Pyrazole-3-chrboxim3.des are known from the liter~~ure for the following applications:

Fungicid~ EP-~ 206 523 - Indian: J: Chem. 13, (1975] 655 In addition, DE~A-33 32 633yrlescribea pyrazole-3 carboxamides which are substituted in the 5-posi~ian of the heterocyclic ring by vitro, trifluoromethyl, halogen or C1-C~-alkoxy, as pharmaceuticals. ' - 5 - O.z. 0050/41113 However, a herbicidal action of substances of this type was not found.
It is an object of the present invention to provide novel herbicidally active substances.
We have found that this ob jeot is achieved by the pyrazole-3-carboxamides I defined at the outset.
We have also found that the pyrazole-3-carbox-amides I and the pyrazole-3-carboxamides Ia are suitable for controlling undesired plant growth.
The pyrazole-3-carboxamides I according to the invention can be prepared by various processes, for example by the following:
1. A process for the preparation of a compound I in which RS is COZR° and R' is C1-C4-alkyl R~ I
(R° - C1-Ca-alkyl) ~ R
These pyrazole-3-carboxamides L are obtained by reacting a dialkyl pyrazole-3,4-dicaxboxylate of the formula II in a conventional manner in an inert organic solvent with an amine of the formula IIT

R' in the formulae II amd I is C1-C4-alkyl, such as methyl, ethyl, propyl, 1-mathylethyl, butyl, 1-methyl-propyl, 2-metraylpropyl or l,l-dimethylethyl, preferably methyl, ethyl or 1-methylethyl.
The reaction is generally carried out at from 0 to 100°C, preferably from 50 to ~0°C, in an inert organic solvent.

The process is particularly preferably carried out in the alcohol corresponding to the ester component.
The concentration of the starting materials in the solvent is generally from 0.1 to S.O mo1/1, prefer-ably from 0.2 to 2.0 mol/1.
The molar ratio between II and III is generally from 1:2.5 to 1:1, preferably from 1:1.5 to 1:1, A particularly preferred process involves the use of a diester II and an amine III in the ratio 1:1 in the absence of solvents at from 50 to 80°C.
The pyrazoledicarboxy~.ates II required as start-ing materials fax this process are known from the litera-ture or can be pr~pared by methods known from the litera-ture (cf. J. Heterocyclic Chem. 25, (1988) 1293; J. Am.

The annines V' required are either commercially available or can be prepared by conventional processes.
A particularly preferred process for the prepara-tion of the pyrazole-3-carbox~mides bf the formula I
comprises converting a pyrazole-3,4-dicarboxylate of the formula IIa into a monocarboxylic acid ITb using an aqueous base: The comp~und IIb can be converted into the desired amide via the acyl chloride intermediate using an amine of the formula III:

66 O.Z. 0050/41113 Suitable salts of compounds of the formula Ia are agriculturally useful salts, for example alkali metal salts, such as potassium and sodium salts, alkaline earth metal salts, such as calcium, magnesium and barium salts, manganese, copper, zinc or iron salts, e.g., ammonium salts, tetraalkyl-ammonium salts, benzyltrialkylammonium salts, trialkylsulfonium salts and trialkylsulfoxonium salts.
The herbicidal compounds I, or agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), disper-lions, emulsions, oil dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.
For the preparation of solutions, emulsions, pastes and oil dispersions to be sprayed direct, mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, further coal-tar oils, and oils of vege-'table or animal origin, aliphatic, cyclic and aromatic hydrocarbons such as toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphtha-lenes and their derivatives, methanol, ethanol, propanol, butanol, cyclo-hexanol, cyclohexanone, chlorobenzene, isophorone, etc., and strongly polar solvents such as N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, water, etc. are suitable.
Aqueous formulations may be prepared from emulsion concentrates, pastes, oil dispersions, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes and oil dispersions the ingredients as such or dissolved in an oil or solvent may be homogenized in water by means of wetting or dispersing agents, adherents or emulsifiers. Concen-trates which are suitable for dilution with water may be prepared from active ingredient, wetting agent; adherent, emulsifying or dispersing agent and possibly solvent or oil.

BASF Aktiengesellschaft 69 O.Z. 0050/41113 When the active ingredients are used as herbicides, the application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stage, and are from 0.001 to 5, preferably 0.01 to 2, kg of active ingredient per hectare.
To increase the spectrum of action and to achieve synergistic effects, the compounds I may be mixed with each other, or mixed and applied together with numerous representatives of other herbicidal or growth-regulating active ingredient groups. Examples of suitable components are diazines, 4H-3,1-benzoxazine derivatives, benzothiadiazinones, 2,6-dinitroanilines, N-phenylcarbamates, thiolcarbamates, halocarboxylic acids, triazines, amides, ureas, Biphenyl ethers, triazinones, uracils, benzofuran deriva-tives, cyclohexane-1,3-dione derivatives, quinolinecarboxylic acids, (het-ero)-aryloxyphenoxypropionic acids and salts, esters, amides thereof, etc.
It may also be useful to apply the herbicidal compounds Ia, either alone or in combination with other herbicides, in admixture with other crop protection agents, e.g., agents for combating pests or phytopathogenic fungi or bacteria. The compounds may also be mixed with solutions of mineral salts used to remedy nutritional or trace element deficiencies.
Non-phytotoxic oils and oil concentrates may also be added.

I-- W .- r,.~ .~.-...r..~ .-r 76 O.Z. 0050/41113 Use examples The herbicidal action of the pyrazole-3-carboxamides of the formula Ia is demonstrated in greenhouse experiments:
The vessels employed were plastic flowerpots having a volume of 300 cm3 and filled with a sandy loam containing about 3.O~o humus. The seeds of the test plants were sown separately, according to species.
For the preemergence treatment, the formulated active ingredients were applied to the surface of the soil immediately after the seeds had been sown. The compounds were emulsified or suspended in water as vehicle, and sprayed through finely distributing nozzles. After the agents had been applied, the vessels were lightly sprinkler-irrigated to induce germin-ation and growth. Transparent plastic covers were then placed on the vessels until the plants had taken root. The cover ensured uniform germin-ation of the plants, insofar as this was not impaired by the active ingredients.
For the postemergence treatment, the plants were grown, depending on growth form, to a height of 3 to 15 cm before being treated with the com-polands, suspended or emulsified in water. The application rate for post-emergence treatment was 1.0 kg/ha.
The pots were set up in the greenhouse, heat-loving species at 20 to 35°C, and species from moderate climates at 10 to 25°C. The experiments were run for from 2 to 4 weeks. During this period the plants were tended and their reactions to the various treatments assessed. The assessment scats was 0 to 100, 100 denoting nonemergence or complete destruction of at least the visible plant parts, and 0 denoting no damage or normal growth.
The plants used in the experiments were Chenopodium album, Sinapis albs and Solanum nigrum.
Active ingredients nos. 1.014 and 1.022, applied postemergence at a rate of 1.0 kg/ha, provided excellent control of unwanted broadleaved plants.

66 O.Z. 0050/41113 Suitable salts of compounds of the formula Ia are agriculturally useful salts, for example alkali metal salts, such as potassium and sodium salts, alkaline earth metal salts, such as calcium, magnesium and barium salts, manganese, copper, zinc or iron salts, e.g., ammonium salts, tetraalkyl-ammonium salts, benzyltrialkylammonium salts, trialkylsulfonium salts and trialkylsulfoxonium salts.
The herbicidal compounds I, or agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), disper-lions, emulsions, oil dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.
For the preparation of solutions, emulsions, pastes and oil dispersions to be sprayed direct, mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, further coal-tar oils, and oils of vege-'table or animal origin, aliphatic, cyclic and aromatic hydrocarbons such as toluene, xylene, paraffin, tetrahydronaphthalene, alkylated naphtha-lenes and their derivatives, methanol, ethanol, propanol, butanol, cyclo-hexanol, cyclohexanone, chlorobenzene, isophorone, etc., and strongly polar solvents such as N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, water, etc. are suitable.
Aqueous formulations may be prepared from emulsion concentrates, pastes, oil dispersions, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes and oil dispersions the ingredients as such or dissolved in an oil or solvent may be homogenized in water by means of wetting or dispersing agents, adherents or emulsifiers. Concen-trates which are suitable for dilution with water may be prepared from active ingredient, wetting agent; adherent, emulsifying or dispersing agent and possibly solvent or oil.
Examples of surfactants are: alkali metal, alkaline earth metal and ammonium salts of aromatic sulfonic acids, e.g., ligninsulfonic acid, phenoisulfonic acid, naphthalenesulfonic acid and dibutylnaphthalene-sulfonic acid, and of fatty acids, alkyl and alkylaryl sulfonates, and alkyl, lauryl ether and fatty alcohol sulfates, and salts of sulfated hexadecanols, heptadecanols, and octadecanols, salts of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalenesulfonic acids with phenol and formaldehyde, s r~ m a~.'.~~

Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients with a solid carrier.
Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. Examples of solid carriers are mineral earths such as silicic acids, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain meals, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.
The formulations contain from 0.1 to 95, and preferably 0.5 to 90, ~o by weight of active ingredient. The active ingredients are used in a purity of 90 to 100, and preferably 95 to 100, fo (according to the NMR spectrum).
Compounds I according to the invention may be formulated as follows:
I. 90 parts by weight of compound no. 1.014 is mixed with 10 parts by weight of N-methyl-alpha-pyrrolidone. A mixture is obtained which is suitable for application in the form of very fine drops.
II. 20 parts by weight of compound no. 1.022 is dissolved in a mixture consisting of 80 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 moles of ethylene oxide and l mole of oleic acid-N-monoethanolamide, 5 parts by weight of the calcium salt of dodecylbenzene-sulfonic acid, and 5 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil.

BASF Aktiengesellschaft 69 O.Z. 0050/41113 When the active ingredients are used as herbicides, the application rates depend on the objective to be achieved, the time of the year, the plants to be combated and their growth stage, and are from 0.001 to 5, preferably 0.01 to 2, kg of active ingredient per hectare.
To increase the spectrum of action and to achieve synergistic effects, the compounds I may be mixed with each other, or mixed and applied together with numerous representatives of other herbicidal or growth-regulating active ingredient groups. Examples of suitable components are diazines, 4H-3,1-benzoxazine derivatives, benzothiadiazinones, 2,6-dinitroanilines, N-phenylcarbamates, thiolcarbamates, halocarboxylic acids, triazines, amides, ureas, Biphenyl ethers, triazinones, uracils, benzofuran deriva-tives, cyclohexane-1,3-dione derivatives, quinolinecarboxylic acids, (het-ero)-aryloxyphenoxypropionic acids and salts, esters, amides thereof, etc.
It may also be useful to apply the herbicidal compounds Ia, either alone or in combination with other herbicides, in admixture with other crop protection agents, e.g., agents for combating pests or phytopathogenic fungi or bacteria. The compounds may also be mixed with solutions of mineral salts used to remedy nutritional or trace element deficiencies.
Non-phytotoxic oils and oil concentrates may also be added.

I-- W .- r,.~ .~.-...r..~ .-r 76 O.Z. 0050/41113 Use examples The herbicidal action of the pyrazole-3-carboxamides of the formula Ia is demonstrated in greenhouse experiments:
The vessels employed were plastic flowerpots having a volume of 300 cm3 and filled with a sandy loam containing about 3.O~o humus. The seeds of the test plants were sown separately, according to species.
For the preemergence treatment, the formulated active ingredients were applied to the surface of the soil immediately after the seeds had been sown. The compounds were emulsified or suspended in water as vehicle, and sprayed through finely distributing nozzles. After the agents had been applied, the vessels were lightly sprinkler-irrigated to induce germin-ation and growth. Transparent plastic covers were then placed on the vessels until the plants had taken root. The cover ensured uniform germin-ation of the plants, insofar as this was not impaired by the active ingredients.
For the postemergence treatment, the plants were grown, depending on growth form, to a height of 3 to 15 cm before being treated with the com-polands, suspended or emulsified in water. The application rate for post-emergence treatment was 1.0 kg/ha.
The pots were set up in the greenhouse, heat-loving species at 20 to 35°C, and species from moderate climates at 10 to 25°C. The experiments were run for from 2 to 4 weeks. During this period the plants were tended and their reactions to the various treatments assessed. The assessment scats was 0 to 100, 100 denoting nonemergence or complete destruction of at least the visible plant parts, and 0 denoting no damage or normal growth.
The plants used in the experiments were Chenopodium album, Sinapis albs and Solanum nigrum.
Active ingredients nos. 1.014 and 1.022, applied postemergence at a rate of 1.0 kg/ha, provided excellent control of unwanted broadleaved plants.
