I have a 2 acre vineyard on Setterbo Rd. I have poweredy mildew. The first signs showed up arounf the 4th of July. I sprayed Stylete Oil (1%) on the 10th and again on the 23rd. (2%). We plan another treatment using coper sulphate and sulfer this weekend and the stylete (2%) on 10 days. Do you have any suggestions on a better treatment strategy? I fear I have lost most my crop this year but I am not sure. i am a weekend farmer but I do have someone working on my vineyard the resides in the area (Warren Schaub). Hope you can help.
