, Question 1
A certified applicator in Michigan is preparing to apply a restricted-use
pesticide (RUP) to a 40-acre corn field. The label specifies a 48-hour
restricted-entry interval (REI) and requires a 30-foot vegetative buffer strip
adjacent to a stream. Which of the following scenarios would constitute a
violation of the label requirements?
A. Applying the pesticide when wind speed is 12 mph, blowing away
from the stream.
B. Allowing a farmworker to enter the field 24 hours after application to
repair a broken irrigation pipe without PPE.
C. Using a closed mixing system to load the pesticide into the spray tank.
D. Storing the pesticide in a locked cabinet in the equipment shed, away
from food and feed.
Correct Answer: B - Allowing a farmworker to enter the field 24
hours after application to repair a broken irrigation pipe without
PPE.
RATIONALE
The REI is 48 hours; entry at 24 hours without PPE violates the label.
Wind speed and direction are acceptable if away from stream; closed
systems and locked storage are compliant. The other options are legal
and safe practices.
Question 2
An applicator is mixing a wettable powder (WP) and an emulsifiable
concentrate (EC) in the same tank. Which of the following mixing orders is
most appropriate to ensure proper dispersion and avoid compatibility issues?
A. Add the EC first, then the WP, followed by a compatibility agent.
B. Add the WP first, then the EC, followed by a compatibility agent.
C. Add half the water, then the WP, then the EC, then the remaining
water.

, D. Add a compatibility agent first, then the WP, then the EC, then the
remaining water.
Correct Answer: D - Add a compatibility agent first, then the WP,
then the EC, then the remaining water.
RATIONALE
When mixing multiple formulations, the standard order is: fill tank
half with water, add compatibility agent if needed, add WP, then EC,
then remaining water. This prevents clumping and ensures even
dispersion.
Question 3
A grower wants to manage soybean aphids using integrated pest management
(IPM). Which of the following actions best exemplifies the IPM principle of
'pest monitoring and threshold-based decision making'?
A. Applying a broad-spectrum insecticide every two weeks regardless of
aphid presence.
B. Introducing lady beetles and lacewings after aphids are detected at low
levels.
C. Scouting fields weekly and treating only when aphid populations
exceed the economic threshold of 250 aphids per plant.
D. Using a seed treatment insecticide at planting to prevent any aphid
infestation.
Correct Answer: C - Scouting fields weekly and treating only
when aphid populations exceed the economic threshold of 250
aphids per plant.
RATIONALE
IPM emphasizes monitoring and treating only when pest populations
reach economic thresholds. Weekly scouting and threshold-based
treatment is the core of IPM. Other options are calendar-based or
preventative without monitoring.

, Question 4
Which of the following statements accurately describes the difference between
a pesticide 'label' and 'labeling' under FIFRA?
A. The label is the written material attached to the container, while
labeling includes the label and all other accompanying information such
as SDS and brochures.
B. The label is the EPA-approved document, while labeling refers only to
the instructions printed on the container.
C. Labeling is the legal term for the label, while the label is the physical
paper.
D. The label includes only the brand name and active ingredients, while
labeling includes use directions.
Correct Answer: A - The label is the written material attached to
the container, while labeling includes the label and all other
accompanying information such as SDS and brochures.
RATIONALE
Under FIFRA, 'label' is the written, printed, or graphic matter on the
pesticide container, while 'labeling' includes the label and all other
accompanying materials (e.g., SDS, brochures). This distinction is
crucial for compliance.
Question 5
An applicator is calibrating a boom sprayer to apply 20 gallons per acre (GPA)
at a speed of 5 mph with a swath width of 20 feet. If the nozzle flow rate is 0.4
gallons per minute (GPM), what is the required nozzle spacing on the boom?
A. 20 inches
B. 30 inches
C. 40 inches
D. 50 inches
Correct Answer: C - 40 inches
