EXAM
1. Which Texas agency administers the state pesticide applicator licensing program?
A. Texas Commission on Environmental Quality
B. Texas Department of Agriculture
C. Texas Parks and Wildlife Department
D. Texas Department of State Health Services
Answer: B. Texas Department of Agriculture

certification, and enforcement in Texas.
2. What federal law regulates the registration and use of pesticides in the United States?
A. Clean Water Act
B. OSHA Act
C. FIFRA
D. Endangered Species Act
Answer: C. FIFRA
Rationale: The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) governs pesticide
registration, distribution, and use nationwide.
3. A pesticide classified for use only by certified applicators is called:
A. General Use Pesticide
B. Organic Pesticide
C. Restricted Use Pesticide
D. Experimental Pesticide
Answer: C. Restricted Use Pesticide
Rationale: Restricted Use Pesticides (RUPs) may only be applied by certified applicators or
those under their supervision due to higher risk.
4. The signal word “Danger” on a pesticide label indicates:
A. Slight toxicity
B. Moderate toxicity
C. High toxicity
D. Non-toxic product
Answer: C. High toxicity
Rationale: “Danger” indicates high acute toxicity and may include skull and crossbones.
,5. The primary purpose of a pesticide label is to:
A. Advertise the product
B. Provide mandatory legal instructions
C. Show company logo
D. List competitor products
Answer: B. Provide mandatory legal instructions
Rationale: The label is a legal document that provides required directions and restrictions for
safe use.
6. What does LD50 measure?
A. Long-term disease risk
B. Amount of pesticide drifting
C. Dose required to kill 50% of test animals
D. Label density
Answer: C. Dose required to kill 50% of test animals
Rationale: LD50 measures acute toxicity by indicating the lethal dose for 50% of a test
population.
7. Which PPE is most important when mixing concentrated pesticides?
A. Sandals
B. Gloves resistant to chemicals
C. Baseball cap
D. Cotton shorts
Answer: B. Gloves resistant to chemicals
Rationale: Chemical-resistant gloves protect hands from the most common route of exposure
during mixing.
8. Drift is most likely to occur when:
A. Wind speed is 3 mph
B. Wind speed is 10–15 mph
C. Humidity is high
D. Nozzle pressure is low
Answer: B. Wind speed is 10–15 mph
Rationale: Higher wind speeds increase the likelihood of pesticide drift.
9. What document contains detailed safety and emergency information about a pesticide?
A. Invoice
B. Warranty sheet
C. Safety Data Sheet
D. Sales receipt
,Answer: C. Safety Data Sheet
Rationale: The SDS provides hazard, first aid, and spill response information.
10. A private applicator in Texas primarily applies pesticides to:
A. Public highways
B. Neighbor’s property for hire
C. Agricultural land owned or leased
D. Golf courses
Answer: C. Agricultural land owned or leased
Rationale: Private applicators apply RUPs on property they own or control for agricultural
production.
11. The pre-harvest interval (PHI) refers to:
A. Time before planting
B. Time between application and harvest
C. Time before reentry
D. Mixing time
Answer: B. Time between application and harvest
Rationale: PHI ensures pesticide residues decline to legal limits before harvest.
12. Reentry interval (REI) is the:
A. Time before workers can reenter treated area
B. Time before irrigation
C. Time before livestock grazing
D. Spray duration
Answer: A. Time before workers can reenter treated area
Rationale: REI protects workers from exposure after application.
13. Which is a contact pesticide?
A. Systemic herbicide
B. Fumigant
C. Non-systemic insecticide
D. Growth regulator
Answer: C. Non-systemic insecticide
Rationale: Contact pesticides kill pests upon direct contact.
14. Calibration ensures:
A. Proper color of spray
B. Accurate pesticide application rate
C. Lower fuel cost
D. Faster spraying
, Answer: B. Accurate pesticide application rate
Rationale: Calibration confirms correct delivery rate per acre.
15. Which nozzle type reduces drift?
A. Hollow cone
B. Flat fan high pressure
C. Air induction
D. Fine mist
Answer: C. Air induction
Rationale: Air induction nozzles produce larger droplets that reduce drift.
16. Triple rinsing containers is required before:
A. Burning
B. Disposal or recycling
C. Storing indoors
D. Refilling with fuel
Answer: B. Disposal or recycling
Rationale: Triple rinsing removes residues before proper disposal.
17. Secondary containment is required for bulk storage to:
A. Increase sales
B. Prevent environmental contamination
C. Improve mixing
D. Reduce evaporation
Answer: B. Prevent environmental contamination
Rationale: Containment structures capture spills and leaks.
18. The Worker Protection Standard (WPS) protects:
A. Homeowners
B. Farmworkers and handlers
C. Retail clerks
D. Veterinarians
Answer: B. Farmworkers and handlers
Rationale: WPS safeguards agricultural workers from pesticide exposure.
19. Which application method is most targeted?
A. Broadcast spraying
B. Aerial application
C. Spot treatment
D. Chemigation
