Rationale: Pesticides must be stored in their original containers with labels intact to prevent
accidental misuse and ensure safety.
2. What is the primary route of pesticide entry that can cause poisoning?
A. Ingestion
B. Absorption through skin
C. Inhalation
D. All of the above
Answer: D. All of the above

8. Drift occurs when:
A. Pesticides remain on the target
B. Pesticides move from the target area to non-target areas
C. Pesticides degrade in sunlight
D. Pesticides are absorbed by soil
Answer: B. Pesticides move from the target area to non-target areas
Rationale: Drift can cause damage to other crops, water sources, or humans and must be
minimized.
9. The most important factor in determining pesticide toxicity is:
A. Price
B. Route of entry and dose
C. Color
D. Application equipment
,Answer: B. Route of entry and dose
Rationale: Toxicity depends on how a pesticide enters the body and the amount exposed.
10. To prevent pesticide contamination of water, applicators should:
A. Spray directly over water bodies
B. Maintain buffer zones near water
C. Mix pesticides near streams for convenience
D. Apply during heavy rain
Answer: B. Maintain buffer zones near water
Rationale: Buffer zones reduce runoff or drift into sensitive water sources.
11. A systemic pesticide:
A. Kills pests only on contact
B. Moves within the plant to protect it
C. Evaporates quickly
D. Is never absorbed by plants
Answer: B. Moves within the plant to protect it
Rationale: Systemic pesticides are absorbed and distributed throughout the plant for ongoing
protection.
12. Which of the following is NOT required on a pesticide label?
A. EPA registration number
B. Signal word
C. Manufacturer’s phone number
D. Personal phone number of the applicator
Answer: D. Personal phone number of the applicator
Rationale: Labels must have manufacturer info and registration, but applicator phone numbers
are not required.
13. How should you dispose of empty pesticide containers?
A. Burn them
B. Triple-rinse and puncture before recycling or discarding
C. Throw in household trash without rinsing
D. Refill with other chemicals
Answer: B. Triple-rinse and puncture before recycling or discarding
Rationale: Proper disposal prevents contamination and accidental exposure.
14. Which of the following is a chronic effect of pesticide exposure?
A. Immediate nausea
B. Skin rash
C. Cancer or reproductive harm
D. Eye irritation
, Answer: C. Cancer or reproductive harm
Rationale: Chronic effects develop over long-term exposure, unlike acute effects which appear
immediately.
15. Which factor does NOT affect pesticide effectiveness?
A. Temperature
B. Humidity
C. Application timing
D. Applicator’s favorite color
Answer: D. Applicator’s favorite color
Rationale: Effectiveness depends on environmental conditions and timing, not personal
preferences.
16. The term IPM (Integrated Pest Management) means:
A. Using only chemical pesticides
B. Combining biological, cultural, and chemical methods
C. Ignoring pest populations
D. Spraying daily
Answer: B. Combining biological, cultural, and chemical methods
Rationale: IPM focuses on sustainable pest control using multiple strategies with minimal
environmental impact.
17. Which equipment requires calibration before application?
A. Hand sprayers
B. Boom sprayers
C. Airblast sprayers
D. All of the above
Answer: D. All of the above
Rationale: Proper calibration ensures correct pesticide dosage, avoiding under- or over-
application.

A. Wipe with a dry cloth
B. Wash immediately with plenty of water
C. Apply ointment
D. Wait
Answer: B. Wash immediately with plenty of water
Rationale: Immediate washing reduces absorption and prevents injury.
