I guess the subject title about says it all. Is it possible to spot treat portions of my 2/3 acre pond for Sago pondweed, while maintaining aeration? I have been raking it out for over a week now, and can't tell any difference. I've got this stuff bad. All parts of the pond that are 5' or less have it on the bottom. It has reached the surface in a few spots, but mostly submerged.I posted earlier that I tried weedtrine D, but after 2 weeks there is little effect. I couldn't get the sprayed liquid down to the sago, so I'm looking into Hydrothol 191 granules, thinking they will sink down onto the pondweed. Is this a feasible idea? I know better than to kill off the entire pond at once, so how do you treat sections of it while maintaining aeration? Or do you? Am I out of luck? Thanks for any help.

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
