Free Pesticide Core Exam Practice Test (25 Questions)

A mixed 25-question practice test covering all core competency areas. Pick an answer to see whether you're right and why. Aim for 70% or higher.

1. A label statement uses the word "should" (for example, "Applicators should avoid spraying near blooming plants"). This language is:

Answer: A. "Should" and "recommended" are advisory. Mandatory language uses words like "must," "shall," and "do not."

2. What does the EPA Registration Number on a label identify?

Answer: B. The EPA Reg. No. identifies the registered product. The EPA Establishment Number identifies the facility where it was produced.

3. For most pesticide handlers, the most common route of exposure is:

Answer: A. Skin contact is the most common way applicators and handlers are exposed, especially during mixing and loading.

4. If a pesticide gets in someone's eyes, first aid usually calls for rinsing the eye with clean running water for at least:

Answer: B. Hold the eye open and flush gently with clean water for at least 15 minutes, then get medical help, following the label's first aid statement.

5. Which conditions increase the chance of a pesticide leaching to groundwater?

Answer: B. Leaching is most likely with permeable soils, little organic matter, a shallow water table, and persistent, soluble, weakly adsorbed pesticides.

6. Pesticide drift is MOST likely to increase when:

Answer: A. Smaller droplets from high pressure or fine nozzles stay aloft longer and move off target more easily.

7. Integrated Pest Management (IPM) is best described as:

Answer: D. IPM uses identification, monitoring, thresholds, and a combination of cultural, biological, mechanical, and chemical tools.

8. An action threshold is:

Answer: B. Thresholds tie treatment decisions to pest numbers or damage levels, not the calendar.

9. A systemic pesticide:

Answer: A. Systemics are absorbed and translocated, so they reach pests that feed on treated tissue.

10. Which formulation abbreviation stands for emulsifiable concentrate?

Answer: C. EC (or E) is an emulsifiable concentrate: active ingredient in a petroleum solvent with emulsifiers, which forms a milky emulsion in water.

11. As spray nozzles wear, their output usually:

Answer: C. Worn nozzle orifices enlarge, increasing flow and distorting the pattern. Replace nozzles whose output is off by more than about 10% from a new nozzle's.

12. A flat-fan nozzle is commonly used for:

Answer: C. Flat-fan tips give a tapered pattern designed to overlap evenly on a boom for broadcast applications.

13. Spot treatment means:

Answer: D. Spot treatments target localized infestations, reducing cost and exposure.

14. To reduce drift during an application, you could:

Answer: B. Coarser droplets, lower release height, and appropriate weather all reduce off-target movement.

15. Pesticide tolerances (maximum legal residue levels on food) are set by:

Answer: C. The EPA sets tolerances. FDA and USDA monitor and enforce residue limits in food.

16. The Food Quality Protection Act of 1996 (FQPA) requires the EPA to consider:

Answer: B. FQPA raised the safety standard for food-use pesticides, including extra consideration for children and for aggregate and cumulative risk.

17. Under the 2017 federal certification rule, noncertified applicators using RUPs under direct supervision must be at least:

Answer: C. The federal rule sets a minimum age of 18 for noncertified applicators using RUPs under direct supervision.

18. Use-specific instructions given to a noncertified applicator should include:

Answer: D. The supervisor must give instructions specific to the product and site, including label directions and precautions.

19. When talking with a customer about a pesticide, a professional applicator should:

Answer: A. Honest risk communication builds trust. Claiming products are "safe" or "non-toxic" is misleading and may be prohibited.

20. If restricted-use pesticides are stolen, you should:

Answer: A. Theft should be reported promptly to law enforcement and the regulatory agency as required.

21. How many fluid ounces are in one U.S. gallon?

Answer: C. 1 gallon = 128 fluid ounces = 4 quarts = 8 pints.

22. A sprayer applies 20 gallons per acre. How many acres will a full 300-gallon tank cover?

Answer: D. 300 gal / 20 gal per acre = 15 acres.

23. Which statement must appear on essentially every pesticide label?

Answer: A. "Keep Out of Reach of Children" is a required precautionary statement on pesticide labels.

24. Which gloves are generally appropriate for handling liquid pesticides?

Answer: D. Leather and cotton absorb pesticides and can't be decontaminated. Use unlined chemical-resistant gloves as the label specifies.

25. To reduce risk to honey bees, an applicator should generally:

Answer: A. Bee-toxic products should not reach flowering plants while bees are active. Labels may carry specific pollinator protection language.
