I can clearly see that duckweed will be a problem in my lake. I cant seem to find a source for a quality/industrial type weed sprayer. One that can reach out to say 50 feet with a broad coverage. Is there such a thing?

Dr. Bob Guillory (PS) When I finish figuring out how to decifer the instructions for posting pictures I will send you guys some cool pictures of my lake and structure. Sunil are you cold up there?
