Sonar, the leader in aquatic herbicides, now offers an easy and effective formula that requires no mixing, no special equipment, or even a boat. Now, thanks to Sonar Ready-To-Use (RTU), anyone can take control of aquatic weed management. Simply apply this improved formula from the shoreline and, within weeks, the targeted plants will begin to turn white and wilt away. Recommended for man-made or natural ponds that have limited or no outflow.
No other treatment is more effective against duckweed. Often spread from one body of water to the next by waterfowl and other wildlife, duckweed is one of the most common and most persistent aquatic weeds. And while it may look like algae, it is actually a plant. And because it reproduces so rapidly, your pond can become completely covered in duckweed in just a matter of weeks. Before your pond and its fish population and its recreational uses begin to suffer, treat with Sonar RTU. Its active ingredient, fluridone, targets and controls weeds right down to their roots. And any of the product that is not absorbed by plants is quickly broken down simply by sunlight. Sonar guarantees results. See manufacturer’s label for details.
For best and long-lasting results, apply to your pond at the first sign of weed growth. Application rates may vary, but for a ¼ acre pond with an average depth of 4 feet, one quart of Sonar RTU should be used for the initial treatment. In 21 days, a follow-up application of ½ quart should be applied. Then one more application of ½ quart should be used 42 days after the initial treatment. Sonar RTU-treated water should not be used for irrigating crops, ornamental plants, or established turf for at least 30 days after the final treatment. Similarly, do not use these treated waters for watering seedling grasses, new crops, or other plantings for 60 days following the last application.

Aquatic weeds, whether floating, submerged, or emergent, can quickly become overgrown in any pond, lake, reservoir, or even drainage ditch. At the first signs of weed growth, turn to fast-acting Reward. The broadest-spectrum formula available, Reward is particularly effective against duckweed, pondweeds, naiads, water milfoil, and coontail. Upon application, this contact herbicide is absorbed into plants in a mater of minutes. Not only does this immediately start the treatment process, but it also ensures that the concentrate quickly dissipates from the water, thus posing minimal risk to the surrounding environment and wildlife. When using Reward, you can be confident that you will not be contaminating groundwater or increasing toxicity levels in your pond’s fish species.
Because it is a contact herbicide, it is most effective when applied to active growth. When treating duckweed, using in conjunction with a non-ionic surfactant is recommended. Reward’s potent concentrated formula means low use rates. Application rates vary from 1 to 2 gallons per surface acre depending upon water depth and type of weed being treated.
Best of all, there are minimal water restrictions following treatment. Following the application of Reward, user should wait 1 day for livestock consumption, 1-3 days for human consumption, 5 days for irrigating food crops, and 1-3 days for other irrigation purposes. See manufacturer’s label for specifics.

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.Learn More
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.
