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...

Population dynamics, extraction, and response to nematicide of three plant parasitic nematodes on peppermint (mentha piperita L.)

Creator:: Merrifield, Kathryn J.
Abstract:: The efficiencies of wet sieving/sucrose centrifugation (WS/SC) recovery of Pratylenchus penetrans (59 %), Paratylenchus sp., (80 %), and Criconemella xenoplax (66 %) were established. Baermann funnels (BF) recovered significantly more P. penetrans (p = 0.01) and significantly less (p = 0.01) C. xenoplax than did WS/SC. While densities of P....

Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:: David, Nicholas L.
Abstract:: Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

Comparison of Meldola’s Blue Staining and Hatching Assay with Potato Root Diffusate for Assessment of Globodera sp. Egg Viability

Creator:: Kroese, Duncan, Zasada, Inga A., and Ingham, Russell E.
Abstract:: Laboratory-based methods to test egg viability include staining with Meldola's Blue and/or juvenile (J2) hatching assays using potato root diffusate (PRD). These two methods have not been tested under identical conditions to directly compare their assessments of Globodera egg viability. Using two bioassay strategies, cysts from a Glabodera sp. population...

Pathogenicity and Management of Plant-Parasitic Nematodes on Vitis vinifera in Oregon Vineyards : 1996-1997

Creator:: Pinkerton, Jack, Candolfi-Vasconcelos, M. Carmo, and Ingham, Russell
Abstract:: Survey data compiled in 1995 showed that plant-pathogenic nematodes that cause yield loss in California and European vineyards are found in over 85% of Oregon vineyards. In over 37% of the samples collected, population densities of Xiphinema wnericanwn (dagger nematode) and Criconenw1la xenoplax (ring nematode) were greater than levels known...

Distribution and Population Dynamics of Plant-Parasitic Nematodes in Oregon Vineyards, and Their Effects on Vine Growth [1995-1996]

Creator:: Ingham, Russell E., Forge, Thomas, and Pinkerton, J. N.
Abstract:: Objectives 1. Survey Oregon vineyards for the presence, identity and abundance of plant-parasitic nematodes. 2. Relate the distribution and abundance of potentially pathogenic species to viticultural practices and site characteristics. 3. Evaluate the efficacy of Nemacur for reducing populations of plant-parasitic nematodes. 4. Document seasonal changes in the abundance of...

Pathogenicity and Management of Plant-Parasitic Nematodes on Vitis vinifera in Oregon Vineyards

Creator:: Pinkerton, Jack, Candolfi-Vasconcelos, M. Carmo, and Ingham, Russell E.
Abstract:: Plant-pathogenic nematodes that cause yield loss in California and European vineyards are found in over 85 % of Oregon vineyards. Population densities of Xiphinema americanun (dagger nematode) and Criconemella xenoplax (ring nematode) were found in 37% of vineyards at levels reported to cause > 10-25% loss in California vineyards. However,...

Distribution and Population Dynamics of Plant-Parasitic Nematodes in Oregon Vineyards, and Their Effects on Vine Growth [1993-1994]

Creator:: Ingham, Russell E., Strik, Bernadine C., Forge, Thomas, and Connelly, Ann
Abstract:: Objectives: 1. Survey Oregon vineyards for the presence, identity and abundance of plant parasitic nematodes. 2. Document seasonal changes in abundance of species of important plant parasites in order to identify optimum times for sampling. 3. Evaluate the efficacy of Nemacur for reducing populations of plant parasitic nematodes.
