Assess the risk of rust
The main rust hazard
area in western Canada is the southeastern part of the prairies.
However, this region can expand into western Saskatchewan
towards the Alberta border in years of severe epidemics, such as
was experienced 1986. Although two thirds of the rust damage was
a result of sub-optimal management practices that delayed crop
maturity, 1986 clearly demonstrated the need for better rust
resistance in winter wheat cultivars. In order to manage this
level of risk, at least a moderately susceptible level of
resistance is advised for well-managed winter wheat. Where there
are known deficiencies in the management package, i.e., late
seeding dates, phosphate deficiencies, etc., a higher level of
rust resistance should be considered.
