    [87] Indeed, in order to control phytopathogenic diseases of crops, one method involves, for example, applying an effective amount of the composition according to the invention to plants or the medium in which they are grown. In the case of the method, the active ingredient is usually applied to the site where it is necessary to control the rampant in an effective amount of about 0.05 to about 500 g of active ingredient per hectare of area to be treated. Under ideal conditions, depending on the nature of the phytopathogenic fungi to be treated, small dosages may provide suitable protection. In contrast, insufficient climatic conditions, resistance or other factors may require a large dose of active ingredient.
    [88] The effective workload of the combinations used in the present invention may vary in various proportions, in particular depending on the nature of the phytopathogenic fungi to be removed or, for example, the prevalence of these fungi in plants.
    [89] Optimal dosages typically depend on several factors, such as the type of phytopathogenic fungi to be treated, the type or extent of development of the prevailing plant, the density of the plant, or alternatively the method of application.
