I dilute CUTRINE PLUS 9 to one with a surfactant FOR FA WHEN THERE IS NO DUCKWEEK. Works great, but the floating FA turns white before sinking, not brown. If you happen to catch a rain a couple of days later then everything on the surface will be gone. When I need to spray for FA and duckweed I use the same 9 to 1 on Diquat and spray them both together. Surfactant is a key ingredient, I use cidekick, and if not available just plain old pink dish washing detergent. I REVISED THIS TO MAKE IT MORE CLEAR (AT LEAST MORE CLEAR TO ME). THE ALL CAPS WORDS ARE THE REVISION
