PESTICIDE APPLICATORS EXAM
QUESTIONS AND CORRECT
ANSWERS (VERIFIED ANSWERS)
PLUS RATIONALES 2025
1. What is the primary federal law governing pesticide use in
the United States?
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
This law regulates pesticide registration, distribution, and
use to protect human health and the environment.
2. Which signal word indicates the highest level of acute
toxicity on a pesticide label?
Danger
"Danger" signifies high toxicity and severe hazards.
,3. What is the recommended minimum distance when
applying pesticides near water bodies?
50 feet
To prevent contamination of water bodies, a buffer zone of
at least 50 feet is often recommended.
4. Which personal protective equipment (PPE) is required
when handling pesticides labeled as "corrosive"?
Chemical-resistant gloves and eye protection
Corrosive pesticides can cause severe burns, so gloves
and eye protection are essential.
5. How often must pesticide applicators calibrate their
equipment?
Regularly, according to the label and manufacturer
instructions
Proper calibration ensures accurate pesticide application
rates to avoid under- or over-application.
6. What is the best method to dispose of pesticide
containers?
Triple rinse and puncture before disposal according to state
regulations
Triple rinsing removes residue, and puncturing prevents
reuse, complying with environmental safety laws.
,7. Which type of pesticide formulation is typically least likely to
drift?
Granular
Granules are heavier and less prone to drifting compared
to liquids or powders.
8. What does the abbreviation "LD50" represent?
Lethal Dose for 50% of test animals
It measures acute toxicity by the dose killing half the test
population.
9. What information is NOT found on a pesticide label?
Price of the product
Labels contain usage instructions, hazards, and ingredients,
but not pricing.
10. When applying pesticides in windy conditions, what is
the maximum wind speed recommended?
10 mph
Higher wind speeds increase drift risk; applications above
10 mph are discouraged.
11. What is the main purpose of a pesticide Safety Data
Sheet (SDS)?
Provide detailed safety and handling information
, SDS includes hazard info, first aid, and emergency
procedures for safe pesticide use.
12. Which agency is responsible for enforcing pesticide
regulations in North Dakota?
North Dakota Department of Agriculture (NDDA)
NDDA oversees pesticide licensing and compliance in the
state.
13. Which soil condition can increase pesticide leaching
into groundwater?
Sandy soil
Sandy soils have larger pores, allowing pesticides to move
quickly downward.
14. Which pest is controlled by a miticide?
Mites
Miticides are specific pesticides targeting mite infestations.
15. What is "pesticide resistance"?
When pests survive exposure to a pesticide that previously
controlled them
Repeated use of the same pesticide can select for resistant
pest populations.
16. What is the main hazard of pesticide drift?
Damage to non-target plants and animals
