Durvet AquaVet Shoreline Weeds is a landscape and aquatic herbicide designed to control emergent shoreline weeds, including cattails, water lilies, and other vegetation. Apply when weeds are actively growing, using 1.5 oz per gallon of water plus 2 tsp/gallon of non-ionic surfactant to improve uptake. One quart makes up to 25 gallons of spray solution, treating up to 10,000 sq ft (¼ acre) of target weeds. Non-selective and effective to the root, it safely controls shoreline weeds while remaining safe for fish, waterfowl, swimming, and livestock.
