Need help with grapes...

NAUgrad2005

I planted 3 different varieties of grapes when I moved into my home 6 years ago: Thompson's Seedless green grapes, Concord grapes and a red grape. The plants did well and bore fruit each year, but I've lost my crops the past 2 years due to powdery mildew. The vines grow in a planter area in the corner of my backyard but span roughly 15 feet wide along the fence. During the season, I was diligent with keeping my vines open and airy. This year, I think I'll try to treat them. I'm at a loss of what to do this spring though,,,should I cut off any areas that still look diseased? The vines are watered by my sprinkler system daily throughout the spring and summer, although the sprinklers only run for about 10 minutes in the backyard. Please help...I'm a grape novice!
