The results from the 2022 demonstration trial held at Barnyards by kind permission of Neill Smith were presented by Phillip Burgess (scottishpotatoes.org) and Eric Anderson (Scottish Agronomy).

Presentation by Steven Thomson from SRUC with information about the economics of the potato industry and PCN. 

Development of a decision support system is included in the project and Jim Wilson led the workshop on ideas and inclusions for a DSS.

This presentation from the conference shows the work being done at the James Hutton Institute to help identify and include PCN resistance in potato breeding. 

John Jones, Vivian Blok and Glenn Bryan from the James Hutton Institute have produced a review about tolerance to PCN. The review is summarised here and highlights how tolerance to PCN differs from resistance (which are often confused), current understanding and ongoing research regarding this important trait. 

This grower story is about Neill Smith, a potato grower based in Angus. Neill uses an integrated pest management approach for PCN which includes a combination of PCN soil sampling, applying nematicides, growing resistant varieties and an oilseed radish cover crop, and controlling groundkeepers. 

A working group comprised of over 50 potato industry, government and academia partners was set up to create a strategy for dealing with PCN. The resulting report written by Ian Toth, Fiona Burnett, Philip Burgess, Colin Herron, Jon Pickup, is published on the Plant Health Centre website and includes the four recommendations below that the group proposed: 

1. Increase the potato sector’s capability and motivation to implement change…

The AHDB PCN Grower Guide covers many aspects of PCN from background and prevalence to distribution, sampling and control methods. This guide was published in 2018 by AHDB Potatoes.
