Adaptation of the Phytopathogenic Fungus <i>Microdochium nivale</i> to the Fungicides Tebuconazole and Fludioxonil.

ABSTRACT: The study investigated the adaptation of the snow mold causal fungus, Microdochium nivale, to the fungicides fludioxonil and tebuconazole. Analysis of intrapopulation diversity among 136 M. nivale strains from two Russian populations revealed no strains with high-level resistance to these fungicides. However, the strains exhibited considerable variability in their sensitivity to small fungicide doses. Fungicide sensitivity levels were not associated with virulence levels, whereas strains from different phylogenetic groups exhibited different predispositions to decreased sensitivity to tebuconazole and fludioxonil. In vitro adaptation experiments were conducted to assess: (1) the potential ability of M. nivale to acquire high-level resistance to these fungicides; (2) th
