The invention relates to agriculture, namely to chemical herbicides for controlling undesirable vegetation in crops of cereals.

It is known the use of derivatives of the sulfonylureas, such as chlorsulfuron (Cortes, SP 750 g/kg), metsulfuron-methyl (Laren, SP 600 g/kg), tribenuron-methyl (Granstar, STS 750 g/kg), triasulfuron (Logran, EDC 750 g/kg) and the other for control of weeds in crops of cereals (List of pesticides and agrochemicals permitted for use on the territory of the Russian Federation, 2003 [1], str, 240, 253, 253, respectively, and Melnikov N.N., Novozhilov C.V., Belan S.R. Pesticides and plant growth regulators, Meters, Chemistry, 1995 [2], str, 107, 156, 156, respectively). In parentheses after the name of the sulfonylurea given the trade name of the drug, preparative form and content of active substance (DV) in the preparative form.

Due to the poor solubility of the sulfonylureas in water at the processing plants they are used in the form of wettable powders (SP), for example Cortez JV; Laren JV, or water dispersible granules (EDC), or dry flowable suspensions (STS), such as Logran EDC; Granstar STS, with water to form aqueous suspensions [2, p.24, 25].

For the formation of a stable suspension, the particle size of the active ingredient in preparative form should not exceed 3 μm, and it is necessary to introduce special the ingredients (dispersers, fillers, binders and other)

Therefore, to obtain herbicide formulations in the form of JV, EDC or CTC requires a number of additional physical and chemical processes on the preliminary grinding, the subsequent mixing of the sulfonylureas with ingredients or pelleting powdered drugs on the media, etc. (LNV, Chemistry and technology of pesticides, M., Chemistry, 1974, p.29, 32-35).

Also, when grinding and mixing dry ingredients due to dust may contaminate the environment with biologically active substances. Therefore, for the organization of such facilities requires the creation of a guaranteed protective structures. All this significantly complicates the process of making preparative forms and leads to a higher cost of production.

The use of these sulfonylureas in the form of suspensions significantly slows down the speed of transport of solid particles of active ingredient herbicide composition of the liquid phase in the plant, resulting in reduced herbicide activity of the composition, increase of residual aftereffect and, as a consequence, the restriction of positoovity treated cultures (1, str, 271, 253; 2, str).

The shortcoming of the above herbicide compounds is their high rate of consumption and, as a consequence, in the high hectare cost of processing.

So, for example, norms of consumption of these drugs are: 6-8 g/ha (4,5-6,0 g chlorsulfuron 1 ha), 8-10 g/ha (4,8-6,0 g metsulfuron-methyl-1 ha), 15-25 g/ha (11,2-18,8 g tribenuron-methyl 1 ha), 6.5 to 10 g/ha (4.9 to 7.5 g of triasulfuron 1 ha).

To overcome these shortcomings of widely used herbicides with two or three of the active ingredient and with less consumption norms of the sulfonylureas, such as Cowboy [1, pp.232], Dipesan [1, str], Fenves [1, str], Grinch plus, Gran-D [1, str], Cross [1, str], Cross + Granstar [1, str], the Tresor M [1 str] and others

When sharing two DV consumption norms of the sulfonylureas are: Cowboy 150-190 ml/ha (2,6-3,3 g chlorsulfuron 1 ha), Dipesan 140-200 ml/ha (2,6-3,8 g chlorsulfuron 1 ha), Fenves 1,3-1,5 l/ha (3.0 to 3.5 g chlorsulfuron 1 ha), Grants plus 1.8 g of metsulfuron-methyl-1 ha, Gran D of 1.8 g metsulfuron-methyl-1 ha, Cross 120-150 ml/ha (5,6-7 g chlorsulfuron 1 ha), Cross + Granstar 7.5 g tribenuron-methyl 1 ha, the Tresor M 4,3-5,2 g triasulfuron on 1 hectare

However, the inclusion of herbicide second LW significantly increases the cost of the herbicide in General and the value of a hectare of rules.

So, for example, the rate of flow of dicamba and chlorsulfuron herbicide Cowboy, respectively 55,2 to 69.9 g/ha and 2.6 to 3.3 g/ha At the same time in a single-label herbicide Cortes rate p is DV is only 4.5-6.0 g/ha chlorsulfuron. The cost of a hectare norms of herbicides in the calculation of the far East and consequently is 27,3 and 3.3 rubles/ha However, the herbicide Cortes and other one-component compositions as described above, are not sufficiently high biological activity compared to multi-component compositions.

Therefore, the enhancement of herbicide action of sulfonylureas with simultaneous substantial decrease in the consumption rate of the active component and the value of a hectare consumption rates of herbicide preparation, as well as residual aftereffect in positoovity treated cultures is an actual and important task, the solution of which the present invention is directed.

The closest in technical essence and the achieved result of the present invention is a herbicide composition based on ammonium salts 2-methoxy-3,6-dichlorobenzoyl acid (dicamba) and sulfonylurea with the addition of surface-active agent (surfactant) and water [RF Patent №2208930, class A 01 N 47/40, A 01 N 47/36, A 01 N 25/30, publ. 2002].

In accordance with this patent, the increased biological activity of the herbicide composition is achieved by introducing it as a surfactant polyoxyethylene of dialkylamino 0.1 to 45 wt.% and monoalkyl ether of polyethylene glycol in an amount of 0.1-50 wt.%. Increasing herbicide action is achieved by b is more high speed penetration of the active ingredient in weed.

The disadvantage of this herbicide composition are the high consumption rate in the far East and, as a consequence, high-hectare cost of cultivation of crops and the low stability of the sulfonylureas, included in the formulation, during storage, which affects its herbicide activity. In accordance with the requirements of Goshinkwai expiration date herbicide formulations should be not less than 2 years.

In addition, when sharing the recipe dicamba and sulfonylurea limited use as surfactants polyoxyethylene of dialkylamino due to the negative effect of this surfactant on the stability of the formulation (sulfonylureas) during storage.

It is also known that the monoalkyl ethers of polyethylene glycol (for example, oxonol KD-6) are used as foam stabilizers [Surfactant. The Handbook. L., Chemistry, 1979. Edited Art and Gamgebeli, str]. Therefore, the disadvantage of this composition, containing significant amounts of surfactants in the presence of water, is also a significant expansion with the formation of stable foam in the preparation, packing and practical application that may lead to the release of biologically active substances into the environment, which is unacceptable.

Given the shortcomings of much of the level is t the main positive quality of this herbicide.

Also known final form of the herbicide composition containing separately packaged dry and liquid composition. The dry composition contains a sulfonylurea selected from the group: Granstar, clay, diethylethanolamine salt chlorsulfuron, potassium salt of chlorsulfuron. The liquid composition contains, wt%:

Ethoxylated alkyl phenols and alcohols17-22;
The sulfonic acid or calcium lignosulfonate1-5;
Water5-10;
Kerosene100

Before applying to dry compositions on the basis of sulfonylureas in deprotonated form (in salt form) is added to the liquid composition (EN 2173518, class a 01 N 47/36, 25/30, 25/02, publ. 20.09.2001).

The disadvantage of this arrangement is the need for the process of formulation of the herbicide in dry form. When mixing the dry ingredients of the herbicide possible local inhomogeneities, and admission into the environment (atmosphere and waste water) biologically active substances.

Taking into account the aforementioned disadvantages of the known herbicide composition and final forms herbicide composition task, the solution of which the invention is directed, is to reduce the rate of herbicide composition, increasing its stabil the surface during storage, and the improvement of environmental safety of the composition during its preparation, packing and practical application.

This task is solved in that the herbicide composition containing at least one derivative of the sulfonylureas, polyoxyethylene dialkylamino formula: RRN(CH2CH2O)xN, where R=C2-C8-alkyl, x=1-6, and water, wherein these components contains the following ratio in wt.%:

The sulfonylurea0,7-17,3
Polyoxyethylene dialkylamino0,6-78,1
WaterRest

moreover, the molar ratio of sulfonylureas and polyoxyethylene of dialkylamino is from 1:2 to 1:27. In addition, herbicide composition further comprises 2-methoxy-3,6-dichlorobenzoyl acid (dicamba) to 31.1%, monoalkyl ether of polyethylene glycol of the formula: R1(OCH2CH2)yOH, where R1=C6-C12-alkyl, y=4-8 up to 88.3 wt.% and polymethylsiloxane or silicone antifoam 0.1 wt.%.

This task is solved by the fact that the final form of the herbicide composition comprising separately packaged compositions of dry and liquid components that are mixed lane is on the application of the herbicide composition, according to the invention, the dry composition contains at least one derivative of a sulfonylurea or their mixture, and the liquid composition contains polyoxyethylene dialkylamino formula: RRN(CH2CH2O)xN, where R=C2-C8-alkyl, x=1-6, and water in the following ratio of components, wt.%:

Polyoxyethylene dialkylamino0,6-80,0
WaterElse,

but not less than 10,0

moreover, the mass ratio of dry and liquid compositions is from 1:4.8 to 1:141,8, and the molar ratio of sulfonylurea derivatives contained in the dry composition, and polyoxyethylene of dialkylamino contained in the liquid composition ranges from 1:2 to 1:27. In addition, the liquid composition may further contain 2-methoxy-3,6-dichlorobenzoyl acid (dicamba up to 32 wt %, monoalkyl ether of polyethylene glycol of the formula: R1(OCH2CH2)yOH, where R1=C6-C12-alkyl, y=4-8 and/or up to 90 wt.%, and polymethylsiloxane or silicone antifoam 0.1 wt.%.

Sulfonylureas preferably used in the form of two-component mixtures in a mass ratio of 1:1-4 or in the form of three-component mixtures in a mass ratio of 1:1:1.

Of the derivatives of the sulfonylureas is sportsouth chlorsulfuron, metsulfuron-methyl, tribenuron-methyl, triasulfuron, thifensulfuron-methyl, amidosulfuron, chlorsulfuron, sulfometuron-methyl, enculture-methyl, nicosulfuron, pyrazosulfuron-ethyl, primisulfuron, flazasulfuron, atomiculture-methyl, rimsulfuron, triflusulfuron-methyl and other

The proposed herbicide composition is used as follows.

Directly before applying the herbicide composition to a liquid composition at room temperature (15-25° (C), portions with stirring (manually) add a solid composition and continue stirring for 2-3 minutes, until complete dissolution of the crystalline phase.

To give a liquid composition required viscosity during storage at low temperatures (down to minus 30° (C), as well as for a better solution in it proizvodnyh sulfonylureas (dry composition) before using the water content in the liquid composition should be at least 10%, mostly 20-30%.

When the molar ratio of sulfonylureas and polyoxyethylene of dialkylamino from 1:2 to 1:1 increases the duration of the dissolution of the sulfonylureas to 3-15 minutes, and when the molar ratio is less than 1:1, there is incomplete dissolution of sulfonylureas.

The analysis of the examples illustrating the invention, shows that in the presence of the proposed defoamers (table 5) foam in herbicide compositions decreases from 4-4,2 to 1.2 to 0.4, i.e. 3.5-10 times at a concentration of polymethylsiloxane from 0.01 to 0.1%, and from 4-4,2 to 0.14 and 0.06, i.e. in 28-66 time when the concentration of the silicone antifoam 0.01 to 0.05%.

When used as antifoam fatty alcohols C8-C10the foam decreases with 4-4,2 to 2.7-1,2, i.e. only 1.5-3.3 times at a concentration of fatty alcohols C8-C100,3-3,5%.

Proposed herbicide formulations on the basis of the sulfonylureas, polyoxyethylene of dialkylamino and monoalkyl ethers of polyethylene glycol (A1-A4) are stable during storage (table 6).

At the same time, herbicide compositions And11-And14obtained by mixing the compounds No. 1 (dry composition) and No. 2 (liquid composition) of the respective herbicide formulations A1-A4are extremely unstable and depending on the content monoalkyl ether of polyethylene glycol in PR the cases from 40-90 wt.% there is decomposition of the sulfonylureas from 63 to 94%.

Proposed herbicide compositions based on a mixture of two of the sulfonylureas, polyoxyethylene of dialkylamino and monoalkyl ethers of polyethylene glycol (A6,1And6,2) are also stable during storage (table 7).

At the same time, herbicide compositions In2,1and In2,2obtained by the mixture of compounds 1 and 2 herbicide formulations And6,1And6,2, respectively, are unstable in storage, and they observed the decomposition of chlorsulfuron 79%, chlorsulfuron at 92-95%.

Proposed herbicide formulations on the basis of sulfonylurea and dicamba, polyoxyethylene of dialkylamino and monoalkyl ethers of polyethylene glycol (a5,1And5,2) stable during storage (table 7).

Known herbicide formulations B1,1In1,2(prototype) unstable. The degree of decomposition of chlorsulfuron during storage is 60-76%.

Finally, the proposed herbicide formulations on the basis of the sulfonylureas, dicamba and polyoxyethylene of dialkylamino used as the complexing agents and surfactants (A7,1, A7,2stable when stored.

Opposite the well-known herbicide formulations In3,1and In3,2(prototype) unstable. The degree of decomposition of sulfonylureas is 48-52%.

Therefore, proposed is herbicide compositions unlike the prototype may use polyoxyethylenic of dialkylamino as surfactants in conjunction with sulfonylureas.

Comparative analysis of herbicide activity proposed compositions A1-A4and analogues (known compounds) (table 8) shows that when using the proposed formulations for the treatment of crops significantly reduced the consumption rate of the sulfonylureas (3-6 times).

From the data shown in table 9, it follows that during storage the proposed structures on the basis of sulfonylureas, dicamba, polyoxyethylene of dialkylamino and monoalkyl ethers of polyethylene glycol (A5,1And5,2retain high herbicide activity.

Similar compositions (B1,1In1,2prepared in accordance with the patent of the Russian Federation No. 2208930 (prototype), you lose herbicide activity by 15-18%, which is a consequence of their instability during storage.

Even more significant reduction in herbicide activity is observed during storage herbicide formulations And11-And14on the basis of the sulfonylureas, polyoxyethylene of dialkylamino and monoalkyl esters of polyethylene glycol, which is prepared by mixing the compounds No. 1 and 2 of the respective herbicide formulations A1-A4.

As follows from the data given in tables 8, 9, loss of herbicide activity are 52-67%, which is a consequence of their extremely high volatility in p is acesse storage.

A similar pattern is observed for the herbicide compositions that use a mixture of two of the sulfonylureas (A6,1And6,2B2,1In2,2). In this case, the loss of herbicide activity are 28-31%.

From the data in table 9 also shows that after storage the proposed composition of A5,1And5,2exhibit higher herbicide activity (21-25%) compared to industrial design herbicide Cowboy and proposed structures And6,1And6,2have herbicide activity on 29-33% higher compared to the industrial design of herbicide Cross, which is also a consequence of the lack of stability is known compositions during storage.
