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%.
