1. Which federal agency regulates the registration and use of pesticides
in the United States?
a) OSHA
b) FDA
c) EPA

for pesticide registration and regulation under the Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA).
,2. What is the primary purpose of a pesticide label?
a) To advertise the product
b) To provide legal instructions for safe and effective use
c) To display the chemical formula
d) To indicate price
Rationale: The label contains legally enforceable instructions for
proper handling, mixing, application, and safety precautions.
3. Which type of personal protective equipment (PPE) is most important
when handling concentrated pesticides?
a) Cotton gloves
b) Safety glasses only
c) Chemical-resistant gloves, goggles, and protective clothing
d) Regular clothing
Rationale: PPE must protect skin, eyes, and respiratory system from
toxic exposures, especially when handling concentrates.
4. What is the maximum allowable drift buffer for aerial application near
sensitive areas?
a) 5 feet
b) 25 feet
c) Varies by pesticide label and state regulations
d) 100 feet
Rationale: Buffer zones are specified on labels and may differ based
on chemical toxicity, formulation, and location.
,5. Which factor does NOT influence spray drift?
a) Wind speed
b) Droplet size
c) Temperature inversion
d) Aircraft color
Rationale: Aircraft color does not affect droplet drift; wind, droplet
size, and atmospheric conditions do.
6. What is the purpose of a pre-flight inspection before an aerial
pesticide application?
a) To fill fuel tanks
b) To schedule the pilot’s day
c) To ensure the aircraft and spraying equipment are safe and

applied in fine droplets?
a) Banding
b) Ultra-low volume (ULV) spraying
c) Soil injection
d) Granular application
Rationale: ULV spraying uses small quantities with fine droplets for
targeted aerial application.
10. Which atmospheric condition increases the risk of pesticide
drift?
a) Calm, cool mornings
b) Rainy days
c) Temperature inversions
d) Cloudy days
Rationale: Temperature inversions trap fine droplets in a stable air
layer, allowing them to drift horizontally.
