Kiwifruit Psa

What is Psa?

Pseudomonas syringae pv. actinidiae (Psa) is a bacterial disease of kiwifruit vines, first identified on New Zealand kiwifruit orchards in November 2010. Psa carries no risks associated with human or animal health, and it does not affect plants other than kiwifruit vines.

How does Psa spread?

Psa is a transmittable bacteria, which means it can be carried via heavy rain, strong winds, on equipment, machinery, people and plant material.

Who is Kiwifruit Vine Health Inc. (KVH)?

KVH has taken over leadership of the Psa response from ZESPRI and MAF since December 2010. KVH is working with industry partners to develop and execute short- and longer-term strategies for managing Psa in New Zealand.

How do I limit the spread of Psa?

KVH has developed protocols and guidelines that should be followed whenever people, vehicles or machinery move on or off kiwifruit orchards.

The risks reject kiwifruit can pose to Northland

To ensure the on-going containment of the kiwifruit vine disease Psa-V all farmers must consider the risk of spreading Psa-V by the movement of contaminated plant/leaf material associated with reject fruit loads for animal feed. As these loads have the potential to harbour infected leaf/plant material Northland growers are preventing all inter-regional movements of reject fruit consignments as these can provide a pathway for the entry and establishment of Psa-V in Northland.

What can you do?

Please do not source kiwifruit for animal feed unless it is sourced from the same region you are located in.

To discuss any plans to buy reject kiwifruit, contact the local KVH regional committee:
