Many pond owners consider duckweed to be their toughest aquatic weed problem. Duckweed is a very common nuisance aquatic weed that is spread from pond to pond via waterfowl or other wildlife. While it is commonly mistaken for algae, duckweed is actually a tiny plant with an explosive reproductive capacity that can completely cover a pond in just a few weeks to the point that the infested water body resembles a golf-course green. No other aquatic herbicide is more effective on duckweed. Sonar provides complete, long-lasting control of duckweed and other stubborn unwanted aquatic vegetation.
