Canterbury Potato Liberibacter Initiative (CPLI)

Funded by: CPLI.

Project Status: Current

Date of latest update: 17th October 2021

Project Overview

Canterbury Potato Liberibacter Initiative (CPLI), is a project created and funded by a committee of Canterbury growers and processors, with in-kind support from Potatoes New Zealand.

CPLI was formed in August 2021 by like-minded farmers and industry representatives to combat the devastating impact of the Liberibacter (Lso) bacterium which causes Zebra-chip in potato crops.

The issue is very clear and although the control measures and agronomy of Tomato Potato Psyllid (TPP) has made improvements, the incidence of Zebra Chip in the processing crop has increased and detection levels in potato fields have remained high.

It’s clear that current strategies and chemical programs are not solving or reducing the Zebra-chip impact for growers, seed growers and processors. The CPLI committee all agree there is a major knowledge gap with Lso. Although TPP is the carrier of Lso, Lso is affecting the quality of our potato crop.
