The presence of PCN cysts, alive or dead, poses a phytosanitary risk and can prevent the valuable exports of bulbs. As growers are more than aware, it is a long-standing challenge for the potato industry. In the last decade, SASA has recorded a 187% increase in land infested with G. pallida, from 2,411ha in 2010 to 6,929 ha in 2021, while 15,737ha was found to be infested with G. rostochiensis in the same year. Surveys of land used for ware potato production show 41% of ware fields are infested with PCN. This joint project with leading research institutions and two grower co-operatives aims to investigate alternative cover crop options for managing soil borne nematode populations and reducing the viability of PCN. Most nematode management strategies are pre-cropping treatments, and the planting of cover crops, which are grown between harvest and sowing the next main cash crop, can reduce nematode populations. The field trials will evaluate brassica biofumigants and nematode trap crops which are ‘poor plant hosts’ that can significantly limit nematode multiplication and substantially reduce existing soil populations. “Performance is dependent on a variety of agronomic factors which we will be exploring,” explains PhD student, Vongai Chekanai, who is leading the research in Scotland, as well as carrying out experiments in England and the Isles of Scilly. “We know, for example, that French marigolds increased bulb yield in root lesion nematode-infested sites on the Isles of Scilly, but it doesn’t work for all species of nematode infecting narcissus.” Field experiments are currently underway at Grampian Growers’ sites near Montrose. Managing Director Mark Clark said: “The market is increasingly competitive and it’s essential that our yields and quality remain strong. The demand for nematode-free land for bulb and potato production at Grampian Growers becomes higher and more difficult each year. We are excited to see this research get underway and to be working with such a strong representation from the industry. We look forward to seeing the results and how we can integrate different measures to strengthen the work we are doing.” Key to establishing an effective strategy for managing the target nematode species is to ensure that beneficial non-target organisms are not affected, or soil function reduced. JHI has developed molecular tools to fully characterise beneficial nematode and microbial communities and will be using its cross section of methods to assess soil function and non-target community composition in the glasshouse and field trials.
