Abstract excerpt

BACKGROUND: 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, naturally resistant. Fenhexamid was suggested to inhibit the 3-ketoreductase involved at C-4 demethylation steps during ergosterol biosynthesis, as revealed...
