Errfoil, sorry for the mis-understanding. The Fluridone will NOT kill the Chara. I have never seen it work on Algae - Chara is a type of Algae.
I'd do a low dose treatment of CLPW in the Fall after this years seeds sprout, and plant beneficial native underwater vascular plants to re-populate the pond.
esshup, that is great news. This means I can attack the various problem plants piecemeal vs nuking the whole pond. A couple of questions; what dosage do you recommend for a 1/3 acre, 14' deep pond? Second, why wait until they produce seeds, wouldn't it be better to knock them down now before they go to seed, not to mention a summers worth of propagation?
