A supply and demand model for the sweet cherry industry in Wasco County, Oregon and two investment valuation models are used to value and assess the risk of investments in high-density sweet cherry orchard establishment and production from the producer perspective. The supply and demand estimation finds the cherry price...
The bacterium Pseudomonas syringae affects different crops worldwide. In the
Willamette Valley of Oregon, P. syringae causes bacterial canker in sweet cherry,
severely limiting its production. High grafting of susceptible sweet cherry cultivars to
resistant rootstocks is practiced in the Willamette Valley to reduce incidence of this
disease. The research...
The seasonal biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris), was studied to improve its management in Mid-Columbia area sweet cherry orchards. Overwintering OBLR larvae began to emerge from hibernacula at bud stage 2 (side green). Most overwintering larvae emerged from hibernacula within three weeks of first bud swell and...
Bacterial canker, caused by Pseudomonas syringae pv. syringae is
recognized as one of the greatest limiting factors in cherry production
in Oregon. Disease incidence may be decreased when susceptible
cultivars are high-grafted onto tolerant/resistant rootstocks. This
research was begun to develop a rapid screening method which could be
used to...
