,Q1. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which
scenario constitutes a 'use inconsistent with the labeling' that would trigger
enforcement action?
A. Applying a pesticide at a concentration lower than the label rate to reduce
environmental impact.
B. Using a pesticide registered for agricultural use on a structural pest that is not listed
on the label but in the same pest class.
C. Mixing two pesticides together when the label of each product does not explicitly
prohibit tank mixing.
D. Applying a pesticide with equipment that has not been calibrated, even if the actual
dosage remains within label limits.
Correct Answer: B. Using a pesticide registered for agricultural use on a structural
pest that is not listed on the label but in the same pest class.
Rationale: FIFRA requires that all pesticide uses conform to the label; using a product for
a pest not listed, even if in the same class, is a 'use inconsistent with the labeling' and is
illegal. Lower concentrations, tank mixing (unless prohibited), and equipment calibration
(if dosage is correct) are not inherently violations.
Why Wrong:
A - Lower concentrations are generally permitted if efficacy is not compromised and
the label does not require a minimum rate.
C - Tank mixing is allowed unless the label explicitly prohibits it.
D - Equipment calibration is a best practice but not a labeling violation if the actual
application rate is correct.
Reference: FIFRA § 2(ee), 40 CFR Part 156; NC Pesticide Law G.S. 143-434
Q2. A pest control operator in North Carolina is applying a termiticide around a
public water well. The label requires a 50-foot buffer, but the operator notices the
label's buffer is based on a soil type that is not present on site. What is the operator's
obligation under the North Carolina Pesticide Law?
A. Proceed with the application because the label buffer is a default and can be adjusted
based on site-specific conditions.
B. Contact the NC Department of Agriculture for a written waiver of the buffer
requirement before applying.
C. Use a more restrictive buffer of 100 feet to be safe, since the label buffer is not
site-specific.
D. Apply the pesticide but document the soil type discrepancy in the service record to
justify the deviation.
Correct Answer: B. Contact the NC Department of Agriculture for a written waiver
of the buffer requirement before applying.
Page 3
, Rationale: North Carolina regulations require strict adherence to label instructions,
including buffer zones; any deviation must be authorized by the regulatory authority.
Self-adjusting buffers is a violation, even if scientifically justified. A more restrictive buffer
is not a substitute for label compliance.
Why Wrong:
A - Label instructions are legally binding; adjustments are not permitted without
regulatory approval.
C - Using a more restrictive buffer does not excuse deviation from the label; the label
is the law.
D - Documentation does not legalize an off-label application.
Reference: NC Pesticide Law G.S. 143-434; 2 NCAC 09L .0103
Q3. In an Integrated Pest Management (IPM) program for a municipal building,
monitoring reveals a cockroach infestation. According to advanced IPM principles,
which action sequence best aligns with regulatory and sustainability goals?
A. Immediately apply a residual insecticide to all baseboards, then seal cracks and
educate staff.
B. Identify the species, determine the source, implement sanitation and exclusion, then
use targeted baits only where needed.
C. Use a broad-spectrum space spray to reduce the population quickly, then follow up
with gel baits.
D. Initiate a regular schedule of preventive insecticide applications every quarter,
regardless of monitoring results.
Correct Answer: B. Identify the species, determine the source, implement sanitation
and exclusion, then use targeted baits only where needed.
Rationale: Advanced IPM prioritizes identification, non-chemical measures, and targeted
interventions. Broad-spectrum or scheduled applications contradict IPM and may violate
regulatory requirements for least-toxic methods. This sequence also reduces pesticide
resistance and environmental impact.
Why Wrong:
A - Immediate residual application is a reactive, non-IPM approach that ignores
source reduction.
C - Space sprays are broad-spectrum and disruptive, not a first-line IPM tactic.
D - Preventive scheduled applications are not IPM; they are calendar-based and often
unnecessary.

Q4. A technician is mixing a pesticide with a pH of 9.5 into a spray tank. Which
compatibility issue is most critical to consider?
