You'll need something like Weedtrine-D or Sonar, the first one being more affordable. Usually it's recommend to treat duckweed early. Once it's underway it's harder to treat, and takes more chemicals to do it. By the time we get into mid-summer I usually suggest just letting it run it's course and be prepared next spring at the earliest signs of it...treat at that point and you minimize the need for chemcials. One other option we've had luck with is our biospheres. These are designed to work on algae primarily but they also help with duckweed if you treat and lower nutrient loads in the water well before it show's up. We have kept it from forming in problematic ponds this way, but not after it show's up. At that point, a very targeted herbicide would probably be better. We use dye in very shallow ponds mostly to help cut down on light penetration. This can help in some cases with algae and underwater weeds but it's not done a head of lowering nutrient loads as I noted above. Instead it's used as a possible supplement to this work when it might be useful to do so. Hi Charlotte,

We have approx. one third acre with duck weed. Last summer we had filamentous algae described as matted slimy green with long roots and I applied copper sulphate and it worked great. Applied the same this spring but not effective at all on duck weed. Video suggested using acquatic hermicide, but is it too late to apply? We have a fountain in the middle of the pond to circulate, but the duck weed is increasing daily and floats with the direction of the wind. Our pond is the center of our Adult community with trees around the pond but otherwise plenty of sun exposure. Would dye help to slow down the algae growth? The Environmental Dept. is going to flush out the water lines in our homes and it will drain into the pond. This is treated water and I would like to know what effective this would have on the algae. Thank you for the info. The video was a great help in identifying our problem. We have approx. one third acre with duck weed.
