Red leather leaf (RLL), caused by the fungus Neospermospora avenae, is the most common and severe foliar disease of oats in south-eastern Australia, and is also present in Western Australia (WA). It is favoured by wet and cool seasonal conditions, and is typically found in the medium and high-rainfall zones where it causes significant losses if unmanaged.
