Known from documents D1 and D2 sulfanilamide General formulas 1 and 2 are for the most part satisfactory or good activity against a broad spectrum essential for agriculture monocotyledonous and dicotyledonous weed plants and also when specific conditions coltivirus active substances of General formula 1, 2 and 3 may be optimal struggle in agricultural practices, primarily against a wide range of monocotyledonous and dicotyledonous weed plants found in rice crops, however, the individual active substances are often not effective enough. In addition, in rice crops synergistically active combination shown in D3 or D4, are without much success. In any case, the probability of success in their application is not too high. In particular, this is due to the fact that the culture of useful plants, i.e. rice, also killed in large numbers when using the most well-known combinations, described in documents D3 or D4, and thus they are not suitable for use in crops of rice crops.

In addition, there are a number of monocotyledonous weeds, especially in crops of rice in the first place, such as Echinochloa crus galli, species of Ischaemum or Leptochloa that are not effectively be destroyed by means of one only known still herbicides or mixtures thereof, applied to Fig. Major weeds of rice in the first place, are such plants growing in Japan and Southeast Asia, as Sagittaria species, Eleocharis, for example, Eleocharis organs of plants in the soil and therefore more difficult to destroy, than weeds germinating from seed, as well as broad-leaved species, which, in General, form a wide spectrum of weeds that are difficult to effectively control.

In addition, there is growing tolerant species (including family or Cyperus Echinochloa), which are often no longer be destroyed by separate active substances, as well as using their traditional combinations.

In view of the above state of technology, the task was to create a mix with herbicide activity, practical to use and allows you to fight by one or more applications of herbicides with a broad spectrum of weeds or individual difficult to destroy weeds in rice crops. This mixture, consisting mainly of the well-known herbicide funds should help to close the so-called "gaps in activity and simultaneously to reduce the consumption of the individual active substances. In addition, there should be created a combination of herbicides, aimed at ensuring long-term effects. Finally, these combinations should also be able to effectively suppress the growth of weeds.

It has been unexpectedly OBN the kami of paragraph 1. Thus, the subject of this invention are herbicide products containing:

A) one herbicide active substance from the group of substituted vinylsulfonylacetamido General formula I and their salts, permitted for use in agriculture, that is valid and compatible salts

and C) at least one herbicide compound selected from the group of:

VA) herbicides selectively active in rice crops mainly in relation travalena plants,

b) herbicides selectively active in crops of rice, mainly against dicotyledonous weeds and weeds of the family of Cyperus,

Su) herbicides selectively active in crops of rice, mainly against weeds of the family of Cyperus and

Bd) herbicides selectively active in rice crops mainly in relation travalena and dicotyledonous plants and weeds from the family of Cyperus, provided that (i) products containing:

A’) one compound from the group of substituted vinylsulfonylacetamido General formula I and their salts, permitted for use in agriculture

in conjunction with:

In’) fenoxaprop, pendimethalin, nicosulfuron, EcoPro the means alkyl with 1-4 carbon atoms,

R2denotes alkyl with 1-4 carbon atoms, alkylthio with 1-4 carbon atoms or alkoxy with 1-4 carbon atoms, in which each residue may be substituted by one or more halogen atoms, or

R1and R2together form the group (CH2)mwhere m=3 or 4,

R3denotes a hydrogen atom or halogen,

R4denotes a hydrogen atom or alkyl with 1-4 carbon atoms,

R5denotes a hydrogen atom, a nitro-group, a cyano or one of the following groups: -COOR7-C(=X)NR7R8or-C(=X)R10,

R6denotes a hydrogen atom, halogen atom, cyano, alkyl with 1-4 carbon atoms, alkylthio with 1-4 carbon atoms or the group-NR11R12,

R7and R8the same or different and represent a hydrogen atom or alkyl with 1-4 carbon atoms, or

R7and R8together with the nitrogen atom to which they are linked, form a saturated five - or six-membered cyclic carbon ring,

R10denotes a hydrogen atom or alkyl with 1-4 carbon atoms, the latter optionally may be substituted by one or more halogen atoms, and

R11and R12the same or different and represent a hydrogen atom, alkyl with 1-4 carbon atoms is Ana, can form three-, five - or six-membered carbon cyclic or aromatic ring in which a carbon atom may be replaced by oxygen atom, bentazone, metsulfuron, triasulfuron, ioxynil, acetochlor, metolachlor, oxypertine or KIH-2023 as a separate herbicide funds will be excluded.

Using claimed in this invention combinations consisting of herbicide funds types a) and B), especially successfully manages to achieve suppression of growth is important for the practical needs of the spectrum of weeds, including also individual difficult to destroy. In addition, the use claimed in the invention combination, can significantly reduce the consumption of active substances included in the respective funds as components of the mixture, which increases their attractiveness to the user.

Finally, it has been unexpectedly discovered that the active substances in the composition of the combinations observed increased activity, higher than the expected value, due to the fact that herbicide means, as claimed in this invention, in a wide range of exhibit synergistic activity.

Along with this also appears vozmozhnostyej in claim in respect of the protection of the product) has in mind previously known combination, with these known combinations have not been given any conclusions about the suitability of combination drugs for their application in relation to rice.

In paragraph (i) in the claims specifically excluded previously known from document D3 combination consisting of one or more compounds of group a) and one compound of group b), and their scope is clearly different from the field of application of the combination, as claimed according to the proposed invention, as well as the subject of document D3 and the subject of the presented invention is clearly distinguishable from each other. While for combinations of herbicides, as stated in document D3 describes their use for crops or corn, for combinations of herbicides, stated in the proposed invention describes the use in rice crops.

Compounds of group (A) (General formula I) can form salts in which the hydrogen group-SO2-NH - substituted cations, permitted for use in agriculture. Such salts are, for example, metal salts, in particular alkali metal salts (e.g. sodium or potassium) or salts of alkaline-earth metals, and ammonium salts or salts of organic amines. Similarly, soleares the uly I. For these purposes, is suitable, in particular, hydrochloric acid, nitric acid, trichloroacetic acid, acetic acid or palmitic acid.

Especially preferred compounds of group a) are compounds in which the salt of the herbicide of formula (I) is formed by replacing the hydrogen-SO2-NH-group of the cation from the group of alkali metals, alkaline earth metals and ammonium, preferably sodium.

Since the compounds of formula I contain one or more asymmetric carbon atoms or else double bonds, which are not indicated separately in the General formula of these compounds, however, belong to type A. All of the possible stereoisomers defined by specific spatial formula, such as enantiomers, diastereoisomers, Z - and E-isomers encompassed by formula I and can be separated from mixtures of the stereoisomers by conventional methods or can be synthesized by using stereoselective reactions in combination with the use of stereochemical pure starting materials. These stereoisomers in pure form and mixtures thereof can, therefore, be applied according to the invention.

Vinylsulfonylacetamido General formula I, with iodine as a Deputy in the fourth position is x suitability as a synergistic component to herbicides, used in grain crops or corn is already known (compare D3), but their preferential suitability when used as components of the synergistic mixture with other herbicides used in rice crops, it is impossible to make an unambiguous conclusion. In particular, known in the available literature there are no indications that the combination of compounds of group AA), which is a relatively narrowly limited and well-defined group, which optionally can be in the form of salts of esters of 4-iodine-2-[3-(4-methoxy-6-methyl-1,3,5-triazine-2-yl)aridoculture]-benzoic acid, herbicides rice has such enormous implications for the fight against the most important weeds in rice crops. It is important also to bear in mind that the results of the use of any combinations of herbicides for corn or grain cannot be extrapolated to the activity of these combinations to rice. Even if you join the group AA) by themselves separately suitable for combating weeds in crops of rice, it is impossible to predict with high or even any significant probability of whether combination with other rice herbicides have actively increased ostatnim component combination is a compound A1) 4-iodine-2-[3-(4-methoxy-6-methyl-1,3,5-triazine-2-yl)aridoculture]-benzoic acid methyl ester:

Under certain circumstances, even more preferred component is the sodium salt of compound A1), which will be denoted as A1).

With regard to the effectiveness of a standard herbicide groups, again, you can pick up their activity in relation to subject the destruction of plant species.

Thus, one part of the herbicides of the group mainly active almost exclusively in relation to travalena plants (subgroup Ia)), the other part is active mainly against dicotyledonous plants and Cyparaceen (subgroup b)), the third part is active mainly against weed plants from the family of Cyperus (subgroup Su)), while the fourth group is active both in relation to travalena plants and dicotyledonous/Cyperus (subgroup Bd)).

In each case, however, the optimal range of actions stated in this invention, combinations of herbicides by complement and strengthen herbicide properties of the compounds of group A.

In view of the above forms of cooking herbicide is, as herbicide group means comprises one or more selectively active in rice crops against travalena plants herbicides from group VA), which include exhibiting herbicide activity anilide, in particular, chloroacetanilide, THIOCARBAMATE, quinoline carboxylic acid, cyclohexanedione and cyclohexandione, tetrazole, organophosphorus compounds, 2-(4-aryloxyphenoxy) propionic acid, preferably their esters, urea, pyridylcarbonyl, butyramide, mental-benzyl-esters and triazoles.

In particular, the object of the proposed invention are all commonly used connection options group, even if they are not listed specifically. As the optically active forms of the usual connections group, these compounds are also the subject of this invention, in some instances, these forms provide links (for example, fenoxaprop-ethyl and fenoxaprop-P-ethyl and so on).

The combination of active substances a+b, are active, that is, when the same degree of suppression of the growth of a weed when using claimed in this invention herbicide means, it becomes possible SN is both a useful, both from the economic and from an environmental point of view. The choice of the number of used components a+b, the ratio of components a+b and a temporal sequence of application as, for example, we choose the form of application will depend on a number of factors.

In this respect it is also important, including the type of mixture components, developmental stage of weeds or weedy grass, the spectrum of weed, subject to destruction, environmental factors, climatic conditions, soil conditions, and so forth.

In the most preferred according to the invention the form of the preparation, as claimed in this invention herbicide means are characterized in that they contain synergistically active combination of compounds of the formula I or their salts (compounds of group a) with compounds from group C. it is important to emphasize that even in combinations containing the necessary quantity or the weight ratio of compounds A:B, which have a synergistic effect directly observed not in all cases (for example, due to the fact that some compounds in the combinations are typically used in very different quantities or due to the fact that the suppression of the growth of a weed already have access to hetenyi, usually inherent synergistic activity.

Consumption of herbicide group a) in General ranges from 0.1 to 100 g AI/ha (AI = active ingredient, i.e. consumption is calculated based on the active active medium), preferably from 0.5 to 60 g AI/ha, particularly preferably from 2 to 40 g AI/ha

Consumption of compounds of group a) is, as a rule, the following values:

It is particularly unexpected was extremely low consumption of sulfanilamide General formula I of subgroups of AA). For example, the consumption of compounds A1) or A1) even more sharply reduced, in comparison with the known flow rate of the compounds A1) or A1), primeneniye to suppress the growth of weed plants in crops of cereals or maize. Such extremely low consumption at constant or improved suppression of the growth of weed plants in crops of rice could not be predicted on the basis of the existing state of technology.

Consumption of compounds of group is usually:

In combination, as claimed in this invention, the flow rate of the compounds of group (A) + compound of group b) is, as of provyedyenii And:in the combined herbicides as well as their applicable amount, as mentioned above, be varied within wide limits. The weight ratio of consumable components And In accordance with this invention are covered by the range of from about 1:20000 - up to 200:1.

Claimed in this invention the combination of active substances can be prepared in the form of a dry mixture of both components, then before you apply in the usual manner is dissolved in water, and in the form of so-called prepared in tank mixtures, obtained by joint dilution in water of the individual components of the formula.

Active funds types a) and b) can be produced in different forms, depending on the available biological and/or physico-chemical parameters.

As possible ready-to-use form, in particular:

Sprayable powders (WP), emulsifiable concentrates (EC), water-soluble powders (SP), water-soluble concentrates (SL), concentrated emulsions (EW), as malovodny and water-oil, sprayable solutions or emulsions, capsule suspensions (CS), dispersions on an oil or water basis (SC), suspension emulsions, suspension concentrates, powder tools (DP), oil-soluble solutions (OL), a means for treating, granules (GR) in the form of micro-granulate, sprayable granules and adsorption granules, granules, prednaznachennnoj (SG), dispersible in water granules (WG), ULV-forms, microcapsules and waxes.

Preferred among these forms are water-based, sprayable powder (WP), dispersible in water, the granules (WG), emulsifiable in water granulate (EC), suspension-emulsion (SE) and the oil suspension concentrates (SC).

These individual types of forms are in principle known and described, for example, in the following literature:: Winnacker-Kuchler, "Chemische Technologie" volume 7, C. Hauser Verlag Munchen, 4th edition 1986; Wade van Valkenburg, "Pesticide Formulations", Marcel Dekker, N. Y., 1973; K. Martens, "Spray Drying Handbook", 3rd edition 1979, G. Goodwin Ltd. London.

Important auxiliary components, such as inert materials, surfactants, solvents and other additives are also known and described, for example, in the following literature: Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd edition, Darland Books, Caldwell N. J.; H. v. Olphen, "Introduction to Clay Colloid Chemistry", 2nd edition, J. Wiley & Sons, N. Y.; Marsden "Solvents Guide, 2nd edition, Interscience, N. Y. 1963; McCutcheon''s "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N. J.; Sisley and Wood, "Encyclopedia of Surface Actcive Agents", Chem. Publ. Co. Inc., N. Y. 1964; Schonfeldt, "Grenzflachenaktive Athylenoxi-daddukte", Wiss. Verlagsgesellschaft, Stuttgart 1976; Winnacker-Kuchler "Chemische Technologie", volume 7, C. Hauser Verlag Munchen, 4th edition, 1986.

Based on this preparation, it is possible to get a combination with other active substances is or growth regulators, for example, in the form of finished form or in the form prepared in the tank mixtures.

Especially preferred according to this invention are combinations of herbicides, in which the compounds of formula I or their salts (compounds of group (A)) is mixed with one or more compounds of group b) in a form similar to that typically used in the processing plants. Such forms include water-soluble spray powder (WP), dispersible in water, the granules (WDG), emulsifiable in water granulate (WEG), suspension-emulsion (SE) and the oil suspension concentrates (SC).

The sprayed powder is a uniformly dispersible in water, the drug, which in addition to the active substances it contains inactive solvents or inert materials, surfactants, polar and/or nonpolar species (wetting agent, dispersing agent, for example polyoxyethylene alkyl phenol, polyoxyethylene the fatty alcohols and methamphetamine, sulfates polyglycolic ethers of fatty alcohols, alkanesulfonyl or alkylarylsulfonate, sodium salt ligninsulfonate acid, sodium salt of 2,2’-dinaphthyl-methane-6,6’-disulfonic acid, sodium salt dibutylaminoethanol acid ativnyh substances or active substance in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or an aromatic or non-aromatic hydrocarbons with a high boiling point, adding one or more surfactants, polar and/or nonpolar species (emulsifiers). As emulsifiers can be used, in particular, the following substances: calcium salt alkylarylsulfonates acid, such as dodecylbenzenesulfonate calcium or non-polar emulsifiers, such as polyglycolide esters of fatty acids, alkyldiphenylamine esters, polyglycolide ethers of fatty alcohols, the condensation product of propylene oxide and ethylene oxide (e.g., block copolymers), alkylpyridine, sorbitane esters of fatty acids, polyoxyethylenesorbitan esters of fatty acids or other polyoxyethylenesorbitan ethers.

Powder tools are obtained by grinding the active substances or substances with a finely powdered substance, such as talc, natural clays such as kaolin, bentonite and pyrophyllites, or diatomaceous earth.

Granules can be produced either by spraying the active substance or substances on the adsorption, granulated inert material or by applying active concentrates or mineral oils, on the surface of carriers such as sand, kaolinites or granulated inert material. Dispersible in water granulate receive, as a rule, conventional methods such as spray drying, spray granulation in fluidized bed granulation on a rotating disk, mixing in high-speed mixers and extrusion without solid inert material. In addition, the granules of the respective active agents can be obtained in the usual way in the production of granular fertilizers (optimally in the form of a mixture with fertilizers).

For agrochemical use the tool, as claimed in this invention contains, as a rule, from 0.1 to 99% by weight, preferably from 2 to 95% by weight, particularly preferably from 3 to 92% by weight of active substances of types a) and B), in addition to the usual tools.

The concentration of the active substances (A)+B) in the composition formula of the product can be varied. In sprayable powders the concentration of the active substances is, for example, about 10-95% by weight, the remainder is a normal part of the form. For emulsifiable concentrates, the concentration of active substances may be about 1-85% by weight, mostly 5-80% by weight. In powder form products contain then the Yeosu, mainly 2-20% by weight of active substances. For granular media such as dispersible granules, the active substance depends partly on whether the active compound is liquid or solid, and from what granulating auxiliary agent and filler are used in the manufacture of the product. As a rule, the content of the active substance dispersible in water granulate is 10-90% by weight.

Along with this, in the composition of active funds, if necessary, may include conventional binders, wetting agents, dispersing agents, emulsifying agents, impregnating agents, preservatives, antifreeze agents, solvents, fillers, colorants, carriers, defoaming means, means against evaporation, and tools that affect the pH value and the viscosity of the product.

Due to the relatively small expense claimed in the present invention, combinations of a+b, their compatibility, as a rule, is very good. In particular, using claimed in this invention combinations can achieve reduction of the absolute consumption of components in comparison with the flow rate when using a herbicide funds. To the Institute of combinations of herbicides, it is preferable to apply these components in the mixture or, in some cases, separately from each other together with protective agents or antidotes. As protective agents or antidotes for declared in this invention combinations can be used compounds are known, for example, from the following references: European patent application EP-A-333131 (ZA-89/1960), EPA-269806 (US-A-4891057), EP-A-346620 (AU-A-89/34951) and international application PCT/EP 90/01966 (WO-91/08202) and PCT/EP 90/02020 (WO-91/078474) or literature cited therein, and can also be obtained in accordance with the methods of manufacture. In addition, appropriate safeguards are described in European patent applications EP-A-94349 (US-A-4902304), EP-A-191736 (US-A-4881966) and EP-A-0492366 and the literature cited therein.

Protective measures may, depending on their properties be used to predsjedava processing of seed material of agricultural plants (seed dressing) or before sowing be sown in furrows or applied together with the herbicide mixture before or after germination of the plants. Predsjedava processing of crops is in the processing of the planting area before planting and processing planted, but not yet rising acreage.basiese in place of the mixture, and mix in a ready form.

The required number of protective measures may, depending on the respective application and apply herbicide to vary within wide limits and is generally from 0.001 to 1 kg, mainly of 0.005-0.2 kg of active substance per hectare.

Particularly effective in the scope of the presented invention and mainly suitable for use in crops of rice herbicide funds are obtained when used in conjunction with herbicides of group AA) in combination with the compounds of the group In the ethyl ester of 5,5-diphenyl-2-isoxazoline-3-carboxylic acid (= connection C3-1)) as a protective agent.

In this case, unexpectedly found that the combination consisting of compounds of group a) and the protective means C3-1), are in the rice crops increased, quasienergies activity even without the addition of other standard herbicides from the group). This additional effect is designed to further decrease the rate at constant effectiveness and breadth of product action. Mostly this effect is observed for combinations containing compounds from the group AA).

Particularly effective �p://img.russianpatents.com/chr/8727.gif">and C3-1, at least one connection group Century.

In this case, the protective means C3), especially C3-1, is especially effective due to the double effect. On the one hand, protective agent protects rice culture from unwanted damage by herbicides of group a, but on the other hand, provides a synergistic enhancement of activity of certain herbicides from the group (A) in relation to weeds.

Of particular interest in the framework of the present invention is the use of herbicide products containing in its composition compounds of group a) in an amount of from 0.5 to 60 g AI/ha in combination with protective agents C3) in an amount of from 10 to 200 g AI/ha

Preferred are also herbicide funds, with the weight ratio of the compounds of groups A) to compounds C3) in the range from 1:400 to 20:1, mainly from 1:200 to 10:1.

Especially preferred within the scope of the presented invention is also the use of herbicide products containing in its composition the compound of group (A), mainly compounds A1) or A1), in an amount of from 0.1 to 10 g AI/ha in combination with the compound C3) in an amount of from 10 to 100 g AI/ha

Before using the tool described composition in STD is La sprayable powders, emulsifiable concentrates, dispersions and dispersible in water and granules. Funds in powder form, in the form of various granules and sprayable solutions before use, usually no longer mixed with other inert materials.

The object of the present invention is also a method of using these funds to combat undesirable weedy plants, which is characterized by the fact that these plants or the crop area is treated with the necessary amount of herbicide mixtures, representing claimed in this invention the combination of active substances (A)+B). Active means can be processed in the plants, plant parts, plant seeds, and acreage.

In the most preferred version of application consumption of compounds of formula (I) or their salts (compounds of group (A)) is from 0.1 to 100 g AI/ha, preferably from 0.5 to 60 g AI/ha, particularly preferably from 2 to 40 g AI/ha, while the flow rate of the compounds of the group is from 1-5000 g AI/ha Preferred is the use of active substances of types a) and b) simultaneously or separately in a weight ratio of from 1:20,000 to 200:1. In addition, especially preferred is together the different active substances in the optimal composition together bred in the tank with water, and the resulting broth is used for the treatment of crops.

Since compatibility with agricultural plants claimed in this invention combinations extraordinarily good at both very high degree of suppression of the growth of a weed, these tools can be considered as a means of selective action. In a preferred embodiment of the herbicide tool claimed in this invention combinations of active substances used to selectively suppress the growth of unwanted plants.

Especially preferred is the method of election fight against weed plants in crops of rice with application of herbicide means, as claimed in this invention, the composition of which is as a component of group b) are compounds of subgroups with VA) on Bd).

Components of group a) when a single application in rice crops destroyed quite a wide range of annual and perennial weeds, weed grasses and weedy plants from the family of Cyperus.

However, the range of action of the compounds of group (A) when used in combination with the described in this invention the compounds of group b) was significantly expanded.

Of takii combat travaline weeds in rice crops.

Components group 33b) from the group b) mainly complement and enhance the activity of the compounds of group (A) in rice crops, mainly in the fight against weed plants from the family of dicotyledons, and also, to a considerable extent, in respect of a weed from the family of Cyperus.

Compounds of the subgroup Su) (for example, connection B40) are means with a wide range of actions that can be applied to improve the activity of the compounds of group (A) predominantly in the fight against weed plants from the family of Cyperus, mainly in rice crops.

Similar spectrum of effects on weed plants have compound from the group of sulfanilamide (connection B) V)), and their consumption is still about an order of magnitude lower.

Depending on the nature of the composite component group) declared in the present invention, combinations of herbicides can be successfully used for controlling undesirable weedy plants in transgenic rice crops.

The growth of many hard-to-destroy perennial weeds that grow from the stems, roots or other vegetative organs of plants, is also well suppressed such combinations of active substances. It does not matter whether the substances before sowing, when predsjedava the processing of crops or during post-harvest handling.

Amongst the monocotyledonous weed species declared herbicide tools work well against species such as Echinochloa, as well as annual plants of the family Cyperus, and among perennial plants inhibit the growth of resistant species from the family of Cyperus.

The growth of weedy plants that appear in the rice crops under specific culture conditions, for example species such as Sagittaria, Alisma, Rotala, Monochoria, Eleocharis, Scirpus, Cyperus, and so forth, perfectly suppressed by using claimed in this invention combinations of active substances.

If declared in this invention herbicide means to apply before the germ of a weed, or the emergence of a weed completely suppressed or weed growth stops at an embryonic stage, then within three to four weeks all the weeds completely perish.

- % The post-harvest processing of crops after treatment is also observed rapid and abrupt cessation of growth of the weeds. Weed plants stop at the stage of growth in which they were at the time of application or die after a certain time more or less quickly. Thus, when using the new herbicide means, as claimed in this invention, it is possible quickly and for a long time to eliminate competition for agricultural plants from harmful weeds.

Although stated in this invention herbicide funds are expressed herbicide activity against mono - and dicotyledonous weed plants, damage to agricultural plants are very small or missing altogether. For this reason, declared herbicide means very effective, especially in rice crops, to selectively suppress the growth of unwanted plants.

Specifically, to weed the plants, in growth suppression aimed the tool, are, as already mentioned, in the first place, herbaceous, dicotyledonous and /or species of the family Cyperus easy destruction by other means. Mainly the effects claimed in the present invention, combinations of the compounds of groups A) and b), directed hinochloa also it suppresses Bermuda, Echinochloa chinesis, Echinochloa crus galli, Leptochloa chin. /fil., Paspalum dis., Brachiaria platyphylla, species Digitaria, Ischaemum, Leersia hexandra, Oryza sativa (red rice), Cenchrus echinatus, Rottboellia exaltata, Leersia, and the like, among herbaceous plants; Monochoria vag., Potamogeton dis., Rotala indica, Marsilea crenata, Ludwigia ad., Salvina mol., Ipomoea, Sesbania ex., Heteranthera, Commelinia, Butomus, Aeschynomene, Alisma plantago, Eclypta, Murdania, Xanthium species Alteranthera, Spenodea zey., Sagittaria species luncus, Polygonum, Ammania ind. among the weeds: Cyperus diff., Cyperus iria, Fimbrisrylis litt., Cyperus ferax, Cyperus esculents among annual plants of the family Cyperus and Eleocharis species, Scirpus species, Scirpus mucronatus and Cyperus rotundus among perennial plants in the family Cyperus.

In General we can say that in case of joint application of sulfanilamide with the General formula I and /or their salts together with one or more active substances from groups A) heightened (= synergistic) effect. Thus the activity of the combination is higher than the total activity of individual products when applied separately.

These effects allow:

to reduce the number of consumable components,

to ensure the impact on the broader spectrum of weeds and weed grasses,

to provide faster and more reliable effect on weeds,

to provide longer lasting effects on weeds,

to ensure complete is siriti timing of application of the active substances in combination.

These properties are useful for practical purposes fight against weed plants crops allows to quantitatively and qualitatively improve the efficiency and reliability suppress the growth of unwanted weed. Technical standard describes the properties claimed in the present invention combinations significantly surpassed.

In addition, as claimed in this invention combinations allow you to deal effectively with weedy plants, especially resistant to other drugs.

2. Biological examples

The following examples are designed for testing in the greenhouse and partly for field trials.

i) Effects on weeds when predsjedava tillage

Seeds or vegetative organs of mono - and dicotyledonous weed plants are placed in plastic cups with a diameter of 9 cm with sandy loam soil and the top covered over with earth. Weeds found in rice cultivation, cultivated in a rich soil water, for this purpose, the glasses are filled with water so that the water level was a few millimeters above the soil surface. Claimed in this invention the combination of active substances, made in the form of wettable powders or emulsion concentrates, as well as in a parallel experiment, the corresponding individual active substances in the form of an aqueous suspension or as an emulsion was applied to the soil surface in Sundry disablity, which supported good growth conditions for the weeds (temperature, humidity, water supply). After the time of the experiment 3-4 weeks is visual inspection of the experimental plants and the comparison with the results of the control experiment, in which plants were not treated with herbicides. For statistical reliability, the experiments were repeated two to five times. Claimed in this invention herbicide tool showed good herbicide activity against a broad spectrum of weed grasses and weeds when predsjedava tillage.

ii) Effects on weeds in post-harvest processing

Seeds or vegetative organs of mono - and dicotyledonous weed plants are placed in plastic cups with sandy loam soil, backfilled above the ground and then placed in a greenhouse, in which supported good growth conditions for the weeds (temperature, humidity, water supply). Weeds found in rice cultivation, cultivated in a rich soil water, for this purpose, the glasses are filled with water so that the water level was two inches above the soil surface. Three weeks after POSELENIE combination of active substances, composed in the form of a sprayable powders or emulsion concentrates, as well as in a parallel experiment, the corresponding individual active substances in different dosages based 300-600 l/ha was sprayed onto the green parts of plants and in 3-4 weeks, during which the experimental plants were kept in the greenhouse under optimal growth conditions (temperature, humidity, water supply), is visual inspection of the experimental plants and the comparison with the results of the control experiment, in which plants were not treated with herbicides. For rice and weeds found in rice cultivation, the active tool is also directly added to water for irrigation (similar to the so-called application in the form of granulate or sprayed on plants and in water for irrigation. For statistical reliability, the experiments were repeated two to five times. Claimed in this invention herbicide tool showed good herbicide activity against a broad spectrum of essential agricultural weeds and weed grasses.

iii) Examples of assessment of combination effects

For the assessment of combination effects, the total impact is that combination show a higher degree of activity, than the total activity of the individual components.

In cases where the effect was less marked, according to the Colby formula calculates the expected value, which is compared with the empirically obtained results. Theoretically calculated value of the expected degree of activity of the corresponding combination is determined by the formula Colby (S. R. Colby: “Calculation of synergistic and antagonistic responses of herbicide combinations”, Weeds 15 (1967), S. 20-22).

The calculation formula for combinations, consisting of two components, as follows:

E=X+Y-(X-Y)/100,

as for the calculation for combinations consisting of three herbicide means,

E=X+Y+Z+(XYZ)/10000-(XY+XZ+YZ)/100

where X = the percentage of damage from exposure to the herbicide (A) when the value of consumption x kg AI/ha;

Y = percentage of damage from exposure to the herbicide At the rate in kg AI/ha;

Z = the percentage of damage from the impact of another herbicide With flow z kg AI/ha;

E = the expected value, i.e. the expected percentage of damage from exposure to herbicides a+b (or a+b+C) at a flow rate of x+y or x+y+z) kg AI/ha

In which case the synergies can say, if the empirical value is larger than Teoreticheskie also to make a comparison on the total formula.

In most cases, however, a synergistic increase in activity is so great that criterion Colby can be waived; because the activity of the combination is significantly greater than the formal (numeric) the sum of the activities of the individual active substances.

It should be particularly emphasized that in determining the presence of synergistic effects for the active substances it is necessary to consider that the consumption of the individual active substances varies greatly. Thus, it makes no sense to compare the activity of the combination of active substances and certain active substances at the same flow rate. For declared in this invention flow values for the active substances are characterized by the fact that the application of funds in these quantities is observed or non-linear increase in the activity than the sum of the activity of the individual active substances, or while maintaining the same activity can reduce the consumption of individual components.

The results of the biological tests are presented in tables 1-22.

The examples show that the effects of the individual active substances of certain weeds are amenable to effective destruction of only the high-dose herbicide. Components, prakticheskoe interest. Only when the joint application of the active substances is possible to achieve a good effect against all the tested weed species. This additional activity of the mixture exceeds the total activity of its individual components, which significantly reduces the consumption of active substances to achieve the desired level of suppression of weed growth. Owing to the above effects, it is possible to significantly expand the range of impacts of these herbicide funds.

Compatibility herbicide funds from agricultural plants, as measured by the degree of damage to plants has not changed for the worse, i.e. the mentioned combination herbicide funds can be considered as a means fully electoral impact.
