So after a little less than a week since the last treatment, I did another treatment at a higher mixture of the Weedtrine D - 24 oz. in 1 gallon of water with 1 oz. of Adjuvant. I concentrated the entire mixture in an area along roughly 50 - 75 feet of shoreline and as far out as the mist would go. This was about 4 days ago. We went out tonight and, while there was a nice breeze, it wasn't too heavy and I have clearly made progress on the watermeal. I have to say that we are at least 1/2 of what it used to be, and possibly 1/3 of what it used to be. With a little luck, tomorrow I'll go out in the canoe and spray again, hitting as much of it as I can effectively spray. After the initial failure at a low concentration, I was kind of discouraged, but realized that Greg and Pond Frog had been saying it would take consistent application to see any possible progress this year with the plant so far emerged. Sticking with it has proven to get us real results and, I've gotta say, it's pretty darn exciting to see it working! Back at it tomorrow if we can and hit it with another treatment.
