Georgia Category 34 – Aerial Methods Exam COMPLETE
QUESTIONS AND CORRECT ANSWERS LATEST UPDATE
THIS YEAR
Georgia Category 34 – Aerial Methods Exam
Georgia Category 34 Aerial Applicator Exam. Each question includes the answer and a summarized
rationale based on FAA Part 137, EPA/FIFRA regulations, UGA Extension Manuals, and aerial application
best practices.
1. Spray drift may be defined as?
A) Pesticide that lands perfectly on the target crop
B) Particles that move out of the target area and deposit on adjoining properties
C) Only the movement of visible fog
D) The intentional overspray of field margins
Answer: B
Rationale: Drift includes the movement of spray droplets, granules, or dust particles away from the
target site, potentially affecting adjoining properties .

2. The PRIMARY regulatory authority governing aerial pesticide applications in the United States is:
A) USDA
B) FAA and EPA (under FIFRA framework)
C) OSHA only
D) State aviation boards exclusively
Answer: B
Rationale: FAA regulates flight safety; EPA regulates pesticide use under FIFRA .
3. What two methods are considered excellent ways to manage spray drift?
A) Increase airspeed and use fewer nozzles
B) Control the spray droplet size and spray when the air is calm
C) Reduce tank pressure and fly higher
D) Add more surfactant and fly at dusk
Answer: B
Rationale: Larger droplets have greater mass and resist drift; calm air reduces lateral movement .

4. A droplet having a diameter of 50-100 micrometers is similar to:
A) Heavy rain
B) Mist
C) Garden hose spray
D) Fog
Answer: B
Rationale: Mist droplets fall in the 50–100 micron range; they are susceptible to drift .
5. A droplet having a diameter of 500 micrometers is similar to:
A) Light rain, medium agricultural sprays
B) Industrial smoke
C) Aerosol paint
D) Condensation
Answer: A
Rationale: 500 microns falls into the light rain category; these droplets are much less drift-prone .

6. Pesticide particles X and Y have diameters of 150 micrometers and 300 micrometers respectively. The
volume of particle Y is:
A) Twice that of X
B) Four times that of X
C) Eight times that of X
D) Equal to X
Answer: C
Rationale: Volume scales with the cube of the radius (diameter), so doubling the diameter increases
volume 8× (2³ = 8) .
7. The spray particles emitted by a nozzle are:
A) Uniform in size
B) A spectrum of different sizes (various sizes)
C) Invisible
D) Dependent only on pressure
