In the preparation of an ω-azolyl-acetophenone oxime ether of the formula STR1 in which R is halogen, alkyl, alkoxy, alkylthio, alkylsulphonyl, halogenoalkyl, nitro, cyano, optionally substituted phenyl or optionally substituted phenoxy, R' is alkyl, alkenyl, alkynyl, optionally substituted cycloalkylalkyl, optionally substituted aralkyl or optionally substituted aralkenyl, n is 1, 2 or 3, Hal is halogen, and Z is CH or N, wherein the ω-halogen of an ω-halogeno-acetophenone of the formula STR2 is replaced by an azole of the formula STR3 and the keto oxygen is replaced by the improvement which comprises first reacting the ω-halogeno-acetophenone with a hydroxylamine ether of the formula to produce an ω-halogeno-acetophenone oxime ether of the formula STR4 and reacting the acetophenone oxime ether with the azole, thereby to obtain the desired product in enhanced yield. The intermediate acetophenone oxime ethers are new.

A method of combating Botrytis fungi, comprising applying to such fungi, or to a habitat thereof to be protected against such fungus a fungicidally effective amount of a 1-(2,4-dichlorophenyl)-1-(2,6-dihalogenobenzyloximino)-2-(1,2,4-triazol-1-yl)-ethane of the formula STR1 in which X and Y each independently is halogen or a physiologically acceptable acid addition salt thereof. Those compounds in which X is chlorine or fluorine and Y is fluorine are new.
