The salts of compounds [I] or [IV] can be converted in a manner known per se into different salts of compounds [I] or (IV), for example, acid addition salts into different acid addition salts, e.g. by treating a salt of an inorganic acid, with iodic acid, with a suitable metal salt, such as sodium, barium or silver salt, for example, using silver acetate, in a suitable solvent, wherein an inorganic salt which formed, for example, silver chloride is insoluble and thus separates from the reaction mixture.

The invention also relates to pesticide compositions, such as emulsifiable concentrates, concentrated suspensions, directly sprayable or dilutable solutions, spreading pills, diluted emulsions, powders, granules and encapsulations in polymeric substances, all comprising at least one active ingredient according to the invention, and can be selected depending on the intended purposes and the prevailing circumstances.

In these compositions, the active ingredient is used as a pure active ingredient, for example, a solid active ingredient in a specific particle size, or preferably together with at least one conventional auxiliary used in the formulation, such as extending, for example, solid or surface active solvents or carriers, surfactants.

Examples of such solvents are: non-hydrogenated aromatic hydrocarbons or

Partially hydrogenated, preferably fractions of 8-12 carbon atoms, with a mixture of xylin, alkylated or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffin or cyclohexane, alcohols, as ethanol, propanol or butanol and ethanol with chlorine, such as propylene glycol, dipropylene glycol ether, ethylene glycol or ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones, as cyclohexanone, isophorone or diacetanol alcohol, strong polar solvents such as N-methylpyrrolid-2-one, dimethylsulfoxide or Ν, Ν-dimethylformamide, water, epoxidized or non-oxidized vegetable oils, such as epoxidized or non-epoxidized oil, coconut oil or soybean oil and silicon oil.

Such carriers that are used, for example, for dispersible powders and powders, are usually natural minerals from the soil such as calcite, talc, kaolin, montmorilonite or atapulgite. In order to improve the physical properties, it is also possible to add high-dispersed silica or high-dispersed absorbent polymers. It is possible to use adsorbent carriers of porous granules such as pumice stone, sandstone, sepiolite or bentonite, or non-absorbent carrier materials such as calcite or sand. In addition, a large number of granular materials of an inorganic or organic nature, in particular dolomite or pulverized plant residues, may be used.

Depending on the nature of the active ingredient to be formulated, the corresponding surface active compounds are non-ionic, cationic and / or anionic surfactants or mixtures of surfactants that have good emulsifying, dispersing and wetting properties. The surfactants mentioned below are the only ones that are considered in the examples; The literature describes a large number of conventional surfactants used in the field of formulation and which correspond to this invention.

Suitable surfactants are most polyglycol derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols which may have 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the aliphatic radical, hydrocarbon 32 bonate and 6 in 18 carbon atoms in the radical. alkyl of alkylphenols. Other substances are polyethylene oxide adducts with water soluble polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbon atoms in the alkyl chain and 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. Conventionally, the above compounds contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples include nonylphenol polyethoxyethanol, polyglycol ethers of castor oil, addipolypropylene / polyethylene oxide, tributylphenoxy-polyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Esters of polyoxyethylene sorbitan fatty acids, such as polyoxyethylene sorbitan trioleate, are preferred.

Cationic surfactants are mainly quaternary ammonium salts having at least one 8 to 22 carbon atoms alkyl radical as a substituent and, as other substituents, lower, free or halogenated, alkyl, benzyl or lower hydroxyalkyl radicals. Preferred salts are in the form of halides, methylsulphates or ethylsulphates. For example, stearyltrimethylammonium chloride and benzyl di (2-chloroethyl] ethylammonium bromide.

Suitable anionic surfactants can be both water soluble soaps and synthetic water soluble surface active compounds. The corresponding soaps are alkali metal salts, metalelo salts earth salts and substituted or substituted ammonium salts of fatty acids higher than 10-22 carbon atoms, such as sodium or potassium salts of oleic or stearic acid, or natural mixtures of fatty acids that can be obtained, for example, from coconut oils or vegetable oils; metaturinated fatty acids should be mentioned. However, synthetic surfactants are more commonly used, in particular fatty sulfates, fatty sulfates, benzimidazole sulfonated derivatives or alkylaryl sulfonates. Fatty sulphonates and fatty sulphates are usually in the form of alkali metal salts, alkaline earth metal salts or ammonium salts, substituted or unsubstituted and, as a rule, have an alkyl radical having 1 to 22

Carbon atoms, alkyl including semialalkyl or acyl radicals; Examples may be mentioned, such as the sodium salt or the potassium salt of ligninsulfonic acid, dodecylsulfuric ester or the sulphate mixture of fatty alcohol prepared from natural fatty acids.

This group also includes salts of sulfuric esters and additions of sulfonic acids of fatty alcohols / ethylene oxide. The benzimidazole sulfonated derivatives preferably have two sulfonyl groups and one fatty acid radical having about 8 to 22 carbon atoms. Examples of alkylarylsulfonates are sodium salts, calcium salts, or triethanolammonium salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or naphthalenesulfonic acid / formaldehyde condensation product. Other possible substances are phosphates, such as the phosphoric ester salts of the p-nonylphenol adduct with 4-14 moles of ethylene oxide, or phospholipids.

Typically, the compositions comprise 0.1 to 99%, in particular 0.1 to 95% of the active ingredient and 1 to 99%, in particular 5 to 99%, of at least one auxiliary liquid, and typically, O to 25 %, in particular Q, 1 to 20%, of the compositions may be surfactants,% in each case means percentage by weight. While concentrated compositions are more commercially preferable, the final consumer typically uses diluted compositions whose concentrations of active ingredient are much lower. Preferred compositions are, in particular, formed as follows,% represents weight percent.
