These formulations are prepared in a known manner, for example by mixing the active ingredients with extenders, that is to say liquid solvents, pressurized liquefied gases and / or solid carriers, if appropriate using formation of surface-active agents, ie emulsifiers and / or dispersants and / or foam-generating agents. If water is used as an extender, organic solvents can, for example, also be used as auxiliary solvents. The following are essentially suitable as liquid solvents: aromatics, such as xylene, toluene or alkylnaphthalenes, 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 its 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 halogenated hydrocarbons and butane, propane, nitrogen and carbon dioxide. The following are suitable as solid carriers: for example, natural rock powders such as kaolins, alumina, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth and synthetic rock powders such as highly disperse silica, aluminum oxide and silicates. Possible solid carriers for granules are: eg broken and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite as well as synthetic granules from inorganic and organic flours as well as granules from organic material such as sawdust, coconut shells, corn cobs and tobacco stalks. Suitable 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 sulfate and methyl cellulose.

In the formulations, adhesives such as carboxymethyl cellulose, natural and synthetic powdery, granular or latex-shaped polymers can be used, such as gum arabic, polyvinyl alcohol, polyvinyl acetate and natural phospholi- pide, such as cephalins and lecithins, and synthetic phospholipids. Other additives can be mineral and vegetable oils.

Dyes such as inorganic pigments, e.g. 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 formulations generally contain between 0.1 and 95 percent by weight of active compound, preferably between 0.5 and 90%.

The active compounds which can be used according to the invention, as such or in their formulations, can also be used in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, in order, for example, to spread the spectrum of activity or to prevent the development of resistance. In many cases, synergistic effects are obtained, i.e. the effectiveness of the mixture is greater than the effectiveness of the individual components.
