,Q1. A pesticide label states: 'Do not apply within 100 feet of any body of water.' The application site
is a corn field bordered by a 50-foot-wide vegetative buffer strip adjacent to a stream. Which action
best complies with the label while minimizing environmental impact?
A. Apply only if the wind is blowing away from the stream, maintaining a 100-foot no-spray zone
measured from the stream's edge.
B. Reduce the application rate by 50% to compensate for the buffer strip's width, then apply up to the
buffer edge.
C. Treat the buffer strip as part of the 100-foot setback, so the actual spray distance from the stream is
only 50 feet.
D. Apply using a drift-reducing nozzle and increase the buffer strip to 150 feet to ensure compliance.
Correct Answer: A. Apply only if the wind is blowing away from the stream, maintaining a 100-foot
no-spray zone measured from the stream's edge.
Rationale: The label restriction is a mandatory setback. The buffer strip does not reduce the required
distance; the 100-foot setback must be measured from the water's edge. Option A correctly measures from
the stream and uses wind direction to further reduce drift risk. Options B and C misinterpret the buffer as
a substitute for the setback. Option D adds an unnecessary extra buffer beyond the label requirement.
Why Wrong:
B - Reducing the application rate does not change the required setback distance; the label restriction
is absolute.
C - The buffer strip does not count toward the setback; the 100 feet must be measured from the
water's edge, not from the buffer's edge.
D - While drift-reducing nozzles are good practice, the label does not require exceeding the 100-foot
setback; this action is not mandated by the label.

Q2. An applicator notices that a pesticide application resulted in significant off-target damage to a
neighboring soybean field. Which factor is the LEAST likely contributor to this incident?
A. Temperature inversion at the time of application
B. Use of a coarse spray droplet spectrum
C. Application during wind speeds of 15 mph
D. Nozzle height set 4 feet above the target canopy
Correct Answer: B. Use of a coarse spray droplet spectrum
Rationale: Coarse droplets are less prone to drift than fine droplets. Thus, using coarse droplets reduces
off-target movement, making it the least likely contributor. Temperature inversions (A) trap droplets near
the ground, increasing drift potential. High wind speeds (C) and high nozzle height (D) both increase drift
distance.
Why Wrong:
A - Temperature inversions can cause unexpected lateral movement of spray droplets, increasing
off-target damage.
C - Wind speeds above 10 mph are generally associated with increased drift, and 15 mph is high
enough to carry droplets off-target.
D - Higher nozzle height increases the distance droplets travel in the air before reaching the target,
increasing drift potential.

, Q3. An applicator is calibrating a boom sprayer and finds that the output per nozzle is 0.5 gallons
per minute (gpm) and the nozzle spacing is 20 inches. The travel speed is 5 mph. What is the
application rate in gallons per acre (gpa)? (Use formula: GPA = (5940 × gpm per nozzle) / (mph ×
nozzle spacing in inches))
A. 29.7 gpa
B. 59.4 gpa
C. 74.25 gpa
D. 118.8 gpa
Correct Answer: A. 29.7 gpa
Rationale: Using the formula: GPA = (5940 × 0.5) / (5 × 20) = = 29.7 gpa. Option B results
from misplacing the decimal (using 594 instead of 5940). Option C uses 5940 × 0.5 / (5 × 8) incorrectly.
Option D uses 5940 × 0.5 / (5 × 5) incorrectly.
Why Wrong:
B - This would result from using 594 instead of 5940 in the formula.
C - This would result from using an incorrect nozzle spacing of 8 inches.
D - This would result from using an incorrect nozzle spacing of 5 inches.

Q4. A pesticide label indicates a pre-harvest interval (PHI) of 21 days. The crop is expected to be
ready for harvest on July 15. What is the latest date the pesticide can be applied to comply with the
label?
A. June 24
B. June 25
C. July 5
D. July 6
Correct Answer: A. June 24
Rationale: The PHI requires at least 21 days between application and harvest. Counting back from July
15, the last allowed application date is June 24 (21 days before July 15, excluding the harvest day).
Option B (June 25) would be 20 days before harvest, violating the PHI. Options C and D are far too late.
Why Wrong:
B - June 25 is only 20 days before July 15, which does not meet the 21-day PHI.
C - July 5 is only 10 days before harvest, violating the PHI.
D - July 6 is only 9 days before harvest, violating the PHI.
