Oregon State University Presents: Cold Mitigation Workshop

Given the extreme weather conditions we have been experiencing in the Walla Walla Valley this last decade, a thorough understanding of cold damage to plants especially wine grapes and orchards is imperative, as is knowledge of how to avoid and deal with the effects of cold.

A stellar cast of internationally renowned experts have agreed to present their findings, insights and recommendations into cold damage mitigation for wine grapes and orchards. The speakers will be touring the Walla Walla Valley on Monday July 20 so opportunities exist for a on-site visit if you desire one. Please notify us if you would like to schedule a stop on their tour but please note that it will be on first come first serve basis.

 What we’ll learn:

  • Understand the different mechanisms of cold (frost and freeze) damage
  • Gain an understanding of how plants harden off going into winter (acclimation) and what you should do to enhance this
  • Role of ice-nucleation bacteria and what you should do to limit their role.
  • Use of low profile wind machines and other mechanical methods of dealing with winter freezes
  • Traditional methods for dealing  with frost in spring
  • Novel methods for avoiding frost damage by delaying bud break in spring
  • Renovation of cold damaged vines

Instructors: Dr. Imed Dami (Ohio State University); Dr. Kevin Ker (Brock University, Canada); Dr. Mark Battany (University of California Cooperative Extension, Obispo County); Dr. Glenn McGourty (University of California Cooperative Extension, Mendocino County)

Cost: $65 per person. (Please note that space is limited and that we will be accommodating people on a first come first serve basis) Book early to avoid disappointment.
