Description

 Herbicide combination with a dimethoxytriazinyl-substituted difluoromethanesulfonylanilide

description

The present invention is in the technical field of

Pesticides which are active against undesired plant growth, for example (eg) in the pre-sowing process (with or without incorporation), preemergence or postemergence in sown and / or planted crops such as in wheat (hard and soft wheat), corn, soybean, sugar beet, Sugar cane, cotton, rice (planted or sown under 'upland' or 'paddy' conditions with Indica and / or Japonica species and hybrids / mutants / GMOs), beans (such as

For example, bush bean and horse bean), flax, barley, oats, rye, triticale, rapeseed, potato, millet (sorghum), pasture grass, green / lawns, in orchards (plantation crops) or on non-cultivated areas (eg squares of residential and industrial plants , Track systems) can be used. In addition to the single application, sequence applications are also possible.

It relates to a herbicide combination containing at least two herbicides and their use for controlling undesired plant growth, in particular a herbicide combination containing a compound from the group of N- {2- [4,6-dimethoxy- (1, 3,5) triazine-2 (-carbonyl or -hydroxy-methyl)] - 6-halo-phenyl} - difluoromethanesulfonamides or their / V-methyl derivatives and / or their salts, hereinafter also referred to as "dimethoxytriazinyl-substituted Difluormethansulfonylanilide", and a another herbicidal active ingredient. It is known that cyclic-substituted sulfonamides have herbicidal properties (for example WO 93/09099 A2, WO 96/41799 A1). These include the phenyldifluoromethanesulfonamides, which are also referred to as Difluormethansulfonylanilide. The latter are e.g. around

Phenyl derivatives which are monosubstituted or polysubstituted, inter alia with Dimethoxypyimidinyl (eg WO 00/006553 A1, JP2000-63360, JP1 1-060562) or dimethoxytriazinyl and a further halogen substitution (eg WO 2005/096818 A1, WO 2007/031208 A2). Specific compounds selected from the group consisting of A / - {2- [4,6-dimethoxy- (1, 3,5) triazine-2 (- carbonyl or -hydroxy-methyl)] - 6-halo-phenyl} -difluoromethanesulfonamides, as described in U.S. Pat WO 2005/096818 A1, and their / V-methyl derivatives, as described in

WO 2006/008159 A1 in connection with fungicides for the first time and in

However, WO 2007/031208 A2 and WO2009 / 024251 A2 are described as herbicides, but their herbicidal properties are not completely exhaustive

satisfactory.

The herbicidal activity of dimethoxytriazinyl-substituted

Difluoromethanesulfonylanilides against harmful plants (weeds, weed grasses,

Cyperaceae; hereafter referred to collectively as "weeds") is already at a high level, but generally depends on the

Application rate, the particular form of preparation, each to be controlled harmful plants or the Schadpflanzenspectrum, the climate and

Soil conditions, etc. from. Other criteria in this context are the duration of the action or the degradation rate of the herbicide, the general crop tolerance and rate of action (faster effectiveness), the spectrum of activity and behavior towards secondary crops (replication problems) or the general application flexibility (control of weeds in their various stages of growth). If necessary, changes in the susceptibility of harmful plants to be taken into account, if longer

Application of herbicides or geographically limited may occur

(Control of tolerant or resistant weed species). Losses of activity in individual plants can only be compensated to a limited extent by higher application rates of the herbicides, e.g. because it reduces the selectivity of the herbicides or does not improve the efficacy even at higher application rates.

Thus, there is often a need for specifically synergistic activity over specific ones Weed species, a weed control with overall better selectivity, a generally lower drug use for equally good control success and for a lower input of active ingredient into the environment, for example, to avoid "leaching" and "carry-over" effects. There is also a need for the

Development of "one-shof applications to labor-intensive

 To avoid multiple applications, as well as in the development of systems for controlling the rate of action, in addition to a first, rapid weed control and a slow, residual-acting control is set.

A possible solution to the above-mentioned problems may be the provision of herbicide combinations, that is, the mixture of several herbicides and / or other components from the group of agrochemical active ingredients of other types as well as in crop protection conventional additives and formulation auxiliaries, which contribute the desired additional properties. However, the combined use of several drugs often causes phenomena of chemical, physical or biological incompatibility, e.g. lack of stability in a common formulation, decomposition of an active substance or antagonism in the biological activity of the active ingredients. Therefore, potentially suitable combinations have to be selected and tested experimentally for their suitability, whereby negative as well as positive results can not be ruled out in advance.

Mixtures of non-W-methyl derivatives of the abovementioned compounds are known in principle (for example WO 2007/079965 A2), but their activity in mixtures with other herbicides is proven in individual cases only with dimethoxypyimidinyl-substituted phenyl derivatives. In addition, there are also mixtures of selected / V-methyl derivatives of the abovementioned compounds with some combination partners (for example WO 2008/101595 A2, WO 2010/017930 A2, WO

2010/017931 A2, WO 2010/017929 A1, WO 2010/017922 A2, WO 2010/017921 A2, WO 2010/017924 A2, WO 2010/017923 A2, WO 2010/017928 A1, DE

102008037630, WO 2010/017927 A2, WO 2010/017926 A2, WO 2010/017925 A2). The object of the present invention was to provide the prior art with alternative or improved pesticides.

Surprisingly, it has now been found that this task by the

Combination of Triafamone ("proposed ISO common name"), a herbicide from the group of / V-methyl derivatives of dimethoxytriazinyl-substituted

Difluoromethanesulfonylanilides, with the compound Fenoxasulfone ("proposed ISO common name") can be solved, in a particularly favorable manner

cooperate; e.g. when it comes to fighting unwanted

Plant growth in sown and / or planted crops such as wheat (hard and soft wheat), corn, soybean, sugarbeet, sugarcane, cotton, rice (planted or sown under 'upland' or 'paddy' conditions with indica and / or japonica - Species as well as hybrids / mutants / GMOs), beans (such as bush bean and horse bean), flax, barley, oats, rye, triticale, rapeseed, potato, millet (sorghum), pasture, green / lawns, in orchards

(Plantation crops) or on non-cultivated areas (eg squares of residential and industrial plants, railway tracks), especially in rice crops (planted or sown under 'Upland' or 'Paddy' conditions with Indica and / or Japonica species and hybrids / Mutants / GMOs) can be used.

The present invention thus relates to a herbicide combination containing components (A) and (B), wherein

(A) means the compound described by the formula (A):

 and

 (B) means the compound described by the formula (B):

Component (A) is a herbicidally active compound from the group of N-methyl derivatives of dimethoxytriazinyl-substituted difluoromethanesulfonylanilides and is described in the literature cited above to this group as active ingredient alone and in combinations with other herbicides. In addition to the labeling by formula (A), the compound is characterized by the "proposed ISO common name" triafamone and the systematic chemical names: 2 '- [(4,6-dimethoxy-1,3,5-triazin-2-yl ) carbonyl] -1, 1, 6'-thfluoro-A / -methylmethanesulfonanilides (IUPAC) or A / - [2 - [(4,6-dimethoxy-1,3,5-triazin-2-yl) carbonyl] 6-fluorophenyl] -1, 1-difluoro- / V-methylmethanesulfonamide (CA Index Name) and the CAS Registry Number (CAS Regno.): 874195-61-6.

Component (B) is a compound known as an active ingredient for controlling undesirable plant growth; see for example JP 2004-002324 A and the literature cited therein. In addition to the labeling by formula (B), the compound is characterized by the "proposed ISO common name" fenoxasulfone and the systematic chemical name: 2,5-dichloro-4-ethoxybenzyl 4,5-dihydro-5,5-dimethyl-1 , 2-oxazol-3-yl suifone (IUPAC) or 3 - [(2,5-dichloro-4-ethoxybenzyl) sulfonyi] -4,5-dihydro-5,5-dimethyl-1,2-oxazole (IUPAC) or 3 - [[(2,5-dichloro-4-ethoxyphenyl) methyl] sulfonyl] -4,5-dihydro-5,5-dimethylisoxazole (CA Index Name) and by the CAS Reg no .: 639826-16 -7 and through the

Short Names ("Code Names") KUH-071 and KIH-1419. Under the

Designation KUH-071, this compound has already been associated with herbicide combination of dimethoxytriazinyl-substituted

 Difluoromethanesulfonylaniiiden mentioned (WO 2010/017930 A2, WO 2010/017931 A2, WO 2010/017929 A1, WO 2010/017922 A2, WO 2010/017921 A2, WO 2010/017924 A2, WO 2010/017923 A2, WO 2010/017928 A1 DE 102008037630, WO

2010/017927 A2, WO 2010/017926 A2, WO 2010/017925 A2), but only generically within the scope of a list of other agrochemical active substances which can potentially be additionally mixed with the respective herbicidal combinations according to the invention. Examples with KUH-071 are not included in the above-mentioned literature and there is no evidence whatsoever of using KUH-071 directly in combination with compounds from the dimethoxytriazinyl-substituted difluoromethanesulfonylanilide group.

The formulas (A) and (B) mentioned include all possible forms of use, such as acids, salts, esters and isomers, such as stereoisomers and optical isomers. In detail, all stereoisomers and mixtures thereof, in particular also racemic mixtures, are included, and - as far as enantiomers are possible - the respective biologically active enantiomers. This also applies to possible rotamers. Possible salt formation can be effected by the action of a base on those compounds which carry an acidic hydrogen atom.

Suitable bases are, for example, organic amines, such as trialkylamines,

Morpholine, piperidine or pyridine and ammonium, alkali or

Alkaline earth metal hydroxides, carbonates and bicarbonates, in particular sodium and potassium hydroxide, sodium and potassium carbonate and sodium and Potassium hydrogen carbonate, alkali metal or alkaline earth metal, especially sodium or potassium, ethyl, n-propyl, i-propylate, n-butoxide or t-butylate. These salts are compounds in which the acidic hydrogen is replaced by a cation suitable for agriculture, for example metal salts, in particular

Alkali metal salts or alkaline earth metal salts, especially sodium and potassium salts, or ammonium salts, salts with organic amines or quaternary

(Quaternary) ammonium salts, for example with cations of the formula [NRR ^' R ^" R ^'" ] ⁺ , wherein R to R ^'" each independently represent an organic radical, in particular alkyl, aryl, arylalkyl or alkylaryl and alkylsulfoxonium salts, such as (CrC ₄ ) -trialkylsulfonium and (CC ₄ ) -trialkylsulfoxonium salts The compounds of the formula (I) can also be prepared by addition of a suitable inorganic or organic acid, such as

For example, mineral acids such as HCl, HBr, H ₂ S0 ₄ , H ₃ P0 ₄ or HNO ₃ , or organic acids, such as carboxylic acids such as formic acid, acetic acid, propionic acid, oxalic acid, lactic acid or salicylic acid or sulfonic acids, such as p- Toluene sulfonic acid, to form a basic group, such as amino, alkylamino, dialkylamino, piperidino, morpholino or pyridino, salts. These salts then contain the conjugate base of the acid as an anion. In the following, for the term "component (s)", the terms "herbicide (s)", "single herbicide (s)", "compound (s)" or "active ingredient (s)" are used interchangeably in context.

The herbicidal combination of components (A) and (B) according to the invention may contain additional additional components: e.g. agrochemical active substances of another type and / or additives customary in plant protection and / or

Formulation aids, or used together with these. in the

In the following, the use of the term "herbicidal combination (s)" or "combination (s)" also includes the "herbicidal agents" thus produced.

In a preferred embodiment, the herbicidal combination according to the invention contains the herbicides (A) and (B) in an effective content and / or synergistic effects. The synergistic effects can be observed, for example, when the herbicides (A) and (B) are applied together, for example as a co-formulation or as a tank mixture, but they can also be detected in the case of staggered application (split application, splitting). It is also possible to use the herbicides or the herbicide combination in several portions (sequence application), eg after pre-emergence applications, followed by post-emergence applications or early post-emergence applications, followed by mid-late post-emergence applications. Preference is given to the joint or the timely application of the herbicides (A) and (B) of the respective combination, particularly preferably the joint application.

The synergistic effects allow a reduction in the application rates of the individual herbicides, a higher and / or longer potency at the same

Application rate, the control of previously unrecognized species (gaps), the control of species that have tolerances or resistances to single or multiple herbicides, an extension of the period of application and / or a reduction in the number of necessary individual applications and - as a result for the user - economically and ecologically more beneficial weed control systems. For example, the combination of herbicides (A) and (B) according to the invention makes possible synergistic increases in activity which go far and unexpectedly beyond the effects achieved with the individual herbicides (A) and (B). The herbicide (A) mainly inhibits the enzyme acetolactate synthase (ALS) and thus protein biosynthesis in plants. The application rate of the herbicide (A) can vary within a wide range, for example between 0.1 g and 1000 g AS / ha (AS / ha in the following refers to "active substance per hectare" = based on 100% active ingredient) with application rates of 0.1 g to 1000 g AS / ha of the herbicide (A) is in Vorsaat-, Vorpflanz- or pre and

Postemergence method combats a relatively broad spectrum of harmful plants, for example on annual and perennial, monocotyledonous or dicotyledonous weeds, weeds, Cyperaceans and undesirable crops. In the combination according to the invention, the application rates are generally lower, for example in the range of 0.1 g to 500 g AS / ha, preferably 0.5 g to 200 g AS / ha, more preferably 1 g to 150 g AS / ha.

The application rate of the herbicide (B) can vary within a wide range, for example between 1 g and 1500 g AS / ha (AS / ha in the following means "active substance per hectare" = based on 100% active ingredient), wherein a relatively broad In the combination according to the invention, the application rates are generally lower, for example in the range from 1 g to 1500 g AS / ha, preferably from 2 g to 1000 g AS / ha, more preferably from 3 g to 800 g AS /Ha.

Areas for suitable proportions of the compounds (A) and (B) are given by e.g. from the stated application rates for the individual substances. In the

combination of the invention, the application rates can be reduced as a rule. Preferred mixing ratios of the combined herbicides (A): (B) in the combination according to the invention are characterized by the following weight ratios:

The weight ratio (A) :( B) of components (A) and (B) is generally in the range of 1: 1500 to 500: 1, preferably 1: 1000 to 100: 1, more preferably 1: 200 to 20: 1.

Preference is given to herbicide combinations, in addition to the inventive

Combination, also one or more further, of the herbicides (A) and (B) different agrochemical active compounds, which also have the function of a selective herbicide contain.

Furthermore, the herbicide combination according to the invention can be used as additional further components various agrochemical active ingredients, for example from the group of safeners, fungicides, insecticides, acaricides, nematicides, bird repellants, soil conditioners, plant nutrients (Fertilizers), and structurally from the herbicides (A) and (B) different herbicides and plant growth regulators or from the group of customary in crop protection additives and formulation auxiliaries.

Thus, as further herbicides, for example, the herbicides which differ structurally from the herbicides (A) and (B) are suitable, preferably herbicidal active compounds which are based on an inhibition of, for example, acetolactate synthase, acetyl-CoA carboxylase, cellulose synthase, enolpyruvylshikimate- 3-phosphate synthase, glutamine synthetase, p-hydroxyphenylpyruvate dioxygenase, phytoene desaturase, photosystem I, photosystem II, protoporphyrinogen oxidase are based, can be used, for example from Weed Research 26 (1986) 441-445 or "The Pesticide Manual", 15th edition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2006 and cited therein. As known herbicides or plant growth regulators which can be combined with the compounds according to the invention are e.g. to name the following active ingredients (the

Compounds are denoted either by the common name according to the International Organization for Standardization (ISO) or by the chemical name or by the code number) and always include all forms of use such as acids, salts, esters and isomers such as stereoisomers and optical isomers.

Of particular interest is the selective control of harmful plants in crops of commercial and ornamental plants. Although the herbicides (A) and (B), already in many cultures have good to sufficient selectivity, in principle, in some cultures and especially in the case of mixtures with others

Herbicides that are less selective, phytotoxicities on crops occur. In this regard, the combination of herbicides (A) and (B) of particular interest containing the herbicidally combined active ingredients and one or more safeners according to the invention is of particular interest. The safeners, which are used in an antidote effective content, reduce the phytotoxic side effects of the herbicides / pesticides used, e.g. in economically important crops such as cereals (wheat, barley, rye, oats, corn, rice, millet), sugar beet, sugar cane, oilseed rape, cotton, soybean or in fruit growing plants (plantation crops), preferably cereals, especially rice.

Some of the safeners are already known as herbicides and thus develop in addition to the herbicidal effect in harmful plants at the same time also protective effect in the

Crops.

The weight ratio of herbicide combination to safener depends on

Generally from the application rate of herbicide and the effectiveness of the particular safener and may vary within wide limits, for example in the range of 90000: 1 to 1: 5000, preferably 7000: 1 to 1: 1600, especially 3000: 1 to 1: 500. The safeners can analogously to the herbicides (A) and (B) or their

Mixtures with other herbicides / pesticides are formulated and as

Ready-to-use formulation or tank mix with the herbicides and applied or used separately as a seed, soil or foliar application.

The herbicide combination according to the invention (= herbicidal agent) has a excellent herbicidal activity against a broad spectrum of economically important monocotyledonous and dicotyledonous weeds, such as weeds, grass weeds or

Cyperaceans, including species which are resistant to herbicidal active substances such as glyphosate, glufosinate, atrazine, imidazolinone herbicides, sulfonylureas, (hetero) aryloxy-aryloxyalkyl carboxylic acids or phenoxyalkyl carboxylic acids (so-called 'fops'), cyclohexanedionoximes (so-called' Dims') or auxin inhibitors. Even difficult to control perennial harmful plants, which expel from rhizomes, rhizomes or other permanent organs are well detected by the active ingredients. The substances may be e.g. be applied in pre-sowing, pre-emergence or post-emergence, e.g. together or separately. Preferred is e.g. the

Post-emergence application, in particular on the accumulated

Harmful plants.

Specifically, by way of example, some representatives of the monocotyledonous and dicotyledonous weed flora can be mentioned, which can be controlled by the compounds according to the invention, without the intention of limiting them to certain species.

On the side of the monocotyledonous weeds, e.g. Ave na spp., Alopecurus spp., Apera spp., Brachiaria spp., Bromus spp., Digitaria spp., Lolium spp.,

 Echinochloa spp., Leptochloa spp., Fimbristylis spp., Panicum spp., Phalaris spp., Poa spp., Setaria spp. and Cyperus species from the annuelle group and on the part of the perennial species Agropyron, Cynodon, Imperata and Sorghum and also perennial Cyperusarten well.

For dicotyledonous weed species, the spectrum of activity extends to species such as Abutilon spp., Amaranthus spp., Chenopodium spp., Chrysanthemum spp., Galium spp., Ipomoea spp., Kochia spp., Lamium spp., Matricaria spp., Pharitis spp. , Polygonum spp., Sida spp., Sinapis spp., Solanum spp., Stellaria spp., Veronica spp. Eclipta spp., Sesbania spp., Aeschynomene spp. and Viola spp., Xanthium spp., on the annual side, as well as Convolvulus, Cirsium, Rumex, and Artemisia in perennial weeds. If the active compounds of the herbicidal combination according to the invention are applied to the surface of the earth before germination, then either the emergence of the weed seedlings is completely prevented or the weeds grow up to

Cotyledon stage, but then stop their growth and eventually die after two to four weeks.

Upon application of the active ingredients to the green parts of the plants postemergence also occurs very quickly after treatment, a drastic halt in growth and the weed plants remain in the existing at the time of application Wach stu m sstad ium stand or die after a certain time completely off, so that in this way a weed competition harmful to crops is eliminated very early and sustainably. The active ingredients can also be applied in rice in the water and are then absorbed by soil, shoot and root.

The herbicide combination according to the invention is characterized by a rapidly onset and long-lasting herbicidal action. The rainfastness of the active ingredients in the combination according to the invention is generally favorable. A particular advantage is the fact that the effective and used in the combination doses of compounds (A) and (B) can be set so low that their soil effect is optimally low. Thus, their use is not only possible in sensitive cultures, but groundwater contamination is virtually avoided. By the inventive combination of

Active ingredients, a significant reduction in the required application rate of the active ingredients is possible.

In a preferred embodiment, the herbicidal combination of the herbicides (A) and (B) according to the invention is outstandingly suitable for the selective control of harmful plants in rice crops. This includes all possible forms of the

Rice cultivation with a variety of conditions, such as dry ("upland", "dry") or water cultivation ("paddy"), whereby the irrigation can of course be done ("rainfall") and / or artificially ("irrigated", "flooded") , For the rice used here it may be conventionally bred seed, hybrid seed, but also resistant, at least tolerant seed (mutagenic or transgenic), which can be derived from the indica or Japonica and from crosses of the two.

The herbicide combination according to the invention can be used in all types of administration which are customary for rice herbicides. It is used particularly advantageously in the spray application and / or in the "submerged application". In the so-called "submerged application", the accumulation water already covers the soil by up to 3 -20 cm at the time of application. The inventive

Herbicide combination is then directly, e.g. in the form of a granulate in the water of the accumulated fields. Worldwide, the spray application is mainly used for seeded rice and the so-called submerged application, mainly for transplanted rice.

The herbicide combination according to the invention comprises a broad spectrum of weeds which is specific for rice crops in particular. On the side of the monocots

Weeds are e.g. Genera, such as Echinochloa spp., Panicum spp., Poa spp., Leptochloa spp., Brachiaria spp., Digitaria spp., Setaria spp. Cyperus spp.,

Monocho a spp., Fimbristylis spp., Sagittaria spp., Eleocharis spp., Scirpus spp., Alisma spp., Aneilema spp., Blyxa spp., Eriocaulon spp., Potamogeton spp. and the like, in particular the species Echinochloa oryzicola, Monochoha vaginalis, Eleocharis acicularis, Eleocharis kuroguwai, Cyperus difformis, Cyperus serotinus, Sagittaria pygmaea, Alisma canaliculatum, Scirpus juncoides. In the dicotyledonous weeds, the spectrum of action extends to genera, e.g. Polygonum spp., Rorippa spp., Rotala spp., Lindernia spp., Bidens spp., Sphenoclea spp., Dopatrium spp., Eclipta spp., Elatine spp., Gratiola spp., Lindernia spp., Ludwigia spp., Oenanthe spp , Ranunculus spp., Deinostema spp. and similar. Species such as Rotala indica, Sphenoclea zeylanica, Lindernia

procumbens, Ludwigia pro st rate, Potamogeton distinctus, Elatine triandra, Oenanthe javanica are well recorded. When the herbicide (A) and the herbicide (B) are used together, superadditive (= synergistic) effects preferably occur. Here is the effect

(Effectiveness) in the combination stronger than the expected sum of the

Effects of the individual herbicides used. The synergistic effects allow a reduction of the application rate, the control of a broader spectrum of weeds, grass weeds and Cyperaceae, a faster use of the herbicidal action, a longer lasting effect, a better control of the

Harmful plants with only one or a few applications and an extension of the possible period of application. In part, the use of the combination also reduces the amount of harmful ingredients, such as nitrogen or oleic acid, and their entry into the soil.

The mentioned properties and advantages are in the practical

Weed control required to agricultural / forestry / horticultural crops or grassland / pastures of unwanted

 To keep competitive plants free and thus to secure and / or increase yields qualitatively and quantitatively. The technical standard is significantly exceeded by this new herbicide combination in terms of the properties described.

On account of their herbicidal and plant growth regulator properties, the herbicide combination according to the invention can be used to combat

Harmful plants are used in known crops or to be developed tolerant or genetically modified crop and energy crops. The transgenic plants (GMOs) are usually distinguished by particular advantageous properties, in addition to the resistance to the herbicidal combination according to the invention, for example, by resistance to plant diseases or pathogens of plant diseases such as certain insects or microorganisms such as fungi, bacteria or viruses.

Other special properties concern, for example, the crop in terms of quantity, quality, shelf life, and the composition of special ingredients. Thus, transgenic plants with increased starch content or altered quality of Starch or those with other fatty acid composition of the crop or increased vitamin content or energy properties known. Similarly, the active ingredients may be due to their herbicidal and

plant growth regulatory properties also for controlling harmful plants in crops of known or yet to be developed by

 Mutant selection of plants obtained, and from crosses of mutagenic and transgenic plants.

Well-known routes for the production of new plants which have modified properties compared to previously occurring plants consist, for example, in classical breeding methods and the production of mutants. Alternatively, new plants with altered properties can help

genetic engineering methods (see for example EP-A-0221044, EP-A-0131624). For example, several cases have been described

genetically engineered modifications of crops to modify the starch synthesized in the plants (e.g., WO 92/1 1376, WO 92/14827, WO 91/19806),

 transgenic crops which have resistance to herbicides, for example to sulfonylureas (EP-A-0257993, US-A-5013659), - transgenic crops having the ability

 Bacillus thuringiensis toxins (Bt toxins) to produce, which the

 Make plants resistant to certain pests (EP-A-0142924, EP-A-0193259).

 Transgenic crop plants with modified fatty acid composition (WO 91/13972).

Numerous molecular biology techniques that can be used to produce novel transgenic plants with altered properties are known in principle; See, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2nd Edition Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY; or Winnacker "Genes and Clones", VCH Weinheim 2nd edition 1996 or Christou, "Trends in Plant Science" 1 (1996) 423-431) .These gene engineering manipulations can Nucleic acid molecules are introduced into plasmids that allow mutagenesis or a sequence change by recombination of DNA sequences. For example, base substitutions can be made, partial sequences removed, or natural or synthetic sequences added using the standard procedures outlined above. For the connection of the DNA fragments with one another adapters or linkers can be attached to the fragments.

The production of plant cells with a reduced activity of a

Gene product can be obtained, for example, by the expression of at least one corresponding antisense RNA, a sense RNA to obtain a

Cosuppressionseffektes or the expression of at least one appropriately engineered ribozyme, specifically transcripts of the above

Gene product splits. For this purpose, DNA molecules may be used which comprise the entire coding sequence of a gene product, including any flanking sequences that may be present, as well as DNA molecules which comprise only parts of the coding sequence, which parts must be long enough to be present in the cells to cause an antisense effect. Also possible is the use of DNA sequences that have a high degree of homology to the coding

 Have sequences of a gene product but are not completely identical.

In the expression of nucleic acid molecules in plants, the synthesized protein may be located in any compartment of the plant cell. However, to achieve localization in a particular compartment, e.g. the coding region is linked to DNA sequences which ensure localization in a particular compartment. Such sequences are known to those of skill in the art (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al., Proc. Natl. Acad., U.S.A. 85 (1988), 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106).

The transgenic plant cells can be whole by known techniques Plants are regenerated. The transgenic plants may in principle be plants of any plant species, ie both monocotyledonous and dicotyledonous plants. Thus, transgenic plants are available which have altered properties by overexpression, suppression or inhibition of homologous (= natural) genes or gene sequences or expression of heterologous (= foreign) genes or gene sequences.

The present invention furthermore relates to a process for the selective control of undesirable plants, preferably in plant crops, in particular in rice crops (planted or sown under 'upland' or 'paddy').

Conditions with Indica and / or Japonica species and hybrids / mutants / GMOs), which is characterized in that the herbicides as components (A) and (B) of the herbicidal combination according to the invention on the plants (eg harmful plants such as mono- or dicotyledonous weeds, grass weeds, cyperaceans or undesirable crops), the seed (eg grains, seeds or vegetative

 Propagating organs such as tubers or sprouts with buds) or the area on which the plants grow (e.g., the acreage which may also be covered by water), e.g. together or separately. One of the herbicides may be applied to the plants, seed or area on which the plants grow (e.g.

Undesirable plants are understood to mean all plants that grow in places where they are undesirable. This can e.g. Harmful plants (e.g., monocotyledonous or dicotyledonous weeds, weed grasses, cyperaceans or undesirable crops), e.g. also those which are active against certain herbicidal active substances such as glyphosate, glufosinate, atrazine, imidazolinone herbicides, sulfonylureas, (hetero) aryloxyaryloxyalkylcarboxylic acids or phenoxyalkylcarboxylic acids (so-called 'fops'),

Cyclohexanedionoxime (so-called 'dims') or auxininhibitors are resistant.

The herbicide combination according to the invention will be used selectively for controlling undesired plant growth, for example in crops such as Arable farming eg monocotyledonous crops such as cereals (eg wheat, barley, rye, oats, rice, corn, millet) or dicotyledonous crops such as sugarbeet, sugarcane, oilseed rape, cotton, sunflowers and legumes eg of the genera Glycine (eg Glycine max non-transgenic glycines max (eg conventional varieties such as STS varieties) or transgenic glycines max (eg RR soy or LL soy) and their crosses), Phaseolus, Pisum, Vicia and Arachis, or vegetable crops from various botanical groups such as Potato, leek, cabbage, carrot, tomato, onion, in orchards (plantation crops), green, lawn and pasture areas or on non-cultivated areas (eg squares of residential and industrial plants, railway tracks), in particular in rice crops (planted or sown under Upland or paddy conditions with Indica and / or Japonica species as well as hybrids / mutants / GMOs). The application is carried out both before the emergence of harmful plants and on the accumulated harmful plants (eg weeds, grass weeds, Cyperaceans or undesirable crops) regardless of the stage of sown / planted culture.

The invention also provides the use of the invention

Herbicide combination for selective control of undesirable

Plant growth, preferably in plant crops, especially in rice crops (planted or sown under 'upland' or 'paddy' conditions with Indica and / or Japonica species as well as hybrids / mutants / GMOs).

The herbicidal combination of the invention may be prepared by known methods, e.g. be prepared as mixed formulations of the individual components, optionally with other active ingredients, additives and / or customary formulation auxiliaries, which are then diluted with water for use in the usual way, or prepared as so-called tank mixes by co-diluting the separately formulated or partially separately formulated components with water become. Also possible is the staggered use

(Split application, splitting) of separately formulated or partially separated

formulated individual components. It is also possible to use the herbicides or the herbicide combination in several portions (sequence application), eg after applications as seed treatment or pre-seed (plant) treatment or pre-emergence, followed by post-emergence applications or early

Post-emergence applications followed by mid-late post-emergence applications. Preference is given to the common or timely use of the active ingredients of the respective combination, particularly preferably the common use.

The herbicides (A) and (B) may be used together or separately in conventional

Formulations can be converted, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, drug-impregnated natural and synthetic substances, Feinstverkapselungen in polymeric materials. Also to be mentioned are specific formulations for rice cultivation, such as e.g. Scattering granules, "jumbo" granules, "floating granules", "floating" -suspoemulsions which are applied via "shaker bottles" and are dissolved and distributed via the accumulation water. The formulations may contain the usual auxiliaries and additives.

These formulations are prepared in a known manner, e.g. by

Mixing the active compounds with extenders, that is to say liquid solvents, liquefied gases under pressure and / or solid carriers, optionally with the use of surface-active agents, ie emulsifiers and / or dispersants and / or foam-forming agents.

In the case of using water as extender, e.g. also organic solvents can be used as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene, alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as

Chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol and their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide or dimethyl sulfoxide, as well as water. Suitable solid carriers are: for example, ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite,

Montmorillonite or diatomaceous earth and ground synthetic minerals, such as

fumed silica, alumina and silicates; suitable solid carriers for granules are: e.g. crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite and synthetic granules of inorganic and organic flours and granules of organic material such as sawdust, coconut shells, corn cobs and tobacco stalks; suitable emulsifiers and / or foam formers are: e.g. nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, e.g. Alkylaryl polyglycol ethers, alkylsulfonates, alkyl sulfates,

It can be used in the formulations adhesives such as carboxymethylcellulose, natural and synthetic, powdery, granular or latex-shaped polymers, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and natural

Phospholipids such as cephalins and lecithins and synthetic phospholipids. Other additives can be mineral and vegetable oils.

The herbicidal activity of the herbicidal combination according to the invention may e.g. are equally improved by surface-active substances,

preferably by wetting agents from the series of fatty alcohol Polygiykoiether. The fatty alcohol Polygiykoiether preferably contain 10 - 18 C atoms in the

Fatty alcohol residue and 2 to 20 ethylene oxide units in the polyglycol ether section. The

 Fatty alcohol polyglycol ethers may be nonionic, or ionic, e.g. in the form of fatty alcohol polyglycol ether sulfates, e.g. as alkali salts (e.g.

Sodium and potassium salts) or ammonium salts, or as alkaline earth metal salts are used, such as C ^ / Cu-fatty alcohol diglykolethersulfat- sodium (Genapol ^® LRO, Clariant GmbH); See, for example, EP-A-0476555, EP-A-0048436, EP-A-0336151 or US-A-4,400,196 and Proc. EWRS Symp. "Factors Affecting Herbicidal Activity and Selectivity", 227-232 (1988). Nonionic fatty alcohol Polyglycol ethers are, for example, 2 - 20, preferably 3 - 15 ethylene oxide-containing (C1 ₀ - C ₈₎ -, preferably (C ₁₀ - C ₄₎ -Fettalkohol- polyglycol ethers (for example isotridecyl alcohol polyglycol ether), for example from the Genapol ^® X series, such as Genapol ^® X-030, Genapol ^® X-060, Genapol ^® X-080 or Genapol ^® X-150 (all from Clariant GmbH).

The present invention further comprises the combination of components (A) and (B) with the aforementioned wetting agents from the series of fatty alcohol polyglycol ethers which preferably contain 10 to 18 C atoms in the fatty alcohol radical and 2 to 20 ethylene oxide units in the polyglycol ether part and nonionic or ionic (eg as fatty alcohol polyglycol ether) may be present. Preferred are

It is further known that fatty alcohol polyglycol ethers such as nonionic or ionic fatty alcohol polyglycol ethers (e.g., fatty alcohol polyglycol ether sulfates) are also useful as penetration aids and enhancers for a variety of other herbicides (see, e.g., EP-A-0502014). The present invention therefore further includes the combination with suitable penetration aids and

Enhancers, preferably in commercially available form.

The herbicide combination according to the invention can also be used together with

Vegetable oils are used. The term vegetable oils refers to oils from oil-supplying plant species such as soybean oil, rapeseed oil, corn oil, sunflower oil, cottonseed oil, linseed oil, coconut oil, palm oil, thistle oil or castor oil, in particular rapeseed oil, and their transesterification products, e.g. Alkyl esters such as

Rapeseed oil methyl ester or rapeseed oil ethyl ester.

The vegetable oils are preferably esters of C10-C22, preferably C12-C20 fatty acids. The _do-C22 fatty acid esters are, for example, esters of unsaturated or saturated C 10 -C 22 -fatty acids, in particular with an even number of carbon atoms, eg erucic acid, lauric acid, palmitic acid and in particular C 18 -fatty acids such as stearic acid, oleic acid, linoleic acid or linolenic acid. Examples of Cio-C22-fatty acid esters are esters obtained by reacting glycerol or glycol with the Cio-C22-fatty acids, as they are, for example, in oils from oil-plant species, or Ci-C2o-alkyl-Ci ₀ C22 -Fatty acid esters, as can be obtained, for example, by transesterification of the aforementioned glycerol or glycol Cio-C22 fatty acid esters with d-C2o alcohols (eg, methanol, ethanol, propanol or butanol). The transesterification can be carried out by known methods, as described for example in Rompp Chemie Lexikon, 9th edition, Volume 2, page 1343, Thieme Verlag Stuttgart.

Preferred as C 1 -C 20 -alkyl-Cio-C ₂ -C 2 fatty acid esters are methyl esters, ethyl esters, propyl esters, butyl esters, 2-ethylhexyl esters and dodecyl esters. As glycol and

Glycerol Ci ₀ -C22 fatty acid esters are preferred, the uniform or mixed glycol esters and glycerol esters of Cio-C22 fatty acids, especially those fatty acids with even number of carbon atoms, such as erucic acid, lauric acid, palmitic acid and especially Ci ₈ fatty acids such as stearic acid, oleic acid,

Linoleic acid or linolenic acid.

The vegetable oils may be used in the herbicidal compositions of the invention e.g. in the form of commercially available oil-containing formulation additives, in particular those based on rapeseed oil such as Hasten® (Victorian Chemical Company, Australia, hereinafter referred to as Hasten, main constituent: rapeseed oil ethyl ester), Actirob®B (Novance, France, hereinafter referred to ActirobB, main constituent:

Rapeseed oil methyl ester), Rako-Binol® (Bayer AG, Germany, hereinafter referred to as Rako-Binol, main constituent: rapeseed oil), Renol® (Stefes, Germany, hereinafter referred to as Renol, vegetable oil constituent: rapeseed oil methyl ester) or Stefes Mero® (Stefes, Germany, hereinafter Mero called, main component:

Rapeseed oil methyl ester) may be included. In a further embodiment, the present invention also comprises the combinations with the abovementioned vegetable oils, such as rapeseed oil, preferably in the form of commercially available oil-containing formulation additives, in particular those based on rapeseed oil, such as ^Hasten® (Victorian Chemical Company, Australia, hereinafter referred to as Hasten, main constituent: rapeseed oil ethyl ester , hereinafter referred to), Actirob ^® B (Novance, France ActirobB, main ingredient:

Called Rapsölmethylester), Rako-Binol ^® (Bayer AG, Germany, referred to as Rako-Binol, main ingredient: rapeseed oil), Renol ^® (Stefes, hereinafter referred to Germany Renol, vegetable oil ingredient: Rapsölmethylester) or Stefes Mero ^® (Stefes, Germany, termed Mero called, main component:

Rapsölmethylester).

Dyes such as inorganic pigments, e.g. Iron oxide, titanium oxide, ferrocyan blue and organic dyes such as alizarin, azo and

Metal phthalocyanine dyes and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc can be used.

The formulations generally contain between 0.1 and 95 weight percent (wt%) of active ingredient, preferably between 0.5 and 90 wt%.

The herbicides (A) and (B) can be used as such or in their formulations also in admixture with other agrochemical active substances such as known herbicides for controlling undesired plant growth, e.g. for weed control or to control undesirable crops, e.g. Ready-to-use formulations or tank mixes are possible.

Also mixtures with other known active ingredients such as fungicides, insecticides, acaricides, nematicides, safeners, bird repellents,

Plant nutrients and soil conditioners are possible.

The herbicides (A) and (B) can be used as such, in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. The application is done in the usual way, eg by pouring, spraying, spraying, spreading. The active substances can be applied to the plants (for example harmful plants such as monocotyledonous or dicotyledonous weeds, weed grasses, cyperaceans or undesired crop plants), the seeds (for example grains, seeds or vegetative propagation organs such as tubers or

Shoot parts with buds) or the acreage (e.g., field soil), preferably on the green plants and plant parts and

if necessary, in addition to the soil. One possibility of the application is the common application of the active ingredients in the form of tank mixes, wherein the optimally formulated concentrated formulations of the individual active ingredients are mixed together in the tank with water and the spray mixture obtained is applied.

A common herbicidal formulation of the combination of the herbicides (A) and (B) according to the invention has the advantage of easier applicability, wherein the amounts of the components can be adjusted already in the optimal ratio to each other. In addition, the adjuvants in the formulation can be optimally matched to one another.

Biological examples

Post-emergence herbicidal action

method

Seeds or rhizome pieces mono- and dikotyler Schad- and

Crops were in, with sandy loam-filled peat pots (4 cm

Diameter) and then covered with earth. The pots were kept in the greenhouse under optimal conditions. In addition were

Harmful plants that are found in paddy rice cultivation, cultivated in pots with a water level 2 cm above the soil surface.

About three weeks after the beginning of the cultivation, the test plants were treated in the 1-3 leaf stage. The herbicides, component (A) formulated as

Suspension concentrate (SC) and component (B) formulated as wettable powder (WP), were sprayed either alone or in the combinations according to the invention with a water application rate of 600 l / ha in different dosages on the green plant parts. Subsequently, the pots were kept for further cultivation of the plants under optimal conditions in the greenhouse.

The visual evaluation of the herbicidal effects took place at intervals up to 21 days after the treatment. The evaluation was carried out on a percentage basis in comparison to the untreated control plants: 0% = no herbicidal action, 100% = complete herbicidal action = complete kill.

The percentage data from the treatments with the herbicides alone (=

Single applications) and with the combinations according to the invention (=

Mixtures) were used to calculate interactions according to Colby's method. If the observed effect values of the mixtures already exceed the formal sum of the values for the experiments with single applications, then they also exceed Colby's expectation value, which is calculated according to the following formula (see SR Colby, in Weeds 15 (1967) p 22):

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

Where:

 A, B = effect of component A or B in percent at a dosage of a or b g ai / ha (= grams of active ingredient per hectare).

 E = expected value in% at a dosage of a + b g ai / ha.

Results The combination of herbicides (A) and (B) according to the invention has been tested on a broad spectrum of important weed plants (weed grass / weeds / Cyperaceae) and useful plants: Triticum aestivum (TRZAS), Stellana media (STEME), Lolium multiflorum (LOLMU), Veronica persica (VERPE), Alopecurus myosuroides
