- Plants are understood here to mean all plants and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants).
- Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant cultivars which can or cannot be protected by plant breeders' rights.
- Plant parts are to be understood to mean all above-ground and underground parts and organs of the plants, such as shoots, leaves, flowers and roots, examples being leaves, needles, stems, stems, flowers, fruiting bodies, fruits and seeds as well as roots, tubers and rhizomes.
- the plant parts also include crops and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offshoots and seeds.
- the treatment of the plants and parts of plants with the active compounds according to the invention is carried out directly or by acting on their surroundings, living space or storage space using the customary treatment methods, e.g. by dipping, spraying, vaporizing, atomizing, scattering, spreading and, in the case of propagation material, in particular in the case of seeds, furthermore by coating in one or more layers.
- the active ingredient combination according to the invention can be converted into the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, very fine encapsulations in polymeric substances and in coating compositions for seeds, and ULV formulations.
- These formulations are prepared in a known manner, for example by mixing the active ingredients or combinations of active ingredients with extenders, that is to say liquid solvents, • pressurized liquefied gases and / or solid carriers, if appropriate using surface-active agents, that is to say emulsifiers and / or dispersants and / or foam-generating agents.
- extenders that is to say liquid solvents, • pressurized liquefied gases and / or solid carriers, if appropriate using surface-active agents, that is to say emulsifiers and / or dispersants and / or foam-generating agents.
- organic solvents can, for example, also be used as auxiliary solvents.
- aromatics such as xylene, toluene or alkylnaphthalamine
- chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chlorethylenes or methylene chloride
- aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions
- alcohols such as butanol or glycol and their ethers and esters
- ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone
- strongly polar solvents such as dimethylformamide and dimethyl sulfoxide, and water.
- Liquefied gaseous extenders or carriers mean liquids which are gaseous at normal temperature and under normal pressure, for example aerosol propellants such as butane, propane, nitrogen and carbon dioxide.
- Solid carrier materials are suitable: for example natural rock powders, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth and synthetic rock powders, such as highly disperse silica, aluminum oxide and silicates. The following are suitable solid carriers for granules: e.g.
- Possible emulsifiers and / or foam-generating agents are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulfonates, alkyl sulfates, aryl sulfonates and protein hydrolyzates.
- Possible dispersing agents are, for example, lignin sulfite waste liquor and methyl cellulose.
- Adhesives such as carboxymethyl cellulose, natural and synthetic polymers in the form of powders, granules or latices, such as rubber arabic, polyvinyl alcohol, polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids can be used in the formulations.
- Other additives can be mineral and vegetable oils.
- Dyes such as inorganic pigments such as iron oxide, titanium oxide, ferrocyan blue and organic dyes such as alizarin, azo and metal phthalocyanine dyes and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc can be used.

- the good fungicidal activity of the active compound combination according to the invention can be seen from the examples below. While the individual active ingredients have weaknesses in their fungicidal action, the combinations of three active ingredients show an action that goes beyond a simple longitudinal curvature.
- Fungicides always have a synergistic effect if the fungicidal activity of the active ingredient combination is greater than the sum of the effects of the individually applied active ingredients.
- the expected effect for a given combination of 2 or 3 active substances can be calculated according to SR Colby ("Calculating Synergistic and Antagonistic Responses of Herbicide Combinations", Weeds 1967, 15, 20-22) as follows:
- X means the efficiency when using the active ingredient A in an application rate of m g / ha
- Y means the efficiency when using the active ingredient B in an application rate of n g / ha
- Z means the efficiency when using the active ingredient C in an application rate of r_g / ha
- E ⁇ means the efficiency when using active ingredients A and B in application rates of m and n g / ha and
- E2 means the efficiency when using the active ingredients A and B and C in application rates of m and n and r g / ha,
- the efficiency is determined in%. It means 0% an efficiency that corresponds to that of the control, while an efficiency of 100% means that no infection is observed.
- the combination of the combination is superadditive, ie there is a synergistic effect.
- the actually observed efficiency must be greater than the value for the expected efficiency ⁇ or E2 calculated from the above formula.
- Solvent 10 parts by weight of N-methyl-pyrrolidone emulsifier: 0.6 part by weight of alkylaryl polyglycol ether
