Saturday's disease risk event

Oops, this one slipped out from my mind over the weekend!  I calculated the value, satisfied, and forgot to upload!

In anyway, from Friday night, we had a wetness event of 15 hours with average of 65F.  It was an infection event for downy mildew, Phomopsis, black rot, and Botrytis.

Most of us are probably close to the end of the critical period for cluster protection, and probably planning for (or even finished) the third cover after bloom, which is typically the last critical period spray. Hopefully, you are having a clean vineyard up until this point so that you can relax a bit after next spray!
