SECTION 1: FEDERAL PESTICIDE LAWS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A commercial applicator in Fresno County applies a newly registered herbicide to a cotton
field. Three days later, the EPA issues an emergency suspension of the product under Section
6 of FIFRA due to newly discovered risks to endangered species. The applicator still has 200
gallons of the product in his storage facility. Under federal law, what is his legal obligation
regarding this remaining product?
A. He may continue to use the product until his current supply is exhausted, provided he
follows all label directions
B. He must immediately cease all use, sale, and distribution of the product and may not
dispose of it without EPA authorization ✓ CORRECT
C. He must return the unused product to the manufacturer within 30 days of the suspension
notice
D. He may use the product for non-agricultural purposes only, such as structural pest control
Correct Answer: B
Rationale: Under FIFRA Section 6, an emergency suspension immediately prohibits all sale,
distribution, and use of the suspended pesticide; possession of existing stock is permitted
only under strict conditions, and any disposal requires EPA authorization. Option A is
incorrect because an emergency suspension does not allow continued use of existing stock
— that provision applies only to voluntary cancellations or certain label amendments, not
suspensions. On the QAL exam, remember that suspensions are immediate and absolute,
while cancellations may have existing stock provisions.
Question 2 of 50
A pesticide manufacturer submits a new insecticide registration application to the EPA. The
active ingredient has never been registered before. Under FIFRA Section 3, which of the
,following data requirements must the manufacturer provide to demonstrate that the pesticide
will not cause unreasonable adverse effects?
A. Only efficacy data showing the product controls the target pest effectively
B. Only environmental fate studies demonstrating the product does not persist in soil
C. Toxicology data, environmental fate studies, residue chemistry data, and ecological effects
data ✓ CORRECT
D. Only residue chemistry data for crops intended for human consumption
Correct Answer: C
Rationale: FIFRA Section 3 requires a complete data package including toxicology,
environmental fate, residue chemistry, and ecological effects studies before the EPA can
register a new active ingredient; no single category of data alone satisfies the statutory
standard of no unreasonable adverse effects. Option B is incorrect because environmental
fate studies alone are insufficient — the EPA must evaluate human health, ecological, and
residue data together to make a registration determination. On the QAL exam, know that
FIFRA registration requires a comprehensive data package, not isolated studies.
Question 3 of 50
A structural pest control operator in Sacramento treats a commercial building with a
registered termiticide. Two weeks later, the building owner reports that the termiticide has
lost effectiveness and demands a refund. The operator discovers that the product label
specifies re-treatment intervals of no less than 12 months. The operator wants to re-treat
immediately. Under FIFRA, what governs this situation?
A. The operator may re-treat at any time if the customer provides written consent
B. The operator must follow the label-specified re-treatment interval and cannot legally
re-treat before 12 months ✓ CORRECT
C. The operator may re-treat immediately if he uses a different active ingredient
D. The operator must notify the EPA regional office before any re-treatment
Correct Answer: B
Rationale: Under FIFRA, the pesticide label is a legally binding document, and using a product
in a manner inconsistent with its labeling is a violation of federal law; re-treatment intervals
are enforceable restrictions that must be followed regardless of efficacy concerns. Option A
is incorrect because customer consent does not override federal labeling requirements — no
private agreement can authorize a use that violates FIFRA. On the QAL exam, remember that
the label is the law under FIFRA, and deviations require EPA approval, not customer
permission.
Question 4 of 50
, A California agricultural commissioner inspects a farm in Kern County and finds an
unregistered pesticide product being used on almonds. The product was manufactured in
Mexico and smuggled across the border. The commissioner wants to take enforcement
action. Under federal law, what is the legal status of this product?
A. The product is legal to use if it is chemically identical to a registered U.S. product
B. The product is an illegal pesticide under FIFRA because all pesticides distributed or sold in
the United States must be registered with the EPA ✓ CORRECT
C. The product is legal for personal use on the farmer's own property only
D. The product is legal if the farmer obtained it through a valid EPA experimental use permit
Correct Answer: B
Rationale: FIFRA Section 12(a)(1)(A) prohibits the distribution or sale of any unregistered
pesticide in the United States, and importation without registration constitutes a violation
regardless of chemical similarity to registered products. Option A is incorrect because
chemical identity to a registered product does not exempt an unregistered pesticide from
FIFRA's registration requirement — each product must be separately registered with the EPA.
On the QAL exam, know that registration is product-specific, not active-ingredient-specific,
and unregistered pesticides are illegal regardless of origin or similarity.
Question 5 of 50
A food processing facility in the Central Valley uses a registered sanitizer on food-contact
surfaces. The EPA has established a tolerance for residues of the active ingredient on raw
agricultural commodities under the Federal Food, Drug, and Cosmetic Act (FFDCA). The
facility wants to know whether this tolerance also covers residues on processed foods.
Under federal law, how does this work?
A. The raw agricultural commodity tolerance automatically applies to all processed foods
derived from that commodity
B. A separate food additive tolerance or exemption must be established under FFDCA Section
408 for processed food residues ✓ CORRECT
C. The EPA tolerance only applies to pesticides applied directly by farmers, not to sanitizers
used in processing facilities
D. The facility is exempt from tolerance requirements because sanitizers are not classified as
pesticides
Correct Answer: B
Rationale: Under FFDCA Section 408, raw agricultural commodity tolerances and processed
food tolerances are separate regulatory determinations; residues in processed foods require
either a specific tolerance or an exemption from the requirement of a tolerance. Option A is
incorrect because raw agricultural commodity tolerances do not automatically extend to
processed foods — concentrated or altered residues in processing may exceed safe levels
and require separate regulatory evaluation. On the QAL exam, distinguish between Section
