Question 1
A pesticide applicator is concerned about spray drift during a herbicide application
near a sensitive crop. Which technique is most effective for minimizing drift while
still providing adequate coverage?
A. Increasing spray pressure to create finer droplets
B. Using the largest practical droplets that still provide effective coverage
C. Applying pesticides during strong winds
D. Reducing nozzle size to produce a fine mist
Correct Answer: B. Using the largest practical droplets that still provide
effective coverage
Rationale: Larger droplets are less likely to be carried away by wind currents and
therefore significantly reduce spray drift. Applicators should select the largest droplet
size that still achieves adequate target coverage. Fine droplets produced by high
pressure or small nozzles are more susceptible to drift and can damage neighboring
crops, water sources, and sensitive environments.
Question 2
A homeowner asks how to interpret a pesticide classified as having low toxicity.
Which response by the applicator is most appropriate?
A. It is completely harmless to humans and animals.
B. No protective equipment is needed during application.
C. It should still be used with caution.
D. It may be applied without reading the label.
Correct Answer: C. It should still be used with caution.
Rationale: Even pesticides classified as having low toxicity can pose risks if misused.
Applicators should always follow label instructions, wear recommended protective
equipment, and handle products responsibly. Low toxicity does not mean no toxicity.
The phrase "use with caution" accurately conveys the need for safe handling.

including fines that may reach approximately $1,000 depending on state and federal
regulations. Proper recordkeeping helps ensure accountability, regulatory compliance,
and environmental protection.
Question 4
How are low-hazard pesticides generally classified?
A. Restricted-use pesticides
B. Experimental pesticides
C. General-use pesticides
D. Emergency-use pesticides
Correct Answer: C. General-use pesticides

to harm human health or the environment.
