I raked a bunch of the pondweed out and treated with Reward. I was essentially 'spot treating' if that is possible. I used about 16oz of Reward and diluted to about 1 gallon then applied with a hand sprayer (this is under the recommended amount to treat the whole pond, but I did not want to treat the whole pond). The pond is .62 acres. So far I cannot tell if it is working or not.
I also treated about 1/4 of my cattail problem with Catt Plex and a surfactant. So far I cannot see the results of that. However, I did spray about 5 feet of the cattails with the remaining Reward mixture and they appear to be completely dead already.
I'm open to suggestions if anyone with experience with these products knows that I've done something incorrectly. Otherwise, I'll report back on the results.
