with answers \|




1.Host specific: refers to an organism that will only survive when it has
\| \| \| \| \| \| \| \| \| \| \| \| \




a specific food source (the host) available - term is used when referring
\| \| \| \| \| \| \| \| \| \| \| \| \




to a bioagent that can survive only on the target pest it is intended to
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \




suppress
2.Integrated Pest Management (IPM): a pest management strategy that \| \| \| \| \| \| \| \| \|




uses various combinations of pest control methods in a compatible
\| \| \| \| \| \| \| \| \| \|




manner to achieve sat- isfactory 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 a coordinated
\| \| \| \| \| \| \| \| \| \| \|




manner on a contin- uous 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 types of plants that will be controlled or allowed to grow to
\| \| \| \| \| \| \| \| \| \| \| \| \|




best satisfy all water uses;
\| \| \| \| \| often \| formally \| agreed \| upon \| by
representatives of all water use interests \| \| \| \| \|




5.Multi-use water body: a water body that is used for more than one
\| \| \| \| \| \| \| \| \| \| \| \| \




purpose such as fishing, waterskiing, waterfowl hunting, and domestic
\| \| \| \| \| \| \| \| \




water supply \|




6.Nitrogen: a naturally 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

,7.Phosphorous: a naturally occurring element in soils that is required in \| \| \| \| \| \| \| \| \| \| \|




small amounts for plant growth and will stimulate the growth of aquatic
\| \| \| \| \| \| \| \| \| \| \| \|




plants (especially algae and floating plants) if no other factors are
\| \| \| \| \| \| \| \| \| \| \|




limiting
8.Plant nutrients: elements, such as P and N, that are required for plant
\| \| \| \| \| \| \| \| \| \| \| \| \|




growth
9.Productive water bodies: those water bodies that support large amounts \| \| \| \| \| \| \| \| \| \|




of plant growth as well as abundant aquatic organisms because they
\| \| \| \| \| \| \| \| \| \| \|




are high in nutrients, especially P and N
\| \| \| \| \| \| \|




10.2,4-D: introduced in 1946, the first synthetic herbicide used.
\| \| \| \| \| \| \| \| \|




Extremely effective (water hyacinth) and economical to use and was not

toxic to fish, cattle, or humans
\| \| \| \| \|




11.River and Harbor Act of 1899: federal legislation that authorized

and containment of water hyacinth in navigable waters of Florida and
\| \| \| \| \| \| \| \| \| \| \|




Louisiana
12.Florida Department of Natural Resources (DNR): agency designated in
\| \| \| \| \| \| \| \| \




1970 as Florida's lead agency in aquatic plant control; responsibilities
\| \| \| \| \| \| \| \| \| \




later transferred to FWC

recreational ponds, permitted water retention ponds, and \| \| \| \| \| \| \|




aquaculture production ponds) \| \|




16.Canals and surface water retention ponds: predominantly serve for
\| \| \| \| \| \| \| \| \|




storage and movement of water to prevent flooding; provide
\| \| \| \| \| \| \| \| \|




secondary benefits such as fishing, aesthetics (aquascaping), wildlife

on?: control of water hyacinth and hydrilla
\| \| \| \| \| \|




21.How are management goals often determined?: type of water body
