Finally, here's the 2011 version of fungicide spray guide for VA wine grape (bearing vines) . I hope it will help you come up with your spray schedule for 2011. Please spend a few hours before the season to think about your spray program. It will help to: 1) have a plan of what and when to spray; 2) check inventory of your chemicals; and 3) come up with a rough budget. I understand that you will need to change the plan based on weather conditions etc, but having a plan prior to the season will help you tremendously during the season.
