I had a severe water shield problem this year on an >8 acre pond and have been using a product called weedtrine in small doses over the last 2-3 monthes. It has signifigantly reduced the coverage of this plant.
Does this type of plant deteriorate over summer monthes or am I actually killing it? The leaves turn to brown within a 12 hour period with each use. So, that tells me I'm killing it but am I wrong to assume this? Am I just killing the leaf?
