Hello all, I have been reading this forum for three years and decided to join. It is amazing the amount of information that is available here. I have a 1/3 acre pond that is about ten foot deep in the center, located in Iowa. I recently purchased some Clipper herbicide to try and control some duck weed, watermeal, and coontail that is in my pond. It sounds like I need to add a surfactant to the mix and was wondering if someone could point me in the right direction as to what type/brand to use? I plan on applying with a back pack sprayer early in the morning. I only have a little bit around the edges of the pond now and want to try and get it under control before it gets out of hand. I have tested PH only a couple of times late in the afternoon and it was around 8, so hopefully it will be lower in the early morning. Any advice would be appreciated.
