Blackleg on potato can be caused by either Pectobacterium or Dickeya species, and they often work together in different combinations to cause this disease. Blackleg can result in stem decay, severe seed decay and sometimes lack of plant emergence in severe cases. This Hort Innovation and RM Consulting Group (RMCG) factsheet provides information on managing blackleg in potato crops.

Management of rots, both in the field and post-harvest, is an ongoing challenge for potato producers. Agronomists Marc Hinderager and Dr Pieter Van Nieuwenhuyse discuss a trial that was set up to explore the effect of sanitisers and/or drying on the development of post-harvest bacterial soft rot in potatoes.

This Monitoring Psyllids and Psyllid Predators in Australian Potato Crops report by Tasmanian Institute of Agriculture (TIA) and Hort Innovation covers the different psyllid populations found and the levels of psyllid predators present.

This 2018 report looks at the available literature and information regarding species present in Australia. It also investigates the accessibility of accurate diagnostic tests.

This 2003 report found the most common cause of decay was identified as bacterial soft rot (Erwinia carotivora). Calcium fertiliser levels and tuber calcium content was explored in this report alongside the importance of sourcing clean certified seed.

This 2003 paper by SA Research &Development Institute delves into the postharvest washing of potatoes to find where bacterial soft rot originates and where it develops. The report suggests some ways in which soft rot causing bacteria can be controlled in this process.
