ARIZONA PESTICIDE APPLICATORS EXAM ACTUAL
PREP QUESTIONS AND WELL REVISED ANSWERS -
LATEST AND COMPLETE UPDATE WITH VERIFIED
SOLUTIONS — ASSURES PASS — PRACTICE
ASSESSMENT
1. Which of the following best describes the mode of action of
organophosphate insecticides? A. Disruption of chitin
synthesis
B. Inhibition of acetylcholinesterase enzyme
C. Blockage of sodium channels in nerve cells
D. Interference with mitochondrial respiration
Rationale: Organophosphates inhibit acetylcholinesterase, leading to
accumulation ofacetylcholine and overstimulation ofnerves.
2. A pesticide label indicates ”Use at 2 lbs per acre.” You have a 50-acre
field.
How much pesticide is required?
A. 50 lbs
B. 100 lbs
C. 25 lbs
D. 200 lbs
Rationale: 2 lbs/acre x 50 acres - 100 lbs total.
3. Which of the following is a key principle of integrated pest
management (IPM)?
,A. Use only chemical controls to save time
, B. Eradicate all pests regardless of threshold
C. Employ multiple control strategies based on pest monitoring
D. Spray preventively without pest identification
Rationale: IYM emphasizes monitoring, thresholds, and a combination of cultural,
biological, and chemical controls.
4. A pesticide applicator notices a spill of a liquid herbicide. What is the first
immediate action?
A. Continue applying to prevent waste
B. Sweep up the chemical and dispose in trash
C. Isolate the area and follow emergency procedures on the SDS
D. Rinse the area with water
Rationale: Safety protocols require isolating the spill area and consulting the
Safety Data Sheet fSDS) for proper cleanup.
5. Which factor most affects pesticide absorption through the skin?
A. Wind speed
B. Soil pH
C. Solvent type and concentration
D. Crop growth stage
Rationale: Solvent type and concentration influence dermal absorption of
chemicals.
, 6. The most effective way to reduce drift during aerial pesticide
application is:
A. Use a higher boom height
B. Apply during low wind and at proper droplet size
C. Increase nozzle pressure
D. Spray in early morning fog
Rationale: Drift reduction depends on droplet size, wind conditions, and proper
application technique.
7. Which of the following is a restricted-use pesticide (RUP)?
A. Bacillus thuringiensis (Bt)
B. Chlorpyrifos
C. Neem oil
D. Pyrethrin
Rationale: Chlorpyrifos is classified as a restricted-use pesticide due to toxicity and
environmental concerns.
8. When applying pesticides near a water body, which action is MOST
critical?
A. Spray faster to minimize time
B. Apply at night to avoid evaporation
C. Use higher pressure nozzles to reach farther
