Georgia Category 34 – Aerial Methods
Exam Questions And Correct Answers
(Verified Answers) Plus Rationales
1. Which of the following best describes aerial application?
A. Applying pesticides using hand-held sprayers
B. Applying pesticides from an aircraft **
C. Applying pesticides with ground rigs only
D. Applying pesticides indoors
This is correct because aerial application specifically refers to the
delivery of pesticides using aircraft, such as planes or helicopters, to
cover large or hard-to-reach areas efficiently.
2. A primary advantage of aerial pesticide application is:
A. Low operational cost for small areas
B. Precision placement on individual plants
C. Ability to quickly cover large areas **
D. No need for calibration
Aerial application is efficient over large tracts of land, which makes
rapid coverage possible.
, 3. What is drift in relation to aerial pesticide application?
A. Fertilizer loss into soil
B. Movement of pesticide droplets off target **
C. Pesticide absorption into plant roots
D. Evaporation of spray from the aircraft
Drift refers to the movement of spray droplets away from the target
site, often caused by wind or improper application techniques.
4. Which factor has the greatest effect on spray drift during aerial
application?
A. Aircraft paint color
B. Wind speed and direction **
C. Type of pilot seat
D. Length of runway
Wind conditions are crucial because they influence how far droplets
can travel beyond the intended target.
5. One method to reduce drift during aerial application is to:
A. Fly lower to the canopy **
B. Fly higher above the canopy
C. Use only the smallest droplets
D. Increase aircraft speed
Lowering altitude when safe and appropriate reduces the time
droplets are exposed to wind, decreasing drift.
, 6. Which nozzle characteristic helps reduce drift by producing larger
droplets?
A. Fine spray tip
B. Drift-reducing nozzle design **
C. Nozzle without deflector
D. Blocked nozzle
Drift-reducing nozzles create larger droplets, which are less likely to
drift.
7. In aerial applications, a swath refers to:
A. A type of pesticide
B. The width of ground covered by a single pass **
C. A flight maneuver
D. A safety buffer zone
Swath width is the area covered between spray passes.
8. What is one major risk when applying pesticides by air over water
bodies?
A. Increased evaporation
B. Contamination of water and aquatic organisms **
C. Improved efficacy
D. Decreased aircraft performance
Pesticides reaching water can harm aquatic life and pollute sources of
drinking water.
, 9. The spray boom on an aerial application system is used to:
A. Lift the aircraft
B. Evenly distribute spray droplets **
C. Store fuel
D. Anchor the pilot
Spray booms hold nozzles and help deliver a uniform application
across the swath.
10. Why is calibration critical in aerial pesticide application?
A. It increases aircraft speed
B. It ensures that the correct amount of pesticide is applied **
C. It cleans the spray system
D. It guards against theft
Calibration ensures the labeled rate of pesticide is delivered for safety
and effectiveness.
11. The most important step before every aerial pesticide
application is to:
A. Check pilot licensing only
B. Review the pesticide label **
C. Fly around the target area
D. Eat a full meal
The pesticide label contains legal instructions on rates, targets, and
precautions, and must always be consulted.
