Untersuchungen zur Pathogenität und Mykotoxinbildung von Fusarium sambucinum, dem Erreger der Trockenfäule an Kartoffeln
11 strains of Fusarium sambucinum were isolated from tubers with dry rot symptoms from three different depots in the Land Brandenburg and Saxony-Anhalt. All isolates produced diacetoxyscripenol in artificially infected potato tubers. Additionally, two isolates produced T-2 and HT-2 toxins as well. The virulence and mycotoxin formation of the isolates was dependent on the potato varieties 'Sieglinde' and 'Berber' used in the experiment. The amount of diacetoxyscripenol in diseased tissue was positively correlated with the virulence of the F. sambucinum isolate and the susceptibility of the potato variety as well.
