In the substituents, which consist of several basic elements, the parts can be chosen freely within the given range of the definition. In accordance with the present invention, the novel 5-(pyrazol-1-yl)benzoic acid thiol esters of formula I are prepared by reacting a 5-(pyrazol-1-yl)benzoic acid of the formula II ##STR22## wherein R.sub.1, R.sub.2, X, Y and Z have the above given meaning, with a strong halogenating agent, to form the corresponding acid-halide of the formula III ##STR23## wherein R.sub.1, R.sub.2, X, Y and Z have the above given meaning, and Hal is a halogen atom, the acid halide is then converted in an inert organic solvent, in the presence of at least the equimolar amount of a base, with a mercaptan of the formula IV HS--A--Q (IV) wherein A and Q have the meaning given above to 5-(pyrazol-1-yl)benzoic acid-thiol ester of the formula I; or by treating the acid-halide of the formula III in an inert organic solvent, in the presence of a base with hydrogen sulfide, to form the 5-(pyrazol-1-yl)thiolbenzoic acid of the formula V ##STR24## wherein R.sub.1, R.sub.2, X, Y and Z have the meaning given above, and converting this acid in an inert organic solvent, in the presence of the equimolar amount of a base, with an alkylhalide of the formula VI Hal--A--Q (VI) wherein A and Q have the meaning given above and Hal is a halogen atom, preferably chlorine or bromine to a 5-(pyrazol-1-yl)-benzoic acidthiolester of the formula I. Another way to prepare the 5-(pyrazol-1-yl)benzoic acid-thiol esters of formula I consists in nitrating a 5-(pyrazol-1-yl)-benzoic acid of the formula VII ##STR25## wherein R.sub.1, X, Y and Z have the meaning given above, with a mixture of concentrated nitric acid and concentrated sulfuric acid, to obtain a 2-nitro-5-(pyrazol-1-yl)-benzoic acid of the formula VIII ##STR26## wherein R.sub.1, X, Y and Z have the meaning given above, and reducing this nitrobenzoic acid in a way known per se by means of hydrogen to the 2-amino-5-(pyrazol-1-yl)-benzoic acid of the formula IX ##STR27## wherein R.sub.1, X, Y and Z have the meaning given above, and diazotizing this aminobenzoic acid, in aqueous-acid medium, with sodium nitrate and a copper I-compound of the formula X Cu.sup.I --Hal (X) wherein Hal is chlorine, bormine or iodine, to the 5-(pyrazol-1benzoic acid derivative of the formula II, which is then treated with a strong halogenating agent, as in the previous method to form the benzoic acid-halide of the formula III, which is further converted either directly or via the 5-(pyrazol-1-yl)-thiolbenzoic acid of the formula V, to the 5-(pyrazol-1-yl)-benzoic acid-thiolester of the formula I. Suitable solvents or diluents for this reaction are higher boiling hydrocarbons, lower alkane acids and the esters thereof, higher boiling ketones and ethers. Examples of such solvents and diluents are toluene, xylene, acetic acid, ethyl acetate, isopropyl ether, tetrahydrofuran and methyl ethyl ketone. The reaction takes place at a temperature in the range from 0.degree. C to the boiling point of the reaction mixture. The reaction conditions in all described variants are similar. The compounds of formula I are usually successfully applied at concentrations of 0.05 to 4 kg/ha, in particular 0.1 to 1 kg/ha. When used at low rates of application, the compounds of formula I have good selective growth inhibiting and selective herbicidal properties which make them most suitable for use in crops of useful plants, preferably in cereals, cotton, maize and rice, especially however in soybeans. In some cases damage is also caused to weeds which have only been controlled up to now with total herbicides. The mode of action of these compounds is unusual. Many are translocatable, i.e. they are absorbed by the plant and transported to other parts of it where they then exert their action. Thus, for example, it is possible to damage perennial weeds to the roots by surface treatment Compared with other herbicides and growth regulators, the novel compounds of formula I are effective even when used at very low rates of application. The compounds of formula I have in addition pronounced plant growth inhibiting properties. The growth of both monocots and dicots is inhibited. Thus, for example, the compounds of formula I selectively inhibit the growth of leguminosae which are frequently planted as cover crops in tropical regions, so that, while soil erosion between cultivated plants is prevented, the cover crops cannot compete with the cultivated plants. Inhibition of the vegetative growth of many cultivated plants permits more plants to be sown in a crop area, so that a higher yield may be obtained per unit of area. A further mechanism of yield increase using growth inhibitors resides in the fact that nutrients are able increasingly to promote flower formation and fruiting, whereas vegetative growth is inhibited. The compounds of formula I can also be used for defoliating and desiccating crops of cotton and potatoes. By treating the crops at the moment of ripening, the harvesting of the cotton capsules or of the tubers is greatly facilitated when the leaves fall off and/or shrivel up or when the shrubs shrivel up. At higher rates of application of compounds of formula I, all tested plants are so severely damaged in their development that they die. The invention also relates to herbicidal and plant growth regulating compositions which contain a novel compound of formula I, and also to methods of controlling weeds pre- and postemergence and of inhibiting the growth of monocots and dicots, especially grasses, tropical cover crops and tobacco plant suckers. The compounds of formula I are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of formulation, and are therefore formulated in known manner e.g. to emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances. The formulations, i.e. the compositions, preparations or mixtures containing the compound (active ingredient) of formula I and, where appropriate, a solid or liquid adjuvant, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with extenders, e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants). Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether, ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils such as epoxidised coconut oil or soybean oil; or water. The solid carriers used e.g. for dusts and dispersible powders are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverised plant residues. Depending on the nature of the compound of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also be understood as comprising mixtures of surfactants. Suitable anionic surfactants can be both water-soluble soaps and watersoluble synthetic surface-active compounds. Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C.sub.10 -C.sub.22), e.g. the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tallow oil. Mention may also be made of fatty acid methyltaurin salts. More frequently, however, so-called synthetic surfactants are used. especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstitued or substituted ammonium salts and contain a Cs-Czzalkyl radical which also includes the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of lignosulfonic acid, of dodecylsulfate or of a mixture of fatty alcohol sulfates obtained from natural fatty acids. These compounds also comprise the salts of sulfuric acid esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a naphthalenesulfonic acid/formaldehyde condensation product. Also suitable are corresponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of ethylene oxide, or phospholipids. Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, or saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 10 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. Further suitable non-ionic surfactants are the water-soluble adducts of polyethylene oxide with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Representative examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate, are also suitable non-ionic surfactants. Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least one C.sub.8 -C.sub.22 alkyl radical and, as further substituents, unsubstituted or halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide. The surfactants customarily employed in the art of formulation are described e.g. in the following publications: "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., 1981; H. Stache, "Tensid-Taschenbuch" (Handbook of Surfactants), C. Hanser Verlag, Munich & Vienna, 1981. The herbicidal preparations usually contain 0.1 to 95 %, preferably 0.1 to 80 %, of a compound of formula I, 1 to 99.9 % of a solid or liquid adjuvant, and 0 to 25 %, preferably 0.1 to 25 %, of a surfactant. Preferred formulations are composed in particular of the following constituents (% =percentage by weight): ______________________________________Emulsifiable concentratescompound of formula I: 1 to 20%, preferably 5 to 10%surfactant: 5 to 30%, preferably 10 to 20%liquid carrier: 50 to 94%, preferably 70 to 85%Dustscompound of formula I: 0.1 to 10%, preferably 0.1 to 1%solid carrier: 99.9 to 90%, preferably 99.9 to 99%Suspension concentratescompound of formula I: 5 to 75%, preferably 10 to 50%water: 94 to 25%, preferably 90 to 30%surfactant: 1 to 40%, preferably 2 to 30%Wettable powderscompound of formla I: 0.5 to 90%, preferably 1 to 80%surfactant: 0.5 to 20%, preferably 1 to 15%solid carrier: 5 to 95%, preferably 15 to 90%Granulatescompound of formula I: 0.5 to 30%, preferably 3 to 15%solid carrier: 99.5 to 70%, preferably 97 to 85%.______________________________________ Whereas commercial products will be preferably formulated as concentrates, the end user will normally employ dilute formulations. The formulations can be diluted to a concentration as low as 0.001 % of active ingredient. The rates of application are usually from 0.005 to 5 kg a.i./ha. The compositions may also contain further ingredients such as stabilisers, antifoams, viscosity regulators, binders, tackifiers, as well as fertilisers and other compounds for obtaining special effects.

After the non-adsorptive vermiculite has been saturated with an aqueous emulsion in deionised water which contains the test compound in a concentration of 70.8 ppm, seeds of the following plants are sown on the surface: Nasturtium officinalis, Agrostis tenuis, Stellaria media and Digitaria sanguinalis. The pots are then kept in a climatic chamber at 20.degree. C., an illumination of about 20 klux and a relative humidity of 70%. During the germinating phase of 4 to 6 days, the pots are covered with lightpermeable material and watered with deionised water to increase the local humidity. After the 5th day, 0.5% of a commercial liquid fertiliser (Greenzit.TM.) is added to the water. The test is evaluated 12 days after sowing and the action on the test plants is assessed. The tested compounds of Tables 1 to 4 exhibit good to very good herbicidal activity. EXAMPLE 7 Herbicidal action in rice (paddy rice) Rice and the weeds Scirpus sp. and Monocharia vag., which occur in water, are sown in plastic beakers (surface: 60 cm.sup.2 ; volume: 500 ml). After sowing, the beakprs are filled with water up to the surface of the soil. 3 days after sowing, the water level is increased to slightly above the soil surface (3-5 mm). Application is effected 3 days after sowing by spraying the beakers with an aqueous emulsion of the test compounds. The rate of application corresponds to a concentration of 0.5 kg of active ingredient per hectare (concentration of the spray mixture =550 1/ha). The beakers are then kept in the greenhouse under optimum growth conditions for rice weeds, i.e. at 25 .degree.-30.degree. C. and at high humidity. The evaluation of the tests takes place 3 weeks after application. The state of the plants is assessed in accordance with the rating indicated above. The tested compounds of tables 1 to 4 showed good herbicidal action on the weeds while being tolerant towards the rice plants. EXAMPLE 8 Desiccation and defoliation action Cotton plants of the Deltapine variety are reared in earthen-ware pots in a greenhouse. After the capsules have formed, the plants are sprayed with an aqueous formulation of compound No. 1 at rates of application corresponding to 1.2, 0.6 and 0.3 kg/ha in field application. Untreated plants act as controls. Evaluation of the test is made 3, 7 and 14 days after application of the active ingredient by determining the degree of defoliation (percentage of fallen leaves) and of desiccation (drying out of the leaves remaining on the plant). In this test, plants treated with compounds of Tables 1 to 4 at rates of application of 0.6 and 1.2 kg/ha are left after 7 days with only a few. dried out leaves (>80 % defoliation and dessication). EXAMPLE 9 Growth inhibition of grasses and clover A mixture of grasses Poa, Festuca, Lo Bromus, Cynosurus and of clover (Trifolium pratense and repens) are sown in 15 cm plastic pots filled with sterile garden soil and reared in a greenhouse at a day temperature of 21.degree. C. and a night temperature of 17.degree. C. Lighting was 13.5 hours daily at at least 7000 Lux. After emergence the plants were cut back each week to 6 cm hight. About 42 days after sowing and one day after the last cut, the plants are sprayed with an aqueous mixture of a compound of Tables 1 to 4 in an application between 0.3 and 3 kg/ha, which was prepared by dilution of a 25% wettable powder at an amount of water corresponding to 500 1/ha. The test was evaluated 3 weeks after the treatment. The hight of the regrowth was measured and compared to the average regrowth of not treated control plants. The compounds of Tables 1 to 4 that were tested reduced the regrowth by 10 to 80 %.
