This reference guide defines the parameters considered by aquatic plant managers and FWC biologists when formulating a management plan using herbicides in Florida waters. No single herbicide is appropriate for controlling all invasive or nuisance aquatic plant infestations. Therefore, aquatic plant managers must have a thorough understanding of how each herbicide acts in Florida aquatic […]

The FWC Invasive Plant Management Section has invested significantly in research through the years on biological, mechanical, and physical means to control aquatic plants, used alone or in combination, to augment or replace herbicide use. Additionally, much research has been conducted to understand the physiology and growth patterns of target invasive plants in Florida waters […]

Fishermen, boaters, swimmers and others often question the need for, and safety of, weed control programs. Following are a few of the most frequently asked questions and answers regarding Florida's aquatic plant management program. Are aquatic herbicides safe to use? All herbicides should be handled with great care, especially in their concentrated form. Once diluted […]
The goal of plant managers is almost always to control invasive plants without harming the native plants that grow in the same area. To accomplish this, they must apply registered aquatic herbicides selectively. Professional managers perform selective applications through use of specially formulated herbicides, seasonal applications, selective methods, and varying concentrations. Selective Herbicides Several herbicides […]
There are fourteen active ingredients (chemical compounds) approved for use in Florida waters as of 2011. These active ingredients may be formulated and sold under various trade names such as Aquathol, Rodeo and Sonar. They are applied directly to the target plant or dispersed within the water for the purpose of treating invasive weeds. These […]
