Cultural Practices

Cultural PracticesVineyard Nutrition
Just as in humans, nutritional balance within the vine is essential to consistent fruit quality and quantity. How do you balance nutrition in the vineyard? While the majority of nutritional management can be dealt with prior to planting, such as adjusting soil pH and organic matter, vineyard soil management is a continual process and requires monitoring to ensure healthy, productive vines. It's better to maintain proper soil health practices than to try to correct problems when leaf symptoms are visible. How can you keep an eye on vineyard nutrition? Soil and petiole testing will help you monitor nutrients available in the soil and in the plants. We recommend doing BOTH soil and petiole testing to verify that what you have available in the soil is actually getting into the vines. If a petiole test result indicates a deficiency, but soil test results indicate adequate levels of a nutrient, an alternative problem, such as improper soil pH or inadequate water drainage, could be the culprit.

Lake Erie Grape belt low temperatures in Feb 2015 reached -19 to -29 degrees F and this has caused variable damage to fruiting buds of grapevines. Viticulture Specialist, Luke Haggerty, and the CLEREL staff are evaluating the extent of bud damage from several vineyards across the region.

Winery Control Workshop- Stabilize your wine- Filtration, SO2 and Potassium Sorbate

August 2, 2016
Portland, NY

The use of sulfur dioxide and filtration to ensure bottle stability is a common practice within the wine industry. However, many producers also use potassium sorbate additions to inhibit re-fermentation of sweetened wines despite sulfur dioxide additions and utilization of sterile filtration. Enology experts from both Cornell and Penn State Universities will review how to best accomplish wine stability in the winery so that producers can improve production decisions. Attendees will walk away with a better understanding of how sulfur dioxide and potassium sorbate work in wine, what filtration accomplishes for wine stability, and how to implement quality control practices to ensure that wines are of minimal spoilage risk post-bottling. This workshop will also include a wine tasting to emphasize identification of the flavor associated with potassium sorbate additions and how it affects wine quality. The $50 includes all registration materials and lunch. This workshop is focused for winemakers, cellar staff, and enologists as it contains a production focus.

Frost Damage Identified

Frost Damage; Check your Buds!
Luke Haggerty
Viticulture Extension Educator
Lake Erie Grape Program

I traveled across the majority of the belt today (Friday April 29th) looking for frost damage from the frost event on April 26/27th. I found severe (90%) damage in parts of Cattaraugus, Erie and the north eastern part of Chautauqua counties. Damage in this area was not confined to low spots or frost pockets and could be found vineyard wide.
As I move west, most areas were unharmed. However... (a big however), I found frost damage in low spots and frost pockets. Areas I found damage in were along the railroad tracks in Portland and Westfield. Most of the damage in this area was confined to low spots and frost pockets.
My Message:
There are some hard hit areas with 90%+ primary damage.
Not all areas are damaged! Damage varies across the belt. Many unharmed vineyards.
The impact on yields will be variable.
I have not found any secondary bud damage. In some cases the secondary buds are already larger than the damaged primaries. So you need to evaluate your damage within the next week or so, before damage is obscured by the secondary shoots.
From the road the buds look good, but they may not be. You have to break, cut, or simply pluck off the bud to see the damage. Like winter damage you are looking for brown, black and crunchy buds.
If you have damage call your crop insurance agent.
