Psa-V

Psa-V

Psa-V Pseudomonas syringae pv. actinidiae (Psa) is a bacteria that can result in the death of kiwifruit vines. It was first discovered in New Zealand in November 2010 and rapidly caused widespread and severe impacts to New Zealand's kiwifruit industry.

Past Psa-V resources


The kiwifruit industry has been at the forefront of biosecurity and pest management for many years. This proactiveness and future thinking continues with implementation of of the industry’s Pathway Management Plan.

With the introduction of the new Plan, the industry moved into a new phase of Psa protection and longer-term management from 1 April 2023.

Psa continues to be managed in the same way, by the industry working collectively at an orchard, regional and national level to reduce spread and impacts, and ensure best practice for day-to-day management of the pathogen on-orchard.

To ensure the very best support for growers moving forward through this new phase there are changes in some responsibilities. To be consistent with other crop protection responsibilities for pests already present in New Zealand, Zespri now coordinates support to growers to manage the impact of Psa on-orchard and updates industry resources and tools to promote Psa management best practice. View these on the Zespri Canopy website here.

As the industry's dedicated biosecurity body KVH retains all high-risk management of Psa and preparedness for any new variants.


Psa resources produced by KVH pre 1 April 2023

Below you will find several Psa resources and pieces of information and advice that were produced by KVH prior to the 2023 move into a new phase of longer term management and the introduction of the Pathway Management Plan.

If you have any questions about these resources and their past usage, please contact KVH at [email protected] or 0800 665 825.

The Biosecurity (National Psa-V Pest Management Plan) Order 2013 commenced Friday 17 May 2013 for a 10 year term. Detailed information is available here, or you can read the KVH summary.

Psa protectant products

Information about the five categories of products (copper, bactericides, elicitors, biological control agents, and CPPU).

Psa orchard hygiene posters

English - Maori - Hindi - Nepalese - Punjabi - Samoan - Spanish - Thai - Simplified Chinese - Tongan

A short instructional hygiene video was also produced in English and Punjabi.

Psa risk compass infographic posters

The Psa-V risk compass provided infographic-style poster presentations of key issues for consideration when developing and implementing strategies for managing Psa-V.

Male management

Male vines appear more susceptible to Psa than female vines. Choice of cultivar and careful cultural management of male vines are important in minimising productivity impacts of Psa on orchards.

Psa research and development

KVH and Zespri innovation established in early 2011 a global research and development programme that enlisted the best scientific minds globally to provide solutions. This created a toolbox for managing Psa, and our understanding of appropriate plant husbandry progressed significantly.

Between 2011 and 2023, many reports and papers were published for the kiwifruit industry on the KVH website.

Successful end to fruit fly response on Auckland’s North Shore

Controls on the movement of fruit and vegetables in the Auckland North Shore suburb of Birkdale have been lifted after no further evidence of the Oriental fruit fly was found in the area. The decision to end the operation follows seven weeks of intensive fruit fly trapping and inspections of hundreds of kilograms of fruit, with no further detections. Residents and businesses in the affected area are being thanked for their support of the movement controls, keeping an eye out for fruit flies, and safely disposing of fruit in provided bins. The support from the North Shore community has been vital to protect our industry and the wider horticultural sector. National routine surveillance will continue, with New Zealand’s system of nearly 8,000 fruit fly traps spread across the country, set for three exotic fruit fly species of concern: the Queensland fruit fly, Mediterranean fruit fly and Oriental fruit flies. KVH thanks industry personnel from APAC who collaborated with us on fruit fly response activities in Birkdale.

We have a new Snapshot podcast online, where we chat with Ryan, Chief Quarantine Officer for the Ministry for Primary Industries, about the work his teams does across biosecurity. Ryan manages the Tauranga, Hamilton, and Northland regions – there are biosecurity teams in all three regions – and in the chat we focus on the way they manage cruise ships, transitional facilities, and various partnerships that they have with KVH and the kiwifruit industry. The Snapshot podcasts are free and available now on SoundCloud and Apple iTunes.
