Biology and management of the obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), in sweet cherry

Creator:: Omeg, Michael Kent
Abstract:: 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...

Biology of sweet cherry powdery mildew

Creator:: Calabro, Jill M.
Abstract:: The Pacific Northwest has become one of the nation’s premier sweet cherry, Prunus avium, production areas. As production of sweet cherries has flourished in Oregon and Washington, so has powdery mildew, caused by the fungus Podosphaera clandestina, which infects both foliage and fruit causing severe economic damage to growers. Sweet...

Relation of boron to cherry rosette disease in Oregon, and the possible implication in Oregon, and the possible implication of a virus

Creator:: Bolwyn, Bart
Abstract:: A disease of sweet cherry (Prunus avium L.) known as "cherry rosette" has threatened production of cherries in Oregon. In 1961 this disease was observed in widely separated orchards. Rosette occurred in isolated trees or in spreading patterns, often from identified single trees or from one section of an orchard....

Assays to determine tolerance of cherry rootstock to bacterial canker caused by Pseudomonas syringae pv. syringae

Creator:: Krzesinska, Elzbieta Z.
Abstract:: 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...

Development of an in vitro and modification of an in vivo bioassay to screen cherry genotypes for response to inoculation with Pseudomonas syringae pv. syringae

Creator:: Roche, M. Margaret
Abstract:: 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...
