The growing season is in full swing. As growers are busy doing canopy management in the vineyards and wine makers are preparing for the upcoming vintage, OSU faculty are working hard on their field research trials and extension programs to advance viticulture and enology research and education. We’ve been busy...
The growing season has come to an end and everyone is feverishly trying to harvest fruit before rain and/or frost, depending on the specific vineyard location throughout the state of Oregon. Here at OSU, we’ve been busy over the past few months providing programming to growers and winemakers. During August,...
Winter provides many opportunities for viticulture and enology programming across Oregon, the Pacific Northwest and beyond. The vines, although dormant, need pruning and the winery operations continue. This month, we’ve decided to focus on important considerations in both the vineyard and winery. An article on pruning operations by Dr. Patty...

As the dormant season progresses towards the beginning of the 2010 vineyard season, we prepared this newsletter to focus on viticulture topics in disease management and cover cropping.
With pruning taking place across vineyards in Oregon, Dr. Jay Pscheidt reminds vineyard managers to be on alert for canker diseases. Also,...
As the season progresses and all anticipate bloom, we hope you take the opportunity to read this issue. It is full of useful information on some pests of concern—both old and new—in the vineyard and winery: powdery mildew, grape rust mites, Spotted Wing Drosophila and Brettanomyces.
We include other useful...
In this August issue, we focus on the grape berry. Articles within cover topics of cluster thinning, berry ripening, harvest., and various pests that can damage berries. Also, we provide information about how to conduct vine nutrient sampling at véraison to be sure to keep up with your nutrient program....
Welcome to the September 2010 edition of OSU Vineyard Notes. We take this opportunity to make you aware of pest-related problems in the vineyard. This 2010 season has been a challenge for many, and the challenges do not stop here. Jay Pscheidt, OSU Extension Plant Pathology Specialist, reports on new...
We are happy to present a viticulture-based newsletter this quarter, focusing on some of the challenges that were apparent in vineyard management during 2010. While the Botrytis challenges are fresh in the minds of vineyard managers, Walt Mahaffee provides a summary of a replicated field trial using Botrytis sprays. Vaughn...

Specialty organic fertilizers used in organic vegetable production are expensive. So, from environmental and economic perspectives, growers want to maximize nitrogen (N) fertilizer use efficiency by the crop. This research was conducted to (1) determine sufficient N fertilizer rates for organic broccoli, (2) evaluate the efficacy of a specialty organic...
The recently emerged Grapevine Red Botch Virus (GRBV) impedes proper berry ripening primarily by reducing sugar accumulation and color development in red-fruited Vitis vinifera L. cultivars. To date, there is no recommended management strategy for virus spread or the impacts of the disease beyond removal and replacement of infected vines....
