## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a §371 National Stage Application of PCT/EP07/09345 filed Oct. 27, 2007 which claims priority to European Application 06023578.5 filed Nov. 13, 2006.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is in the technical field of crop protection products which can be employed against harmful plants, for example in crop plants, and which comprise, as active compounds, a combination of at least two specific herbicides.
2. Description of Related Art
The document EP-A-131258 discloses sulfonylureas and their salts and also their use as herbicides and/or plant growth regulators.
The efficacy of these herbicides against harmful plants in the crop plants is at a high level, but depends in general on the application rate, the formulation in question, the harmful plants or spectrum of harmful plants to be controlled in each case, the climatic conditions, the soil conditions and the like. Another criterion is the duration of action, or the breakdown rate of the herbicide. If appropriate, changes in the sensitivity of harmful plants, which may occur upon prolonged use of the herbicides or within geographic limitations, must also be taken into consideration. The compensation of losses in action in the case of individual harmful plants by increasing the application rates of the herbicides is only possible to a certain degree, for example because such a procedure frequently reduces the selectivity of the herbicides or because the action is not improved, even when applying higher rates. In some cases, the selectivity in crops can be improved by adding safeners. In general, however, there remains a need for methods to achieve the herbicidal action with a lower application rate of active compounds. Not only does a lower application rate reduce the amount of an active compound required for application, but, as a rule, it also reduces the amount of formulation auxiliaries required. It both reduces the economic input and improves the ecological compatibility of the herbicide treatment.
One possibility of improving the application profile of a herbicide can consist in combining the active compound with one or more other active compounds. However, the combined use of a plurality of active compounds frequently causes phenomena of physical and biological incompatibility, for example a lack of stability in a coformulation, decomposition of an active compound, or antagonism of the active compounds. What is desired are, in contrast, combinations of active compounds having an advantageous activity profile, high stability and, if possible, a synergistically improved action, which allows the application rate to be reduced in comparison with the individual application of the active compounds to be combined.
SUMMARY OF THE INVENTION
Surprisingly, it has now been found that certain active compounds from the group of the sulfonylureas or their salts in combination with certain structurally different herbicides act together in a particularly advantageous manner, for example when they are employed in crop plants.
The invention thus provides herbicide combinations comprising components (A) and (B), where

    (A) denotes one or more herbicides of the formula (I) and their salts






and

    (B) denotes one or more herbicides selected from the group of the compounds of the formula (II) and their salts and esters,






    
    
        in which
        R1=is fluorine or chlorine,
        R2=is H or chlorine,
        R3=is H or NH2, and
        R4=is COOH, OCH2COOH, OCH2COOCH(CH3)CH2O(CH2)3CH3 or OCH2COOCH(CH3)(CH2)5CH3,
        where at least one of the radicals R2 and R3 is different from H.
    
    




DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Preferred compounds of the formula (II) are (listed with the “common name” and a literature reference, for example from “The Pesticide Manual” 14th Ed., British Crop Protection Council 2006, abbreviated as “PM”)

    (B1) picloram, in particular also including its salts and esters (PM, pp. 838-840), for example 4-amino-3,5,6-trichloropyridine-2-carboxylic acid (application rate generally: 20-300 g of AS/ha, preferably 50-150 g of AS/ha; application rate ratio A:B generally =1:1-1:50, preferably 1:2-1:10);
    (B2) aminopyralid, in particular also including its salts and esters (PM, pp. 30-31), for example 4-amino-3,6-dichloropyridine-2-carboxylic acid (application rate generally: 10-200 g of AS/ha, preferably 30-70 g of AS/ha; application rate ratio A:B generally =1:1-1:20, preferably 1:1-1:5);
    (B3) triclopyr, in particular also including its salts and esters (PM, pp. 1068-1069), for example 3,5,6-trichloro-2-pyridyloxyacetic acid (application rate generally: 50-300 g of AS/ha, preferably 100-200 g of AS/ha; application rate ratio A:B generally =1:1-1:20, preferably 1:2-1:10);
    (B4) fluoroxypyr, in particular also including its salts and esters (PM, pp. 509-511) for example 4-amino-3,5-dichloro-6-fluoro-2-pyridylacetic acid (application rate generally: 50-300 g of AS/ha, preferably 100-200 g of AS/ha; application rate ratio A:B generally =1:1-1:20, preferably 1:2-1:10.


Preferred mixing partners (B) are picloram (B1.1), picloram-dimethylammonium (B1.2), picloram-isoctyl (B1.3), picloram-sodium (B1.4), picloram-potassium (B1.5), picloram-triisopropanolammonium (B1.6), picloram-triethanolammonium (=picloram-trolamine) (B1.7), picloram-triisopropylammonium (B1.8), aminopyralid (B2.1), aminopyralid-sodium (B2.2), aminopyralid-potassium (B2.3), aminopyralid-tri(2-hydroxypropyl)ammonium (B2.4), triclopyr (B3.1), triclopyr-butotyl (B3.2), triclopyr-triethylammonium (B3.3), fluoroxypyr (B4.1), fluoroxypyr-2-butoxy-1-methylethyl (B4.2), fluoroxypyr-1-methylheptyl (B4.3).
The herbicide combinations according to the invention comprise a herbicidally effective amount of components (A) and (B) and may comprise further components, for example agrochemically active compounds of a different type and/or formulation auxiliaries and/or additives customary in crop protection, or they may be employed together with these.
In a preferred embodiment, the herbicide combinations according to the invention have synergistic effects. The synergistic effects can be observed, for example, when the active compounds (A) and (B) are applied together, but they can frequently also be observed when the compounds are applied as a split application over time. Another possibility is the application of the individual herbicides or the herbicide combinations in a plurality of portions (sequential application), for example after pre-emergence applications, followed by post-emergence applications or after early post-emergence applications, followed by applications at medium or late post-emergence. Preferred is the simultaneous or nearly simultaneous application of the active compounds of the herbicide combination according to the invention.
The synergistic effects allow the application rates of the individual active compounds to be reduced, a more potent action at the same application rate, the control of hitherto uncontrollable species (activity gaps), an extended application period and/or a reduced number of individual applications required and—as a result for the user—more advantageous weed control systems both from an economical and ecological point of view.
The abovementioned formulae (I) and (III) include all stereoisomers and their mixtures, in particular also racemic mixtures and—if enantiomers are possible—the respective biologically active enantiomer. The compounds of the formulae (I) and (II) are capable of forming salts, for example, in which a hydrogen atom is replaced by an agriculturally suitable cation. These salts are, for example, metal salts, in particular alkali metal salts or alkaline earth metal salts, in particular sodium and potassium salts, or else ammonium salts or salts with organic amines. Salt formation may also take place by addition of an acid to basic groups, such as, for example, amino and alkylamino. Acids suitable for this purpose are strong inorganic and organic acids, for example HCl, HBr, H2SO4 or HNO3. Compounds of the formula (I) and their salts and also their preparation are described, for example, in EP-A-131258 and U.S. Pat. No. 4,718,937. Preferred compounds of the formula (I) and their salts are 1-(4,6-dimethoxypyrimidin-2-yl)-3-mesyl(methyl)sulfamoylurea (amidosulfuron, A1.1) and its sodium salt (A1.2) (see, for example, EP-A-131258 and PM, pp. 27-28).
The abovementioned active compounds of the formula (I) and their salts are capable of inhibiting the enzyme acetolactate synthase (ALS) and thus protein synthesis in plants. The application rate of the active compounds of the formula (I) and their salts can be varied within a wide range, for example between 1 g and 500 g of AS/ha (AS/ha means “active substance per hectare”, based on 100% active compound). In the case of applications at application rates of from 10 g to 300 g of AS/ha of the active compounds of the formula (I) and their salts, preferably the active compounds (A1.1), (A1.2), a relatively broad spectrum of harmful plants is controlled pre- and post-emergence. In the combinations according to the invention, the application rates are generally lower, for example in the range from 0.5 to 200 g of AS/ha, preferably from 1 to 120 g of AS/ha.
If, in the context of this description, the short form of the “common name” of an active compound is used, this embraces all customary derivatives, such as the esters and salts, and isomers, in particular optical isomers, in particular the commercial form or forms, unless the context indicates otherwise. Also included in the case of sulfonamides such as sulfonylureas are salts which are formed by exchanging a hydrogen atom at the sulfonamide group by a cation.
Of particular interest are herbicide combinations according to the invention having a content of the following compounds (A)+(B):

    (A1.1)+(B1.1), (A1.1)+(B1.2), (A1.1)+(B1.3), (A1.1)+(B1.4), (A1.1)+(B1.5), (A1.1)+(B1.6), (A1.1)+(B1.7), (A1.1)+(B1.8), (A1.1)+(B2.1), (A1.1)+(B2.2), (A1.1)+(B2.3), (A1.1)+(B2.4), (A1.1)+(B3.1), (A1.1)+(B3.2), (A1.1)+(B3.3), (A1.1)+(B4.1), (A1.1)+(B4.2), (A1.1)+(B4.3);
    (A1.2)+(B1.1), (A1.2)+(B1.2), (A1.2)+(B1.3), (A1.2)+(B1.4), (A1.2)+(B1.5), (A1.2)+(B1.6), (A1.2)+(B1.7), (A1.2)+(B1.8), (A1.2)+(B2.1), (A1.2)+(B2.2), (A1.2)+(B2.3), (A1.2)+(B2.4), (A1.2)+(B3.1), (A1.2)+(B3.2), (A1.2)+(B3.3), (A1.2)+(B4.1), (A1.2)+(B4.2), (A1.2)+(B4.3).


It may be advantageous to combine one or more compounds (A) with a plurality of compounds (B), or to combine a plurality of compounds (A) with one or more compounds (B). Furthermore, the combinations according to the invention may comprise agrochemically active compounds of a different structure (active compounds (C)), for example from the group of the safeners, fungicides, herbicides, insecticides and plant growth regulators or formulation auxiliaries and additives customary in crop protection, or they may be used together with these. For such combinations, the preferred conditions illustrated below in particular for combinations (A)+(B) according to the invention also primarily apply, provided they comprise the combinations (A)+(B) according to the invention, and with respect to the combination (A)+(B) in question. Additives are, for example, fertilizers and colorants. Preferred agrochemically active compounds (C) are herbicides and/or safeners.

The herbicide combinations according to the invention (=herbicidal compositions) have an outstanding herbicidal activity against a broad spectrum of economically important harmful plants. Here, the substances can be applied by the pre-sowing, the pre-emergence and/or the post-emergence method, for example jointly or separately. Post-emergence application, or early pre-emergence application, is preferred.
Specifically, examples may be mentioned of some representatives of the dicotyledonous weed flora which can be controlled by the combinations according to the invention, without the enumeration being a restriction to certain species: Abutilon spp., Amaranthus spp., Chenopodium spp., Chrysanthemum spp., Galium spp. such as Galium aparine, lpomoea spp., Kochia spp., Lamium spp., Matricaria spp., Pharbitis spp., Polygonum spp., Sida spp., Sinapis spp., Solanum spp., Stellaria spp., Veronica spp. and Viola spp., Xanthium spp. from among the annual weeds and Convolvulus, Cirsium, Rumex and Artemisia from among the perennial weeds, and also Acacia spp., Acalypha acalopecurus, Ageratum conyzoides, Ammis majus, Apium leptophyllium, Asclepias curassayica, Baccharis coridifolia, Bauhinia spp., Baltimora recta, Boehmeria niveam, Bowlesia incana, Cassia occidentalis, Carduus acanthoides, Cassia tora, Chamaecrysta trichopoda, Cirsium vulgare, Cleome viscosa, Clidemia Hirta, Conyza bonariensis, Coronopus didimus, Crotalaria spp., Eclipta alba, Elephantopus spicatus, Eupatorium squalidum, Euphorbia spp., Fumaria capriolata, Fumaria officinalis, Gamochaeta spicata, Gnaphallium spp., Heliconia bijai, Hyptis suaveolens, Lantana camara, Lippia nudiflora, Ludwigia octovalvis, Malva spp., Melampodium spp., Mimosa spp., Mucuna pririens, Nephrolepsis spp., Pachira odorata, Petiveria alleacea, Phitecollobium spp., Pisonia aculeata, Plantago lanceolata, Plantago major, Priva lapulacea, Prosopis juliflora, Pteridium aquilinum, Rauvolfia tetraphilla, Ricinus comunis, Scleria pterota, Senecio brasiliensis, Senna obtusifolia, Silibum marianun, Tecoma stans, Thalia geniculata, Vernonia spp., Viguiera dentata, Wissadula amplissima. 
If the herbicide combinations according to the invention are applied to the soil surface before germination, then the weed seedlings are either prevented completely from emerging, or the weeds grow until they have reached the cotyledon stage but then their growth stops, and, eventually, after three to four weeks have elapsed, they die completely.
If the active compounds are applied post-emergence to the green parts of the plants, growth likewise stops drastically a very short time after the treatment and the weed plants remain at the growth stage of the point in time of application, or they die completely after a certain time, so that in this manner competition by the weeds, which is harmful to the crop plants, is eliminated at a very early point in time and in a sustained manner.
The herbicidal compositions according to the invention are distinguished by a rapidly commencing and long-lasting herbicidal action. As a rule, the rainfastness of the active compounds in the combinations according to the invention is advantageous. A particular advantage is that the dosages of the compounds (A) and (B), which are used in the combinations and are effective, can be adjusted to such a low quantity that their soil action is optimally low. Not only does this allow them to be employed in sensitive crops in the first place, but groundwater contaminations are virtually avoided. The herbicide combination according to the invention allows the application rate of the active compounds required to be reduced considerably.
In a preferred embodiment, when herbicides of the type (A)+(B) are used jointly, superadditive (=synergistic) effects are observed. This means that the effect in the combinations exceeds the expected total of the effects of the individual herbicides employed. The synergistic effects allow the application rate to be reduced, a broader spectrum of broad-leaved weeds and grass weeds to be controlled, the herbicidal action to take place more rapidly, the duration of action to be longer, the harmful plants to be controlled better while using only one, or few, applications, and the application period which is possible to be extended.
The abovementioned properties and advantages are of benefit for weed control practice to keep agricultural crops free from undesired competing plants and thus to safeguard and/or increase the yields from the qualitative and quantitative point of view. These novel combinations markedly exceed the technical state of the art with a view to the properties described.
While the combinations according to the invention have an outstanding herbicidal activity against harmful plants, the crop plants are damaged only to a minor extent, if at all.
Moreover, some of the combinations according to the invention have outstanding growth-regulatory properties on the crop plants. They engage in the plants' metabolism in a regulatory manner and can thus be employed for provoking directed effects on plant constituents and to facilitate harvesting such as for example by triggering desiccation and stunted growth. Moreover, they are also suitable for the general control and inhibition of undesired vegetative growth without simultaneously destroying the plants. An inhibition of vegetative growth is very important in a large number of monocotyledonous and dicotyledonous crops since yield losses as a result of lodging can thus be reduced, or prevented completely.
Owing to their herbicidal and plant-growth-regulatory properties, the combinations according to the invention can also be employed for controlling harmful plants in genetically modified crop plants or crop plants obtained by mutation/selection. These crop plants are distinguished as a rule by particular, advantageous properties, such as resistances to herbicidal compositions or resistances to plant diseases or causative agents of plant diseases such as particular insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the harvested material with regard to quantity, quality, storability, composition and specific constituents. Thus, for example, transgenic plants are known whose starch content is increased or whose starch quality is altered, or those where the harvested material has a different fatty acid composition.
Conventional methods of generating novel plants which have modified properties in comparison to plants occurring to date consist, for example, in traditional breeding methods and the generation of mutants (see, for example, U.S. Pat. No. 5,162,602; U.S. Pat. No. 4,761,373; U.S. Pat. No. 4,443,971). Alternatively, novel plants with altered properties can be generated with the aid of recombinant methods (see, for example, EP-A-0221044, EP-A-0131624). For example, the following have been described in several cases:

    
    
        the modification, by recombinant technology, of crop plants with the aim of modifying the starch synthesized in the plants (for example WO 92/11376, WO 92/14827, WO 91/19806),
        transgenic crop plants which exhibit resistances to other herbicides, for example to sulfonylureas (EP-A-0257993, U.S. Pat. No. 5,013,659),
        transgenic crop plants with the capability of producing Bacillus thuringiensis toxins (Bt toxins), which make the plants resistant to certain pests (EP-A-0142924, EP-A-0193259),
        transgenic crop plants with a modified fatty acid composition (WO 91/13972).
    
    


A large number of techniques in molecular biology are known in principle with the aid of which novel transgenic plants with modified properties can be generated: see, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2nd Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y.; or Winnacker “Gene und Klone”, VCH Weinheim 2nd Edition 1996 or Christou, “Trends in Plant Science” 1 (1996) 423-431).
To carry out such recombinant manipulations, nucleic acid molecules which allow mutagenesis or sequence changes by recombination of DNA sequences can be introduced into plasmids. For example, the abovementioned standard methods allow base exchanges to be carried out, subsequences to be removed, or natural or synthetic sequences to be added. To connect the DNA fragments to each other, adapters or linkers may be added to the fragments.
For example, the generation of plant cells with a reduced activity of a gene product can be achieved by expressing at least one corresponding antisense RNA, a sense RNA for achieving a cosuppression effect or by expressing at least one suitably constructed ribozyme which specifically cleaves transcripts of the abovementioned gene product.
To this end, it is possible to use DNA molecules which encompass the entire coding sequence of a gene product inclusive of any flanking sequences which may be present, and also DNA molecules which only encompass portions of the coding sequence, it being necessary for these portions to be long enough to have an antisense effect in the cells. The use of DNA sequences which have a high degree of homology to the encoding sequences of a gene product, but are not completely identical to them, is also possible.
When expressing nucleic acid molecules in plants, the protein synthesized can be localized in any desired compartment of the plant cell. However, to achieve localization in a particular compartment, it is possible, for example, to link the coding region with DNA sequences which ensure localization in a particular compartment. Such sequences are known to those skilled in the art (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al., Proc. Natl. Acad. Sci. USA 85 (1988), 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106).
The transgenic plant cells can be regenerated by known techniques to give rise to intact plants. In principle, the transgenic plants can be plants of any desired plant species, i.e. not only monocotyledonous, but also dicotyledonous, plants. Thus, transgenic plants can be obtained whose properties are altered by overexpression, suppression or inhibition of homologous (=natural) genes or gene sequences or the expression of heterologous (=foreign) genes or gene sequences.
The present invention furthermore provides a method for controlling unwanted plant growth, preferably in plant crops such as monocotyledonous or dicotyledonous plant crops, for example pasture crops, cereals (for example wheat, barley, rye, oats, rice, corn and millet), sugar beet, sugar cane, oilseed rape, cotton and soybeans, preferably in monocotyledonous crops such as pasture crops or cereals (for example wheat, barley, rye, oats, rice, corn and millet), where one or more herbicides of type (A) and one or more herbicides of type (B) are applied jointly or separately to the harmful plants, plant parts, plant seeds or to the area on which the plants grow, for example the area under cultivation or the pasture area.
The herbicide combinations according to the invention are used with particular preference in pasture crops, in particular grass crops, such as native perennial grass species, Brachiaria (brizantha, ruziziensis, decumbens), Panicum maximum, Cynodon plesctostachyum, Andropogum gayanus, Dichantium aristatum, Digitaria decumbens (Pangola), Panicum maximum, Medicago sativa (Alfalfa), Trifolium pratense, Trifolium repens, Melilotus officinalis, Lotus corniculatus, Lotus tenuis, Bromus unioloides, Colium spp. une, Lolium multiflorum or Lolium perenne, Festuca arundinacea, Dactylis glomerata, Phalaris bulbosa, Agropirum repens. 
The plant crops can also have been genetically modified or been obtained by mutation/selection and are preferably tolerant to acetolactate synthase (ALS) inhibitors.
The invention also relates to the use of the herbicide combinations according to the invention for controlling harmful plants, preferably in plant crops.
The herbicide combinations according to the invention can exist not only as mixed formulations of the components (A) and (B), if appropriate together with further agrochemically active compounds, additives and/or customary formulation auxiliaries, which are then applied in the customary manner, for example as a dilution with water, but also as so-called tank mixes by jointly diluting the separately formulated, or partially separately formulated, components with water.
The components (A) and (B) or their combinations can be formulated in various ways, depending on the prevailing biological and/or chemical-physical parameters. The following are examples of general possibilities for formulations: wettable powders (WP), water-soluble concentrates, emulsifiable concentrates (EC), aqueous solutions (SL), emulsions (EW) such as oil-in-water and water-in-oil emulsions, sprayable solutions or emulsions, suspension concentrates (SC), oil- or water-based dispersions, such as oil suspension concentrates (OD), suspoemulsions, dusts (DP), seed-dressing materials, granules for soil application or for broadcasting, or water-dispersible granules (WG), ULV formulations, microcapsules or waxes.
The individual formulation types are known in principle and are described for example in: Winnacker-Küchler, “Chemische Technologie”, Volume 7, C. Hanser Verlag Munich, 4th Edition, 1986; van Valkenburg, “Pesticide Formulations”, Marcel Dekker N.Y., 1973; K. Martens, “Spray Drying Handbook”, 3rd Ed. 1979, G. Goodwin Ltd. London.
The formulation auxiliaries required such as inert materials, surfactants, solvents and other additives are also known and are described, for example, in: Watkins, “Handbook of Insecticide Dust Diluents and Carriers”, 2nd Ed., Darland Books, Caldwell N.J.; H. v. Olphen, “Introduction to Clay Colloid Chemistry”; 2nd Ed., J. Wiley & Sons, N.Y. Marsden, “Solvents Guide”, 2nd Ed., Interscience, N.Y. 1950; 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, “Grenzflächenaktive Äthylenoxidaddukte” [Surface-active ethylene oxide adducts], Wiss. Verlagsgesellschaft, Stuttgart 1976, Winnacker-Küchler, “Chemische Technologie”, Volume 7, C. Hanser Verlag Munich, 4th Edition 1986.
Based on these formulations, combinations with other agrochemically active compounds, such as other herbicides, fungicides or insecticides, and with safeners, fertilizers and/or growth regulators, may also be prepared, for example in the form of a readymix or a tank mix.
Wettable powders (sprayable powders) are products which are uniformly dispersible in water and which, besides the active compound, also comprise ionic or nonionic surfactants (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyethoxylated fatty alcohols or fatty amines, alkanesulfonates or alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutylnaphthalenesulfonate or else sodium oleoylmethyltauride, in addition to a diluent or inert material.
Emulsifiable concentrates are prepared by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or else higher-boiling aromatics or hydrocarbons with addition of one or more ionic or nonionic surfactants (emulsifiers). Examples of emulsifiers which may be used are: calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters.
Dusts are obtained by grinding the active compound with finely divided solid materials, for example talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.
Suspension concentrates (SC) 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, addition of further surfactants as they have already been mentioned for example above in the case of the other formulation types.
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, further surfactants as have already been mentioned for example above in the case of the other formulation types.
Granules can be prepared either by spraying the active compound onto adsorptive, granulated inert material or by applying active compound concentrates to the surface of carriers such as sand, kaolinites or granulated inert material with the aid of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Suitable active compounds may also be granulated in the manner conventionally used for the production of fertilizer granules, if desired in a mixture with fertilizers.
As a rule, water-dispersible granules are prepared by customary processes such as spray drying, fluidized-bed granulation, disk granulation, mixing with high-speed mixers and extrusion without solid inert material. Regarding the production of disk granules, fluidized-bed granules, extruder granules and spray granules, see, for example, methods in “Spray-Drying Handbook” 3rd ed. 1979, G. Goodwin Ltd., London; J. E. Browning, “Agglomeration”, Chemical and Engineering 1967, page 147 et seq; “Perry's Chemical Engineer's Handbook”, 5th Ed., McGraw-Hill, New York 1973, pp. 8-57.
The herbicide combinations according to the invention are preferably formulated in the form of an oil suspension concentrate (OD). The oil suspension concentrates comprise, for example,

In the oil suspension concentrates according to the invention, the herbicidally active compounds a) are generally present in amounts of from 0.01 to 50% by weight, preferably from 0.1 to 30% by weight; here and in the entire description, the term “% by weight” refers, unless defined otherwise, to the relative weight of the component in question, based on the total weight of the formulation. Preferred suspended herbicides a) are (A1.1) and (A1.2), the free acids and salts of (B1), (B2), (B3) and (B4), and also (C1), (C4), (C5), (C7), (C8) and the free acids of (C2) and (C3).

The oil suspension concentrates according to the invention can be prepared by known processes, for example by mixing the components. Thus, it is possible, for example, to prepare a premix by adding any sulfosuccinate c) present and, if appropriate, further auxiliaries and additives f) to the organic solvent b). Any soluble agrochemically active compounds d) used are then dissolved in the premix. Once the dissolution process has ended, solid herbicide a) and, if appropriate, any insoluble active compounds d) used and also inorganic salts e) are suspended in the mixture. The coarse suspension is, if appropriate after pregrinding, subjected to fine grinding.
In another embodiment, solid herbicide a) and, if appropriate, any insoluble components d), e) and f) used are suspended in the organic solvent b) which optionally contains a sulfosuccinate c) and subjected to grinding. Any soluble active compounds d) used and any auxiliaries and additives f) which do not require grinding or are not required for the grinding process are added after grinding.
To prepare the mixtures, it is possible to use customary mixing apparatus which, if required, are thermostatted. For pregrinding, it is possible to use, for example, high-pressure homogenizers or mills operating by the rotor-stator principle, such as Ultraturrax homogenizers, for example those from IKA, or toothed colloid mills, for example from Puck. For fine grinding, it is possible to use, for example, bead mills which operate batchwise, for example from Drais, or bead mills which operate continuously, for example from Bachofen. The preparation process can be adapted to the properties of the components optionally pretreated and to technical and safety requirements and to economical considerations, and pregrinding and even fine grinding of the suspension may be dispensed with, if required.
The components a) to f) used for the preparation may comprise water as a minor component which is then also found in the oil suspension concentrates according to the invention. Accordingly, the oil suspension concentrates according to the invention may comprise small amounts of water, in general from 0 to 5% by weight. Preferably, the oil suspension concentrates according to the invention are not subjected to any drying.
For use, the oil suspension concentrates according to the invention may, if appropriate, be diluted in a customary manner (for example using water), to give, for example, suspensions, emulsions, suspoemulsions or solutions, preferably to give emulsions. It may be advantageous to add further agrochemically active compounds (for example tank mix partners in the form of corresponding formulations) and/or auxiliaries and additives customary for application, for example self-emulsifying oils, such as vegetable oils or paraffin oils, and/or fertilizers to obtained spray emulsions. Accordingly, the present invention also provides such herbicidal compositions based on the oil suspension concentrates according to the invention.

D. Freyer, S. A. Evans, “Weed Control Handbook”, 5th Ed., Blackwell Scientific Publications, Oxford, 1968, pages 101-103.
As a rule, the agrochemical formulations comprise from 0.1 to 99% by weight, in particular from 2 to 95% by weight, of active compounds of types (A) and/or (B), the following concentrations being customary depending on the type of formulation: In wettable powders, the active compound concentration is, for example, approximately 10 to 95% by weight, the remainder to 100% by weight being composed of customary formulation constituents. In the case of emulsifiable concentrates, the active compound concentration can, for example, amount to from 5 to 80% by weight. Formulations in the form of dusts generally comprise from 5 to 20% by weight of active compound, and sprayable solutions comprise approximately 0.2 to 25% by weight of active compound. In the case of granules such as dispersible granules, the active compound content depends partly on whether the active compound is in liquid or solid form and on the granulation auxiliaries and fillers which are being used. In the case of the water-dispersible granules, the content is generally between 10 and 90% by weight. In the case of oil suspension concentrates, the active compound concentration is generally from 0.01 to 50% by weight.
In addition, the abovementioned active compound formulations may comprise, if appropriate, the conventional adhesives, wetting agents, dispersants, emulsifiers, preservatives, antifreeze agents, solvents, fillers, colorants, carriers, antifoams, evaporation inhibitors, pH regulators or viscosity regulators.
The herbicidal action of the herbicide combinations according to the invention can be improved, for example, by surfactants, preferably by wetting agents from the group of the fatty alcohol polyglycol ethers. The fatty alcohol polyglycol ethers preferably contain 10-18 carbon atoms in the fatty alcohol radical and 2-20 ethylene oxide units in the polyglycol ether moiety. The fatty alcohol polyglycol ethers can be nonionic or ionic, for example in the form of fatty alcohol polyglycol ether sulfates, which are used, for example, as alkali metal salts (e.g. sodium salts or potassium salts) or ammonium salts, but also as alkaline earth metal salts such as magnesium salts, such as sodium C12/C14-fatty alcohol diglycol ether sulfate (Genapol® LRO, Clariant GmbH); see, for example, EP-A-0476555, EP-A-0048436, EP-A-0336151 or U.S. Pat. No. 4,400,196 and also Proc. EWRS Symp. “Factors Affecting Herbicidal Activity and Selectivity”, 227-232 (1988). Nonionic fatty alcohol polyglycol ethers are, for example, (C10-C18)-, preferably (C10-C14)-fatty alcohol polyglycol ethers containing 2-20, preferably 3-15, ethylene oxide units (e.g. isotridecyl alcohol polyglycol ether), such as Genapol® X-030, Genapol® X-060, Genapol® X-080 or Genapol® X-150 (all from Clariant GmbH). The present invention furthermore embraces the combination of compounds of the formula (I) and their salts with the wetting agents mentioned above from the group of the fatty alcohol polyglycol ethers which preferably contain 10-18 carbon atoms in the fatty alcohol radical and 2-20 ethylene oxide units in the polyglycol ether moiety and which can be present in nonionic or ionic form (for example as fatty alcohol polyglycol ether sulfates). Preference is given to C12/C14-fatty alcohol diglycol ether sulfate sodium (Genapol® LRO, Clariant GmbH) and isotridecyl alcohol polyglycol ether having 3-15 ethylene oxide units, for example from the Genapol® X series, such as Genapol® X-030, Genapol® X-060, Genapol® X-080 and Genapol® X-150 (all from Clariant GmbH). Moreover, it is known that fatty alcohol polyglycol ethers such as nonionic or ionic fatty alcohol polyglycol ethers (for example fatty alcohol polyglycol ether sulfates) are also suitable as penetrants and synergists for a number of other herbicides, inter alia also for herbicides from the group of the imidazolinones (see, for example, EP-A-0502014).
The herbicidal effect of the herbicide combinations according to the invention can also be increased using vegetable oils. The term vegetable oils is to be understood as meaning oils from oil-plant species, such as soybean oil, rapeseed oil, corn oil, sunflower oil, cottonseed oil, linseed oil, coconut oil, palm oil, safflower oil or castor oil, in particular rapeseed oil, and their transesterification products, for example alkyl esters, such as rapeseed oil methyl ester or rapeseed oil ethyl ester.
The vegetable oils are preferably esters of C10-C22-, preferably C12-C20-fatty acids. The C10-C22-fatty acid esters are, for example, esters of unsaturated or saturated C10-C22-fatty acids, in particular those with an even number of carbon atoms, for example erucic acid, lauric acid, palmitic acid and, in particular, C18-fatty acids such as stearic acid, oleic acid, linoleic acid or linolenic acid.
Examples of C10-C22-fatty acid esters are esters obtained by reacting glycerol or glycol with the C10-C22-fatty acids as they exist, for example in oils from oil-plant species, or C1-C20-alkyl-C10-C22-fatty acid esters as can be obtained, for example, by transesterification of the abovementioned glycerol- or glycol-C10-C22-fatty acid esters with C1-C20-alcohols (for example methanol, ethanol, propanol or butanol). Transesterification can be carried out by known methods as are described, for example, in Römpp Chemie Lexikon, 9th edition, volume 2, page 1343, Thieme Verlag Stuttgart.
Preferred C1-C20-alkyl-C10-C22-fatty acid esters are the methyl, ethyl, propyl, butyl, 2-ethylhexyl and dodecyl esters. Preferred glycol- and glycerol-C10-C22-fatty acid esters are the uniform or mixed glycol esters and glycerol esters of C10-C22-fatty acids, in particular those fatty acids which have an even number of carbon atoms, for example erucic acid, lauric acid, palmitic acid and, in particular, C18-fatty acids such as stearic acid, oleic acid, linoleic acid or linolenic acid.
The vegetable oils can be present in the herbicidal compositions according to the invention for example in the form of commercially available oil-containing formulation additives, in particular those based on rapeseed oil such as Hasten® (Victorian Chemical Company, Australia, hereinbelow termed Hasten, main constituent: rapeseed oil ethyl ester), Actirob®B (Novance, France, hereinbelow termed ActirobB, main constituent: rapeseed oil methyl ester), Rako-Binol® (Bayer AG, Germany, termed Rako-Binol hereinbelow, main constituent: rapeseed oil), Renol® (Stefes, Germany, termed Renol hereinbelow, vegetable oil constituent: rapeseed oil methyl ester), or Stefes Mero® (Stefes, Germany, hereinbelow termed Mero, main constituent: rapeseed oil methyl ester).
For use, the formulations, which are present in commercially available form, are optionally diluted in the customary manner, for example using water. Preparations in the form of dusts, soil granules, granules for broadcasting and sprayable solutions are usually not diluted further with other inert substances prior to use.
The active compounds can be applied to the plants, parts of the plants, seeds of the plants or the area on which the plants grow, for example the pasture area or the area under cultivation, preferably to the green plants and parts of the plants and, if appropriate, additionally to the soil.
One possible use is the joint application of the active compounds in the form of tank mixes, the concentrated formulations of the individual active compounds, in optimal formulations, jointly being mixed with water in the tank and the resulting spray mixture being applied.
A joint herbicidal formulation of the combination according to the invention of the active compounds (A) and (B) has the advantage of being easier to apply since the quantities of the components are already presented in the correct ratio to each other. Moreover, the adjuvants in the formulation can be matched optimally to each other.

B. Biological Examples

1. Herbicidal Action Against Weeds (Greenhouse Trials)

    
    


The seeds or rhizome pieces of typical harmful plants were placed into sandy loam soil in round pots, size 13, covered with soil and grown in a greenhouse under good growth conditions. After the harmful plants had emerged, they were treated, as a rule at the 2- to 3-leaf stage, with various dosages of the compositions according to the invention at a water application rate of 100 to 400 I/ha (converted).
After the treatment (approx. 4 weeks after application), the herbidical activity of the active compounds or active compound mixtures was scored visually by comparing the treated plants with untreated controls. Damage and development of all above-ground parts of the plants was recorded. Scoring was done on a percentage scale (100% action=all plants dead; 50% action=50% of the plants and green plant parts dead; 0% action=no discernible action).
The results are listed in the tables below, where the activity measured for the independent use of the active compounds (A) and (B) is stated in brackets.
