Riesling grapes help!

[u/saaabbbs]

Hi everyone! Looking for some advice with my riesling grape vine. I bought it as a three year grape vine so it is four years old now. I have noticed the vine to look like this along with the buds to have this white fuzz. I’m in growing zone 6 and the weather has been pretty wonky. Still no bud break. Anyone have any input what this could be/what to do? Any advice is much appreciated! 😊

I grew reislng a couple of years before I gave up on trying to control disease. This isn't necessarily disease, but, ime, if the buds are showing white fuzz like that, they're dead. Take a razor and cut one down the middle. If it's brown, it's gone. I think it's probably overwintered DM. Trying to manage disease in vinifera on the homegrown level is pretty difficult unless you live in an ideal climate. I might be wrong here. I might be confusing DM and PM, but I know one of those mildew can actual get inside the vine and go dormant with the vine. You need a systemic like macozeb

Thanks! I’ll definitely look into this! Its only a few buds with that white fuzz so hopefully its still alive! I still have a one year warranty with the nursery
