About Psa R&D

About R&D


KVH, in conjunction with Zespri Innovation, is leading a global research and development (R&D) programme into Psa-V.

The programme was established in early 2011 and has enlisted the best scientific minds globally to provide solutions for Psa-V.

We now have a tool box for managing Psa-V, and our understanding of appropriate plant husbandry has progressed significantly since 2011.

The Innovation team partners with around 20 global researchers to provide the best available expertise to the New Zealand kiwifruit industry.

Research projects and reports

The KVH/Zespri R&D programme has already produced a greater understanding of Psa, how it can be detected and how it can be managed. Our Psa knowledge develops through research projects and reports, and this will flow directly into KVH's practical Psa-management advice to growers, post-harvest operators and contractors.

Product testing

The KVH/Zespri product testing programme was developed to identify, rigorously test and get permission to use suitable products to help manage and control the spread of Psa-V. To date, more than 300 products have been tested for efficacy against Psa-V in the KVH/Zespri product testing programme.

Psa research library

This collection of scientific papers have been collated to provide information for private study purposes on topics relevant to the genetics, epidemiology and control, including bio-control, of the bacterial pathogen Pseudomonas syringae pv. actinidiae (Psa).  The links listed alongside each publication provide free access to pdf copies of the original scientific papers via the internet. Please note, we cannot guarantee that the original website hosting  a specific scientific paper will maintain free access indefinitely.
