[Growwine] vidal

[Steve Melchiskey]

Laura,
It was very limited to a 10 vine stretch of one row and the  
prevailing winds carried it over to the same 10 vine stretch of the  
next two rows. I can trace the infection to missing a spray when my  
equipment glitched in that row, but I can't be sure.

  I just kept cutting it out and cutting it out throughout the season  
at any sign of it and it kept  it under control,  and this year I'm  
spraying way more frequently with Soap Shield, Sonata and Serenade. I  
also did a dormant spray, which has helped. I think copper/soap is  
probably the right answer, but I don't want to rely on something else  
and be wrong.
best,
steve
