    What is the most cost effective way to get rid of Curly-Leaf Pondweed? I have about 3 acres of it. Thx

    Is it in a pond? I was the chairman of the Sanders County Aquatic Plants Task Force in Sanders County, Montana and we had a long term project combating Curlyleaf and Eurasian watermilfoil. We did a lot of scientific testing with Mississippi State University and contracted an aquatic invasive plants specialist with the Corp of Engineers. If you just want to reduce the infestation seasonally, an aquatic rake is economical but time consuming, and obviously a short term fix. There are a number of aquatic herbicides that are effective, and timing the application can reduce non-target damage to desirable species somewhat. I’d be happy to discuss it more with you if you’re interested in going that route.

    It appears I am surrounded by experts.
    Diquat will burn it quick but you’ll have to spray every 2 weeks to eliminate completely.

    I just re-read my own post and I honestly didn’t mean for it to sound like I’m an expert. What I was trying to get at is that I could help you access a lot of information. I’m sorry that came across like I was patting myself on the back, that was not my intent at all.
    Cheers!

    Thanks for the responses. It is a large slough on the Mississippi River and no offense taking. Sounds like you know a lot more than I do which is appreciated. This is the first time I seen this weed. We flood every year due to the river flooding and seems to bring in a new collection of seeds or new challenges. We use the slough for duck hunting so at some point in the summer I like to clear the slough as much as I can to make it easier for decoys and access for dogs. Has anyone used copper sulphate? I can try Diquat but applying every two weeks may be tough.
