1. The primary objective of aquatic pest control is to:
A. Eliminate all plant life
B. Maintain ecological balance
C. Increase water turbidity
D. Promote algae growth
ANSWER: B
Rationale: Aquatic pest control focuses on managing pests while preserving the
ecological balance of the water body.
2. Which factor most directly influences herbicide selection for aquatic use?
A. Air temperature
B. Water depth and flow
C. Soil compaction
D. Wind direction
ANSWER: B
Rationale: Water depth and flow affect herbicide dispersion, concentration, and
effectiveness.
3. An applicator treating an irrigation canal must be especially cautious about:
A. Sunlight intensity
B. Downstream water use
C. Fish migration
D. Sediment type
,ANSWER: B
Rationale: Treated water may be used downstream for crops, livestock, or
drinking, requiring strict label compliance.
4. Which aquatic plant is classified as a submerged species?
A. Water hyacinth
B. Duckweed
C. Hydrilla D. Cattail
ANSWER: C
Rationale: Hydrilla grows entirely below the water surface, classifying it as
submerged.
5. Floating aquatic plants primarily reproduce by:
A. Spores
B. Tubers
C. Rhizomes
D. Vegetative fragmentation
ANSWER: D
Rationale: Many floating plants spread rapidly through vegetative fragmentation.
6. Dissolved oxygen depletion after herbicide treatment is most likely caused
by:
A. Chemical toxicity
B. Plant decay
C. Increased salinity
D. Water stratification
ANSWER: B
Rationale: Decaying plant material consumes oxygen during decomposition.
7. Which organism is commonly targeted in aquatic mosquito control?
, A. Adult mosquitoes
B. Mosquito larvae
C. Dragonflies
D. Water beetles
ANSWER: B
Rationale: Larval control is more effective and environmentally sound than
targeting adults.
8. When applying pesticides near potable water sources, applicators must
follow:
A. Federal Aviation Regulations
B. Restricted entry intervals
C. Drinking water setback requirements
D. Worker housing rules
ANSWER: C
Rationale: Setback requirements protect drinking water from contamination.
9. Emergent aquatic plants are best described as plants that:
A. Float freely
B. Grow entirely underwater
C. Are rooted with foliage above water
D. Grow only in saline water
ANSWER: C
Rationale: Emergent plants are rooted underwater with stems and leaves above the
surface.
10. Which method provides the most selective aquatic weed control?
A. Mechanical harvesting
B. Chemical control
