The invention relates to substituted phenylnitramines and derivatives with fungicidal properties, and to the use of these compounds for the control of fungi, for example for the protection of living plants from attack thereby. The fungicidal phenylnitramines of this invention are compounds selected from formulae (I) and (III):
wherein the formula (I) R to R, each represent a hydrogen, halogen, C1-C4 alkyl, halo(C1-C4)alkyl, C1-C4 alkylthio, C1-C4 alkylsulfonyl, C1-C4 alkanoylamino, C1-C4 alkyl-O-C-NH-, cyano or nitrol; Y is hydrogen, C1-C8 alkyl, C3-C8 alkenyl, C3-C5 alkynyl, R6-O-R4
alkenyl or C2-C5 alkynyl; R, is C1-C4 alkylene; R, is C2-C4 alkylene; W and W' each are hydrogen or halogen; Z is hydroxy or halogen; with the provisos, that at least two of the R groups R1 to R, are other than hydrogen; and that not more than two of the R groups R, to R, are C1-C4 alkylthio, C1-C4 alkylsulfonyl or nitro; and wherein the formula (lll) cation X represents H3NR, H2NR'R", HNR'R"R"', or NR'R"R"'R"", wherein R'to R"" each represent C C1C18alkyl, aryl or benzyl, or R' and R" taken together with the nitrogen to which they are attached form the cyclic moiety:
