– Category 6 (Right-of-Way Pest Control) exam ACTUAL
QUESTIONS AND ANSWERS LATEST UPDATE THIS YEAR
Oklahoma Commercial Pesticide Applicator Certification – Category 6 (Right-of-Way Pest
Control) exam question set, written to your specifications.
First, the actual exam coverage in summarized point form based on Oklahoma Department of
Agriculture, Food, and Forestry (ODAFF) standards for Category 6 Right-of-Way :
• Laws and Regulations (Federal & Oklahoma): FIFRA (Federal Insecticide, Fungicide, and
Rodenticide Act), Oklahoma Pesticide Law (2 O.S. § 3-81 to 3-94), ODAFF enforcement authority,
Oklahoma Administrative Code (OAC) rules, Endangered Species Act (ESA), Worker Protection
Standard (WPS), recordkeeping requirements (location, date, product, amount applied),
licensing and certification through ODAFF and PSI Services
• Pest Identification and Biology (Right-of-Way Specific): Plant life cycles (annual, biennial,
perennial), weed identification (Canada thistle, Johnsongrass, musk thistle, tree-of-heaven,
poison ivy, multiflora rose, sericea lespedeza, kudzu), woody plant identification, vine control
challenges, growth stages (seedling, vegetative, reproductive, maturity), meristem location and
herbicide susceptibility
• Right-of-Way Vegetation Management Areas: Roadsides (safety recovery zone, sight distance,
sign visibility, drainage), railroads (track inspection, fire prevention, crossing visibility, OAC
165:32-1-11 weed abatement requirements), electric utility lines (conductor clearance,
structure inspection, emergency access), pipelines (aerial inspection, leak detection, pumping
stations), industrial sites (substations, tank farms, storage yards)
• Integrated Pest Management (IPM) and Integrated Vegetation Management (IVM): Scouting
and monitoring (mile-by-mile inventory), action thresholds, combining cultural methods
(mowing, prescribed fire, mulching), mechanical methods (cutting, flail mowers, hand removal),
biological control (musk thistle head weevil, leafy spurge flea beetle), chemical control
(herbicides as part of IVM), prevention strategies (weed-free seed, competitive species
establishment)
• Herbicide Classes and Modes of Action: Selective vs. nonselective herbicides, contact vs.
systemic (translocated) herbicides, preemergence vs. postemergence, persistent vs.
nonpersistent, soil-applied herbicides (xylem translocation), foliar-applied herbicides (phloem
translocation), specific herbicide families (phenoxy, benzoic, pyridine carboxylic acids,
glyphosate, ALS inhibitors)
• Application Equipment and Calibration: Boom sprayers (calibration formula: GPA = (GPM ×
5940) ÷ (MPH × nozzle spacing)), handgun and backpack sprayers, granular spreaders (rotary,
drop), wiper applicators, calibration for different speeds and nozzle types, nozzle selection (flat
fan, cone, flood jet, air induction)
• Application Methods for Rights-of-Way: Foliar broadcast, directed spot treatment, wiper
application, basal bark (lower 12-24 inches of stem), cut stump, soil spot treatment, granular
application, selective timing for different weed species, seasonal considerations (dormant
season vs. growing season)
• Drift Management and Environmental Protection: Temperature inversions, wind speed limits
(3-10 mph optimal), droplet size (coarse/very coarse), boom height, buffer zones (sensitive
, Page 2 of 128
crops, water bodies, residential areas), drift reduction technology (air induction nozzles, drift
control adjuvants), volatility (ester vs. amine formulations), runoff prevention, leaching potential
• Noxious Weeds and Invasive Species (Oklahoma Specific): State noxious weed list (Canada
thistle, musk thistle, Johnsongrass, field bindweed, hoary cress), prohibited species, restricted
species, ODAFF noxious weed law enforcement, mandatory control requirements, spread
prevention (cleaning equipment between sites)
• Public Relations and Communication: Addressing landowner concerns (fruit trees, gardens,
crops), explaining necessity and benefits of right-of-way vegetation management, handling
complaints (drift, brownout/discoloration), providing advance notice, respecting sensitive areas,
educating the public about IVM practices
• Safety and Worker Protection: Personal protective equipment (PPE) for mixing, loading, and
application, Restricted-Entry Intervals (REI), decontamination supplies (WPS requirements), first
aid for pesticide exposure (eye flushing, skin decontamination), pesticide poisoning symptoms,
heat stress prevention in PPE
• Storage, Transport, Disposal, and Spill Response: Proper storage conditions (original containers,
secure area, temperature control), spill kit components (absorbents, PPE, shovel, disposal bags),
spill containment procedures, ODAFF spill reporting (when required), triple rinsing of containers,
rinsate disposal, Clean Sweep disposal program
• Non-Target Organisms and Pollinator Protection: Protecting honeybees and native pollinators
(avoid spraying blooming plants, apply at dawn/dusk), aquatic organism protection (buffer
zones, no direct application to water), birds and wildlife, endangered and threatened species in
Oklahoma
1. Which federal law primarily governs the registration, labeling, and use of pesticide products in the
United States for right-of-way applications?
A) Clean Water Act
B) Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C) Resource Conservation and Recovery Act
D) Occupational Safety and Health Act
Correct: B – FIFRA is the principal federal statute that regulates the distribution, sale, and application of
pesticides, requiring registration and proper labeling for all uses including right-of-way .

2. In Oklahoma, which agency is designated as the lead authority for enforcement of pesticide licensing
and compliance for commercial applicators?
A) Oklahoma Department of Environmental Quality (ODEQ)
B) Oklahoma Department of Agriculture, Food, and Forestry (ODAFF)
C) Oklahoma Conservation Commission
D) Oklahoma State Department of Health
Correct: B – ODAFF administers the state pesticide program, issuing licenses and enforcing compliance
with state pesticide regulations including Category 6 right-of-way .
3. A right-of-way maintenance crew encounters a federally listed endangered plant species during
herbicide application. Under the Endangered Species Act (ESA), the crew must:
A) Continue application as planned since the plant is not a target weed
B) Obtain a permit before taking any action that could affect the listed species
C) Notify the local county commissioner before proceeding
D) Apply herbicide at half rate to minimize potential impact
Correct: B – ESA protection applies to species listed as endangered or threatened; any activity that could
"take" (harm, harass, or kill) such species requires a permit or must follow label restrictions .

4. Which of the following record-keeping elements is required by Oklahoma law after a pesticide
application on a right-of-way corridor?
A) Weather forecast for the next 24 hours
B) GPS coordinates or specific location, date, product name, and amount applied
C) Names of all nearby landowners within 500 feet
D) Estimated cost of the application per acre
Correct: B – Oklahoma regulations mandate documentation of location (specific enough to identify
treated area), date, product name, and quantity applied to ensure traceability and compliance .
5. The Worker Protection Standard (WPS) primarily addresses which of the following concerns for right-
of-way pesticide operations?
A) Vehicle emissions from right-of-way maintenance equipment
B) Safety and health of workers handling pesticides or entering treated areas
C) Noise pollution from pesticide spraying equipment
D) Soil erosion control measures along treated rights-of-way
Correct: B – WPS sets requirements for training, personal protective equipment (PPE), restricted-entry
