Einfluss von Thiophanat-Methyl und Methyl-Benzimidazol-2yl-Carbamat auf mykotoxinbildende <i>Fusarium</i> spp.
Abstract
Zusammenfassung
Bei der Untersuchung des Einflusses von Thiophanat-Methyl und Methyl-Benzimidazol-2yl-Carbamat auf mykotoxinbildende Arten von Fusarium spp. konnte beobachtet werden, dass Thiophanat-Methyl einen deutlich stärkeren Einfluss auf die Biosynthese der Mykotoxine als auf das Wachstum der Pilze aufwies und die Respiration von Fusarium spp. im Flüssigmedium unabhängig vom Myzelwachstum gehemmt wurde. Die Ergebnisse weisen somit auf einen zusätzlichen Wirkungsmechanismus von Thiophanat-Methyl in Fusarium spp. hin.
Abstract
Investigations into the effect of thiophanat-methyl and methyl-benzimidazole-2yl-carbamat on mycotoxinproducing species of Fusarium spp. showed that the influence on the biosynthesis of mycotoxins was more distinct than on the growth of the fungi. Moreover Fusarium spp. showed a reduced respiration at certain levels of TM that was not associated with an inhibited growth. The data indicate that there may be a mechanism of thiophanat-methyl by which the mycotoxinformation of Fusarium spp. could be inhibited independant from the growth of the mycelium.
Keywords: Fusarium spp., thiophanat-methyl, carbendazim, mycotoxinproduction
