Description

Bag fluorinated ketones contained sulphur grass amine and Fen Nuo kill the grand Herbicidal combination of sulphur

The invention belongs to the technical field of crop production compositions, described crop combination thing can be by the preceding method (incorporate into or do not incorporate into) of for example sowing; before the bud behind method or the bud method be used for the undesired plant of crop plants opposing following sowing and plantation: wheat (durum wheat and common wheat) for example; corn; soybean; sugar beet; sugarcane; cotton; rice (under dry land or paddy field condition with the rice plantation of indica type or round-grained rice type kind and crossbreed/mutant/GMO or sowing); beans (for example bush bean and broad bean); flax; barley; oat; rye; triticale; rape; potato; broomcorn millet (Chinese sorghum); herbage; greenery patches/lawn; fruit plantation (plantation crops) or the non-crop zone (square of residential area or industrial area for example; railroad track).Except single administration, also can carry out sequential application.

The purposes that the present invention relates to comprise the Herbicidal combination of at least two kinds of weed killer herbicides and be used for the undesired plant of control; particularly comprise and be selected from N-{2-[4; 6-dimethoxy-(1; 3,5) triazine-2-(carbonyl-or-methylol)]-the 6-halogenophenyl } compound of difluoro methylsulfonyl amine or its N-methyl-derivatives and/or its salt (hereinafter being also referred to as " the difluoro mesyl aniline that is replaced by the dimethoxy-triazine base ") and the Herbicidal combination of other weeding active compounds.

Substituted sulfonamide has weeding (for example WO93/09099A2, WO96/41799A1) on the known ring.It also comprises phenyl difluoro Methanesulfomide (it is also referred to as difluoro mesyl aniline).Described phenyl difluoro Methanesulfomide compound is, for example, especially by dimethoxypyridin base (for example WO00/006553A1, JP2000-6336, JP11-060562) or dimethoxy-triazine base and the single replacement of other halogenic substituents (for example WO2005/096818A1, WO2007/031208A2) or polysubstituted phenyl derivatives.

Yet, from N-{2-[4,6-dimethoxy-(1,3,5) triazine-2 (carbonyl-or-methylol)]-the 6-halogenophenyl } particular compound (as being described in WO2005/096818A1) of difluoro methylsulfonyl amine and N-methyl-derivatives thereof be (as being described in WO2006/008159A1 about bactericide first, and be described in WO2007/031208A2 and WO2009/024251A2 as weed killer herbicide) with regard to its weeding, be not entirely satisfactory in all respects.

The difluoro mesyl aniline that is replaced by the dimethoxy-triazine base is to noxious plant (broad leaved weed, grassy weed, sedge (Cyperaceae); Hereinafter also be referred to as " weeds ") activity of weeding be in higher level, but depend on rate of application, used preparation, noxious plant or noxious plant spectrum, weather and soil condition etc. to be prevented and treated in each case usually.Other standards herein are the acting duration of weed killer herbicide or resolution ratio, general crop plants compatibility and the speed of action (the more quick acting of effect), activity profile and to the performance (multiple cropping problem) of succeeding crop or the overall flexibility of using (preventing and treating the weeds under its each vegetative stage).If suitable, can also need consider the variation of noxious plant susceptibility, it is in the long-term use of weed killer herbicide or may have (control of tolerance or resistant weed kind) in limited geographic area.Compensate for the loss of the activity of single plant only feasiblely to a certain extent by the rate of application that improves weed killer herbicide, this is because for example this operation can reduce the selectivity of weed killer herbicide, even or because improvement is not seen in effect yet when rate of application is higher.

Therefore, often need the specific weeds kind of opposing the target synergistic activity, have the control of weeds of better global selectivity, still less the reactive compound of consumption reaches equal and good prevent and treat result and minimizing and enter reactive compound in the environment usually, to avoid for example leaching and residual effect.Also need to develop disposable employed with repeatedly the using of the intensive that shuns labor, wherein, except the initial control fast of weeds, also there is slower aftereffect control (residual control) in and the system of exploitation control action speed.

The possible solution of the problems referred to above be can be provides Herbicidal combination; be the mixture of multiple weed killer herbicide and/or other components, described other components are selected from dissimilar agrochemically active compounds and are usually used in crop protection and formulation auxiliary agents and the additive of required additional features are provided.Yet, in being used in combination of various active compound, chemistry, physics or the inconsistent phenomenon of biology, for example antagonism of the biologic activity of the decomposition of coupling preparation deficient in stability, reactive compound or reactive compound often appear.For those reasons, must select potential suitable bond in the mode of target, and with its adaptability of experimental test, can not ignore passive result or the positive result of priori safely.

The mixture of the non-N-methyl-derivatives of above-claimed cpd is known (for example WO2007/079965A2) in principle; Yet, its with the mixture of other weed killer herbicides in effect only from the individual cases of the phenyl derivatives that replaced by the dimethoxypyridin base, confirm.In addition, the N-methyl-derivatives and some mixture in conjunction with component (for example WO2008/101595A2, WO2010/017930A2, WO2010/017931A2, WO2010/017929A1, WO2010/017922A2, WO2010/017921A2, WO2010/017924A2, WO2010/017923A2, WO2010/017928A1, DE102008037630, WO2010/017927A2, WO2010/017926A2, WO2010/017925A2) that also have the above-claimed cpd through selecting.

An object of the present invention is to provide crop production compositions as the substitute of prior art or as its improvement product.

Unexpectedly, have now found that purpose of the present invention can be by fluorine ketone sulphur grass amine (triafamone; The ISO common name of proposing)---a kind of weed killer herbicide that is selected from the N-methyl-derivatives of the difluoro mesyl phenyl amines that is replaced by the dimethoxy-triazine base---kills the grand (fenoxasulfone of sulphur with the fragrant promise of compound; The ISO common name of proposing) combination realizes, they are with a kind of particularly advantageous mode acting in conjunction, for example be used at crop plants sowing and/or plantation when it---wheat (durum wheat and common wheat) for example, corn, soybean, sugar beet, sugarcane, cotton, rice (under dry land or paddy field condition with the rice plantation of indica type and/or round-grained rice type kind and crossbreed/mutant/GMO or sowing), beans (for example, bush bean and broad bean), flax, barley, oat, rye, triticale, rape, potato, broomcorn millet (Chinese sorghum), herbage, greenery patches/lawn---in, (the square of residential area or industrial area for example in the fruit plantation on (plantation crops) or the non-crop zone, railroad track), particularly when preventing and treating undesired plant in the rice crops (under the condition in dry land or paddy field with the rice plantation of indica type and/or round-grained rice type kind and crossbreed/mutant/GMO or sowing).

If the reactive compound with Herbicidal combination of the present invention before germinateing is applied to soil surface, prevent fully that then the weeds seedling from germinateing, perhaps weed growth is to cotyledon period, but it just stops growing then, and finally two thoughtful around after death fully.

If after germination, described reactive compound is applied to the green parts of plant, growth can just sharply stop in the suitable short time after processing equally, and the vegetative period when this ruderal plant remains on time of application point, perhaps it is fully dead after certain hour, thereby with the utmost point in this way early and eliminate the competition that is produced by the weeds that are harmful to crop plants constantly.For rice, also described reactive compound can be applied in the water, it is ingested by soil, bud and root then.

The characteristics of Herbicidal combinations of the present invention are rapid-action and long-acting herbicide effect.Usually, the resistance of rainwater washing against power of reactive compound is favourable in the bond of the present invention.A special advantage is that the dosage that uses in the described bond and compound (A) and effective dose (B) all are adjustable to lower level, so that its effect to soil is low to moderate optimum degree.This makes it at first not only can be applied to sensitive crop, has also almost avoided groundwater contamination.The bond of reactive compound of the present invention makes the required rate of application of reactive compound reduce significantly.

In a preferred embodiment, weed killer herbicide (A) and Herbicidal combination height of the present invention (B) are applicable to the noxious plant of optionally preventing and treating in the rice crops.Described rice crops is included in the institute of rice cultivation under the most diverse condition might form, and for example dry land is cultivated, cultivate in the nonirrigated farmland or cultivate in the paddy field, and wherein irrigating can be natural (rainfall) and/or artificial (pouring, flood irrigation).The seed (being obtained by sudden change or transgenosis) that the rice that is used for this purpose can be conventional seed, the hybrid seed of cultivating or has resistance---tolerance---at least, it can be derived by indica type or round-grained rice type kind or its crossbreed.

Can use Herbicidal combination of the present invention by the various application processes that are usually used in rice herbicides.Particularly preferably, it is used by spray application and/or by dipping.In dipping was used, when using, the water in paddy field had covered ground and had been up to 3-20cm.Then Herbicidal combination of the present invention is for example directly placed the water in paddy field with the form of granule.Worldwide, spray application is mainly used in the directly rice of sowing, and dipping is used the rice that is mainly used in transplanting.

Herbicidal combination of the present invention has covered wideer weeds spectrum, and described weeds spectrum especially has specificity to rice crops.For example following weeds are all had good control: in the monocotyledon weed with the subordinate, Echinochloa for example, Panicum, annual bluegrass belongs to, Sprangletop, Brachiaria, knotgrass, setaria, Cyperus, Monochoria (Monochoria spp.), genus fimbristylis, arrowhead belongs to (Sagittaria spp.), Eleocharis (Eleocharis spp.), Scirpus (Scirpus spp.), Waterplantain (Alisma spp.), leaf of bamboo Lepidium (Aneilema spp.), water screening spp (Blyxa spp.), eriocaulon buergerianum (Eriocaulon spp.), Potamogeton (Potamogeton spp.) etc. all prevents and treats finely, particularly following kind: water barnyard grass (Echinochloa oryzicola), Monochoria vaginalis (Monochoria vaginalis), yak grass (Eleocharis acicularis), scouring rush's shape water chestnut (Eleocharis kuroguwai), difformed galingale herb (Cyperus difformis), Herba Cyperi Glomerati (Cyperus serotinus), short arrowhead (Sagittaria pygmaea), alisma canaliculatum (Alisma canaliculatum), firefly Lin (Scirpus juncoides).Under the situation of broadleaf weed, activity profile extends to the subordinate, for example Polygonum; Han Lepidium (Rorippa spp.), joint joint Lepidium (Rotala spp.), Vandellia (Lindernia spp.), Bidens (Bidens spp.), cusp Pittosporum (Sphenoclea spp.), the horsefly eye belongs to (Dopatrium spp.), Eclipta prostrata belongs to (Eclipta spp.), Elatine ambigua (Elatine spp.), Gratiola (Gratiola spp.), Vandellia (Lindernia spp.), ludwigia (Ludwigia spp.), Oenanthe (Oenanthe spp.), Ranunculus (Ranunculus spp.), pool chilly genus (Deinostema spp.) etc.Particularly such as following kind: mexicana (Rotala indica), cusp flower (Sphenoclea zeylanica), Procumbent Falsepimpernel (Lindernia procumbens), false loosestrife (Ludwigia prostrate), pondweed (Potamogeton distinctus), waterwort (Elatine triandra), Chinese celery (Oenanthe javanica).

When weed killer herbicide (A) and weed killer herbicide (B) when using jointly, there be preferred super adding and (=collaborative) effect.At this, the activity of described bond is higher than the expection summation of each herbicidal activity of using.Synergy can reduce rate of application, prevent and treat more broad leaved weed, grassy weed and the sedge of wide range, the herbicide effect onset is faster, the duration is longer, just noxious plant is had better control and can widen the phase of using by only once or several times using.To a certain extent, by using said composition, also reduced harmful constituent for example nitrogen or oleic acid amount and be incorporated into amount in the soil.

Above-mentioned characteristic and advantage are avoided undesired competitive plant for putting into practice control of weeds to keep agricultural/forestry/horticultural crop or greenery patches/meadow, thereby guarantee and/or increase yield level to be necessary from the angle of quality and quantity.With regard to described characteristic, this new Herbicidal combination has surmounted the state of the art of this area significantly.

Because weeding characteristic and the plant growth regulating characteristic of Herbicidal combination of the present invention, Herbicidal combination of the present invention are used in the known plant crop or still tolerance leaved for development or genetic modification crop and contain and can prevent and treat noxious plant in the plant.Generally speaking, genetically modified plants (GMO) are characterised in that to have particularly advantageous character, except the resistance to Herbicidal combination of the present invention, for example also to plant disease or the pathogenic biology of plant disease, for example some insect or microorganism such as fungi, bacterium or virus have resistance.Other concrete feature relates to for example quantity, quality, the storage characteristics of harvested material, and the composition of specific components.Therefore, genetically modified plants known content of starch raising or that starch quality changes, or wherein harvested material has different fatty acid composition or the vitamin content that increases or the genetically modified plants of energy properties.In the same way, because its weeding and plant growth regulating character, described reactive compound also can be used for preventing and treating the crop of known plants or treats selecting noxious plant in the plant of developing and sudden change and crossbreed genetically modified plants by sudden change.

Generation is compared the conventional method with the new plant that improves characteristic and is comprised for example traditional breeding method and generation mutant with existing plant.Perhaps, have the new plant that improves character can produce by means of recombination method (referring to, for example EP-A-0221044, EP-A-0131624).Following method has for example been described in some versions:

● for starch synthetic in the plant is carried out modification, modify crop plants (for example WO92/11376, WO92/14827, WO91/19806) by means of recombinant technique

● the genetically modified crops plant, its to weed killer herbicide for example sulfonylureas present resistance (EP-A-0257993, US-A-5013659)

● have the genetically modified crops plant of the ability of generation bacillus thuringiensis (Bacillus thuringiensis) toxin (Bt. toxin), it makes plant have resistance (EP-A-0142924, EP-A-0193259) to some insect

● have the genetically modified crops plant (WO91/13972) of the fatty acid composition of change

A large amount of molecular biotechnologies is known in principle, can produce by means of these methods to have the new genetically modified plants of improving characteristic; Referring to, Sambrook et al. for example, 1989, Molecular Cloning, A Laboratory Manual, 2 ^NdEdition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY; Or Winnacker " Gene und Klone ", VCH Weinheim2 ^NdEdition1996 or Christou, " Trends in PlantScience " 1 (1996) 423-431).In order to implement this reorganization operation, can will allow the nucleic acid molecules of sudden change or sequence variation to introduce plasmid by the dna sequence dna reorganization.For example, above-mentioned standard method allows to take place the base exchange, sequence removes, and perhaps adds natural or synthetic sequence.For dna fragmentation is interconnected, joint or conjugant can be added to these fragments.

For example, generation with the plant cell that reduces active gene prod can perhaps realize by expressing at least a ribozyme that cuts off the appropriate structuring of transcribing of said gene product specifically by expressing at least a corresponding antisense RNA, a kind of realization inhibiting just RNA altogether.

For this reason, can use the whole coded sequences that comprise gene prod, the dna molecular that comprises any side group sequence that may exist, and the dna molecular that only comprises the part coded sequence, these parts must long enough in cell, to have the antisense effect.Also can use with the coded sequence height homology of gene prod but and the DNA that not exclusively is equal to it.

When at the plant interior expression nucleic acid molecules, synthetic protein can be arranged in any required chamber of plant cell.Yet, in order to be implemented in the location in the particular chamber, coding region is connected with the dna sequence dna of guaranteeing to locate in particular chamber.This sequence is that well known by persons skilled in the art (referring to, Braun et al. for example, EMBO is (1992) J.11,3219-3227; Wolter et al., Proc.Natl.Acad.Sci.USA85 (1988), 846-850; Sonnewald et al., Plant is (1991) J.1,95-106).

Put in order the strain plant by the renewable transgenic plant cells of known technology to grow up to.In principle, genetically modified plants can be the plants of arbitrarily required plant variety,, monocotyledon are arranged not only that is, also have dicotyledon.Therefore, can express, check or the expression of inhibition or allos (=external) gene or gene order obtains the genetically modified plants that character changes by the mistake of homology (=natural) gene or gene order.

The present invention also provides selectivity to prevent and treat the method for undesired plant, preferably in crop plants, the undesired plant of control in the rice crops (under dry land or paddy field condition with indica type or round-grained rice type kind and/or rice that crossbreed/mutant/the GMO kind is planted or sowed) particularly, this method comprises component (A) and weed killer herbicide (B) as Herbicidal combination of the present invention, for example be applied to plant (noxious plant for example together or respectively, as unifacial leaf or dicotyledonous broad leaved weed, grassy weed, sedge or undesired crop plants), seed (caryopsis for example, seed or vegetative propagation organ, for example stem tuber and the band bud branch portion), perhaps be applied to the zone (for example Zai Pei zone, its also available water covering) of plant growth.A kind of weed killer herbicide can be before another kind of weed killer herbicide, be applied to plant afterwards or with it simultaneously, the zone (for example Zai Pei zone) of seed or plant growth.
