Re: Grape Disease Identification Request - Grape Leaf Disease.jpg (0/1)

How much does it cost for a tissue analysis? If Alabama does not offer
the service, I wonder if I could send a sample to other states that
do? That's to bad to hear about your fruiting bud loss. I assume that
was from the late freeze? We're lucky this was our first year and we
obviously aren't worried about fruit. This could have been a total
loss otherwise. I'm hearing local peaches were devastated. That's a
shame. We have some of the best peaches in the US!

Thanks for the advice Paul. I'll check into the Ag service for help.

of torrential rainfall on still wet (from spray

May 11-23 - Drought. Absolutely zero rainfall in

to drink.

Looking for positive identification of disease
of what to do moving forward. Symptoms are
apparent on many leaves making it impractical
and risky to defoliate since these are
first-year vines with little vegetation.

What to do? Are we in trouble?

HELP!!!

Thanks,

Charles, I do not know about Alabama but some
states have people in their Ag Extension than can
help. If you were in Pennsylvania or nearby, you
could send in a tissue sample and have it
analyzed.

Don't be overly convinced that you have a disease.
It is quite possible that you have a nutrient
deficiency or excess - such as Potassium. I am
no expert but you should consider this
possibility. The dry spell you are having could
have made this problem worse. In the meantime,
keep drinking. Ain't this wine growing fun ;-)

I lost 90% + of my fruiting buds this year in
Central Maryland. Surrounding vineyards fared
better but I have a micro climate in my backyard
vineyard. I am near a ravine and the cold air
apparently goes down the hill and settles before
it proceeds it's downward path.

Ya, I am drinking more this year also.
Fortunately, I have an excess of wine in my
cellar from previous years and Mead making has
gone into high gear this year. I am also boning
up on cane pruning because I will be doing a lot
of it next spring to either go that route or
build new cordons for cordon-spur.
