Description

DESCRIPTION
Sulfur-substituted phenylsulfonylureas; processes for their preparation and their use as herbicides and plant growth regulators.
The invention relates to the technical field of herbicides and plant growth regulators, in particular herbicides for selective control of broad-leaved weeds and graminaceous weeds in crops of useful plants.
It is known that phenylsulfonylureas which have heterocyclic substituents and carry an amino or a functionalized amino group or a sulfur substituent on the phenyl ring have herbicidal and plant growth regulating properties (EP-A-1515; EP-A-7687; EP-A-30138; U.S. Pat. No. 4,892,946; U.S. Pat. No. 4,981,509, U.S. Pat. No. 4,664,695; U.S. Pat. No. 4,632,695, EP-A-116518; EP-A-23141 (=U.S. Pat. No. 4,310,346); U.S. Pat. No. 4,369,058; EP-A-84020; EP-A-192489; DE 42 36 902 Al).
Surprisingly, it has now been found that certain phenylsulfonylureas with heterocyclic substituents are particularly suitable as herbicides and plant growth regulators.

In formula (I) and all the formulae below, the alkyl, alkoxy, haloalkyl, haloalkoxy, alkylamino and alkylthio radicals and the corresponding unsaturated and/or substituted radicals can in each case be straight-chain or branched in the carbon skeleton. Unless specifically stated, the lower carbon skeletons, for example having 1 to 6 carbon atoms, or in the case of unsaturated groups having 2 to 6 carbon atoms, are preferred for these radicals. Alkyl radicals, including in the composite meanings, such as alkoxy, haloalkyl and the like, are, for example, methyl, ethyl, n- or i-propyl, n-, i-, t- or 2-butyl, pentyl radicals, hexyl radicals, such as n-hexyl, i-hexyl and 1,3-dimethylbutyl, or heptyl radicals, such as n-heptyl, 1-methylhexyl and 1,4-dimethylpentyl; alkenyl and alkynyl radicals have the meaning of the possible unsaturated radicals corresponding to the alkyl radicals; alkenyl is, for example, allyl, 1-methyl-prop-2-en-1-yl, 2-methyl-prop-2-en-1-yl, but-2-en-1-yl, but-3-en-1-yl, 1-methyl-but-3-en-1-yl and 1-methyl-but-2-en-1-yl; and alkynyl is, for example, propargyl, but-2-yn-1-yl, yl, but-3-yn-1-yl and 1-methyl-but-3-yn-1-yl.

The heterocyclic radical can be, for example, a heteroaromatic radical or ring (heteroaryl), such as, for example, a mono-, bi- or polycyclic aromatic system in which at least 1 ring contains one or more hetero atoms, for example pyridyl, pyrimidinyl, pyridazinyl, pyrazinyl, thienyl, thiazolyl, oxazolyl, furyl, pyrrolyl, pyrazolyl and imidazolyl, or is a partly hydrogenated radical, such as oxiranyl, pyrrolidyl, piperidyl, piperazinyl, dioxolanyl, morpholinyl or tetrahydrofuryl. Possible substituents for a substituted heterocyclic radical are the substituents mentioned below, and in addition also oxo. The oxo groups can also occur on the hetero ring atoms which can exist in different oxidation levels, for example in the case of N and S.
Substituted radicals, such as substituted hydrocarbon radicals, for example substituted alkyl, alkenyl, alkynyl, aryl, phenyl and benzyl, or substituted heterocyclyl or heteroaryl, are, for example, a substituted radical derived from the unsubstituted parent substance, the substituents being, for example, one or more, preferably 1, 2 or 3, radicals from the group consisting of halogen, alkoxy, haloalkoxy, alkylthio, hydroxyl, amino, nitro, carboxy, cyano, azido, alkoxycarbonyl, alkylcarbonyl, formyl, carbamoyl, mono- and dialkylaminocarbonyl, substituted amino, such as acylamino and mono- and dialkylamino, and alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl and, in the case of cyclic radicals, also alkyl and haloalkyl, as well as unsaturated aliphatic radicals corresponding to the saturated hydrocarbon-containing radicals mentioned, such as alkenyl, alkynyl, alkenyloxy, alkynyloxy and the like.

This reaction is carried out in bulk or in inert solvents, such as, for example, methylene chloride, sulfolane or acetonitrile or in a solvent mixture of inert components. The subsequent reaction with ammonia or tert-butylamine leads to the sulfonamides of the formula (XI) where R.dbd.H or tert-butyl. These compounds can be converted with mercaptans in solvents, such as, for example, dimethylformamide, N,N-dimethylacetamide or N-methylpyrrolidinone, in the presence of suitable bases, such as, for example, sodium carbonate or potassium carbonate, into the corresponding mercaptans of the formula (XII) (n=0). By the choice of suitable oxidizing agents (for example potassium peroxomonosulfate, .RTM.Oxone) and reaction conditions, the corresponding compounds of the formula (XII) where n=1 and 2 can be prepared analogously to known methods.
After the reduction of the nitro group from the compounds of the formula (XII), for example with iron in an acetic acid medium or other customary methods (for example hydrogenation with Pd--C/hydrogen), the aniline of the formula (XIII) is obtained.
This compound is formylated by methods analogous to those known from the literature, for example with formic acid and acetic anhydride, to give the compounds of the formula (IIa) or (XIV). In the case where R=tert-butyl, the tert-butyl group is split off from the aromatics of the formula (XIV) by reaction with strong acids to give the sulfonamides of the formula (IIa). Possible strong acids are, for example, mineral acid, such as, for example, H.sub.2 SO.sub.4 or HCl, or strong organic acids, such as, for example, CF.sub.3 COOH.
Equation 1: Synthesis of the sulfonamides (IIa) ##STR13##
Derivatization of the compounds (IIa) on the formyl group to give other groups such as occur in formula (I) can be carried out at this stage analogously to known processes.
The carbamates of the formula (III) required for the reaction of the compounds (II) by variant a) are known from the literature or can be prepared analogously to known processes (cf. EP-A-70804 or U.S. Pat. No. 4,480,101).
For compounds of the formula (I) where n=2 and R.sup.1 =the nitrogen or oxygen function, another synthesis route is recommended as an alternative to Equation 1. Compounds of the formula (XII) where n=0 and, for example, R.sup.1 =benzyl are converted into the corresponding sulfochlorides of the formula (XV) by oxidative chlorination with chlorine or hypochlorite. The nitroaromatics of the formula (XII) (n=2, R.sup.1 .dbd.O--R', R.sup.1 .dbd.NR"R"') are obtainable by reaction of alcoholates, phenolates or a with the sulfochloride of the formula (XV). The further synthesis sequence to give the corresponding sulfonylureas of the formula (I) (n=2, R.sup.1 .dbd.OR', R.sup.1 .dbd.NR"R"') can be carried out analogously to the transformation of compound (XII).fwdarw.compound (I) described above (cf. Equation 2). ##STR14## Alternatively, the sulfonylureas of the formula (I) where R*.dbd.CHO can be prepared by reaction of a formylating reagent with the sulfonylurea of the formula (VII). ##STR15## For this, the compounds of the formula (VII) are initially introduced into the reaction vessel at temperatures between -10.degree. C. and 70.degree. C., preferably 0.degree. to 40.degree. C., in an inert solvent, such as, for example, methylene chloride, chloroform, dimethylformamide or N,N-dimethylacetamide, and a suitable formylating agent, for example the mixed anhydride of formic and acetic acid, is added. Compounds of the formula (VII) are known from the literature (EP-A-23141, U.S. Pat. No. 4,369,058) or can be prepared in a manner analogous to the processes described therein.
The reactions of sulfonamides of the formula (II) with chloroformic acid aryl esters (VI) and heterocyclic amines of the formula (V) likewise lead to the compounds of the formula (I). From the sulfonamides of the formula (IIa) and chloroformic acid aryl esters (for example Ar=phenyl), the corresponding sulfonylcarbamates of the formula (XVI) ##STR16## are first formed in the presence of a suitable base, such as, for example, triethylamine or potassium carbonate. These sulfonylcarbamates of the formula (XVI) can then be reacted with heterocyclic amines (V) to give the sulfonylureas (I) (cf. U.S. Pat. No. 4,994,571).
The reaction of the sulfochlorides (IV) with the amino-heterocyclic compounds of the formula (V) and cyanates, such as sodium cyanate and potassium cyanate, is carried out, for example, in aprotic solvents, such as, for example, acetonitrile, sulfolane, N-methylpyrrolidone, dimethylformamide, pyridine, picoline or lutidine, or a mixture of the solvents mentioned, at temperatures between -10.degree. C. and 100.degree. C., preferably between 0.degree. and 50.degree. C. (cf. U.S. Pat. No. 5,157,119).
The (thio)isocyanates of the formula (VIII) are obtainable by processes known from the literature (EP-A-232067, EP-A-166516). The reaction of the (thio)isocyanates (VIII) with compounds (II) is carried out at -10.degree. C. to 100.degree. C., preferably 20.degree. to 100.degree. C., in an inert aprotic solvent, such as, for example, acetone or acetonitrile, in the presence of a suitable base, for example N(C.sub.2 H.sub.5).sub.3 or K.sub.2 CO.sub.3.
The salts of the compounds of the formula (I) are preferably prepared in inert polar solvents, such as, for example, water, methanol, acetone, methylene chloride or tetrahydrofuran, and in individual cases also in non-polar solvents, such as toluene or heptane, at temperatures from 0.degree. to 100.degree. C. Suitable bases for preparation of the salts according to the invention are, for example, alkali metal carbonates, such as sodium carbonate, alkali metal and alkaline earth metal hydroxides, for example NaOH, KOH or Ca(OH).sub.2, ammonia or a suitable amine base from the group consisting of primary, secondary and tertiary amines, such as triethylamine or ethanolamine. Suitable acids for the salt formation are, for example, HCl, HBr, H.sub.2 SO.sub.4 or HNO.sub.3.
The intermediates of the formulae (II), (IV), (XIV) and (XVI) are novel and the present invention likewise relates to these; together, they correspond to compounds of the formula (XVII) ##STR17## in which U* is NH.sub.2, Cl or mono- or disubstituted amino, such as alkylamino, in particular t-butylamino, or aryloxycarbonylamino, and R*, R.sup.1, R.sup.2, n and m are defined as in formula (I).
The "inert solvents" mentioned in the above process variants mean in each case solvents which are inert under the particular reaction conditions but which do not have to be inert under any desired reaction conditions.
The term "compounds of the formula (I) according to the invention" below summarily also relates to salts of the compounds of the formula (I).
The compounds of the formula (I) according to the invention have an excellent herbicidal activity against a broad spectrum of economically important mono- and dicotyledon harmful plants. Perennial weeds which are difficult to control and shoot from rhizomes, rootstock or other permanent organisms are also readily attacked by the active compounds. It is irrelevant here whether the substances are applied prior to sowing, pre-emergence or post-emergence.
Some representatives of monocotyledon and dicotyledon weed flora which can be controlled by the compounds according to the invention may be mentioned specifically by way of example, without a limitation to certain species being intended by the naming of these.
On the part of the monocotyledon species of weeds, for example, Avena, Lolium, Alopecurus, Phalaris, Echinochloa, Digitaria, Setaria and Cyperus species from the annual group and on the part of the perennial species, Agropyron, Cynodon, Imperata and Sorghum and also perennial Cyperus species are readily attacked.
In the case of dicotyledon species of weeds, the action spectrum extends to species such as, for example, Galium, Viola, Veronica, Lamium, Stellaria, Amaranthus, Sinapis, Ipomoea, Matricaria, Abutilon and Sida on the annual side, and Convolvulus, Cirsium, Rumex and Artemisia in the case of perennial weeds.
Weeds which occur under the specific growing conditions in rice, such as, for example, Sagittaria, Alisma, Eleocharis, Scirpus and Cyperus, are likewise controlled outstandingly by the active compounds according to the invention.
If the compounds according to the invention are applied to the soil surface before germination, either the emergence of the weed seedlings is prevented completely or the weeds grow to the cotyledon stage but then stop their growth and finally die completely at the end of three to four weeks.
If the active compounds are applied to the green parts of plants by the post-emergence method, a drastic stop in growth likewise occurs very rapidly after the treatment and the weed plants remain in the growth stage existing at the time of application or die completely after a certain period of time, so that weed competition, which is harmful to the crop plants, is eliminated very early and lastingly in this manner.
Although the compounds according to the invention have an excellent herbicidal activity against monocotyledon and dicotyledon weeds, crop plants of economically important crops, such as, for example, wheat, barley, rye, rice, maize, sugar beet, cotton and soya, are harmed only insignificantly or not at all. For these reasons, the present compounds are particularly suitable for selective control of undesirable plant growth in agricultural crop plantations.
The substances according to the invention furthermore have outstanding growth regulatory properties in crop plants. They intervene in the endogenous metabolism of the plants in a regulating manner and can therefore be employed for controlled influencing of plant contents and for facilitating harvesting, such as, for example, by inducing desiccation and stunted growth. They are furthermore also suitable for general control and inhibition of undesirable vegetative growth without killing the plants at the same time. Inhibition of vegetative growth plays a major role in many monocotyledon and dicotyledon crops, since lodging can be reduced or prevented completely by this means.
The compounds according to the invention can be used in the customary formulations in the form of wettable powders, emulsifiable concentrates, sprayable solutions, dusting powders or granules. The invention therefore also relates to herbicidal and plant growth-regulating compositions which comprise the compounds of the formula (I).
The compounds of the formula (I) can be formulated in various ways, depending on the biological and/or chemico-physical parameters which exist. Suitable formulation possibilities are, for example: wettable powders (WP), water-soluble powders (SP), water-soluble concentrates, emulsifiable concentrates (EC), emulsions (EW), such as oil-in-water and water-in-oil emulsions, sprayable solutions, suspension concentrates (SC), oil- or water-based dispersions, oil-miscible solutions, capsule suspensions (CS), dusting powders (DP), seed dressings, granules for application by scattering and to the soil, granules (GR) in the form of microgranules, sprayed granules, absorption granules and adsorption granules, water-dispersible granules (WG), water-soluble granules (SG), ULV formulations, microcapsules and waxes.
These individual types of formulation are known in principle and are described, for example, in: Winnacker-Kuchler, "Chemische Technologie" �Chemical technology!, Volume 7, C. Hauser Verlag Munich, 4th edition 1986, Wade van Valkenburg, "Pesticide Formulations", Marcel Dekker, N.Y., 1973; K. Martens, "Spray Drying", Handbook, 3rd edition 1979, G. Goodwin Ltd. London.
The necessary formulating auxiliaries, such as inert materials, surfactants, solvents and further additives, are likewise known and are described, for example, in: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd edition, Darland Books, Caldwell, N.J., H.v. Olphen, "Introduction to Clay Colloid Chemistry"; 2nd edition, J. Wiley & Sons, N.Y.; C. Marsden, "Solvents Guide"; 2nd edition, Interscience, N.Y. 1963; McCutcheon's "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood, N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflachenaktive Athylenoxidaddukte" �Surface-active ethylene oxide adducts!, Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Kuchler, "Chemische Technologie" �Chemical technology!, Volume 7, C. Hauser Verlag Munich, 4th edition 1986.
Combinations with other substances having a pesticidal action, such as, for example, insecticides, acaricides, herbicides and fungicides, and with safeners, fertilizers and/or growth regulators, can be prepared on the basis of these formulations, for example in the form of a ready-to-use formulation or as a tank mix.
Wettable powders are preparations which are uniformly dispersible in water and which, alongside the active compound, and in addition to a diluent or inert substance, also comprise surfactants of an ionic and/or nonionic nature (wetting agents, dispersing agents), for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, polyoxyethylated fatty amines, fatty alcohol polyglycol ether-sulfates, alkanesulfonates, alkylbenzenesulfonates, sodium ligninsulfonate, sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, sodium dibutylnaphthalene-sulfonate or sodium oleylmethyltauride. To prepare the wettable powders, for example, the herbicidal active compounds are finely ground in customary apparatuses, such as hammer mills, blast mills and air jet mills, and are mixed with the formulating auxiliaries at the same time or subsequently.
Emulsifiable concentrates are prepared by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or also higher-boiling aromatics or hydrocarbons or mixtures of organic solvents, with the addition of one or more surfactants of an ionic and/or nonionic nature (emulsifiers). Emulsifiers which can be used are, for example: calcium alkylarylsulfonates, such as Ca dodecylbenzenesulfonate, or nonionic emulsifiers, such as fatty acid polyglycol esters, alkylarylpolyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensation products, alkyl polyethers, sorbitan esters, such as, for example, sorbitan fatty acid esters, or polyoxyethylene sorbitan esters, such as, for example, polyoxyethylene sorbitan fatty acid esters.
Dusting powders are obtained by grinding the active compound with finely divided solid substances, for example talc, naturally occurring clays, such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.
Suspension concentrates can be water- or oil-based. They can be prepared, for example, by wet grinding by means of commercially available bead mills and, if appropriate, with the addition of surfactants, such as are already listed above, for example, for the other types of formulation.
Emulsions, for example oil-in-water emulsions (EW), can be prepared, for example, by means of stirrers, colloid mills and/or static mixers using aqueous organic solvents and if appropriate surfactants, such as are already listed above, for example, for the other types of formulation.
Granules can be prepared either by spraying the active compound onto granular inert material capable of adsorption or by applying active compound concentrates to the surface of carrier substances, such as sand, kaolinites or granular inert material, by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or mineral oils. Suitable active compounds can also be granulated in the manner customary for the preparation of fertilizer granules--if desired as a mixture with fertilizers.
Water-dispersible granules are as a rule prepared by customary processes, such as spray drying, fluidized bed granulation, disk granulation, mixing with high-speed mixers and extrusion, without a solid inert material. For the preparation of disk, fluidized bed, extruder and sprayed granules cf., for example, processes in "Spray-drying Handbook" 3rd edition 1979. G. Goodwin Ltd., London; J. E. Browning, "Agglomeration", Chemical and Engineering 1967, pages 147 et seq.; "Perry's Chemical Engineer's Handbook", 5th edition, McGraw-Hill, New York 1973, pages 8-57.
For further details on the formulation of plant protection agents cf., for example, G. C. Klingman, "Weed Control as a Science", John Wiley and Sons, Inc., New York, 1961, pages 81-96 and J. D. Freyer, S. A. Evans, "Weed Control Handbook", 5th edition, Blackwell Scientific Publications, Oxford, 1968, pages 101-103.
The agrochemical formulations as a rule comprise 0.1 to 99% by weight, in particular 0.1 to 95% by weight, of active compound of the formula (I). In wettable powders, the active compound concentration is, for example, about 10 to 90% by weight, the remainder to make up 100% by weight comprising customary formulation constituents. In emulsifiable concentrates, the active compound concentration can be about 1 to 90, preferably 5 to 80% by weight. Dust-like formulations comprise 1 to 30% by weight of active compound, preferably usually 5 to 20% by weight of active compound, and sprayable solutions comprise about 0.05 to 80, preferably 2 to 50% by weight of active compound. In water-dispersible granules, the active compound content partly depends on whether the active compound is present in liquid or solid form and what granulating auxiliaries, fillers and the like are used. In water-dispersible granules, the content of active compound is, for example, between 1 and 95% by weight, preferably between 10 and 80% by weight.
In addition, the active compound formulations mentioned comprise, if appropriate, the particular customary tackifiers, wetting agents, dispersing agents, emulsifiers, penetration agents, preservatives, antifreezes and solvents, fillers, carrier substances and dyestuffs, defoamers, evaporation inhibitors and agents which influence the pH and viscosity.
Known active compounds such as are described, for example, in Weed Research 26, 441-445 (1986), or "The Pesticide Manual", 9th edition, The British Crop Protection Council, 1990/91, Bracknell, England, and literature mentioned therein can be employed as combination partners for the active compounds according to the invention in mixture formulations or in a tank mix. The following active compounds may be mentioned, for example, as herbicides which are known from the literature and can be combined with the compounds of the formula (I) (Note: The compounds are named either with the "common name" according to the International Organization for Standardization (ISO) or with the chemical name, if appropriate together with a customary code number):

For use, the formulations in the commercially available form are diluted in the customary manner, if appropriate, for example by means of water in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules. Dust-like formulations, soil or scattering granules and sprayable solutions are usually not diluted further with additional inert substances before use.
The required amount of compounds of the formula (I) to be applied varies with the outdoor conditions, such as temperature and humidity, the nature of the herbicide used and the like. It can vary within wide limits, for example between 0.001 and 10.0 kg/ha or more of active substance, but is preferably between 0.005 and 5 kg/ha.

CHEMICAL EXAMPLES
a) N-tert-Butyl-2-chloro-5-nitrobenzenesulfonamide
165 g of dried 2-chloro-5-nitrobenzenesulfonic acid sodium salt (90% pure) are initially introduced into 264 ml of acetonitrile, 264 ml of sulfolane and 16.5 ml of dimethylformamide (DMF). After dropwise addition of 198 ml of phosphorus oxychloride, the mixture is heated at the boiling point for 2 hours. After the mixture has been cooled, it is poured onto cold water and extracted with ethyl acetate, and the combined organic phases are dried over sodium sulfate and concentrated. The residue (mixture of sulfolane and 2-chloro-5-nitrobenzenesulfonyl chloride) is taken up in 1500 ml of methylene chloride, 130 ml of tert-butylamine are added (ice-bath cooling) and the mixture is stirred at room temperature for about 2 hours. After washing with dilute hydrochloric acid and drying over MgSO.sub.4, the organic phase is concentrated. The residue is stirred with methanol and cooled to 0.degree. C. The solid which has separated out (109 g, melting point 168.degree. to 171.degree. C.) is separated off and dried. A second fraction of the product of comparable quality (46.7 g) can be isolated analogously from the mother liquor.
b) N-tert-Butyl-2-ethylmercapto-5-nitrobenzenesulfonamide
5.6 ml of ethylmercaptan are added to a suspension of 20.0 g of N-tert-butyl-2-chloro-5-nitrobenzenesulfonamide, 18.9 g of potassium carbonate and 100 ml of DMF at room temperature. After the mixture has been stirred for 3 hours, it is concentrated under a high vacuum. The residue is taken up in water and acidified with concentrated hydrochloric acid (pH 1 to 2). The aqueous phase is extracted with ethyl acetate. The combined organic phases are dried over magnesium sulfate and then concentrated under reduced pressure. 21.25 g of the desired ethylmercaptan are thus obtained; melting point: 172.degree. to 174.degree. C.
c) 5-Amino-2-ethylmercapto-N-tert-butylbenzenesulfonamide
13.3 g of zinc powder are added in portions to a mixture of 12 g of N-tert-butyl-2-ethylmercapto-5-nitrobenzenesulfonamide, 17.7 g of ammonium chloride, 50 ml of water and 200 ml of ethanol and the mixture is stirred at 70.degree. C. for 10 hours. After the solid has been filtered off and washed out with ethyl acetate, the filtrate is concentrated under reduced pressure.

C. Biological examples
1. Action on weeds by the pre-emergence method
Seeds or pieces of rhizome of monocotyledon and dicotyledon weed plants are laid out in sandy loam soil in plastic pots and covered with soil. The compounds according to the invention, formulated in the form of wettable powders or emulsion concentrates, are then applied to the surface of the covering soil as an aqueous suspension or emulsion in various dosages with an amount of water applied, when converted, of 600 to 800 l/ha.
After the treatment, the pots are placed in a greenhouse and are kept under good growth conditions for the weeds. The plant damage or emergence damage is rated visually after emergence of the test plants after a test period of 3 to 4 weeks in comparison with untreated controls. As the test results show, the compounds according to the invention have a good herbicidal pre-emergence activity against a broad spectrum of graminaceous weeds and broad-leaved weeds. For example, Examples no. 1-26, 2-26, 3-1, 3-13, 3-16, 3-26, 3-51, 3-76, 3-101 and 3-103 (cf. Tables 1 and 3) have a very good herbicidal action against harmful plants such as Sinapis alba, Chrysanthemum segetum, Avena sativa, Stellaria media, Echinochloa crus-galli, Lolium multiflorum, Setaria spp., Abutilon theophrasti, Amaranthus retroflexus and Panicum miliaceum in the pre-emergence method when applied in an amount of 0.3 kg or less of active substance per hectare.
2. Action on weeds by the post-emergence method
Seeds or pieces of rhizome of mono- and dicotyledon weeds are laid out in sandy loam soil in plastic pots, covered with soil and grown in a greenhouse under good growth conditions. Three weeks after sowing, the test plants are treated in the trifoliate stage. The compounds according to the invention, formulated as wettable powders or as emulsion concentrates, are sprayed onto the green parts of the plants in various dosages with an amount of water applied, when converted, of 600 to 800 l/ha. After the test plants have stood in the greenhouse under optimum growth conditions for about 3 to 4 weeks, the action of the preparations is rated visually in comparison with untreated controls. The compositions according to the invention also have a good herbicidal activity against a broad spectrum of economically important graminaceous weeds and broad-leaved weeds in the post-emergence method. For example, Examples no. 1-26, 2-26, 3-1, 3-13, 3-16, 3-26, 3-51, 3-76, 3-101 and 3-103 (cf. Tables 1 and 3) have a very good herbicidal action against harmful plants such as Sinapis alba, Stellaria media, Echinochloa crus-galli, Lolium multiflorum, Chrysanthemum segetum, Setaria spp., Abutilon theophrasti, Amaranthus retroflexus, Panicum miliaceum and Avena sativa in the post-emergence method when applied in an amount of 0.3 kg or less of active substance per hectare.
3. Crop plant tolerance
In further experiments in the greenhouse, seeds of a relatively large number of crop plants and weeds are laid out in sandy loam soil and covered with soil. Some of the pots are treated immediately as described under Section 1, and the others are placed in a greenhouse until the plants have developed two to three true leaves, and are then sprayed with the substances of the formula (I) according to the invention in various dosages as described under Section 2. Four to five weeks after the application and standing time in the greenhouse, it is found by visual rating that the compounds according to the invention leave dicotyledonous crops such as, for example, soya, cotton, rape, sugar beet and potatoes, undamaged by the pre- and post-emergence method even at high dosages of active compound. Some substances furthermore also protect graminaceous crops, such as, for example, barley, wheat, rye, sorghum, millet, maize or rice. Some of the compounds of the formula (I) have a high selectivity and are therefore suitable for controlling undesirable plant growth in agricultural crops.
