California PCA Laws and Regulations –
Verified Exam Questions and Answers
Question 1: The difference between California laws and DPR regulations is
that laws are
A. Passed by County Agricultural Commissioners and regulations are passed by
the California legislature
B. Passed by the California legislature and regulations are adopted by DPR to carry
out the laws
C. Supplements to federal regulations
D. Adopted by DPR to carry out regulations signed by the Governor
Correct ,,,answer,,,: B
Rationale: Laws are enacted by the California State Legislature. The Department
of Pesticide Regulation (DPR) is the state agency authorized to adopt regulations
that implement and enforce those laws. This is a fundamental concept in
administrative law: the legislature creates statutes, and agencies create regulations
to operationalize them .
Question 2: Which of the following is not one of the purposes of California's
pesticide and pest control laws and regulations?
A. Protecting workers from pesticide exposure
B. Providing proper, safe, and effective use of pesticides
,C. Encouraging people to use more pesticides
D. Protecting public health and safety
Correct ,,,answer,,,: C
Rationale: California's pesticide laws are designed to protect workers, ensure safe
pesticide use, and safeguard public health and the environment. Encouraging
increased pesticide use directly contradicts these protective goals. The state's
regulatory framework emphasizes integrated pest management (IPM) and
minimizing unnecessary pesticide applications .
Question 3: A cooperating agency that helps DPR enforce pesticide use laws
and regulations in California is the
A. County Department of Health
B. State Department of Water Resources
C. State Department of Labor
D. County Agricultural Commissioner
Correct ,,,answer,,,: D
Rationale: County Agricultural Commissioners (CACs) serve as the primary local
enforcement arm for DPR. They issue permits, inspect application sites, investigate
complaints, and enforce pesticide regulations within their respective counties. This
cooperative federal-state-local structure ensures effective oversight across
California's diverse agricultural regions .
,Question 4: County Agricultural Commissioners may adopt supplemental
pesticide regulations with the approval of the
A. Department of Pesticide Regulation
B. Office of the Governor
C. County Board of Supervisors
D. California State Legislature
Correct ,,,answer,,,: A
Rationale: While CACs can adopt additional local regulations to address unique
regional conditions, these supplemental rules require prior approval from DPR.
This ensures local requirements remain consistent with state law and do not create
conflicting standards across county lines .
Question 5: Which of the following is considered to be pesticide labeling?
A. Spray nozzle catalog
B. A printed pesticide advertisement
C. The federal Worker Protection Standard
D. A written recommendation
Correct ,,,answer,,,: C
Rationale: Under federal and state law, "labeling" includes not just the physical
label attached to the container but also all accompanying written, printed, or
graphic matter that references the pesticide. The Worker Protection Standard
(WPS)—a federal regulation that requires specific safety information—legally
functions as part of pesticide labeling for agricultural uses .
, Question 6: When a pesticide registrant allows a pesticide product
registration to lapse, pest control dealers
A. Must immediately return all unsold stock
B. Can sell and deliver the pesticide product for two years
C. Must retrieve all previously sold stock
D. Can indefinitely sell and deliver the pesticide product
Correct ,,,answer,,,: B
Rationale: When a company voluntarily allows registration to lapse, a grace
period is typically provided—up to two years—during which existing stocks can
still be sold and delivered. This prevents immediate economic hardship on dealers
and growers who have already purchased or committed to the product .
Question 7: When a pesticide product registration is cancelled, the sale and
use of this product
A. Is automatically prohibited under all circumstances
B. May continue under conditions imposed by the regulatory agency responsible
for the cancellation
C. Will be allowed for two years from the cancellation date
D. Is not affected as long as detailed sales records are kept current
Correct ,,,answer,,,: B
Rationale: When EPA or DPR cancels a registration, they typically establish a
"cancellation order" that may include provisions for existing stocks. These orders
specify allowable continued sale and use periods—often up to 18 months for use
and 12 months for sale—under strict conditions. The cancellation is rarely
immediate or absolute .
