Hi Everybody,
I couldn't find any info using the search option for Duck weed.
I am in central Texas and we recently had some serious storms that blew duckweed into my pond from a pond upstream.
My main pond has great wind coverage and hopefully will help keep it pushed to the edges. But the feeder creek is holding still water and it is blooming like mad.
My big question is will this stuff still try to take over the entire pond and if so, what is the best way to control it other then getting carp which will eat every other good vegetation.
Also, if it does stay confined mainly to the feeder creek, what are the benefits vs the liabilities?

Thanks in advance for any help on this.
Kevin R.

Here is an old thread that might help.

Thanks!

Kevin, duckweed prefers calm/still waters, but can grow marginally on ponds with mild wind or fountain-induced wave-action.
The previously linked thread primarily focused on Sonar/fluridone for treating duckweed; which is probably not a viable option in the feeder creek due to the elevated likelihood of a flow-through event. Fluridone's value is only obtained if it remains isolated to the treated pond/waterway for at least 30-days - and preferably much longer.
A relatively new treatment-option is now available (it wasn't around at the time of the linked-thread). It's called CLIPPER, and it does a great job on duckweed, watermeal and several other nuisance aquatic species - and even some forms of filamentous algae. CLIPPER is functional with only a few hours of contact-time but lacks any long-term residual activity - unlike fluridone, in both respects.
CLIPPER would be my suggestion if you decide to combat duckweed in a dynamic environment such as a creek or any other BOWs that experience transitioning water, assuming the product's labeled precautions are observed.
