VASCM: FW: Important information on Red Blotch Disease of grapevines

[Ed Muns]

Wednesday seminar, "Current Issues in Vineyard Health", was very
informative.  One topic covered in depth is the so-called "Red Blotch"
disease, a newly discovered virus that has shown up in Napa, Canada and
South Africa.  It is probably in other locations too, but just not yet
identified.  Attached is a leaflet just released on the disease.  It is
still being evaluated and characterized.

Importance: High



If you weren't able to attend the UCD Extension seminar yesterday entitled
"Current Issues in Vineyard Health", you missed a very important discussion
of the newly-discovered viral disease hitting California's vineyards: for
lack of a better name, Red Blotch disease. 

Its symptoms distinguish it from Leafroll Virus, as does its PCR
fingerprint.  For the most complete information available on the disease,
please see the attached brochure, developed by Dr Jim Wolpert, our
Viticulture Extension Specialist, and Dr Mysore Sudarshana, a researcher in
Plant Pathology at UC Davis.

If you just weren't able to get your grapes up to target Brix this year, or
if your field samples fell well short of your expectations, you might
consider Red Blotch as the reason. It always helps to understand your
roadblocks, and maybe pick, or thin,  accordingly.

 

Keeping you informed.........
