Nothing to mix or spray. Begins working on contact with submerged weeds to break down cell structure and inhibit protein synthesis. Without this ability the weed dies. Full kill takes place in 3 to 4 weeks. As weeds die they drop to the bottom and decompose.
Effective anytime live weeds can be contacted. Best results occur when applied in spring and summer as water temperature rises to 65 degrees Fahrenheit or warmer. With early treatment, less material is required and a longer weed-free period will result.
Contact time with weeds should be at least 2 hours. In large bodies of water, longer-term control will result when treating a minimum of 1 acre or 100 ft. Although selective, Aquathol Super K Granular is effective on many different weeds.
