What makes you think there's an infestation of Phylloxera? Are you
sure you have Concord vines?

Well, it looks like my grapes are infested with grape phylloxera.
Since there's no known "cure" for this problem, I have to ask: are my
grapes even edible? Or does the whole vine have to be cut down and
burned? And if so, how long before I can re-plant (with resistant
rootstock)?

Thanks so much for your help.
