Heterocyclic compounds known from the literature which contain a nitroguanidine structure are known from EP-A-192,060 as insecticides. However, the biological •* properties of these compounds are not entirely satisfactory in pest control. The individual compounds excluded from the definition of the formula I are described in the literature as intermediates for pharmaceutically active compounds with antileukaemic and antimicrobial actions. These compounds likewise have the biological properties of the remaining substances of the formula I. When used in agrochemicals and as active /' substance in agrochemicals, they are therefore likewise a subject of the present invention.
The compounds of the formula I according to the invention also include the salts with agrochemically acceptable inorganic acids. Examples of such acids are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid and nitric acid, and acids which have the same central atom and higher or lower oxidation levels, such as perchloric acid, nitrous acid or phosphorus acid.
If at least one of the radicals Rlt R3 or R4 is hydrogen, the compounds of the formula I can also exist in the tautomeric forms la or lb.

one hetero atom as a ring member, i.e. at least one of the atoms which forms the ring-shaped basic body on which the ring systems are based is other than carbon. In principle, all atoms of the periodic system of the elements are capable of acting as ring members if they can form at least two covalent bonds, in which case the heterocyclic radical is preferably unsaturated and bonded via a carbon atom as a ring member to the basic body of the nitroguanidine of the formula I. Unsaturated ring systems of the definition A contain one or more double bonds, and such ring systems are preferably polyunsaturated and generally have aromatic character. Ring systems which contain at least one nitrogen atom as the hetero atom are preferred. Such rings af the definition A customarily contain one to three hetero atoms from the series comprising oxygen, sulfur and nitrogen, the maximum of oxygen or sulfur atoms in each case being one. Preferred ring systems made the definition of A being those where the heterocyclic radical A contains one to three hetero atoms from the scries comprising oxygen, sulfur and nitrogen, where one hetero atom is always nitrogen and the maximum of oxygen atoms or sulfur atoms being one. In particular, examples of heterocycles of the definition A according to the invention can be found in the group of basic bodies of the following structures:

In the above formulae, E is Ci-C3alkyl and Y is hydrogen, Ci-C3alkyl or cyclopropyl.
The heterocycles A which were listed as examples can be unsubstituted or, depending on the substitution possibilities of the ring system, carry up to four substituents such as are indicated under formula I. These heterocycles arc preferably bonded to the guanidine body via a carbon atom in their unsubstituted form, or they carry one to three substituents from the group comprising halogen, CrC3alkyl, CrC3haloalkyl, Ci-C3haloalkoxy or Ci-C3alkoxy. Very particularly preferred heterocycles A are pyridyl radicals or thiazolyl radicals, for example 3-pyridyl, 2-halopyrid-5-yl, 2,3-dihalopyrid-5-yl, 2-halothiazol-4-yl, l-oxopyrid-3-yl, l-oxo-2-halopyrid-5-yl and l-oxo-2,3-dihalopyrid-5-yl.
In the definition of the formula I according to the invention, the individual generic terms are to be understod as follows:
The halogen atoms suitable as substituents are fluorine and chlorine as well as bromine and iodine, preferred substituents being fluorine, chlorine and bromine. Halogen here is to be understood as a substitucnt in its own right or as part of a substituent such as in haloalkyl, haloalkylthio, haloalkoxy, halocycloalkyl, haloalkenyl, haloalkynyl, haloallyloxy or haloallyhhio. The alkyl, alkylthio, alkenyl, alkynyl and alkoxy radicals suitable as substituents can be straight-chain or branched. Examples of such alkyls which may be mentioned are methyl, ethyl, propyl, isopropyl, butyl, i-butyl, sec-butyl or tert-butyl. Suitable alkoxy radicals which may be mentioned, inter alia, are: methoxy, ethoxy, propoxy, isopropoxy or butoxy and their isomers. Alkylthio for example is methylthio, ethylthio, isopropylthio, propylthio or the butylthio isomers. If the alkyl, alkoxy, alkenyl, alkynyl orcycloalkyl groups suitable as substituents are substituted by halogen, they can be partially halogenated or even perhalogenated, in which case the definitions given above hold for halogen, alkyl and alkoxy. Examples of the alkyl elements of these groups are methyl which is monosubstituted to trisubstituted by fluorine, chlorine and/or bromine, for example CHF2 or CF3; ethyl which is monosubstituted to pentasubstituted by fluorine, chlorine and/or bromine, for example CH2CF3, CF2CF3, CF2CC13, CF2CHC12, CF2CHF2, CF2CFC12, CF2CHBr2, CF2CHC1F, CF2CHBrF or
2 3 5 2
CC1FCHCIF; propyl or isopropyl, cach of which is monosubstituted to heptasubstitutcd by fluorine, chlorine and/or bromine, for example CH2CHBrCH2Br, CF2CHFCF3, CH2CF2CF3 or CH(CF3)2; butyl which is monosubstituted to nonasubstituted by fluorine, chlorine and/or bromine, or one of its isomers, for example CF(CF3)CHFCF3 or CH2(CF2)2CF3; 2-chlorocyclopropyl or 2,2-difluorocyclopropyl; 2,2-difluorovinyl, 2,2-dichlorovinyl, 2-chloroalkyl, 2,3-dichlorovinyl or 2,3-dibromovinyl.
If the defined alkyl, alkoxy or cycloalkyl groups are substituted by other substituents, they can be monosubstituted or polysubstituted by an identical or by different substituents from among those mentioned. Preferably, one or two further substituents are present in the substituted groups. Cylcoalkyl radicals which are suitable as substituents arc, for example, cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl. Alkenyl and alkynyl groups contain one unsaturated carbon-carbon bond. Typical representatives are allyl, methallyl or propargyl, but also vinyl and ethynyl. The double or triple bonds in allyloxy, propargyloxy, allylthio or propargylthio are separated from the site where they are linked to the hetero atom (O or S) preferably by a saturated carbon atom.
Sub-groups which must be emphasized from among the compounds of the formula 1 are those in which either a) Rt and R3 independently of one another are hydrogen, methyl, ethyl or cyclopropyl, or b) R2 is hydrogen, or c) R4 is hydrogen or methyl.
In the event that R4 is the group -CHR5-B, those compounds in which R5 is hydrogen are preferred. The preferred embodiments of B are phenyl, pyridyl or thiazolyl, each of which is unsubstituted or substituted by one to three radicals from the group comprising halogen, C[-C3alkyl, C1-C3haloalkyl, Q-Gjhaloalkoxy or Cj-Gjalkoxy.
In a particularly preferred group of compounds of the formula I, Rj and R3 independently of one another are hydrogen, methyl, ethyl or cyclopropyl, R2 is hydrogen, R4 is hydrogen or methyl, and A is pyridyl, 1-oxopyridyl, thiazolyl, or pyridyl, 1-oxopyridyl or thiazolyl, each of which is substituted by one to three substituents from the group comprising halogen, Ci-C3alkyl, CrC3haloalkyl, CpCjhaloalkoxy or Ci-C3alkoxy.
The following are to be mentioned as preferred individual compounds of the formula I: l-(2-chloropyrid-5-ylmethyl)-l-methyl-2-nitroguanidine,

Variant a) of the process (II + II —> I) according to the invention is advantageously carried out in an inert solvent at temperatures between 0°C and +150°C, in particular between +40°C and +120°C. Solvents which are particularly suitable are alcohols such as methanol, ethanol or isopropanol. Variant b) (IV + V —> I) is advantageously carried out in an inert polar aprotic solvent such as acetonitrile or dimethylformamide, at temperatures between +50°C and the boiling point of the reaction mixture. Suitable bases are carbonates such as potassium carbonate. Hydrides such as sodium hydride can also be employed as bases. When sodium hydride is employed in acetonitrile or dimethylformamide, it is possible to lower the reaction temperature to +10°C to +25°C, without this resulting in a considerably longer reaction time. II is advantageously reacted with VI in aqueous, alcoholic solutions at temperatures between 0°C and +25°C. In this reaction, N-nitrosomethylamine is formed as a by-product II is customarily reacted with VII in an aqueous medium at temperatures between +40°C and +100°C, preferably between +60°C and +80°C.

R3-Hal or R4-Hal in which Rj, R3 and R4 have the meanings given under formula I which are not hydrogen, and Hal is halogen, preferably chlorine or bromine.
Since it is known that alkylation reactions of the above type hardly ever proceed
2 3 5 ?
regiospccifically, this alkylation step is preferably suitable for preparing tertiary amino groups, i.e. in particular for those cases in which all three remaining hydrogen atoms are to be substituted simultaneously on the guanidine nitrogen atoms by radicals Rj, R3 and R4 of the same type.
On the other hand, with alkylations of the above type it is possible to obtain in a simple manner those guanidine derivatives of the formula I in which all radicals Rj, R3 and R4 have a meaning other than hydrogen, if it is desired to introduce only one of these radicals in each case, in place of a hydrogen atom. If sterical hindering is sufficiently effective by either the radicals present in the guanidine structure, such as -CHR2-A, or the radicals Rj, R3 or R4 to be introduced, the alkylation reaction of this type can still be used for preparing secondary guanidine amino groups. If the compounds of the formula la are reacted only with one or two equivalents of alkylation reagent, the results are mixtures of isomers as well as alkylation products having different degrees of alkylation. However, these mixtures can be separated into their individual components using customary separation methods, so that, inter alia, it is also possible to select the desired product.
The reaction conditions chosen for the alkylation reactions mentioned are a temperature between 0°C and +150°C, preferably between +10°C and +50°C. Suitable bases are alkali metal hydrides and alkaline earth metal hydrides, such as sodium hydride or calcium hydride, or carbonates, such as sodium carbonate or potassium carbonate. The alkylation reaction is preferably carried out in a polar, aprotic solvent, such as acetonitrile or dimethylformamide.
The intermediates of the formulae II, III, IV, V, VI and VII are known or can be prepared in analogy to known processes.
It has now been found that the compounds of the formula I according to the invention are valuable active substances in pest control and are well tolerated by warm-blooded species, fish and plants. In particular, the use of the active substances according to the invention relates to insects and arachnids which occur in crop plants and ornamental plants in agriculture, in particular in cotton, vegetable and fruit plantations, in forests, in the protection of stored products and materials, and in the hygiene sector, in particular on domestic animals and productive livestock. They are active against all or individual stages of development of normally sensitive, but also resistant species. In this context, their action can become apparent by direct destruction of the pests or only after some time, for

The good pesticidal action of the compounds of the formula I according to the invention
corresponds to a destruction rate (mortality) of at least 50-60 % of the pests mentioned.
The action of the compounds according to the invention and of the compositions containing them can be broadened considerably by adding other insecticides and/or acaricides, and it can be adapted to suit the given circumstances. Examples of suitable additives are representatives of the following classes of active substances: organophosphorus compounds, nitrophcnols and derivatives, formamidines, ureas, carbamates, pyrethroids, chlorinated hydrocarbons and Bacillus thuringiensis preparations.
The compounds of the formula I are employed in unaltered form or, preferably, together with the auxiliaries conventionally used in the art of formulation, and they can therefore be processed in a known manner to give, for example, emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules and also encapsulations in polymeric substances. The application methods such as spraying, misting, dusting, scattering or pouring, as well as the compositions, are selected to suit the intended aims and the prevailing conditions. The compounds of the formula I are furthermore suitable for use in seed treatment, in which case the seed can be treated or dressed with the active substance or with a formulation containing the active substance before sewing or the active substance can be applied to the seed furrow during sowing.
The formulation, i.e. the compositions, preparations or formulations containing the active substance of the formula I or combinations of these active substances with other insecticides or acaricides, and, if desired, a solid or liquid additive, are prepared in a known manner, for example by intimately mixing and/or grinding the active substances with extenders, for example with solvents, solid earners, and, if desired, surface-active compounds (surfactants).
The following are suitable as solvents: aromatic hydrocarbons, preferably the fractions Q to C12 of alkylbenzenes such as xylene mixtures or alkylated naphthalenes, aliphatic or cycloaliphatic hydrocarbons, such as cyclohexane, paraffins or tetrahydronaphthalene, alcohols such as ethanol, propanol or butanol, and glycols as well as their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones such as cyclohexanone, isophorone or diacetanol alcohol, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, or water, vegetable oils such as rapeseed oil,
4
castor oil, coconut oil or soya oil; silicone oils may also be suitable.
Solid carriers which are generally used, for example for dusts and dispersiblc powders, are ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silicas or highly-disperse absorptive polymers. Suitable paniculate, adsorptive carriers for granules arc porous types, for example pumice, brick grit, scpiolite or bentonitc, and also non-sorptive carrier materials, such as calcite or sand. Moreover, a large number of granulated materials of inorganic or organic nature can be used, such as, in particular, dolomite or comminuted plant residues.
Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and welting properties, depending on the nature of the active substance of the formula 1 to be formulated or on the combinations of these active substances with other insecticides or acaricides. Surfactants are also to be understood as meaning mixtures of surfactants.
Anionic surfactants which are suitable can be either so-called water-soluble soaps or water-soluble synthetic surface-active compounds.
Suitable soaps are the alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts of higher fatty acids (C10-C22). such as the sodium salts or potassium salts of oleic or stearic acid, or of natural mixtures of fatty acids which can be obtained, for example, from coconut or tallow oil. Mention must also be made of the fatty acid methyltaurinates as surfactants.
■+J* However, so-called synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.
The fatty sulfonates or fatty sulfates are generally in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts, and generally have an alkyl radical having 8 to 22 C atoms, alkyl also including the alkyl moiety of acyl radicals, for example the sodium or calcium salt of ligninsulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonyl groups
and one fatty acid radical having about 8-22 C atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensation product. Other suitable compounds are the corresponding phosphates, such as the salts of the phosphoric ester of a p-nonylphenol/(4-14)-ethylenc oxide adduct, or phospholipids.
Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols. Other non-ionic surfactants which are suitable are the water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and which contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The abovementioned compounds customarily contain 1 to 5 ethylene glycol units per propylene glycol unit.
Examples of non-ionic surfactants which may be mentioned are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other suitable substances are fatty acid esters of polyoxyethylenesorbitan, such as polyoxyethylenesorbitan trioleate.
The cationic surfactants are mainly quaternary ammonium salts which contain at least one alkyl radical having 8 to 22 C atoms as N-substituents and which have lower halogenated or free alkyl, benzyl or lower hydroxyaLkyl radicals as further substinients. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, for example stearyltrimeihylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.
The surfactants customary in the art of formulation are described, for example, in the following publication :
"Mc Cutcheon's Detergents and Emulsifiers Annual", Mc Publishing Coq
NJ, USA, 1988.

As a rule, the pesticidal preparations contain 0.1 to 99 %, in particular 0.1 to 95 %, of the active substance of the formula I or combinations of this active substance with other insecticides or acaricides, 1 to 99.9 % of a solid or liquid additive and 0 to 25 %, in particular 0.1 to 25 %, of a surfactant. While concentrated compositions are often preferred as commercially available goods, the end user generally uses dilute preparations containing considerably lower concentrations of active substance. Typical application concentrations are between 0.1 and 1,000 ppm, preferably between 0.1 and 500 ppm. The applicadon rates per hectare are generally 1 to 1,000 g of active substance per hectare, preferably 25 to 500 g/ha.
In particular, preferred formulations have the following composition: (% = percent by weight)
Emulsifiable concentrates
Active ingredient: 1 to 90 %, 5 to 20 % being preferred
Surface-active agent: 1 to 30 %, preferably 10 to 20 %

Granules:
Active ingredient: Solid carrier:
0.5 to 30 %, preferably 3 to 15 % 99.5 to 70 %, preferably 97 to 85 %
The compositions can also contain further additions such as stabilizers, for example epoxidized or unepoxidized vegetable oils (epoxidized coconut oil, rapeseed oil or soya oil), defoamers, for example silicone oil, preservatives, viscosity regulators, binders, tackifiers and also fertilizers and other active substances for achieving specific effects.
The examples which follow are intended to illustrate the invention. They do not restrict the invention.
Preparation examples
Example H1: l-(2-chloronvrid-5-ylmethvl)-1 -methyl-2-nitroguanidine
A mixture of 3.2 g of N-methyl(2-chloropyrid-5-yl)methylamine, 2.7 g of S-methyl N-nitroisothiourea, 0.2 g of potassium hydrogen sulfate and 75 ml of ethanol is refluxed for 4.5 hours. The reaction mixture is filtered while hot. When the filtrate has cooled to 0°C, the crude product crystallizes. Recrystallization from ethanol results in pure l-(2-chloropyrid-5-ylmethyl)-l-methyl-2-nitroguanidine in the form of a colourless crystallizate having a melting point of 163-165°C.
Example H2: l-(2-chloropvrid-5-vlmethvl)-2-nitroguanidine
A suspension of 4.0 g of nitroguanidine and 5.4 g of (2-chloropyrid-5-yl)methylamine in 80 ml of water is heated for 3 hours at +80°C. When the reaction mixture has cooled to +20°C,
23 5 2
thc product is precipitated within 16 hours in the form of a colourless crystallizatc. The crystal powder is separated off, washed with methanol and dried. This gives 2.0 g of l-(2-chloropyrid-5-ylmethyl)-2-nitroguanidinc having a melting point of 195-197°C.
ExampleH3: l-(2-chloropyrid-5-vlmethvO-2-(4-chlorobenzvl)-l-methvl-3-nitroguanidine
I
NOi
To a solution of 4.0 g of l-(2-chlorpyrid-5-ylmethyl)-l-methyl-2-nitroguanidine in 50 ml of dimethylformamide there is added at 10-15°C 0.7 g of 55 % sodium hydride in small portions. After 20 minutes, a solution of 2.65 g of 4-chlorobenzyl chloride in 5 ml of dimethylformamide is added dropwise at 10-15°C. The reaction mixture is stirred for 20 hours at room temperature and then poured into 200 ml of ice-water. The aqueous solution is extracted using chloroform. The organic phase is separated off, dried and evaporated. Purification by column chromatography on silica gel gives l-(2-chloropyrid-5-ylmethyl)-2-(4-chlorobenzyl)-l-methyl-3-nitroguanidine having a melting point of 130-132°C.
