  3. Navigate 50lb  L00403

    Navigate 50lb L00403

    $190.97

    If you own a body of water, you know that aggressive aquatic weeds can quickly become troublesome. Watershield, coontail, spatterdock, stargrass, water lilies, and especially the invasive Eurasian water milfoil all contribute to clogged intakes, flooding problems, and stagnant mats. Such overgrown vegetation can also rob the water of oxygen and increase sedimentation rates.

    With Navigate, you have a strong ally. This granular aquatic herbicide targets and destroys some of the most persistent water weeds. Works as both a herbicide and a growth regulator for coontail, spatterdock, and milfoil. Helps suppress other species of difficult aquatic plants, including yellow water lily and bladderwort. The formula’s heat-treated attaclay granules not only decompose slowly to provide extended control, they also sink quickly to get right to the root of the problem.

    Navigate Granular Herbicide should not be used in domestic or livestock water supplies. Nor should this product be used in water sources for agricultural sprays or irrigation systems. Application rates vary. One-hundred pounds per acre is recommended for treating milfoil. A maximum of 200 pounds per acre is recommended for resistant plants such as watershield and spatterdock. For best results, use in the spring and early summer. A second application may be necessary in areas of heavy regrowth or for sections that border untreated areas.

    Key Features:

    • 50 lb. bag
    • 2,4-Dichlorophenoxyacetic acid, dimethylamine salt 46.8%
    • Herbicide and growth regulator for coontail, spatterdock, and milfoil
    • Helps suppress other species, including water lilies and bladderwort
    • Gradual release formula

  4. Sonar One 20lb L00371

    Sonar One 20lb L00371

    $680.97

    Sonar, the world’s leading brand of aquatic herbicide, now brings you SonarOne. Just one treatment is often all you need to treat your pond, lake, drainage canal, or reservoir. This pelleted formula treats all three forms of problematic aquatic weeds: floating, emergent, and submersed. Whether you’re combating duckweed, paragrass, bladderwort, water milfoil, or a host of others, SonarOne is the only herbicide you need.

    SonarOne restricts the formation of carotene in the targeted plants. When carotene is absent, chlorophyll is quickly destroyed by the sunlight. Within days, you will see results. For optimal outcome, apply early in the season before or soon after difficult weeds start to appear. Applying early ensures the best season-long control.

    SonarOne carries no restrictions on the recreational use of waterways following treatment. Fourteen to 30 days restriction applies to using treated water for irrigational purposes following application. See manufacturer’s instructions for details. Application rates vary based on plant species. SonarOne is non-corrosive to application equipment.

    Key Features:

    • 20lb container
    • Pelleted formula
    • 5% fluridone

  5. Sonar Q 40lb Granular L00362 Aquatic Herbicide

    Sonar Q 40lb Granular L00362 Aquatic Herbicide

    $1,330.97

    Vegetation is essential for maintaining thriving pond ecosystems. Aquatic vegetation provides oxygen, food, and habitat for wildlife. Their root systems are vital to stabilizing sediment layers. However, it doesn’t take long for these benefits to be counteracted by the overgrowth of problematic and invasive species of pond weeds. Bladderwort, elodea, hydrilla, water milfoil, paragrass, and naiads, just to name a few, can all make your pond an eyesore and unusable for recreation. With Sonar Q, you have a fast, effective, and cost-efficient ally.

    This pelleted formula is specially designed to be fast-releasing yet long- lasting. And because it is in a pelleted form, you can expect the same results as from a liquid but with better application control with no worry of overspray. In fact, Sonar Q offers better and longer lasting residual treatment than the leading liquids. The unique pellets immediately carry the active ingredient to the base of the plant, where it is most efficient and least likely to be degraded by light.

    Sonar Q is especially recommended for ponds with rocky or sandy bottoms. For best results, it is best to apply in the early spring at the first sign of growth. Application rates for Sonar Q pellets vary from 3.2 - 25 pounds per acre for ponds to 4 - 80 pounds per acre for lakes. There are no restrictions on swimming or fishing following treatment. See manufacturer’s label for details.
