Canadian Wheat, Barley, and Oat Stem Rust in 2006Dr. Tom FetchCereal Research CentreAgriculture & Agri-Food CanadaWinnipeg, MB

Environmental conditionsWeather conditions in 2006 were unfavorable for development of rust

Above average temperatures with very dry to near normal precipitation occurred in the Prairie region

Only trace amounts of stem rust were found throughout the Rust area

Rust area in western CanadaSKMBAB

Virulence of Stem RustThe stem rust population is surveyed annually to detect changes in virulence that may signify the appearance of new dangerous races. Samples are collected from production fields and trap nurseries of wheat, barley, and oat in the Rust area of Manitoba and eastern Saskatchewan. Samples also are obtained from trap nurseries across Canada through collaborators.

Virulence determinationUsed standard inoculation methods and the letter nomenclature of Roelfs and Martens (1988) for wheat

Used same inoculation methods for oat, but now changed to new letter code (Fetch & Jin, 2007) adapted from Roelfs and Martens
