Category C6 Right-of-Way Pest Control Exam
ACTUAL QUESTIONS AND ANSWERS LATEST
UPDATE THIS YEAR
ACTUAL EXAM COVERAGE (SUMMARIZED POINT FORM) – TENNESSEE CATEGORY C6: RIGHT-OF-WAY
PEST CONTROL
The Tennessee Department of Agriculture (TDA) requires applicators to demonstrate competency in the
areas outlined below. The exam is based on the Category 6 training manual and federal/state pesticide
laws.
1. LEGAL & REGULATORY FRAMEWORK
• FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act): Requires certification for
restricted-use pesticide (RUP) purchase/use; civil penalties up to $5,000/violation, criminal
penalties $25,000/1 year in prison.
• Tennessee Rules & Regulations (Chapter 0080-09-02): Defines C06 scope and testing
requirements (minimum age 16 for commercial certification; certain activities prohibited under
age 18).
• Worker Protection Standard (WPS): Display application information, train workers/handlers,
provide decontamination sites, comply with Restricted-Entry Intervals (REIs), notify workers, and
require appropriate PPE.
• Recordkeeping: Commercial applicators must keep records of general and restricted-use
pesticides for at least 2 years.
• Endangered Species Act (ESA): Label restrictions to protect listed species and their habitats.
2. CHARACTERISTICS OF RIGHTS-OF-WAY (ROW)
• Definition: Areas used for common transport—public roads, highways, electric power lines,
pipelines, railways, industrial sites, transmission lines, drainage ditches, airports, irrigation
waterways, and public paths/trails.
• Why Vegetation is Managed: Safety, access to facilities, decreased maintenance costs,
reliability, aesthetics, wildlife, environmental protection, fire prevention, visibility, erosion
control, and prevention of weed spread to adjacent lands.
• Site Variation: ROWs are long and narrow, passing through various soils, topography, and
sensitive sites—no one-size-fits-all solution.
3. PEST IDENTIFICATION & BIOLOGY
• Weed Life Cycles:
o Annuals: Complete life cycle in one year (summer vs. winter annuals).
o Biennials: Two years to complete cycle (rosette first year, bolt, flower, seed second
year).
o Perennials: Live more than two years (simple, creeping, bulbous).
o Woody plants: Trees, shrubs, vines.
• Reproduction & Spread: Sexual (seed) and asexual (rhizomes, taproots, creeping roots, root
sprouts).
• Seed Dormancy: Allows seeds to survive unfavorable conditions and germinate later.
• Noxious Weeds: Legally designated plants that require mandatory control.
, Page 2 of 194
4. INTEGRATED PEST MANAGEMENT (IPM) & CONTROL METHODS
• IPM Definition: Use of all available tactics to manage pests so that acceptable control can be
achieved while minimizing economic, health, and environmental risks.
• Control Categories:
o Biological: Enhance natural enemies (predators, parasites, pathogens).
o Cultural: Create optimal growing conditions for desirable vegetation or unfavorable
conditions for pests (e.g., shading, competitive vegetation).
o Mechanical: Mowing, hand removal, heavy equipment, tillage, prescribed burning.
o Chemical: Herbicides, insecticides, fungicides, etc.
• Shading: Prevents plants from receiving sunlight; often used in aquatic areas.
5. CHEMICAL CONTROL – HERBICIDES
• Herbicide Classification:
o Selectivity: Selective (controls specific plants) vs. non-selective (controls most plants).
o Time of Application: Preemergence (applied before weed emergence), preplant,
postemergence.
o Action/Mobility: Contact (kills plant tissue on contact) vs. systemic (translocated
throughout plant).
o Mode of Action (MOA): Group classification (e.g., WSSA groups) to manage resistance.
• Key Herbicides for ROW:
o Glyphosate (e.g., Roundup®): Non-selective systemic; widely used; extensive resistance
concerns.
o 2,4-D: Selective systemic for broadleaf weeds.
o Dicamba: Broadleaf herbicide; requires annual training for dicamba-resistant crops.
o Triclopyr (e.g., Garlon®): Systemic for woody plants and broadleaf weeds.
o Imazapyr (e.g., Arsenal®): Non-selective systemic; persistent; effective against woody
species.
o Aminocyclopyrachlor (e.g., Perspective®): Long-residual ROW herbicide.
o Fluroxypyr (e.g., Vista®): Broadleaf control.
o Metsulfuron methyl (e.g., Escort®): Sulfonylurea herbicide for broadleaf weeds.
• Bare Ground Herbicides: Products like prometon (Pramitol®) for complete vegetation control
where needed.
6. APPLICATION METHODS & EQUIPMENT
• Ground Application: Boom sprayers, hand-held sprayers (spot treatment).
• Aerial Application: Helicopters or fixed-wing aircraft.
• Basal Bark & Cut Stump: For woody plant control.
• Soil Application (Granular): For preemergence control.
• Calibration: Essential for applying the correct rate; minimize off-target drift.
• Drift Management: Use low-drift nozzles, buffer zones, weather considerations (avoid
inversion).
7. ENVIRONMENTAL PROTECTION & SAFETY
• Sensitive Areas: Wetlands, endangered species habitat, surface water (apply specific buffer
distances per label).
• Pesticide Toxicity: Acute (LD₅₀) and chronic toxicity; route of entry (oral, dermal, inhalation,
ocular).
• Personal Protective Equipment (PPE): As specified on the label.
• Heat Stress: Apply appropriate measures for outdoor workers.
, Page 3 of 194
• Spill Management: Contain, report to appropriate authorities, and clean up per label and
regulations.
• Signal Words: DANGER-POISON (toxic), DANGER (corrosive), WARNING, CAUTION.
• First Aid & Medical: Provide emergency assistance and decontamination.
8. TARGET PESTS IN ROW
• Weeds: Johnsongrass, Canada thistle, musk thistle, kudzu, poison hemlock, wild carrot,
pigweeds, foxtail, marestail, common chickweed, dandelion, plantain, wild garlic, and various
woody species (e.g., multiflora rose, honey locust).
• Insects: Occasional pests (e.g., grasshoppers, borers).
• Pathogens: Rusts, smuts, etc., though herbicides are primary focus.
• Vertebrates: Voles, rodents (secondary).
9. IPM & MONITORING
• Identify the Pest: The first component of any effective pest management program.
• Collect Life Cycle Information: Pest life cycles, physiology, reproductive potential, past control
results.
• Monitor Control Strategies: To prevent ineffective, costly, or environmentally adverse
treatments.
• Record Information: Control measures, start dates, application rate, equipment used, crew,
environmental conditions, effectiveness evaluation, problems/complaints, damage claims.
• Site-Specific Factors: Urban, suburban, or rural areas; dry vs. wet lands; tourist/scenic areas;
wildlife habitat (critical nesting or feeding grounds).
10. TENNESSEE-SPECIFIC REQUIREMENTS
• Certification & Licensing: Must pass C06 exam; certification valid for 3 years with 12 CEUs (9
general, 3 category-specific). License must be renewed annually.
• Restricted-Use Pesticides (RUPs): Must be certified or under direct supervision of a certified
applicator.
• Private vs. Commercial Applicator: Private applicator becomes commercial when spraying for
another individual and charging a fee.
• Paraquat Safety Training: Annual training required for paraquat products.
• Dicamba Training: Annual training required for dicamba-resistant crops.
250 SCENARIO-BASED MULTIPLE-CHOICE QUESTIONS & RATIONALES (RANDOM ORDER)
1. A railroad maintenance crew plans to clear dense vegetation along a 5-mile stretch of track to prevent
fire hazards. Which statement best describes the primary management goal for the track area itself
(rails, ties, and ballast)?
A) Maintain a diverse mix of low-growing shrubs to reduce erosion.
B) Keep the track area completely bare of vegetation for safety and operational integrity.
, Page 4 of 194
C) Allow native grasses to grow to a height of 12 inches to provide wildlife habitat.
D) Apply selective herbicide that only controls broadleaf weeds while leaving grasses untouched.
Answer: B
Rationale: Railroad rights-of-way, especially the track area (rails, ties, and ballast), must be kept bare of
vegetation to ensure safe train operation, prevent fire, and allow for inspections. Herbicides are the
primary tool used to achieve bare-ground conditions along the track.
2. A commercial applicator in Tennessee is applying a restricted-use herbicide along a highway ROW.
The applicator has a valid certification but not a pest control operator license. What is required for the
applicator to legally perform the application?
A) The applicator must be under the direct supervision of a licensed pest control operator.
B) No further requirement is needed; certification alone is sufficient for all applications.
C) The applicator must have completed the restricted-use pesticide dealer course.
D) The applicator must obtain a separate permit from the county highway department.
