What is the best herbicide for aquatic weeds?

Diquat Herbicide is our top aquatic herbicide option for treating aquatic weeds since it is labeled to treat a wide variety of submerged, emerging, and floating weed types and is economical. Mix the specified herbicide with water in a pump sprayer according to the instructions on the product’s label before applying it to your pond.

  • Additionally, now is the moment to don the essential PPE.
  • Step 1: Mix and prepare the Diquat Before mixing and application, you must decide how much Diquat you will need by calculating the size of the water body you intend to treat.
  • Typically, acres or acre-feet are used to determine the size of bodies of water.

To do so, multiply the water body’s length, breadth, and average depth in feet by 43,560 (Length (ft) x Width (ft) x Average Depth (ft) / 43,560 = Acre-feet).

  1. Diquat should be blended with 15 gallons of water per acre at a ratio of 1 to 2 pints of Diquat per pint of water.
  2. Apply Diquat to target Pond Weeds in Step 2.

When the Diquat is well combined. Depending on the targeted weed and the depth of the water, the herbicide can be sprayed over the water along the coastline, applied selectively to newly emerging weeds, or broadcasted over the water’s surface. Some weeds are best treated using a granular herbicide such as Cutrine Plus when they are blanketed beneath the water’s surface, in deep regions of the pond, or in ponds with moving water.

  1. These thicker granules may be applied by hand with a spreader and will sink directly into the weed beds.
  2. Step 3: Treat no more than one-third of the pond at a time.
  3. As weeds die off in warmer weather, they might restrict the quantity of oxygen in the pond.
  4. To provide fish with an oxygen-rich habitat, treat your pond in tiny areas, allowing 10 to 14 days between applications.

We recommend using an indicator dye in conjunction with your herbicide so that you do not over-treat. Fourth Step: Use Vision Pond Dye Following the use of aquatic herbicides, we advise spraying Vision Pond Dye. This non-toxic dye imparts a natural blue hue to water and filters UV radiation to reduce the growth of algae and weeds.

Why does pondweed exist?

Large natural ponds are frequently plagued with pond weeds. As ponds develop and age, they frequently collect nutrients (eutrophication) and sludge, resulting in excessive plant and/or algal growth. Each year, the general growth of both desirable and undesirable plants rises and might become an issue in the future.
