Powdery Mildew - Wheat
Powdery mildew is commonly found in the base of crops but it is only occasionally that it develops to be a problem.
Look out for:
- White surface patches.
- Small black spore cases
- Cool, cloudy and moist conditions
Initially seen as surface patches of white mycelium, powdery mildew develops to cover the entire leaf. Mature infections often have black spore cases present.
The disease is wind borne and thrives in cool, wet weather.
While normally modest, yield losses of 40% have been recorded.
