- This allows the field of application of conventional crop protection products to be widened quite considerably and to be extended to, for example, crops such as wheat, barley, maize, rice and other crops in which a use of the herbicides was hitherto impossible, or only limited, that is to say at low rates and with a restricted spectrum.
- the herbicidally active substances and the abovementioned safeners can be applied together (as a readymix or by the tank mix method) or in succession in any desired sequence.
- the weight ratio of safener: herbicidally active substance may vary within wide limits and is preferably within the range from 1:100 to 100:1, in particular from 1:10 to 10:1.
- the optimum amounts of herbicidally active substance and safener in each case depend on the type of the herbicidally active substance used or on the safener used and on the species of the crop stand to be treated and can be determined in each individual case by simple, routine preliminary experiments.
- the main fields of application for the combinations according to the invention are, in particular, maize and cereal crops (for example wheat, rye, barley, oats), rice, sorghum, but also cotton and soybeans, preferably cereals, rice and maize.

- the herbicide/safener combination according to the invention may also be employed for controlling harmful plants in crops of genetically engineered plants which are either known or still to be developed.
- the transgenic plants are distinguished by particular, advantageous properties, for example by resistances to certain crop protection agents, resistances to plant diseases or pathogens causing plant diseases such as particular insects or microorganisms such as fungi, bacteria or viruses.
- Other particular properties relate for example, to the harvested material in terms of quantity, quality, storing properties, composition and specific constituents.
- transgenic plants are known which have an increased starch content or an altered starch quality, or those where the harvested material has a different fatty acid composition.
- effects on harmful plants to be observed in other crops are frequently accompanied by effects which are specific for application in the transgenic crop in question, for example an altered or specifically widened weed spectrum which can be controlled, altered application rates which may be used, preferably good compatibility with the herbicides to which the transgenic crop is resistant, and altered growth and yield of the transgenic crop plants.
- the invention therefore also relates to the use of the combination according to the invention for controlling harmful plants in transgenic crop plants.
- the safeners of the formulae (III)-(VI) and of group (b) and their combinations with one or more of the abovementioned herbicidally active substances of the formula (II) can be formulated in various ways, depending on the biological and/or chemico-physical parameters specified.

Olphen, “Introduction to Clay Colloid Chemistry”, 2 nd Ed., J. Wiley & Sons, N.Y.; C. Marsden, “Solvents Guide”, 2 nd Ed., Interscience, N.Y. 1963; McCutcheon's “Detergents and Emulsifiers Annual”, MC Publ.
- Wettable powders are preparations which are uniformly dispersible in water and which, besides the active substance, also comprise ionic and/or nonionic surfactants (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, polyoxyethylated fatty amines, fatty alcohol polyglycol ether sulfates, alkanesulfonates, alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutyinaphthalene-sulfonate, or else sodium oleoylmethyltaurinate, in addition to a diluent or inert substance.
- the herbicidally active substances are ground finely, for example in customary apparatus such as hammer mills, blower mills and air-jet mills, and they
- Emulsifiable concentrates are prepared, for example, by dissolving the active substance in an organic solvent such as butanol, cyclohexanone, dimethylformamide, xylene, or else higher-boiling saturated or unsaturated aliphatic or aromatic, or mixtures of the organic solvents with the addition of one or more ionic and/or nonionic surfactants (emulsifiers).
- organic solvent such as butanol, cyclohexanone, dimethylformamide, xylene, or else higher-boiling saturated or unsaturated aliphatic or aromatic, or mixtures of the organic solvents with the addition of one or more ionic and/or nonionic surfactants (emulsifiers).

- Emulsions for example oil-in-water emulsions (EW)
- EW oil-in-water emulsions
- Granules can be prepared either by spraying the active substance onto adsorptive, granulated inert material or by applying active substance concentrates to the surface of carriers such as sand, kaolinites or granulated inert material with the aid of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils.
- Suitable active substances can also be granulated in the manner which is conventional for the preparation of fertilizer granules, if desired as a mixture with fertilizers.
- water-dispersible granules are prepared by the customary processes such as spray-drying, fluidized-bed granulation, disk granulation, mixing with high-speed mixers and extrusion without solid inert material.
- the agrochemical formulations comprise 0.1 to 99% by weight, in particular 0.1 to 95% by weight, of active substances of the formulae (II)-(VII) and/or (b) or of the herbicide/antidote mixture of active substances (I) and (II)-(VII) and/or (b) 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 active substance concentration is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the active substance concentration is approximately 1 to 80% by weight.
- Formulations in the form of dusts comprise approximately 1 to 20% by weight of active substance, sprayable solutions approximately 0.2 to 20% by weight of active substance.
- the active substance content depends partly on whether the active compound is in liquid or solid form. The active substance content of the water-dispersible granules is, as a rule, between 10 and 90% by weight.
- the abovementioned formulations of active substances may comprise, if appropriate, the adhesives, wetters, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents, solvents, fillers, carriers, colorants, antifoams, evaporation inhibitors and pH and viscosity regulators which are customary in each case.
- Components which can be used for the mixtures according to the invention in mixed formualtions or in a tank mix are, for example, known active substances as they are described, for example, in Weed Research 26, 441-445 (1986), or “The Pesticide Manual”, 10 th edition, The British Crop Protection Council, 1994, and in the literature cited therein.

- the formulations which are in commercially available form are, if desired, diluted in the customary manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules.
- Preparations in the form of dusts, soil granules, granules for broadcasting and sprayable solutions are usually not diluted any further with other inert substances prior to use.
- the necessary application rate of the herbicides of the formula (I) varies with the external conditions such as, inter alia, temperature, humidity, and the nature of the herbicide used. It may be varied within wide limits, for example between 0.001 and 10.0 kg/ha or more of herbicide, but it is preferably between 0.005 and 5 kg/ha.
- a dust is obtained by mixing 10 parts by weight of a compound of the formula (II)-(VII) and/or from amongst group B (b) or of an active substance mixture of a herbicidally active substance of the formula (I) and a safener of the formula (II)-(VII) and/or from amongst group (b) and 90 parts by weight of talc as inert substance and comminuting the mixture in a hammer mill.
- a wettable powder which is readily dispersible in water is obtained by mixing 25 parts by weight of a compound of the formula (II)-(VII) and/or from amongst group B(b) or of an active substance mixture of a herbicidally active substance of the formula (I) and a safener of the formula (II)-(VII) and/or from amongst group B(b), 64 parts by weight of kaolin-containing quartz as inert substance, 10 parts by weight of potassium lignosulfonate and 1 part by weight of sodium oleoylmethyltaurinate as wetter and dispersant, and grinding the mixture in a pinned-disk mill.
- a concentrate which is readily dispersible or suspensible in water is obtained by mixing 20 parts by weight of a compound of the formula (II)-(VII) and/or from amongst group B(b) or of an active substance mixture of a herbicidally active substance of the formula (I) and a safener of the formula (II)-(VII) and/or from amongst group B(b), 6 parts by weight of alkylphenol polyglycol ether (®Triton X 207), 3 parts by weight of isotridecanbl polyglycol ether (8 EO) and 71 parts by weight of paraffinic mineral oil (boiling range, for example, approx. 255 to above 277° C.) and grinding the mixture in a ball mill to a fineness of below 5 microns.
- An emulsifiable concentrate is obtained from 15 parts by weight of a compound of the formula (II)-(VII) and/or from amongst group B(b) or of an active substance mixture of a herbicidally active substance of the formula (I) and a safener of the formula (II)-(VII) and/or from amongst group B(b), 75 parts by weight of cyclohexanone as solvent and 10 parts by weight of oxethylated nonylphenol as emulsifier.
- Water-dispersible granules are also obtained by homogenizing and precomminuting, in a colloid mill,
- Seeds or rhizome pieces of monocotyledonous and dicotyledonous harmful plants and useful plants are placed in sandy loam in pots of 9 to 13 cm diameter and covered with soil.
- rice plants and harmful plants which are undesired in this crop of useful plant, are grown in a waterlogged soil.
- Various doses of the herbicides and safeners formulated as emulsifiable concentrates or dusts were applied to the surface of the soil cover in the form of aqueous dispersions or suspensions or emulsions at a rate of 300 to 800 l of water/ha (converted), or, in the case of the rice test, poured into the irrigation water.
- the pots are then kept in the greenhouse under optimal conditions to grow the plants on. 3-4 weeks after the treatment, the damage to useful plants and harmful plants is scored visually. The damage is expressed in percentages in comparison with untreated controls.
