Description of Data
This is a polygon dataset of Agricultural Land Parcels in Northern Ireland that are infected with Potato Cyst Nematodes- a serious pest of potatoes. The Plant Health Order requires that no potatoes are grown on this land and that infected soil is not moved so as to contaminate other land.
Potato Cyst Nematode
The pest Potato Cyst Nematode (PCN) is known locally as ‘eelworms’. It is, potentially, the most serious pest affecting potato crops in Northern Ireland as it can cause virtually total economic loss of the crop if not managed appropriately. Eelworm is a microscopic soil-borne worm that destroys the root system of the potato plant resulting in severe yield loss. Once established in land it takes years (often 20 years or more) before it eventually declines and is undetectable. It is readily spread from field to field by direct movement of soil or by soil attached to equipment such as harvesters and by planting potatoes infected by the pest.
DARD receives about 350 requests per year from DOE in connection with soil movements (eg a new road being built) to establish if particular fields are infected. Puttting this data onto to the Geohub means, that the DOE can see for themselves if infestation has been detected or not.
Some facts about Potato Cyst Nematode (PCN)
- PCN is a microscopic worm that invades potato roots to feed, and at large infestation levels a noticeable yield reduction occurs, generally along with yellowing and wilting of foliage.
- PCN occurs as two species; Globodera rostochiensis and Globodera pallida, within which several pathotypes (races) have been identified throughout the world. In Northern Ireland G. rostochiensis (strain Ro 1) is the most common form.
- PCN can multiply very rapidly (up to 60 fold per year) and is very persistent in the soil (up to 20 years).
- Many older ware varieties still grown in Northern Ireland (Home Guard, British Queen, Pentland Dell, Kerr’s Pink, Dunbar Standard) are all very susceptible to PCN attack.
- Many newer potato varieties including some of those popular with organic producers are resistant to G. rostochiensis (Ro 1), and resistance to all forms of PCN is becoming more common in new varieties.
- At present PCN levels in ware ground are very low and a one year in five rotation, or longer, helps to maintain this.
