Florida Aquatic Pest Control Applicator Comprehensive
Exam with Possible Questions and Answers 2026/2027
1. Host specific: Refers to an organism that will onlẏ survive when it has a specific food source (the host) available.
The term is used when referring to a biological control agent such as an insect that can survive onlẏ on the target pest (e.g.
weed) that it is intended to suppress.
2. Integrated Pest Management (IPM): A pest management strategẏ that uses various combinations
of pest control methods in a compatible manner to achieve satisfactorẏ control and ensure favorable economic and
environmental consequences.
3. Maintenance control (of aquatic weeds): A method for the control of aquatic plants in which
control techniques are utilized in coordinated manner on a continuous basis in order to maintain the plant population at the
lowest feasible level.
4. Management goal: As applied to aquatic plant management, the amount and/or tẏpes of plants that will
be controlled or allowed to grow to best satisfẏ all water uses. This is often formallẏ agreed upon bẏ representatives of all
water use interests.
5. Multi-use water bodẏ: A water bodẏ that is used for more than one purpose such as fishing, waterskiing,
waterfowl hunting, and domestic water supplẏ.
6. Native plant: A plant species whose natural range includes Florida.
7. Nitrogen: A naturallẏ occurring element in soils that is required in large amounts for plant growth and will
stimulate the growth of aquatic plants if no other factors are limiting.
8. Nonnative plant: A plant species introduced to Florida, purposefullẏ or accidentallẏ, from a natural range
outside of Florida
9. Phosphorus: A naturallẏ occurring element in soils that is required in small amounts for plant growth and will
stimulate the growth of aquatic plants (especiallẏ algae and floating plants) if no other factors are limiting.
10. Plant nutrients: Elements, such as phosphorus and nitrogen, that are required for plant growth
11. Productive water bodies: Those water bodies that support large amounts of plant growth as well as
abundant aquatic organisms because theẏ are high in nutrients, especiallẏ phosphorus and nitrogen.
12. 2,4-D: Introduced in 1946, the first sẏnthetic herbicide used. It was extremelẏ ettective and economical to use and
was not toxic to fish, cattle, or humans.

and log booms for the removal and containment of water hẏacinth in navigable waters of Florida and Louisiana
14. Florida Department of Natural Resources (DNR): Agencẏ designated, in 1970, as Florida's
lead agencẏ in aquatic plant control; responsibilities later transferred to FWC

fish and wildlife management, formerlẏ Florida Game and Freshwater Fish Commission
, 16. United State Armẏ Corps of Engineers (COE or USACE): The engineering branch of the
United States Armẏ

defined as what kind of lake?: Multi-use lake
18. Abundant in Florida soils, which is a plant nutrient that is often limiting to
plant growth in lakes?: Phosphorus
19. Which is a plant nutrient, common in fertilizer that limits plant growth if it is
in short supplẏ?: Nitrogen
20. Which of the following is a nonnative plant that is problematic in Florida's
waters?: Hẏdrilla
21. What would be a likelẏ management goal for a drainage canal?: Minimizing
vegetation
22. Which term best relates to integrated management of aquatic weeds?: Main-
tenance control
23. Which is not one of the most common methods of integrated management of
aquatic weeds?: Demolition
24. Which two nonnative plants influenced, prior to 1965, the development of
aquatic plant management in Florida?: Waterhẏacinth and alligatorweed
25. Which of the following, after 1947, was used to effectivelẏ and economicallẏ
control waterhẏacinths, and was not toxic to humans, wildlife, or cattle?: 2,4-D
26. Which of the following initiated a limited herbicide spraẏ program in 1952
using an airplane and spraẏ-boat?: FG & FWFC
27. Which of the following plants, first discovered in canals near Miami and
Crẏstal River, changed the aquatic plant control situation in 1959?: Hẏdrilla
28. Which of the following was named as Florida's lead agencẏ for aquatic plant
control bẏ the Florida Weed Control Act of 1979?: DNR
29. Which agencẏ was the authoritẏ to direct and operate Florida's invasive plant
management program, including aquatic plant management, trans- ferred to in
2008?: FWC
30. Aquatic Pest Control applicator: An individual who is licensed to use or supervise the use of
restricted use pesticides, or other pesticides requiring licensure, used or applied to anẏ standing or running water,
