,Q1. A utility company plans to apply a soil-active herbicide along a right-of-way adjacent to a
wetland. The label prohibits application within 100 feet of surface water. Which of the following
actions best mitigates off-target movement while maintaining efficacy?
A. Apply a higher rate of a granular formulation to reduce drift
B. Use a low-volatile ester formulation and incorporate into soil
C. Select a water-soluble concentrate and apply via directed spray
D. Apply an amine formulation with a drift control adjuvant
Correct Answer: B. Use a low-volatile ester formulation and incorporate into soil
Rationale: Low-volatile ester formulations minimize vapor drift, and soil incorporation reduces runoff
and surface water contamination. Granular formulations (A) may still move via runoff. Water-soluble
concentrates (C) are more prone to leaching. Amine formulations (D) are less volatile but still require
drift control; incorporation is more effective for preventing off-target movement.
Why Wrong:
A - Granular formulations can still move via surface runoff and do not eliminate the need for buffer
zones.
C - Water-soluble concentrates are highly mobile in soil and may leach or runoff into water bodies.
D - Amine formulations with drift control reduce spray drift but do not address soil mobility or
runoff.

Q2. During a right-of-way inspection, you observe a dense patch of kudzu (Pueraria montana)
climbing over utility poles and into the canopy of adjacent trees. Which integrated pest management
approach would be most effective for long-term suppression?
A. Mow the patch monthly during the growing season for two years
B. Apply a foliar herbicide (e.g., triclopyr) in late summer, then re-treat resprouts annually
C. Introduce a biological control agent specific to kudzu
D. Apply a pre-emergent herbicide (e.g., pendimethalin) in early spring
Correct Answer: B. Apply a foliar herbicide (e.g., triclopyr) in late summer, then re-treat resprouts
annually
Rationale: Kudzu is a perennial vine with extensive root reserves; foliar herbicide application in late
summer (when carbohydrates move to roots) effectively kills the root system. Mowing alone (A) does not
deplete roots sufficiently. Biological control agents (C) are not widely available or effective for kudzu.
Pre-emergent herbicides (D) are ineffective against established kudzu.
Why Wrong:
A - Mowing only removes above-ground growth and does not kill the deep root system.
C - No effective biological control agent for kudzu is currently approved for use.
D - Pre-emergent herbicides only prevent seed germination, not control established perennials.

,Q3. A pesticide label states 'Do not apply more than 2 lb ai/A per season' for a product with 40%
active ingredient. You need to apply 1.5 lb ai/A per treatment. What is the maximum number of
applications you can make per season?
A. 1
B. 2
C. 3
D. 4
Correct Answer: A. 1
Rationale: Maximum seasonal rate is 2 lb ai/A. Each application delivers 1.5 lb ai/A. Two applications
would total 3 lb ai/A, exceeding the limit. Therefore, only one application is allowed.
Why Wrong:
B - Two applications would total 3 lb ai/A, exceeding the 2 lb ai/A seasonal limit.
C - Three applications would total 4.5 lb ai/A, far exceeding the limit.
D - Four applications would total 6 lb ai/A, far exceeding the limit.

Q4. A right-of-way manager wants to control woody brush with minimal impact on desirable
grasses. Which herbicide mode of action is most selective for broadleaf plants and least injurious to
grasses?
A. ALS inhibitor (e.g., metsulfuron)
B. Synthetic auxin (e.g., 2,4-D)
C. ACCase inhibitor (e.g., sethoxydim)
D. Photosystem II inhibitor (e.g., atrazine)
Correct Answer: B. Synthetic auxin (e.g., 2,4-D)
Rationale: Synthetic auxins like 2,4-D selectively control broadleaf plants by mimicking natural auxins,
causing uncontrolled growth, while grasses are generally tolerant. ALS inhibitors (A) can affect grasses
at higher rates. ACCase inhibitors (C) specifically control grasses, not broadleaf brush. Photosystem II
inhibitors (D) are non-selective and can harm grasses.
Why Wrong:
A - ALS inhibitors can injure grasses at rates used for brush control.
C - ACCase inhibitors are grass-specific, not effective on broadleaf brush.
D - Photosystem II inhibitors like atrazine are not selective for broadleaf brush over grasses.

, Q5. Which of the following describes the most appropriate use of a drift control adjuvant in a
right-of-way herbicide application?
A. To reduce spray droplet size for better canopy penetration
B. To increase droplet size and reduce the number of fine droplets
C. To lower the surface tension of the spray solution
D. To buffer the spray solution pH for improved herbicide stability
Correct Answer: B. To increase droplet size and reduce the number of fine droplets
Rationale: Drift control adjuvants increase the viscosity of the spray mixture, producing larger droplets
that are less likely to drift off-target. Reducing droplet size (A) increases drift. Lowering surface tension
(C) improves coverage but can increase fine droplets. Buffering pH (D) is a function of a water
conditioner, not a drift control agent.
Why Wrong:
A - Reducing droplet size increases the potential for drift, the opposite of drift control.
C - Lowering surface tension improves wetting but does not reduce drift; it may increase fine
droplets.
D - pH buffering does not affect droplet size distribution or drift potential.

Q6. A right-of-way applicator is required to keep records of pesticide applications. According to
Tennessee regulations, how long must these records be retained and what is the minimum
information they must contain?
A. 2 years; product name, amount applied, date, location, and pest targeted
B. 3 years; product name, EPA registration number, amount, date, and weather conditions
C. 5 years; product name, active ingredient, amount, date, and applicator certification number
D. 1 year; product name, rate, date, and method of application
Correct Answer: A. 2 years; product name, amount applied, date, location, and pest targeted
Rationale: Tennessee requires pesticide application records to be kept for 2 years, including product
name, amount applied, date, location, and target pest. EPA registration number (B) is not required;
weather conditions are not mandatory. Longer retention (C, D) is not required by state law.
Why Wrong:
B - EPA registration number is not required; weather conditions are optional.
C - 5 years is longer than the required 2-year retention period.
D - 1 year is insufficient; method of application is not a minimum requirement.

Q6. A right-of-way applicator is required to keep records of pesticide applications. According to
Tennessee regulations, how long must these records be retained and what is the minimum
information they must contain?
A. 2 years; product name, amount applied, date, location, and pest targeted
B. 3 years; product name, EPA registration number, amount, date, and weather conditions
C. 5 years; product name, active ingredient, amount, date, and applicator certification number
D. 1 year; product name, rate, date, and method of application
Correct Answer: A. 2 years; product name, amount applied, date, location, and pest targeted
Rationale: Tennessee requires pesticide application records to be kept for 2 years, including product
name, amount applied, date, location, and target pest. EPA registration number (B) is not required;
weather conditions are not mandatory. Longer retention (C, D) is not required by state law.
Why Wrong:
B - EPA registration number is not required; weather conditions are optional.
C - 5 years is longer than the required 2-year retention period.
D - 1 year is insufficient; method of application is not a minimum requirement.
