Current Situation 6/15/2012

Greetings, all!  I (Chrislyn Particka) am writing the blog post this week as Tim is in the Midwest, touring grape nurseries. 

Scouting and Disease Management 

This week, Zac noticed some powdery mildew (2% of leaves infected in all varieties) at one vineyard and some anthracnose (40% of Frontenac leaves affected) at another.  This is an excellent reminder that we are still in the most critical period for disease management!  Bloom finished in just about all areas this week, but the following four weeks is still a critical infection window for powdery mildew, downy mildew, black rot, phomopsis, and anthracnose on grape clusters.  The March Northern Grapes Project Webinar “Grape Disease Management Basics (and All About Anthracnose)” by Patty McManus and Wayne Wilcox has a lot of timely information, and can be viewed by clicking here.  Tim’s blog post from last Friday also had some good links to disease information and I encourage you all to check them out if you haven’t already.

Growing Degree Days

Current GGD at Watertown:  615 as of June 14, 2012. 

Last year, there were 479 by the same date. 

It was June 23, 2011 before 615 GDD were accumulated, so we’re still about 9 days ahead of last year. 

Upcoming Field Day

A Cold-Climate Grape Field Day is scheduled for Monday, June 25th at Coyote Moon Vineyards in Clayton, NY.  We’ll have a vineyard tour to view the studies we initiated this spring for the Northern Grapes Project and talk about the resources the project has generated thus far.  Also, Mike Hunter with the Jefferson County CCE will talk about the worker protection standard, Zac will give a scouting update, and Jim Trezise from the New York Wine and Grape Foundation will talk about the importance of wine and grapes in the north country.  A flyer, with further details including registration information, can be found here.
