Abstract
Leaf spot diseases affecting wheat in Western Australia (WA) are yellow spot (Pyrenophora tritici-repentis), septoria nodorum blotch (Parastagonospora nodorum), and septoria tritici blotch (Zymoseptoria tritici). They are caused by 3 different fungal pathogens but the disease symptoms and biologies are similar.
Impact from leaf spot diseases vary greatly from season to season and between locations. They are a problem in continuous wheat crops in stubble retention (no-till) farming systems. For the most effective control, an integrated disease management (IDM) approach is required.
This page outlines the symptoms, diseases spread and risk factors, yield and quality losses, and management options for the leaf spot diseases affecting wheat.
