Virginia Category 3A Exam Practice (Batch 1: 1–50)
1. A technician applies a pesticide but ignores label restrictions on application timing near blooming
ornamentals. What violation occurred?
A. Minor procedural error without legal consequence
B. Proper IPM compliance decision
, Page 3 of 132
C. Violation of FIFRA “label is the law” requirement
D. Acceptable deviation under field conditions
Answer: C
Rationale: Pesticide labels are legally binding under FIFRA, and ignoring bloom restrictions violates
federal law.
2. A landscaper applies a restricted-use pesticide without direct supervision of a certified applicator.
What is the main compliance issue?
A. Correct delegation under WPS rules
B. Illegal application under restricted-use pesticide supervision requirements
C. Acceptable training exception
D. Standard operational flexibility
Answer: B
Rationale: Restricted-use pesticides require certified applicator supervision for legal compliance.

3. A worker develops skin irritation after mixing pesticide without gloves or protective clothing. What
exposure route is most likely responsible?
A. Dermal exposure through skin absorption
B. Inhalation through lungs
C. Oral ingestion through mouth
D. Ocular exposure through eyes
Answer: A
Rationale: Skin contact during mixing is a primary dermal exposure pathway.
4. A pesticide label states “REI 12 hours,” but workers re-enter after 6 hours. What is the correct
interpretation?
A. REI is optional guidance
B. Workers can re-enter early if dry
