Liberibacter solanacearum

Liberibacter

Candidatus Liberibacter solanacearum was discovered in 2008 by a NZ team led by Dr Lia Liefting (MAF). It was subsequently found to be the cause of the debilitating potato disease 'zebra chip' that has affected the USA industry since 2000.

Liberibacter solanacearum is transmitted by the tomato potato psyllid and infects various members of the solanaceous family including:

  • potatoes
  • tomatoes
  • capsicum
  • tamarillo
  • chilli
  • cape gooseberry

After the discovery of Liberibacter, a phytoplasma, which is a bacteria-like organism similar to Liberibacter, was also found to infect potatoes.  We are also able to test this.

For testing of Liberibacter or phytolasma, we require either stems from plants or trees, tubers, fried potato or leaves. We can also test the psyllid vector (e.g. from sticky traps) to see if the population has acquired Liberibacter.
