Duckweed is a free-floating plant that can easily cover an entire pond. It appears as a single leaf or a cluster of three leaves with very fine roots that hang down from the underside. Imagine miniature one, two or three leaf clover about the size of a pencil eraser; sometimes smaller sometimes larger.
Herbicide treatments work when it comes to controlling duckweed. Duckweed is a common pond issue. Use the correct product, apply it per label directions and you will be happy with the results. We are always here to help guide you before and encourage you to contact us following your treatment to ensure every future application meets your goal. See next Q & A - Which Herbicide When? for product recommendations.
Other Control Methods It is our opinion that some techniques work as a complement to aquatic herbicide treatments, such as aeration/fountain systems or bacterial treatments, but will not replace the need for a herbicide maintenance program. We know of no skimming technique or equipment that will successfully control Duckweed.
Duckweed must be present to treat. Earlier in the day is best. Avoid water temperatures less than 50º. As long as the plant appears viable/active results should be excellent.
Clipper is a granulated formula that easily mixes with water. It comes with a measuring cup - mix with water and apply to surface area allowing for even distribution. Effective concentration levels drop fast with Clipper so go the extra mile to get as good of coverage as possible. Always see the label for exact directions. Apply with a handheld or backpack sprayer.
A Great Tip: Back pack sprayers cost more but they hold more product, get the job done faster, spray farther and are much easier to use than carrying a hand held sprayer. Once you use a backpack sprayer there is no going back – You can use it for all your yard weed control and fertilizer applications too. Always triple rinse spray tanks after each use! If you are an occasional user the hand held sprayer can get the job done too.
