Here's the situation. I'm in south central illinois, the pond is 5.5 acres and the pond has about 40% (2-2.2 acres) coontail. The water is very clear and the coontail is growing in ranges from 4-14ft with the average growth in 8-10ft of water. I've narrowed my chemical choice down to Aquathol K, Super Aquathol K pellets and Sonar (Q or PR). There are other plants present such as Cattails and Creeping Water Primrose that I want to remain in the pond. My questions involve application rates to specific areas while avoiding dilution, application techniques and which combination of chemicals and techniques will be most cost effective. My tools for application are either a 25 gal ATV sprayer or a 40lb manual lawn spreader. I would like to treat the Coontail before it mats on the surface but if there is a significant cost advantage to treating it on the surface then I'll most likely wait.
