  5. 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
    • Effective against various aquatic weeds, including bladderwort, hydrilla, pondweed, water milfoil, duckweed, mosquito fern, and paragrass

    Cannot sell to the following states: California, Connecticut, Maine, New Jersey, New York, Oregon, Washington

  6. Sonar Q Pellets 8Lb Pail L00366

    Sonar Q Pellets 8Lb Pail L00366

    $329.97

    Sonar Q is a selective systemic aquatic herbicide to control the growth of aquatic vegetation in lakes, reservoirs, fresh water ponds, and drainage canals.

    Sonar Q pellets are less concentrated and easier to use than Sonar AS liquid (also available through Rural King).

    Sonar AS is a 5% Fluridone product which inhibits the formation of carotene, degrading the chlorophyll necessary for photosynthesis and plant energy production.

    • For best results, apply prior to initial growth or at beginning of active growth.
    • Effectiveness reduced in rapidly moving water or conditions which dilute the concentration of Sonar Q. Contact must be maintained for 45 days for effective treatment. Symptoms of affected plants include white and pink foliage growth.
    • Effectively controls coontail, fanwort, bladderwort, naiads, elodea, hydrilla, watermilfoil and many pond weeds. For a complete list of plants controlled by Sonar Q, see label.
    • Follow all label guidelines and warnings.
    • Permits may be required prior to use of this product, consult with local water authorities.
    • Harmful if absorbed through skin, inhaled, or swallowed.
    • Not for use in drinking, fishing, swimming, or water for livestock or pet consumption.
    • Not for use in hydroponic farming, or in water for irrigating nursery or greenhouse plants.
    • Do not use any type of irrigation system for application.

    2.5 to 5 pounds per surface acre. Consult label for complete application and dosing instructions.

  7. 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

  9. Habitat Herbicide 2.5 Gal L00174

    Habitat Herbicide 2.5 Gal L00174

    $319.97

    Application of Habitat herbicide can only be made by federal or state agencies, or those applicators that are licensed or certified as aquatic pest control applicators and are authorized by the state and local government. Applications may only be made for the control of undesirable emergent and floating aquatic vegetation in and around standing and flowing water, including estuarine and marine sites. Applications can be made to control undesirable wetland and terrestrial vegetation growing in or around surface water when applications may result in inadvertent application to surface water. Proper application and timing should lead to longer control of undesirable species than found with other methods of emergent plant control. The use of a non-ionic surfactant is required with the use of Habitat.

  10. 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.


    Key Features:

    • 40lb container
    • 5% fluridone
    • Ready-to-use pelleted formula
    • Effective against various aquatic weeds, including elodea, hydrilla, water milfoil, naiads, and paragrass
