Description
Technical Field
The invention belongs to the field of pesticides; the present invention relates to a herbicidal composition; the invention also relates to a method for controlling undesired plant growth.
Background
The control of agricultural weeds has been the most concerned and important problem in agricultural production. Protection of crops from weeds and other vegetation that inhibit crop growth is a continuing problem in agriculture.
The use of chemical herbicides is one of the important hallmarks of modern agriculture. In recent years, the amount of herbicides sold has increased year by year, and the application area has also expanded year by year. However, with the continuous use of large areas of numerous herbicide species, numerous problems arise, such as the onset of emergence of weed resistance problems, particularly of resistance problems in older weeds; in addition, the problems of single action mode, short lasting period and the like of the single herbicide are also prominent. Therefore, it is an urgent need to provide a long-acting herbicide with a wide herbicidal range, strong selectivity and less resistance pressure to weeds.
It is known that the combined application of certain different herbicides with specific action may lead to an increase in the activity of the herbicide components compared to a simple additive action. This increase in activity is also referred to as a synergistic effect or synergistic activity. The application rates of the herbicidal active compounds required for controlling harmful plants can thus be reduced.
The most commonly used method of increasing herbicidal activity and broadening the herbicidal spectrum of existing herbicides is to mix two or more herbicidally active substances having different herbicidal activities. When the efficacy of a mixture of two or more ingredients is greater than the expected level of efficacy of each ingredient, we refer to as "synergy"; when the potency of a mixture of two or more ingredients is below the expected level of potency of the respective ingredient, we call "antagonism"; the efficacy of a mixture of two or more ingredients at the same level of intended efficacy of each ingredient is referred to as "additive". However, due to differences in herbicidal performance, absorption, transfer, metabolism, etc., most mixtures have less herbicidal activity than single applications of the ingredients. The synergistic effect present in herbicidal mixtures of two or more herbicidally active substances is only visible in some cases.
Disclosure of Invention
It is an object of the present invention to provide a herbicidal composition which shows a synergistic effect for the skilled worker in controlling a plurality of weeds or a weed species which is difficult to control after one or several applications of these herbicides on crops.

It has been found that, surprisingly, the combination of flufenacet, oxadiazon and pendimethalin exhibits a synergistic effect on weed control at or below the application rate compared to the application rate of the compounds alone, in particular at or below the application rate of alopecurospora, especially at or below alopecuroides Sobol, Poa annua L, chickweed (L.) Kumula, Versatium arvense L, Oxalium oxalicum L, Oxalicoriolus asiatica L, Symplocola indica (Becknianyzigachne (Steud.) Fernald, Symplocos japonica (Alopecurus japonicus), Symplocos canadensis L, Gynura japonica (Benth.) Kurill, Gynura japonica (Benula gracilium, Gynura procumbens, Gynura prochlora procumbens (Benia, Gynura prochlora procumbens, Gynura procumbens (Benia procumbens, Gynura procumbens, Verbenaria officinalis (Benzia procumbens, C. benaria) A benaria officinalis, Gynura procumbens, Gynura procumbe, Chenopodium album L, Xanthium sibiricum Patr, Acalypha australis L, Amaranthus retroflexus (Amaranthus retroflexus), trichosanthes japonica (convoluulus arvensis L), portulaca oleracea L, euphorbia lathyris ((Leptochloa beauve), Digitaria spp), Sagittaria sagittifolia (Sagittaria sagittifolia), polygonum Convolvulus (fallopia polygonum) convoluta, abutilon theoptera, alisma orientale (orientablata rhizum), monochorizonum vaginatum (duckspurk), monochamus vaginalis (fallopian), monochorium ramosum (leucotrichum sonchikurome), alisma japonica (orientin rhizum arvense), monochorium vaginatum (duckongrass), Monochoria florum ramosum (Monochoria), monochorina indica, monochamoides (Solanum indicum arvensis L), monochorina L, Monochoria L, and rosea indica (sorrow).
"synergistic" results in lower application rates for individual herbicides, greater efficacy at the same application rate, control of previously untreated varieties, control of varieties tolerant or resistant to a single herbicide or multiple herbicides, extended application periods, and/or reduced number of individual applications required; and for the user, a more economically and ecologically advantageous weed control system is obtained.
The oxadiazon application rate can vary within wide limits, for example between 10g and 1000g a.i./ha (hereinafter, a.i./ha means "active substance/hectare" based on 100% pure active compound). When applied at an application rate of 100g to 700g a.i./ha, oxadiazon has a relatively broad spectrum of harmful plants to be controlled when used before sowing, before planting or before and after emergence.
The application rate of flufenacet can vary within wide limits, for example between 10g and 1500 gA.I./ha. Flufenacet, when applied at an application rate of 100g to 1000gA.I./ha, has a relatively broad spectrum of harmful plants to be controlled when it is used before sowing, before planting or before and after emergence.
The application rate of pendimethalin can vary within wide limits, with a relatively broad spectrum of harmful plants to be controlled when pendimethalin is used before sowing, before planting or before and after germination, when applied at an application rate of 100g-2000g a.i./ha.
The herbicidal compositions of the present invention may also contain one or more other active compounds which are different from the flufenacet, oxadiazon, pendimethalin components and which also act as selective herbicides.
The herbicidal compositions of the present invention may also comprise other components of various active compounds, for example selected from safeners, fungicides, insecticides, acaricides, nematicides, bird repellents, soil conditioners, plant nutrients (fertilizers), and herbicides having a structure different from flufenacet, oxadiazon and pendimethalin, and plant growth regulators.

When the weeding composition is used together with glyphosate, glufosinate-ammonium, dicamba, imidazolinone, sulfonylurea, 2,4-D and the like, crops to be applied are glyphosate, glufosinate-ammonium, dicamba, imidazolinone, sulfonylurea or 2,4-D tolerant crops.
Although the flufenacet, oxadiazon and pendimethalin already show good or even sufficient selectivity in a large number of crops, in principle phytotoxicity to the crop plants may occur in some crops, in particular also when mixed with other less selective herbicides. Compositions comprising the herbicidal compositions according to the present invention together with one or more safeners are particularly advantageous. The safeners are used in antidotally effective amounts, for example to reduce the phytotoxic side effects of the herbicides used in economically important crops or in fruit plantations (plantation crops). Such as cereals (wheat, barley, rye, oats, corn, rice and millet), sugar beets, sugar cane, oilseed rape, peanuts, cotton, potatoes, soybeans.
The following are, for example, compounds suitable as safeners (including possible stereoisomers and agriculturally commonly used esters or salts): 1, 8-naphthalic anhydride (1, 8-naphthalene dicarboxycarbyl hydride), benoxacor (benoxacor), fenchlorazole (fenchlorazole-ethyl), Furilazole (Furilazole), jiecan (2-dichlomethyl-2-methyl-1, 3-dioxanone), chloranil (cyclometril), Oxabetrinil, fluxofenam (fluxofenam), Fenclorim (Fenclorim), fluzazole or oxaziridine (Acetamide), Isoxadifen (Isoxadifen), pyraclonil (Mefenpyr-diethyl).
Some safeners are known to act as herbicides and, accordingly, to act to protect crop plants in addition to having a herbicidal effect on harmful plants.
The weight ratio of herbicidal composition to safener generally depends on the application rate of the herbicide and on the effect of the safener and can vary within wide limits, for example within the range from 90000:1 to 1:5000, preferably within the range from 7000:1 to 1:1600, in particular within the range from 3000:1 to 1:500, in particular within the range from 1:100 to 20: 1. Safeners can be formulated with flufenacet, oxadiazon and pendimethalin in a finished formulation or supplied and used in tank mix with the herbicidal composition.
Safeners can be used for the preliminary treatment of the seed material of the cultivated plants (dressing) or can be penetrated into the soil before or after sowing. It can also be applied separately or together with the herbicidal composition of the present invention after the plants have germinated. The treatment of the plant or seed material with the safener is in principle not influenced by the time of application of the herbicide. The treatment of the plants can also be carried out by applying the herbicide and safener simultaneously, for example in the form of a tank mix.

TNV crops (TNV: trees, nuts and vines), including, for example, grapes, citrus, pome fruits, such as apples and pears, coffee, pistachios and oil palms, stone fruits, such as peaches, almonds, walnuts, olives, cherries, plums and apricots;
turf, pasture and pasture;
onion and garlic;
bulb ornamentals such as tulip and narcissus;
conifers and deciduous trees such as Pinus (Pinus), fir, oak, maple, dogwood, hawthorn, crabapple and Rhamnus (Rhamnus);
garden ornamentals such as petunia, marigold, roses and snapdragon.
The herbicidal compositions according to the invention are particularly suitable for controlling the growth of control/undesired vegetation in wheat, barley, rye, triticale, durum, rice, maize, sugarcane, sorghum, soybean, pulse crops such as pea, bean and lentils, peanut, sunflower, sugarbeet, potato, cotton, brassica crops such as oilseed rape, canola, mustard, cabbage and turnip, turf, grapes, pome fruit such as apple and pear, stone fruit such as peach, almond, walnut, olive, cherry, plum and apricot, citrus, coffee, pistachio, garden ornamentals such as rose, petunia, marigold, snapdragon, bulb ornamentals such as tulip and narcissus, conifers and deciduous trees such as pinus, fir, oak, maple, dogwood, hawthorn, crabapple.
The herbicidal compositions of the present invention are most suitable for use in, for example, oilseed rape, sugar beet, soybean, cotton, potato, peanut, rice, barley, wheat, corn and other cereal crops.
The herbicidal compositions of the present invention may also be used to control weeds in perennial crops. Such crops are, for example, forests, ornamental trees, fruits, vines, lemons, nuts, bananas, coffee, tea, rubber, oil palms, cocoa, berries and hop plantations.
The herbicidal composition of the present invention is effective against monocotyledonous and dicotyledonous weeds without substantially damaging the crop.
The herbicidal compositions of the present invention also provide excellent control of the growth of undesirable vegetation in non-crop areas. Non-crop areas such as roads, railways, lawns, utility lines, and particularly in areas where trees are present, undesirable vegetation.
The herbicidal compositions of the present invention may also be used for crop plants that are resistant to one or more herbicides due to genetic engineering or breeding, resistant to one or more pathogens, such as phytopathogenic fungi, due to genetic engineering or breeding or resistant to insect infestation due to genetic engineering or breeding. Suitable are, for example, crops which are resistant to synthetic auxins, preferably maize, wheat, sunflower, rice, canola, oilseed rape, soybean, cotton and sugar cane, or crops which are resistant to attack by certain insects as a result of introduction of genes for Bt toxins by genetic modification.
Use of a herbicidal composition for controlling undesired vegetation in crops of useful plants, which is tolerated by the crop of useful plants.
The herbicidal compositions of the present invention are highly suitable for selectively controlling the growth of undesirable vegetation in crops of useful plants. Particular preference is given to the growth of undesirable plants in wheat, peanut, corn, cotton, potato, rice crops.
The herbicidal compositions of the present invention may also be used as defoliants, desiccants and all-round herbicides.
The present invention provides a method for controlling undesired vegetation by applying flufenacet, oxadiazon and pendimethalin of the herbicidal composition of the present invention to undesired plants or their growing sites, collectively or individually.
A method for controlling undesired vegetation, comprising: (i) before the undesired plants germinate (pre-emergence); (ii) after undesired plant germination (post-emergence); or (iii) applying a herbicidally effective amount of the herbicidal composition of the present invention to the undesired plants or to the locus thereof at (i) and (ii). Preferably, the application of the germinated undesired vegetation (e.g. broadleaf weeds, grasses, cyperaceae or undesired crop plants) is also carried out before the undesired vegetation germinates, irrespective of the growth period of the sown/planted crop.
A method for controlling undesired vegetation, which comprises contacting the undesired plants or their habitat with a herbicidally effective amount of the herbicidal composition of the present invention.
A method for controlling undesired vegetation, which comprises applying a herbicidally effective amount of the herbicidal composition of the present invention to soil to prevent germination or growth of undesired plants.
The weeding composition comprises the flufenacet, the oxadiazon and the pendimethalin with effective amounts and has a synergistic effect. A synergistic effect is observed when flufenacet, oxadiazon, pendimethalin are applied together or almost simultaneously; synergy may also be observed when flufenacet, oxadiazon, pendimethalin are applied separately at different times; flufenacet, oxadiazon, pendimethalin may also be applied sequentially, for example, pre-emergent followed by post-emergent application, or early post-emergent followed by mid-or late post-emergent application. It is preferred here to apply flufenacet, oxadiazon, pendimethalin together or almost simultaneously, and co-application is particularly preferred.
If the herbicidal composition of the present invention is applied to the soil surface before germination, the weed seedlings are completely prevented from germinating, or the weeds grow to the cotyledon stage, but then they stop growing, and finally die completely after two to four weeks.
If the active compound is applied to the green parts of the plants after germination, the growth likewise stops sharply within a relatively short time after the treatment, and the weed plants remain in the growth phase at the point in time of application, or they die completely after a certain time, in such a way that the competition caused by the weeds which are harmful to the crop plants is eliminated earlier and continuously. For rice, the herbicidal composition may also be applied in water, which is then absorbed through the soil, shoots and roots.
When flufenacet, oxadiazon, pendimethalin are co-administered, there is a synergistic effect. Here, the activity of the composition is higher than the expected sum of the activities of the individual herbicides applied. The synergistic effect allows a reduction in the application rates, a broader spectrum of broadleaf weeds, grasses and cyperaceae to be controlled, a faster onset of action of the herbicidal action, a longer duration, a better control of harmful plants by only one or a few applications and a widening of the application period. The dosage used in the herbicidal composition, as well as the effective dosage of flufenacet, oxadiazon, pendimethalin, can be adjusted to lower levels to minimize their effect on the soil. This allows the herbicidal compositions of the present invention to be applied not only to sensitive crops but also almost avoid groundwater contamination. The herbicidal compositions of the present invention allow for a significant reduction in the required application rate of the active ingredient.
The above characteristics and advantages are for weed control to keep agricultural/forestry/horticultural crops or greens/grasslands free from undesired competing plants, thereby ensuring and/or increasing the yield levels of useful crops from a quality and quantity point of view. Such herbicidal compositions significantly exceed the state of the art in terms of said properties.
The present invention also provides a method of controlling undesired vegetation which comprises applying the herbicidal compositions of the present invention in the presence of the plants of the useful crop, the seeds of the useful crop or other reproductive parts of the useful crop. The herbicidal compositions according to the invention are preferably applied directly to the plants or to the locus of the plants before sowing or germination of the useful crop or after sowing before germination.
The present invention also provides a method for controlling undesired vegetation, preferably in crops of useful plants, in particular in crops of cereals, which comprises applying flufenacet, oxadiazon, pendimethalin as active ingredient of the herbicidal composition according to the invention, for example, jointly or separately to plants (for example undesired plants, such as monocotyledonous or dicotyledonous broadleaf weeds, grasses, cyperaceae or undesired crop plants), seeds (for example caryopsis, seeds or vegetative organs, for example tubers and sprouted branches), or to areas where plants grow (for example to areas of cultivation, which may also be covered with water). One herbicide may be applied to the plant, seed, or area where the plant is growing (e.g., the area of cultivation) before, after, or simultaneously with another herbicide.
The herbicidal compositions of the present invention may be applied in a conventional manner by using techniques well known to those skilled in the art. Suitable techniques include spraying, atomizing, dusting, broadcasting or pouring. The type of application depends in a well-known manner on the intended purpose; in any case, the technique should ensure the best possible distribution of the active ingredients according to the invention.
If the active ingredient is not well tolerated by certain crops, the herbicidal compositions can be directed to spray with the aid of a spray device so that they contact the sensitive crop as little as possible when they reach the foliage or bare soil of the undesirable plants growing below.
The method of the invention is most preferably used for controlling weeds in the area where the crop is growing or will be used for growing the crop, by unwanted plants or their locus. When applied to a crop growing area, the application rate should be sufficient to control weed growth without causing serious permanent damage to the crop.
"undesirable plants" are understood to mean all plants which grow in places where their growth is not desired. These may be, for example, harmful plants (for example monocotyledonous or dicotyledonous weeds, grasses, cyperaceae or unwanted crop plants), including, for example, those which are resistant to certain herbicidally active compounds (for example glyphosate, glufosinate, atrazine, imidazolinone herbicides and sulfonylureas).
The invention also provides a weeding composition which contains the active ingredients of flufenacet, oxadiazon and pendimethalin, and also comprises a filling agent and/or a surfactant. In the herbicidal composition, the total amount of flufenacet, oxadiazon and pendimethalin is from 1% to 90%, preferably from 5% to 80%, preferably from 10% to 80%, more preferably from 20% to 80%, more preferably from 30% to 80% by weight of the herbicidal composition.
The total amount of flufenacet, oxadiazon and pendimethalin may also comprise 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 52%, 54%, 56%, 58%, 60%, 62%, 64%, 66%, 68%, 70%, 72%, 74%, 76%, 78%, 80%, 82%, 84%, 86%, 88% or 90% by weight of the herbicidal composition.
The particular values between the above-mentioned values are not intended to be exhaustive or to limit the invention to the precise values encompassed within the stated ranges for brevity and conciseness.
The herbicidal composition of the present invention can be converted into conventional formulations such as wettable powders, emulsifiable concentrates, suspensions, microcapsules, microemulsions, aqueous emulsions, suspoemulsions, microcapsule suspension-suspensions, water dispersible granules, ultra-low volume liquids, tablets, low volume dispersible granules, pills or dry suspensions.
According to the present invention, the term "bulking agent" refers to natural or synthetic organic or inorganic compounds that can be combined or associated with an active ingredient to make it easier to apply to a subject (e.g., a plant, crop or grass). Thus, the filler is preferably inert, at least should be agriculturally acceptable. The filler may be solid or liquid.
Suitable solid carriers are: for example, vegetable powders (for example, particles of soybean powder, starch, cereal flour, wood flour, bark powder, saw dust, walnut shell powder, bran, cellulose powder, coconut shell, corn cob and tobacco stalk, residues after extraction of plant essences, etc.), clays (for example, kaolin, bentonite, acid china clay, etc.), talc powders, silicas (for example, diatomaceous earth, silica sand, mica, hydrous silicic acid, calcium silicate), activated carbon, natural minerals (for example, bentonite, silica gel, kaolin, pumice, attapulgite, zeolite, etc.), calcined diatomaceous earth, sand, plastic media (for example, polyethylene, polypropylene, polyvinylidene chloride, etc.), inorganic mineral powders such as potassium chloride, calcium carbonate and calcium phosphate, chemical fertilizers such as ammonium sulfate, ammonium phosphate, urea and ammonium chloride, and soil fertilizers, and these may be used alone or in combination of 2 or more.
Suitable liquid carriers may be selected from, for example, water, alcohols (e.g., methanol, ethanol, isopropanol, butanol, ethylene glycol, etc.), ketones (e.g., acetone, methyl ethyl ketone, diisobutyl ketone, cyclohexanone, etc.), ethers (e.g., diethyl ether, dioxane, methyl cellulose, tetrahydrofuran, etc.), aliphatic hydrocarbons (e.g., kerosene, mineral oil, etc.), aromatic hydrocarbons (e.g., benzene, toluene, xylene, mineral spirits, alkylnaphthalenes, chlorinated aromatic hydrocarbons, chlorinated aliphatic hydrocarbons, chlorobenzene, etc.), halogenated hydrocarbons, amides, sulfones, dimethyl sulfoxide, mineral and vegetable oils, animal oils, etc.
Suitable surfactants are emulsifiers, dispersants or wetting agents of an ionic or nonionic nature, or mixtures of these surfactants. Suitable examples of such surfactants include fatty alcohol-polyoxyethylene ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene higher fatty acid esters, phosphoric acid esters of polyoxyethylene alcohols or phenols, fatty acid esters of polyhydric alcohols, sodium alkylaryl sulfonates, naphthalenesulfonic acid polymers, lignosulfonates, high-molecular comb-shaped dendritic copolymers, butylnaphthalenesulfonates, alkylaryl sulfonates, sodium alkylsulfosuccinates, fats and oils, polyacrylates such as fatty alcohol-ethylene oxide condensates and alkylnaphthalenesulfonates, and protein hydrolysates. Suitable oligosaccharides or polymers are based, for example, on ethylene monomers, acrylic acid, polyoxyethylene or polyoxypropylene alone or in combination with, for example, (poly) alcohols or (poly) amines. When one of the active compounds and/or one of the inert carriers is insoluble in water and when applied in water, a surfactant must be present. The proportion of the surfactant is 5% -40% of the herbicidal composition of the present invention.
If appropriate, the herbicidal compositions according to the invention may also be provided with further additional components, for example protective colloids, adhesives, thickeners, thixotropic agents, penetrants, stabilizers, sequestering agents, complex-forming agents.

The herbicidal compositions according to the invention can be formulated, for example, by known methods as mixed preparations of the individual components, if appropriate with further active compounds, additives and/or customary formulation auxiliaries, and the compositions are then applied after dilution with water in a conventional manner; or can be formulated as a tank mix by diluting the separately formulated or partially separately formulated components together with water. It is also possible to apply the components separately or partly separately. The herbicide or herbicidal composition can also be used in multiple parts (sequential application), for example first pre-sowing/pre-planting or pre-emergence application followed by post-emergence application or early post-emergence application followed by mid-or late-emergence application. Preference is given here to using the active compounds of the composition together or almost simultaneously, particular preference being given to co-administration.
The method of application may be selected according to the intended subject and prevailing circumstances, such as foliar, drench, spray, dusting, scattering, according to the nature of the formulation.
Flufenacet, oxadiazon and pendimethalin can be applied as such, in their formulated form or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They can be applied in a conventional manner, for example by pouring, spraying, atomizing or broadcasting.
The herbicidal compositions of the present invention can be applied in a conventional manner, and can also be applied in the form of low-volume or ultra-low-volume technologies or as microgranules.
