I had a pretty bad WM problem when we first bought out farm. I actually tried Cutrine (copper based chemical) and it did nothing. After getting some help here way back when, I used Whitecap, a fluoridone based product, two years in a row and have never seen the WM again. Alas, Whitecap is no longer manufactured but there are some other products available now. Some of the experts here can probably share that info with you, but I can say confidently from my own firsthand experience, don't waste your money on Cutrine thinking it might do the trick. Save it up for the fluoridone product - you'll need the money!
