Abstract:: Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. This publication provides a description and information on biology,...

Creator:: Schroeder, Jan-Marie
Abstract:: Fluctuations in population density of Pratylenchus sp., Trichodorus sp., and Xiphinema americanum s. 1. in three blueberry fields were determined monthly for one year. Pratylenchus densities were greatest in August and least in October. Three distinct periods of population growth occurred; during January, April, and between June and August. Trichodorus...

Creator:: Oregon State University. Extension Service and Smiley, Richard W.
Abstract:: Nematodes are roundworms with complex organ systems. They occur worldwide in all environments. Most species benefit agriculture by contributing to decomposition of organic matter and are important members of the food chain. Some species are parasitic to plants or animals. More than 2,000 of the 20,000 identified nematode species are...

Full Text:: Plant-parasitic Nematodes Affecting Wheat Yield in the Pacific

Creator:: Lawrence, Caitlin E.
Abstract:: Pacific Northwest prairies have become significantly reduced in extent, and in the Willamette Valley of Oregon, less than one percent of native upland prairies remain. Many species have been impacted by this extreme loss of habitat, including Castilleja levisecta (golden paintbrush), a threatened hemiparasitic forb species endemic to the Pacific...

Creator:: Cerruti, Natasha R.
Abstract:: After an unusually high incidence of Fusarium canker was observed in commercial hop fields of the Pacific Northwest, field surveys were conducted and revealed that canker incidence ranged from 20 to 60% of bines sampled in six commercial fields, as well as wide-spread Hop stunt viroid infection in these six...
