Potato cyst nematodes (Globodera pallida and G. rostochiensis) and beet cyst eelworms (Heterodera schachtii) are difficult to control and therefore a serious threat of plant production in Germany due to high crop failure. The processing of potato and sugar beet yields in several hundred thousand tonnes of soil adhering on the crops after harvest. Soil residues are hard to avoid in the process of crop harvesting and could often contain plant pathogens as nematodes. While the spread of cyst nematodes is limited for planting material due to strict controls of field sites for planting material production, the dispersal of these pathogens by the uncontrolled introduction of soil residues from potato and sugar beet production into field sites remains as one of the most serious problems. Currently the introduction of soil residues is mainly responsible for the critical infestation status of these pathogens in Germany. The proposed research project aims the optimization of treatment procedures for disinfestation of soil residues from potato cyst nematodes and beet cyst eelworms. Therefore, treatments of (i) anaerobic soil disinfestation, (ii) soil inundation, (iii) composting, (iv) heat treatment using solarisation, (v) micro wave treatment, (vi) ozonization treatment and (vii) beta irrigation should be tested for their applicability. The tests should be performed in two stages (i) by determination of the application dose using nematode cysts free from soil residuals, and (ii) by application of the treatment procedures for soil residues artificially infested with reference nematode material. A second research focus will be the determination of nematodes viability and developmental capacity using different biological, biochemical and molecular approaches. The outcomes of the project should provide the possibility to recycle soil residues free from pathogens into agricultural used field sites.
