Coontail is a submersed aquatic plant and can be easily identified by the "raccoon tail" cluster of leaves at the end of the main stalk. It has slender stems and leather-like leaves. Coontail is called hornwort when it is sold for aquarium decorations. It then spreads into ponds after aquariums are dumped into water bodies.
Other Names: Hornwort
Pond Dye can be used to limit sunlight into the pond. With reduced sunlight, photosynthesis cannot occur so growth will be stunted.
There are several options to control Coontail:
- Use a season long herbicide such as Sonar™ A.S.. One treatment treats duckweed and many other common pond weeds for the season.
- Use a broad spectrum contact herbicide, such as Ultra PondWeed Defense®, will quickly kill duckweed. Because it does not stay in the water body, multiple treatments may be needed throughout the season.
- Use Clipper™, a fast and selective herbicide that controls tough invasive and nuisance aquatic plants.
Chemical Application Best Practices
Anytime you use chemicals treat weeds and algae, please keep in mind the following:
- Treat your pond in sections. Treat only half the pond's surface at a time, if the weather is hot, only treat 1/4-1/3 of your pond. Wait 10-14 days between treatments.
- Once the weeds have browned, use a rake to remove as much dead material as possible. This prevents an accumulation of dead plant material and muck.
- Treat your pond with the proactive approach to pond management. Use PondClear™, MuckAway™ and Pond Dye to keep your pond looking great.
