| Abstract: | Aggressive pathotypes of Synchytrium endobioticum have been detected in Ukraine since 1963, mainly in the mountainous western part of the country. Potato crops are regularly surveyed to detect possible outbreaks. It has been observed that the aggressive forms attack the above-ground parts of the potato plant, as well as the underground parts, and this can assist detection. Possible foci are investigated by planting a standard replicated test with a susceptible cultivar and a cultivar resistant to the common pathotype. The distribution of S. endobioticum in Ukraine is summarized. Outbreaks are particularly found in potato plots adjoining farm buildings. |
