I would like to find out if this would be a sound plan for weed prevention this year. First I would like to dye the lake with Aquashade or something similar early in the season. Install an aeration system, then spot treat for weeds with Navaigate or some other granular 2-4, D product. Will this help control surface algae? Will this help with my Eurasian Millfoil, coontail and duckweed? By July in previous years the Millfoil is so thick, it covers approx. 75% of the surface water. Or would I be better off waiting untill the first sign of weedgrowth and hitting it with a herbicide, then dying the pond? All input is appreciated!
