Systemic herbicides tend to act more slowly than contact herbicides. Systemic herbicides are absorbed and move within the plant to the site of action. Imazamox is a broad spectrum, systemic herbicide. An aquatically registered surfactant (see the label) will have to be added to the glyphosate solution for good results. They are broad spectrum, systemic herbicides. Liquid glyphosate formulations have been effective on salvinia above the water line, but ineffective on plants in the water. Water pH needs to be below 8.5 or flumioxazin will rapidly degrade and lose effectiveness.
Flumioxazin should be applied to actively growing plants and a surfactant (a substance that reduces water tension) will be needed if the herbicide is applied to foliage of floating or emergent plants. It is a broad spectrum, contact herbicide. Systemic herbicides tend to act more slowly than contact herbicides.įlumioxazin is a water dispensable granule that is to be sprayed or injected after mixing. Contact herbicides act quickly and kill all plant cells they come in contact with.įluridone is a broad spectrum, systemic herbicide. For additional information on using copper sulfate, see the SRAC #410 Calculating Treatments for Ponds and Tanks.Ĭommon trade or product names include but are not limited to:ĭiquat is a contact algaecide and herbicide. Before using copper, it is best to test the pond water’s alkalinity and adjust copper treatments to alkalinity concentrations. In very hard water, it is difficult to use copper sulfate because it binds with the calcium, precipitates out of solution, and renders the copper ineffective as an algaecide.Īll copper compounds can be toxic to fish if used above labeled rates and can be toxic in soft or acidic waters even at label rates. Smaller crystals will dissolve easier than larger crystals. Copper sulfate comes in several forms depending on how finely it is ground. Army Corps of Engineers aquatic herbicide trials.Ĭarfentrazone is a contact herbicide that is absorbed through the leaves. Contact herbicides act quickly and kill all plant cells they come in contact with.Ĭommon trade and product names include but are not limited to:Ĭopper Sulfate or “blue stone” is probably the most commonly used algal treatments because of its availability and low cost. The active ingredients that have been successful in treating salvinia include: Read the label for specific water use restrictions. Click on the name of the product to see the label.
Herbicide Control OptionsĪlways read the product label for directions and precautions, as the label is the law. Salvina weevils feed on salvina and may be effective for its management. Giant salvinia can be removed by raking or seining it from the pond’s surface, but it will re-establish from any remaining fragments.
