UF-IFAS Extension publication SS-AGR-44 is a quick reference to the effectiveness of herbicide active ingredients for controlling common aquatic weeds. Sensitivity of the target weed to the active ingredient is only one consideration in choosing the appropriate herbicide product. Other factors that may be important in such a decision include water uses, other plant species present, toxicity to fish and other organisms, and additives in individual products. Specific product information should be obtained by consulting the product labels; label instructions must be followed for any lawful herbicide application.
