Beginning in mid-2014, this three-year project was tasked with studying bacterial diseases of onion crops in order to improve understanding of their introduction, spread and survival – and in turn help build the industry’s capacity to manage them. There was a particular focus on bacterial blight of leek, which affects onions and shallots and is caused by the bacteria Pseudomonas syringae pv. Porri, or ‘Psp’.

This project has been funded by Hort Innovation, using the research and development levies listed below and contributions from the Australian Government. Hort Innovation is the grower-owned, not-for-profit research and development corporation for Australian horticulture.
