Hello everybody I'm a long time reader, first time poster , and I'm in need of some advice. I have a small GSM vineyard ( 200 vines, 4 years old) in Northern CA. I'm having an issue with what looks like powdery mildew on the canes( dark splotches) and grapes covered in grayish powder . I have never sprayed because I thought it was unnecessary due to the excessive heat we get in our area ( routinely between 95 and 105 deg in the summer and harvest . What would be your advice at this point in the season ? At this point there is plenty of good fruit to make wine . I plan to harvest what's good in about a month . Thanks in advance for any advice
