Description

The invention relates to herbicides that can be used for weed control in vegetable crops, and more particularly to a synergistic combination of herbicides and method of weed control.

From international application WO 95/M29899 known acylated aminophenylacetylene and their salts, and their use as herbicides and/or plant growth regulators. Of compounds such structures are of most interest are the compounds of formula (X) and their salts

in which R1is hydrogen or alkyl containing 1-4 carbon atoms, preferably the stands or ethyl, most preferably the stands,

R2is hydrogen or alkyl containing 1-4 carbon atoms, preferably the stands or ethyl, most preferably the stands,

R3is hydrogen, alkyl containing 1-4 carbon atoms, alkoxy containing 1-4 carbon atoms, alkanox containing 2-4 carbon atoms, alkyloxy containing 2-4 carbon atoms, cycloalkyl containing 3-6 carbon atoms, and each of the five last mentioned radicals are not substituted or substituted by one or more radicals from the group halogen, cyano, alkoxy containing 1-4 carbon atoms, and alkylsulfonyl containing 1-4 and the Ohm carbon, preferably is hydrogen, stands, trifluoromethyl, ethyl, n-propylene, isopropyl, cyclopropyl, methoxy or ethoxy, preferably hydrogen, stands or methoxy, most preferably hydrogen, one of the radicals X and Y is halogen, alkyl containing 1-4 carbon atoms, alkoxy containing 1-4 carbon atoms, alkylthio containing 1-4 carbon atoms, and each of the three last mentioned radicals are not substituted or substituted by one or more radicals from the group halogen, alkoxy containing 1-4 carbon atoms, and alkylthio containing 1-4 carbon atoms and the other of radicals X and Y is alkyl containing 1-4 carbon atoms, alkoxy containing 1-4 carbon atoms, or alkylthio containing 1-4 carbon atoms, and each of the three last mentioned radicals are not substituted or substituted by one or more radicals from the group halogen, alkoxy containing 1-4 carbon atoms, and alkylthio containing 1-4 carbon atoms, preferably X and Y are methoxy group, and Z is CH or N, preferably CH, and their salts.

The action of these herbicides against weeds in vegetable crops is at a high level, however, usually depends on the rates of consumption of herbicides, type of formulation, from destroying weeds or spectrum of weeds, climatic conditions and the condition p is CVI. Another criterion for evaluation of herbicides is the duration or rate of decomposition of herbicides. In this case also accepted changes in susceptibility of weeds, which can limit the effects of herbicides during prolonged use or for geographical reasons. The loss of activity when exposed to individual plants can only conditionally to offset the higher rate of application, for example, because the application of higher standards of consumption, often deteriorating the selectivity of herbicides or do not occur at the same time improve the activity. Partly selectivity of crops can be improved by the addition of protective substances. However, there is always a need for methods by which a herbicide action is achieved at a lower rate of application of active substances. Lower the consumption rate of the active substance reduces not only the flow required to introduce and, as a rule, the flow rate required preparative additives. All this reduces the economic costs and improve the environmental compatibility of the herbicide treatment.

The possibility of improving spectrum herbicide application may consist of a combination of active substances with one or more other active substances that enhance wish the additional properties. However, the combined use of several active substances often possible physical and biological incompatibility, such as lack of stability in the combined preparative form, decomposition of the active substances or antagonism active substances. So desirable are the combination of active substances with favorable spectrum of activity, high stability and enhanced by the synergistic action that contributes to the reduction in the rate of consumption compared to separately entered combine active substances.

The closest analogue of the invention is described in the application DE No. 19520839 A1 synergistic combination of herbicides containing 4-iodine-2-[3-(methoxy-6-methyl-1,3,5-triazine-2-yl)aridoculture]benzoic acid (iodosulfuron-methyl) or its salt and N-[N-4,6-dimethoxypyrimidine-2-yl)-amino-carbonyl]-2-(dimethylaminoethyl)-5-amino (or formylmethionine)-benzosulfimide.

Additives are, for example, fertilizers, and dyes.

We offer a synergistic combination shows excellent herbicide activity against a broad spectrum of economically important monocotyledonous and dicotyledonous weed rastenyte active substances are suitable for combating perennial weeds, which shoots forth from seeds, rhizomes, etc. In this way the introduction of the proposed combination does not play any role: before sowing of the plants, before emergent or post-emergent plants. Preferred is the introduction of post-emergent plants or immediately after sowing before the shoot of the plants.

In particular, for example, the following are named as examples of some representatives of the weeds of the family of monocotyledonous and dicotyledonous plants, which can be controlled by the proposed connections, while this cannot be considered as a restriction on certain types.

Weeds families of monocots are, for example, oats, Alopecurus, brachiaria, weed, ryegrass, barnyard grass, millet, reed Canary grass, bluegrass, spickle, as well as certain types of site; perennial monocotyledonous species in the family are, for example, wheat grass, cynodon and sorghum, and certain types of site.

In dicotyledonous weeds action spectrum offer synergistic combination of herbicides extends to species such as, for example, abutilon, amaranth, pigweed, chrysanthemum, Galium, morning glory, Kochia, dead-nettle, Matricaria, morning glory purple, Highlander, sid, mustard, nightshade, starwort, Veronica, violet, cocklebur, and perennial species, for example, bindweed, Thistle, sorrel and tarragon.

We offer a synergistic combination of gerbil is s applied to the soil surface before germination of plants, thus fully reduce the germination of weeds, or weeds grow to the stage of emergence of leaves, but then their growth stops and they completely disappear in 3-4 weeks.

When applying the active compounds in green parts of plants after germination also very quickly comes characterized by cessation of growth, and stop weeds growth stage at the time of processing, or die after a certain time, so the weeds that are harmful to cultivated plants, is eliminated at a very early stage and for a long time.

We offer a synergistic combination of different fast and long-lasting herbicide action. The active substance in the composition, generally, is resistant to rain. A significant advantage lies in the possibility of using the dosage used in the compositions of the compounds (a) and (B) is so small that their effect on the soil is optimally low. Therefore, it becomes possible not only the use of the proposed compounds in sensitive crops, but also virtually eliminates contamination of the groundwater.

This synergistic combination is possible a significant reduction in the required norms of consumption of active substances.

When sharing herbicides of type (is) + (B) is sverhsummarny (= synergistic) effects. The effect of herbicides in the compositions is more effective than the sum of the actions of individual herbicides. A synergistic effect contributes to the reduction in the rate of consumption, against a broad spectrum of weeds and weed grasses, fast herbicide action, lasting effect, improved control of weeds in one or a few treatments, and expanding the field of potential use. Partly due to the use of the proposed combination to reduce the amount of harmful components such as nitrogen and oil acids, and their introduction into the soil.

Named properties and benefits necessary for practical weed control to protect crops from unwanted plants, however, quantitatively and qualitatively to ensure and/or improve productivity. Describes the properties of these new compositions significantly exceed the known technical standards.

Despite the fact that the proposed combination of herbicides shows high herbicide activity against monocotyledonous and dicotyledonous weeds, it is almost impossible to damage cultivated plants.

Due to its weed-killing properties of the proposed combination can be used for weed control in developing or more genetically modified plant to the cult of the Ah. Transgenic plants along with durability to offer synergistic combinations differ, as a rule, is particularly advantageous properties, for example resistance to plant diseases or pathogens of plant diseases, such as certain insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate to crop production, for example regarding the quantity, quality, suitability for storage, composition and special ingredients. For example, the famous transgenic plants with a high content of starch or modified as starch, or plants with different fatty acid composition of plant products.

Traditional methods of obtaining new plants, compared to the so far obtained cultures have modified properties are, for example, in the classical methods of cultivation and obtaining mutants. Alternatively you can obtain new crops with modified properties when using genetic engineering techniques (see applications for European patents EP-A-0221044, EP-A-0131624). For example, describe a few possible options:

- genetically engineered changes of cultivated plants with the purpose of modifying the starch synthesized in the plants (see international application WO 92/11376, WO 92/14827, WO 91/19806),

- transgenically plants, which are resistant to other herbicides such as sulfonylureas (see the application for the European patent EP-A-0257993, the U.S. patent And 5013659), transgenic plants with the ability to produce Bacillus thuringiensis toxins (Bt toxins)which make the plants resistant to certain pests (see applications for European patents EP-A-0142924, EP-A-0193259),

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

Numerous molecular biology techniques, using which it is possible to obtain transgenic plants with modified properties, in principle, are known; see, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2 Aufl. Cold Spring Harbor Laboratory Press, Gold Spring Harbor, NY; or Winnacker "Gene und Klone", VCH Weinheim 2. Edition 1996 or Christou, "Trends in Plant Science" 1 (1996)423-431).

For such genetic manipulations you can enter the molecules of the nucleic acid in the plasmid, which allow mutagenesis or changing sequences due to recombination of DNA sequences. When 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 to slices mo the ut to 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 splits specific transcripts of the above 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 of sufficient length to cause antisense effect in the cells. Is also possible to use DNA sequences that have a high degree of gomologichnosti to coding sequences geneproduct, however, are not completely identical.

When the expression of nucleic acid molecules in plants are synthesized protein can be localized in a particular compartment. In order to achieve localization in a particular compartment, coding sequences can be linked, for example, DNA sequences that contribute to localization in the op is delannoy the compartment. Sequences of this kind are known to the person skilled in the art (e.g., 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. (1991), 95-106).

Transgenic plant cells can be regenerated known techniques to whole plants. And we are talking about any kind of transgenic plants, i.e. as monocots and dicots. Thus, the gain of transgenic plants which have modified properties due to irexpress, suppression or inhibition of homologous (natural) genes or genocidalists, or the expression of heterologous (foreign) genes or gene sequences.

Therefore, an object of the present invention is also a method of weed control plants, preferably in plant crops such as cereals (e.g. wheat, barley, rye, oats, rice, corn, millet), namely, that a synergistic combination of herbicides (a) and (B) is applied post-emergent to weeds or their parts.

We offer a synergistic combination of herbicides can be represented in the form of ready mixes the two components, if necessary, with other active substances, additives and/or auxiliary means used for preparation of preparative Faure is, then to use a normal manner diluted with water, and in the form of so-called tank mixes obtained by dilution with water separately compiled or partially separately compiled components.

The active substance (a) and (B) or their combinations can be obtained in different formulation, depending on the biological and/or chemico-physical parameters. We are talking about, for example, formulation, such as sprayable powders (WP), mulgirigala concentrates (EC), aqueous solutions (BP), emulsions such as emulsions of the type oil-in-water" and "water in oil"spray solutions or emulsions, dispersions on an oil or water based, suspoemulsions, pulverized products (PP), disinfectants, granules for injection into the soil or spreading, or dispergirujutsja in the water the granules (WG), ULV-preparative forms, microcapsules and waxes.

In principle, these certain types of medications forms are known and described, for example, in Winnacker-Kuchler, "Chemische Technologie", Band 7, C. Hauser Verlag Munchen, 4. Aufl. 1986, van Valkenburg, "Pesticide Formulations", Marcel Dekker, N.Y., 1973; K. Martens, "Spray Drying Handbook", 3rd Ed. 1979, G. Goodwin Ltd. London.

The tools needed for compiling preparative forms, such as inert materials, surfactants, solvents and other additives are also known and is ferocious, 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., Ridegewood N.J.; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N.Y. 1964; Schonfeldt, "Grenzflechenaktive Athylenoxidaddukte", Wiss. Verlagsgesellschaft., Stuttgart 1976, Winnacker-Kuchler, "Chemische Technologie", Band 7, S. HauserVerlag Munchen, 4. Aufl. 1986.

On the basis of these preparative forms also possible to obtain compositions with other substances pesticide action-for example, other herbicides, insecticides or fungicides, and also with protective agents, fertilizers or growth regulators, for example, in the form of ready preparative forms or through mixing in the tank.

Spray (wettable) powders are preparations evenly dispergiruyushchimi in the water, which, together with the active substance, with the exception of a diluent or inert substance, also include ionic and/or non-ionic surfactants (wetting agents, dispersing agents, for example polyoxyethylene ALKYLPHENOLS, polyethoxysiloxane fatty alcohols, polyethoxysiloxane fatty amines, alkanesulfonyl, alkylbenzenesulfonate, ligninsulfonate sodium 2,2’-dynafilter-6,6’-disulfonate sodium, debutylation-sulfonate sodium or sodium railneteurope acid.

The emulsion is arausiaca concentrates are obtained by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide,

xylene or high-boiling aromatic hydrocarbons or hydrocarbons, with the addition of one or more ionic and/or nonionic surfactants (emulsifiers). As emulsifiers can be used, for example, calcium salts alkylarylsulfonates acid, such as dodecylbenzenesulfonate calcium, or nonionic emulsifiers, such as polyglycolic ether fatty acids, alkylarylsulphonates ether, polyglycidyl ether of fatty alcohols, condensation products of propylene oxide and ethylene oxide, alkylhalides, sorbitane esters of fatty acids, for example, polyoxyethylenesorbitan ether fatty acids or polyoxyethylenesorbitan ether.

Spray powders are obtained by grinding the active substance with a powdered solid substances, for example talc, natural clays, such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.

The granules can be obtained by spraying the active substance capable of absorption, granulated inert material or by applying concentrates of active substances by using an adhesive agent, for example polyvinyl alcohol, sodium polyacrylate or mineral oils, to the surface of the base, such as sand, kaolinites or granulirovannye what about the inert material. Suitable active substances can also be granulated in the usual way, preferably in a mixture with fertilizer, to obtain granules of fertilizer.

Granular products, dispersible in water, are generally conventional manner, for example by spray drying, granulation in the vortex layer, graining on the plate, mixing with high-speed mixers and extrusion without the use of solid inert materials.

Agrochemical formulation contain as a rule 0.1 to 99 wt. -%, preferably 2-95% of the mass. the active substance a and/or B, and depending on the type of formulation used, the following concentrations:

in spray powders, the concentration of the active substance is, for example, about 10-95 wt. -%, the remainder to 100 wt%. consists of the usual components preparative forms;

in mulgirigala concentrates, the concentration of the active substance may be, for example, 5-80% of the mass;

powdered formulation containing at least 5-20% of the mass. the active substance;

spray solutions contain about 0.2-25% of the mass. the active substance;

in the pellets, for example dispergiruyushchie the granules, the active substance depends in part on, in solid or liquid state is active connection, and what use the form granulomas additives and fillers. Typically, the content in the granules, dispergiruyushchie in water, is 10-90% of the mass.

Along with this, these formulations of active substances, if necessary, contain a conventional adhesive agents, wetting agents, dispersing agents, emulsifying agents, penetrating agents, stabilizing agents, marathonissi agents and solvents, fillers, carriers and colorants, antispyware, evaporation inhibitors and agents which influence the pH or viscosity.

Is known, for example, that the action glufosinate-ammonium, as well as its L-enantiomers can be enhanced by the use of surfactants, preferably the wetting agent from a number of alkyl-polyglycolether, which contain, for example, 10-18 carbon atoms, and are applied in the form of their alkali or ammonium salts, and magnesium salts, for example With12-C14fatty alcohol-DigitalPersona-sodium (Genapol(r) LRO, Hoechst); see applications for European patents EP-A-0476555, EP-A-0048436, EP-A-0336151 or the U.S. patent And 4400196, as well as the OEWG. EWRS Symp. "Factors Affecting Herbicidal Activity and selectivity values", 227-232 (1988). It is also known that alkyl-polyglycolether as penetrating additives and amplifier efficiency are suitable for a number of other herbicides, such as herbicides from a number imidazolinones; see application in Europe is iski patent EP-A-0502014.

Preparative form, available in commercially available form, for example, spray powders, mulgirigala concentrates, dispersions and dispergirujutsja in water and pellets, for use, if necessary, diluted in the usual way with water. Powdered formulation, granules for injection into the soil or spreading, as well as the spray solution before use in the usual way a little diluted with other inert substances.

We offer a synergistic combination of herbicides preferably applied in the form of so-called tank mixes, and optimally prepared concentrated formulations of the individual active substances are mixed together with water in one tank and get a working solution is performed in post-harvest processing.

The advantage of the joint herbicide formulation proposed synergistic combinations of active substances (a) and (B) is the convenience in the application, because the number of components already adjusted to the desired value.

In addition, additives in preparative form optimally coordinated with each other, while mixing of different preparative forms in the tank can lead to undesirable combinations of additives.

Biological examples

Management of weeds before you shoot

Seeds or pieces of rhizomes monocotyledonous and dicotyledonous weeds are placed in pots filled with sandy loam soil and covered with earth. Means prepared in the form of concentrated aqueous solutions, wettable powders or emulsion concentrates, are then applied in the form of aqueous solutions, suspensions or emulsions is different doses adding a quantity of water corresponding to the rate of 600-800 l/ha on the surface of the planting area. After treatment, the pots are placed in a greenhouse and create conditions favorable for weed growth. 3-4 weeks after germination of the experimental plants perform visual analysis of the damage to the plants or seedlings compared to untreated control samples. As the results show, the proposed tools demonstrate good herbicide activity against a broad spectrum of weeds and weed grasses at pre-emergence treatment.

1. Evaluation and analysis of synergistic herbicide action

Herbicide activity of the active substances or mixtures of active substances visually assess the treated experimental plot in comparison with unhandled control plot. And assess the damage and development of all parts of the plant, located on the surface of the earth. Monitoring is carried out on a percentage scale (100% effect = the death of all plants; 50% effect = the death of 50% of the plants and the green parts of plants; 0% action = action no=control experimental plot).

The magnitude of the observations in the four experimental plots average. When the application is proposed in accordance with this invention compositions often see herbicide activity against species of weed RA the plants, which exceeds the sum of the effects of certain herbicides. An alternative in some cases, observe that using the composition of herbicides required minor rate to get the same effect against weeds compared with the individual drugs. This kind of improvement actions or the efficiency or economy of consumption rates due to significant manifestation of synergies. If the level is greater than the sum of the value of research with individual introductions and it exceeds the expected value according to Colby, which is calculated by the following formula, it is mistaken for a manifestation of synergies (see S.R.Colby; Weeds 15 (1967) p.20-22);

E=A+B-((A(B)/100),

where a, B = the inhibitory activity of the active substances a and B respectively, in %, a or B, g AC/ha;

E = the expected inhibitory effect in % with A + B g AB/ha (AB = active substance).

The obtained values of studies demonstrate the effect of the compositions at lower dosages, which correspond to the expected values according to Colby.

2. Management of weeds post-emergent

Seeds and pieces of rhizomes monocotyledonous and dicotyledonous weeds are placed in pots filled with sandy loam soil, covered with earth and placed in a greenhouse where they create conditions favorable for weed growth (temperature, humidity, Woden beanie). Three weeks after sowing, pilot plants, which are under 3 sheets, process proposed in accordance with this invention means. Proposed in accordance with this invention means is made in the form of powders or emulsion concentrates, in various dosages with the normal flow of water in the calculation of the rate of 600-800 l/ha sprayed onto the green parts of plants. About 3-4 weeks experienced plants kept in the greenhouse under optimum conditions for growth, and then conduct a visual analysis of the action of the drug compared with untreated control samples. Proposed in accordance with this invention means are demonstrating good herbicide activity against a broad spectrum of weeds and weed grasses in post-harvest processing.

Using this proposed compositions often see herbicide action that exceeds the sum of the effects of certain herbicides. The obtained results demonstrate the effect of the compositions at lower dosages, which is in excess of the expected values according to Colby (see observations in example 1).

3. Herbicide action and compatibility with cultivated plants (research field)

Cultivated plants grown in the open ground on the experimental plots in the natural is to promote the open ground, and the seeds or pieces of rhizomes typical weed plants were planted in advance or experimental plots naturally overgrown with weeds. The treatment proposed in accordance with this invention means is carried out after germination of weeds and cultivated plants, as a rule, at the stage of 2-4 leaves; partial (as indicated) conduct the processing of individual active substances or compositions of active substances before the shoot of plants (see example 1), or partially sequentially before the shoot and/or post-emergent. After 2, 4, 6 and 8 weeks after treatment perform visual analysis of the action of drugs in comparison with untreated control samples (see the analysis in example 1). Field proposed in accordance with this invention means also exhibit synergistic herbicide activity against a broad spectrum of weeds and weeds that have important economic value. The comparison showed that the proposed in accordance with this invention compositions show significantly stronger herbicide effect than the sum of the effects of certain herbicides, which is a manifestation of synergies. In addition, the action in the main time periods on the monitored space is above the expected values according to Colby (see the analysis in example 1), which also decrees the AET synergies. Cultivated plants, on the contrary, when the herbicide treatment means were not damaged or corrupted slightly.
