They are used in the usual way, e.g. by pouring, spraying, spraying, scattering, dusting, foaming, brushing, etc. It is also possible to apply the active ingredients by the ultra-low-volume method or to inject the active ingredient preparation or the active ingredient into the soil itself . The seeds of the plants can also be treated.

When treating parts of plants, the active compound concentrations in the use forms can be varied within a substantial range: they are generally between 1 and 0.0001% by weight, preferably between 0.5 and

0.001% by weight.

In the seed treatment, amounts of active ingredient of 0.001 to 50 g per kilogram of seed, preferably 0.01 to 10 g, are generally required.

When treating the soil, active substance concentrations of 0.00001 to 0.1% by weight, preferably 0.0001 to 0.02% by weight, are required at the site of action. The agents used to protect industrial materials generally contain the active ingredients in an amount of 1 to 95%, preferably 10 to 75%.

The application concentrations of the active compounds according to the invention depend on the type and the occurrence of the microorganisms to be controlled and on the composition of the material to be protected. The optimal amount of use can be determined by test series. In general, the application concentrations are in the range from 0.001 to 5% by weight, preferably from 0.05 to 1.0% by weight, based on the material to be protected.

The effectiveness and the spectrum of activity of the active substances to be used according to the invention in the protection of materials or of the agents, concentrates or very generally formulations which can be produced therefrom can be increased if further antimicrobial compounds, fungicides, bactericides, herbicides, insecticides or others are used Active ingredients to enlarge the spectrum of effects or to achieve special effects such as the additional protection from

Insects can be added. These mixtures can have a broader spectrum of activity than the compounds according to the invention.

The preparation and use of the substances according to the invention can be seen from the following examples.

Manufacturing examples

example 1

A mixture of 1.68 g (5 mmol) of 4- (4-chlorophenyl) -2-cyano-2-phenyl-l - (1,2,4-tπazol-l-yl) butane, 0.32 g (10 mmol) sulfur powder and 10 ml absolute N-

Methylpyrrolidone is heated to 200 ° C. under a nitrogen atmosphere and with stirring for 47 hours. The reaction mixture is then reduced

Concentrated pressure, and the remaining residue is dissolved in ethyl acetate. The resulting mixture is shaken several times with saturated, aqueous ammonium chloride solution. The organic phase is over

Dried sodium sulfate and then concentrated under reduced pressure. The resulting crude product (1.9 g) is purified by chromatography on silica gel with a mixture of petroleum ether and ethyl acetate = 1 l as eluent. 0.7 g (38% of theory) is obtained in this way an 4- (4-chlorophenyl) -2-cyano-2-phenyl-l- (5-mercapto-l, 2,4-triazol-l-yl) butane in the form of a

Example A

PodosphaeraTest (apple) / protective

Solvent: 4.7 parts by weight of acetone

Emulsifier: 0.3 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier and the concentrate is diluted with water to the desired concentration.

To test for protective efficacy, young plants are sprayed with the preparation of active compound as moist as dew. After the spray coating has dried on, the plants are dusted with conidia of the apple mildew pathogen

(Podosphaera leucotricha) inoculated.

The plants are then placed in a greenhouse at 23 ° C. and a relative atmospheric humidity of approx. 70%.

Evaluation is carried out 10 days after the inoculation. 0% means an efficiency which corresponds to that of the untreated control, while an efficiency of 100% means that no infection is observed.

Active substances, active substance concentrations and test results are shown in the following table.
