Abstract

The invention relates to the fungicidal compositions of formula (II): ##STR1## in which: R denotes PA1 a lower alkyl radical, optionally substituted with one or more substituents chosen from halogen, and preferably chlorine, fluorine or bromine, atoms, a lower alkoxy radical and a radical --(CH.sub.2).sub.x Si R.sub.1 R.sub.2 R.sub.3, x=0 or 1 and R.sub.1, R.sub.2 and R.sub.3, which may be identical or different, being lower alkyl, lower alkoxy, aryl (in particular phenyl) or aralkyl (in particular benzyl); PA1 an alkenyl, and preferably allyl, radical, optionally substituted as when R denotes alkyl or with a C.sub.1 to C.sub.3 alkyl group; PA0 =lower haloalkoxy, preferably containing 1 to 3 carbon atoms, advantageously trifluoromethoxy, lower haloalkyl, preferably containing 1 to 3 carbon atoms, advantageously trifluoromethyl, or halogen (preferably chlorine or bromine); PA0 n=1, 2 or 3, it being possible for Y to be identical or different when n=2 or 3.
