The dwindling availability of insecticide seed treatment and nematicides has paved the way for pest control using entomopathogenic nematodes.

Potatoes are increasingly traded globally, raising the risk of spreading quarantined pests and diseases. Organizations like EPPO and national bodies regulate many of these threats, necessitating a unified approach to pest and disease management.

This year’s Hutchinsons Potato Demonstration Day, held at Worth Farms, Holbeach, Lincolnshire, focussed on potential solutions to address some of the key challenges faced by UK potato growers.

Climate change and genetic selection have brought root-knot nematodes further north in Europe and made cyst nematodes more difficult to control.

A pest never before seen in Latvia – the pale potato cyst nematode (Globoder pallida) has been identified in a Zemgale potato farm.

USDA’s Specialty Crop Research Initiative (SCRI) recently announced funding (USD 6.8M) for Potatoes and Pests – Actionable Science Against Nematodes (nicknamed PAPAS).

Potato industry challenges posed by PCN and blackleg were among the topics discussed at the recent Cambridge University Potato Growers’ Association (CUPGRA) annual conference.

Teagasc used its presence at this week’s World Potato Congress (WPC) to network with comparable organisations, in particular those undertaking similar projects regarding breeding new potato varieties.

With potato production in East Africa under increasing threat from the invasive and highly destructive potato cyst nematode (PCN) pest, an organic technology developed from banana plant waste material may well be the ultimate rescue.

After the Plant Health Centre led a working Group to identify a clear strategy for dealing with the Potato Cyst Nematode (PCN) crisis, a report was delivered to the Scottish Government.

A team effort led to Alberta being declared Potato Cyst Nematode (PCN) free – improving trade prospects for producers.

New research to tackle the growing scourge of Potato Cyst Nematode (PCN) has been identified by a specialist Scottish Government working group.

Mallorca has been exporting potatoes to the United Kingdom since 1927 and future exports are now guaranteed because the British Government has agreed to change the regulations and allow Mallorcan potatoes to be sold in the British market.

Demand for potatoes in eastern Africa has been growing steadily. This growth is driven in part by rising demand from the fast food industry and for processing into high value products such as crisps, chips and starch. Despite an increase of 60% in the area of cultivated land, production has been declining in Rwanda, Kenya and Uganda.

Harry van de Vijver, Germicopa, Quimper (F): 'Give us yellow-fleshed French-fry varieties with broad nematode resistance.'

Jörg Renatus, Europlant Holland, Heerenveen: 'We perceive a demand for robust, stress-resistant varieties with nematode resistance.'

Jos Bus, The Potato Company, Emmeloord: 'What you want to find in the end is a practical potato with a simple user manual.'

WSU plant pathologists Kiwamu Tanaka and Cynthia Gleason are exploring novel approaches to protect the potato crops against nematodes and scab - mobilizing nature itself.
