The invention relates to the technical field of plant protection products that can be used against weeds, for example, in vegetable crops and are as biologically active substances contain a combination of at least two herbicides.

From the publication of the International application WO-95/29899 known acylated aminophenylacetylene and their salts, and their use as herbicides and/or plant growth regulators. Among the compounds of this structural class of particular interest are compounds of formula (I):

where R1means a hydrogen atom or alkyl with 1-4 carbon atoms, preferably methyl or ethyl, especially methyl;

R2means a hydrogen atom or alkyl with 1-4 carbon atoms, preferably methyl or ethyl, especially methyl;

R3means a hydrogen atom, alkyl with 1-4 carbon atoms, alkoxy with 1-4 carbon atoms, allinoneruby with 2-4 carbon atoms, allinoneruby with 2-4 carbon atoms, cycloalkyl with 3-6 carbon atoms, and each of the five above-mentioned residue is not substituted or substituted by one or more residues selected from the group consisting of a halogen atom, langroup, alkoxyl with 1-4 carbon atoms and alkylsulfonyl with 1-4 carbon atoms; preferably a hydrogen atom, methyl,trifluoromethyl, ethyl, n-propyl, isopropyl, cyclopropyl, a methoxy group or ethoxypropan, preferably a hydrogen atom, a methyl or methoxy group, particularly a hydrogen atom; one of the residues X and Y means a halogen atom, alkyl with 1-4 carbon atoms, alkoxy with 1-4 carbon atoms, alkylthiols with 1-4 carbon atoms, and each of the three above-mentioned residue is not substituted or substituted by one or more residues selected from the group consisting of a halogen atom, alkoxyl with 1-4 carbon atoms and ancilliary with 1-4 carbon atoms;

and other residues X and Y denote alkyl with 1-4 carbon atoms, alkoxy with 1-4 carbon atoms or alkylthiols with 1-4 carbon atoms, and each of the three above-mentioned residue is not substituted or substituted by one or more residues selected from the group consisting of a halogen atom, alkoxyl with 1-4 carbon atoms and ancilliary with 1-4 carbon atoms; in particular X and Y respectively denote a methoxy group; and

Z means a methine group or a nitrogen atom, in particular methine group;

and their salts.

The effectiveness of these herbicides against weeds in vegetable crops is at a high level, however, depends, in General, from the norms of consumption, the corresponding preparative forms of weeds, which accordingly need to fight, or the spectrum of weeds, the cores is their and soil ratios, etc. Another criterion is the duration of, respectively, the degradation rate of the herbicide. It is necessary to consider also, if necessary, changes in the sensitivity of weeds, which may partially occur when more long-term use of herbicides or by geographic location. Loss exposure in the event of certain weeds can be compensated only relatively due to the higher consumption rates of herbicides, for example, because it often degrades the selectivity of herbicides or a higher rate of consumption does not increase. Selectivity in crops can be partially improved by additives antidotes. In General, however, there is always a need for ways of achieving herbicide action with lower consumption rates of biologically active substances. A lower rate is not only necessary for the application of the amount of biologically active substances, but, as a rule, also to the number of required auxiliary means for receiving the preparative form. Both reduces costs and improves environmental tolerance herbicide treatment.

The possibility of improving the profile of the application of herbicide may consist of a combination of biologically active substances with one or bore alkemi other biologically active substances. However, when combined application of several biologically active substances, often there are physical phenomena and biological incompatibility, such as lack of stability in the joint preparative form, the decomposition of one biologically active substance, respectively antagonism of biologically active substances. On the contrary, a desired combination of biologically active substances with a favorable profile of action, high stability and synergistically enhanced action, which reduces the rate of consumption compared to individual application of combined biologically active substances. Now unexpectedly found that biologically active substances from the group of these herbicides of the formula (I) or their salts in combination with certain different structure herbicides together are particularly favorable manner, for example when they are used in crops that are suitable for the selective application of herbicides, if necessary, with the addition of antidotes.

In particular, it should for example be mentioned of some representatives of the monocotyledonous and dicotyledonous weed flora which can be controlled using the proposed according to the invention compounds, and this is the enumeration should not be a restriction to certain species.

From monocotyledonous weed species are well covered, for example, Avena spp., Alopecurus spp., Brachiaria spp., Digitaria spp., Lolium spp., Echinochloa spp., Panicum spp., Phalaris spp., Poa spp., Setaria spp., well-covered types of Cyperus from the group of annual weeds with hand perennial species of couch-grass, Bermuda grass, Imperata and sorghum and also perennial species of Cyperus.

In the case of dicotyledonous weed species, the spectrum of action extends to species such as, for example, by annual species Abutilon spp., Amaranthus spp., Chenopodium spp., Chrysanthemum spp., Galium spp., Ipomoea 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., and in the case of perennial weeds bindweed, CIRCE, sorrel and tarragon.

If proposed according to the invention compounds applied to the soil surface before germination, either completely prevented the emergence of weeds or weeds grow up to the stage of embryonic leaf, but then their growth stops, and, finally, after three to four weeks they are completely dry. When the application of biologically active substances on the green parts of plants for post-harvest method is also very fast after treatment, there was an abrupt cessation of growth and the weeds remain available until the application stage of growth or after a certain time completely dry up so early and for a long time eliminates harmful to cultivated plants competing weeds.

Proposed according to the invention herbicide funds differ coming fast and long-lasting herbicide action. Rain resistance of biologically active substances in the proposed according to the invention combinations, generally favorable. As a special advantage is of great importance that the used in the combinations and effective dosage of the compounds (a) and (B) can be set so small that their impact on the soil is optimally low. Thus, their use becomes possible not only in sensitive crops, but also almost completely avoid groundwater contamination. Thanks proposed according to the invention a combination of biologically active substances is possible a significant reduction in the required norms of consumption of biologically active substances.

In case of joint application of herbicides of type (A)+(B) come suradditions (synergistic) effects. This action in combination stronger than the expected sum of the individual herbicides. The synergistic effects allow to reduce the consumption rate, to deal with a wide range of weeds and useless cereals, more quickly stepped herbicide action, to be more long-term continuous exposure, better control is to be weeds due to only one, accordingly, few applications, and also possible to increase the period of use. Thanks to the use of funds is also partially reduces the amount of harmful ingredients such as nitrogen or oleic acid, and their penetration into the soil.

These advantages and features required for practical weed control for the purpose of exemption of agricultural crops from unwanted competing plants and thus quantitative and qualitative ensuring and/or increasing crop yield. Thanks to these new combinations clearly exceeded the technical standard in respect of the above properties.

Although proposed according to the invention have an excellent combination herbicide activity against monocotyledonous and dicotyledonous weeds, crop plants are damaged only slightly or completely damaged.

Moreover, it is proposed according to the invention means are partly exclusive astragaloside properties in the case of cultivated plants. They are adjusting interfere with the inherent plant metabolism and thus you can use them to have an influence on metabolism in plants and for facilitating harvesting, such as, for example, by inducing desiccation and stop growth. Further, it is also suitable for the General regulation and inhibition tender is undesirable vegetative growth, without giving to the death of plants. Inhibition of vegetative growth plays an important role in many monocotyledonous and dicotyledonous crops, because in this way you can reduce or completely prevent yield losses due to lodging.

On the basis of their herbicide and regulating plant growth properties proposed according to the invention can be used for weed control in modified through genetic engineering, or obtained by mutation breeding of cultivated plants. These plants differ, as a rule, is particularly advantageous properties as resistance against herbicide funds or resistance to plant diseases or pathogens of plant diseases, as certain insects or microorganisms like fungi, bacteria or viruses. Other particular properties relate, for example, post-harvest, in respect of quantity, quality, suitability for storage, composition and special ingredients. So, for example, known transgenic plants with a high content of starch or modified as starch or transgenic plants with different fatty acid composition of the harvested crop.

The usual way of getting new plants, compared to the still existing plants have modified properties are, for example, in the class the static methods of cultivation and creation of mutants (see, for example, the U.S. patents 5162602, 4761373, 4443971). Alternative new plants with modified properties can be obtained using methods of genetic engineering (see, for example, applications for European patents 0221044, 0131624). In some cases, for example, described:

- genetically engineered changes of cultivated plants for purposes of modifying synthesized in plants starch (for example, International application WO-92/11376, WO-92/14827, WO-91/19806);

transgenic plants with endurance against other herbicides, for example against the sulfonylureas (application for European patent 0257993, application for U.S. patent 5013659);

transgenic plants with the ability to produce Bacillus thuringiensis toxins (Bt toxins)which make the plants resistant to certain pests (applications for European patents 0142924, 0193259);

transgenic plants with a modified fatty acid composition (international application WO-91/13972).

In principle, there are many molecular biology techniques, using which you can get new transgenic plants with modified properties; see, for example, Sambrook and others, "Molecular cloning", a laboratory manual, second edition. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, new York; or Winnaker "Genes and clones, VCH Weinheim, second edition, 1996, or Christou, "General trends in science is astaneh", 1, s-431 (1996).

In this genus, genetic engineering manipulations can be embedded molecules of nucleic acid in the plasmid, allowing to occur mutagenesis or change the sequence by recombination of DNA sequences. Using the above standard methods can be performed, for example, replacement of the grounds, remove partial sequence, or you can embed natural or synthetic sequences. To link the DNA fragments to each other can be attached to the fragments, adapters or linkers.

Obtain plant cells with a reduced activity produced by the gene product can be achieved, for example, by the expression of at least one corresponding antisense RNA, a single sense RNA for achieving the effect of compressie or by the expression of at least one suitably constructed ribozyme which specifically cleaves transcripts of the abovementioned produced by the gene product.

You can use DNA molecules that cover the entire coding sequence produced by the gene product, including possible flanking sequences, as well as DNA molecules, which cover only the areas of the coding sequence, and these areas should be dostat the offered length, to call in the cells of antisense effect. It is also possible the use of DNA sequences which have a high degree of homology to the coding sequences produced by the gene product, however, are not completely identical.

When the expression of nucleotide molecules in plants synthesized protein can be localized in any compartment of plant cells. However, to achieve localization in a particular compartment, for example, you can associate the coding region DNA sequences which ensure localization in a particular compartment. Such sequences are known to the expert (see, for example, Braun and others, EMBO J.11, 3219-3227 (1992); Wolter and others, Proc. Natl. Acad. Sci. USA85, 846-850 (1988); Sonnewald, etc., Plant. J.,1, 95-106 (1991)).

Transgenic plant cells can be regenerated by known technologies in whole plants. In the case of transgenic plants, in principle, we can talk about plants of any kind, that is, as monocots, and also on dicotyledonous plants. Thus obtained transgenic plants which have modified properties due to overexpression, suppression or inhibition of homologous (natural) genes or gene sequences or expression of heterologous (foreign) genes or gene sequences.

what bhakta invention further is a method of controlling undesirable plant growth, preferably in plant crops such as cereals (e.g. wheat, barley, rye, oats, rice, corn, millet), sugar beet, sugar cane, canola, cotton and soybean, particularly preferably in dicotyledonous crops as sugar beets, canola, cotton and soybean, characterized in that one or more herbicides of type (A) together with one or more herbicides of type (B) is applied to the weeds, plant parts, plant seeds or the area on which the plants are cultivated, such as crop area.

Crops can be modified by genetic engineering or can be obtained by mutation breeding and preferably tolerant to inhibitors based acetolactate (ALS-inhibitors). The object of the invention is also the use of new combinations of compounds (A)+(B) for weed control, preferably in plant crops.

Proposed according to the invention a combination of biologically active substances is possible to prepare mixed preparative forms of the two components (a) and (B), if necessary together with other biologically active agrochemical substances, additives and/or customary accessory when cooking preparative forms tools that are then applied in the usual manner once ablaut water, or as so-called tank mixes by joint dilution water separately or partially separately translated in preparative form component.

Compounds (a) and (B) or their combinations can be used for cooking preparative forms of various kinds, depending on what is provided by biological and/or physicochemical parameters. As well-known options preparative forms, for example, take into account: wettable powders, water-soluble concentrates, emulsifiable concentrates, aqueous solutions, emulsions, as emulsion, oil-in-water or water-in-oil solutions or emulsions for spraying, suspension concentrates, dispersions on an oil or water based, suspoemulsions, powdered drugs, disinfectants, granules for soil or applied by spreading or dispersible in water granulates, ultramasculine preparative form of microcapsules or waxes. Some types of preparative forms, in principle, are known and are described, for example, in the following activities: Winnaker-Küchler Chemical technology, volume 7, ed. .Hauser, Munich, fourth edition, 1986; van Valkenburg Pesticide preparations, Marcel Dekker, N.Y., 1973; K. Martens Guide "spray drying", third edition, 1979, G. Goodwin Ltd., London.

Necessary accessory made for the Oia preparative forms tools as inert materials, surfactants, solvents and other additives are also known and are described, for example, in the following activities: Watkins, "Handbook of diluents and carriers insecticidal Farrukh Dustov", second edition, Darland Books, Caldwell, new Jersey; H.v. Olphen, "Introduction to colloid chemistry of clay", second edition, J. Wiley and Sons, new York.; Marsden "Handbook of solvents", second edition, Interscience, new York, 1950; McCutcheon''s "Yearbook on detergents and emulsifiers", MC Publ. Corp., Ridegewood, new Jersey; Sisley and Wood, "encyclopedia of surface-active substances". Chem. Publ. With. Inc., New York, 1964; Schönfeldt "Surface-active ethyleneoxide adducts", Wiss. Verlasgesellschaft, Stuttgart, 1976; Winnaker-Küchler Chemical technology, volume 7, ed. .Hauser, Munich, fourth edition, 1986.

On the basis of these preparative forms can also be obtained combination with other agrochemical biologically active substances, as with other herbicides, fungicides, insecticides, and antidotes, fertilizers and/or growth regulators, for example, in the form of a finished formulation or as a tank mix. Wettable powders are uniformly dispergirujutsja in water preparations, which, together with the biologically active substance, in addition to a diluent or inert substance, also contain surfactants ionic or neion the type (wetting, dispersers), as, for example, polyethoxysiloxane ALKYLPHENOLS, polyethoxysiloxane fatty alcohols or fatty amines, alkanesulfonyl or alkylbenzenesulfonate, ligninsulfonate sodium 2,2'-di-nafcillin-6,6'-disulfonate sodium, dibutylaminoethanol sodium or ileoileostomy sodium.

Emulsifiable concentrates are obtained by dissolving the biologically active substance in an organic solvent, such as butanol, cyclohexanone, dimethylformamide, xylene or more high-boiling aromatic compounds or hydrocarbons, with the addition of one or more ionic or nonionic surfactants (emulsifiers). As emulsifiers can, for example, use: alkylarylsulfonate calcium as dodecylbenzenesulfonate calcium, or nonionic emulsifiers, as polyglycolide esters of fatty acids, simple alkylarylsulphonate esters, simple polyglycolide ethers of fatty alcohols, condensation products of propylene oxide and ethylene oxide, simple alkylpyridine, sorbitane esters of fatty acids, polyoxyethylenesorbitan esters of fatty acids or polyoxyethylenesorbitan esters.

Powdered drugs produced by milling biologically active substance with finely ground solids, as for example talc, natural clays like kaolin, bentonite and pyrophyllite, or diatomaceous earth. Suspension concentrates may be water or oil based. They can be obtained, for example, by wet grinding using a standard agitator bead mills and, if necessary, with the addition of other surfactants, which are already mentioned above in the case of other types of preparative forms.

Emulsions such as emulsions oil-in-water, it is possible to prepare, for example, by means of stirrers, colloid mills and/or static mixers using aqueous organic solvents and, if necessary, other surface-active substances already mentioned above, in the case of other types of preparative forms.

The granules can be obtained either by applying by spraying through the nozzle of the biologically active substance can adsorb granulated inert material or by applying a concentrate of biologically active substances using adhesives, such as polyvinyl alcohol, sodium polyacrylate or mineral oils, to the surface of the media as sand, kaolinites or on the surface of granulated inert material. Also suitable biologically active substances can be conventional pelletized to obtain pellets of fertilizer by the way, desirable in the case of the mixture with an application of the s.

Dispersible in water, the granules get, as a rule, conventional methods as spray drying, spray granulation in the fluidized bed, granulating plate granulator, mixing with high-speed mixers and extrusion without solid inert material. In obtaining granules plate granulator, fluidized bed, extruder and method of spraying see, for example, in a manner specified in the book "a Guide to spray drying", third edition, 1979, G. Goodwin Ltd., London; J.E.Browning "Agglomeration", Chemical and Engineering 1967, s and subsequent; Perry, "guidelines for chemical engineering", fifth edition, McGraw-Hill, new York, 1973, p.8-57.

For further details about how to obtain preparative forms of plant protection products, see, for example, G.C.Klingman "Controlling weeds as a science", John Wiley and Sons, Inc., New York, 1961, s-96; and J.D.Freyer, S.A.Evans "guidelines for the control of weeds", fifth edition, Blackwell Scientific Publications, Oxford, 1968, p.101-103.

Agrochemical formulation contain as a rule 0.1 to 99 wt.%, in particular 2-95% by weight of biologically active substances of types (a) and/or (B), and depending on the kind of preparative normal form the following concentrations: in wettable powders the concentration of the biologically active substance is, for example, about 10-95 wt.%, the remainder to 100% with the consists of the usual components of the preparative form. In emulsifiable concentrates, the concentration of biologically active substances may be, for example, 5-80 wt.%. Pulverized preparative forms often contain 5-20 wt.% biologically active substances, solutions for spraying contain approximately 0.2 to 25 wt.% biologically active substances.

In the case of granules, as dispersible granules, the content of biologically active substances depends partly on whether the active compound is liquid or solid and which is used for granulating auxiliary means and fillers. As a rule, in the case dispersible in water and granules, the content of biologically active substances is 10-90 wt.%.

Along with this, these formulations of biologically active substances, if necessary, contain respectively the usual adhesives, wetting, dispersing agents, emulsifiers, preservatives, frost protect tools and solvents, fillers, dyes and the media, antispyware, evaporation inhibitors and agents influencing the pH or viscosity.

It is known, for example, that the action of herbicides can be enhanced due to surface-active substances, preferably by wetting one of a number of alkylpolyglycoside-sulfates, which contain, for example, 10-18 carbon atoms and which is used in the form of their salts Sch is lacnych metals or ammonium, however, also in the form of magnesium salts, as alkylglycerols sodium with 12-14 carbon atoms in the alkyl part (Genapol® LRO, Hoechst); see applications for European patents 0476555, 0048436, 0336151 or application for U.S. patent 4400196, and Proc. EWRS "Factors affecting herbicide activity and selectivity", s-232 (1988). Further, it is known that alkylpolyglycoside also suitable as a support for the penetration means and amplifiers actions for a number of other herbicides, in particular also for herbicides from a number imidazolinones (see, for example, an application for a European patent 0502014).

Herbicide action can be enhanced through the use of vegetable oils. The term "vegetable oil" is understood oils from giving oil species of plants, such as soybean oil, rapeseed oil, corn germ, sunflower oil, oil of cotton seeds, linseed oil, coconut oil, palm oil, chertopolohom oil or castor oil, in particular rapeseed oil, as well as the products of interesterification, such as complex alkalemia esters as methyl esters of rapeseed oil or rapeseed oil ethyl esters of rapeseed oil.

Vegetable oils preferably are esters of fatty acids with 10 to 22 carbon atoms, preferably with 12 to 20 carbon atoms. Esters of fatty acids with 10 to 22 carbon atoms which kind of are, for example, esters of unsaturated or saturated fatty acids with 10 to 22 carbon atoms, in particular with an even number of carbon atoms as, for example, erucic acid, lauric acid, palmitic acid, and in particular of fatty acids with 18 carbon atoms, as stearic acid, oleic acid, linoleic acid or linolenic acid.

Examples of esters of fatty acids with 10 to 22 carbon atoms are esters, which are obtained by the interaction of glycerol or glycol with fatty acids with 10 to 22 carbon atoms, which contains, for example, oils from giving oil plant species, or alkalemia esters of fatty acids with 1 to 20 carbon atoms in the alkyl part and 10-22 carbon atoms in the acid part, which can be obtained, for example, by transesterification of the above glycerol or glycol esters of fatty acids with 10 to 22 carbon atoms with alcohols with 1 to 20 carbon atoms (such as methanol, ethanol, propanol or butanol). The transesterification can be performed by known methods described, for example, in "Encyclopedia of chemistry" Römpp, ninth edition, volume 2, s, ed. Thieme, Stuttgart.

As alilovic esters of fatty acids with 1 to 20 carbon atoms in the alkyl part and 10-22 carbon atoms in the acid part of the preferred methyl, ethyl, propyl, butyl, 2-telecinema and dodecylamine esters. As glycol and glycerol esters of fatty acids with 10 to 22 carbon atoms are preferred homogeneous or mixed glycol and glycerin esters of fatty acids with 10 to 22 carbon atoms, especially those fatty acids with an even number of carbon atoms as, for example, erucic acid, lauric acid, palmitic acid, and in particular of fatty acids with 18 carbon atoms, as stearic acid, oleic acid, linoleic acid or linolenic acid.

Vegetable oil may be contained in proposed according to the invention herbicide means, for example, in the form produced to the sale of oily additives preparative forms, in particular those based on rapeseed oil as Gasten® (Victorian chemical company, Australia, in the following called hasten; main component: ethyl esters of rapeseed oil), Actirob® (Nouns, France, later called actirob; main component: methyl esters of rapeseed oil), Raco-Binol® (Bayer AG, Germany, in the following called Rabinal; main component: rapeseed oil), Renol® (Stefes, Germany, in the following called renal; main component: methyl esters of rapeseed oil) or Stefes Mero® (Stefes, Germany, in the following called mero; main component: methyl esters of rapeseed what about the oil).

In accepted in trade form formulation for use, if necessary, diluted in the usual manner, for example in the case of wettable powders, emulsifiable concentrates, dispersions and dispersible in water granules with water. Powdered compositions, granules for soil, respectively, scatter the granules, as well as solutions for spraying before use, usually more is not diluted with other inert substances.

Biologically active substances can be applied to plants, plant parts, plant seeds or cultivated area (arable land), preferably to the green plants and parts of plants and, if necessary, additional arable land. One possible use is the joint application of biologically active substances in the form of tank mixes, and optimally prepared concentrated formulations of the individual biologically active substances together in the tank is mixed with water and applied the obtained working solutions. Total herbicide new form is proposed according to the invention a combination of biologically active substances (a) and (B) has the advantage of easy applicability, as the number of components already installed in the appropriate ratio to each other. In addition to the CSO, AIDS in preparative form can be optimally to pick up one after the other, while the tank mixture of different preparative forms can give undesirable combinations of excipients.

B. Biological examples

Herbicide action (field experiments)

Seeds or pieces of rhizomes typical weeds were planted and wires the Wali in the natural conditions of open ground. Processing using the proposed according to the invention of means was carried out after weed emergence is usually in stage 2 to 8 leaf in various dosages with a consumption rate of water allocation 100-400 l/ha

After application (after about 4-6 weeks after application) were visually evaluated herbicide effectiveness of biologically active substances, respectively mixtures of biologically active substances on the basis of the treated plots compared with untreated control plots. This covered the damage and the development of all above-ground parts of plants. The appraisal was carried out on a percentage scale (100% effect = the plants have died; 50% effect = 50% of plants and green parts of the plants were killed; 0% effect = no noticeable effect, as control plot). Monitorowanie values were obtained respectively at four sites. The results are given in tables 1-7, and in parentheses indicate the action in the independent application of biologically active substances (a) and (B).
