ABSTRACT:
##STR1## in which: CYCLE surrounded by a semicircle represents, with the two carbon atoms to which the semicircle is linked, a carbon-containing, optionally heterocyclic, ring containing at least one ethylenic or aromatic bond between the two carbon atoms which carry the --C(Z).dbd.Y group and the phenyl group, Y is oxygen or sulphur, Z is NR.sub.1 R.sub.2, R.sub.1 and R.sub.2, each represents optionally substituted alkyl, alkoxy or cycloalkyl; alkenyl or alkynyl; or --NR.sub.1 R.sub.2 represents saturated or unsaturated heterocyclyl;
R.sub.3, R.sub.4 and R.sub.5, each represents a hydrogen or halogen atom (at least one of R.sub.3, R.sub.4 and R.sub.5 being other than hydrogen or halogen); optionally substituted amino; optionally halogenated or hydroxylated alkyl, alkoxy, alkylalkoxy or alkylthio; or R.sub.3 and R.sub.4 (in the 3- and 4-positions) can together form a single divalent radical with 3 or 4 members containing 1 or 2 non-adjacent oxygen atoms; are useful as agricultural fungicides.
