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.

Psa-V

Psa-V is a bacterial disease of kiwifruit vines and a major threat to the New Zealand kiwifruit industry. It carries no risks to human or animal health and does not affect plants other than kiwifruit vines.

First detected on a Te Puke orchard in November 2010, Psa has since been identified in numerous kiwifruit growing regions across New Zealand. Growth of Psa bacteria outside/inside kiwifruit vines can result in leaf spotting, cane/leader dieback and, in extreme cases, vine death accompanied by the production of exudates.

Since it's initial detection a significant amount of funding and resource has gone into an ongoing Psa-V research and development programme to better understand and manage the disease.

ACCESS THE ZESPRI WEATHER & DISEASE PORTAL

This online, weather-based decision support tool assists growers with orchard management in a Psa environment. 

Weather station data and weather forecast information is combined to provide customised access to unique weather information, disease information and interpretations. 


Based on the programme's results (combined with on-orchard experience) best practice advice and resources are developed and used by the industry, working collectively at an orchard, regional and national level to reduce Psa spread and impacts, and ensure day-to-day management of the pathogen. This information is produced and co-ordinated by Zespri, and is available online here.

As the kiwifruit industry's dedicated biosecurity agency, KVH leads all high-risk management of Psa and preparedness for any new variants. As such, Psa remains a specified organism in the Pathway Management Plan,which ensures we continue to have the ability to manage the spread of Psa within New Zealand and respond to new forms of Psa should they be found.

Meet the team

In the last issue of the Bulletin, we started our meet the team series, sharing more about the roles we have, and how each of us interact with you, our readers and growers, in our day-to-day activities. This week, we introduce Anna Li. I’m Anna and I joined KVH in August 2024 as the Systems Coordinator. My role is to support KVH’s IT infrastructure and security and provide data and mapping support to the team. I also create practical new tools and systems for KVH that we can use for online services to growers, particularly around traceability. My background spans web development, software programming, and mapping. I have a horticulture certificate too, which gives me deep insights into pest and disease control within orchard management. Before joining KVH, I was a professional landscape architect – something I’m still really interested in. I worked on residential projects and large public spaces, and gained valuable experience in mapping, which I use to this day. I’m excited to be part of KVH and look forward to working with you all to support our growers.

Cruise season is upon us

The 2024/25 cruise season in New Zealand is officially underway, with 45 cruise ships set to make a total of 957 stops around the country. Four cruise lines that haven’t been here since pre-Covid times are also coming back. We often get questions from growers about Biosecurity New Zealand’s Recognised Cruise Line Programme (RCLP), which checks how cruise lines handle risks. Here’s a rundown of what’s covered in the programme: Refuse management – such as using steam to sterilise bottles and containers that have been used for food.Pest and provision management – ensuring things like live plants are treated, pest traps are checked, and there’s a solid plan for managing pests in provisions.Passenger management – for example, limiting the serving of whole fruit and honey, and making sure passengers get biosecurity information at least two days before arriving.Biosecurity awareness – this includes making sure crew members are well trained. Starting this season, operators with a good track record of compliance may be able to keep their approval status for up to three years for both topside and underwater biosecurity. Evaluations will still happen every year, and operators will need to meet strict standards to maintain their approval. Also, Biosecurity New Zealand is changing how they do audits - officers will now carry out checks throughout the entire cruise season, not just at the first port of arrival. In the Bay of Plenty, we also have the Port of Tauranga Biosecurity Excellence programme, which involves the Port, KVH, Biosecurity New Zealand, and other local industry and council working together to raise awareness with frontline staff and ensure there are no biosecurity incursions through the Port.
