What this exam covers
5 real sample questions
Under Oklahoma's Combined Pesticide Law, it is unlawful for a person to act, operate, or do business as a commercial, noncommercial, certified, temporary certified, service technician, or private applicator unless the person has done what?
A. Completed a single one-time online orientation video with no license required
B. Posted a surety bond with the county clerk
C. Registered as a business with the Oklahoma Secretary of State only
D. Obtained a valid applicator's license issued by the State Board of Agriculture for the category of pesticide application engaged in, unless applying to their own property
Show answer and reasoning

Correct answer: D. Obtained a valid applicator's license issued by the State Board of Agriculture for the category of pesticide application engaged in, unless applying to their own property

Correct. 2 O.S. Section 3-82(A)(1) makes it unlawful to act, operate, or do business or advertise in these categories unless the person has obtained a valid applicator's license from the State Board of Agriculture for the category engaged in, unless applying to their own property.

  • A: An orientation video does not substitute for a license; certification requires passing the required examinations under 2 O.S. Section 3-82(B).
  • B: A county surety bond is not the licensing mechanism used under the Combined Pesticide Law; licensing runs through the State Board of Agriculture.
  • C: General business registration with the Secretary of State does not satisfy the pesticide applicator licensing requirement, which is administered separately by the State Board of Agriculture.
Source: 2 O.S. § 3-82(A)(1)
Under the Combined Pesticide Law's definitions, what distinguishes a "commercial applicator" from a "noncommercial applicator"?
A. There is no legal distinction; the terms are interchangeable under Oklahoma law
B. A commercial applicator must be a licensed veterinarian, while a noncommercial applicator has no education requirement
C. A commercial applicator only works with restricted-use pesticides while a noncommercial applicator only works with general-use pesticides
D. A commercial applicator engages in commercial application of pesticides for hire or compensation, while a noncommercial applicator uses or supervises use of restricted-use pesticides under an owner or manager of property, not for hire
Show answer and reasoning

Correct answer: D. A commercial applicator engages in commercial application of pesticides for hire or compensation, while a noncommercial applicator uses or supervises use of restricted-use pesticides under an owner or manager of property, not for hire

Correct. 2 O.S. Section 3-81(9)-(10) defines a commercial applicator as one engaged in commercial application of pesticides or devices, while a noncommercial applicator uses or supervises restricted-use pesticide application under an owner or manager of property, such as a government employee applying pesticides in official duties.

  • A: The Combined Pesticide Law defines these as distinct, separately regulated categories, not interchangeable terms.
  • B: Neither category has a veterinary licensure requirement; this is not a distinction recognized under the statute.
  • C: The distinction is not based on which class of pesticide is used; both categories can involve restricted-use pesticides depending on the application.
Source: 2 O.S. § 3-81(9)-(10)
Under the Combined Pesticide Law, a "private applicator" is a person who uses or supervises the use of a restricted-use pesticide for what purpose?
A. Selling pesticides at a retail dealer location
B. Fumigating apartment buildings for a pest control company
C. Producing any agricultural commodity on property owned or rented by the person or employer, or on another's property if applied without compensation other than trading of personal services between producers
D. Applying pesticides for hire to residential lawns in an urban subdivision
Show answer and reasoning

Correct answer: C. Producing any agricultural commodity on property owned or rented by the person or employer, or on another's property if applied without compensation other than trading of personal services between producers

Correct. 2 O.S. Section 3-81(35) defines a private applicator as a person who uses or supervises the use of a restricted pesticide for producing an agricultural commodity on property owned or rented by the person or employer, or on another producer's property without compensation beyond trading of personal services.

  • A: Selling pesticides at retail is governed by the dealer permit provisions, not the private applicator definition.
  • B: Fumigating apartment buildings for a company is commercial pesticide application, not agricultural production on one's own or a neighbor's property.
  • D: Applying pesticides for hire on residential lawns is commercial application, which falls under the commercial applicator definition, not private applicator.
Source: 2 O.S. § 3-81(35)
In Oklahoma, an applicant seeking commercial or noncommercial pesticide applicator certification must pass which exam before taking a category-specific exam, unless the applicant is only seeking a private applicator license?
A. The Core exam, which covers equipment, safety, and laws applicable to all categories
B. A state real estate licensing exam
C. The federal EPA Series 300 pilot certification exam
D. The category exam only, with no core exam required
Show answer and reasoning

Correct answer: A. The Core exam, which covers equipment, safety, and laws applicable to all categories

Correct. Per ODAFF's certification structure and OAC 35:30-17-1, commercial and noncommercial applicants must pass the Core exam, covering equipment, safety, laws, and other knowledge applicable to all categories, before or alongside a category exam. Private applicators are not required to take the Core exam.

  • B: A real estate exam has no relationship to pesticide applicator certification.
  • C: An FAA pilot certification exam is unrelated to the ODAFF Core pesticide exam, though aerial applicators separately must hold valid FAA credentials under 2 O.S. Section 3-82(A)(3).
  • D: The category exam alone is not sufficient; ODAFF requires the Core exam to be passed first for commercial and noncommercial applicants.

Oklahoma's pesticide applicator licensure exam program is administered through a third-party testing vendor under contract with ODAFF. What passing score must an applicant achieve on a written certification exam?
A. 80 percent or above
B. 90 percent or above
C. 60 percent or above
D. 70 percent or above
Show answer and reasoning

Correct answer: D. 70 percent or above

Correct. ODAFF, administering exams through PSI Services LLC under OAC 35:30-17-4, requires an applicant to attain a satisfactory score of 70 percent or above to pass any written exam.

  • A: 80 percent overstates the passing threshold; ODAFF's requirement is 70 percent.
  • B: 90 percent overstates the passing threshold well beyond ODAFF's actual 70 percent requirement.
  • C: 60 percent is below the passing threshold ODAFF requires for its written exams.
