Spatial Population Dynamics of Potato Cyst Nematode Globodera Rostochiensis (Woll.) in Sandy and Peaty Loam During the Course of a Growing Season

Open publisher page 8 citations

Abstract

Changes in the number of all stages of potato cyst nematode, Globodera rostochiensis (Woll.) were followed in potato roots and two soil types for the duration of a growing season. The first population changes were seen to occur close to the planting depth, the timing and scale of the changes at other depths being correlated with the cysts' position relative to the seed. Evidence was found for a potential second generation which did not materialise in the roots, probably because of the maturity of the plants. Cysts from the furrows showed a carry over of approximately 70% .
