UK Breakthrough in Nematode Control: GB Potatoes and CUPGRA Release Exclusive PCN Management Guide

A United Response to PCN: Science and Practice in One Guide

PCN: A Persistent Threat to Potato Production

Potato cyst nematodes (PCN), specifically Globodera pallida and G. rostochiensis, remain a major concern for UK potato growers. These soil-borne pests reduce yields, harm soil health, and jeopardize the economic sustainability of farms.

With the potential withdrawal of key nematicides, the need for alternative and integrated control measures becomes even more urgent.

A Science-Backed Guide for the Industry

GB Potatoes and CUPGRA, together with nematology experts from Harper Adams University, have launched an exclusive guide titled “Managing PCN in Great Britain”, available to members only.

The guide includes:

• Practical cultural control methods (e.g., crop rotation, cover crops)
• Biological and chemical control strategies
• Variety selection and resistance management
• Modern monitoring and diagnostic approaches
• Integrated and sustainable farming techniques

Free Fact Sheet for Wider Access

To support the entire industry, a freely accessible fact sheet summarizing key recommendations from the guide will soon be available to all growers. This provides a quick, informative snapshot of best practices for managing PCN.

Industry Leaders Call for Pragmatism, Not Extremes

As emphasized by GB Potatoes and CUPGRA leadership, “Total soil sterilization or years-long fallow periods are unrealistic in commercial farming. What we need are integrated, science-based approaches that help manage PCN populations over time.”

This guide equips growers with actionable strategies that combine modern crop protection, resistant varieties, and sustainable farming — reflecting the evolving nature of nematode management in the UK.

Potatoes News Perspective

With the global potato sector increasingly focused on sustainable practices (as regularly featured on potatoes.news), the UK’s approach to PCN management provides a valuable example. Countries like Russia, India, and Egypt facing similar nematode pressures may benefit from adapting these tools and insights to their local conditions.
