Often mixtures are mixtures of the binary type, but sometimes they can be three - or four-with one or more other compatible pesticides.

The proposed remedies as herbicides in kukuruzovic are intended for simultaneous, separate or extended time in the application for herbicide treatment of unwanted plants, in particular against weeds present in corn fields.

While applying you can apply the preparations ready for use, containing the above mixture of active principles. You can also use the drugs prepared immediately before use by preparation before application of the mixture of active substances.

The drug may also be applied by treating the protected crops sequentially one, and then other applicable compounds of the formula (I) and (II) to form on the plant of the proposed drug.

Offered drugs are mostly used in the form of herbicide compositions containing one or more carriers that are acceptable in agriculture, and/or one or more surface-active substances.

the positions. On the contrary, in the case of a mixture, ready for use, it may itself be in the form of a composition.

These compositions are applied as a herbicide substances, in addition to the active substance or mixture (depending on whether it is about preparation before application, or a mixture of ready-to-use), contain solid or liquid media, which is acceptable in agriculture, and surfactants, are also acceptable in agriculture gaseitsiwe. In particular, the applicable inert conventional carriers and conventional surfactants.

These compositions can also contain any other components, for example protective colloids, adhesives, thickeners, thixotropic substances, substances that promotes penetration, stabilizers, complexing agents and so on, In General terms, the active substances or their mixture used in the invention can be combined with all the solid or liquid additives in accordance with the methods of blending.

In General terms the proposed formulations usually contain from 0.05 to 95% (approximately, by weight) of the active substance or sinergicheskoe mixture of the invention.

The term "carrier" denotes an organic or mineral is to the plant. This carrier is a solid (clays, natural or synthetic silicates, silica, natural resins, waxes, solid fertilizers, and so on) or liquid (solvent).

Surfactant can be an emulsifier, dispersant or wetting agent of ionic or non-ionic type or a mixture of such surfactants. You can, for example, to call salt phenolsulfonic or naphthalenesulfonic, polycondensate ethylene oxide with alcohols, acids or fatty amines, or with substituted phenols (in particular ALKYLPHENOLS or kilfenora), salts of esters sulfonating acids, derivatives of taurine (in particular, alliterate), complex phosphate esters of alcohols or of polyoxyethylene, esters of fatty acids or polyhydric alcohols, derived from the function of sulfates, sulfonates and phosphates of the preceding compounds.

For preparations, ready-to-use, possible for the application form is mostly sustantially or concentrated suspension, preferably in the organic phase (European patent EP-A-313317), or wettable powder depending on the application. If bromoxynil presented in the form of ester, etc the ATA bromoxynil, for example, Bactria 20 (200 g/l), Bactria 21 (225 g/l) (Pesticide manual, 8th edition), in concentrated suspensions in organic or aqueous phase of 2-[[(4,6-dimethoxypyrimidine-2-yl] aminocarbonyl] (aminos-lpanel)-N,N - dimethyl-3-pyridinecarboxamide (European patent EP-A-237292, S. 46, example 14).
