Noticed powdery mildew on rachises of Chambourcin in the MVEC vineyard. Cayuga White and Seyval Blanc are going through veraison. Noticed a few bird pecks on the Seyval Blanc in the Research Vineyard and the Cayuga White in the Foundation Vineyard. Pesticide was applied last week for Japanese beetle and I did not  see any new evidence of damage.
