1. Which of the following is the most important reason to read a pesticide label before
application?
A. To learn the price of the product
B. To understand proper use and safety precautions
C. To compare it with other pesticides
D. To see the brand logo
Answer: B
Rationale: The pesticide label provides legally binding instructions on proper use, application
rates, and safety measures, which are critical for protecting the applicator, public, and
environment.
2. Pesticides should be stored in:
A. The kitchen
B. A secure, dry, and well-ventilated area
C. Near flammable liquids
D. In unlocked cabinets
Answer: B
Rationale: Proper storage prevents accidents, contamination, and degradation of the pesticide
product.
3. The LD50 of a pesticide indicates:
A. The shelf life
B. The lethal dose for 50% of test animals
C. The recommended application rate
D. The environmental impact
Answer: B
Rationale: LD50 measures acute toxicity; lower LD50 values indicate higher toxicity.
4. Which PPE is essential when handling highly toxic pesticides?
A. Gloves and long sleeves only
B. Waterproof boots, chemical-resistant gloves, respirator, and protective clothing
C. Sunglasses
D. Regular work boots
,Answer: B
Rationale: Full personal protective equipment minimizes exposure to toxic chemicals.
5. Which signal word on a pesticide label indicates the highest acute toxicity?
A. Caution
B. Warning
C. Danger
D. Notice
Answer: C
Rationale: “Danger” denotes the most toxic pesticides, requiring strict handling precautions.
6. Drift of a pesticide can be reduced by:
A. Applying during high winds
B. Using low-pressure nozzles and proper droplet size
C. Increasing the application rate
D. Spraying near water
Answer: B
Rationale: Proper equipment and application techniques reduce off-target movement of
pesticides.
7. Which method is best for disposing of empty pesticide containers?
A. Burning them
B. Triple rinsing and following label instructions
C. Throwing them in the trash
D. Burying in soil
Answer: B
Rationale: Triple rinsing and following label instructions prevent environmental contamination
and meet legal requirements.
8. Pesticide labels are legally enforceable under which act?
A. Clean Air Act
B. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C. Endangered Species Act
D. Clean Water Act
Answer: B
Rationale: FIFRA requires pesticides to be registered and used according to label instructions.
9. What is the main purpose of a Material Safety Data Sheet (MSDS)?
A. To provide marketing information
B. To provide detailed safety, health, and first aid information
C. To indicate pesticide effectiveness
D. To list competing brands
,Answer: B
Rationale: MSDS contains chemical hazards, handling, and emergency response information for
workers.
10. A pesticide applied to soil before planting is called:
A. Pre-emergent
B. Post-emergent
C. Contact
D. Systemic
Answer: A
Rationale: Pre-emergent pesticides prevent weed seeds from germinating, applied before crop
emergence.
11. Which type of pesticide controls insects?
A. Herbicide
B. Fungicide
C. Insecticide
D. Rodenticide
Answer: C
Rationale: Insecticides specifically target insect pests.
12. Systemic pesticides are absorbed by the plant and:
A. Kill only surface pests
B. Move through plant tissues to control pests internally
C. Evaporate immediately after application
D. Do not require label instructions
Answer: B
Rationale: Systemic pesticides move within plant tissues, providing internal protection against
pests.
13. Which factor does NOT affect pesticide degradation?
A. Temperature
B. Humidity
C. Crop color
D. Sunlight
Answer: C
Rationale: Environmental conditions like temperature, moisture, and UV light influence
chemical breakdown; crop color does not.
14. Which is the best method for reducing pesticide runoff into water sources?
A. Applying during heavy rain
B. Establishing buffer zones near water bodies
, C. Spraying near the edge of streams
D. Using higher rates of pesticide
Answer: B
Rationale: Buffer zones and careful application reduce contamination of water bodies.
15. Which piece of equipment is critical for measuring pesticide accurately?
A. Garden hose
B. Measuring cup or calibrated tank
C. Shovel
D. Watering can
Answer: B
Rationale: Accurate measurement ensures proper application rates, reducing hazards and
increasing effectiveness.
16. A pesticide with a long residual effect:
A. Acts immediately but disappears quickly
B. Remains active for an extended period, providing longer pest control
C. Is safer for humans
D. Does not require proper PPE
Answer: B
Rationale: Long-residual pesticides continue to control pests over time, but may pose higher
exposure risks.
17. Which statement about pesticide resistance is TRUE?
A. It develops when pests are never exposed to pesticides
B. Repeated use of the same pesticide class can lead to resistance
C. All pests are naturally resistant
D. Resistance cannot be managed
Answer: B
Rationale: Pests can develop resistance through repeated exposure; rotating pesticide classes
helps manage it.
18. Which of the following best describes “contact pesticides”?
A. Pesticides absorbed into the pest’s body
B. Pesticides that kill pests only when directly contacted
C. Pesticides that prevent germination
D. Pesticides that control soil nematodes
Answer: B
Rationale: Contact pesticides affect only pests physically touched by the chemical.
