Catt Plex is not labeled for American pond weed. We would recommend SePRO Sonar RTU Aquatic Weed Herbicide is a specially formulated aquatic herbicide that’s designed to help control troublesome weeds in ponds. It’s very easy to use, simply pour it directly into the water from the shoreline without the need for boat or spray equipment and it also doesn’t require any mixing. There are NO fishing, swimming, livestock and pet consumption restrictions for Sonar RTU.
