  • Patent number: 5250557
    Abstract: The combination of the plant microbicide 4-(2,2-difluoro-1,3-benzodioxol-7-yl)-1H-pyrrole-3-carbonitrile with the plant microbicide 1-{2-[2-chloro-4-(4-chlorophenoxy)phenyl]-4-methyl-1,3-dioxolan-2-ylmethyl }-1H-1,2,4-triazole results in a synergistically increased effect in the control of plant diseases. Microbicidal compositions based on such combinations are suitable for treating crops of plants and natural products of vegetable and animal origin, and for seed treatment.
    Type: Grant
    Filed: November 15, 1991
    Date of Patent: October 5, 1993
    Assignee: Ciba-Geigy Corporation

  • Patent number: 5250556
    Abstract: The combination of the plant microbicide 4-(2,2-difluoro-1,3-benzodioxol-7-yl)-1H-pyrrole-3-carbonitril with the plant microbicide .alpha.-[2-(4-chlorophenyl)ethyl]-.alpha.-(1,1-dimethyl-ethyl)-.beta.-(1H- 1,2,4-triazolyl)-1-ethanol results in a synergistically enhanced effect in the control of plant diseases. Microbicidal compositions based on such combinations are suitable for treating natural products of vegetable and animal origin and, in particular, for seed treatment.
    Type: Grant

  • Patent number: 4940720
    Abstract: The combination of the plant microbicide 3-cyano-4-(2,3-dichlorophenyl)-pyrrole ("fenpiclonil") with the plant microbicide 1-(1H-1,2,4-triazol-1-yl)-2-methoxy-2-[4-(4-chlorophenoxy)-2-chlorophenyl] -butane results in a synergistically enhanced activity in the control of plant diseases. Plant microbicidal compositions based on such combinations are especially suitable for treating seed.
    Type: Grant
    Filed: August 2, 1989
    Date of Patent: July 10, 1990
    Assignee: Ciba-Geigy Corporation
