Naiads are sometimes referred to as waterweeds, they are found throughout the United States. Several common varieties cause many of the nuisance growth problems; Bushy Pondweed (Najas flexilis) Southern Naiad (Najas guadalupenis) and Brittle Naiad (Najas marina). This group grows entirely beneath the water.
Hydrothol 191 Granular is our recommendation. Mid to lower label rates will get the job done. The algaecidal ability of Hydrothol 191 is also plus. Reward and Super K are also labeled for Naiad control.
Plants must be present to treat. Water temperatures should exceed sixty degrees Fahrenheit.
One to two treatments per season are usually plenty.
Generally within twelve to sixteen day things will be cleared up.
