摘要

The novel compounds, which exhibit activity as bactericides and fungicides, are compounds of Formula I below, or salts or metal salt complexes thereof,
<CHEM>
wherein R<1> is (C1-C8) alkyl, (C3-C6) cycloalkyl, phenyl-(C1-C4) alkyl or phenyl optionally substituted with up to 3 of the same or different halogen atoms;
R<2> is hydrogen, halogen or (C1-C4) alkyl; and R<3> is cyano, a group of the formula @@- or a
group of the formula
<CHEM>
in which Z is (-CH2-)n, n being an integer of 4 to 6 and R<4> and R<5>, which may be the same or different, is each selected from (C1-C8) alkyl and phenyl (C1-C4) alkyl or R<4> and R<5> are joined to form, together with the nitrogen atom to which they are attached, a group of the formula @@- in which Z is as defined above.
