- Red leather leaf (RLL) is a common foliar disease that causes yield losses in milling and hay oats in the medium and high rainfall zones of Victoria.
- Avoiding planting of very susceptible rated varieties significantly reduces losses.
- Foliar fungicide applied at mid tillering (Z25) and early stem elongation (Z31) provided the best suppression of RLL.
- Foliar fungicide application also provided suppression of fungal saprophytes and reduced hay discolouration post hay cutting.
