N-(1,2,5-OXADIAZOL-3-YL)CARBOXAMIDE COMPOUNDS AND THEIR USE AS
HERBICIDES
Description
The present invention relates to substituted 1 ,2,5-oxadiazole compounds and the N- oxides and salts thereof and to compositions comprising the same. The invention also relates to the use of the 1 ,2,5-oxadiazole compounds or of the compositions comprising such compounds for controlling unwanted vegetation. Furthermore, the invention relates to methods of applying such compounds.
For the purposes of controlling unwanted vegetation, especially in crops, there is an ongoing need for new herbicides which have high activities and selectivities together with a substantial lack of toxicity for humans and animals.
EP 0 173 657 A1 describes N-(1 ,2,5-oxadiazol-3-yl) carboxamides, herbicidal compositions comprising them and the use of such compositions for controlling the growth of weeds.
WO 201 1/035874 describes N-(1 ,2,5-oxadiazol-3-yl) benzamides carrying 3 substituents in the 2-, 3- and 4-positions of the phenyl ring and their use as herbicides.
The N-(1 ,2,5-oxadiazol-3-yl) carboxamides of the prior art often suffer form insufficient herbicidal activity in particular at low application rates and/or unsatisfactory selectivity resulting in a low compatibility with crop plants.
Accordingly, it is an object of the present invention to provide further 1 ,2,5-oxadiazole compounds having a strong herbicidal activity, in particular even at low application rates, a sufficiently low toxicity for humans and animals and/or a high compatibility with crop plants. The 1 ,2,5-oxadiazole compounds should also show a broad activity spectrum against a large number of different unwanted plants.
These and further objectives are achieved by the compounds of formula I defined below and their N-oxides and also their agriculturally suitable salts.
It has been found that the above objectives can be achieved by substituted 1 ,2,5- oxadiazole compounds of the general formula I, as defined below, including their N-oxides and their salts, in particular their agriculturally suitable salts.
Therefore, in a first aspect the present invention relates to compounds of formula I,

The compounds of the formula I can be prepared by standard methods of organic chemistry, e.g. by the methods described hereinafter in schemes 1 to 5. The substituents, variables and indices in schemes 1 to 5 are as defined above for formula I, if not otherwise specified.
The compounds of formula I can be prepared for instance as shown in the Scheme 1 below.

III II I
4-Amino-1 ,2,5-oxadiazole compounds of formula III can be reacted with benzoyl derivatives of formula II to afford compounds of the formula I. Z is a leaving group, such as halogen, in particular CI, an anhydride residue or an active ester residue. Especially in case of Z being halogen the reaction is suitably carried out in the presence of a base. Suitable bases are for exam- pie carbonates, such as lithium, sodium or potassium carbonates, amines, such as trimethyla- mine or triethylamine, and basic N-heterocycles, such as pyridine, 2,6-dimethylpyridine or 2,4,6- trimethylpyridine. Suitable solvents are in particular aprotic solvents such as pentane, hexane, heptane, octane, cyclohexane, dichloromethane, chloroform, 1 ,2-dichlorethane, benzene, chlo- robenzene, toluene, the xylenes, dichlorobenzene, trimethylbenzene, pyridine, 2,6- dimethylpyridine, 2,4,6-trimethylpyridine, acetonitrile, diethyl ether, tetrahydrofuran, 2-methyl tetrahydrofuran, methyl tert-butylether, 1 ,4-dioxane, Ν,Ν-dimethyl formamide, N-methyl pyrroli- dinone or mixtures thereof. The starting materials are generally reacted with one another in equimolar or nearly equimolar amounts at a reaction temperature usually in the range of -20°C to 100°C and preferably in the range of -5°C to 50°C.
Alternatively, compounds of formula I can also be prepared as shown in Scheme 2. Reaction of a 4-amino-1 ,2,5-oxadiazole compound III with a benzoic acid derivative of formula IV yields compound I. The reaction is preferably carried in the presence of a suitable activating agent which converts the acid group of compound IV into an activated ester or amide. For this purpose activating agents known in the art, such as 1 ,1 ',carbonyldiimidazole (CDI), dicyclohexyl carbodiimide (DCC), 1 -ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) or 2,4,6-tripropyl- 1 ,3,5,2,4,6-trioxatriphosphorinane-2,4,6-trioxide (T3P) can be employed. The activated ester or amide can be formed, depending in particular on the specific activating agent used, either in situ by contacting compound IV with the activating agent in the presence of compound III, or in a separate step prior to the reaction with compound III. It may be advantageous, especially in cases where DCC or EDC are used as activating agent, to include further additives in the activating reaction, such as hydroxybenzotriazole (HOBt), nitrophenol, pentafluorophenol, 2,4,5- trichlorophenol or N-hydroxysuccinimide. It may further be advantageous to prepare the activated ester or amide in the presence of a base, for example a tertiary amine. The activated ester or amide is either in situ or subsequently reacted with the amine of formula III to afford the amide of formula I. The reaction normally takes place in anhydrous inert solvents, such as chlorinated hydrocarbons, e.g. dichloromethane or dichloroethane, ethers, e.g. tetrahydrofuran or 1 ,4- dioxane or carboxamides, e.g. N,N-dimethylformamide, Ν,Ν-dimethylacetamide or N- methylpyrrolidone. The reaction is ordinarily carried out at temperatures in the range from -20°C to +25°C.

The compounds of formula II and their respective benzoic acid precursors of formula IV can be obtained by purchase or can be prepared by processes known in the art or disclosed in the literature, e.g. in WO 2000/020408, WO 2001/040176, WO 96/30368, WO 97/30986, DE 4428000, WO 2002/048121 and WO 98/12192.
The 4-amino-1 ,2,5-oxadiazole compounds of the formula III are either commercially available or are obtainable according to methods known from the literature. For example, 3-alkyl-4- amino-1 ,2,5-oxadiazoles can be prepared from β-ketoesters pursuant to a procedure described in Russian Chemical Bulletin, Int. Ed., 54(4), 1032-1037 (2005), as depicted in Scheme 3.

As shown in Scheme 5, the compounds of the formula III, where R is a nudeophilic resi- due, can be prepared by introducing the nudeophilic residue via the substitution of a leaving group L, e.g. halogene, in the 4-position of the 1 ,2,5-oxadiazoles compounds of formula V in accordance to precedures disclosed, for example in Journal of Chemical Research, Synopses (6), 190 (1985), in Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya (9), 2086-8 (1986) or in Russian Chemical Bulletin (Translation of Izvestiya Akademii Nauk, Seriya Khimicheskaya), 53(3), 596-614 (2004).

As a rule, the compounds of formula I including their stereoisomers, salts, tautomers and N-oxides, and their precursors in the synthesis process, can be prepared by the methods described above. If individual compounds can not be prepared via the above-described routes, they can be prepared by derivatization of other compounds I or the respective precursor or by customary modifications of the synthesis routes described. For example, in individual cases, certain compounds of formula I can advantageously be prepared from other compounds of formula I by derivatization, e.g. by ester hydrolysis, amidation, esterification, ether cleavage, ole- fination, reduction, oxidation and the like, or by customary modifications of the synthesis routes described.
The reaction mixtures are worked up in the customary manner, for example by mixing with water, separating the phases, and, if appropriate, purifying the crude products by chromatography, for example on alumina or on silica gel. Some of the intermediates and end products may be obtained in the form of colorless or pale brown viscous oils which are freed or purified from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, they may be purified by recrystalliza- tion or trituration.
The compounds I and their agriculturally suitable salts are useful as herbicides. They are useful as such or as an appropriately formulated composition. The herbicidal compositions comprising the compound I, in particular the preferred aspects thereof, control vegetation on non-crop areas very efficiently, especially at high rates of application. They act against broad- leaved weeds and weed grasses in crops such as wheat, rice, corn, soybeans and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application.
Depending on the application method in question, the compounds I, in particular the pre- ferred aspects thereof, or compositions comprising them can additionally be employed in a further number of crop plants for eliminating unwanted plants. Examples of suitable crops are the following:
Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Avena sativa, Beta vulgaris spec, altissima, Beta vulgaris spec, rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Brassica oleracea, Brassica nigra, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus caro- ta, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arbo- reum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usi- tatissimum, Lycopersicon lycopersicum, Malus spec, Manihot esculenta, Medicago sativa, Mu- sa spec, Nicotiana tabacum (N.rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec, Pistacia vera, Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Prunus armeniaca, Prunus cerasus, Prunus dulcis and Prunus domestica, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Sinapis alba, Solanum tuberosum, Sorghum bicolor (s. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticale, Triticum durum, Vicia faba, Vitis vinifera, Zea mays.
The term "crop plants" also includes plants which have been modified by breeding, mutagenesis or genetic engineering. Genetically modified plants are plants whose genetic material has been modified in a manner which does not occur under natural conditions by crossing, mutations or natural recombination (i.e. reassembly of the genetic information). Here, in general, one or more genes are integrated into the genetic material of the plant to improve the properties of the plant.
Accordingly, the term "crop plants" also includes plants which, by breeding and genetic engineering, have acquired tolerance to certain classes of herbicides, such as hydroxy- phenylpyruvate dioxygenase (HPPD) inhibitors, acetolactate synthase (ALS) inhibitors, such as, for example, sulfonylureas (EP-A-0257993, US 5,013,659) or imidazolinones (see, for example, US 6,222,100, WO 01/82685, WO 00/26390, WO 97/41218, WO 98/02526, WO 98/02527, WO 04/106529, WO 05/20673, WO 03/14357, WO 03/13225, WO 03/14356, WO 04/16073), enolpyruvylshikimate 3-phosphate synthase (EPSPS) inhibitors, such as, for example, glypho- sate (see, for example, WO 92/00377), glutamine synthetase (GS) inhibitors, such as, for example, glufosinate (see, for example, EP-A-0242236, EP-A-242246), or oxynil herbicides (see, for example, US 5,559,024).
Numerous crop plants, for example Clearfield® oilseed rape, tolerant to imidazolinones, for example imazamox, have been generated with the aid of classic breeding methods (mutagenesis). Crop plants such as soybeans, cotton, corn, beet and oilseed rape, resistant to glyphosate or glufosinate, which are available under the tradenames RoundupReady® (glypho- sate) and Liberty Link® (glufosinate) have been generated with the aid of genetic engineering methods.
Accordingly, the term "crop plants" also includes plants which, with the aid of genetic en- gineering, produce one or more toxins, for example those of the bacterial strain Bacillus ssp. Toxins which are produced by such genetically modified plants include, for example, insecticidal proteins of Bacillus spp., in particular B. thuringiensis, such as the endotoxins CrylAb, Cry1 Ac, Cry1 F, Cry1 Fa2, Cry2Ab, Cry3A, Cry3Bb1 , Cry9c, Cry34Ab1 or Cry35Ab1 ; or vegetative insecticidal proteins (VI Ps), for example VI P1 , VI P2, VI P3, or VIP3A; insecticidal proteins of nema- tode-colonizing bacteria, for example Photorhabdus spp. or Xenorhabdus spp.; toxins of animal organisms, for example wasp, spider or scorpion toxins; fungal toxins, for example from Strep- tomycetes; plant lectins, for example from peas or barley; agglutinins; proteinase inhibitors, for example trypsin inhibitors, serine protease inhibitors, patatin, cystatin or papain inhibitors, ribo- some-inactivating proteins (RIPs), for example ricin, corn-RIP, abrin, luffin, saporin or bryodin; steroid-metabolizing enzymes, for example 3-hydroxysteroid oxidase, ecdysteroid-IDP glycosyl transferase, cholesterol oxidase, ecdysone inhibitors, or HMG-CoA reductase; ion channel blockers, for example inhibitors of sodium channels or calcium channels; juvenile hormone esterase; receptors of the diuretic hormone (helicokinin receptors); stilbene synthase, bibenzyl synthase, chitinases and glucanases. In the plants, these toxins may also be produced as pre- toxins, hybrid proteins or truncated or otherwise modified proteins. Hybrid proteins are characterized by a novel combination of different protein domains (see, for example, WO
2002/015701 ). Further examples of such toxins or genetically modified plants which produce these toxins are disclosed in EP-A 374 753, WO 93/007278, WO 95/34656, EP-A 427 529, EP- A 451 878, WO 03/018810 and WO 03/052073. The methods for producing these genetically modified plants are known to the person skilled in the art and disclosed, for example, in the publications mentioned above. Numerous of the toxins mentioned above bestow, upon the plants by which they are produced, tolerance to pests from all taxonomic classes of arthropods, in particular to beetles (Coeleropta), dipterans (Diptera) and butterflies (Lepidoptera) and to nematodes (Nematoda).
Genetically modified plants which produce one or more genes coding for insecticidal toxins are described, for example, in the publications mentioned above, and some of them are commercially available, such as, for example, YieldGard® (corn varieties producing the toxin CrylAb), YieldGard® Plus (corn varieties which produce the toxins CrylAb and Cry3Bb1 ), Star- link® (corn varieties which produce the toxin Cry9c), Herculex® RW (corn varieties which pro- duce the toxins Cry34Ab1 , Cry35Ab1 and the enzyme phosphinothricin-N-acetyltransferase [PAT]); NuCOTN® 33B (cotton varieties which produce the toxin CrylAc), Bollgard® I (cotton varieties which produce the toxin CrylAc), Bollgard® II (cotton varieties which produce the toxins CrylAc and Cry2Ab2); VIPCOT® (cotton varieties which produce a VIP toxin); NewLeaf® (potato varieties which produce the toxin Cry3A); Bt-Xtra®, NatureGard®, KnockOut®, BiteGard®, Protecta®, Bt1 1 (for example Agrisure® CB) and Bt176 from Syngenta Seeds SAS, France (corn varieties which produce the toxin CrylAb and the PAT enyzme), MIR604 from Syngenta Seeds SAS, France (corn varieties which produce a modified version of the toxin Cry3A, see
WO 03/018810), MON 863 from Monsanto Europe S.A., Belgium (corn varieties which produce the toxin Cry3Bb1 ), IPC 531 from Monsanto Europe S.A., Belgium (cotton varieties which produce a modified version of the toxin CrylAc) and 1507 from Pioneer Overseas Corporation, Belgium (corn varieties which produce the toxin Cry1 F and the PAT enzyme).
Accordingly, the term "crop plants" also includes plants which, with the aid of genetic engineering, produce one or more proteins which are more robust or have increased resistance to bacterial, viral or fungal pathogens, such as, for example, pathogenesis-related proteins (PR proteins, see EP-A 0 392 225), resistance proteins (for example potato varieties producing two resistance genes against Phytophthora infestans from the wild Mexican potato Solanum bulbocastanum) or T4 lysozyme (for example potato cultivars which, by producing this protein, are resistant to bacteria such as Erwinia amylvora).
Accordingly, the term "crop plants" also includes plants whose productivity has been improved with the aid of genetic engineering methods, for example by enhancing the potential yield (for example biomass, grain yield, starch, oil or protein content), tolerance to drought, salt or other limiting environmental factors or resistance to pests and fungal, bacterial and viral pathogens.
The term "crop plants" also includes plants whose ingredients have been modified with the aid of genetic engineering methods in particular for improving human or animal diet, for ex- ample by oil plants producing health-promoting long-chain omega 3 fatty acids or monounsatu- rated omega 9 fatty acids (for example Nexera® oilseed rape).
The term "crop plants" also includes plants which have been modified with the aid of genetic engineering methods for improving the production of raw materials, for example by increasing the amylopectin content of potatoes (Amflora® potato).
Furthermore, it has been found that the compounds of the formula I are also suitable for the defoliation and/or desiccation of plant parts, for which crop plants such as cotton, potato, oilseed rape, sunflower, soybean or field beans, in particular cotton, are suitable. In this regard, there have been found compositions for the desiccation and/or defoliation of plants, processes for preparing these compositions and methods for desiccating and/or defoliating plants using the compounds of the formula I.
As desiccants, the compounds of the formula I are particularly suitable for desiccating the above-ground parts of crop plants such as potato, oilseed rape, sunflower and soybean, but also cereals. This makes possible the fully mechanical harvesting of these important crop plants.
Also of economic interest is to facilitate harvesting, which is made possible by
concentrating within a certain period of time the dehiscence, or reduction of adhesion to the tree, in citrus fruit, olives and other species and varieties of pomaceous fruit, stone fruit and nuts. The same mechanism, i.e. the promotion of the development of abscission tissue between fruit part or leaf part and shoot part of the plants is also essential for the readily controllable defoliation of useful plants, in particular cotton.
Moreover, a shortening of the time interval in which the individual cotton plants mature leads to an increased fiber quality after harvesting.
The compounds I, or the herbicidal compositions comprising the compounds I, can be used, for example, in the form of ready-to-spray aqueous solutions, powders, suspensions, also highly concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for broadcasting, or granules, by means of spraying, atomizing, dusting, spreading, watering or treatment of the seed or mixing with the seed. The use forms depend on the intended purpose; in each case, they should ensure the finest possible distribution of the active ingredients according to the invention.
The herbicidal compositions comprise a herbicidally effective amount of at least one compound of the formula I or an agriculturally useful salt of I, and auxiliaries which are customary for the formulation of crop protection agents.
Examples of auxiliaries customary for the formulation of crop protection agents are inert auxiliaries, solid carriers, surfactants (such as dispersants, protective colloids, emulsifiers, wetting agents and tackifiers), organic and inorganic thickeners, bactericides, antifreeze agents, antifoams, if appropriate colorants and, for seed formulations, adhesives.
Examples of thickeners (i.e. compounds which impart to the formulation modified flow properties, i.e. high viscosity in the state of rest and low viscosity in motion) are
polysaccharides, such as xanthan gum (Kelzan® from Kelco), Rhodopol® 23 (Rhone Poulenc) or Veegum® (from R.T. Vanderbilt), and also organic and inorganic sheet minerals, such as Attaclay® (from Engelhardt).
Examples of antifoams are silicone emulsions (such as, for example, Silikon® SRE, Wacker or Rhodorsil® from Rhodia), long-chain alcohols, fatty acids, salts of fatty acids, organofluorine compounds and mixtures thereof.
Bactericides can be added for stabilizing the aqueous herbicidal formulation. Examples of bactericides are bactericides based on diclorophen and benzyl alcohol hemiformal (Proxel® from ICI or Acticide® RS from Thor Chemie and Kathon® MK from Rohm & Haas), and also isothiazolinone derivates, such as alkylisothiazolinones and benzisothiazolinones (Acticide MBS from Thor Chemie).

Powders, materials for broadcasting and dusts can be prepared by mixing or grinding the active ingredients together with a solid carrier.
Granules, for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers.
Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the compounds of the formula I or la, either as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is also possible to prepare concentrates comprising active substance, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, which are suitable for dilution with water.
The concentrations of the compounds of the formula I in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise from 0.001 to 98% by weight, preferably 0.01 to 95% by weight of at least one active compound. The active compounds are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).
The formulations or ready-to-use preparations may also comprise acids, bases or buffer systems, suitable examples being phosphoric acid or sulfuric acid, or urea or ammonia.
The compounds I of the invention can for example be formulated as follows:
1 . Products for dilution with water
A Water-soluble concentrates
10 parts by weight of active compound are dissolved in 90 parts by weight of water or a water-soluble solvent. As an alternative, wetters or other adjuvants are added. The active compound dissolves upon dilution with water. This gives a formulation with an active compound content of 10% by weight.
B Dispersible concentrates
20 parts by weight of active compound are dissolved in 70 parts by weight of cyclohexa- none with addition of 10 parts by weight of a dispersant, for example polyvinylpyrrolidone. Dilution with water gives a dispersion. The active compound content is 20% by weight.
C Emulsifiable concentrates
15 parts by weight of active compound are dissolved in 75 parts by weight of an organic solvent (e.g. alkylaromatics) with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5 parts by weight).

J Granules (GR, FG, GG, MG)
0.5 parts by weight of active compound are ground finely and associated with 99.5 parts by weight of carriers. Current methods here are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted with an active compound content of 0.5% by weight.
K ULV solutions (UL)
10 parts by weight of active compound are dissolved in 90 parts by weight of an organic solvent, for example xylene. This gives a product to be applied undiluted with an active compound content of 10% by weight.
The compounds I or the herbicidal compositions comprising them can be applied pre- or post-emergence, or together with the seed of a crop plant. It is also possible to apply the herbicidal compositions or active compounds by applying seed, pretreated with the herbicidal compositions or active compounds, of a crop plant. If the active compounds are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that as far as possible they do not come into contact with the leaves of the sensitive crop plants, while the active compounds reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).
In a further embodiment, the compounds of the formula I or the herbicidal compositions can be applied by treating seed.
The treatment of seed comprises essentially all procedures familiar to the person skilled in the art (seed dressing, seed coating, seed dusting, seed soaking, seed film coating, seed multilayer coating, seed encrusting, seed dripping and seed pelleting) based on the compounds of the formula I according to the invention or the compositions prepared therefrom. Here, the herbicidal compositions can be applied diluted or undiluted.
The term seed comprises seed of all types, such as, for example, corns, seeds, fruits, tu- bers, cuttings and similar forms. Here, preferably, the term seed describes corns and seeds. The seed used can be seed of the useful plants mentioned above, but also the seed of transgenic plants or plants obtained by customary breeding methods.
The rates of application of active compound are from 0.001 to 3.0, preferably 0.01 to 1.0, kg/ha of active substance (a.s.), depending on the control target, the season, the target plants and the growth stage. To treat the seed, the compounds I are generally employed in amounts of from 0.001 to 10 kg per 100 kg of seed.
It may also be advantageous to use the compounds of the formula I in combination with safeners. Safeners are chemical compounds which prevent or reduce damage to useful plants without substantially affecting the herbicidal action of the compounds of the formula I on un- wanted plants. They can be used both before sowing (for example in the treatment of seed, or on cuttings or seedlings) and before or after the emergence of the useful plant. The safeners and the compounds of the formula I can be used simultaneously or in succession. Suitable safeners are, for example, (quinolin-8-oxy)acetic acids, 1 -phenyl-5-haloalkyl-1 /-/-1 ,2,4-triazole-3- carboxylic acids, 1 -phenyl-4,5-dihydro-5-alkyl-1 H-pyrazole-3,5-dicarboxylic acids, 4,5-dihydro- 5,5-diaryl-3-isoxazolecarboxylic acids, dichloroacetamides, alpha-oximinophenylacetonitriles, acetophenone oximes, 4,6-dihalo-2-phenylpyrimidines, N-[[4-(aminocarbonyl)phenyl]sulfonyl]-2- benzamides, 1 ,8-naphthalic anhydride, 2-halo-4-(haloalkyl)-5-thiazolecarboxylic acids, phos- phorothiolates and O-phenyl N-alkylcarbamates and their agriculturally useful salts and, provided that they have an acid function, their agriculturally useful derivatives, such as amides, esters and thioesters.
To broaden the activity spectrum and to obtain synergistic effects, the compounds of the formula I can be mixed and jointly applied with numerous representatives of other herbicidal or growth-regulating groups of active compounds or with safeners. Suitable mixing partners are, for example, 1 ,2,4-thiadiazoles, 1 ,3,4-thiadiazoles, amides, aminophosphoric acid and its deriv- atives, aminotriazoles, anilides, aryloxy/heteroaryloxyalkanoic acids and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(hetaroyl/aroyl)-1 ,3-cyclohexanediones, heteroaryl aryl ketones, benzylisoxazolidinones, meta-CF3-phenyl derivatives, carbamates, quinoline carboxylic acid and its derivatives, chloroacetanilides, cyclohexenone oxime ether derivates, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofu- ran-3-ones, dinitroanilines, dinitrophenols, diphenyl ethers, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6- tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and heteroaryloxyphenoxypro- pionic esters, phenylacetic acid and its derivatives, 2-phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolecarboxamides, uracils and also phenylpyrazolines and isoxazolines and their derivatives.
Moreover, it may be useful to apply the compounds I alone or in combination with other herbicides or else also mixed with further crop protection agents, jointly, for example with compositions for controlling pests or phytopathogenic fungi or bacteria. Also of interest is the misci- bility with mineral salt solutions which are employed for alleviating nutritional and trace element deficiencies. Other additives such as nonphytotoxic oils and oil concentrates may also be added.

The compounds I and the compositions according to the invention may also have a plant- strengthening action. Accordingly, they are suitable for mobilizing the defense system of the plants against attack by unwanted microorganisms, such as harmful fungi, but also viruses and bacteria. Plant-strengthening (resistance-inducing) substances are to be understood as meaning, in the present context, those substances which are capable of stimulating the defense system of treated plants in such a way that, when subsequently inoculated by unwanted microorganisms, the treated plants display a substantial degree of resistance to these microorganisms.
The compounds I can be employed for protecting plants against attack by unwanted mi- croorganisms within a certain period of time after the treatment. The period of time within which their protection is effected generally extends from 1 to 28 days, preferably from 1 to 14 days, after the treatment of the plants with the compounds I, or, after treatment of the seed, for up to 9 months after sowing. The compounds I and the compositions according to the invention are also suitable for increasing the harvest yield.
Moreover, they have reduced toxicity and are tolerated well by the plants.
II. Use examples
The herbicidal activity of the compunds of the formula I was demonstrated by the following greenhouse experiments:
The culture containers used were plastic flowerpots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.
For the pre-emergence treatment, the active ingredients, which had been suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants, unless this has been impaired by the active ingredients.
For the post-emergence treatment, the test plants were first grown to a height of 3 to 15 cm, depending on the plant habit, and only then treated with the active ingredients which had been suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment.
Depending on the species, the plants were kept at 10-25°C or 20-35°C. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.
Evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the aerial moieties, and 0 means no damage, or normal course of growth. A good herbicidal activity is given at values of at least 70 and a very good herbicidal activity is given at values of at least 85.
