? GWIBINQCTQNFS OF HERBICIDES? E FENTLSULFONILUREQ AND PROTFptnPFS NENQRifl PESCRIPTIVR The invention relates to the technical area of crop protection agents, in particular combinations of active substance / antidote (= combinations of active substance / protectants) which are remarkably suitable for use in combating harmful plants competent in crops of useful plants. Some of the most recent herbicidal active substances have very good properties on use and can be used at very low application rates to combat a broad spectrum of grass and broadleaf weeds. However, many of the highly effective active substances are not fully compatible with (ie, not sufficiently effective in) some important crop plants such as corn, rice or cereals, so there are narrow limits on their use. Thus, in some crops they can not be used at all or can be used only at such low application rates that the desired broad activity of the herbicide on the harmful plants is not assured. Specifically, many herbicides of the formula (P), which is defined below, can not be used completely selectively to combat harmful plants in corn, rice, cereals or some other crops. Some of the recent experimental work of the present inventors has shown that crop plants such as corn, rice, wheat, barley and others can surprisingly be protected against undesirable damage by such herbicides when applied together with certain acting compounds. co or herbicide or protective antidotes.

This makes it possible to extend very widely the range of uses of conventional crop protection agents, and extend it, for example, to crops such as wheat, barley, maize and other grass crops in which the use of herbicides has hitherto been impossible or possible only to a limited degree, in other words, in low doses without a very broad action. The active herbicidal substances and the mentioned protectants can be applied together (as a ready-to-use formulation or in the tank mixing process) or in any desired sequence one after the other. The proportion by protective weight / active herbicidal substance can vary within wide limits and is preferably in the range from 1: 100 to 100: 1, in particular from 1:10 to 10: 1. The optimum amounts of active and protective herbicidal substance depend in each case on the type of active herbicidal substance used or the protector used and the type of crop to be treated, and can be determined by appropriate preliminary tests in each case. The main areas of use of the protectors are, in particular, corn and cereal crops (wheat, rye, barley, oats), rice, sorghum, but also cotton and soybeans, preferably cereals and corn. The protectors of the formulas (Bl) and (B2) can, depending on their properties, be used for the pretreatment of the seed of the crop plant (fertilizer of the seed) or to be introduced before sowing within the seed furrows or applied together with the herbicide before or after the emergence of the plants. The presurgery treatment includes both the treatment of the growing area before planting and the treatment of the growth areas that have been planted but that so far do not show any growth. The use together with the herbicide is preferred. Tank mixes or ready-to-use formulations can be used for this purpose. The protective application regimes required can vary within wide limits depending on the indication and herbicide active substance and are, as a rule, on the scale of 0.001 to 5 kg, preferably 0.005 to 0.5 kg, d active substance per hectare. Therefore, the present invention also relates to a method for protecting plants from the phytotoxic side effects of the herbicides of the formula (A), which consists of applying an effective amount of a compound of the formula (Bl) and / or (B2) before, after or at the same time as the herbicidal active substance of the formula (A) to the plants, plant seeds or the growth area. The compounds of the formulas (Bl) and (B2) and combinations thereof with one or more of said herbicidal substances can be formulated in a variety of ways, depending on the specified biological and / or physicochemical parameters. Examples of possible and suitable formulations are: wettable powders (UP), emulsifiable concentrates (EC), water soluble powders (SP), water soluble concentrates (SL), concentrated emulsions (BU) such as oil in water emulsions and of water in oil, solutions or spray emulsions, suspensions in capsule (CS), dispersions based on oil or water (SC), s? spoemulsions, suspension concentrates, dust powders (DP), solutions miscible in oil (OL), fertilizers for seeds, granules (GR) in the form of microgranules, sprays, absorption and adsorption, granules for application or distribution in the soil, water-soluble granules (SG), water-dispersible granules (UG), ULV formulations, microcapsules and waxes. These types of individual formulation are known in principle and are described, for example in: Uinnacker-Küchler, "Chernische Technologie" [Chemical Technology !, volume 7, C. Hauser Verlag, n? Nich, 4th edition, 1986; Uade van Valkernburg, "Pesticide Formulations", Marcel Dekker N.Y., 1973; K. Martens, "Spray Dryi g Handbook", 3rd ed. 1979, G. Goodwin Ltd., London. The requisite formulation auxiliaries, such as inert materials, surfactants, solvents and other additives are also known and are described, for example in: Uatkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd ed., Darland Books , Caldwell N.3., Hv Olphen, "Introduction to Clay Colloid Chemistry," 2nd ed., 3. Uiley 8c Sons, N.Y .; C. Marsden, "Solvents guide", 2nd ed., Interscience, N.Y., 1963; McCutcheon, "Detergents and Emulsifiers Annual", MC Publ.

Verlagsgesell. , Stuttgart 1976; Uinnacker-Küchler, "Chemischß Technologie" [Chemical Technology3, volume 7, C. Hauser Verlag, Munich, 4th edition, .1.986; It is also possible on the basis of these formulations to produce combinations with other substances with pesticidal activity, such as, for example, insecticides, acaricides, herbicides, fungicides and with protectants, fertilizers and / or growth regulators, for example in the form of a formulation or tank mix ready to use. The wettable powders are products that can be uniformly dispersed in water and which, in addition to the active substance and apart from a diluent or inert substance, also contain ionic and nonionic surfactants (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, polyoxyethylated fatty amines, fatty alcohol polyglycol ether sulphates, alkane sulphonates, alkylbenzene sulphonates, sodium ligninsulfonate, sodium 2,2'-dinaphthylmethane-6,6'-disulfonate, sodium dibutylnaphthalene sulfonate or any sodium salt of Oleoylmethytaurine. The wettable powders are produced by finely grinding the herbicidal active substances, for example in common apparatuses such as hammer mills, integral fan mills and air jet mill and mixed, simultaneously or subsequently with the formulation auxiliaries. Emulsifiable concentrates are produced by dissolving the active substance in an organic solvent, for example butanol, cyclohexanone, dimethyl ormamide, xylan or any higher boiling aromatic compound or hydrocarbons or mixtures of organic solvents with the addition of one or more surfactants. ionic and / or non-ionic (emulsifiers). Examples of emulsifiers that may be used are: calcium alkylarylsulfonates such as Ca dodecylbenzenesulfonate or non-ionic emulsifiers such as polyglycol fatty acid ethers, polyglycolyl alkylaryl ethers, fatty alcohol polyglycol ethers, propylene oxide / oxide condensation products of ethylene, alkyl polyethers, sorbitan esters such as, for example, sorbitan fatty acid esters or polyoxyethylene sorbitan esters such as, for example, polyoxyethylene sorbitan fatty acid esters. Dustable powders are obtained by grinding the active substance with finely divided solid substances, for example talc, natural clays such as caoline, bentonite and pyrophyllite, or diatomaceous earth. Suspension concentrates can be based on water or oil. They can be produced, for example, by wet milling using commercially available bead mills and, where appropriate, by adding surfactants such as those already listed above, for example, for the other types of formulation. Emulsions, for example, oil-in-water (EU) emulsions may be produced, for example, by means of stirrers, colloid mills and / or static mixers using aqueous organic solvents and, where appropriate, surfactants such as those already mentioned. have previously enlisted, for example, for the other types of formulation. The granules can be produced either by spraying the active substance on granulated inert builder material or by applying concentrates of active substance by means of adhesives, for example polyvinyl alcohol, sodium polyacrylate or any mineral oil, on the surface of vehicles such as sand, kaolinites or granulated inert material. It is also possible that the appropriate active substances are granulated in the common form to produce fertilizer granules - if required mixed with fertilizers. Water-dienable granules are, as a rule, produced by common procedures such as spray drying, fluid bed granulation, plate granulation, mixing with high speed mixers and extrusion without solid inert material. In the production of plate granules, fluidized bed, extruder and aspersion, see, for example, the procedures in "Spray-Drying Handbook", 3rd ed., 1979, G. Goodwin Ltd., London; J: E: Browning, "Agglo eration", Chemical and Engineering 1967, pgs. 147 ßt seq .; "Perry's Chemical Engineer's Handbook," 5th ed., HcGraw-Hill, New York, 1973, pgs. 8-57. For further details of the formulation for crop protection agents, see, for example, G.C. Klingman, "Ueed Control as a Science", 3ohn Uiley and Sons, Inc., New York, 1961, p. 81-96 and ZJ.D. Freyer, S.A. Evans, "Ueed Control Handbook," 5th. ed. , Blackwll Scientific Publications, Oxford, 1968, p. 101-103. The agrochemical compositions contain, as a rule, 0.1 to 99% by weight, in particular 0.1 to 95% by weight of active substances of the formula (Bl) and / or (B2) or of the mixture (A) of active substance of herbicide / antidote and (Bl) and / or (B2) and 1 to 99.9% by weight, in particular 5 to 99.8% by weight of a solid or liquid additive and 0 to 25% by weight, in particular 0.1 to 25% by weight of a surfactant. The concentration of active substance in wettable powders is, for example, about 10 to 90% by weight, and the remainder of up to 100% by weight consists of common formulation ingredients. The concentration of active substance in emulsifiable concentrates is from about 1 to 80% by weight. Formulations in the form of powder contain from about 1 to 20% by weight of active substances, and the spray solutions contain from about 0.2 to 20% by weight of active substances. In granules, such as water-dispersible granules, the content of active substance depends in part on whether the active compound is in liquid or solid form. As a rule, the content of dispersible granules in water is between 10 and 90% by weight. The aforementioned active substance formulations additionally contain, when appropriate, adhesives, wetting agents, dispersants, and uleifiers, penetration promoters, preservatives, frost protection agents and solvents, fillers, vehicles and dyes, anti-foam agents, evaporation inhibitors and agents that influence the pH and viscosity, which are common in each case. The examples of active substances which can be used as combination partners for the active substances according to the invention in mixture formulations or in a tank mixture are those described in, for example, Ueed Research 26, 441-445 (1986). , or "The Pesticide Manual", ninth edition, The British Crop Protection Council, 1990/91, Bracknell, England, and the literature cited therein.

BIOLOGICAL EXAMPLES EXAMPLE i Several crop plants are grown in plastic pots with a diameter of 9 cm in a greenhouse until the fixed stage and subsequently treated with the particular herbicide or with a mixture of the herbicide and the protector by the post-emergence method. This includes the herbicide of the formula (A) and the coclets of the formula (B) which are applied in the form of aqueous suspensions or emulsions with a rate of application of water which converts to 300 1 / ha. Four weeks after the treatment, the plants are visually evaluated for each type of damage by the applied herbicides, paying particular attention to the point of inhibition of persistent growth. This evaluation takes place in percentages (scale from 0 to 100%) compared to untreated controls. The results of the tests show that various protectors according to the invention make it possible to selectively use the herbicide in crops such as wheat, barley and corn without this having an adverse effect on the herbicidal activity.
