Distribution of Phytophthora rubi and Pratylenchus penetrans in Pacific Northwest Red Raspberry (Rubus idaeus) Fields

Creator:: Kroese, Duncan R.
Abstract:: The Pacific Northwest produces over 95% of the nation’s processed red raspberries, valued at over $65 million. Two of the major soilborne pathogens effecting the production of raspberry in this region are the oomycete Phytophthora rubi, which causes root rot in red raspberry plants, and the plant-parasitic nematode Pratylenchus penetrans,...

Interactions of Amphorophora agathonica Hottes with raspberry viruses and resistant red and black raspberry

Creator:: Lightle, Danielle
Abstract:: In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...

Sequence determination and regional epidemiology of raspberry bushy dwarf virus (RBDV)

Creator:: Taylor, Susannah M.
Abstract:: Raspberry bushy dwarf virus (RBDV) is the sole member of the idaeovirus genus of plant viruses. It is a pollen-borne virus that economically impacts both red and black raspberries worldwide. Three strains of the bipartite RBDV have been reported. The common strain found in North America, South America, Australia, New...

Response to fenamiphos, extraction techniques and population dynamics of Pratylenchus penetrans on western Oregon red raspberry

Creator:: Lolas, Mauricio
Abstract:: The effects of fenamiphos on soil and root populations of Pratylenchus penetrans were evaluated in four red raspberry cv. Willamette fields in Northwestern Oregon. Field 1 was a silty clay loam with 53% organic matter (OM). Field 2 and 3 were silty loam soils with 3.25 and 2.55% OM, respectively...

Evaluation of genetic diversity in wild populations of black raspberry (Rubus occidentalis L.)

Creator:: Dossett, Michael
Abstract:: In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred, in part, by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are...

Isolation of putative pAgK84 transconjugants from commerical cherry and raspberry plants treated with Agrobacterium radiobacter strain K84

Creator:: Lu, Shu-Fen
Resource Type:: Masters Thesis
Full Text:: gall disease was found on cherry trees and raspberry plants in nurseries where K84 had failed to

Characterization, epidemiology, and ecology of a virus associated with black raspberry decline

Creator:: Halgren, Anne B.
Abstract:: The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...

Seasonal abundance, distribution, and migration of the clover aphid, Nearctaphis bakeri (Cowen) in red clover

Creator:: Dreves, Amy J.
Abstract:: Four sampling techniques were evaluated to estimate clover aphid, Nearctaphis bakeri (Cowen), abundance in red clover fields in the Willamette Valley. The Berlese funnel method detected one to four times more aphids than other sampling techniques. Visual assessment often underestimated the high aphid densities during the flowering and seeding of...

Arthropod community structure in regenerating Douglas-fir and red alder forests : influences of geography, tree diversity and density

Creator:: Schaerer, Brett L.
Abstract:: The structuring of canopy arthropod communities was reviewed and investigated in relation to tree species diversity and its component factors, interspersion of different species and density of each tree species. Fifteen treatments of Douglas-fir (Pseudotsuga menziesii) and red alder (Alnus rubra) (various densities and proportions of each) were randomly assigned...
