The problem is solved offered by means of different effective content herbicide mixture comprising a derivative of 2,6-disubstituted pyridine of General formula (I)

where R1- once substituted by halogen phenyl radical,

R2- once replaced by halogenation with 1-3 carbon atoms, peroxyradical,

and a compound from the group of herbicides containing N-isopropyl-N-(4-forfinal)-amide (5-trifluoromethyl-1,3,4-thiadiazole-2-yl-oxy)-acetic acid (flufenacet), 2-(2-methoxycarbonyl-vinylsulfonylacetamido)-4-methyl-5-BC-propoxy-2,4-dihydro-3H-1,2,4-triazole-3-one (propoxycarbazone) and sodium salt of this compound (propoxycarbazone-sodium)at a weight ratio of the derivative of pyridine to the connection of the specified group of herbicides equal to 1:0.5 to 15.

The proposed tool preferably contains a derivative of 2,6-disubstituted pyridine of General formula (I), where

R1means substituted once by fluorine, phenyl radical,

R2means peroxyradical, replaced by halogenation with 1-3 carbon atoms.

In particular, the proposed product contains N-(4-forfinal)-6-[3-(tri-forfinal)phenoxy]-2-pyridinecarboxamide (picolinafen) as a derivative of 2,6-disubstituted pyridine.

According to the another preferred characteristic of the invention offer a means contains picolinafen and N-isopropyl-N-(4-forfinal)-amide(5-trifluoromethyl-1,3,4-thiadiazole-2-yl-oxy)acetic acid (flufenacet) or 2-(methoxycarbonyl-phenyl-sulfonylmethane)-4-methyl-5-n-propoxy-2,4-dihydro-3H-1,2,4-triazole-3-one (propoxycarbazone) or its sodium salt (propoxycarbazone-sodium).

However, the application of the proposed herbicide mixtures is not limited to these breeds, but also applies to other plants.

According to the invention it is possible to treat all plants and plant parts. In this case, the plant should be understood all plants and plant populations such as desired and undesired wild plants or crop plants (including wild plants). Cultivated plants can be plants grown using traditional methods under the Oia or optimization or biotechnological methods and techniques of genetic engineering or a combination of these methods, including the transgenic plants and including protected under the legislation on protection of plant varieties or unprotected plants.

Under parts of plants should understand all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower, root, and you can call, for example, leaves, needles, stems, flowers, fruit bodies, fruits and seeds and also roots, vegetative and generative seed material, for example cuttings, tubers, rhizomes, cuttings and seeds.

Treatment of plants and plant parts with the active compounds according to the invention is carried out by applying the active agent directly on plants or parts of plants or their environment, habitat or in the warehouse, that is, the location of their storage, when this treatment is carried out by conventional methods such as, for example, dipping, spraying, evaporating, dusting, scattering, smearing, and, in addition, when the material reproduction, in particular seed material, by applying one - or multi-layer coating.

The proposed herbicide tool is well tolerated by cultivated plants.

Herbicide tool can be translated in the usual formulation, for example solutions, emulsions, spray powders, suspensions, powders, opisyvaemye tools, pastes, soluble powders, granules, conc is you in the form of suspensions and emulsions, impregnated with active substances of natural and synthetic substances, as well as nonconception in polymeric substances form.

These drugs get in a known manner, for example by mixing the active substances with extenders, i.e. liquid solvents and/or solid carriers, optionally with the use of surface-active agents, i.e. emulsifiers and/or dispersants and/or foam.

In the case of using water as a filler can also be used as an aid in organic solvents. As liquid solvents are mainly used aromatic hydrocarbons, such as xylene, toluene, or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzene, ethylene chloride 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 also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, highly polar solvents such as dimethylformamide and dimethylsulfoxide, and water.

As solid carriers used:

for example, ammonium salt and a grinding of natural horn the x rocks such as, for example, kaolin, alumina, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and the grinding of synthetic rocks, such as highly dispersed silicic acid, alumina and silicates. As solid carriers for granules are used, for example, crushed and fractionated natural rocks such as calcite, marble, pumice, thick, dolomite, and also synthetic granules of inorganic and organic grinding, and also granules of organic material such as sawdust, coconut husk, corn cobs and stalks of tobacco. As emulsifying and/or foam-forming means are used, for example, nonionic and anionic emulsifiers, such as esters of polyoxyethylene and fatty acids, ethers of polyoxyethylene and fatty alcohols, for example alkylarylsulphonates simple ether, alkyl sulphonates, alkyl sulphates, arylsulfonate, as well as protein hydrolysates. As a dispersant is used, for example, ligninolytic liquor and methylcellulose.

The compositions can also be used binders, for example carboxymethylcellulose, natural and synthetic powdered, granular or latex polymers, such as gum Arabic, polyvinyl alcohol, polyvinyl acetate, and also natural phospholipids, such as feline and lecithins, and synthetic phospholipids. Other additives can be mineral and vegetable oils.

Can also be used colorants, such as inorganic pigments, for example iron oxide, titanium oxide, ferrocyanide blue, and organic dyestuffs, such as alizarin, azo and phthalocyanine dyes, metals, and trace elements in the form of salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

In the compositions the concentration of the active substances is usually from 0.1 to 95 wt.%, preferably from 0.5 to 90 wt.%.

The proposed herbicide tool usually used in the form of ready-made forms. However, it is also possible to mix in the tank of the active substance in the form of individual products before use.

Herbicide product can be applied as such or in the form of drugs in a mixture with known herbicide means. This can be applied to ready-made products or products obtained by mixing in the tank before use tools. Also can be used as drugs in a mixture with known active substances, such as fungicides, insecticides, acaricides, nematicides, means for protection from birds, substances to accelerate growth, nutrients, plants and tools to improve the soil structure. In addition, for certain a the th application particularly in post-harvest processing, it may be advantageous to add to the preparations as additional additives portable plants, mineral or vegetable oils (for example, trading product "Oleo DuPont 11E") or ammonium salts, such as ammonium sulphate or ammonium thiocyanate.

Herbicide product can be applied as such or in the form of drugs or cooked out of them by further dilution of the working forms, such as, for example, ready-to-use solutions, suspensions, emulsions, powders, pastes and granulates. The application in the normal way, for example by watering, spraying, spreading, spraying or scattering.

Herbicide tool according to the invention can be applied before or after germination of the plants, i.e. by pre-emergence treatment or post-harvest processing. They can also be incorporated into the soil before sowing.

In the case of herbicide means a synergistic effect is present when herbicide herbicide activity of the mixture exceeds the activity individually applied active compounds.

The expected activity of a mixture of two herbicides can be calculated as follows (see COLBY S.R.: "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, p.20-22, 1967):

If X = % damage by herbicide And at p kg/ha

and Y = % damage by herbicide B at q to the/ha

and E = the expected damage by herbicides a and B when p and q kg/ha

then E=X+Y-(X*Y/100).

If the actual damage is more designed, the mixture in relation to the activity Smeraldina, i.e. it exhibits a synergistic effect.

The following examples explain the invention.

Use the standard investigational drugs active substances. Propoxycarbazone-sodium used in the form of a 70%aqueous granulate, flufenacet - in the form of a 60%aqueous granulate and picolinafen - in the form of a 75%aqueous granulate. Active began to prepare the liquid for spraying, containing 0.1% additives RENEX-36.

Example

Post-harvest handling/greenhouse

Specified in tables a-1 - A-9 plants grown in the greenhouse under constant control conditions (temperature and light). Plant height from 5 to 15 cm are sprayed with a solution of the active substances. Thus concentration of liquid for spraying is chosen so that every desired amount of the active substance is applied in the form of a mixture with 500 l of water/ha

After spraying, the plants are left to stand in a greenhouse at constant conditions in relation to light and temperature.

Approximately 3 weeks after treatment to determine the degree of destruction of plants in % in comparison with untreated control plants.

This means:

0 % - no is oragene (corresponding untreated control plants),

100% - total destruction/defeat.

Experiments in open ground / cereal

Post-harvest handling in the spring

To study the possible synergies determine the effect of compounds picolinafen and propoxycarbazone-sodium on economically important weeds in cereals in the open ground. Experiments are performed on small plots of land, prepared with regard to agricultural practices. Thus choose the square with a pretty good development of weeds.

The use of active substances is carried out in the spring of post-harvest way throughout the area by spraying the drug an average droplet size. To obtain a suitable preparation of the active substance is prepared in the form of a 70%aqueous granules (70%by weight dispersible in water powder) or 75%aqueous granulate (75%dispersible in water powder and suspended in water. Then the solution for spraying used in conjunction with commonly used in practice, the amount of water.

Approximately 8-10 weeks after applying the solution for spraying visually determine herbicide action. This means:

0 % - no herbicide action,

100% complete eradication of weeds.

In this experiment, the proposed tool shows clearly expressed the military synergies in the fight against various weeds. The action is much higher than the value expected for a mixture of two active substances from the equation Colby.
