Abstract: Studies were carried out to test the sugar beet as a host for Clavibacter michiganensis ssp. sepedonicus (Cms), the causal agent of bacterial ring rot of potato. For that purpose field trails and greenhouse experiments were performed. At the field trails sugar beet was cultivated on plots, which were contaminated with Cms infected soil. Subsequently the plots were used for the cultivation of potatoes. Both, the harvested sugar beets and the potatoes, were tested in polymerase-chain reaction (PCR). Both, the sugar beets and the potatoes were tested negative for Cms.
In the greenhouse sugar beet was treated with Cms by cultivation in Cms contaminated soil, by direct inoculation into the plant or by indirect inoculation by watering with contaminated suspensions. In most experiments Cms could not be detected in sugar beet after 18 weeks, so it did not remain viable in the plant. But in one experiment after direct inoculation Cms was detected and reisolated in sugar beet. Additionally, no infection of sugar beet was observed via contaminated soil.
