Works rapidly enough to be effective in both still and slow moving water.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.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 as water temperature warms to 65° F and 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. Although selective, Aquathol® Super K Granular is effective on many different weedsRecommended application rates for Aquathol® Super K Granular range from 0.5 to 5.0 ppm. Safe for most fish at 100 ppm or more. For most Pondweeds growing in lakes 2.0 to 4.0 ppm will give excellent control. This rate is equivalent to 0.8 to 1.6 lbs. of Aquathol® Super K Granular per 1,000 sq. ft. at an average depth of 4 feet. Adjust these quantities of material up or down depending on average depth. At a 6 ft. average depth use 50% more material per 1,000 sq. ft. When treating an entire pond you can use 25% to 50% less material and still achieve excellent control. To apply Aquathol® Super K Granular, simply broadcast uniformly over the water surface by hand or use a spreader (LMI992402 or LMI992403). Heavy infestations should be treated in sections 5 to 7 days apart to avoid oxygen depletion.Water treated with Aquathol® Super K Granular should not be used for irrigation, human or animal consumption for 7 days.
