ALLIED HERBICIDES

The following products are specialty water treatments that control a wide variety of aquatic plants.  While the purchase price initially appears high on products like Sonar and Avast, the fact that they treat a wide range of plants (often eliminating the need for multiple chemicals) and the fact that they often provide multiple years of control, makes them the best choice in many applications.

Hydrothol is a granular herbicide that is fast acting and effective on a variety of aquatic weeds including milfoil, coontail, hydrilla, sago pondweed, leafy pondweed, curly leaf pondweed and others.  Hydrothol should only be used for spot treating.  Use Aquathol, below, early in the season when plants are young and easier to treat.  Slight water restrictions (check them here).

Aquathol Super K is a granular herbicide that utilizes Culigel® super absorbent polymer technology.  Aquathol Super K is six times more concentrated than regular Aquathol.  This means less product to handle, less labor to apply and reduced container disposal.  Excellent for spot treatment of hydrilla, pondweed and Eurasion milfoil.  Dosage rate is variable according to plant species.  Available in granular form in 10 pound and 25 pound containers or in 2.5 gallon liquid form.

Reward Concentrated is a concentrated aquatic herbicide that's been proven on a wide variety of aquatic plants including milfoil, cattails, duckweed, pondweed and others (check here).  This liquid herbicide is applied by sprayer and should not be applied to turbid waters.  There is very little risk of environmental damage since Reward's concentration rapidly decreases as it is absorbed into the aquatic vegetation.  Reward is a restricted use pesticide in the state of Michigan.  A copy of your pesticide applicators license must be faxed to us before we can sell to anyone in Michigan.  All other states are not restricted and can be shipped without certification.  Application rate is one to two gallons per acre.  Should be used with activator for best results.

Sonar is a specialty herbicide that controls almost all aquatic weeds.  Sonar should be applied early in the season, prior to or just after plant growth begins.  Very effective on duckweed and milfoil.  Treatments last for several seasons in many cases.  Sonar is absorbed by the plants and inhibits the weed's ability to make food, causing it to die.  Initial results can be seen in ten days.  Complete kill can take 30 to 90 days.
