We use an even simpler system which does require a bit more time but is easy to do. Put on a cotton glove over a rubber glove and use the cotton glove as the applicator by dipping it in the gylphosate solution and then grabbing the undesirable plant and pulling your hand up over the plant. Works great for willows. We have prevented cattails by pulling twice a month. Started with thousands of volunteers per year and now have a couple dozen per year in 4 bodies of water. I enjoy walking around the pond anyway. Just started the process over with a new wetland, but less than 100 have volunteered in the new area this year. Cattails pull easily as seedlings.
