LOOK OUT FOR:
Yellow
rust pustules
arranged in stripes
RISK FACTORS:
Cultivar choice
Cool, moist conditions
Stripe rust tends to develop earlier in spring, being favoured
by cool, moist conditions whereas leaf rust is more of a
problem in early to mid-summer.
Early infections of stripe rust are hard to distinguish from leaf rust
pustules scattered on the surface of leaves. Later stripe
rust pustules, which are quite yellow, form distinct stripes
whereas leaf rust pustules, which are brown, remain scattered
on the leaf.
Yield losses can be high, often in the order of 15-40%.
