They thus possess fungicidal properties against phytophathogenic fungi on various cultivated plants, such as cereals, maize, rice, vegetables, ornamental plants, fruit trees, vines, farms products, etc.

With the new active substances it is possible to con trol or destroy fungi occurring onfruit, blossom, leaves,

stems, tubers and roots, and from which parts of plants which grow later then also remain free. The active sub stances of theformula I are active in particular against phytopahtogenic fungi belonging to the following classes: Oomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, Denteromycetes.

In addition, the new active substance can also be used for treating seeds, fruits, tubers etc., and the protecting them from fungus infections, for example from smut fungi of all kinds, such as Ustilaginales, e.g. Ustilago, Tilletia, Urocystis, Turbicinia and Phoma types.

In addition to the above cited acaricides and insecti-- cides, it is also possible to admix' the active substances of the formula I with, for example, batericides, fungi- I static agents, baceteriostatic agents, nematocides andthe activity spectrum: dodecylquanidine acetate (DODlNE) (CHLOR- N'-dichlorofluoromethylthio-N,N-dimethyl-N'- phenylsulfamide (DICHLOFLUANID) O-ethyl-S-benzyl-phenyldithiophosphate 0,0-diethyl-S-benzyl-thiolphosphate disodium-ethylene-1,2-bis-dithiocarbamate (NABAM) zinc-ethylenel ,2-bis-dithiocarbamate (ZINEB) manganese-ethylene-l ,2-bis-dithiocarbamate meric) (MANEB) tetramethyliuramdisulfide (THIRAM) l -oxy-3-acetyl-6-methyl-cyclohexene-( 5 )dione-( 2,4) (DEHYDROACETIC ACID) 8-hydroxyquinoline (8-QUINOLINOL) 3O 2-dimethylamino-6-methyl 5-n-butyl-4-hydroxyprimidine methyl-N-benzimidazole-2yl-N-(butylcarbamoyl)carbamate (BENOMYL) 2-ethylamino-6-methyl-5n-butyl-4-hydroxypyrimidine 2,3-dicyano-1,4-dithia-anthraquinone (DITHIANON 2-(4-thiazolyl)-benzimidazole 3 ,S-dimethyltetrahydro-l ,3 ,5'-thiadiazine-2-thione (DAZOMET) 2,3-dihydro-5-carboxanilido-6-inethyll ,4-oxathine 40 pentachlorobenzyl alcohol.-

Furthermore, the compounds of the formula I are suitable for combating plant pathogenic nematodes.

The compounds of the formula I may be used as pure active substance 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 technology. Mention may also be made of cattle clips and spray races," in which aqueous preparations are used.

The agents according'to the invention are manufactured in known manner by intimately mixing and/or 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 take and be used in the following forms:

Solid forms:

Dusts, tracking agents, granules, coated granules, impregnated granules and homogeneous granules.

Liquid forms:

a. active substances which are dispersible in water:

wettable powders, pasts, 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, bo- Ius, 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, S10 granicalci um, bentonite etc. and then evaporatingthe solvent. v

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 the 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 a dispersibility (dispersing agents). Examples of suitable adhesives are the following: olein/chalk mixture, cellulose derivates (methyl cellulose, carboxy methyl cellulose), hydroxyethyl glycol ethers of monoalkyl and dialkyl phenols having 5 to 15 ethylene oxide radicals per molecule and 8 to 9 carbon atoms in the alkyl radical, lignin sulphonic 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 moi ety, 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 substanceand anti-foam agents and, optionally, solvents.

W'ettable powders and pastes are obtained by mixing and grinding the active substances with dispersing agents and pulverulentcarriers in suitable apparatusuntil homogeneity is attained. Suitable 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, a]-

kylaryl sulfonates, alkali and alkaline-earth metal salts of dibutyl naphthalene sulfonic acid, fatty alcohol sulfates such as salts 'of sulfated hexadecanols, hep- 'tadecanols, octadecanols, and salts of sulfated fatty alcohol glycol ethers, the sodium salt of oleoyl ethionate, the sodium salt of oleoyl methyl tauride, ditertiary acetylene glycols, dialkyl fatty acid alkali and alkaline earth metal salts.

Suitable anti-foam agents are silicones. g

The active substances are mixed, ground, sieved and strained with the additives cited hereinabove in such a. manner that, in wettable powders, the solid particle size of from 0.02 to 0.04 and in pastes, of 0.03 is notexdilauryl ammonium chloride and ceeded. To produce emulsifiable concentrates and pastes, dispersing agents such as those cited above,-organic solvents and water are used. Examples of suitable solvents are: alcohols, benzene, xylene, toluene dimethyl sulfoxide, and mineral oil fractions boiling between 120 and 350C. 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 purpose the active substance or several active substances of the general formula I are dissolved in suitableorganic solvents, mixtures of solvents or in water. Aliphatic and aromatic hydrocarbons, chlorinated derivatives thereof, alkyl naphthalenes, and mineral oils singly or in admixture 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 percent, 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 99.5 percent or even pure active substance.

The active substances of the formula I can, for example, be formulated as follows: Dusts The following substances are used to manufacture (a) a 5 percent and (b) a 2 percent dust: v

a. 5 parts of active substance 95 parts of talcum b. 2 parts of active substance 1 part of highly disperse silica 97 parts of talcum. The active substances are mixed with the carriers and ground. Granules The following substances are used to produce 5% granules:
