Aquatic Weed Management: Herbicide Safety, Technology and Application Techniques [Image: Herbicide Safety, Technology and Application Techniques] Aquatic herbicides are chemicals used to kill aquatic plants or severely interrupt their growth. About 200 herbicides are registered by the EPA for use in the United States, but only six are labeled for use in aquaculture sites. It is important that aquaculturists use these registered herbicides in a safe and effective manner. Aquatic Weed Management: Herbicides [Image: Herbicides] Herbicides are just one method of managing aquatic weeds. There are also: 1) preventive methods such as proper pond site selection and construction, fertilization andperiodic draw-downs; 2) biological methods such as grass carp (Ctenopharyngodon idella); and 3) mechanical methods such as cutting, seining and raking. Using a combination of methods is the most effective method of managing aquatic weeds. Using Grass Carp in Aquaculture and Private Impoundments [Image: Using Grass Carp in Aquaculture ] Grass carp can effectively control aquatic vegetation, particularly submerged vegetation. The key to using grass carp is to stock the proper number based on their vegetation preferences, the water temperature, and the biomass and pond coverage of the plants.
