Section 3 introduces the tools, or individual methods, devices, products, etc., that are available to control aquatic plants in Florida waters. There are four general categories: biological, physical (also called cultural), chemical, and mechanical.  

Some of these methods are broad spectrum in their activity meaning they will control many (or all) plants species; for example, mechanical harvesters or shredders. Others are extremely selective like insect species researched and approved for release to control only one species, or one part, of an aquatic plant. 

Basic information, including a brief history is presented for the four categories of aquatic plant control tools. Links to specific information on registration procedures and protocols is are provided for biological and chemical controls.
