Of all pests and diseases of potatoes in Great Britain, infestation by potato cyst nematodes (PCN), or eelworms, is the most damaging. Yield losses depend on pest populations, soil type and potato variety, with a range of 1–35% in trials, with infestations at 10–20 eggs per gram of soil.
Sampling and lab testing for PCN are vital, as, at low levels of infestation, no symptoms are seen in the field. This document provides a step-by-step guide to the sampling and testing process. If you have any further questions please contact your agronomist/advisor or your AHDB Knowledge Exchange Manager.
