Q&A | Instant Download Pdf
1. What is the primary advantage of aerial pesticide application?
A) Lower chemical cost
B) Rapid treatment of large or inaccessible areas
C) Elimination of all drift risk
D) Requires no calibration
Aerial application is primarily used for speed and efficiency over
large or difficult terrain.
2. What is the most critical factor influencing spray drift?
A) Tank color
B) Wind speed and direction
C) Pilot experience only
D) Aircraft fuel type
, Wind is the dominant environmental factor affecting off-target
pesticide movement.
3. A temperature inversion is most likely to occur:
A) At midday
B) Just before sunrise
C) During strong winds
D) In heavy rain
Inversions form under calm, cool nighttime conditions trapping air
near the surface.
4. Which droplet size reduces drift most effectively?
A) Very fine
B) Fine
C) Coarse
D) Fog-like
Coarser droplets are heavier and less likely to drift off target.
5. What is the purpose of a pesticide label?
A) Marketing tool
B) Optional guidance
C) Legal instruction document
D) Aircraft maintenance guide
The label is a legal document that must be followed exactly.
6. Which organization regulates aerial application safety in flight
operations?
, A) EPA
B) FAA
C) USDA
D) OSHA only
The FAA regulates aviation operations including agricultural aircraft.
7. What is the main purpose of adjuvants in spray mixtures?
A) Increase aircraft speed
B) Improve pesticide performance
C) Replace pesticides
D) Reduce fuel use
Adjuvants enhance spreading, sticking, or penetration.
8. Drift reduction is BEST achieved by:
A) Increasing spray height
B) Lowering boom height and using coarse droplets
C) Flying faster
D) Using more water
Lower boom height reduces time droplets are exposed to wind.
9. What is a common aerial application aircraft type?
A) Submarine
B) Helicopter only
C) Fixed-wing airplane or helicopter
D) Hot air balloon
Both fixed-wing and rotary aircraft are used in aerial spraying.
