LAWS LABEL COMPREHENSION ENVIRONMENTAL SAFETY AND
APPLICATION PROCEDURES 2025/2026 Q&A WITH CORRECT DETAILED
ANSWERS
1. Which federal agency regulates the use of pesticides in the United States?
A. FDA
B. USDA
C. EPA
D. OSHA
Correct answer: C. EPA
Rationale: The Environmental Protection Agency (EPA) registers and regulates pesticides under
the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
2. What is the primary purpose of pesticide labeling?
A. To provide marketing information
B. To guide safe and effective use
C. To offer warranty protection
D. To increase shelf life
Correct answer: B. To guide safe and effective use
Rationale: Pesticide labels provide legally binding instructions for application, safety
precautions, and environmental protection.
3. What is the definition of an “active ingredient” in a pesticide?
A. The solvent used to mix the product
B. The chemical that controls the target pest
C. The inert filler material
D. The fragrance added for scent
Correct answer: B. The chemical that controls the target pest
Rationale: Active ingredients are the chemicals in pesticides responsible for pest control; inert
ingredients serve other purposes.
4. Which of the following personal protective equipment (PPE) is essential when handling
concentrated pesticides?
A. Cotton gloves and T-shirt
B. Chemical-resistant gloves and goggles
C. Sneakers and shorts
,D. Sunglasses and a hat
Correct answer: B. Chemical-resistant gloves and goggles
Rationale: PPE is critical to prevent pesticide exposure; gloves and goggles protect skin and eyes
from harmful chemicals.
5. The signal word “Danger” on a pesticide label indicates:
A. Low toxicity
B. Moderate toxicity
C. High toxicity
D. No toxicity
Correct answer: C. High toxicity
Rationale: Signal words on labels indicate acute toxicity. “Danger” is used for highly toxic
pesticides.
6. Which type of pesticide targets fungal infections on plants?
A. Herbicide
B. Fungicide
C. Insecticide
D. Rodenticide
Correct answer: B. Fungicide
Rationale: Fungicides are specifically formulated to prevent or control fungal diseases in crops
and plants.
7. What is the first step in pesticide spill response?
A. Continue application as planned
B. Evacuate the area and prevent exposure
C. Dilute the spill with water
D. Record the spill for future reference
Correct answer: B. Evacuate the area and prevent exposure
Rationale: Immediate safety of humans and animals is the priority during a pesticide spill.
8. Which of the following is considered a mechanical method of pest control?
A. Insecticide spray
B. Hand-picking insects
C. Systemic herbicide
D. Biological predator release
Correct answer: B. Hand-picking insects
Rationale: Mechanical methods involve physical removal or exclusion of pests without
chemicals.
, 9. What is the primary goal of integrated pest management (IPM)?
A. Eliminate all pests
B. Reduce pest damage to acceptable levels
C. Use chemical control exclusively
D. Replace natural predators
Correct answer: B. Reduce pest damage to acceptable levels
Rationale: IPM combines multiple strategies—cultural, biological, mechanical, and chemical—to
manage pests sustainably.
10. When applying a pesticide, the term “drift” refers to:
A. Mixing chemicals incorrectly
B. Movement of pesticide off-target by wind
C. Pests escaping treated areas
D. Expiration of the product
Correct answer: B. Movement of pesticide off-target by wind
Rationale: Drift can cause environmental contamination and non-target damage; applicators
must minimize it.
11. Which environmental factor can increase pesticide degradation in soil?
A. Low microbial activity
B. High temperature and sunlight
C. Heavy clay content
D. Low soil moisture
Correct answer: B. High temperature and sunlight
Rationale: Heat and UV light accelerate breakdown of many pesticides through chemical
reactions and photodegradation.
12. Which type of pesticide is designed to control weeds?
A. Insecticide
B. Fungicide
C. Herbicide
D. Rodenticide
Correct answer: C. Herbicide
Rationale: Herbicides are formulated specifically to control unwanted plants and weeds.
13. What is the purpose of a pesticide Material Safety Data Sheet (MSDS) or Safety Data Sheet
(SDS)?
A. To provide pricing information
B. To give detailed safety, health, and first aid information
C. To advertise the product
