The invention relates to agriculture, namely to chemical herbicides used for weed control.

The aim of the invention is to increase the efficiency of the known herbicides based on 2,4-dichlorophenoxyacetic and 2-methoxy-3,6-dichlorobenzoyl acids. The composition contains additional N-[4-methyl-6-methoxy-1,3,5-triazinyl-2)aminocarbonyl]-2-chlorobenzenesulfonamide, N,N,N',N'-tetramethylmethylenediamine and n-dodecylamine.

As surface-active substances (surfactants) can be used ethoxylated projournal-active substances, physiologically compatible with these operating principles.

The mechanism of action used in the surfactant composition should be effective agents of fetotoksicheskoe actions, providing good wetting, penetration of the herbicide into the tissue, its transport through the body of plants and effective interaction with the tissues of weeds, in the aggregate, causing herbicide effect.

The invention is illustrated by the following examples (see tab.1).

Example 1. In a reactor with a stirrer was placed a 21.5 g of water, of 14.7 g of N,N,N',N'- tetramethylmethylenediamine (TMDA) and under stirring load of 30 g of 2,4-dichlorophenoxyacetic acid (2,4-D), 2.0 g of 2-methoxy-3,6-dichlorobenzoyl acid (dicamba) and 0.1 g of N-[(4-methyl-6-methoxy-1,3,5-triazinyl-2)aminocarbonyl]-2-chlorobenzenesulfonamide (chlorsulfuron) and 2.0 g of n-dodecylamine. The reaction mass is stirred for 1 h at a temperature of 45oC. To the resulting composition add to 27.7 g of tween-20 and 2.0 g of n-dodecylamine and stirred for 30 min to obtain a homogeneous mass. Get transparent drug light brown color with a faint amine odor. In the resulting herbicide composition of existing components 2,4-D : dicam of 21.6 g of water, 24.4 g TMDA, 24 g of 2,4-D acid, 2 g of dicamba, 0.4 g of chlorsulfuron, stirred at a temperature of 45oWith, then add to 26.0 g of tween-40 and 1.6 g of n-dodecylamine. Receive herbicide composition where the active components 2,4-D : dicamba : chlorsulfuron are in the ratio 12:1:0,2.

Example 7. Aqueous solutions of drugs in examples 1-6 treated crops of spring wheat varieties Moscow 35, weedy annual and perennial weeds. The main weeds: cleaver, woodlouse, bindweed, Thistle field, Lactuca tatarica. The processing of the drug in the tillering stage, while the height of the weeds 10-20 cm, accounting contamination - 20 days after treatment to reduce fresh weight of weeds in comparison with the control. The results are presented in table.2.

The proposed structure of the activity is significantly superior to known drug metopen operating principles of which are 2,4-D and dicamba in the ratio of 10:1 to 15:1 (RF Patent 1681808 class. a 01 N 39/04 //(a 01 N 39/04, a 01 N 37/10); Davydov, A. M. Retrospective improve domestic herbicides for grain and tilled crops. Ufa, 1998, s.).

Are given in table. 2 data indicate a synergistic interaction of 2,4-D acid, dicamba and chlorsulfuron performance ratio(12-18):1:(0,046-0,23).

Tactile components of the composition, and with a known composition.

Example 8. Aqueous solutions of drugs in examples 1-6 treated crops of barley, weedy annual and perennial dicotyledonous weeds, dominated by white pigweed, Amaranthus thrown, field field, pikulnik ordinary, cleaver, lnjanka ordinary, bindweed, Thistle field. Spraying the drug in the phase of tillering barley, accounting for contamination in a month after treatment to reduce fresh weight of weeds in comparison with the control. The results are presented in table.3 (left and middle columns).

Are given in table.3 the results show that the proposed composition in a month after treatment has higher functional activity than the known composition.

Example 9. In addition to example 8 in the same field are counted debris after 2 months of treatment. The results are presented in table.3 (two right columns). The difference in activity between the second and first terms of the account indicates the prolonged nature of the action proposed composition as a distinctive sign.

Example 10. Another distinctive characteristic of the proposed herbicide status at the time poshagovoe processing, but in connection with the removal of rooted weeds can then in abundance to emerge from the germinating seed in the form of a "second wave" of weeds. The rapid growth of many of them, especially involving bedstraw, contributes to the lodging of grain for harvesting, which makes it impossible for direct combining. Thereby increase the costs of separate cleaning, increase the harvesting time, reduces the quality and quantity of the harvest.

Accounting rising again weed is played on a field of spring wheat treated with the proposed herbicide composition at the tillering stage, two months after the above processing. The results are shown in table.4.

From the data table. 4 it follows that only the proposed structure reliably prevents the emergence of a "second wave" of weeds.

Example 11. The combination of useful properties of the proposed structure, which distinguishes it from known compounds, has a positive effect on the value of crops, in this case wheat (table.5).

From table.5 it follows that the use of the proposed structure provides the greatest yield increase compared to its individual components and with a known composition.

Example 12. One of the negative effects of mn is full-time persistence in the soil. The consequence of this negative phenomenon can be reduced seed germination, and thus the yield of subsequent crops. A distinctive feature of the proposed structure is the absence of such negative side effects.

Compares the residual phytotoxicity soil depth of 10 cm, measured from the surface, with plots Poshtova treated with effective doses of the proposed structure, on the one hand, and chlorsulfuron in the middle, usually the recommended dose (25 g/ha), on the other hand. Phytotoxicity of soil samples is determined by sowing seeds of sugar beet is one of the most sensitive crops to soil, taken from the relevant sections in 4 months after conducting herbicide treatments of wheat. The results are presented in table.6. They clearly indicate the absence of the dangerous aftereffects of the proposed structure on the subsequent crops.

Thus, valuable property proposed composition drastically limit the germination of weeds "second wave" (example 10) is combined with the security of its regulated use for subsequent crops.

Not the least in importance is stoimosti composition in water. In this he differs from other known compositions with enhanced functional activity, such as Catalina, representing a 40% emulgirujushchie concentrate oktilovom (C7-C9ethers of 2,4-D and dicamba in the ratio of 7: 1 (Catalan. Avenue PUP "Khimprom", NITY, Ufa, 1998; Davydov, A. M. Retrospective improve domestic herbicides for grain and tilled crops. Ufa, 1998, s. ) or octogen, 40% mulgirigala concentrate comprising 39.5% of 2,4-D in the form of ether and 0.5% chlorsulfuron (Davydov, 1998), i.e., not soluble in water derived herbicide acids. The solubility of the proposed structure greatly facilitates all procedures relating to the elaboration and application of the product, associated mainly with washing chemical reactors, machining tools and containers contaminated with residues of the herbicide. The extracted water rinse of the proposed structure can be fully utilized for its intended purpose. This quality, positive in the environmental sense, along with the above and other advantages make the use of the composition, intended for wide application in crops the main crops, of course, p is islote (2,4-D), 2-methoxy-3,6-dichlorobenzoyl acid (dicamba), surfactant and water, characterized in that it further comprises N-[4-methyl-6-methoxy-1,3,5-triazinyl-2)-aminocarbonyl] -2-chlorobenzenesulfonamide (chlorsulfuron), at a weight ratio of 2,4-D: dicamba: chlorsulfuron equal(12-18): 1: (0,046-0,23), N, N, N', N'-tetramethylmethylenediamine and n-dodecylamine in the following ratio, wt. %:

2,4-Dichlorophenoxyacetic acid - 12,0 - 42,0

2-Methoxy-3,6-dichlorobenzene acid - 1,0 - 3,5

N-[4-methyl-6-methoxy-1,3,5-triazinyl-2)aminocarbonyl] -2-chlorobenzenesulfonamide - 0,1 - 0,4

N, N, N', N'-tetramethylmethylenediamine - 8,0 - 26,3

Surfactant - 12,0 - 37,0

n-Dodecylamine 1,24 - 4,0

Water - The Rest
