  • Cereal cyst nematodes : biology and management in Pacific Northwest wheat, barley, and oat crops 
    Oregon State University. Extension Service; Washington State University. Extension; United States. Dept. of Agriculture; University of Idaho. Extension; Smiley, Richard W.; Yan, Guiping; Smiley, Richard W; Yan, Guiping; Oregon State University. Extension Service; Washington State University. Cooperative Extension; University of Idaho. Cooperative Extension Service; United States. Dept. of Agriculture; Pacific Northwest Cooperative Extension ([Corvallis, Or.] : Oregon State University, Extension Service ; [Pullman, Wash.] : Washington State University Extension ; [Moscow, Idaho] : University of Idaho Extension ; [Washington, D.C.] : U.S. Dept. of Agriculture, 2010-10)
    Cereal cyst nematodes reduce yields of wheat, barley, and oats in the Pacific Northwest states of Idaho, Oregon, and Washington. It is estimated that these pests reduce wheat profitability in these states by at least $3. ...
  • Controlling root and crown diseases of small grain cereals 
    Oregon State University. Extension Service; Smiley, Richard W.; Cook, R. James, 1937-; Paulitz, T. (Timothy) (Corvallis, Or. : Extension Service, Oregon State University, 2002-02)
    Farming systems, equipment, climate, and topography vary widely in the Pacific Northwest. Simple prescriptions for managing root diseases are not possible with so much diversity. However, certain general practices can h ...
  • Controlling root and crown diseases of small grain cereals 
    Oregon State University. Extension Service; Smiley, Richard W.; Paulitz, Timothy; Marshall, Juliet ([Covallis, Or.] : Oregon State University Extension Service, 2012-11)
    This publication describes practices to manage and minimize losses from root and crown diseases of wheat and barley throughout the Pacific Northwest.
  • Detection and Quantification of Pratylenchus thornei in DNA Extracted from Soil Using Real-Time PCR 
    Yan, Guiping; Smiley, Richard W.; Okubara, Patricia A. (American Phytopathological Society, 2012-01)
    The root-lesion nematode Pratylenchus (hornet is one of the most important pests restricting productivity of wheat in the Pacific Northwest (PNW). It is laborious and difficult to use microscopy to count and identify the ...
  • Long-term management effects on soil productivity and crop yield in semi-arid regions of Eastern Oregon 
    Oregon State University. Agricultural Experiment Station; United States. Agricultural Research Service; Columbia Basin Agricultural Research Center; Rasmussen, Paul E.; Collins, Harold P.; Smiley, Richard W. (Corvallis, Or. : Agricultural Experiment Station. Oregon State University., 1994-06)
  • Plant-parasitic nematodes affecting wheat yield in the Pacific Northwest 
    Oregon State University. Extension Service; Smiley, Richard W. (Corvallis, Or. : Extension Service, Oregon State University, 2005-05)
    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 cha ...
  • Root-lesion nematodes : biology and management in Pacific Northwest wheat cropping systems 
    Smiley, Richard W.; Oregon State University. Extension Service; Washington State University. Extension; University of Idaho. Extension; United States. Dept. of Agriculture ([Corvallis, Or.] : ǂb Oregon State University, Extension Service ; [Pullman, Wash.] : Washington State University Extension ; [Moscow, Idaho] : University of Idaho Extension ; [Washington, D.C.] : U.S. Dept. of Agriculture, 2010-03)
    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 decompos ...
