The invention relates to the field of plant protection products, which can be used for weed control in tolerant or resistant crops cereals and contain as the active herbicide components a combination of two or more herbicides. In a further concept of the cereals (grains) used in the narrow sense refers only to crops of wheat, barley, rye, oats and related special options, for example, Triticale. The concept however does not include rice or corn.

With the introduction of tolerant or resistant varieties and strains of crops, in particular transgenic varieties and strains of crops, well-known system of weed control updated with new active substances, which themselves are not selective in conventional crops. The active substances are, for example, the well-known broad spectrum herbicides, such as glyphosate, sulfosate, glufosinate, bialaphos and herbicides - derivative of imidazolinone [the herbicides (A)], which now can be used accordingly for them developed tolerant crops.

The effectiveness of these herbicides against weed plants (weeds) in a tolerant crops is at a high level, but still depends - similarly as in the processing of other g what erbicide - from the type of herbicide, its consumption rate (input quantities), the current form of the composition, the kind of eradicates weeds, climate and soil conditions, and so forth. In addition, there are cases when herbicides are weakly active (or not active) in relation to certain types of weeds. Another criterion is the duration of, respectively, the decay rate of the herbicide. In some cases it is necessary to take into account changes in the sensitivity of the weeds that may occur with long-term use of herbicides or in the case of geographical features geographical restrictions).

The loss of activity in relation to individual plants can be compensated only conditionally, if at all possible, due to large quantities of herbicides. In addition, there is always a need for methods that allow you to achieve the effectiveness of herbicides with lower quantities of active substances. When using smaller quantities reduces not only the amount of active substance required for introduction, but, as a rule, decreases the number of required auxiliary means of composition. Both factors reduce the economic costs and improve the environment when handling herbicides.

The possibility of improving the profile used is isawanya herbicide may lie in the combination of active substances with one or more other active substances, which bring the desired additional properties.

However, the combined use of multiple substances is often found on the physical and biological incompatibility, such as lack of stability of the combined composition, decomposition of the active substance or antagonism active substances. In contrast, a desired combination of active substances with a favorable profile of action, high stability and, if possible, with power due to the synergy effect, which allow reduction of the input quantities in comparison with the use of combined active substances separately.

Strikingly, it was found that the active substance from the group of the aforementioned herbicides (A) broad-spectrum in combination with other herbicides from the group (A) and, in some cases with certain herbicides (B) together are particularly favorable manner when they are used in crops that are suitable for the selective use of the first of the above herbicides.

The subject of the invention is thus the use of combinations of herbicides for weed control in crops, characterized in that an appropriate combination of herbicides contains the following components acting synergistically:

(A) gerbil is a wide spectrum from the group of compounds which consists of

(A1) compounds of formulas (A1)

where Z signifies a residue of formula HE or peptide residue of the formula-NHCH(CH3)CONHCH(CH3)COOH or

-NHCH(CH3)CONHCH (CH2CH(CH3)2]COOH, and their esters and salts, preferably glufosinate and its salts with acids and bases, specifically glufosinate ammonium, L-glufosinate and its salts, bialaphos and its salts with acids and bases, and other derivatives of phosphinotricin,

(A2) compounds of the formula (A2) and their esters and salts,

preferably glifosato and their salts with alkali metals and salts with amines, in particular of isopropylmyristate, and sulfosate,

(A3) imidazolinones, preferably of imazethapyr, imazapyr, imazamethabenz, imazamethabenz-methyl, kazahana, imazamox, imazapic (AU 263 222) and their salts, and

(A4) azoles, have a weed-killing properties, from the group of inhibitors protoporphyrinogen oxidase (PPO inhibitors), for example, WC 9717 (=CGA276854),

and

(C) one or more herbicides from the group of compounds consisting

from

(B0) one or more structurally different herbicides from the above-mentioned groups (a) and/or

(B1) herbicides acting selectively in crops,

especially against monocotyledonous weeds, with the action on Fox is Wu [deciduous actions] and/or when the soil [soil action] (residual action), and/or

(B2) herbicides acting selectively in cereals against monocotyledonous and dicotyledonous weeds, with effects primarily on the foliage, and/or

(B3) herbicides acting selectively in cereals against monocotyledonous and dicotyledonous weeds, with effect on the foliage and the effect on the soil, and/or

(B4) herbicides acting selectively in cereals against monocotyledonous and dicotyledonous weeds, with the effect on the leaves,

and crops tolerant to contained in the combinations of herbicides (a) and (b) optionally in the presence of substances that promote safety.

With structurally different herbicides from the above group (a)group (B0) are the only herbicides that are covered by the definition of the group (A), but not contained in the respective combinations as components (A).

Along with inventive combinations of herbicides that can be used and other active substances of plant protection products and excipients commonly used for plant protection, and AIDS in the compositions.

Synergic effect is observed when the joint use of active substances (a) and (b), but can still be detected when separated in time using (splitting). In the you can also make herbicides or combination of herbicides in several portions (sequential application), for example, after making up shoots should make after germination or after use in the early period after shoots should be used in middle or late period after germination. Preferred is the simultaneous introduction of active substances of the current combination, in some cases, several portions. But also separated in time making the individual active substances of the combination, and in a certain case, it can be profitable. In this system the application can also be combined (integrated) with other plant protection products such as fungicides, insecticides, acaricides and the like and/or different excipients, additives and/or fertilizers.

The synergistic effects allow to reduce the number of individual active component to increase the efficiency of actions in relation to the same kind of weed plants in the same quantities used to control not previously covered species (gaps), to extend the temporary space during the application and/or as a result of users who applies, is economically and environmentally beneficial system of weed control.

For example, thanks to the inventive combinations of (A)+(B) become possible synergistic efficiency that much and unexpected clicks the zoom superior efficiency, achieved with individual active components (a) and (B).

In the international application WO-A-98/09525 described method of weed control in transgenic crops which are resistant (stable) with respect to the phosphorus-containing herbicides, such as glufosinate or glyphosate, using a combination of herbicides that contain glufosinate or glyphosate and at least one herbicide from the group, including prosulfuron, primisulfuron, dicamba, peridot, dimethenamid, metolachlor, flumeturon, prophetarum, atrazine, clodinafop, norflurazon, ametrine is high, terbutylazine, Simazine, prometryn, NOA-402989 (3-phenyl-4-hydroxy-6-chloropyridin), the compound of the formula

where R is 4-chloro-2-fluoro-5-(methoxycarbonylmethyl)phenyl, (known from U.S. patent US-A-4671819), CGA276854=1-allyloxycarbonyl-1-metaliteracy ester 2-chloro-5-(3-methyl-2,6-dioxo-4-trifluoromethyl-3,6-dihydro-2H-pyrimidine-1-yl)benzoic acid (=WC9717 known from U.S. patent US-A-5183492) and 4-Oceanology ester 2-{N-[N-(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]aminosulfonyl}benzoic acid (known from European patent application EP-A-496701).

Details regarding possible and actual pumping effects can be found in international application WO-A-98/09525. Examples of synergistic effects, or experience in certain cultures, no, that is the same as the specific combination of the two, three or more herbicides.

From German patent application DE-A-2856260 already known some combinations of herbicides with glufosinate or L-glufosinate and other herbicides, such as aloxide, linuron, MSRA, 2,4-D, dicamba, triclopyr, 2,4,5-T, MSRV and others.

From the international application WO-A-98/08353 and European patent application EP-A 0 252 237 already known some combinations of herbicides with glufosinate or glyphosate and other herbicides from a number of sulfonylureas, such as metsulfuron-methyl, nicosulfuron, primisulfuron, rimsulfuron and so on.

The use of combinations for weed control in the literature shows only a small number of plant species or even not shown in the examples.

In our own experiments it was found that there is a strikingly large difference between the applicability of practical utility) combinations of herbicides mentioned in the international application WO-A-08/09525 and other sources, and other combinations of herbicides new type in the crops.

According to the invention available to combinations of herbicides that can be particularly advantageously used in a tolerant crops.

Compounds of the formulas (A1)-(A4) are known or can be obtained by analogy with known methods.

Formula (A1) includes the t all stereoisomers and their mixtures, in particular, the racemate, and, accordingly, the biologically active enantiomer, for example, L-glufosinate and its salts. Examples of active substances of the formula (A1) are as follows.

(A1.1) Glufosinate in the narrow sense, that is,

D, L-2-amino-4-[hydroxy(methyl)phosphinyl]butane acid,

(A1.2) Glufosinate-monoammonium salt,

(A1.3) L-Glufosinate, L - or (2S)-2-amino-4-[hydroxy(methyl)phosphinyl]-butane acid (phosphinotricin)

(A1.4) L-Glufosinate-monoammonium salt,

(A1.5) Bialaphos (or Milanapos), that is L-2-amino-4-[hydroxy(methyl)phosphinyl]-butanoyl-L-alanyl-L-alanine, in particular its sodium salt.

These herbicides (Al)-(A5) are the green parts of plants and are known as broad spectrum herbicides or total herbicides (herbicides continuous action); they are inhibitors of the enzyme glutamylcysteine in plants; see "The Pesticide Manual" 11thEdition, British Crop Protection Council 1997, p. 643-645 bzw. 120-121. In the case when the area of use in post-harvest method of combating weeds and unwanted grasses on plantations with crops and cultivated lands with the help of a special application technique also applies to struggle in rows in an agricultural field crops, such as corn, cotton, etc., increases the value of application (as) selective herbicides in resi is a competent transgenic crops. Glufosinate is used usually in the form of salts, preferably ammonium salts. The racemate glufosinate or glufosinate ammonium is usually one in dosages that are between 50 and 2000 AB/ha, mainly between 200 and 2000 g AB/ha (= Gai/ha = grams of active substance per hectare). In such dosages glufosinate is effective when it is perceived through the green parts of plants. As in soil, it is broken down with the help of microbes in a few days, then it is in the soil long enough steps. A similar situation takes place also for the applied active substance bialaphos-sodium (identical to milanapos-sodium); see "The Pesticide Manual" 11thEdition, British Crop Protection Council 1997, p. 120-121.

In the inventive combinations, as a rule, you must explicitly less of the active substance (A1), for example, the amount used may lie in the range from 20 to 800, preferably from 20 to 600 grams of the active substance glufosinate - per hectare (g AB/ha or g AI/ha). Appropriate quantities, preferably quantities calculated in mol per hectare, also suitable for glufosinate ammonium and bialaphos or bialaphos-sodium.

Combination with the existing foliage herbicides (A1) are used in a targeted way in crops that are resistant or tolerant to link the m (A1). Some tolerant crops, which are produced by gene engineering, already known and used in practice, cf. the article in the magazine "Zuckerrübe" 47. Jargang (1998, p. 217 ff; to obtain transgenic plants that are resistant against glufosinate, cf. the European patent application EP-A-0242246, EP-A-242236, EP-A-257542, EP-A-275957, EP-A-0513054).

Examples of compounds (A2) are

(A2.1) Glyphosate, N-(phosphonomethyl)glycine,

(A2.2) Glyphosate - monoisopropylamine salt,

(A2.3) Glyphosate - sodium salt,

(A2.4) Sulfosate, i.e., N-(phosphonomethyl)glycine - timesave salt = N-(phosphonomethyl)glycine-trimethylsulfoxonium salt.

Glyphosate is generally used in the form of a salt, preferably monoisopropylamine salt, or trimethylsulfoxonium salt (timesave salt = sulfosate). In the calculation of the free acid of glyphosate separate dosage lies in the area 0,050-5 kg AB/ha, mostly 0.5 to 5 kg AB/ha

Glyphosate, from the point of view of some technical aspects, similar to glufosinate, but he, in contrast to the latter, an inhibitor of the enzyme 5-enolpyruvylshikimate-3-phosphate synthase in plants; see "The Pesticide Manual" 11thEdition, British Crop Protection Council 1997, p. 646-649. In the inventive combinations of the required number to use, as a rule, lie in the range from 20 to 1000, preferably from 20 to 800 g AB/is and glyphosate.

For compounds (A2) are also already known produced by gene engineering tolerant plants (and) put into practice; cf. "Zuckerrübe" 47. Jargang (1998, p. 217 ff; cf. also the international application WO 92/00377, European patent application EP-A-115673, EP-A-409815.

In the case of the combination of compounds (A) with one or more compounds (B0) it is, according to the SNO definition, a combination of two or more compounds from group (A). Thanks to broad spectrum herbicides (A), it is assumed this combination that transgenic plants or mutants resistant in all directions in relation to various herbicides (A). Such resistance in all directions (Kreuz-resistance) already known for transgenic plants; cf. the international application WO-A-98/20144.

In addition, the claimed combination can be used together with other active substances from the group of substances that promotes safety, fungicides, insecticides and plant growth regulators or from the group of conventional plant protection additives and supplements composition. Additives are, for example, fertilizers or dyes.

For combinations of the last mentioned type with three or more active substances is also fair in the first preferred conditions, as discussed below, primarily for the inventive double combinations, as claimed double combination contained within them, and these combinations are directly related to the dual combinations.

Of special interest is also claimed the use of combinations with one herbicide from the group (A), preferably (A1.2) and (A2.2), especially (A1.2), and one or more herbicides, preferably with a single herbicide, the C group, which consists of

(B0') one or more structurally different herbicides from the above-mentioned groups (a) and/or

(B1') of herbicides acting selectively in crops, especially against monocotyledonous weeds, with leafy action and/or soil (residual action) from a group of Isoproturon, chlorotoluron, fluthiamide of prosulfocarb and/or pendimethalin, fenoxaprop-R, diclofop, tralkoxydim and flupyrsulfuron or

(B2') herbicides acting selectively in cereals against monocotyledonous and dicotyledonous weed plants, mainly deciduous action of the group AEF060 [methyl ester 4-methylsulfonylamino-2-(4,6-dimethoxypyrimidine-2-ylcarbonyl-sulfamoyl)benzoic acid], iodosulfuron and sulfosulfuron or

(B3') herbicides acting selectively in cereals against monocotyledonous and dicotyledonous weeds, with leafy action and soil by the action of the group diflufenican/flurtamone, metosulam and flumetsulam or

(B4.4') PPO-inhibitors from the group of carfentrazone, pyraflufen of fluoroglycofen and

(V') HPPDO inhibitors from the group of picolinafen, clomifene, isoxaflutole, clomazone, sulcotrione and mesotrione,

or from the herbicides of groups (B0')-(B4').

Preferred are combinations of the respective component (A) with one or more herbicides from the group (B1'), (B2'), (B3') or (B4').

Also preferred are combinations

(A)+(B1')+(B2'), (A)+(B1')+(B3'),

(A)+(B1')+(B4'), (A)+(B2')+(B3'), (A)+(B2')+(B4') or (A)+(B3')+(B4').

Some of the combinations of herbicides to be applied according to the invention, are new, mostly herbicide combinations (A)+(').

The claimed combination (= herbicide funds) are excellent herbicide action against a broad spectrum of economically important one - and dicotyledonous weeds. It is difficult eradicates perennial weeds that sprout from rhizomes, root stumps or other long-lived bodies, a well-disposed of by using active substances. This is equivalent, whether the matter before sowing to germination (during swelling) or after emergence. Preferred is the use in post-harvest method or in the early period after sowing to germination.

Separately SL is blowing to call, for example, some representatives of one - and dicotyledonous weed flora which can be controlled using the claimed compounds, the account name must not interfere with restrictions on certain types.

From monocotyledonous weeds severely affected, e.g., Alopecurus spp., Avena spp., Setaria spp., Apera spica venti, Digitaria spp., Lolium spp. and Phalaris spp., and Brachilisia spp., Brachiaria spp., Panicum spp., Agropyron spp., species of wild cereals. Sorghum spp., Echinochloa spp., Cynodon spp., Poa spp., and also species of Cyperus and Imperata.

For dicotyledonous weeds spectrum of action extends to species such as Chenopodium spp., Marticaria spp., Amaranthus spp., Ambrosia spp., Galium spp., Emex spp., Lamium spp., Papaver spp., Solanum spp., Cirsium spp., Veronica spp., Anthemis spp., Abutilon spp., Polygonum spp., Stellaria spp., Kochia spp. and Viola spp. Strongly affected also Datura spp., Chrysanthemum spp., Thiaspi spp., Pharbitis spp., Ipomoea spp., Sida spp., Sinapis spp., Cupsella spp., Xanthium spp., Convolvulus, Rumex and Artemisia.

If the claimed compounds are made before germination on the soil surface, or seedlings germinating weeds completely suppressed, or the weeds grow to the stage of sprouting leaf, but then still stop in its growth and, eventually, completely disappear after three to four weeks.

When applying the active compounds in green parts of plants according to post-harvest method is also very fast after processing comes to an abrupt stop growth, and weed plants stop what I growth stage, located at the point corresponding to the time of application, and after a certain time completely die off, and thus the competition of weeds, harmful to cultivated plants, is eliminated very early and for a long time.

The inventive herbicide funds, in comparison with individual drugs differ coming faster and longer continued herbicide action. The stability of the active substances to the rain in the inventive combinations, as a rule, is sufficient. Particularly advantageous is the gain in weight: efficient and used in combination, the dosage of the compounds (a) and (b) can be set sufficiently small, and their effect on soil optimally. Thus their application is possible not only in sensitive crops, but combinations based on the water, in practice, should be avoided. Due to the inventive combinations of active substances creates the possibility to reduce the required applied quantities of active substances.

In case of joint application of herbicides of type (A)+(B) is coradditional effect (synergistic effect = synergism). The effectiveness of the combination is higher than the efficiency of the expected total effect of individual herbicides.

The synergistic effects allow to reduce the applied amount, to combat a wide JV is CDROM weeds and grasses, create the opportunity for a more rapid onset and more prolonged action of herbicides, help to strengthen the control of weeds with only one or fewer incorporations, as well as allow you to extend the time frame possible use. Partly due to the use of funds in crops reduces the amount of harmful ingredients, such as nitrogen or butyric acid.

Named properties and benefits needed in practical weed control, in order to release the crops from unwanted competitive plants and thereby quantitatively and qualitatively to ensure the harvest at the proper level and/or to improve it. Because of those new combinations clearly exceeded standards technical standards related to the described properties.

Despite the fact that the claimed compounds exhibit excellent herbicide activity in relation to one - and dicotyledonous weeds, tolerant or Kreuz-tolerant crops such as wheat, rye, barley, oats and specific culture, for example, Triticale are damaged only to a minor extent or not at all damaged.

Moreover, the proposed drug partly show excellent properties in the regulation of growth in cereal crops. They regulate the way mesilau is to own the metabolism of plants and can be used thereby to separate the influence on the part of the plant. In addition, they are also suitable for the General control and inhibition of unwanted vegetative growth, without having to die out plants. Inhibition of vegetative growth plays an important role in many one - and dicotyledonous crops since the growth can be reduced or can be completely prevented.

On the basis of their herbicide and regulating plant growth properties of the tools used to combat harmful plants in tolerant known or Kreuz-tolerant cereal crops or even undeveloped tolerant or genetically modified cereal crops. Transgenic plants, as a rule, have particularly advantageous properties, in addition to resistance in relation to the claimed means, they have, for example, resistance against plant diseases or pathogens of plant diseases such as certain insecticides or microorganisms such as fungi, bacteria or viruses. Other distinguishing characteristics include, for example, to the fruits (crop) to their quantity, quality, capacity for storing, composition and special ingredients. For example, the famous transgenic plants with high oil content or higher quality, for example, with a different composition of fatty acids in the fruit.

The usual way of getting new plants which, in comparison to the previously known have modified properties is, for example, in the classical way of breeding and production of mutants. Alternative new plants with modified properties can be derived using a gene engineering method (see, for example, European patent application EP-A-0221044, EP-A-0131624). In many cases, are described, for example,

gene-engineering change crops for modification synthesized in plants starch (for example, international application WO 92/11376, WO 92/14827, WO 91/19806),

transgenic culture of plants which are resistant to other herbicides, for example, sulfonylurea (European patent application EP-A-0257993, U.S. patent US-A-5013659),

transgenic plant cultures with the ability to produce the Thuringian toxins (Bt toxins)which make the plants resistant to certain pests (European patent application EP-A-0142924, EP-A-0193259),

transgenic culture plant with modified fatty acid composition (international application WO 91/13972).

Numerous molecular biological technologies with which can be obtained new transgenic plants with modified properties, in principle known; see, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2. Aufl. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY; or Winnacker "Gene und Klone", VCH Weineim 2. Edition 1996 or Christou. "Trends in Plant Science" 1 (1996) 423-431).

For such gene manipulations molecules of nucleic acids can be incorporated into plasmids, which allow mutagenesis or changing sequences due to recombination of DNA sequences. Using the above standard methods can occur, for example, exchanges bases can be deleted parts of the sequences are added or natural or synthetic sequences. To link the DNA fragments to each other by fragments can be attached adapters or linkers.

Obtaining plant cells with a reduced activity of geneproduct can be achieved, for example, by the expression of at least one corresponding antisense RNA, a single sense RNA for achieving compressive effect or the expression of at least one suitably constructed ribosomes, which specifically cleaves transcripts of the abovementioned geneproduct.

This can be used in DNA molecules, which include the total coding sequence of geneproduct, including accidentally present flanking sequences, and DNA molecules which comprise only part of the coding sequence, these parts must be long enough for the button to call in the cells of antisense effect (antisense effect). It is also possible to use DNA sequences that have a high degree of gomologichnosti to coding sequences geneproduct, but not identical.

When the expression of nucleic acid molecules in plants are synthesized protein can be localized in any compartment. In order to achieve localization in a particular compartment, coding sequences can be linked, for example, to DNA sequences which ensure localization in a particular compartment. Such sequences are known 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).

Transgenic plant cells can be regenerated by known technologies in whole plants. When transgenic plants we can talk principally about the plants of any kind, that is, as monocots and dicots.

Thus, it can be obtained transgenic plants which exhibit modified properties due to over-expression, suppression or inhibition of homologous (= natural) genes or gene sequences or expression of heterologous (= foreign) genes or gene sequences.

In connection with this object of the invention is also a method of controlling undesirable growth is astani in tolerant crops, characterized in that one or more herbicides of type (A) with one or more herbicides of type (B) is applied on plants, parts of plants or cultivated surface.

The subject invention are also new combinations of compounds (A)+(b) and herbicide products containing these combinations.

The claimed combination of active substances can be as well as mixed formulations of the two components, in some cases with other active substances, additives and/or auxiliary means of composition, these mixed groups then the usual way is diluted with water and used, or claimed combinations are made in the form of so-called tank (tanker) mixtures by the total dilution of the separately compiled or partially separately prepared component.

Compounds (a) and (b), or combinations thereof, can be prepared in various ways, depending on what biological or physico-chemical parameters specified. As a General opportunities for (species) composition are considered, for example: powder for spraying (WP), emulsifiable concentrates (EC), aqueous solutions (SL), emulsions (EW)such as emulsion, oil-in-water” or “water in oil”spray solutions or emulsions, dispersions on an oil or water based, subpoenas and, powder (dust) means (DP), etching tools, granules for soil or for spilling or dispersible in water pellets (WP), ULV formulations, microcapsules or waxes.

Specific types of compositions in principle known and described, for example, in:

Winnacker-Küchler, "Chemische Technologie", Band 7, C.Hauser Verlag München, 4. Aufl. 1986; van Valkenburg, "Pesticide Formulations", Marcel Dekker N.Y., 1973; K.Martens, "Spray Drying Handbook", 3rdEd. 1979, G.Goodwin Ltd. London.

Tools needed compounds, such as inert materials, surfactants, solvents and other additives are also known and described, for example, in Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2ndEd., Darland Books, Caldwell N.J.; H.v.Olphen, "Introduction to Clay Colloid Chemistry", 2ndEd., J.Wiley & Sons, N.Y.Marsden, "Solvent guide", 2ndEd., Interscience, N.Y. 1950; McCutcheon''s, "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridegewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem.Publ. Co. Inc., N.Y. 1964; Schönfeldt, "Grenzflåchenaktive åthylenoxidaddukte", Wiss. Verlagsgesellschaft, Stuttgard 1976,in: Winnacker-Küchler, "Chemische Technologie", Band 7, C.Hauser Verlag München, 4. Aufl. 1986.

Based on the above formulations may be obtained as a combination with other substances having pesticidal activity, such as other herbicides, fungicides or insecticides, as well as substances that promote conservation, fertilizers and/or plant growth regulators, for example, in the form of a solid composition.

P the Rosca for spraying (wettable powders) are uniformly dispersible in water preparations which, together with the active substance, in addition to the diluent and inert substance, also contain surfactants of ionic and nonionic type (wetting and dispersing agents), for example, polyoxyethylene ALKYLPHENOLS, polyoxyethylene fatty alcohols or fatty amines, alkanesulfonyl or alkylbenzenesulfonate, sodium salt of a lignin-sulfonic acids, sodium salt of 2,2'-dynafilter-6,6'-disulfonate or oleoylethanolamide sodium.

Emulsifiable concentrates are obtained by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or in high-boiling aromatic compounds or hydrocarbons with the addition of one or more ionic or nonionic surfactants (emulsifiers). As emulsifiers can be used, for example: calcium salts of alkylarylsulfonates, such as calcium-dodecylbenzenesulfonate, or nonionic emulsifiers, such as polyglycolide esters of fatty acids, alkyldiphenylamine esters, polyglycolide ethers of fatty alcohols, condensation products of mixtures of propylene oxide-ethylene oxide, allylprodine esters, ethers, sorbitan-fatty acids, esters of polyoxyethylenesorbitan-fatty acids or polyoxyethylene esters sorbitan.

Powder the funds can be obtained by grinding the active substance with finely ground solids, for example talc, natural clays such as kaolin, bentonite and pyrophyllites, or hard-shelled land.

The granules can be obtained either by spraying the active substance through the nozzle on capable of adsorption of granulated inert material or by applying concentrates of active substances by means of adhesive means, for example, polyvinyl alcohol, sodium salt of polyacrylic acid, or also with the help of mineral oils on the surface of carriers such as sand, kaolinites or on the surface of granulated inert material. Suitable active substances can also be granulated normal fertilizer granules way - optionally in a mixture with fertilizers. Dispersible in water, the granules get, as a rule, by the method, for example, spray drying, granulation in the vortex layer, disk granulation, mixing in high-speed mixers and extrusion without solid inert material.

Agrochemical compositions contain, as a rule, from 0.1 to 99 wt.%, in particular from 2 to 95 wt.%, active substances of types a and/or depending on the type of composition usually used concentration.

In powders for spraying the concentration of the active substances is, for example, from about 10 to 95 wt.%, the remainder to 100 wt.% consists of the usual comp the element composition. In the case of emulsifiable concentrates, the concentration of active substances may be, for example, from 5 to 80 wt.%. Powder formulations contain the majority of from 5 to 20 wt.% the active substance, spray solutions of from about 0.2 to 25 wt.% the active substance.

In the case of granules, such as dispersible granules, the active substance depends on whether the active compound is in liquid or solid form and what granulating means and fillers are used. Typically, dispersible in water and granules, the active substance is between 10 and 90 wt.%.

Along with this, these formulations with the active substances in some cases contain the current conventional way of improving adhesion, wetting and dispersing funds, emulsifiers, preservatives, tools, protect from freezing, and solvents, fillers, dyes and the media, antispyware, substances that prevent evaporation, and tools that affect the pH value and viscosity.

For example, it is known that the action of glufosinate ammonium (A1.2), and L-enantiomers, may be more effective due to surface-active substances, preferably by wetting from a number of sulfates alkylpolyglycoside esters, which contain, for example, from 10 to 18 carbon atoms, and COI is lesuuda in the form of their salts with alkali metals or ammonium salts, and also in the form of magnesium salts such as sodium salts of sulfates of mixed esters of fatty alcohols with diglycolate (®Genapol LRO, Hoechst); see European patent application EP-A-0476555, EP-A-0336151 or US-A-4 400 196, and Proc. EWRS Symp. "Factors Affecting Herbicidal Activity and selectivity values", 227-232 (1988). In addition, it is known that sulfates alkylpolyglycoside esters, as well as a means of facilitating penetration, and substances that enhance the action, suitable for a number of other herbicides, among other things, to herbicides from a number imidazolinones, see European patent application EP-A-0502014.

For the application of a usual form presents compositions in some cases diluted in the usual manner, for example, in the case of powders for spraying, emulsifiable concentrates, dispersions and dispersible in water granules with the water. Powdered formulations, granules applied to the soil, and their broken pellets and spray solutions are usually not diluted more before using other inert substances.

The active substance can be applied to plants, plant parts, plant seeds or the cultivated area (arable land), preferably to the green plants or parts of plants, and in some cases additional arable land.

Can also be used, which provides for the joint and the use of active substances in the form of tank mixes, optimally prepared concentrated formulations of the individual active substances are mixed together in a vessel with water, and the resulting mixture for spraying is used as a herbicide agent.

Total herbicide composition of the claimed combinations of the individual active substances (a) and (b) has an advantage from the standpoint of ease of use as the number of components are already in the correct ratio to each other. In addition, aid in the composition matched to each other, while the tank mixture of different compositions may contain unwanted combination of excipients.

Biological examples

1. The effect on the weeds to sprout

Seeds or shoots rhizomes one - and dicotyledonous weed plants are planted in cardboard pots in sandy loam soil and covered with earth. Funds previously prepared in the form of concentrated aqueous solutions, wettable powders or concentrates, emulsions, put then in the form of an aqueous solution, suspension or emulsion in water, which amount is taken from the calculation of 600-800 l/ha, in various dosages on the surface of the earth. After treatment, the pots set in a greenhouse and kept under favorable for weed growth conditions. Visual observation of the damage plants or shoots (shoots) is performed after germination of the test plants 3-4 weeks after the start of the experiment in comparison with untreated control plants. As the results of observations, the proposed drug exhibit high herbicide efficacy in pre-emergence period against the Oia to a broad spectrum of weed grasses and herbs.

Often for the claimed combinations are observed efficiency that exceed the formal sum of the efficiencies in the application of herbicides separately ( = synergistic effect).

When the observed values of efficiency superior to the formal sum of the values in experiments in which the active substance is applied separately, then they also surpass the expected value for Colby, which is calculated by the following formula and is also seen as evidence of synergism (cf. S.R.Colby, Weeds 15 (1967) S.20-22):

E=a+b-(A·/100)

They have used the notation: a, b = Efficiency of active substances And, accordingly, in% (separate experiments) a or b in g AB/ha

The observed values in experiments indicate that with suitable low doses, the effectiveness of combinations lies above the expected values for Colby.

2. The effect on the weeds in the post-harvest period

Seeds or shoots rhizomes one - and dicotyledonous weed plants are planted in cardboard pots in sandy loam soil, land cover and germinated in the greenhouse in favourable growth conditions. Three weeks after planting, the experimental plants at the stage of the third sheet is treated with the claimed means. The proposed drug prepared in the form of powders for spraying or concentrates of emulsions, the different dosages sprinkle with water, the number which is taken from the calculation of 600-800 l/ha, the green parts of plants. Approximately 3-4 weeks after time of test plants in the greenhouse under optimal growth conditions, the effect of the drugs assessed visually in comparison with untreated control plants. The proposed drug in the post-harvest period also exhibit high herbicide activity against a broad spectrum of economically important weed grasses and weeds.

It is often observed the effectiveness of the proposed combinations that exceed the formal sum of the efficiencies in the application of herbicides separately.

The observed values in experiments indicate that with suitable low doses of the effectiveness of combinations lie above the expected values for Colby (cf. the evaluation in example 1).

3. Herbicide action and compatibility with crop plants (field experience)

Plants transgenic crops resistant (resistance) in relation to one or more herbicides (A), were grown together with typical weed plants in the open ground on parcels 2×5 m in the natural conditions of open ground; alternative when growing plants, crops were established natural overgrowing weeds. The processing of the inventive means and the Department is but the processing in the control experiment using only one component is active substances produced in parallel under standard conditions, with the help of a special device for spraying (parcels) at the rate of 200-300 litres of water per hectare, according to the scheme of table 1, i.e. in the periods before sowing to germination after sowing to germination or after the emergence of the early, middle or late stage.

With intervals of 2, 4, 6 and 8 weeks after making herbicide effectiveness of the active substances or mixtures of active substances was evaluated visually on the treated parcels in comparison with control untreated parcels. Taking into account the damage and the development of all above-ground parts of plants. Assessment of proizvodili on a percentage scale (100% efficiency = all plants died;

50% efficiency = 50% of plants and green parts of the plants died;

0% efficiency = no noticeable action = like control parcels).

In each case were averaged estimates on 4 parcels.

The comparison showed that the proposed combination in most cases show much, and in some cases much greater efficiency than the sum of the efficacies of the individual herbicides (EAnd). Efficiency for significant periods of time observations lie above the expected values for Colby (EWith)[cf. explanations in example 1] and indicate so on the synergies. Plants of cereals, in contrast, due to processing are not damaged or slightly damaged.
