Thank you for this report. Using two parts of milk and three parts of water and spray the leaves, after removing heavily affected leaves, seems very effective. Might work just as well as sulfur. I like organic solutions. It seems to work also against aphids. You kill two birds with one stone. I remember buying grapes in Israel with a dusting of sulpher. I had to rinse off the sulpher before eating, but didn't get all sulpher removed.
Nice report. I'm tending to a small Pinot Noir vineyard that has been abandoned for a few years so I don't have any history of past powdery mildew infections. I did my first sulfur (3Tsp/GAL) spray last week and covered all the leaves, canes and trunk. I mixed in some seaweed extract which is supposed to help with adhesion and iron/zinc mix which is supposed to help with shatter. Have you heard of this? I'm going to spray on a 14 day schedule. Do you have any suggestions on when to reduce the sulfur amount per gallon? Also, how often should I be spraying the bark areas like the trunk? Thanks!
I only spray the back early in the season. If you have no or little powdery mildew you may not need the high dosage and reduce spraying. It really depends on your conditions. Once you have powdery mildew you should stay vigilant!

Thank you Francis, but I would rather use sulfur. I am lactose intolerant! Ha ha!
