I treated some ball moss over two weeks ago with copper hydroxide (Kocide 3000) and have seen no results. I mixed the tank per label instructions and I know my sprayer is calibrated correctly. The only thing I can think of that would cause it not to work was the temperature. The forecast for that day was to be in the sixties, but I know when I was spraying it was still in the forties. Is it possible it was just too cold? I've read the label several times and can't find anything pertaining to what range of temps are most effective (that doesn't mean I couldn't have missed it). If any of you could help, it would be greatly appreciated, I have lots of moss to treat.
