Texas Aquatic Pest Control Exam Review with
Answers and Rationales | 100% Pass Guaranteed
| Graded A+
1. The primary goal of aquatic pest control is to:
A. Eliminate all aquatic plants
B. Increase fish populations
C. Manage pests while protecting water quality and non-target
organisms
D. Remove all algae
Aquatic pest management focuses on balance and environmental
protection, not total elimination.
2. Which agency regulates pesticide use in Texas?
A. EPA only
B. Texas Parks and Wildlife
C. Texas Department of Agriculture (TDA)
D. USDA
TDA administers pesticide licensing and enforcement within Texas.
3. A pesticide label is:
A. A suggestion
B. Optional guidance
C. A legal document
D. Only for manufacturers
Using a pesticide contrary to its label is a violation of federal and
state law.
,4. Which type of aquatic plant grows entirely underwater?
A. Emergent
B. Floating
C. Submersed
D. Shoreline
Submersed plants grow completely below the water surface.
5. Which of the following is an emergent plant?
A. Hydrilla
B. Duckweed
C. Cattail
D. Coontail
Emergent plants are rooted underwater but extend above the
surface.
6. Excess nutrients in water most often cause:
A. Fish sterilization
B. Algal blooms
C. Water clarity improvement
D. Reduced plant growth
Nutrient enrichment (eutrophication) stimulates excessive algae
growth.
7. The term “eutrophication” refers to:
A. Water sterilization
B. Chemical contamination
C. Nutrient enrichment leading to excessive plant/algae growth
D. Fish disease
, High nutrient levels accelerate aquatic plant and algae growth.
8. Which factor most affects herbicide effectiveness in water?
A. Wind speed
B. Soil pH
C. Water temperature
D. Air humidity
Plant metabolism and herbicide activity increase with warmer
temperatures.
9. Dissolved oxygen levels are lowest:
A. Midday
B. Afternoon
C. Early morning
D. Evening
Respiration overnight reduces oxygen until photosynthesis resumes.
10. Fish kills after treatment usually result from:
A. Herbicide toxicity
B. Oxygen depletion from decomposing plants
C. Water warming
D. Fish migration
Large plant die-offs increase decomposition, consuming oxygen.
11. Integrated Pest Management (IPM) emphasizes:
A. Chemical-only control
B. No control methods
