I have a half acre pond and have sprayed White Cap per the directions to kill my plush bank to bank carpet of duck weed. It has been almost 4 weeks and it is taking its sweet time killing it. Will I have to spray again any time soon.
Thanks Jeff

I dont think you are supposed to spray white cap. When I use it I mix it with water in a five gal. bucket and then just poured it into the pond. Its not a contact spray. How many oz. did you use in your pond? When I did one of my 1/2 acre ponds to kill watermeal I used 32 oz and within 60 days there wasn't any weeds in the pond anywhere. It says that it could take up to 90 days to work though. Was there still water flowing out of the spillway when you used it? Have you been seeing any resultd from where you sprayed?
