Southern Oregon Viticulture and Enology

Viticulture is a developing program at SOREC.  The priority mission of the program is to continually identify and respond to the technical and educational support needs of winegrape growers in Jackson, Josephine, and Douglas Counties.  As the program develops there will be opportunities to secure funding for demonstration and educational projects aimed to provide specific and broad support for the increasing number and diversity of grape growers in Southern Oregon.

The Program aims to achieve this objective by:

  • Collaborative relationships with vineyard managers.
  • Commercial grower inquiries. Contact the Viticulture Advisor with any inquiry concerning vineyard establishment and management. 
  • Information and technology conducted by OSU scientists around the state.
  • Educational outreach is achieved through class programs and one-on-one consultations.  
  • Rogue Valley Winegrowers Association resource and contact.

In addition to a talk by SOU’s Greg Jones, this all day event will feature speakers California and Washington who are some of the top experts in their area of expertise. 

  • Dr. Mark Greenspan – Advanced Viticulture, CA.  Greenspan will talk about monitoring vine water stress.  Dr. Greenspan has a Horticulture/Viticulture from U C Davis and a PhD in Agricultural Engineering also from U C Davis.  He is regarded as one of the world’s leading experts in winegrape irrigation and has written scientific and trade journal articles on the subject. In addition to his command of grapevine irrigation practices, he has extensive experience in vineyard mineral nutrition, crop load management, vineyard uniformity, grape maturation, weather, climate and viticultural technologies.  He frequently delivers presentations on numerous topics to his colleagues in the wine industry at venues ranging from small classrooms and vineyard tailgate meetings to large industry-wide symposia. Mark is a regular contributor to wine industry publications, including Practical Winery and Vineyard and Wine Business Monthly. He has penned a viticulture column for Wine Business Monthly continuously since 2005.
  • Dr. Kendra Baumgartner – USDA-ARS, Davis, CA     Dr. Baumgartner will discuss managing trunk diseases of grapevines.  Dr. Baumgartner’s background is in Natural Resources Conservation and Plant Pathology. In 1996, she received her Bachelor’s degree in Forest Biology from the College of Environmental Science and Forestry in Syracuse, NY. From 1996-2000, she trained as a plant pathologist at UC Davis. As a doctoral student at UC Davis, she studied the epidemiology of Armillaria root disease in California forests and vineyards. In 2000, she joined the USDA, ARS in Davis, CA.
  • Kevin Judkins – Inland Desert Nursery, WA     Judkins will speak on propagation and certification of clean plant material.  Kevin, along with his father and brother, own Inland Desert Nursery in WA and claims his firm is the largest grapevine nursery in Washington state, where conditions are significantly different than in California.  In the first place, almost all vines in that state are own-rooted since there’s no Phylloxera present—and frequent freezes can kill the tops of vines. Fortunately, Judkins said, “There’s no red blotch here, except for a few patches due to growers buying plant material from California.” He added, “Washington nursery plants have been tested completely free.” He said part of the reason is that Washington State University in Prosser acquired clean material that had gone through micro-shoot tip culturing from Foundation Plant Services at UC Davis, then performed the same process before releasing vines for propagation to Inland.
  • Dr. Kent Daane – UC Berkeley Parlier, CA.  Dr. Daane will discuss leaf hoppers and red blotch virus in vineyards and their management.  His education includes a in Ph.D. in Entomology from University of California, Berkeley and a B.A. in Zoology from the University of California, Santa Barbara.  He has studied the insect vector issues for red blotch and is recognized as a world expert in this area.  His primary interest is to develop Integrated Pest Management programs for Arthropods (insects and mites) that are based in sustainable agriculture practices, such as the biological control of pests using beneficial insects and mating disruption or pests using synthetic sex pheromones.
