The need to identify a simple but accurate method of stripe rust assessment that best predicts host response prompted this investigation. The study was divided into two plot types, one protected with the fungicide Bayleton and the other unprotected. Ten winter wheat cultivars were used and evaluated. Grain yield, test...
Field and growth chamber experiments were conducted to
determine chloride effects on the progress of stripe rust disease
caused by Puccinia striiformis West., and to investigate turgor
potential as the mechanism of the chloride effect.
Seven winter wheat (Triticum aestivum) cultivars were
grown in the field in 1982 and 1983...
Genetic resistance is the most appropriate way to control diseases in crop plants. Resistance can be described as qualitative (involving a gene-for-gene system) or quantitative (with continuous distribution of disease levels). The relationships between different types of resistance remain obscure, as does the genetics of quantitative traits. The use of...

Hypersensitive response-like (HR-like) needle reactions to infection by the white pine blister rust pathogen, Cronartium ribicola, have been reported for several species of five needle pines native to western North America. The best-studied examples are in Pinus monticola and P. lambertiana. In these species a "needle spot" phenotype has been...
Wheat stripe rust (WSR), also called yellow rust of wheat (Tricitum spp.), causal agent Puccinia striiformis f.sp. tritici (Pst), is a foliar disease of major economic importance on wheat, especially grown in temperate locations. WSR causes major losses of wheat yield, estimated at nearly $ 1 billion per year, and...
