The invention provides imidazole dioxolane derivatives of the general formula: ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents an optionally substituted phenyl group; R.sup.1 represents a hydrogen atom or an optionally substituted alkyl or alkenyl group; R.sup.2 represents an optionally substituted alkyl group; and n is 1 or 2; processes for their preparation; compositions containing such compounds and their use as fungicides.

Fungicidal imidazole dioxolane and 1,3-dioxane derivatives

The invention provides imidazole oxime derivatives of the general formula I: ##STR1## or an acid-addition salt or metal salt complex thereof, in which R represents an optionally substituted phenyl group; R.sup.1 represents an optionally substituted alkyl, alkenyl, alkynyl, or aralkyl group; and R.sup.2 represents an optionally substituted alkyl group; processes for their preparation; compositions containing such compounds and their use as fungicides.

Fungicidal imidazole oxime derivatives

The invention provides imidazole derivatives of the general formula I: ##STR1## or a salt thereof, in which R represents an optionally substituted phenyl group, R.sup.1 represents an optionally substituted alkyl, cycloalkyl, alkenyl, aryl or aralkyl group, R.sup.2 represents an optionally substituted alkynyl group and Y represents an oxygen or sulphur atom; processes for their preparation and their use as fungicides.

Imidazole derivatives, their preparation and their use as fungicides

Fungicidal compositions comprise at least one morpholine-type fungicide and at least one imidazole derivative of general formula (I): ##STR1## or a salt thereof; where R represents an optionally substituted phenyl group, R.sup.1 represents an optionally substituted alkyl, cycloalkyl, alkenyl, aryl or aralkyl group, R.sup.2 represents an optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, aryl or aralkyl group, and X represents an oxygen or sulphur atom or a group --NR.sup.3 --, where R.sup.3 represents a hydrogen atom or an optionally substituted alkyl group or R.sup.2 and R.sup.3 together with the interjacent nitrogen atom represent a 5- or 6- member saturated or unsaturated heterocyclic ring optionally containing one or two further heteroatoms. The compositions are particularly useful in combating wheat leaf spot and powdery mildews.
