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,...

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...

Full Text:: gall disease was found on cherry trees and raspberry plants in nurseries where K84 had failed to

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...

Isolation and Pathogenicity of Naturally Occurring Entomopathogenic Fungi to Clover Root Borer (Coleoptera: Curculionidae: Scolytinae), a Pest of Red Clover Seed Crops

Creator:: Lestari, Anis S.
Abstract:: Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...

Pathogenicity of Phytophthora species from Oregon waterways

Creator:: Navarro, Sarah M.
Abstract:: Described as one of the most destructive pathogens of agricultural crops and forest trees, Phytophthora is a genus of microorganisms containing over 100 known species. Phytophthora alni has caused collar and root disease in alders throughout Europe and a form of the species has recently been isolated in North America....

Flavor composition of transgenic raspberry bushy dwarf virus-resistant 'Meeker' raspberries

Creator:: Malowicki, Sarah Marie-Mahler
Abstract:: Raspberries have been popular since the time of the ancient Greeks. Red raspberries are cultivated throughout the world, particularly in the Pacific Northwest region of the United States and Canada. The raspberry bushy dwarf virus (RBDV) causes significant reduction in yield and crumbly fruit in raspberries, blackberries and raspberry-blackberry hybrids....

Integrated small broomrape (Orobanche minor Sm.) management in red clover (Trifolium pratense L.)

Creator:: Ross, Kyle C.
Abstract:: Small broomrape, a holoparasitic weed, is a relatively new weed introduction in the Pacific Northwest that has contaminated a limited number of red clover fields in Oregon. Greenhouse and field studies were conducted to evaluate small broomrape response to common crop and weed species in the Pacific Northwest. Host species...
