New microbicidal, optionally solvent- and emulsifier-free microbicidal active compound combinations and agents comprising known azole fungicides and quaternary ammonium compounds and their use in the preservation of materials.

Water-based, solvent- and emulsifier-free microbicidal active compound combination

Water-based, solvent- and emulsifier-free microbicidal active compound

1-Thiocarbamoyl-5-hydroxy-pyrazoles have a microbicidal action and are therefore suitable for use for the preservation of materials. Since, in contrast to other microbicides, they are ecologically acceptable and do not discolour plastics, paints and paint films, they are particularly recommended for use in these substances.

1-thiocarbamoyl-5-hydroxy-pyrazoles as microbicides

New synergistic microbicidal active compound combinations, and the use thereof, comprising an azole fungicide, such as hexaconazole, and an iodopropargyl derivative, such as IPBC, if appropriate with the addition of other active compounds.

Microbicidal active compound combinations

New cyanoalkene derivatives of the formula (I) ##STR1## are described, in which R and R.sup.1 have the meaning given in the description, and a process for their preparation. The new cyanoalkene derivatives are used for combating microorganisms for the protection of industrial materials.

Cyanoalkene derivatives, process for their preparation, and their use as

There were described microbicidal agents for the protection of aqueous functional fluids which contain, as active substances, a combination of at least one iodopropargyl derivative and benzyl alcohol mono(poly)hemiformal.

Microbicidal agents

Microbicidal synergistic combinations of active compounds composed of known azol and benzimidazole derivatives are described, as is their use in the protection of materials.

Microbicidal combinations of active compounds

The invention relates to the use of certain 1-[2-pyri(mi)dyl]-5-hydroxy-pyrazoles which are characterized by formula (I) given in the description, as microbicides for the protection of industrial materials, and to certain novel 1-[2-pyri(mi)dyl]-5-hydroxy-pyrazoles which are characterised by formula (II) given in the description.

1-[pyri(mi)dyl-(2)]-5-hydroxy-pyrazole microbicides

New compounds of the formula (I) ##STR1## in which R.sup.1 -R.sup.6 have the meanings given in the description, their preparation and use in plant protection, the protection of materials and in the field of human and veterinary medicine. Formula (I) gives a definition of the compounds which can be prepared by analogous processes, for example from suitable benzothiophene derivatives by oxidation.

Benzothiophene-2-carboxamide S,S-dioxides and use

New synergistic microbicidal active compound combinations, and the use thereof, comprising an azole fungicide, such as tebuconazole, and an iodopropargyl derivative, such as IPBC, if appropriate with the addition of other active compounds.

The invention relates to the use of certain 1-[2-pyri(mi)dyl]-5-hydroxy-pyrazoles which are characterized by formula (I) given in the description, as microbicides for the protection of industrial materials, and to certain novel 1-[2-pyri(mi)dyl]-5-hydroxy-pyrazoles which are characterized by formula (II) given in the description.
