AQUATHOL Super K Granular is a convenient ready-to-use granular product. Nothing to mix or spray. Begins working on contact with submersed weeds to break down cell structure and inhibit protein synthesis. Without this ability the weed dies.
Initial results in 1 to 3 days. Full kill takes place in 1 to 2 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 when waters are 65ºF or above, 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. of shoreline.
