Sonar A. S. Aquatic Herbicide is a fluridone-based formulation for the management of aquatic vegetation in freshwater ponds, lakes and reservoirs. Sonar A. S. Aquatic Herbicide is a highly effective aquatic herbicide used to selectively manage undesirable aquatic vegetation in freshwater ponds, lakes, reservoirs, rivers and canals.
Sonar A. S. Aquatic Herbicide will remove unwanted weeds from your lake or pond for a year or longer with a single treatment. No other aquatic herbicide on the planet is more effective on duckweed, period. Unlike other aquatic herbicides, Sonar has no restrictions on water use after application. Swimmers can still swim. Fisherman can still fish. Livestock can still drink.
Sonar A. S. Aquatic Herbicide is absorbed through the leaves, shoots, and roots of susceptible plants, and destroys the plant by interfering with its ability to make and use food.
