Anthracnose is a disease that I have seen mostly in new plantings of Cold-hardy cultivars in New York. I happen to think that the conditions for it to spread and take hold (warm, humid springs) are more common farther south than here in NY, but it has appeared in several vineyards here in NY.
The fact is that in vineyards with a history of Anthracnose, dormant lime-sulfur sprays are one of the principal ways of controlling it.
So I want to share with you Mike White’s article on Anthracnose. Here is the link: Wine Grower News #356 3-30-17-2e3o64u.
Lime-Sulfur is a very corrosive material (for painted surfaces), but very effective on dormant vines with existing Anthracnose. Note that if you do not have a history of Anthracnose, you probably don’t need to do this.
Ohio State has a nice Anthracnose Factsheet. We don’t have one in our Cornell IPM factsheets, because it has been very rare in commercial vineyards here in NY.

We collected our first samples from Frontenac, Frontenac Gris, La Crescent, Marquette, and St Croix on 8/22/2016. Starting next week we will begin posting these in our publication Veraison to Harvest.
Samples were collected from the Thousand Islands (Clayton), Champlain (Willsboro trial), and the Finger Lakes (various locations). Each week when we post Veraison to Harvest, we’ll post a table of contents and link here.
Here’s the results:
I’d like to call your attention to a series of instructional videos on vineyard establishment, pruning and tying, done by Tom Zabadal at Michigan State University. This series of 38 videos (!) covers the ‘nuts and bolts’ of establishing different training systems, tying grapevines, and trellis construction, all presented in a careful ‘step-by-step’ format. These are highly specific and practical (for example there are 4 separate videos on tying, including situations where tying is needed, materials used for tying, techniques used for tying, and specific knots used for tying. Dr. Zabadal is a research/extension professor based at the Southwest Michigan Experiment Station in Benton Harbor, Michigan.
I highly recommend these as a resource for learning about basic viticultural techniques!
A few examples:
2016 Northern Grapes Symposium
The 2016 Northern Grapes Symposium was hosted by the Michigan Grape and Wine Industry Conference on February 24th in Kalamazoo, Michigan. Nine Northern Grapes Project team members lead six sessions, encompassing all four of the projects’ objectives. Some of the talks focused on results of specific research projects, such as training systems studies, deacidification strategies for cold hardy wines, and marketing, branding, and tasting room studies. Others, however, were more general in nature, and covered topics such as the past 15 years of viticulture in Iowa and the viticultural and enological characteristics of Marquette, Frontenac, Brianna, and La Crescent, including tasting two examples of each wine.
Below are links to all of the presentations given at the 2016 Northern Grapes Symposium:
Fifteen years of trials, tribulations, and successes in Iowa viticulture. Mike White, Iowa State University.
Making quality wines from high acid grapes: Yeast selection and deacidification. Anna Katharine Mansfield and Claire Burtch, Cornell University
Brianna and La Crescent: Viticulture, enology, and tasting. Jim Luby, University of Minnesota and Murli Dharmadhikari, Iowa State University
Marquette and Frontenac: Viticulture, fruit ripening, enology, and tasting. Jim Luby, University of Minnesota; Murli Dharmadhikari, Iowa State University; and Anne Fennell, South Dakota State University
Managing Frontenac and Marquette for profitability and quality: Training systems, recovering from winter and spring frost injury. Tim Martinson, Cornell University and Paolo Sabbatini, Michigan State University
Marketing, branding, tasting room studies with cold hardy wines. Bill Gartner, University of Minnesota and Dan McCole, Michigan State University
We would like to thank the following wineries for donating or providing wines at a reduced cost for our symposium: Coyote Moon Vineyards, Clayton, New York; Fireside Winery, Marengo, Iowa; Flying Otter Vineyard and Winery, Adrian, Michigan; Northern Sun Winery, Bark River, Michigan; Parley Lake Winery, Waconia, Minnesota; Shelburne Vineyard, Shelburne, Vermont; Staller Estate Winery, Delavan, Wisconsin; Tucker’s Walk Vineyard, Garretson, South Dakota.
“Developing Cold-Hardy Grapes: The Trials and Tribulations of Breeding Grapes for the Northern Continental U.S.”
Harlene Hatterman-Valenti Matthew Clark
Tuesday, March 8th, 2016
12:00 Noon Eastern (11:00 am Central)
7:00 pm Eastern (6:00 pm Central)
Join Harlene Hatterman-Valenti of North Dakota State University and Matthew Clark of the University of Minnesota as they talk about their respective grape breeding programs. During this webinar, they will give a brief history of their grape breeding both programs, and will discuss how crossing and selection decisions are made, including using molecular tools for cultivar development.
