Potato cyst nematode and Rhizoctonia: a destructive partnership

An account of evidence supporting the hypothesis that potato cyst nematode attack increases the susceptibility of potatoes to stem canker.

Year of Publication2009

Trials in plots infested with varying populations of potato cyst nematode and innoculated with Rhizoctonia solani demonstrated a clear relationship between nematode density and the incidence of stem and stolon canker caused by the fungus. Further studies suggested that the release of nutrients from the root as a result of nematode damage caused this effect and that canker incidence is reduced by nematicide treatment of the soil.
