Microdochium nivale , a wheat pathogenic filamentous fungus, appeared to be very sensitive in in vivo laboratory assays to fenpropimorph and tridemorph and to a lesser extent to fenpropidin, piperalin, and spiroxamine. It accumulated Δ 8 -sterols wh

The narrow-spectrum fungicide fenhexamid was introduced into French vineyards in 2000 to control grey mould caused by a complex of two cryptic species: Botrytis cinerea, the predominant species sensitive to fenhexamid, and Botrytis pseudocinerea, nat

In the mycelium of all the Fusarium species studied, the major sterol was ergosterol in the absence of fenpropimorph. In the presence of this fungicide fenpropimorph-sensitive strains, with the exception of F. nivale , accumulated mainly Δ 8,14 -ste

Publikováno v: Pest management science. 58(9)

Field strains of Botrytis cinerea Pers ex Fr, the causal agent of grey mould diseases, were collected from French vineyards between 1993 and 2000. Several phenotypes have been characterized according to the inhibitory effects of fungicides towards ge

The mechanisms of resistance to terbinafine, a squalene epoxidase inhibitor, and to fenpropimorph, a sterol Δ 14 -reductase and/or Δ 8 → Δ 7 -isomerase inhibitor, were investigated in laboratory mutants of the phytopathogenic fungus Nectria haem
