Root rot inCampanula carpatica caused byPhytophthora cryptogea

This is the first record of root rot inCampanula carpatica as well as in the genus ofCampanula caused byPhytophthora cryptogea. An attack was observed in potted plants grown in a greenhouse on ebb- and flow benches and with recirculation of the nutrient solution. The fungus caused wilting of the leaves together with discoloration and rotting of the roots. Pathogenicity tests showed that the isolate ofP. cryptogea fromC. carpatica attactedGerbera jamesonii and vice versa. Treatment with the fungicide furalaxyl was able to reduce disease development.
