Response from nitrogen and chloride fertilization was measured
in field experiments on winter wheat (Triticum aestivum L. Em.
Thell. var. 'Stephens' and 'Yamhill') grown in western Oregon in an
environment with a range of susceptibility to take-all root rot
(Gaumannomyces graminis var. tritici Walker). Cropping sequences
and expected disease severity...
The use of fungicides for the control of foot rot of winter
wheat, caused by Pseudocercosporella herpotrichoides (Fron) Dei.,
requires a forecast of disease risk to optimize this management
practice ecologically and economically. Foot rot occurs in both
the mild, wet (100+ cm, ppt./year) annual cropped areas in western
Oregon,...
Take-all root rot (Gaeumannomvces araminis var.tritici) is
a major disease of wheat (Triticum aestivum) in western Oregon.
Control of take-all is dependent on management practices such as crop
rotation and soil fertility-plant nutrition relationships. The
objective of this study was to develop a bioassay that could measure
the influences of...
