Powdery Mildew

Posted by Kit.578 (My Page) on

I am wondering what would the best powdery mildew fungicide for wine and table grapes. I want something organic and have found that sulfur, Serenade, Sonata and Organic JMS Stylet oil are all acceptable. I am thinking sulfur would be the cheapest and most affective. The only problem is, there are many types. Some websites recommend the powdered form, and others say liquid. Any ideas?

I prefer the powder form. Usually it's a 5lb per acre rate with atleast 30 gallons per acre. If it's for garden use, you can mix about 2-3 ounces per gallon of water. It's best to spray mid morning or late evening, when temps are below 90. Sulfur has no residual or systemic effect, so spray after rains and cool overcast days.
