Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants NEED HELP IN OREGON

I'm no expert but as I mentioned before I used a Reward/Cutrine mix in my pond. I mixed the Reward/Cutrine with water as per the instructions on the labels and using a garden sprayer (we have one sprayer that we use exclusively for pond use, a blue one so the color reminds me it's only for pond use. A separate sprayer for the pond might be overkill but I didn't want any residual chemical from Roundup being injected into the pond). The Reward/Cutrine mix is heavier than water so it sinks. I put the "wand" of the sprayer beneath the surface of the pond and injected the mix right where I wanted it. The mix was a deep purple color so it was very easy to see where it was in the water. I think as long as you don't have too much water movement that you can keep the mix in a general location as opposed to having it move around the pond. I have a spring in my pond so when I sprayed it near the spring we could see the mix moving around. Still we were able to spot treat certain areas that needed some additional attention. I was very pleased with how the Reward/Cutrine mix obliterated the Elodea.
