SECTION 1: LAWS AND REGULATIONS
Question 1
Under Wisconsin law, how long must commercial applicators keep records of
restricted-use pesticide applications?
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Answer: B) 2 years
Rationale: Under ATCP 29, commercial applicators and all applicators using
restricted-use pesticides (RUPs) must maintain application records for a minimum
of 2 years. Private applicators must also keep RUP records for 2 years. This allows
DATCP and EPA to conduct audits and investigate potential violations or incidents.
Question 2
What federal law is the primary legislation regulating pesticide production,
transportation, sale, use, and disposal in the United States?
A) Clean Water Act
B) FIFRA
C) CERCLA
D) TSCA
Answer: B) FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act)
,Rationale: FIFRA (originally enacted in 1947, significantly amended in 1972) is the
cornerstone federal pesticide law. It gives EPA the authority to register pesticides,
classify them as general-use or restricted-use, and regulate their sale and use. The
Clean Water Act and CERCLA address water quality and hazardous waste, while
TSCA covers chemicals generally.
Question 3
Which Wisconsin administrative code chapter governs pesticide use and control,
including certification, licensing, and recordkeeping?
A) ATCP 10
B) ATCP 20
C) ATCP 29
D) ATCP 30
Answer: C) ATCP 29
Rationale: ATCP 29 ("Pesticide Use and Control") is Wisconsin's primary state
pesticide law administered by DATCP. It covers applicator certification and
licensing, training requirements, recordkeeping, mixing/loading rules, and
enforcement. ATCP 30 specifically addresses pesticide product restrictions for
certain high-risk pesticides.
Question 4
What is the minimum passing score on the Wisconsin pesticide applicator
certification exam for commercial applicators?
A) 60%
B) 70%
C) 75%
D) 80%
Answer: B) 70%
Rationale: Commercial applicators must achieve a score of 70% or higher to pass
the Wisconsin certification exam. Private applicators must also score 70%, but
,they have an alternative pathway—if they complete an approved training
program, the passing score may be reduced to 50%. This recognizes that private
applicators typically undergo more hands-on training.
Question 5
How often must commercial pesticide applicators renew their certification in
Wisconsin?
A) Every 2 years
B) Every 3 years
C) Every 5 years
D) Every 10 years
Answer: C) Every 5 years
Rationale: Wisconsin pesticide applicator certifications are valid for 5 years from
the date of issuance. Renewal requires continuing education credits—typically a
minimum of 4 credits per certification category per renewal period. Failure to
renew on time requires retaking the exam.
Question 6
What is the minimum age requirement to become a certified pesticide
applicator in Wisconsin under current rules?
A) 16 years old
B) 17 years old
C) 18 years old
D) 21 years old
Answer: C) 18 years old
Rationale: Under current Wisconsin regulations (ATCP 29), applicants must be at
least 18 years old to be certified as a private or commercial pesticide applicator.
Note: Proposed rule changes may adjust this age requirement, but as of 2026, 18
remains the minimum.
, Question 7
Which of the following is NOT a legal deviation from pesticide label directions
under Wisconsin and federal law?
A) Applying a lower rate than specified
B) Applying against a pest not listed on the label at a listed site
C) Applying at a higher concentration than specified on the label
D) Mixing with another pesticide not prohibited by the label
Answer: C) Applying at a higher concentration than specified on the label
Rationale: FIFRA and Wisconsin law allow four specific deviations from label
directions:
1. Lower rate or frequency
2. Unlisted pest on listed site
3. Unlisted (non-prohibited) method
4. Mixing with another product if not prohibited
Applying at a higher concentration/rate than specified is NEVER allowed—it
constitutes a violation and can lead to crop damage, illegal residues,
environmental harm, and enforcement action.
Question 8
Who enforces Wisconsin's pesticide laws and regulations?
A) Wisconsin DNR
B) Wisconsin DATCP
C) Wisconsin EPA
D) Wisconsin Department of Health
Answer: B) Wisconsin DATCP
Rationale: The Wisconsin Department of Agriculture, Trade and Consumer
Protection (DATCP) is the primary enforcement agency for Wisconsin's pesticide
