Investigation on horizontal and vertical distribution of Heterodera schachtii in reclaimed soils and its effect on the damage of sugar beet crops
Project
Project code: JKI-A-08-1220
Contract period: 01.01.2011
- 31.12.2014
Purpose of research: Applied research
The Sugar Beet Cyst Nematode (SBCN) Heterodera schachtii represents the economically most damaging pest of sugar beet crops throughout large growing areas in Germany. Reclaimed land features a week antagonistic potential against Nematodes, due to its young biological development. Therefore, triggered by increasing temperatures, high population densities may build up within very short periods. Current investigations show a presence of H. schachtii in deeper soil layers of reclaimed and natural land which can not be detected by routine sampling of the topsoil. Preliminary findings confirm that deeply located nematodes can damage plants. There is a knowledge gab about the causes and factors which control this distribution and about possible population exchanges between Nematodes from top- and subsoil. The project intends to close this knowledge gab with special reference to the conditions of reclaimed land. Delivering the biological basis for adoption and development of biological control methods against nematodes, the project contributes to the improvement of integrated pest management in field crops. The efficiency of biological control e.g. using resistant catch crops could be reevaluated by means of rooting depth.
