Recently, following a working group on PCN, a report entitled ‘Potato cyst nematode (PCN) and the future of potato production in Scotland’ was submitted to Scottish Government highlighting the PCN problem in detail and outlining practical recommendations for its reduction.
Scottish Government agreed to fund in full the recommendations in the report and this project will aim to:
• develop resistance markers to PCN to inform breeding programs,
• introduce diploid breeding strategies to generate PCN resistant varieties relevant to the Scottish fresh potato market,
• improve the understanding of the mechanisms of PCN tolerance in potatoes,
• methods of groundkeeper control and management,
• novel and improved IPM tools for PCN management,
• create a decision support tool for PCN control in Scotland, building upon the AHDB’s PCN calculator
• A review of possible interventions to include a review of PCN management in other countries to inform the work packages below:-
• Modelling future risks of both G. rostochiensis and G. palida using interventions identified in the review and climate scenarios.
• Grower behaviours and attitudes to interventions, to include input from industry stakeholders.
• An economic analysis of likely impact in Scotland based on a range of possible interventions.
Impact: A clearer understanding of possible control options, economic impacts of available interventions and the likelihood of growers and buyers adopting new resistant varieties, altering rotation practices or any other interventions such that recommendations on best strategies (including statutory controls) can be made.
Following a Ministerial round table meeting on PCN in June 2020, a working group of over 50 potato industry, government and academic partners was set up (from both Scotland and the wider UK) to identify a clear strategy for dealing with the PCN crisis. Following over 320 person hours of scheduled meetings, plus many days of personal discussions, recommendations for how to combat the growing threat of PCN to the Scottish potato industry have been proposed.
This project has: i) reviewed possible PCN interventions; ii) modelled future risks; iii) surveyed grower behaviours and attitudes to interventions; and iv) conducted an economic analysis of likely impact in Scotland based on a range of possible interventions.
