LOOK OUT FOR:
Brown rust
pustules scattered
across the leaf
RISK FACTORS:
Cultivar choice
Cool, moist conditions
Early infections of leaf rust are hard to distinguish from stripe 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%.
