Claims (10)

1. A fungicidal composition comprising: a fungicidally effective amount of a mixture (a) of at least one compound selected from 5-methyl-5- (4-phenoxyphenyl) -3-phenylamino-2,4-oxazolidinone and its agriculturally acceptable salts , and (b) at least one compound selected from cymoxanil and its agriculturally acceptable salts, where the mass ratio of component (a) to component (b) is from 17: 1 to 1: 100.  2. The fungicidal composition according to claim 1, further comprising at least one of a surfactant, a solid diluent or a liquid diluent.  3. The fungicidal composition according to claim 2, where the mass ratio of component (a) to component (b) is from 8: 1 to 1:25.  4. The fungicidal composition according to claim 3, where the mass ratio of component (a) to component (b) is from 4: 1 to 1:10.  5. The fungicidal composition according to claim 4, where the mass ratio of component (a) to component (b) is from 3: 2 to 1: 3. 6. A method of suppressing plant diseases caused by fungal plant pathogens, comprising: applying to a plant or part thereof to be protected, or to plant seeds or seedlings to be protected, an effective amount of a fungicidal composition containing (a) compound Formula I

or its agriculturally acceptable salt, (b) cymoxanil or its agriculturally acceptable salt, and (c) at least one of a surfactant, solid diluent or liquid diluent; moreover, the mass ratio of the applied compound (a) and compound (b) is from 17: 1 to 1: 100, and the compound (a) and compound (b) is applied in amounts effective to ensure the suppression of the fungal disease, which manifests itself more significantly than the total suppression of fungal disease when using compound (a) and compound (b) separately.  7. The method according to claim 6, where the fungal pathogen of the plant is Phytophthora infestans.  8. The method of claim 6, wherein the plant fungal pathogen is Plasmopara viticola. 9. A method of suppressing plant diseases caused by fungal pathogens of plants, comprising: applying successively in any order to the plant or to its part, which must be protected, or to the seeds of the plant or seedling, which must be protected, (i) an effective amount of the first compositions containing (a) a compound of formula I

or its agriculturally acceptable salt, and (c1), at least one of a surfactant, solid or liquid diluent; and (ii) an effective amount of a second composition comprising (b) cymoxanil or an agriculturally acceptable salt thereof, and (c2) at least one of a surfactant, solid diluent or liquid diluent; moreover, the mass ratio of the applied compound (a) and compound (b) is from 17: 1 to 1: 100, and the compound (a) and compound (b) is applied in amounts effective to ensure the suppression of the fungal disease, which manifests itself more significantly than the total suppression of fungal disease when using compound (a) and compound (b) separately. 10. A method of suppressing plant diseases caused by fungal plant pathogens, comprising: applying an effective amount of a physical mixture (i) of the first composition to a plant or part thereof, which must be protected, or a plant seed or seedling that must be protected; containing (a) a compound of formula I

or its agriculturally acceptable salt, and (c1), at least one of a surfactant, solid or liquid diluent; and (ii) an effective amount of a second composition comprising (b) cymoxanil or an agriculturally acceptable salt thereof, and (c2) at least one of a surfactant, solid diluent or liquid diluent; moreover, the mass ratio of the applied compound (a) and compound (b) is from 17: 1 to 1: 100, and the compound (a) and compound (b) is applied in amounts effective to ensure the suppression of the fungal disease, which manifests itself more significantly than the total suppression of fungal disease when using compound (a) and compound (b) separately.
