Virginia Commercial Pesticide Applicator CORE Exam
2026-2027 • 50 Questions • 100% VERIFIED
Introduction
This assessment serves as a definitive examination evaluation resource for candidates preparing
for the Virginia Commercial Pesticide Applicator CORE Exam (2026-2027) Comprehensive
Assessment. Designed to measure regulatory compliance and technical competence in commercial
chemical management, this question bank rigorously addresses key content domains mapped to the
official Virginia Department of Agriculture and Consumer Services (VDACS) blueprint. Key domains
evaluated include the Virginia Pesticide Control Act, EPA Regulations and FIFRA, Pesticide Safety
and Toxicity, Environmental Protection, Integrated Pest Management (IPM), Application Equipment
and Calibration, and Label Comprehension. Mastery of these statutory standards and safety
protocols is essential for achieving professional state licensure, protecting public health and natural
ecosystems, and executing safe, compliant pesticide operations across Virginia.
Question 1: Under the Virginia Pesticide Control Act, which state agency is authorized to regulate
the certification, licensing, registration, and enforcement of pesticide operations across Virginia?
A) Virginia Department of Agriculture and Consumer Services (VDACS).
B) Virginia Department of Environmental Quality (DEQ).
C) Virginia Department of Health (VDH).
D) Virginia Department of Forestry (VDF).
Correct Answer: A) Virginia Department of Agriculture and Consumer Services (VDACS).
Rationale: The Virginia Department of Agriculture and Consumer Services (VDACS), through
the Virginia Pesticide Control Board, administers the Virginia Pesticide Control Act, overseeing
pesticide licensing, product registration, applicator certification, and compliance enforcement.
Question 2: Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), how is a
'Restricted Use Pesticide' (RUP) classified?
A) A product available for purchase and application by the general public without training.
B) A product that may cause unreasonable adverse environmental or health effects unless
applied by or under the direct supervision of a certified applicator.
C) A product exempt from all EPA registration requirements under Section 25(b).
D) A chemical approved exclusively for municipal water treatment facilities.
Correct Answer: B) A product that may cause unreasonable adverse environmental or
health effects unless applied by or under the direct supervision of a certified applicator.
Rationale: FIFRA classifies a product as a Restricted Use Pesticide (RUP) when its potential
hazards to human health or the environment require that purchase and application be
restricted exclusively to certified applicators or persons under their direct supervision.
, Question 3: Which signal word on a pesticide label indicates the highest level of acute oral, dermal,
or inhalation toxicity, requiring the word 'POISON' and a skull and crossbones symbol in red?
A) CAUTION
B) WARNING
C) DANGER-POISON
D) NOTICE
Correct Answer: C) DANGER-POISON
Rationale: The signal word 'DANGER-POISON' accompanied by the skull and crossbones
symbol denotes EPA Toxicity Category I (highly toxic), indicating that a tiny dose (a few drops
to a teaspoonful) can be fatal if ingested, inhaled, or absorbed.
Question 4: What measure represents the estimated dose of a chemical required to kill 50 percent
of a test population of laboratory animals through oral or dermal exposure?
A) LC50
B) Parts per million (PPM)
C) Volatilization index
D) LD50 (Lethal Dose 50)
Correct Answer: D) LD50 (Lethal Dose 50)
Rationale: LD50 (Lethal Dose 50) measures acute oral or dermal toxicity in milligrams of
chemical per kilogram of body weight (mg/kg) required to kill 50% of a test population. A
lower LD50 numerical value indicates higher chemical toxicity.
Question 5: Which route of body exposure accounts for the vast majority (over 90 percent) of all
occupational pesticide exposure incidents among chemical handlers and applicators?
A) Dermal exposure (skin absorption).
B) Oral ingestion.
C) Ocular absorption.
D) Direct intravenous injection.
Correct Answer: A) Dermal exposure (skin absorption).
Rationale: Dermal exposure through skin absorption is the primary pathway for occupational
pesticide exposure, occurring during mixing, loading, equipment calibration, application, and
equipment maintenance.
Question 6: According to the EPA Worker Protection Standard (WPS), what is the mandatory
Restricted-Entry Interval (REI) listed on a pesticide label?
A) The period during which the product must remain stored in a locked container.
B) The specified duration of time that must pass after a pesticide application before workers
can enter the treated area without protective equipment.
C) The timeframe required for a pesticide container to be triple-rinsed.
D) The maximum allowable shelf life of an opened chemical concentrate.
