SePRO Sonar® A.S. Herbicide



SePRO Sonar A.S. Herbicide is a specialized herbicide that controls almost all aquatic weeds in ponds and lakes. This 41.7% fluridone product acts as a selective systemic aquatic herbicide for management of aquatic vegetation in fresh water ponds, lakes, reservoirs, drainage and irrigation canals. It is absorbed by plants, which inhibits the weed's ability to make food, causing it to die.
  • Very effective on duckweed and milfoil
  • Each 32oz treats up to 1 acre
  • Initial results possible within 10 days
Application Instructions
Sonar should be applied early in the season, prior to or just after plant growth begins. Refer to manufacturer's label for exact dosage rates and instructions. Maintain the recommended concentration in contact with the target plants for a minimum of 45 days. Initial results can be seen in as few as 10 days, but a complete kill can take 30-90 days. Treatments may need to last for several seasons in many cases, depending on plants.
