Hydrothol Granular Herbicide – 20 lb.
Hydrothol Granular Herbicide – 20 lb. is a selective, rapid-acting, contact herbicide and algaecide. Controls submersed weeds and algae in lakes, ponds, irrigation canals, and drainage ditches. Works rapidly enough to be effective in both still and slow moving water. May be harmful to fish at recommended application rates.
Aquathol with a boost!
The physical form, mode of action, and general usage of Hydrothol Granular are similar to Aquathol Super K Granular. Where fish are present, application of Hydrothol Granular at rates over 1.0 ppm should be used only for spot treatments, narrow margins, or where some fish kill is acceptable. Do not treat more than 10% of a lake or pond at one time at application rates above 1.0 ppm.
When treating lakes or ponds with Hydrothol Granular, begin at shoreline and work toward center. Apply parallel to the shoreline. This will herd fish away from the treated area into deeper, untreated portions of the lake or pond.
Treat your entire pond for algae
Lakes and Ponds:
Algae can be controlled with as little as 0.2 ppm of Hydrothol Granular when the entire pond is treated. For longer term control or spot treatments, use 0.5 to 1.5 ppm. Repeat treatment when growth reappears. For floating mats, scatter uniformly over the surface of the mat.
Weeds can be controlled with 0.5 to 3.0 ppm of Hydrothol Granular. For most Pondweeds 1.0 to 2.0 ppm will give excellent control. When treating an entire pond you can use 25% to 50% less material.
Canals and Ditches
Irrigation canals or drainage ditches will require 3.0 to 5.0 ppm of Hydrothol Granular.
Treat heavy infestations in sections of 1/3 to 1/2 of the total weed volume to avoid oxygen depletion. Allow 5 to 7 days before continuing to untreated sections.
Water in areas treated with Hydrothol Granular should not be used for irrigation or human consumption for 7 to 25 days, depending on the application rate.
