    [001] [001] The present invention relates to the herbicidal mixture comprising L-glufosinate or its salt and at least one protoporphyrinogen-IX oxidase inhibitor. The invention also relates to a method to control desirable vegetation in cutting programs (burndown), in the management of industrial vegetation and forestry, in plant and perennial crops and in peat and grass. BACKGROUND OF THE INVENTION
    [002] [002] Mowing, that is, the complete removal of weeds from the soil by applying herbicides, before planting or emergence of a crop, is an important tool in modern weed management.
    [003] [003] In industrial weed management and forestry, it is desirable to control a wide variety of weeds for a long period of time. Control of large weeds or taller species, such as shrubs or trees, may also be desirable. Industrial weed management includes, for example, rail and walkway management, fence lines and non-arable land, such as industrial and construction sites, gravel areas, roads or sidewalks. Forestry includes, for example, clearing existing forests or woodland, removing regrowth after mechanically cutting the forest, or managing weeds in forest plantations. In the latter case, it may be desirable to protect desirable trees from contact with the spray solution containing the herbicidal mixture according to the present invention.
    [004] [004] Vegetable crops include, for example, eggplant (aubergine), beans, peppers, cabbage, pepper, cucumber, eggplant, lettuce, melon, onion, potato, sweet potato, spinach and tomato. For the control of weeds in plant cultures, it may be desirable to protect the crops from contact with the spray solution containing the herbicidal mixture according to the present invention.
    [005] [005] Perennial crops include trees, nuts and vines, such as almond, apple, apricot, avocado, cashew, cherry, Christmas trees, durian, orange, dragon fruit, grapes, guava, longan, mango, olive, papaya, peach, pears and other pomoid fruits, pistachio, plum, pomegranate, pomelo and quince and citrus crops, including, for example, tangerine, grapefruit, lemon, lime, tangerine and nectarine, as well as nut crops , including, for example, hazelnut, macadamia and walnut; and plantations such as banana, cocoa, coconut, coffee, palm oil, pepper and other spices, maple, rubber, sugar cane and tea.
    [006] [006] The compositions according to the invention can also be used for the control of weeds in peat and grass, as long as the desirable grass species are tolerant to the herbicidal mixture. In particular, these mixtures can be used in desirable grass that has become tolerant to glufosinate by mutagenesis or genetic engineering.
    [007] [007] Glufosinate and its salts are non-selective systemic herbicides, with good post-emergence activity against numerous weeds and, therefore, can be used in cutting programs, in the industrial management of vegetation and forestry, in vegetable and perennial crops and in peat and grass. However, application to the soil of glufosinate often produces unsatisfactory weed control, and multiple applications and / or high dosage rates are often necessary. In addition, the effectiveness of glufosinate against some weeds is not entirely sufficient.
    [008] [008] Therefore, it is often recommended to apply glufosinate in combination with at least one additional herbicide. However, the effectiveness of such combinations is often unsatisfactory and high application rates are still necessary to achieve acceptable weed control. In addition, the reliability and persistence of such combinations depends heavily on climatic conditions and some difficulty in controlling weed species can escape. In addition, the herbicidal activity of these mixtures persists only for a short period of time, which allows effective cutting only within a short period of time before planting a crop.
    [009] [009] Thus, it is an objective of the present invention to provide a herbicidal mixture, which allows an efficient and reliable control of grass and broadleaf weeds in a cutting program, in the management of industrial vegetation and forestry, in vegetable crops and perennials and in peat and grass. In addition, the persistence of the herbicidal activity of the mixture must be sufficiently long in order to achieve weed control over a sufficiently long period thus allowing a more flexible application. The mixture must also have a low toxicity to humans or other mammals. The mixtures must also demonstrate accelerated action on harmful plants, that is, they must cause damage to harmful weeds more quickly compared to the application of individual herbicides.
    [010] [010] Glufosinate is a racemate of two enantiomers, of which only one shows sufficient herbicidal activity (see, for example, US 4265654 and JP 92448/83). Although various methods are known for preparing L-glufosinate (and their salts), mixtures known in the art do not point to stereochemistry, which means that the racemate is present (for example, WO 2003024221, WO 2011104213, WO 2016113334, WO 2009141367 ).
    [011] [011] Surprisingly, it was found that mixtures of L-glufosinate or its salt and at least one protoporphyrinogen-IX oxidase inhibitor show a higher activity in cutting programs, in industrial management of vegetation and forestry, in vegetable crops and perennials and in peat and grass, compared to L-glufosinate alone.
    [012] [012] Surprisingly, it was found that mixtures of L-glufosinate or its salt and at least one protoporphyrinogen-IX oxidase inhibitor show a better activity in cutting programs, in industrial management of vegetation and forestry, in plant and perennial crops and in peat and grass, compared to mixtures of racemic glufosinate and at least one protoporphyrinogen-IX oxidase inhibitor. DESCRIPTION OF THE INVENTION

    [054] [054] The invention also relates to a herbicidal formulation, which comprises an active herbicidal mixture as defined herein and at least one carrier material, including liquid and / or solid carrier materials.
    [055] [055] Various types of oils, humectants, adjuvants, fertilizers,
    [056] [056] The user applies the mixture according to the invention normally from a pre-dosing device, a back sprayer, a spray tank, a spray plane or an irrigation system. Usually, the agrochemical mixture is prepared with water, buffer and / or other auxiliaries to the desired application concentration and the ready-to-use spray liquor or the agrochemical mixture according to the invention is thus obtained. Usually, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to-use spray liquid are applied per hectare of useful agricultural area.
    [057] [057] As mentioned above, the invention also relates to the use of a mixture as defined here for the control of undesirable vegetation in cutting programs, in the management of industrial vegetation and forestry, in plant and perennial crops and in peat and gram, in which the inventive mixtures can be applied pre- or post-emergence, that is, before, during and / or after the emergence of undesirable plants. Application as a post-emergence treatment, that is, during and / or after the emergence of undesirable plants is preferred. Here, the inventive mixtures are applied to a location where crops will be planted before planting or emergence of crop plants.
    [058] [058] Therefore, the present invention also relates to a method for the treatment of cutting undesirable vegetation in crops, which comprises applying an inventive mixture to a place where the crops will be planted before planting (or sowing) or the emergence of culture plant. Here, the inventive mixture is applied to undesirable vegetation or in its location.
    [059] [059] Thus, the present invention therefore relates to a method for controlling undesirable vegetation, which method comprises applying an inventive mixture to a location where undesirable vegetation is present or expected to be present, where the application can be done before, during and / or after, preferably during and / or after the emergence of undesirable vegetation.
    [060] [060] As used herein, the terms "control" and "combat" are synonymous.
    [061] [061] As used herein, the terms "undesirable vegetation", "undesirable species", "undesirable plants", "harmful plants", "undesirable weeds" or "harmful weeds" are synonymous.
    [062] [062] The term “local”, as used here, means the area in which vegetation or plants are growing or will grow, typically a field.
    [063] [063] In such cutting programs, the inventive mixtures can be applied before sowing (planting) or after sowing (or planting) the crop plants, but before the emergence of the crop plants, in particular, before sowing . The mixtures of the invention are preferably applied before sowing the crop plants. For cutting, the inventive mixtures will generally be applied on a date up to 9 months, often up to 6 months, preferably up to 4 months before planting the crop. The cut application can be done on a date up to 1 day before the emergence of the crop plant and is preferably done on a date prior to sowing / planting the crop plant, preferably on a date of at least one day, preferably at least 2 days, and in particular at least 4 days before planting or from 6 months and 1 day before emergence, in particular from 4 months to 2 days before emergence and more preferably from 4 months to 4 days before the emergency. It is, of course, possible to repeat the cutting application once or more, for example, once, twice, three times, four times or five times within that period.
    [064] [064] It is a particular benefit of the mixtures of the invention that they have very good post-emergence herbicidal activity, that is, they show good herbicidal activity against emergent undesirable plants.
    [065] [065] In the case of post-emergence treatment of plants, the mixtures of the invention are preferably applied by foliar application.
    [066] [066] If the active compounds I and II are less well tolerated by certain plants, application techniques can be used in which the herbicidal compositions are sprayed, with the help of the spray equipment, so that, as far as possible, they do not come into contact with the leaves of sensitive crop plants, while the active substances reach the leaves of the undesirable plants that grow beneath them, or the surface of the bare soil (post-directed, lay-by).
    [067] [067] The application can be carried out, for example, by usual spraying techniques with water as a carrier, using amounts of spray mixture generally between 10 and 2,000 l / ha, in particular 50 to 1000 l / ha.
    [068] [068] The required application rate of the mixture of the pure active compounds depends on the density of the unwanted vegetation, the stage of development of the plants, the climatic conditions of the place where the mixture is used and the method of application. In general, the application rate of the mixture is 55 to 6000 g / ha, preferably 100 to 5000 g / ha, 200 to 4000 g / ha, and more preferably 300 to 3000 g / ha of active ingredient (ai )
    [069] [069] When using the mixtures of the invention in the methods of the present invention, the active compounds present in the mixtures of the invention can be applied simultaneously or in succession, where undesirable vegetation can occur. Here, it is irrelevant whether the individual compounds present in the mixtures of the invention are formulated together or separately and applied together or separately, and, in the case of a separate application, in which order the application should occur. It is only necessary, that the individual compounds present in the mixtures of the invention be applied in a period of time, which allows a simultaneous action of the active ingredients on the unwanted plants.
    [070] [070] As mentioned above, the mixtures of the invention have several advantages, i.e., improved herbicidal action in comparison, if compared with mixtures of racemic glufosinate with a protoporphyrinogen-IX oxidase inhibitor.
    [071] [071] Furthermore, the inventive mixtures show persistent herbicidal activity, even under difficult climatic conditions, which allows for a more flexible application in cutting in cutting applications and minimizes the risk of weeds escaping. In addition, the inventive mixtures show superior compatibility with crop plants with certain conventional crop plants and herbicide-tolerant crop plants, that is, their use in these crops leads to a reduction in damage to crop plants and / or does not result in increased damage to crop plants. In this way, the mixtures of the invention can also be applied after the emergence of the crop plants. The inventive mixtures can also have an accelerated action on harmful plants, that is, they can cause weed damage more quickly, compared to mixtures of racemic glufosinate with at least one protoporphyrinogen-IX oxidase inhibitor.

    [076] [076] The mixtures of the invention are suitable for combating / controlling harmful plants common in fields, where useful plants must be planted (ie in crops). The mixtures of the invention are generally suitable for cutting unwanted vegetation in fields of the following crops:
    [077] [077] The mixtures of the invention are particularly suitable for cutting unwanted vegetation in the fields of the following plants: small grain crops such as wheat, barley, rye, triticale and durum, rice, maize, sugar cane, sorghum , soybeans, legume crops such as peas, beans and lentils, peanuts, sunflowers, beets, potatoes, cotton, Brassica crops, such as rapeseed, canola, mustard, cabbage and turnip, peat, pastures, pastures, grapes, pormoid fruits such as apple and pear, stone fruits such as peach, almond, walnut, pecans, olive oil, cherry, plum and apricot, citrus fruits, coffee, pistachios, ornamental garden plants such as roses, petunia, marigold, snapdragon, ornamental plants with bulbs such as tulips and daffodils, conifers and deciduous trees such as pine, fir, oak, maple, dogwood, hawthorn, sour apple, and alder.
    [078] [078] The inventive mixtures are best suited for cutting unwanted vegetation in areas of the following crop plants: small grain crops such as wheat, barley, rye, triticale and durum, rice, corn, sugar cane, soy, crops legumes such as peas, beans and lentils, peanuts, sunflowers, cotton, Brassica cultivation plants, such as rapeseed, canola, peat, pastures, pastures, grapes, stone fruits such as peach, almond, walnut, pecans, olive, cherry, plum and apricot, citrus and pistachio.
    [079] [079] The invention also relates to the use of a mixture as defined here for the control of undesirable vegetation in crops in a cutting program, in which the culture is produced by genetic engineering or by crossing, are resistant to one or more herbicides and / or pathogens such as plant pathogenic fungi and / or insect attack; preferably resistant to glufosinate.
    [080] [080] Thus, as used in the present invention, the term "crops", as used in this document, also includes (cultivated) plants that have been modified by mutagenesis or genetic engineering, in order to provide a new feature to a plant or modify a feature already present.
    [081] [081] Mutagenesis includes techniques of random mutagenesis using X-rays or mutagenic chemicals, but also techniques of targeted mutagenesis in order to create mutations in a specific locus of a plant genome. Targeted mutagenesis techniques often use oligonucleotides or proteins like CRISPR / Cas, zinc finger nucleases, TALENs or meganucleases to achieve the target effect.
    [082] [082] Genetic engineering generally uses recombinant DNA techniques to create changes in the genome of a plant that under natural circumstances cannot be easily achieved by crossing, mutagenesis or natural recombination. Typically, one or more genes are integrated into a plant's genome to add a trait or improve a trait. These integrated genes are also referred to as transgenes in the art, while plants that comprise these transgenes are called transgenic plants. The transformation process of the plant generally produces several transformation events, which differ in the genomic locus into which a transgene has been integrated. Plants that comprise a specific transgene at a specific genomic locus are generally described as comprising a specific "event", which is referred to by a specific event name. Characteristics that have been introduced into plants or have been modified include, in particular, herbicide tolerance, insect resistance, increased yield and tolerance to abiotic conditions, such as drought.
    [083] [083] Herbicide tolerance was created using mutagenesis and genetic engineering. Plants that have been made tolerant to acetolactate synthase (ALS) inhibiting herbicides by conventional mutagenesis and crossbreeding methods comprise varieties of plants available commercially under the name Clearfield®. However, most herbicide tolerance characteristics were created through the use of transgenes.
    [084] [084] Herbicide tolerance for glyphosate, glufosinate, 2,4-D, dicamba, oxynyl herbicides, such as bromoxynil and ioxinil, sulphonylurea herbicides, ALS-inhibiting herbicides and inhibitors of 4-hydroxyphenylpyruvate dioxigenase (HPPD), as created isoxaflutol and mesoxafil.
    [085] [085] Transgenes that have been used to provide herbicide tolerance characteristics include: for glyphosate tolerance: epsps cp4, epsps grg23ace5, mepsps, 2mepsps, gat4601, gat4621 and goxv247, for tolerance to glufosinate: pat and bar, for tolerance to 2,4-D: aad-1 and aad-12, to tolerance to dicamba: dmo, to tolerance to oxynil herbicides: bxn, to tolerance to sulfonylurea herbicides: zm-hra, csr1-2, gm-hra , S4-HrA, for tolerance to ALS-inhibiting herbicides: csr1-2, for tolerance to HPPD-inhibiting herbicides: hppdPF, W336 and avhppd-03.

    [090] [090] Insect resistance was created primarily by transferring bacterial genes from insecticidal proteins to plants. The most frequently used transgenes are Bacillus spec toxin genes. and synthetic variants thereof, such as cry1A, cry1Ab, cry1Ab-Ac, cry1Ac, cry1A.105, cry1F, cry1Fa2, cry2Ab2, cry2Ae, mcry3A, ecry3.1Ab, cry3Bb1, cry34Ab1, cry35Ab1, cry9C, vip3A (a), vipA However, also, genes of plant origin were transferred to other plants. In particular, genes encoding protease inhibitors, such as CpTI and pinII. Another approach uses transgenes to produce double-stranded RNA in plants to target and downregulate insect genes. An example for this transgene is dvsnf7.
    [091] [091] Transgenic maize events comprising genes for insecticidal proteins or double-stranded RNA are, for example, but not excluding others, Bt10, Bt11, Bt176, MON801, MON802, MON809, MON810, MON863, MON87411, MON88017, MON89034, 33121 , 4114, 5307, 59122,

    [094] [094] An increase in yield was created by increasing the ear biomass using the athb17 transgene, being present in the MON87403 corn event or improving photosynthesis using the bbx32 transgene, being present in the MON87712 soy event.
    [095] [095] Cultures comprising a modified oil content were created using the transgenes: gm-fad2-1, Pj.D6D, Nc.Fad3, fad2-1A and fatb1-A.
    [096] [096] Tolerance to abiotic conditions, in particular drought tolerance, was created using the cspB transgene, composed of the MON87460 corn event and using the Hahb-4 transgene, comprised of the IND-ØØ41Ø-5 soy event.
    [097] [097] The traits are often combined by combining genes in one transformation event or by combining different events during the creation process. Combinations of preferred characteristics are herbicide tolerance for different groups of herbicides, insect tolerance to different types of insects, in particular tolerance to lepidopteran and coleopteran insects, tolerance to herbicides with one or more types of insect resistance, tolerance to herbicides with greater yield and combination of herbicide tolerance and tolerance to abiotic conditions.
    [098] [098] Plants comprising unique or stacked characteristics, as well as the genes and events that provide these characteristics are well known in the art. For example, detailed information about the mutagenized or integrated genes and the respective events are available on the websites of the organizations “International Service for the Acquisition of Agro-biotechnological Applications (ISAAA)” (http://www.isaaa.org/gmapprovaldatabase) and the “ Environmental Risk Assessment Center (CERA) ”(http://cera-gmc.org/GMCropDatabase), as well as in patent applications, such as EP 3 028 573 and WO 2017/011288.
    [099] [099] The use of mixtures of the invention in cultures can result in effects that are specific to a culture that comprises a particular gene or event. These effects may involve changes in growth behavior or altered resistance to biotic or abiotic stressors. Such effects may, in particular, include improved yield, improved resistance or tolerance to insects, nematodes, fungal, bacterial, mycoplasma, viral or viroid pathogens, as well as early vigor, early or delayed ripening, tolerance to cold or heat, as well as alteration of amino acids or spectrum or content of fatty acids.

    [0107] [0107] The mixtures of the invention can be applied in a conventional manner, using techniques known to those skilled in the art. Suitable techniques include spraying, atomizing, dusting, spreading or watering. The type of application depends on the intended purpose in a well-known manner; in any case, they must guarantee the best possible distribution of the active substances according to the invention.
    [0108] [0108] In one embodiment, the mixtures of the invention are applied to the site mainly by spraying, in particular the foliar spraying of an aqueous dilution of the active ingredients of the mixture. The application can be carried out by usual spraying techniques using, for example, water rates as a carrier and spray liquor of about 10 to 2000 l / ha or 50 to 1000 l / ha (for example, from 100 to 500 l / ha) there is). The application of the inventive mixtures by the low-volume and ultra-low-volume method is possible, as well as their application in the form of microgranules.
    [0109] [0109] The required application rate of the mixture of the pure active compounds depends on the density of the unwanted vegetation, the stage of development of the plants, the climatic conditions of the place where the mixture is used and the application method.
    [0110] [0110] In general, the application rate of L-glufosinate is generally 50 g / ha to 3000 g / ha and preferably in the range of 100 g / ha to 2000 g / ha or 200 g / ha at 1500 g / ha of active substance (ai), and the application rate of the protoporphyrinogen-IX oxidase inhibitor is from 1 g / ha to 2000 g / ha and preferably in the range of 5 g / ha to 1500 g / ha, more preferably from 25 g / ha to 900 g / ha of active substance (ai).
    [0111] [0111] The following examples illustrate the invention without imposing any limitations.
    [0112] [0112] Synergism can be described as an interaction in which the combined effect of two or more compounds is greater than the sum of the individual effects of each of the compounds. The presence of a synergistic effect in terms of percentage control between two mixing partners (X and Y) can be calculated using Colby's equation (Colby, SR, 1967, Calculating Synergistic and Antagonistic Responses in Herbicide Combinations, Weed, 15, 21 - 22):
    [0113] [0113] When the observed combined control effect is greater than the expected (calculated) combined control effect (E), the combined effect is synergistic.
    [0114] [0114] The following tests demonstrate the effectiveness of controlling compounds, mixtures or compositions of this invention in specific weeds. However, the weed control provided by compounds, mixtures or compositions is not limited to these species. The analysis of synergism or antagonism between mixtures or compositions was determined using the Colby equation.
    [0115] [0115] The culture vessels used were plastic pots containing clay sand with approximately 3.0% humus as a substrate. The seeds of the test plants were sown separately for each species and / or resistant biotype. For pre-emergence treatment, the active ingredients, suspended or emulsified in water, were applied directly after sowing by means of fine distribution nozzles. The containers were gently irrigated to promote germination and growth and later covered with transparent plastic layers until the plants took root. This coverage caused uniform germination of the test plants, unless this had been hampered by the active ingredients. For post-emergence treatment, the test plants were first grown at a height of 3 to 15 cm, depending on the plant's habit, and only then treated with the active ingredients that had been suspended or emulsified in water. To that end, the test plants were either sown directly and grown in the same containers, or were first grown separately as seedlings and transplanted to the test containers a few days before treatment. Depending on the species, the plants were kept at 10 - 25 ° C or 20 - 35 ° C, respectively. The test period was extended to 20 days after treatment. During this period, the plants were treated and their response to individual treatments was evaluated. The evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants or complete destruction of at least the parts above the ground, and 0 means no damage or normal course of growth. The data shown is the average of two replicates.
