- Biology, Medicine
- Plant disease
- 1 June 2005
Crown rot of wheat and barley in the Pacific Northwest is caused by a complex of Fusarium pseudograminearum, F. culmorum, F. avenaceum, Bipolaris sorokiniana, and Microdochium nivale. Yield-loss… Expand
Pathogenic fungi associated with Fusarium foot rot of winter wheat in the semiarid Pacific Northwest
- R. Smiley, Lisa-Marie Patterson
- Biology
- 1996
Winter wheat plants and soil were collected from 288 nonirrigated fields in the semiarid Pacific Northwest during 1993 and 1994. Fungi associated with 5,390 crown and subcrown internodes from 10… Expand
Influence of glyphosate on Rhizoctonia root rot, growth, and yield of barley
- R. Smiley, A. Ogg, R. J. Cook
- Biology
- 1992
Time intervals between applying glyphosate to kill volunteer cereals and weeds and planting spring barley by direct drilling (no-till) into Rhizoctonia-infested soil were evaluated in field plots at… Expand
Soil C and N changes under tillage and cropping systems in semi-arid Pacific Northwest agriculture
- P. Rasmussen, S. L. Albrecht, R. Smiley
- Environmental Science
- 6 July 1998
Soils in semi-arid regions are highly susceptible to soil organic matter (SOM) loss when cultivated because of erratic yield, removal of crop residue for feed or fuel, uncontrolled soil erosion, and… Expand
Diseases of wheat in long-term agronomic experiments at Pendleton, Oregon.
- R. Smiley, H. Collins, P. Rasmussen
- Biology
- 1996
Diseases of winter wheat were evaluated over 3 years in four long-term (27- to 60-year) cropping system experiments. Disease incidence and severity were evaluated with respect to seasonal… Expand
Insights into the prevalence and management of soilborne cereal pathogens under direct seeding in the Pacific Northwest, U.S.A.
- T. Paulitz, R. Smiley, R. J. Cook
- Biology
- 1 December 2002
Direct seeding or no-till leaves the soil undisturbed, except where the seed is planted and the soil fertilized. It offers several advantages in small-grain cereal production, including reduction in… Expand
