Erwinia chrysanthemi in Hungary on potato and maize
In Hungary, soft rots caused by Erwinia chrysanthemi (EPPO A2 quarantine pest) have been observed on maize and potato in some regions. In addition, the pathogen has been intercepted in 1987 and 1988 on imported symptomless seed potatoes. The incidence of the disease was respectively 15-40 % on potatoes, and 3-15 % on maize. Concerning potato crops, the authors felt that E. chrysanthemi has most probably been introduced into Hungary with imported seed potatoes, but noted that the sources of inoculum for maize crops remain unclear.
