CA 1068283

ABSTRACT OF THE DISCLOSURE The invention relates to novel heterocyclic compounds of the formula: Image wherein R represents a hydrogen atom; an alkyl group with 1 to 12 carbon atoms which may, if desired, be substituted by 1 or 2 halogen atoms, phenoxy groups, alkyl or halogen-substituted phenoxy groups or phenyl groups optionally sub- stituted by a halogen atom or an alkyl or alkoxy group; an alkenyl group or an alkenyl group substituted by a phenyl group; a phenyl group optionally sub- stituted by a halogen atom, an alkyl, alkoxy or nitro group; or an alkoxy, furyl or cycloalkyl group and Y represents a nitrogen atom or the group =CH-, with the proviso that if Y represents the group =CH- then R is not a furyl group. The invention also relates to processes for the preparation of these compounds. The heterocyclic compounds possess interesting activity against fungi, in particular, against genuine mildew such as erysiphe graminis and erysiphe cichoracearum. Processes for the production of the novel compounds are exemplified and compositions containing the novel compounds are described and exemplified.
