1. Antifungal compounds useful in the agricultural field having the formula:

  • ##STR7## wherein;

    R1 and R2, which may be either equal to, or different from, each other, represent H atoms, either linear or branched (C1 -C6)-alkyl groups,Ar-B groups in which Ar is a (C6, C10)-aryl or (C6, C10)-halo-aryl group andB is a (C1 -C4)-alkylene or (C1 -C2)-alkyl-(C1 -C4)-alkylene group, or R1 and R2 taken together with the N atom form a (C3 -C8)-heterocyclic group or a (C2 -C7)-heterocyclic group containing a second heteroatom selected from among O and S, said heterocyclic groups being optionally substituted with one or more C1 -C4 alkyl groups, (C6 -C10)-aryl groups, halogens, or Ar-B groups in which the symbols Ar and B have the same meanings are defined above;

    R3 represents a (C1 -C3)-alkyl group;

    R4 which, when m is greater than 1, may be either different from, or equal to, one another, represent halogen atoms, (C1 -C3)-alkyl groups or (C1 -C3)-halo-alkyl groups;

    m is an integer within the range of from 0 to 4;

    R'"'"', R", which may be either equal to, or different from, each other, represent H, (C1 -C3)-alkyl group or halogen atoms;

    n is an integer within the range of from 0 to 3;

    Y represents a ##STR8## group in which C, D, E, either equal to, or different from, one another, represent H atoms, (C1 -C4) alkyl groups, (C1 -C4)-haloalkyl groups, (C1 -C4) alkoxy groups, (C1 -C4)-halo-alkoxy groups, (C6,C10) -aryl groups, and (C6, C10)-haloaryl groups;

    their enantiomers and diastereoisomers and corresponding metal salts and complexes.
