<p>Fungicidal compositions characterised in that they contain a compound of the general formula I <IMAGE> in which R DEG is substituted phenyl or other (substituted) aromatic radicals and heteroaromatic radicals, <IMAGE> R<1> is H, Cl, Br, (substituted) alkyl; R<2> is H, Cl, Br, alkyl, (substituted) phenyl, thienyl or furanyl R<3> and R<4> are H, (substituted) alkyl, 2,2,6,6-tetramethylpiperidin-4- yl, alkenyl, alkynyl or cycloalkyl, or R<3> and R<4> together with the nitrogen atom to which they are bonded are a (substituted) 3- to 29- membered saturated heterocyclic ring (which is bridged by a (C1-C2) alkylene chain) which can also contain an O or S atom or the group NR<7>, -CH=CH-, C=O or - CH=N as a ring member, or are (substituted) 1,2,3,4-tetrahydroisoquinoline, or (substituted) 8-aza- 1,4-dioxa spiro-(4,5)decane. A large number of compounds of this group are new and are also embraced by the invention. The compounds of the formula I have a broad fungicidal activity against phytopathogenic fungi.</p> |
