,Section 1: Federal & Wisconsin Pesticide Laws and Regulations
Q1: Under Wisconsin Administrative Code ATCP 29.31(5), what is the primary scope of
Category 3.0 Turf & Landscape certification?
A. Pesticide applications to agricultural field crops only.
B. Pesticide applications in greenhouses and commercial nurseries only.
C. Using or directing pesticide use to control pests affecting turf or landscape. [CORRECT]
D. Pesticide applications to utility and transportation rights-of-way only.
Correct Answer: C
Rationale: Category 3.0 covers pesticides used or directed to control pests affecting turf or
landscape. Greenhouse/nursery and right-of-way work are addressed under other categories.
Q2: Which set of requirements generally applies before an individual makes pesticide
applications for hire in Wisconsin?
A. Appropriate category certification and a current individual license; the business must also
hold its required pesticide business license [CORRECT]
B. A pesticide dealer license and a private applicator card only
C. A business license only, because employees are covered automatically
D. A pesticide training certificate without DATCP certification or licensing
Correct Answer: A
Rationale: Wisconsin generally requires a for-hire applicator to be certified in the appropriate
category and individually licensed, and the business to hold its required license. A training
certificate or business license alone is not sufficient.
Q3: A lawn-care company is hired to treat weeds on a public road right-of-way. Its employee
holds only Category 3.0 Turf & Landscape certification. What should the supervisor do?
A. Proceed because all outdoor vegetation is included in Category 3.0.
B. Proceed if the customer signs a waiver.
C. Apply only at a lower rate to avoid a category violation.
D. Do not make the application until the business confirms the appropriate certification
category and all other requirements for the right-of-way use. [CORRECT]
Correct Answer: D
Rationale: Category 3.0 is not a substitute for the category required for right-of-way work. A
waiver or lower rate does not expand the applicator's certification scope.

, Q4: A landscape company opens a second permanent office that regularly accepts pesticide
application orders and operates crews. What should the business check before conducting
work from that location?
A. No additional business license is needed if the company already has one office license.
B. Whether DATCP requires a separate Commercial Pesticide Business License for the
additional business location. [CORRECT]
C. Whether the office can use another company's applicator number.
D. Whether the branch can use a private applicator certificate instead.
Correct Answer: B
Rationale: Wisconsin requires a commercial pesticide business license for each qualifying
business location. An existing license for another location or another firm's number does not
automatically cover the new site.
Q5: For how long is Wisconsin commercial pesticide applicator certification generally valid,
unless suspended or revoked?
A. Five years [CORRECT]
B. One calendar year
C. Two years
D. Indefinitely after the first exam
Correct Answer: A
Rationale: Commercial certification is generally valid for five years. Annual individual and
business licenses are separate from the five-year certification.
Q6: A turf-care employee supervises a crew and directs pesticide use but does not personally
hold the spray wand. Which statement is most accurate?
A. Only the person holding the spray wand can need certification.
B. The employee is exempt if the product is a herbicide.
C. The employee needs no credentials when a customer is present.
D. Directing pesticide use can itself require the appropriate certification and commercial
licensing. [CORRECT]
Correct Answer: D
Rationale: Wisconsin requirements can apply to a person who directs pesticide use, not only
the person who physically applies it. The product type or customer's presence does not create
a blanket exemption.
