Gary Chastagner, Washington State University's Christmas Tree Extension Specialist and one of the leading pathologists for this crop in the world, was a featured presenter at the recent Christmas Tree Disease Management Workshop in Clackamas County, May 27, 2009. The all day event, attended by 25 growers, provided a full day of instruction by Gary on disease diagnosis, life history and control. One half of the session was classroom and the other half in the field.
The workshop was organized by the Oregon State University Extension Service and held at OSU's North Willamette Research and Extension Center near Aurora. Support for the workshop was provided by the Preston Forestry Research fund, a gift to OSU to support pest management research and education.
