temperature and are distinguished by valuable microbicidal properties They can be used in the agricultural sector or related fields preventively and curatively in the control of plant-destructive microorganisms The compounds of formula I according to the invention are distinguished at low rates of concentration not only by outstanding microbicidal, especially fungicidal, activity but also by being especially well tolerated by plants Surprismgly, it has now been found that the compounds of formula I have for practical purposes a very advantageous biocidal spectrum in the control of phytopathogenic microorganisms, especially fungi They possess very advantageous curative and preventive properties and are used in the protection of numerous crop plants With the compounds of formula I it is possible to inhibit or destroy phytopathogenic microorganisms that occur on various crops of useful plants or on parts of such plants (fruit, blossom, leaves, stems, tubers, roots), while parts of the plants which grow later also remain protected, for example, against phytopathogenic fungi The novel compounds of formula I prove to be effective against specific genera of the fungus class Fungi imperfecti (e g Cercospora), Basidiomycetes (e g Puccinia) and Ascomycetes (e g Erysiphe and Ventuπa) and especially against Oomycetes (e g Plasmopara, Peronospora, Pythium and Phytophthora) They therefore represent in plant protection a valuable addition to the compositions for controlling phytopathogenic fungi The compounds of formula I can also be used as dressings for protecting seed (fruit, tubers, grains) and plant cuttings from fungal infections and against phytopathogenic fungi that occur in the soil The invention relates also to compositions comprising compounds of formula I as active ingredient, especially plant-protecting compositions, and to the use thereof in the agricultural sector or related fields In addition, the present invention includes the preparation of those compositions, wherein the active ingredient is homogeneously mixed with one or more of the substances or groups of substances described herein Also included is a method of treating plants which is distinguished by the application of the novel compounds of formula I or of the novel compositions Target crops to be protected within the scope of this invention comprise, for example, the following species of plants cereals (wheat, barley, rye, oats, rice, maize, sorghum and related species), beet (sugar beet and fodder beet), pomes, stone fruit and soft fruit (apples,

simultaneously or in succession with other active ingredients Those other active ingredients may be fertilisers, micronutnent donors or other preparations that influence plant growth It is also possible to use selective herbicides or insecticides, fungicides, bacteπcides, nematicides, molluscicides or mixtures of several of those preparations, if desired together with further carriers, surfactants or other application- promoting adjuvants customarily employed in formulation technology The compounds of formula I can be mixed with other active ingredients, for example fertilisers,
