Aquatic Endothall Herbicides

Endothall is one of the most versatile and effective aquatic herbicides ever developed.  It’s an excellent Aquatic Habitat Management tool that can provide season long control of a broad spectrum of submerged weeds often found in small lakes and ponds.  Endothall is not toxic to fish or other aquatic organisms, and has a relatively short half-life in the water.  

Endothall provides control of aquatic weeds in a relatively short time, generally 3-4 weeks, and can provide long-term control depending on the application timing and the target species.
