Powdery mildew

Powdery Mildew


Powdery mildew is more common in barley than in wheat crops in Victoria. The powdery mildew that attacks wheat (Blumeria graminis f. sp. tritici) will not attack barley, and vica-versa. The disease is most common in early sown lush crops with adequate nitrogen nutrition. It is first observed during tillering, but does not normally persist beyond ear emergence. Losses in wheat in Victoria are rare.
