Description:
This application has been filed under 35 U.S.C. 371 as the national stage of international application PCT/EP97/04947 filed Sep. 10, 1997. 
    
    
     TECHNICAL FIELD OF THE INVENTION 
     The invention relates to novel herbicidal synergistic active compound combinations comprising, on the one hand, known arylsulphonylaminocarbonyltriazolinones and, on the other hand, known herbicidally active compounds, which can be used particularly successfully for selectively controlling weeds in a variety of crops of useful plants. 
     BACKGROUND OF THE INVENTION 
     Sulphonylaminocarbonyltriazolinones, which are herbicides having a broad spectrum of action, are the subject of a series of patent applications (cf. EP 341489, EP 422469, EP 425948, EP 431291, EP 507171, EP 534266, WO 96/11188, DE 19508118). However, the known sulphonylaminocarbonyltriazolinones have a number of gaps in their action. 
     Surprisingly, it has now been found that a number of known active compounds from the series of the arylsulphonylaminocarbonyltriazolinones, when used together with known herbicidally active compounds from various substance classes, exhibit pronounced synergistic effects with regard to the activity against weeds and can be used particularly advantageously as broad-spectrum combination preparations for the selective control of weeds in crops of useful plants, such as, for example, wheat.

     Mixing components of the formula (I) which may be particularly emphasized are the compounds 2-(2-methoxycarbonyl-phenylsulphonylaminocarbonyl)-4-methyl-5-n-propoxy-2,4-dihydro-3H-1,2,4-triazol-3-one (I-1) and 2-(2-trifluoromethoxy-phenylsulphonylaminocarbonyl)-4-methyl-5-methoxy-2,4-dihydro-3H-1,2,4-triazol-3-one (I-2) and their sodium salts (I-1, Na salt), (I-2, Na salt). 
     The compounds of the formula (I) are described in the abovementioned patent applications or patent specifications. 
     Mixing components from the active compounds of Group 2 which may be particularly emphasized are: 
     amidosulfuron, bentazon, bromoxynil, carfentrazone(-ethyl), clodinafop(-propargyl), clopyralid, chlorsulfuron, chlortoluron, cyclosulfamuron, 2,4-D, diclofop(-methyl), difenzoquat, diflufenican, DPX-KE459, ET-751, ethoxyfen, fenoxaprop(-ethyl), fluoroglycofen(-ethyl), flupropacil, fluroxypyr, isoproturon, mecoprop, metosulam, metribuzin, metsulfuron(-methyl), pendimethalin, prosulfocarb, pyridate, sulfosulfuron, thifensulfuron(-methyl), tralkoxydim, triasulfuron, tribenuron(-methyl) or trifluralin. 
     From this group, metribuzin is of very particular interest as a mixing component. 
     Surprisingly, it has now been found that the above-described active compound combinations of the arylsulphonylaminocarbonyltriaozolinones of the formula (I) and the abovementioned active compounds of Group 2, in addition to being very well tolerated by useful plants, have particularly high herbicidal activity and can be used in a variety of crops, in particular in wheat, but additionally also in maize, barley and rice, for the selective control of weeds. 
     Surprisingly, the herbicidal activity of the active compound combinations according to the invention of compounds of the abovementioned groups 1 and 2 is considerably higher than the sum of the effects of the individual compounds. 
     This means that there exists not only a complementary action but also an unforeseeable synergistic effect. The novel active compound combinations are tolerated well by a large number of crops, and the novel active compound combinations also effectively control weeds which are otherwise difficult to control. The novel active compound combinations are therefore a valuable addition to the selective herbicides. 
     The active compound combinations according to the invention can be used, for example, in connection with the following plants: 
     Dicotyledonous weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum. 
     Dicotyledonous crops of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita. 
     Monocotyledonous weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus, Apera and Phalaris. 
     Monocotyledonous crops of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium. 
     However, the use of the active compound combinations according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants. 
     At specific concentration ratios, the synergistic effect of the active compound combinations according to the invention is particularly pronounced. However, the ratios by weight of the active compounds in the active compound combinations can be varied within relatively wide ranges. In general, 0.01 to 1000 parts by weight, preferably 0.05 to 500 parts by weight and particularly preferably 0.1 to 100 parts by weight of active compound of Group 2 are used per part by weight of active compound of the formula (I). 
     The active compound combinations can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspo-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances. 
     These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents. 
     If the extender used is water it is also possible to use, for example, organic solvents as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, as well as water. 
     As solid carriers there are suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as protein hydrolysates; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose. 
     Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils. 
     It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc. 
     The formulations in general comprise between 0.1 and 95 per cent by weight, preferably between 0.5 and 90%, of active compounds. 
     In general, the active compound combinations according to the invention are applied in the form of ready mixes. However, the active compounds which the active compound combinations comprise can also be formulated individually and mixed upon use, i.e. applied in the form of tank mixes. 
     The novel active compound combinations can be used as such or in the form of their formulations, and furthermore also as mixtures with other known herbicides, ready mixes or tank mixes again being possible. They may also be mixed with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellents, growth substances, plant nutrients and agents which improve soil structure. For particular application purposes, in particular when applied post-emergence, it may furthermore be advantageous to incorporate, in the formulations, mineral or vegetable oils which are tolerated by plants (for example the commercial product “Oleo DuPont 11E”) or ammonium salts such as, for example, ammonium sulphate or ammonium thiocyanate, as further additives. 
     The novel active compound combinations can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomizing, dusting or scattering. 
     The active compound combinations according to the invention can be applied before and after the plants have emerged, that is to say pre-emergence and post-emergence. They can also be incorporated into the soil before sowing. 
     The good herbicidal activity of the novel active compound combinations can be seen from the examples which follow. While the individual active compounds show weak points regarding the herbicidal activity, the combinations, without exception, display a very good activity against weeds, which exceeds a simple additive effect. 
     A synergistic effect in herbicides is always present when the herbicidal activity of the active compound combination exceeds the activity of the active compounds when applied individually. 
     The expected activity for a given combination of two herbicides can be calculated as follows (cf. COLBY, S. R.: “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, pages 20-22, 1967): 
     If X=% damage caused by herbicide A (active compound of the formula I) at application rate of p kg/ha 
     and Y=% damage caused by herbicide B (active compound of the formula II) at application rate of q kg/ha 
     and E=the expected damage of herbicides A and B at application rates of p and q kg/ha, 
     then E=X+Y−(X*Y/100). 
     If the actual damage exceeds the calculated figure, the activity of the combination is superadditive, i.e. it shows a synergistic effect. 
     It can be seen from the examples which follow that the observed herbicidal activity of the active compound combinations according to the invention in the weeds exceeds the calculated activity, i.e. that the novel active compound combinations act synergistically. 
    
    
     EXAMPLE A 
     Post-emergence Test 
     Solvent: 5 parts by weight of acetone 
     Emulsifier: 1 part by weight of alkylaryl polyglycol ether 
     To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration. 
     Test plants of a height of 5-15 cm are sprayed with the preparation of active compound such that the particular desired amounts of active compound are applied per unit area. The concentration of the spray liquor is chosen such that the particular desired amounts of active compound are applied in 1000 l of water/ha. After three weeks, the degree of damage to the plants is rated visually in % damage in comparison to the development of the untreated control. 
     The figures denote: 
     0%=no effect (like untreated control) 
     100%=total destruction.
