Integrated Pest Management Options
Seed Treatment
Cool soil temperatures after seeding favours this disease. This
disease was quite important in Ontario wheat production, but the
incidence and hence its impact has been reduced substantially due
to the effectiveness of fungicide seed treatments. Use seed that
is free of bunt spores (black). Infected seed produces a "fishy"
smell.
