In addition, the herbicidal mixtures and the herbicidal porducts according to the invention can also be used in crops "which by culture or genetic engineering methods have become tolerant to the action of herbicides.

The herbicidal mixtures and the herbicidal products according to the invention can be applied before or after emergence. When the active substances are less tolerated by the crop plants, then application methods can be used in which "the herbicidal products are sprayed with the aid of spraying apparatus in such a way" that they do not fall on the leaves of the plants. sensitive crops, but «that only on the leaves of unwanted plants that grow below the first ones or on the ground covered with unwanted plants (post-directed, lay-by).

The herbicidal mixtures and the herbicidal products according to the invention can be used, for example, in the form of aqueous solutions, powders directly sprayable suspensions, also in the form of suspensions, dispersions or emulsions aqueous, oleic or otherwise, dispersions of oil, pastes, spraying, dusting or granulating agents, by means of spraying, spraying, sprinkling or sprinkling. The forms of application depend on the purpose of the use; In any case, they must guarantee the finest possible distribution of the active substances of the invention.

Inert additives are appropriate mineral fractions from medium boil to high boiling point, such as "kerosene or diesel oil, in addition, coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, such as paraffin, tetrahydronaphthaline, alkylated naphthalenes or their derivatives, alkylated benzenes or their derivatives, methanol, ethanol, propanol, butanol, cyclohexanol, cyclohexanone. or strongly polar solvents, such as N-methylpyrrolidone or water.

Aqueous application forms can be prepared from emulsion concentrates, pastes or wettable powders or granules dispersible in water by the addition of water. To obtain emulsions, pastes or oil dispersions, the substances can be homogenized as such or dissolved in an oil or solvent, by means of wetting agents, tackifiers, dispersants or emulsifiers, in water. However, a humectant, adherent, dispersant or emulsifier and, optionally, a solvent or oil, can also be prepared from the active substance, which can be diluted with water.

Suitable surfactants are alkali metal, alkaline earth metal, ammonium salts of lignin sulphonic acids, for example lignin sulphonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalene sulphonic acid, as well as fatty acids, alkyl and alkylaryl sulphonates, sulfates of lauryl ether and fatty alcohol, as well as the salts of sulphonated hexa, hepta and octadecanols, as well as glycol ethers of fatty alcohol, the condensates of sulfonated naphthalene and their derivatives with formaldehyde, the condensates of naphthalene or of naphthalic acids -sulfinsulphonates with phenol and formaldehyde, polyoxyethylenectyl-phenol ethers, isooctylphenol, octylphenol or nonylphenol ethoxylated, alkylphenol polyglycol ethers, tributylphenylpolyolol ethers, alkylaryl polyol alcohols, iso-tridecyl alcohol, fatty alcohol condensates eti-wood, ethoxylated castor oil, polyoxyethylene alkyl ethers, pol ioxypropylene, acetal polyglycol ether lauryl alcohol, sorbitol esters, sulphite residual liquors and methylcellulose.

The spraying, spraying and atomizing agents can be obtained by mixing the active substances together with a solid support.

Granules, eg coated granules, impregnates and homogeneous granules can be prepared by bonding the active substances with solid supports. Appropriate solid supports are mineral earth, such as silica gel, silicic acids, silicic gels, talc, kaolin, limestone, lime, chalk, bolus, loess, clay, dolomite, diatomaceous earth, calcium and magnesium sulfate, magnesium oxide, ground plastics, fertilizers, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and plant products, such as stone powders, tree bark powders, wood and nut shell powders, cellulose powders or other solid supports.

The formulations generally contain 0.01 to 95% by weight, preferably 0.5 to 90% by weight of the herbicidal mixture.

Furthermore, it may be useful to apply the mixtures or the herbicidal products according to the invention mixed with other plant protection products, for example with a product for controlling pests or fungi or bacteria. It is also interesting the miscibi-lidad with solutions of mineral salts, "which are used to ali-viar nutritive deficiencies or in microelements. You can also add oils and non-phytotoxic oil concentrates.

The amounts of application in pure herbicide mixture, namely without the formulation aids, amount, depending on the object to be combated, of the season, of the plants to be combated and their growth status, at 0.01 to 5 kg / has, preferably 0.03 to 4 kg / ha, especially 0.1 to 3.0 kg / ha of active substance (sa).

The herbicide products are applied to the plants mainly by spray, leaf ation. The application can be carried out in this case using water as support, using the usual techniques and spray quantities of approx. 100 up to 1000 1 / ha. It is also possible to use the products in the procedures called "Low Volume" and "Ultra-low-Volume" as well as the application of so-called granules.

Application examples The herbicidal mixtures are applied after the emergence (treatment of the leaves), using the sulfonylurea derivatives as 10 to 75% granules and the herbicidal compounds in the formulation, in which it is present as a commercial product.

These are trials in the open field in small plots in a sandy loam (pH 6.2 to 7.0) or sandy clay (pH 5.0 to 6.7) as a substrate.

Weeds have different heights and states of growth, on average they have a height of 5 to 20 cm, depending on their form of growth.

The herbicidal products are used alone or together, in the latter case partly as tank mixes, partly as ready formulations. The application is carried out in water (350 1 / ha) as distribution medium, in which «the active substances are emulsified, dissolved or suspended. The herbicide products are applied with the help of a parcel sprayer.

The trial period lasts 3 to 8 weeks, but cultures are also observed after this period.

The damage caused by the herbicide products is evaluated according to a graduated scale of 0% up to 100%, compared to untreated control plots, meaning 0 no damage and 100 the total destruction of the plants.

In the following examples the action of the herbicidal products to be used according to the invention is demonstrated, without it being possible to exclude the possibility of other types of applications with them.

In these tests, it is calculated according to the method of S.R. Colby (1967): Calculating synergistic and antagonistic responses of herbicid combinations, Weeds 15, pgs. 20 and next the E value to be expected in an additive effet of the individual active substances.

The calculation is made based on the following formula XY E = X + Y 100 where X = means the effect in percent achieved with preparation A with an application amount at Y = means the effect in percent achieved with preparation B with an application amount b E = means the effect to be expected (in%) when A + B is used in the application quantities a + b.

When the observed value is greater than the value E calculated according to Colby, then there is a synergetic action.

The herbidic products have a higher herbicidal effect than the value to be expected according to Colby from the observed effects of the individual components when they are used alone.
