accurate dosage and uniform application.
