Virginia Commercial Pesticide
Applicator CORE Exam 2026-2027 |
Essential Q&A & Study Notes for
VDACS Certification
1. Under Virginia law, what is the maximum civil penalty that can be assessed
per violation of the Pesticide Control Act?
a) $500
b) $1,000
c) $5,000
d) $10,000
**Answer: b) $1,000***
*Rationale: Virginia law authorizes civil penalties of up to $1,000 for each violation of
the Virginia Pesticide Control Act. Criminal penalties can be higher but are reserved for
knowing and willful violations.
2. Which of the following is the correct definition of "direct supervision" as it
applies to a registered technician using a restricted-use pesticide?
a) The certified applicator must be physically present at the application site at all
times
b) The certified applicator must be within 2 hours of travel time from the site
c) The certified applicator must be available by phone and within 50 miles
d) The certified applicator must check the site within 24 hours of application
Answer: a) The certified applicator must be physically present at the application
site at all times
Rationale: For restricted-use pesticides, a registered technician must have a certified
commercial applicator physically on-site and directly overseeing the application.
General-use pesticides do not require this level of supervision.
3. When must a commercial applicator in Virginia submit a written report to
VDACS following a reportable pesticide incident?
a) Within 24 hours of the verbal report
,3|Page
b) Within 10 days of the incident
c) Within 30 days of the incident
d) Only if the incident involved more than 5 gallons of pesticide
Answer: b) Within 10 days of the incident
Rationale: After the required verbal notification within 48 hours, the applicator must
provide a detailed written report to VDACS within 10 days.
4. Which of the following is an example of a "residual" pesticide?
a) A pesticide that breaks down immediately upon contact with sunlight
b) A pesticide that remains active in the environment for an extended period
c) A pesticide that only works when applied to seeds
d) A pesticide that has no effect on non-target organisms
Answer: b) A pesticide that remains active in the environment for an extended
period
Rationale: Residual pesticides persist for weeks, months, or even years, providing long-
term control but also posing risks of carryover injury to rotational crops.
5. What is the primary function of an "emulsifier" in an emulsifiable
concentrate (EC) formulation?
a) To dissolve the active ingredient
b) To allow the oil-based pesticide to mix uniformly with water
c) To increase the droplet size of the spray
d) To neutralize the pH of the spray water
Answer: b) To allow the oil-based pesticide to mix uniformly with water
Rationale: Emulsifiers are surface-active agents that allow oil-soluble pesticides to form
stable emulsions when mixed with water, preventing them from separating.
6. Which of the following is NOT considered a potential route of pesticide
exposure?
a) Oral (ingestion)
b) Dermal (skin absorption)
c) Ocular (eye contact)
d) Olfactory (smell)
Answer: d) Olfactory (smell)
Rationale: The four primary routes of pesticide exposure are dermal, oral, inhalation,
, 4|Page
and ocular. While smelling a pesticide may indicate its presence, the olfactory system is
not a primary route of toxic absorption.
7. What is the primary reason for maintaining a "buffer zone" during pesticide
application?
a) To provide a space for equipment turnaround
b) To protect sensitive areas such as water bodies, schools, and endangered species
habitats from pesticide exposure
c) To allow weeds to grow as a trap crop
d) To increase the application rate on the target area
Answer: b) To protect sensitive areas such as water bodies, schools, and
endangered species habitats from pesticide exposure
Rationale: Buffer zones are legally required on many labels to mitigate off-target
movement of pesticides through drift or runoff into sensitive environments.
8. A pesticide applicator notices that a spray mixture is foaming excessively.
What adjuvant should they consider adding to the tank?
a) Surfactant
b) Drift retardant
c) Defoamer or anti-foam agent
d) Sticker
Answer: c) Defoamer or anti-foam agent
Rationale: Defoamers break down foam in the spray tank, preventing cavitation in the
pump and ensuring accurate flow rates through the nozzles.
9. In Virginia, which of the following is a valid reason for immediate suspension
of a commercial applicator's certification?
a) Failing to attend a recertification course on time
b) Repeated minor recordkeeping errors
c) Applying a pesticide in a manner that causes imminent danger to public health or
the environment
d) Disagreeing with a VDACS inspector's interpretation of a label
Answer: c) Applying a pesticide in a manner that causes imminent danger to
public health or the environment
