Onion (Allium cepa) crops in Western Australia were surveyed for the presence of Sclerotium cepivorum (the cause of white rot), Puccinia porri (the cause of rust) and Urocystis cepulae (the cause of American onion smut). Nineteen properties representing the majority of onion producers in Western Australia were surveyed. The three pathogens were not detected. Information collected provides knowledge to industry leaders on disease status and reasons to maintain import barriers on the basis of disease area freedom.
