Especially they possess fun- 10 gicidal properties against phytopathogenic fungi of the following classes: Oomyetes, Phycomycetes, Ascomycetes, Basidiomycetes, Denteromycetes.  
  Because of their biocidal properties, the compounds of formula I can be used not only in plant protection but also for disinfecting and protecting various types of material from fungal attack. In this connection, it has proved particularly advantageous that the compounds of formula I generate no poisonous effects in warmblooded animals in the concentrations necessary for disinfection and materials protection.  
  The compounds of formula I can be formulated in various mixing ratios with known fungicides and microbicides, whereby mixtures of compounds arise with advantages compared to the individual components. The following known fungicides are, for example, suitable for formulating with the active substances of formula I:  
 dodecylguanidine acetate (DODINE) pentachloronitrobenzene (QUINTOZENE) pentachlorophenol (PCP) 2-( l-methyl-n-propyl )-4,6-dinitrophenyl-Z-methylcrotonate (BINAPACRYL) 2-( l-methyl-n-heptyl )-4,6-dinitrophenylcrotonate (DINOCAP) 2,6-dichIoro-4-nitroaniline (DICHLORAN) 2,3,5,6-tetrachloro-benzoquinone (1,4) (CHLOR- ANIL) 2,3-dichloro-naphthoquinone (1,4) (DICHLONE) N-(trichloromethylthio) phthalimide (FOLPAT) N-(trichloromethylthio) cyclohex-4-enl ,2-

 chulus sp., Tylenchulus semipenetrans, Radopholus similus, Belonolaimus sp., Trichodorus sp., Longidorus sp., Aphelenchoides sp., Xiphinema sp.  
  The compounds of the formula I may be used as pure active substances or together with suitable carriers and- /or additives. Suitable carriers and additives can be solid or liquid and correspond to the substances conventionally used in formulation technique such, for example, as solvents dispersants, wetting agents, adhesives, thickeners, binders and/or fertilisers.  
  For application, the compounds of the formula I may be processed to dusts, emulsion concentrates, granules, dispersions, sprays, to solutions, or suspensions in the conventional formulation which is commonly employed in application terminology. Mention may also be made of cattle dips and spray races&#34;, in which aqueous preparations are used.  
  The agents according to the invention are manufactured in known manner by intimately mixing and/r grinding active substances of the formula I with the suitable carriers, optionally with the addition of dispersants or solvents which are inert towards the active substances. The active substances may be available and can be used in the following forms:  
 Solid forms Dusts, tracking agents, granules, coated granules, impregnated granules and homogeneous granules. Liquid forms:  
 a. active substance concentrates dispersible in water:  
 wettable powders, pastes, emulsions;  
 b. solutions.  
  To manufacture solid forms (dusts, tracking agents), ,the active substances are mixed with solid carriers. Suitable carriers are, for example: kaolin, talcum, bolus, loess, chalk, limestone, ground limestone, attaclay, dolomite, diatomaceous earth, precipitated silica, alkaline earth silicates, sodium and potassium aluminium silicates (feldspar and mica), calcium and magnesium sulphates, magnesium oxide, ground synthetic materials, fertilisers, for example ammonium sulphate, ammonium phosphate, ammonium nitrate, urea, ground vegetable products, such as corn meal, bark dust, sawdust, nutshell meal, cellulose powder, residues of plant extractions, activated charcoal etc. These substances can either be used alone or in admixture with one another.  
  Granules can be very easily manufactured by dissolving an active substance of the formula I in an organic solvent and applying the resulting solution to a granulated material, for example attapulgite, SiO granicalcium, bentonite etc. and then evaporating the solvent.  
  Polymer granules can also be manufactured by mixing the active substances of the formula I with polymerisable compounds (urea/formaldehyde; dicyandiamide/formaldehyde; melamine/formaldehyde or others), whereupon a mild polymerisation is carried out that does not affect the active substances and in the process of which the granulation is carried out during thhe gel formation. It is more advantageous to impregnate finished, porous polymer granules (urea/formaldehyde, polyacrylonitrile, polyester or others) which have a specific surface area and a favourable predeterminable adsorption/desorption ratio, with the active substances, for example in the form of their solutions (in a low boiling solvent) and to remove the solvent. Polymer granules of this kind in the form of microgranules having a bulk density of 300 g/litre to 600 g/litre can also be manufactured with the aid of atomisers. The dusting can be carried out from aircraft over extensive areas of cultures of useful plants.  
  It is also possible to obtain granules by compacting the carrier with the active substance and carriers and subsequently comminuting the product.  
  To these mixtures can also be added additives which stabilize the active substance and/or non-ionic, anionic and cationic surface active substances, which for example improve the adhesion of the active ingredients on plants or parts of plants (adhesives and agglutinants) and/or ensure a better wettability (wetting agents) and dispersibility (dispersing agents). Examples of suitable adhesives are the following: olein/chalk mixture, cellulose derivatives (methyl cellulose, carboxymethyl cellulose), hydroxyethyl glycol ethers of monoalkyl and dialkyl phenols having 5 to 15 ethylene oxide radicals per moecule and 8 to 9 carbon atoms in the alkyl radical, lignin sulfonic acids, their alkali metal and alkaline earth metal salts, polyethylene glycol ethers (carbowaxes), fatty alcohol polyethylene glycol ethers having 5 to 20 ethylene oxide radicals per molecule and 8 to 18 carbon atoms in the fatty alcohol moiety, condensation products of ethylene oxide/propylene oxide, polyvinyl pyrrolidones, polyvinyl alcohols, condensation products of urea and formaldehyde, and also latex products.  
  The water-dispersible concentrates of the active substance, i.e., wettable powders, pastes and emulsifiable concentrates, are agents which can be diluted with water to any concentration desired. They consist of active substance, carrier. optionally additives which stabilize the active substance, surface-active substance and anti-foam agents and, optionally, solvents.  
  Wettable powders and pastes are obtained by mixing and grinding the active substances with dispersing agents and pulverulent carriers in suitable apparatus until homogeneity is attained. Carriers are, for example, those mentioned for the solid forms of application. In some cases it is advantageous to use mixtures of different carriers. As dispersing agents there can be used, for example, condensation products of sulfonated naphthalene and sulfonated naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalene sulfonic acids with phenol and formaldehyde, as well as alkali, ammonium and alkaline earth metal salts of lignin sulfonic acid, in addition, alkylaryl sulfonates, alkali and alkaline earth metal salts of dibutyl naphthalene acid, fatty alcohol sulfates such as salts of sulfated hexadecanols, heptadecanols, octadecanols, and salts of sulfated fatty alcohol glycol ethers, the sodium salt of oleyl methyl tauride, ditertiary ethylene glycols, dialkyl dilauryl ammonium chloride and fatty acid alkali and alkaline earth metal salts.  
 Suitable anti-foam agents are silicone oils.  
  The active substances are mixed, ground, sieved and strained with the additives mentioned above that, in wettable powder, the solid particle size of from 0.02 to 0.04 and in pasts, of 0.03 mm is not exceeded. To produce emulsifiable concentrates and pastes, dispersing agents such as those cited above, organic solvents and water are used. Examples of suitable solvents are the following: alcohols, benzene, xylenes, toluene, dimethyl sulfoxide, and mineral oil fractions boiling between and 350 C. The solvents must be practically odourless not phytotoxic, inert to the active substances.  
  Furthermore, the agents according to the invention can be applied in the form of solutions. For this pur pose the active substance or several active substances of the general formula 1 are dissolved in suitable organic solvents, mixtures of solvents or in water. Aliphatic and aromatic hydrocarbons, chlorinated derivatives thereof, alkyl naphthalenes, and mineral oils alone or mixed with each other, can be used as organic solvents.  
  The content of active substance in the above described agents is between 0.1 to 95%, in which connection it should be mentioned that in the case of application from aircraft or some other suitable means of application. it is possible to use concentrations of up to 99.57: or even pure active substance.  
  The active substances of the formula I can, for example, be formulated as follows:
