Integriertes Nematodenmanagement in Fruchtfolgesystemen mit Zuckerrüben

The development of modern methods and techniques for the determination of infestation and prediction of damage is crucial for an integrated nematode management. Perspectives for a better prediction of nematode damage are generated by the combination of efficient methods for nematode sampling and nematode extraction from soil samples with non-destructive methods to localize and demarcate areas that show a higher infestation risk in the field. A lower reproduction potential of Heterodera schachtii by cultivation of oilseed rape compared with sugar beet is realistic, if volunteer oilseed rape is controlled in sufficient time. The use of nematode-tolerant sugar beet cultivars offers higher yield stability at high yield level. Not much is known about possible multiplication potentials for H. schachtii using such varieties short and long term. The potential of biological control of nematodes is supported by a better understanding of complex phenomena like soil suppressiveness. Methods with good prospects under controlled conditions like biofumigation need to be further developed to achieve a better efficiency in the field.
