[Effect of imazalil (1-(2-(2,4-dichlorophenyl)-2-(2-propenyloxy) ethyl)-1H-imidazole) on biosynthesis of ergosterol in Penicillium expansum Link].
Imazalil is a new fungicide effective against Penicillium molds on fruits after harvest. This compound inhibits ergosterol biosynthesis in mycelia of Penicillium expansum. The accumulation of 24--methylenedithydrolanosterol, obtusifoliol and 14 alpha-methyl-delta 8, 24(28)-ergostadienol in treated fungi suggests that imazalil blocks sterol C--14 demethylation.
