The Northern Grapes Project Webinar Series

Dear Northern Grapes Project Webinar participants:

“Northern Grapes Survey Results: How the industry changed from 2011 to 2015”

Brigid Tuck Tim Martinson
University of Minnesota Cornell University

Tuesday, December 13th, 2016

12:00 Noon Eastern (11:00 am Central)

7:00 pm Eastern (6:00 pm Central)

Two industry surveys, conducted by the Northern Grapes Project in 2012 and 2016, tracked changes in acreage, wine production, and economic impact of cold-tolerant grapes across the Midwest and Northeast. Increases in acreage, production, and sales were recorded. Overall economic impact from Cold climate cultivars increased from $401 million in 2011 to $539 million in 2015. The number of industry-associated jobs increased from 12,600 to 18,700 in 2015. Viticultural and winemaking practices changed over the five-year project, reflecting impacts of Northern Grapes Project research and outreach.

Strep Resistance, fire blight management Tools

category [tree fruit, IPM]

Good morning,

Dr. Quan Zeng, CAES, has been working on Fireblight and strep resistance, and has presented information on-line for you. Many of you submitted samples for this work which helped a great deal. The following is from Quan.

Below you can find a link to the webinar presentation I produced with Plant Management Network regarding fire blight and streptomycin resistance. I summarized the survey we performed, that as of 2016, the New England region is free of streptomycin resistance. I also provided an overview of how the resistance happens, current updates, and some future management tools as alternatives to streptomycin.

Northern Grapes Update

To all past registrants for the Northern Grapes Webinar series:

Our thanks to the industry groups that have contributed ‘gap’ funding to support continued outreach for the Northern Grapes Project:

Iowa Wine Growers Association
Illinois Grape Growers and Vintners Association
North Dakota Grape and Wine Association
Eastern Winery Exhibition
Colorado Wine Industry Development Board
Michigan Wine Industry Council
Connecticut Vineyard and Winery Association

Collectively these groups have contributed or pledged $9000 toward the goal of $20,000 in support.

We are still looking for other state support to cover this project- TB

Plans are underway for the next season of the Northern Grapes Webinars.

1. First Webinar: We will kick off the season on December 13, with a look at how the acreage, production, wine production, employment, and economic impact of the Northern Grapes industry has changed since our first survey in 2011.

2. Suggest a topic: As we line up programs, we would like to know what topics or questions you would like us to cover.

Please post your comments on our Northern Grapes Project Facebook page:

https://www.facebook.com/NorthernGrapesProject/

3. Crave Conference: Each year, Cornell Viticulture and Enology researchers, graduate students, and extension specialists get together to present 15 minute talks to each other on research and extension topics and projects from the previous year. This is our way of finding out what our colleagues at Cornell are up to. These talks cover a variety of topics, and represent preliminary results that are ‘hot off the presses’. Some are quite technical, though they should be understandable to those involved in grape and wine production. I invite you to connect via WebEx to our web broadcast for as much or as little time as you want. Because much of the information is preliminary and unpublished, we will not be recording it. Hope some of you can tune in to our webcast for topics that interest you.

Tracking grape ripening

By Terence Bradshaw

As harvest approaches, it is critical to track ripening in the vineyard to best achieve the juice chemistry values to optimize wine quality. Sampling should be methodical and regular (at least weekly, or more often as harvest approaches). Generally a 100 berry sample is sufficient to ascertain general ripeness. Berries should be randomly selected, but should come from a diverse distribution in the vineyard: from all parts (top, shoulder, bottom) of the cluster, and from clusters well-distributed through the canopy. Fruit can be collected into a plastic bag, crushed lightly, then a corner of the bag cut off to squeeze juice into a sampling jar. Juice should then be assessed for pH, sugars, and titratable acidity (TA). Remember that for most popular cold climate grapes, TA is a primary determinant for ripeness; for reds (Frontenac, Marquette), a target TA of 1.5% or lower is preferred; for whites, 1.2% should be considered the upper end, although La Crescent may frequently have higher values. Ideally, all grapes for winemaking should have TA below 1%, but that is not always possible for the cultivars that we grow. Work with any wineries you plan to sell grapes to to determine their preferred juice chemistry levels before harvest.

Juice chemistry tracking for cultivars in the UVM vineyard may be found at: http://www.uvm.edu/~fruit/grapes/uvmvineyard/2016UVMfieldtesting.pdf

A primer video on evaluating grape ripeness may be found at: http://www.extension.umn.edu/food/small-farms/crops/knowing-when-to-harvest-your-grapes/

Dr. Imed Dami at Ohio State has a good fact sheet on evaluating grape ripeness at: http://ohioline.osu.edu/factsheet/HYG-1436

Sugar level and pH are easily evaluated with simple tools (a refractometer and pH meter, respectively) available from most winemaking supply outlets. TA test kits are typically available from the same vendors. A procedure for measure TA through titration is available at: http://www.extension.iastate.edu/wine/titratable-acidity

Time for Retain application in Vermont orchards

By Terence Bradshaw

Apple harvest is just around the corner with reports of early varieties like Paulared and William’s Pride coming in as ready to pick. The use of plant growth regulators to help with harvest management and improve fruit quality is an important tool in many orchards. ReTain plant growth regulator is used to slow ethylene synthesis in ripening fruit to delay maturity and reduce preharvest drop. Given the dry and hot conditions experienced this summer, drop potential is high, and growers should plan on treating their orchards more often than not. One or two applications may be made at the rate of one pouch (11.7 oz) per acre each. Application 21 to 28 days prior to normal harvest will delay ripening 7-10 days and improve fruit storability. ReTain is especially recommended on McIntosh, and reduced rates (1/2 pouch each application) suggested for Macoun and Honeycrisp. ReTain also improves fruit quality on Cortland and Gala.

Dr. Duane Greene from UMASS recently outlined the following guidelines for ReTain use in 2016:

“Apply ReTain in a sufficient amount of water to ensure that flowers, fruits, and foliage receive thorough spray coverage using calibrated spray equipment. Adjust water volumes based on plant size and spacing. However, excessive spray application volumes resulting in spray runoff will reduce product efficacy.

Avoid applications during the heat of the day. For best results, apply ReTain under slow drying conditions, e.g. early in the morning or at night, in order to maximize adequate absorption.

Do not apply ReTain if rain is expected within 8 hours of application.

Do not apply ReTain to plants of fruit under considerable stress (i.e., heat, water, disease, insect).

Maintain application solution between pH 6-8.

For optimal response, use ReTain with a 100% organosilicone surfactant. Use a final surfactant concentration of 0.05 to 0.1% ( i.e. 6-12 oz surfactant per 100 gallons spray water) in the spray tank. To prevent possible spotting, use the 0.05% concentration when high temperature (in excess of 86°F) weather conditions prevail or are anticipated. Do not use a surfactant concentration greater than 0.1%. To reduce foaming, add the adjuvant last and minimize agitation.

ReTain may be applied in a single application of 1 to 2 packets per acre (or less), or in two applications of 1 packet per acre (or less) each. See the Supplemental Label for additional information: http://bit.ly/2bar9gZ

ReTain has a 7 day pre-harvest interval (PHI) for Apple and Pear.”
