Weeds/Algae Control

For treating weeds and various forms of algae, we recommend a variety of effective products. Find your weed below and click on the image for the recommended treatment.

Common nuisance plants like duckweed, Eurasian watermilfoil and hydrilla can be selectively controlled while more desirable native plant species are left to thrive. Selective, long-term control of undesirable aquatic vegetation can be achieved for a year or longer with one application.


Algae
Algae are very primitive plants. Some algae are microscopic (planktonic algae), others are thin and stringy or hair-like (filamentous algae), while still others are large and resemble higher plants but without true roots (muskgrass/chara).


Filamentous Algae
Muskgrass, Chara
Planktonic Algae

Emersed Plants
Emersed plants are rooted plants often along the shoreline that stand above the surface of the water (cattails). The stems of emergent plants are somewhat stiff or firm.


Cattails

Floating plants
Floating plants are not attached to the bottom. Floating plants come in sizes from very small, such as duckweed, to over a foot in diameter, like water hyacinth. Most have roots that hang in the water from the floating green portions.


Duckweed
Watermeal
Azolla

Submersed Plants
Submersed plants are rooted plants with most of their vegetative mass below the water surface, although some portions may stick above the water. One discerning characteristic of submersed plants is their flaccid or soft stems, which is why they do not usually rise above the water's surface.

Sonar Q Shaker
Our Price: $182.25
5 lb of aquatic herbicide pellets in a shaker container with handle

Sonar is the most effective and cost-efficient treatment you can buy for the selective, long-term control of undesirable weeds. Sonar Q is the fastest-releasing Sonar pellet in a quick, easy-to-apply formulation that selectively manages undesirable aquatic vegetation for a year or longer. Sonar Q has the efficient concentration level of a liquid, but provides for more accurate placement. The pellets will land where they are thrown, eliminating overspray onto sensitive shoreline vegetation like lawns.

This pellet formulation is recommended for use in water bodies with sandy or rocky bottoms.

Sonar Q accelerates the release of fluridone concentrations into the water column. Sonar Q provides a longer-lasting residual than liquid Sonar A.S., and still delivers an effective dose to targeted plants within the first day. The rapid pellet expansion allows the product to release fluriudone quicker while remaining buoyant on sandy or firm bottoms, avoiding complete organic tie-up. As Sonar Q is immediately carried to the bottom of the waterbody, Sonar's active ingredient is less likely to be impacted by initial light degradation, preserving valuable fluridone parts per billion (ppb's) for targeted plant control.
