Virginia Commercial Pesticide Applicator Category 5A Aquatic Pest Control Surface Water
Certification Examination
Question 1
Which statement best explains why accurate identification of aquatic vegetation before
selecting an herbicide is considered one of the most important responsibilities of a Virginia
Category 5A aquatic pesticide applicator?
A. Every herbicide controls all aquatic plants equally well.
B. Correct identification helps ensure effective, legal, environmentally responsible treatment
while minimizing unnecessary pesticide applications.
C. Plant identification is only necessary for invasive species.
D. Herbicides are selected primarily according to water depth rather than target species.
Answer: B
Rationale: Proper plant identification ensures the selected pesticide is labeled for the target
species and reduces environmental impacts.
Question 2
Before applying an aquatic herbicide to a public reservoir that supplies drinking water, which
information should always be verified to ensure compliance with pesticide label requirements?
A. The boat registration number
B. Drinking water restrictions, dosage limitations, and any applicable setback or intake
restrictions
C. The age of surrounding trees
D. Local fishing tournament schedules only
,Answer: B
Rationale: Labels specify restrictions protecting drinking water supplies and must always be
followed.
Question 3
Which aquatic plant classification includes species that are rooted in bottom sediments while
producing leaves and flowers that float on the water surface?
A. Emergent plants
B. Floating-leaved plants
C. Free-floating plants
D. Submerged plants
Answer: B
Rationale: Floating-leaved plants are rooted but have leaves that rest on the water surface.
Question 4
Why is dissolved oxygen monitoring particularly important following treatment of dense
aquatic vegetation with herbicides?
A. Herbicides immediately increase oxygen concentrations.
B. Decomposing vegetation may reduce dissolved oxygen levels enough to stress or kill fish.
C. Dissolved oxygen only affects algae.
D. Oxygen concentration has no relationship to aquatic herbicide applications.
Answer: B
Rationale: Plant decomposition consumes oxygen, potentially causing fish kills.
, Question 5
According to pesticide label requirements, what document serves as the primary legal authority
governing how an aquatic pesticide may be applied?
A. Product advertisement
B. Equipment manual
C. EPA-approved pesticide label
D. Manufacturer's brochure
Answer: C
Rationale: The pesticide label is a legally enforceable document.
Question 6
Which application method is generally most appropriate for controlling submerged aquatic
vegetation growing several feet below the water surface?
A. Broadcast aerial dusting
B. Subsurface injection or evenly distributed aquatic application
C. Spot painting
D. Soil incorporation
Answer: B
Rationale: Subsurface applications place herbicide where submerged weeds actively grow.
