Description: HERBICIDAL 1 , 2, 4, 6-THIATRIAZINES The present invention relates to novel herbicidally active thiatriazine derivatives, to processes for their preparation, to compositions comprising these compounds, and to then- use for controlling weeds, especially in crops of useful plants or for inhibiting plant growth. Thiatriazine compounds are described, for example, in Chem. Ber. 121, 383-386 (1988), Z. Naturforsch. 43, 763-768 (1988), Chem. Ber. 126, 2601-2607 (1993), J. Am. Chem. Soc. 1989, 111, 1180-1185, DD 113 006 and in the PhD thesis of W. Jϋrgler, Philipps-University Marburg Lahn, 1988 ("lλ 4 - und lλ 6 -2.4.6-Thiatriazine aus Sulfodiimiden" ["lλ 4 - and lλ 6 -2,4,6-thiatriazines from sulfodiimides]). There has now been found a novel and simple synthetic method for preparing novel thiatriazine derivatives which are substituted by a variety of substituents. Advantages of this synthetic method are not only the ready accessibility of thiatriazine derivatives which are substituted by a variety of substituents, but also the low number of synthetic steps (converging). In addition, the herbicidal and growth-inhibiting properties of the thiatriazine derivatives were found for the first time. The present invention therefore provides compounds of the formula I in which R_ is C r C 2 oalkyl .

y' The alkyl groups in the definitions of the substituents can be straight-chain or branched and are, for example, methyl, ethyl, propyl, butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tetradecyl, hexadecyl, octadecyl or eicosyl, and the branched isomers of these. Alkoxy, alkenyl and alkynyl radicals are derived from the abovementioned alkyl radicals. The alkenyl and alkynyl radicals can be mono- or polyunsaturated. Suitable cycloalkyl substituents have 3 to 8 carbon atoms and are, for example, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl or cyclooctyl. The corresponding cycloalkenyl substituents can be mono- or else polyunsaturated, for example cyclopentadienyl or cyclooctatetraenyl. If alkyl, alkenyl or alkynyl are substituents on a cycloalkyl, cycloalkenyl, phenyl, biphenyl, naphthyl or heterocyclyl, these ring systems can also be polysubstituted by alkyl, alkenyl or alkynyl. Halogen is, as a rule, fluorine, chlorine, bromine or iodine. The same also applies to halogen in connection with other meanings, such as haloalkyl or halophenyl. Heterocyclyl is to be understood as meaning ring systems which, in addition to carbon atoms, have at least one hetero atom, such as nitrogen, oxygen and/or sulfur. They can be saturated or unsaturated. Such ring systems preferably have 3 to 8 ring atoms. This also applies to those heterocycles which are formed by 2 substituents bonded to a nitrogen atom, as is the case in groups such as -NR 10 RJJ. Preferred heterocycles Rj which are suitable are, for example, oxiranyl, dioxolanyl, dioxanyl, 2,3-dihydro[l,4]dioxinyl, pyrrolidinyl, piperidinyl, morpholinyl, thiomorpholinyl, pyridinyl, pyrimidinyl, pyrrolyl, imidazolyl, tetrahydrofuranyl, tetrahydropyranyl, dihydrofuranyl, thiophenyl, 2,3-dihydrothiophenyl, tetrahydrothiophenyl and dihydropyranyl. Heterocyclyl as a substituent of a group R can be, for example, oxiranyl, dioxolanyl, pyrrolidinyl, piperidinyl, morpholinyl, pyridinyl, imidazolyl, tetrahydrofuranyl, tetrahydropyranyl, dihydrofuranyl, dihydropyranyl or phthalimidyl. Heterocycles R 6 are preferably, inter alia, pyridinyl, pyrimidinyl and triazinyl. Preferred heterocycles R 7 are, for example, oxetanyl, pyridyl, thiophenyl and furanyl. R 8 and R 9 preferably form rings such as piperidinyl, morpholinyl and pyrrolidine. Preferred examples of heterocycles formed by R 10 and R j j , or R 2 and R 3 , together with the nitrogen atom to which these radicals are bonded, are piperidinyl, morpholinyl, pyrrolidinyl and imidazolyl. Heterocycles R 9 are preferably thiophenyl, furanyl, pyridinyl and oxetanyl. Phenyl and naphthyl rings R can be substituted by carbo- or heterocyclic radicals which are formed by 2 adjacent substituents from these phenyl or naphthyl rings. The carbocycles have preferably 4 to 6 carbon atoms, such as cyclobutyl, cyclopentyl and cyclohexyl. Suitable heterocyclic groups are, in particular, dioxolanyl and tetrahydrofuranyl . Heterocycles R such as succinimidyl, pyridinyl, thiophenyl or furanyl can have fused to them carbocycles, such as phenyl or cyclohexenyl. Heterocycles R 2 and R 3 are preferably pyridinyl, pyrrolidinyl and pyrimidinyl. Heterocycles formed by -NR 2 R 3 encompass, for example, succinimidyl, imidazolyl and triazolyl, it being possible for such groups to have fused to them carbocycles, such as phenyl or cyclohexene. Heterocyclylcarbonyl R 2 or R 3 is, for example, pyridinyl, pyrrolidinyl, triazolyl, thiophenyl, furanyl or isoxazolyl. In substituents such as -N=C(C 1 -C 4 -alkyl) 2 , the alkyl radicals can be identical or different. They are preferably identical. The same also applies to the alkyl radicals in dialkylamino, dialkylaminocarbonyl, trialkylammonium and trialkylsilyl substituents. In the definitions cyanoalkyl, alkoxycarbonyl, alkylcarbonyloxy, alkylcarbonyl, alkylcarbonylamino, alkylaminocarbonyl, dialkylaminocarbonyl, alkoxycarbonylalkoxy and alkenylcarbonyl, the cyano or carbonyl carbon atom is not included in the upper and lower limits of the number of carbon atoms in each case specified. Suitable alkali metals and alkaline earth metals are, for example, lithium, sodium, potassium, magnesium, calcium or barium. The invention also encompasses the salts which the compounds of the formula I can form, in particular with amines, alkali metal bases and alkaline earth metal bases or quaternary ammonium bases. Salt formers amongst the alkali metal hydroxides and alkaline earth metal hydroxides are, in particular, the hydroxides of lithium, sodium, potassium, magnesium or calcium, but especially those of sodium or potassium. Examples of amines which are suitable for the formation of ammonium salts are ammonia as well as primary, secondary and tertiary Cj-C 18 alkylamines, Cj- hydroxyalkylamines and C 2 -C 4 alkoxyalkylamines, for example methylamine, ethylamine, n-propylamine, isopropylamine, the four butylamine isomers, n-amylamine, isoamylamine, hexylamine, heptylamine, octylamine, nonylamine, decylamine, pentadecylamine, hexadecylamine, heptadecylamine, octadecylamine, methylethylamine, methylisopropylamine, methylhexylamine, methylnonylamine, methylpentadecylamine, methyloctadecylamine, ethylbutylamine, ethylheptylamine, ethyloctylamine, hexylheptylamine, hexyloctylamine, dimethylamine, diethylamine, di-n-propylamine, di-isopropylamine, di-n-butylamine, di-n-amylamine, di-isoamylamine, dihexylamine, diheptylamine, dioctylamine, ethanolamine, n-propanolamine, isopropanolamine, N,N-diethanolamine, N-ethylpropanolamine, N-butylethanolamine, allylamine, n-butenyl-2-amine, n-pentenyl-2-amine, 2,3-dimethylbutenyl-2-amine, dibutenyl-2-amine, n-hexenyl-2-amine, propylenediamine, trimethylamine, triethylamine, tri-n-propylamine, tri-isopropylamine, tri-n-butylamine, triisobutylamine, tri-sec-butylamine, tri-n-amylamine, methoxyethylamine and ethoxyethylamine; heterocyclic amines, for example pyridine, quinoline, isoquinoline, morpholine, piperidine, pyrrolidine, indoline, quinuclidine and azepine; primary arylamines, for example anilines, methoxyanilines, ethoxyanilines, o, m, p-toluidines, phenylenediamines, benzidines, naphthylamines and o, m, p-chloroanilines; but in particular triethylamine, isopropylamine and di-isopropylamine. The compounds of the formula I have an asymmetric centre in the sulfur atom of the thiatriazine ring. This is why the preparation of these compounds gives racemates, which can be separated into the corresponding enantiomers by customary separation methods. If the substituents of the thiatriazine ring have further asymmetric centres, it is also possible to separate the corresponding diastereoisomers in the customary manner. The present invention also encompasses such diastereoisomers and enantiomers.

Amongst these, particularly preferred compounds are those in which X is O or S, and R 4 is methyl which is substituted by halogen or cyano, or R 4 is C 2 -C 8 alkyl, C 2 -C 8 alkenyl, C 3 -C 8 alkynyl, C 3 -C 8 cycloalkyl, C 5 -C 8 cycloalkenyl, C 3 -C 8 cycloalkyl-Cj-C 4 alkyl or Cj-C 4 alkyl-C 3 -C 8 cycloalkyl, it being possible for these substituents to be unsubstituted or substituted by halogen or cyano, or R is phenyl which is substituted by halogen, cyano, nitro, amino, C j -C 4 alkyl, C j -C alkyloxy, Cj-C alkylthio, Cj-C haloalkyl, C j -C 4 haloalkoxy, C 2 -C 6 alkoxycarbonylalkoxy, C j -C alkylsulfonyl, C j -C 6 alkyloxycarbonyl, C j -C 6 alkylcarbonyl, formyl, Cj-C 4 alkylamino, C 2 -C 6 dialkylamino, C 3 -C 6 trialkylsilyl or C 2 -C 6 alkylcarbonyloxy, or R 4 is biphenyl, naphthyl, heterocyclyl, C j -C 4 alkylphenyl, C j -C 4 alkylnaphthyl, phenyl-C j -C alkyl or naphthyl-Cj-C 4 alkyl, it being possible for these substituents to be unsubstituted or substituted by halogen, cyano, nitro, amino, C j -C 4 alkyl, C j -C alkyloxy, Cj-C 4 alkylthio, Cj-C 4 haloalkyl, Cj-C 4 haloalkoxy, C 2 -C 6 alkoxycarbonylalkoxy, C j -C 4 alkylsulfonyl, C j -C 6 alkyloxycarbonyl, C j -C 6 alkylcarbonyl, C 3 -C 6 trialkylsilyl or C j - C 6 alky lcarbony loxy . Very particularly preferred compounds of the formula I are those in which X is O, and R 4 is phenyl which is substituted by halogen, cyano, nitro, amino, Cj-C alkyl, C j -C 4 alkyloxy, C j -C 4 alkylthio, C C 4 haloalkyl, halomethoxy, C j -C 4 alkylsulfonyl, Cj-C 4 alkylamino or C 2 -C 6 dialkylamino. The compounds of the formula I can be prepared, on the one hand, via process steps which are known per se using known starting materials, and, on the other hand, via a process which was not known per se. The latter process, which was not known per se, comprises starting from the trihalogenated thiatriazine of the formula II in which Hal substituents independently of one another are fluorine, bromine or, in particular, chlorine, this thiatriazine together with its preparation being described in Chem. Ber. (1991) 124, 1347-1352 and Z. Chem. 16 (1976) 358-359, and reacting it, to introduce the substituent Rj, with the corresponding organometal compound of the formula III in which Rj is as defined above and M is a monovalent or polyvalent metal atom which, depending on the valency, can carry a corresponding number of R j groups. Examples of suitable metals are, in particular, lithium, magnesium, zinc, aluminium, silicon and tin, and furthermore also manganese and titanium. The polyvalent metal atoms can also carry, besides one or more Rj groups, further substituents such as halogen, cyano, C 1 -C alkyl or tetrafluoroborate. The organometal compound of the formula HI can furthermore be used in combination with salts, such as aluminium chloride, tin chloride, zinc chloride or cerium chloride, or aluminium bromide, zinc bromide and/or copper bromide, amongst which aluminum chloride, aluminium bromide, zinc chloride and zinc bromide are preferred. The compounds of the formula IH can be prepared by customary methods, for example by reacting the corresponding halide Rj -halogen with the metal M, if appropriate with an addition of a metal halide, or by halogen/metal exchange of R r Br or R -I with a reactive organometal compound, for example butyllithium, and reaction with a compound of the metal M which carries at least one leaving group, such as halogen, or by abstraction of a proton of the molecule Rj-H with a strong base, for example a metal alkoxide, for example potassium tert-butoxide, or metal hydride, for example sodium hydride or lithium aluminium hydride, or a metal amide, for example lithium diisopropylamide, or, in particular, an organometal compound, for example butyllithium, and treatment with a compound of the metal M which carries at least one leaving group, for example cyano, alkoxy or, in particular, halogen, and, if appropriate, one or more Cj-C 4 alkyl groups. Introduction of the R group can be effected in an aprotic solvent, such as a hydrocarbon, for example hexane, heptane or toluene, or an ether, such as dioxane, diethyl ether or, in particular, tetrahydrofuran, at temperatures from -100°C to 150°C, in particular -80°C to 50°C (depending on the solvent). To prepare the compounds of the formula IV in which the sulfur atom of the thiatriazine is bonded to an aromatic or heteroaromatic part of R j , the reaction of the corresponding compound R j -H with a compound of the formula II can be carried out under the conditions of a Friedel-Crafts reaction, i.e. in the presence of a Lewis acid, for example aluminium trichloride, zinc chloride or tin tetrachloride, in an aprotic solvent, for example benzene, nitrobenzene or dichloromethane. In the case of compounds of the formula I in which R j additionally to the abovementioned definitions is also a group of the formula IX or X in which A is hydrogen, fluorine, chlorine, bromine, iodine, C -C 7 alkyl, C -C / alkyl which is substituted by halogen or Cj-C 3 alkoxy, or C j -C 4 alkoxy; B is hydrogen, fluorine, chlorine, bromine, iodine, Cj-C 7 alkyl, C r C 7 alkyl which is substituted by halogen or C -C 3 alkoxy, or Cj-C 4 alkoxy; G is hydrogen, Cj-C 7 alkyl, C j -C 7 alkyl which is substituted by halogen or Cj-C 3 alkoxy, Cj-C 4 alkoxy or trimethylsilyl; D is fluorine, chlorine, bromine, iodine, Cj-C 6 alkoxy, Cj-Cgalkylthio, thiocyanato, cyano or C -C 5 alkylcarbonyloxy; and E is C j -C 8 alkyl, C j -C 8 alkyl which is substituted by Cj-C 4 alkoxy, acetoxy, benzyloxy or halogen, C 3 -C 8 cycloalkyl, C 3 -C 8 cycloalkyl which is substituted by C -C 4 alkoxy, acetoxy, benzyloxy or halogen, Cj-C 5 alkylcarbonyl, C 6 -C 8 aryl or (C j -C alkyl) 3 silyl, the compounds of the formula IV can be prepared advantageously from compounds of the formula XI in which the substituents A and E, A and B, A and G, and G and E in each case together can form a ring, for example ; in which RQ is C r C 3 alkyl, C j -C 3 alkoxy, acetoxy, benzyloxy or halogen; and n 0 is 0, 1, 2 or 3, by reacting the compound of the formula XI with a compound of the formula II in the presence or absence of a Lewis acid, for example aluminium trichloride, zinc chloride or tin tetrachloride, in an aprotic solvent, for example hexane, dichloromethane, chloroform, carbon tetrachloride, 1,2-dichloroethane, ether or tetrahydrofuran, at temperatures from -78°C to the boiling point of the solvent, but in particular at -40°C to +40°C, and, if desired, the crude product obtained is subsequently treated with an acid-binding agent, such as tertiary amine, for example triethylamine or pyridine, or a mineral base, for example sodium hydrogen carbonate, sodium carbonate or potassium carbonate, if appropriate in aqueous solution, to neutralize the acid H-halogen. If the reactivity of the substituent R in the compound of the formula I makes difficult the preparation of the organometal compound of the formula HI, then this labile functional group R j can advantageously be protected and subsequently re-eliminated at the level of the compounds of the formulae IV, VI, VIII or I, analogously to the procedure described in, for example, 'Protective Groups in Organic Synthesis', Editors Th. W. Greene and P. G. M. Wuts, Wiley Interscience, 1991. For example, a) an alcohol can be protected in the form of a tert-butyl dimethylsilyl ether, and this protective group can be re-eliminated with tetrabutylammonium fluoride; or b) a carbonyl group can be protected in the form of 1,3-dioxane and then again hydrolyzed under acidic conditions to give the carbonyl group; or c) a carboxylic acid can be protected in the form of the ortho-ester and then be recovered under aqueous-acidic and subsequently basic conditions. The reactive substituents in Rj in the compounds of the formula I can also be introduced by known methods from less reactive precursors at the level of the compounds of the formulae IV, VI, VIII or I, for example by the method described in 'Advanced Organic Chemistry: Reactions, Mechanisms and Structure', Editor J. March, McGraw-Hill, 1983, or in 'Comprehensive Organic Transformations', Editor R. C. Larock, VCH, 1989. Such less reactive precursors can be, for example, halogens, such as bromine, chlorine or iodine, carbon-carbon double or triple bonds, or ethers or thioethers. A large number of suitable conversion reactions for the preparation of functional groups is described in the specialist literature. For example, a) a halide can be converted by reduction to give the corresponding alkane or by nucleophilic substitution to give the corresponding nitrile, ether, thioether, ester, azide or thiocyanate; or b) a carbon-carbon double bond can be hydrogenated, halogenated on the allyl position, oxidized to give the corresponding epoxide or cis-diol, or subjected to ozonolysis to give the carbonyl derivative or to oxidative hydroborination to give the alkanol; or c) a nitrile group can be hydrolyzed to give the carboxamide or the carboxylic acid; or d) a thioether can be oxidized to give the sulfoxide or the sulfone, it being possible for these latter compounds to be deprotonated in the α-position and further reacted with electrophilic reagents; or e) an azide can be reduced to give the corresponding amine and, if desired, subsequently acylated. The resulting compounds of the formula IV are novel and thus also provided by the present invention. The substituents -NR 2 R 3 - and -XR 4 can then be introduced into the compound of the formula IV in any desired sequence. The reaction of the compounds of the formula IV with the compounds of the formula V H-XR 4 (V), in which X and R are as defined above, to give the compounds of the formula VI is advantageously carried out in such a way that, prior to the reaction with the compounds of the formula IV, the compounds of the formula V are pretreated with a base, such as a metal hydride, for example lithium hydride, sodium hydride or potassium hydride, a metal hydroxide, such as sodium hydroxide or potassium hydroxide, or a basic salt such as sodium carbonate or potassium carbonate, preferably in equivalent amounts. Alternatively, it is also possible to treat the reaction mixture of the compounds of the formulae IV and V with the abovementioned bases. Solvents which are suitable for this step are hydrocarbons such as hexane or toluene, halogenated hydrocarbons such as chlorobenzene, ethers such as tetrahydrofuran, dioxane or diethyl ether, and tertiary amides, such as dimethylformamide. It is also possible to employ a mixture of these solvents with water, in which case it is advantagoeus to use a phase transfer catalyst. As a rule, the reaction temperatures are between -50°C and 100°C, preferably between 0°C and 40°C. The compounds of the formula V are known and can be prepared in a manner known to the expert. The compounds of the formula VI are novel and are also provided by the present invention. They can be converted into the end products of the formula I by means of a reaction with a compound of the formula VII M j -NR 2 R 3 (VII), in which R 2 and R 3 are as defined above and Mj is hydrogen or a metal atom such as lithium, sodium, potassium or calcium, the process advantageously being carried out in the presence of a base. If R 2 and/or R 3 are hydrogen, then Mj is preferably hydrogen. If R 2 or R 3 is an acyl group, Mj is preferably lithium, sodium or potassium. Solvents which are suitable for this reaction are hydrocarbons such as hexane or toluene, halogenated hydrocarbons such as chlorobenzene or dichloromethane, ethers such as diethyl ether, dioxane or tetrahydrofuran, alcohols such as ethanol or isopropanol, esters such as ethyl acetate, nitriles such as acetonitrile, or water. The reaction temperatures are in the range of -70°C to 100°C, in particular 0°C to 40°C. If Mj is hydrogen, an acid binder is preferably used for trapping the HHal acid. This can be, for example, a second equivalent of the compound of the formula VII or a tertiary amine such as triethylamine, pyridine or an inorganic base such as sodium carbonate, potassium carbonate or sodium hydrogencarbonate. In the event that R 2 , R 3 and M j are hydrogen, an excess of base can be used. The process may be carried out under pressure. The compounds of the formula VII and their preparation are described in the literature. The reaction conditions to be adhered to for the reaction of compound VI with compound VII must also be observed when the compound of the formula IV is first to react with the base of the formula VII. The resulting compounds of the formula VIE are also novel and provided by the present invention. The further reaction of the compounds of the formula VIE with the compounds of the formula V is effected analogously to the procedure in the reaction of the compounds of the formulae IV and V. However, an amine such as triethylamine is additionally added to the reaction mixture in amounts which range from catalytic to an excess. The end products of the formula I can be isolated in the customary manner by concentrating and/or evaporating the solvent and purified by recrystallization or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons, or by chromatographic methods. Conventional derivatization of compounds of the formula I allows other compounds of the formula I to be prepared. A variety of methods and techniques are suitable for the use according to the invention for the compounds of the formula I, IV, VI or VIII or for compositions comprising these compounds, for example the following: i) Seed dressing a) The seeds are dressed by shaking them, in a vessel, together with an active ingredient formulated as a wettable powder until the active ingredient is distributed uniformly on the seed surface (dry seed dressing). Up to 4 g of active ingredient of the formula I, IV, VI, VIII (in the case of a 50% formulation: up to 8.0 g of wettable powder) per kg seed is used. b) Seed dressing with an emulsion concentrate of the active ingredient or with an aqueous solution of the active ingredient of the formula I, IV, VI or VIE formulated as a wettable powder by method a) (wet seed dressing). c) Dressing by immersing the seed into a mixture comprising up to 1000 ppm of active ingredient of the formula I, IV, VI or VIII for 1 to 72 hours, if desired followed by drying of the seeds (seed soaking). Naturally, dressing the seed or treating the seedling which has just begun to germinate are the preferred methods of application because the treatment with the active ingredient is directed entirely towards the target crop. As a rule, 0.001 g to 4.0 g of active ingredient are used per kg of seed, it being possible to deviate from these limit concentrations up or down, depending on the method, which also makes possible the addition of other active ingredients or micronutrients (repeated dressing). ii) Controlled release of active ingredient The active ingredient is applied in solution to mineral granule carriers or polymerized granules (urea/formaldehyde) and allowed to dry. If desired, a coating can be applied additionally (coated granules) which allows controlled release of the active ingredient over a certain period. The compounds of the formula I, IV, VI or VIE can be used as pure active ingredients, i.e. as they are obtained in synthesis, but they are preferably processed in the customary manner together with the auxiliaries conventionally used in the art of formulation, for example to give emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules or microcapsules. The methods of application, such as spraying, atomizing, dusting, wetting, scattering or pouring, as well as the nature of the compositions, are chosen to suit the intended aims and the prevailing circumstances. The formulations, i.e. the compositions, preparations or combinations comprising the active ingredient of the formula I, IV, VI or VIII or at least one active ingredient of the formula I, IV, VI or VIE and, if desired, one or more solid or liquid additives, are prepared in a known manner, for example by intimately mixing and/or grinding the active ingredients with the additives, for example solvents or solid carriers. Furthermore, surface-active compounds (surfactants) can additionally be used for the preparation of the formulations. The following are suitable as solvents: aromatic hydrocarbons, in particular the fractions C 8 to C 12 , such as mixtures of alkylbenzenes, for example xylene mixtures or alkylated naphthalenes; aliphatic and cycloaliphatic hydrocarbons such as paraffins, cyclohexane or tetrahydronaphthalene; alcohols such as ethanol, propanol or butanol; glycols as well as their ethers and esters, such as propylene glycol or dipropylene glycol ether, ketones such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or water; vegetable oils as well as their esters, such as rapeseed oil, castor oil or soya oil; if appropriate, also silicone oils. Solid carriers which are used, for example, for dust and dispersible powders are, as a rule, ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silica or highly-disperse absorptive polymers. Possible paniculate, adsorptive carriers for granules are either porous types, for example pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carrier materials are, for example, calcite or sand. Moreover, a large number of pregranulated materials of inorganic or organic nature, such as, in particular, dolomite or comminuted plant residues, can be used. Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient of the formula I to be formulated. Surfactants are also to be understood as meaning surfactant mixtures. Suitable anionic surfactants can be either so-called water-soluble soaps or water-soluble, synthetic surface-active compounds. Soaps which may be mentioned are the alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts of higher fatty acids (C 10 -C 22 ) for example the sodium or potassium salts of oleic or stearic acid, or of natural mixtures of fatty acids which can be obtained from, for example, coconut oil or tallow oil. Mention must also be made of the fatty acid methyltaurinates. However, so-called synthetic surfactants are used more frequently, in particular fatty alcohol sulfonates, fatty alcohol sulfates, sulfonated benzimidazole derivatives or alky lary lsulf onates . As a rule, the fatty alcohol sulfonates or fatty alcohol sulfates are in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and have, as a rule, an alkyl radical having 8 to 22 carbon atoms, alkyl also including the alkyl moiety of acyl radicals, for example the sodium salt or calcium salt of lignosulfonic 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 the sulfonic acids of fatty alcohol/ethylene oxide addition products. The sulfonated benzimidazole derivatives preferably have 2 sulfonyl groups and a fatty acid radical having approximately 8-22 carbon 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. Suitable phosphates, for example salts of the phosphoric ester of a p-nonylphenol-(4-14) ethylene oxide adduct, or phospholipids, are also possible. Possible non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can have 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols. Other suitable non-ionic surfactants are the water-soluble polyethylene oxide addition products with polypropylene glycol, ethylene diaminopolypropylene glycol and alkyl polypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and have 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The abovementioned compounds conventionally have 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 addition products, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other substances which are suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate. The cationic surfactants are mainly quaternary ammonium salts which have, as N substituent, at least one alkyl radical having 8 to 22 carbon atoms and as further substituents lower, halogenated or unhalogenated alkyl, benzyl or lower hydroxyalkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide. The surfactants conventionally used in the art of formulation which can also be used in the compositions according to the invention are described, inter alia, in the following publications: - "Mc Cutcheon's Detergents and Emulsifiers Annual", Mc Publishing Corp., Glen Rock, New Jersey, 1988. - M. and J. Ash, "Encyclopedia of Surfactants", Vol. HE, Chemical Publishing Co., New York, 1980-1981. - Dr. Helmut Stache "Tensid-Taschenbuch" [Surfactants Guide], Carl Hanser Verlag, Munich/Vienna 1981. As a rule, the herbicidal preparations comprise as a rule 0.1 to 99 %, in particular 0.1 to 95 %, of active ingredient of the formula I, 1 to 99 % of a solid or liquid additive and 0 to 25 %, in particular 0.1 to 25 %, of a surfactant. While concentrated compositions are more preferred as commercially available goods, the end consumer uses, as a rule, dilute compositions. The compositions can also comprise further additives such as stabilizers, for example unepoxidized or epoxidized vegetable oils (epoxidized coconut oil, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders, tackifiers as well as fertilizers or other active ingredients for achieving specific effects. In particular, preferred formulations are composed as follows: (% = percent by weight) Emulsifiable concentrates: Active ingredient: 1 to 90 %, preferably 5 to 50 % Surface-active agent: 5 to 30 %, preferably 10 to 20 % Solvent: 15 to 94 %, preferably 70 to 85 % Dusts: Active ingredient: 0.1 to 50 %, preferably 0.1 to 1 % Solid carrier: 99.9 to 90 %, preferably 99.9 to 99 % Suspension concentrates: Active ingredient: 5 to 75 %, preferably 10 to 50 % Water: 94 to 24 %, preferably 88 to 30 % Surface active agent: 1 to 40 %, preferably 2 to 30 % Wettable powders: Active ingredient: 0.5 to 90 %, preferably 1 to 80 % Surface-active agent: 0.5 to 20 %, preferably 1 to 15 % Solid carrier: 5 to 95 %, preferably 15 to 90% Granules: Active ingredient: 0.1 to 30 %, preferably 0.1 to 15 % Solid carrier: 99.5 to 70 %, preferably 97 to 85 % As a rule, the active ingredients of the formula I are successfully employed at rates of application of 0.001 to 5 kg/ha, in particular 0.005 to 2 kg/ha. The dosage required for the desired effect can be determined by experiments. It depends on the nature of the effect, the development stage of the crop plant and of the weed as well as on the application (location, timing, method) and can vary within wide limits due to these parameters. The compounds of the formula I are distinguished by growth-inhibiting and herbicidal properties which make them outstandingly suitable for use in crops of useful plants, in particular in cereals, cotton, soya beans, oilseed rape, maize and rice. The examples which follow illustrate the invention in greater detail without imposing any limitation. The nomenclature used hereinbelow is based on the numbering showed below: 6 5 1 £ \ 4 2 3 Preparation Examples: Example HI: Preparation of 3,5-dichloro-l-pentylthiatriazine A solution of 13.4 g of A1C1 3 (0.1 mol) in 400 ml of THF is cooled to -70°C. A solution of pentylmagnesium bromide in ether is then added dropwise, and the mixture is allowed to come to 20°C and, after 15 minutes, is again cooled to -70°C. 20.5 g of trichlorothiatriazine in 50 ml of THF are subsequently added with stirring. The reaction mixture is kept for 2 hours at this temperature. It is then allowed to warm to room temperature and poured into 400 ml of ice- water. The organic phase is treated with dilute aqueous hydrochloric acid and then washed with water until neutral and dried using sodium sulfate. After filtration and concentration of the phase, an oily residue is obtained, and this is taken up in 200 ml of hexane. Insoluble components are removed and the solution which remains is cooled. White crystals of the compound given above form which have a melting point of 34°C after recrystallization.

Biological examples Example B 1 : Herbicidal action before emergence of the plants Monocotyledon and dicotyledon test plants are sown in standard soil in plastic pots. Immediately after sowing, the test substances are sprayed on (5001 of water/ha) in the form of an aqueous suspension (prepared with the formulation of Example FI) to give a dose of 2 kg of a.s./ha. The test plants are subsequently grown in a greenhouse under optimal conditions. After a test period of 3 weeks, the experiment is evaluated on the basis of a nine-step key (1 = complete damage, 9 = no action). Scores of 1 to 4 (in particular 1 to 3) mean a good to very good herbicidal action.
