Assessing Vineyard Cold Damages 

The 2019 winter was harsh and in some areas shattered records. At this point, there may not be a lot vineyards can do to prevent additional damage if steps have not already been taken. But at a minimum you want to move air around or prevent air from being trapped into a cold air pocket that frequently happens in vineyards.


Managing Powdery Mildew in the Vineyard 

The 2017 growing season in Washington was an unusual year for powdery mildew. Irregularly high soil moisture from abundant snow pack and rainfall combined with higher humidity from smoke and cloud cover to increase the threat of infection for many vineyards. In addition, many vineyards developed poor fungal management practices because of historically low risk in the area.


Grapevine Red Blotch Disease Management in the Vineyard 

Grapevine Red Blotch Virus (GRBV) can affect profitability of vineyards by up to $170,000 per acres over the lifespan of the vineyard. Many symptoms can result from GBRV depending on the varietal, but ultimately it causes increased sugar and acidity which affects the quality and ripening of the grapes. Wine makers rely on the consistency their grapes for a balanced flavor profile, making GRBV infected grapes of no value in the production process.
