Abstract

Compounds of formula I are suitable for controlling and preventing infestation by microorganisms, insects and acarina on plants ##STR1## and their possible isomers and mixtures of isomers, wherein PA1 a) X is CH.sub.2 F or CHF.sub.2, PA1 Y is CH and PA1 Z is OCH.sub.3, or PA1 b) X is CH.sub.2 F or CHF.sub.2, PA1 Y is a nitrogen atom and PA1 Z is OCH.sub.3 or NHCH.sub.3, PA0 and wherein R.sub.1 and R.sub.2 are each independently of the other hydrogen, cyano, C.sub.1 -C.sub.12 alkyl, halo-C.sub.1 -C.sub.12 alkyl, C.sub.2 -C.sub.12 alkenyl, C.sub.2 -C.sub.12 alkynyl, C.sub.3 -C.sub.6 cycloalkyl, cyclopropylmethyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.12 alkoxyalkyl, C.sub.1 -C.sub.4 alkoxycarbonyl, C.sub.1 -C.sub.4 alkylthio, C.sub.2 -C.sub.5 alkylthioalkyl; or an unsubstituted or mono- to tri-substituted ring having not more than 15 ring carbon atoms that may be multi-membered and that contains from 0 to 3 hetero atoms N, O or S, it being possible for that ring to be bonded via an aliphatic bridge having not more than 4 carbon atoms and/or via CO, oxygen or sulfur, as desired; or PA0 wherein R.sub.1 and R.sub.2 together with their common carbon atom form an unsubstituted or mono- …
