Pond Weed Control

Recommended As The Safest Weed Control Treatment

Following our philosophy of using the safest possible treatments available for pond problems, we now recommend using Hydrothol or Aquathol to treat rooted pond weed species.

Unlike algae and duckweed, which derive their support directly from the water, rooted plant species should not be treated with our Healthy Ponds Aquasphere products. Instead it's best to treat them with a recommended herbicide for the best results.

We recommend the two products below because they can be used for spot treating a pond. This limits their impact on the pond as a whole, and allows a highly targeted approach to the problem weeds. Both products are contact herbicides, meaning they must make contact with the plant to kill it and they dissipate quickly after treatment which is also beneficial.

Much like our Green Clean product for algae control, Hydrothol and Aquathol are granular and easily dispensed by topically applying it over the weed growth. Dosage rates can vary.

For safety considerations for fish, treat only one section of the pond at a time. Quartering off the pond helps to minimize rapid vegitation death, which can rob the pond of oxygen very quickly. It's also helpful to have aeration running to minimize oxygen depletion as well.

AQUATHOL granular herbicide utilizes Culigel® super absorbant 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 Eurasian Milfoil. Dosage rate is variable according to plant species. Available in granular form in 10 lb. and 25 lb. containers. 10 lb. granular treats approximately 1/3 to 1/2 acre.
