Boxwood Health Workshop

Boxwood Health Workshop

OSU North Willamette Research & Extension Center

Presented By

SOLD OUT - Get added to the waitlist

Over a quarter of all boxwood (the #1 broadleaf evergreen shrub!) production in the US occurs in either Oregon, California, or Washington. A handful of pests challenge boxwood production and landscape management, but boxwood blight has emerged as a significant threat. This disease is even more troublesome in the PNW since symptoms appear to be more subtle as compared with other regions.

HRI, OAN, and AmericanHort are bringing experts to the Willamette Valley for a one-day workshop to talk about boxwood health. Specific topics include:

  • The latest updates on cultivar testing and control strategies of boxwood blight,
  • Insights from a major boxwood producer in the heart of boxwood blight country on how to start clean and stay clean
  • An overview of nursery production surveys for boxwood blight in Oregon
  • An update on APHIS efforts to prevent introduction of box tree moth to the US.

Representatives from Oregon Department of Agriculture will be on hand to discuss the Oregon boxwood cleanliness program. Bring your questions and come prepared to discuss!

 

RECERTIFICATION CREDITS

  • 10:00 - 10:15 a.m. - Break
  • 10:15 - 11:15 a.m.
    Session Two: Cultivar Resistance
    Dr. Jim LaMondia, Connecticut Agricultural Experiment Station

  • 11:15 a.m. - 12:00 p.m. - Session Three - To be announced soon
  • Noon – 1:00 p.m. - Lunch (box lunch included with registration)
  • 1:00 – 2:00 p.m.
    Session Four: First year scouting insights from the Oregon boxwood blight survey
    Dr. Jerry Weiland, USDA ARS
    This presentation will cover the range of boxwood blight symptoms that growers can expect to see, some other common diseases that may look similar, scouting strategies for detecting boxwood blight, and some common risks that may lead to explosive boxwood blight outbreaks, spreading the pathogen, or make detection difficult. I will also have a summary of the cultivars affected by boxwood blight.
  • 2:00 – 3:00 p.m
    Session Five: Boxwood Blight - A Managed Disease
    Bennett Sauders, Saunders Brothers Nursery
    After the record rainfall in 2018, Boxwood Blight became a common disease active in many gardens in the mid-Atlantic area of the United States. Along with the increased incidence of Box Blight, researchers have recently identified many commonsense ways to reduce the incidence of Box Blight at the nursery level. Bennett will explain Saunders Brothers’ Nursery “one two punch” of 1) BMP’s and 2) more tolerant cultivars to greatly reduce the chance of introduction and severity of Boxwood Blight.
  • 3:00 – 3:15 p.m. - Break
  • 3:15 - 3:45 p.m
    Session Six: Boxwood Blight Cleanliness Program
    Chris Benemann, Oregon Department of Agriculture
    In 2011, the Oregon Department of Agriculture created the voluntary Cleanliness Program In response to concerns of boxwood blight spreading among Oregon nurseries. The program emphasizes the working relationship between a nursery and their ODA inspector to effectively scout for the disease.
  • 3:45 - 4:00 p.m. - Closing Remarks and Discussion
