Surveillance for new forms of Psa

KVH has testing underway to learn more about the possible detection of a Psa variant on two properties.

Psa has been present in New Zealand for over 10 years and growers are now successfully managing this organism as part of their routine orchard practices. KVH regularly monitors for new forms of Psa and has robust processes in place to prevent spread if these were to appear.

Study of new and historical isolates of Psa allow us to look for changes or anything unusual. In a recent review of historical samples, a different variant was identified and as is routine, we are further investigating to learn more about the significance of this variant.

Psa remains a specified organism in our new Pathway Plan, which continues to provide the ability to manage the spread of new and existing forms of Psa should they be found. As a precautionary step the growers have been asked to manage movements of any risk items from these properties.

To address any potential risk KVH and Zespri have commissioned research to understand what this new Psa variant means for the kiwifruit industry and will re-commence Psa surveillance in spring. We will then provide more information about our research and surveillance when available.
