Arkansas Pesticide Applicator Certification
Exam
200 Complex Practice Questions | Arkansas State Plant Board (ASPB)
1. Under Arkansas law, which state agency is primarily responsible for regulating pesticide
applicators and enforcing the Arkansas Pesticide Control Act?
A) Arkansas Department of Health B) Arkansas Department of Agriculture — Plant Industry
Division (formerly Arkansas State Plant Board) C) Arkansas Department of Environmental
Quality D) Arkansas Cooperative Extension Service
(Correct Answer: B) Arkansas Department of Agriculture — Plant Industry Division
Rationale: The Arkansas Department of Agriculture, through its Plant Industry Division,
administers the Arkansas Pesticide Control Act (Ark. Code Ann. §20-20-201 et seq.), regulates
pesticide applicators, issues licenses and certifications, investigates complaints, and enforces
penalties for violations. The ASPB was merged into the Arkansas Department of Agriculture in
2019.
2. A commercial pesticide applicator in Arkansas applies a restricted-use pesticide (RUP)
without a valid license. Under the Arkansas Pesticide Control Act, the maximum civil
penalty per violation is:
A) $500 B) $1,000 C) $5,000 D) $10,000
(Correct Answer: C) $5,000 Rationale: Under Ark. Code Ann. §20-20-212, civil penalties for
violations of the Arkansas Pesticide Control Act may not exceed $5,000 per violation. Criminal
penalties may also apply for willful violations. Each day of a continuing violation may constitute
a separate violation, potentially resulting in cumulative penalties significantly exceeding the per-
day maximum.
3. In Arkansas, a "private applicator" is BEST defined as:
A) Any individual who applies pesticides for hire on any property B) A certified individual who
uses or supervises the use of restricted-use pesticides for purposes of producing an agricultural
commodity on property owned or rented by the applicator or their employer C) An individual
who applies general-use pesticides only on their own property D) Any homeowner who applies
pesticides to their residential lawn
,(Correct Answer: B) A certified individual using RUPs for producing agricultural
commodities on property owned/rented by the applicator or employer Rationale: Under
FIFRA and Arkansas law, a private applicator must be certified but uses RUPs only for
producing an agricultural commodity — on property they own, rent, or manage as an employee.
They do NOT apply pesticides for hire. This distinguishes them from commercial applicators
who apply pesticides for compensation or employ others to do so.
4. Which of the following applicators in Arkansas must obtain a COMMERCIAL
applicator license rather than a private applicator certification?
A) A soybean farmer who applies his own herbicides to his own fields B) A farm employee who
applies RUPs under the direct supervision of a certified private applicator on the employer's land
C) A lawn care company owner who applies pesticides to customers' properties for a fee D) A
farm manager who applies pesticides on land managed for an absentee landowner without
compensation
(Correct Answer: C) A lawn care company owner who applies pesticides to customers'
properties for a fee Rationale: Applying pesticides for compensation or hire — including
employees of pest control businesses, lawn care operations, or any commercial entity — requires
commercial applicator licensure. The key distinction is applying pesticides FOR OTHERS for
compensation vs. applying on one's own (or employer's) property for producing agricultural
commodities.
5. A pesticide label states "DO NOT apply when wind speed exceeds 10 mph." This
instruction is:
A) A recommendation that can be disregarded when the applicator exercises professional
judgment B) A legally binding requirement that must be followed exactly as written — violating
label instructions violates FIFRA and Arkansas law C) A guideline applicable only to aerial
applications D) A suggestion that applies only to sensitive areas adjacent to the application site
(Correct Answer: B) A legally binding requirement that must be followed exactly as
written Rationale: Under FIFRA §12(a)(2)(G), it is unlawful to use any registered pesticide in a
manner inconsistent with its labeling. The label is the law — all instructions, restrictions, and
precautionary statements are legally binding on all applicators. "The label is the law" is the
foundational principle of pesticide regulation under both FIFRA and the Arkansas Pesticide
Control Act.
6. A pesticide label lists the active ingredient as "chlorpyrifos" at a certain concentration.
An applicator mixes the product at DOUBLE the label rate to improve efficacy. This is:
, A) Permissible if the applicator holds a commercial license B) Permissible if the higher rate was
previously effective and is scientifically justified C) A violation of FIFRA regardless of the
applicator's credentials or justification D) Permissible only for licensed commercial applicators
with 5+ years of experience
(Correct Answer: C) A violation of FIFRA regardless of credentials or justification
Rationale: Applying pesticides at rates above the label maximum rate is a direct violation of
FIFRA and Arkansas pesticide law. Label rates are established through extensive toxicological
testing, residue studies, and efficacy data — exceeding them can result in illegal residues on food
crops, environmental contamination, and harm to non-target organisms. No credential or
professional judgment justifies exceeding label rates.
7. The "signal word" on a pesticide label indicates:
A) The type of pest the pesticide controls B) The relative acute toxicity of the pesticide to
humans — from most to least toxic: DANGER, WARNING, CAUTION C) The environmental
persistence of the pesticide D) The storage requirements for the pesticide product
(Correct Answer: B) The relative acute toxicity of the pesticide to humans — DANGER
(most toxic), WARNING (moderately toxic), CAUTION (least toxic) Rationale: Signal
words indicate acute toxicity category: DANGER/POISON (with skull and crossbones) =
Toxicity Category I (most hazardous, LD50 <50 mg/kg oral), DANGER alone may also indicate
severe eye/skin effects; WARNING = Category II (LD50 50–500 mg/kg); CAUTION =
Categories III and IV (LD50 >500 mg/kg). Signal words are required by FIFRA and EPA
regulations on all registered pesticide labels.
8. A pesticide has an oral LD50 of 45 mg/kg in rats. What signal word is required on this
product's label?
A) CAUTION B) WARNING C) DANGER D) No signal word is required for this toxicity level
(Correct Answer: C) DANGER Rationale: Toxicity Category I requires the signal word
DANGER: oral LD50 ≤50 mg/kg (rat). At 45 mg/kg, this product falls in Category I. Category I
also requires the skull and crossbones symbol and the word "POISON" on the label. This is the
most acutely toxic category and requires the most stringent protective equipment and handling
precautions.
9. A commercial applicator in Arkansas applying pesticides for mosquito control in a
residential neighborhood observes wind speeds increasing to 15 mph during the
Exam
