I. Current situation

This issue of Viticulture Notes completes 20 years of continuous publication (120 issues). I hope that all of our readers enjoy a bright New Year and will stay tuned for Volume 21! TKW

A. Virginia Tech's 2006 PEST MANAGEMENT GUIDES are available on-line in PDF format and are divided into three volumes: Field Crops (456-016), Home Grounds and Animals (456-018), and Horticultural and Forest Crops (456-017), which includes the grapes component. Each of the volumes is divided into sections. The web site is: http://www.ext.vt.edu/pubs/pmg/#hort .

B. Virginia Vineyards Association Grower of the Year Award: The Virginia Vineyards Association (VVA) is pleased to announce the founding of a Grower of the Year Award to be announced during the Annual Technical Meeting to be held in Charlottesville in February 2006 (see upcoming events).

The VVA is therefore seeking nominations from its members for this prestigious award. At minimum candidates should be:

  1. Nominated by an active member of the VVA.
  2. Have managed or operated a vineyard in Virginia for at least seven years.
  3. Have a minimum of five acres of vineyard.
  4. Have contributed to the Virginia viticulture industry.
  5. Be an active member of the VVA.

Nominations should be sent to the VVA at P.O. Box 91, Clifford VA 24521 by Jan 15, 2006 for VVA Board consideration.

C. How cold-hardy are the vines?

Each year my assistant Kay Miller conducts routine measures of dormant bud cold hardiness under lab conditions. The ultimate purpose of this exercise is to evaluate how our treatment of the vines impacts their ability to tolerate cold temperatures, or how cultivars and clones differ in cold hardiness. Remember, despite our slow warming of the earth's climate, low temperature injury is still the prime constraint to vine survival in Virginia. The lab technique essentially simulates what vines might experience in the field during a killing freeze. We freeze a sample of buds and determine the temperature at which they are killed. This temperature is termed the MLTE temperature on the right-hand axis of Figure 1 below, where the temperatures are shown in degrees Fahrenheit. The figure depicts the MLTE values for Traminette grown in our training system trial at Winchester. Roughly speaking, the MLTE value is the temperature that would be predicted to kill approximately 50% of the buds in the field. The data were collected from the first of September through mid-December of 2005. The daily minimum air temperature (°F) is shown as a continuous line with values on the left-hand axis. Our first fall frost occurred on 6 November, which would be day 67 on the bottom axis of Figure 1 (red arrow). Coupled with a relatively warm, dry fall, the late frost date made for excellent cold-acclimation conditions.

The interesting part of the Figure 1 is the open and closed circles. These represent the MLTE values for Traminette grafted to C-3309 rootstock (open circles) and for Traminette grown on its own roots (closed circles), as measured on five different dates, from mid-October through mid-December 2005. For the last date shown (13 December), the MLTE values were -9.8°F (grafted) vs. -8.5°F (own-rooted). The spread between the two was even greater in November. Crop levels were similar with grafted and non-grafted vines - about 6.8 to 7.0 tons/acre with divided canopy training, and 5.0 to 5.5 tons/acre with VSP (non-divided canopy) training. Two points are made. For one, the Traminette vines, whether grafted or not, would tolerate sub-zero field temperatures at this point in winter and would not be expected to sustain significant bud injury unless temperatures approached -10°F. This pattern should persist unless we have prolonged (many days) periods of warm, deacclimating temperatures (> 50°F). The second point is that grafting appears to confer some added cold-tolerance to Traminette. I won't, for now, speculate on the mechanism of that increased hardiness, but it is interesting to note that grafting has also reduced the incidence of bunch rots with Traminette, a response that we discussed at the ASEV/Eastern Section meeting in St. Louis, MO this summer.

Aside from the Traminette cold hardiness comparison, Kay has also been testing Viognier cold hardiness on a bi-weekly basis. At mid-December, Viognier buds exhibited MLTE values of -7.0 to -9.0 °F, with some minor variation due to training system. These are good values - Viognier is, afterall, a vinifera cultivar and we would not expect much greater levels of cold hardiness than this with vines grown at Winchester
