Bill I didn't do a dormant spray this year. I really didn't have much disease last year, just a few spots. I probably should go with a dormant oil, but haven't used it to date. I mention disease because it is ever present in the environment. Without diligent preventative sprays it is likely that we get disease manifesting in one form or another. The rains compound the problem because each inch of rain you get, the spray residue is halved. This reduces the effectiveness of the spray in disease prevention.
Tuesday we had visitors at the Willsboro Farm. A bunch of the personel from the Hort Department were visiting area orchards and farms. We were on their stops. Many interesting folks were there and they all were looking for any pests they could find- be it insect or disease. They all had their little magnifying glasses and using them. I had the pleasure of meeting Dr. Julie Carroll from Cornell. She is a plant pathology specialist. We talked a bit about spraying with all the rain pressure we have had. We all hid out in the greenhouse for a while- during a downpour, then went over to the vineyard. After they all left at about 6:30 PM, I went back to work and sprayed the grapes. It remained fairly dry overnight to give the spray a chance to dry on.
How are your vines doing? Did the goo ever go away?
