FORM 2 THE PATENTS ACT 1970 [39 OF 1970] COMPLETE SPECIFICATION [See Section 10] "SELECTIVE HERBICIDES BASED ON 2,6-DISUBSTITUTED PYRIDINE DERIVATIVES" BAYER AKTIENGESELLSCHAFT, A company of Germany., D-51368 Leverkusen, Germany GRANTED 30-8-2007 The following specification particularly describes and ascertain the nature of the invention and the manner in which it is to be performed :- Selective herbicides based on 2,6-disubstituted pyridine derivatives The invention relates to novel herbicidal synergistic active compound combinations comprising, on the one hand, known 2,6-disubstituted pyridine derivatives and, on the other hand, known herbicidally active compounds and/or safeners and which can be used particularly successfully for the selective control of weeds in various crops of useful plants. As herbicides with broad action, 2,6-disubstituted pyridine derivatives form part of the subject-matter of a number of patent applications (cf. EP-A 447 004, WO-A 94/22833). However, the known pyridine derivatives have a number of gaps in their activity. The compatibility of these compounds with crop plants is likewise not entirely satisfactory under all conditions. Surprisingly, it has now been found that a number of known active compounds from the group of the 2,6-disubstituted pyridine derivatives, used jointly with known herbicidally active compounds from different substance classes, show pronounced synergistic effects with respect to the activity against weeds, and that such broadly active compound preparations can be used particularly advantageously for the selective control of weeds in crops of useful plants, such as, for example, wheat. Surprisingly, it has also been found that the 2,6-disubstituted pyridine derivatives, on their own or together with known herbicidally active compounds, when used jointly with the crop-plant-compatibility-improving compounds (safeners/antidotes) described below, prevent damage to the crop plants particularly well and can be used particularly advantageously as a broadly active combination preparation for the selective control of weeds in crops of useful plants, for example cereal. The invention provides selective herbicidal compositions, characterized in that they comprise an effective amount of an active compound combination comprising (a) at least one 2,6-disubstituted pyridine derivative of the general formula (I) in which R1 represents a 5- or 6-membered heterocycle comprising 1 to 3 nitrogen atoms which is optionally mono- or polysubstituted by halogen and/or C1-C3-halogenoalkyl or represents a phenyl radical which is optionally mono- or polysubstituted by halogen and/or C1-C3-halogenoalkyl, R represents a phenoxy radical which is optionally substituted by halogen and/or C1-C3-halogenoalkyl, R represents a hydrogen atom or methyl, and W represents oxygen or the group -CO-NH-, ("active compounds of group 1") and b) one or more compounds of a second group of herbicides comprising the active compounds mentioned below: N-isopropyl-N-(4-fluorophenyl)-(5-trifluoromethyl-l,3,4-thiadiazol-2-yl-oxy)-acetamide (flufenacet, DE-38 21 600),

Le A 34 090-Foreiegn countries Surprisingly, it has now been found that the active compound combinations defined above of the 2,6-disubstituted pyridine derivatives of the formula (I) and the active compounds of group 2 listed above, optionally in combination with active compounds of groups 3 and 4, have particularly high herbicidal activity combined with very good compatibility with useful plants and can be used in various crops, in particular in wheat, but additionally also in rice, maize and barley for the selective control of weeds. Surprisingly, the herbicidal activity of the inventive active compound combinations of compounds of the abovementioned groups 1 and 2 is considerably higher than the sum of the activities of the individual active compounds. This means that there is not only a complementary action but also an unforeseeable synergistic effect. The novel active compound combinations are tolerated well by a 15 large number of crops, and the novel active compound combinations also effectively control weeds which are otherwise difficult to control. The novel active compound combinations are therefore a valuable addition to the selective herbicides. Furthermore, it has surprisingly been found that the active compound combinations 2|0 defined above of 2,6-disubstituted pyridine derivatives of the formula (I) and a safener/antidote ("active compounds of group 3") in combination with one or more of the abovementioned active compounds of group 2 have particularly high herbicidal activity combined with very good compatibility with useful plants and can be used in various crops, in particular in cereals and maize, especially wheat, but also in soya, potatoes and rice, for the selective control of weeds. Moreover, it has surprisingly been found that the safener role described above can also be played by the herbicidally active substance 2,4-dichlorophenoxy-acetic acid (2,4-D) and its derivatives. The compounds diethyl l-(2,4-dichlorophenyl)-4,5-dihydro-5-methyl-lH-pyrazole-3,5- Le A 34 090-Foreign Countries dicarboxylate (mefenpyr-diethyl), 1-methylhexyl [(5-chloro-8-quinolinyl)oxy]acetate (cloquintocet-mexyl) and ethyl l-(2,4-dichlorophenyl)-5-(trichioromethyl)-lH-l,2,4- triazole-3-carboxylate (fenchlorazole-ethyl) are described in the following patent applications: DE-A-39 39 503, EP-A-191 736 and DE-A-35 25 205. 2,4-D is a known 5 herbicide. Furthermore, it is surprisng that, from a large number of known safeners or antidotes capable of antagonizing the damaging effect of a herbicide on the crop plants, it is specifically the active compounds of group 3 listed above which neutralize the 10 damaging effect of compounds of the formula (I), in combination with one or more of the abovementioned active compounds of group 2, on the crop plants virtually completely without adversely affecting the herbicidal activity against the weeds. The particularly advantageous effect of the particularly preferred combination 15" partners among the active compounds of group 3, in particular with respect to sparing cereal plants, such as, for example, rice, wheat, barley and rye, as crop plants, may be emphasized here. The active compound combinations according to the invention can be used, for 25 example, in connection with the following plants: Dicotyledonous weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, 2i Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus, Taraxacum. Dicotyledonous crops of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, 30 Lactuca, Cucumis, Cucurbita. Le A 34 090-Foreign Countries Monocotyledonous weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus, 5 Apera, Phalaris. Monocotyledonous crops of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus, Allium. 10 However, the use of the active compound combinations according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants. 15 2f According to the invention, it is possible to treat all plants and parts of plants. By plants are understood here all plants and plant populations, such as desired and undesirable wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including transgenic plants and including plant varieties which can or cannot be protected by varietal property rights. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes. Parts of plants also include harvested crops and vegetative and generative propagation material, for example seedlings, tubers, rhizomes, cuttings and seeds. 30 The treatment of the plants and parts of plants according to the invention with the active compounds is carried out directly or by action on their environment, habitat or storage area according to customary treatment methods, for example by dipping, spraying, evaporating, atomizing, broadcasting, brushing on and, in the case of Le A 34 090-Foreign Countries propagation material, in particular in the case of seeds, furthermore by one- or multi-layer coating. The synergistic effect of the active compound combinations according to the invention is particularly strongly pronounced at certain concentration ratios. However, the ratios by weight of the active compounds in the active compound combinations can be varied within relatively wide ranges. In general, from 0.01 to 1000 parts by weight, preferably from 0.05 to 500 parts by weight and particularly preferably from 0.1 to 100 parts by weight of active compound of group 2 are present per part by weight of active 10 compound of the formula (I). The advantageous effect of the crop plant compatibility of the active compound combinations according to the invention is likewise particularly strongly pronounced at certain concentration ratios. However, the ratios by weight of the active compounds in the active compound combinations can be varied within relatively wide ranges. In general, from 0.001 to 1000 parts by weight, preferably from 0.01 to 100 parts by weight and particularly preferably from 0.1 to 10 parts by weight of one of the compounds (antidotes/safeners) mentioned above under (c) which improve the crop plant tolerability are present per part by weight of active compound of the formula (I), 20 its salts or its mixtures with active compounds of group 2. The active compound combinations can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspo-emulsion concentrates, natural and synthetic 25 substances impregnated with active compound, and very fine encapsulations in polymeric substances. These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with 30 the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents. Le A 34 090-Foreign Countries If the extender used is water it is also possible to use, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydro- 5 carbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl 10 sulphoxide, as well as water. Suitable solid carriers are: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, 1 5 chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize 20 cobs and tobacco stalks; suitable emulsifying and/or foam-forming agents are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as protein hydrolysates; suitable dispersing agents are: for example lignin-sulphite waste liquors and 25 methylcellulose. Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latexes, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and 30 synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils. Le A 34 090-ForeignCountries It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc. The formulations in general comprise between 0.1 and 95 per cent by weight, preferably between 0.5 and 90%, of active compounds, including the safeners. In general, the active compound combinations according to the invention are applied in the form of ready mixes. However, the active compounds which the active compound combinations comprise can also be formulated individually and mixed upon use, i.e. applied in the form of tank mixes. 15 The novel active compound combinations can be used as such or in the form of their formulations, and furthermore also as mixtures with other known herbicides, ready mixes or tank mixes again being possible. They may also be mixed with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellents, growth substances, plant nutrients and agents which improve soil structure. For particular application purposes, in particular when applied post-emergence, it may furthermore be advantageous to incorporate, in the formulations, mineral or vegetable oils which are tolerated by plants (for example the commercial product "Oleo DuPont HE") or ammonium salts such as, for example, ammonium sulphate or ammonium thiocyanate, as further additives. 25! The novel active compound combinations can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomizing, dusting or 30 scattering. Le A 34 090-Foreign Countries The active compound combinations according to the invention can be applied before and after the plants have emerged, that is to say pre-emergence and post-emergence. They can also be incorporated into the soil before sowing. A synergistic effect in herbicides is always present when the herbicidal activity of the active compound combination exceeds the activity of the active compounds when applied individually. The expected activity for a given combination of two herbicides can be calculated as follows (cf. COLBY, S.R.: "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, pages 20 - 22, 1967): IfX = % damage by herbicide A (active compound of the formula I) at an application rate of p kg/ha andY = % damage by herbicide B (active compound of the formula II) at an application rate of q kg/ha and E = the expected damage of the herbicides A and B at application rates of p and q kg/ha, thenE = X +Y - (X * Y/100). If the actual damage exceeds the calculated value, then the activity of the combination is superadditive, i.e. a synergistic effect exists. Accordingly the present invention relates to a herbicidal composition comprising an effective amount of an active compound combination comprising (a) N-(4-fluorophenyl)-6-[3-(trifluoromethyl)phenoxy]-2- pyridincarboxamide (picolinafen), and (b) 2-(2- methoxycarbonylphenylsulphonylamino-carbonyl)-4-methyl-5-n-propoxy-2, 4-dihydro-3H-l,2,4-triazol-3-one or the sodium salt thereof (propoxycarbazone-sodium). Le A 34 090-Foreign countries Use Examples Customary formulations of the active compounds in question were used. Propoxycarbazone-sodium was used as 70 WG, flufenacet as 60 WG and picolinafen as 75 WG formulation. From the active compounds, an aqueous spray liquor containing 0.1% of the additive Renex-36 was prepared. Example A Post-emergence/greenhouse Test plants are grown in a greenhouse under controlled conditions (temperature and light conditions). When the plants have reached a height of 5 to 15 cm, they are sprayed with the test solution. The concentration of the spray liquor is chosen such that the particular amounts of active compound desired are applied in 500 1 of water/ha. After the spray treatment, the plant containers are stored in a greenhouse at constant light and temperature conditions. After about 3 weeks, the degree of damage to the crop plants is rated in % damage in comparison to the development of the untreated control. The figures denote: 0 % = no damage (like untreated control) 100 % = total destruction/damage Active compounds, application rates, test plants and results are shownin the tables below, where the abbreviations used in the tables have the following meaning: a.i. = active ingredient = active compound e A 34 090-foreign Countries Table A-l Application rate g of ai/ha Avenua observed Avenua calculated* flufenacet 60 30 10 10 picolinafen 30 8 20 0 flufenacet + picolinafen 60 + 30 30 + 30 60 + 8 70 70 70 28 28 10 * values calculated by the method of Colby Table A-2 Application rate g of ai/ha Digitaria observed Digitaria calculated* flufenacet 125 60 10 0 picolinafen 30 50 flufenacet + picolinafen 125 + 30 60 + 30 90 90 55 50 * values calculated by the method of Colby Le A 34 090-Foreign Countries -,30- Table A-3 Application rate g of ai/ha Echinochloa observed Echinochloa calculated* flufenacet 60 60 picolinafen 8 10 flufenacet + picolinafen 60 + 8 90 64 * values calculated by the method of Colby Table A-4 Application rate g of ai/ha Cassia observed Cassia calculated* flufenacet 125 0 picolinafen 30 40 flufenacet + picolinafen 125 + 30 100 40 * values calculated by the method of Colby Le A 34 090-Foreign countries Table A-5 Application rate g of ai/ha Ipomoea observed Ipomoea calculated* flufenacet 125 60 30 30 picolinafen 30 15 8 70 70 70 flufenacet + picolinafen 125 + 30 125 + 15 125 + 8 60 + 8 100 100 98 98 79 79 79 79 * values calculated by the method of Colby Table A-6 Application rate g of ai/ha Viola observed Viola calculated* flufenacet 60 0 picolinafen 8 90 flufenacet + picolinafen 60 + 8 100 90 * values calculated by the method of Colby 10 Le A 34 090-Foreign Countries Table A-7 Application rate g of ai/ha Avenua observed Avenua calculated* propoxycarbazone-sodium 60 30 15 60 50 50 picolinafen 30 15 20 10 propoxycarbazone- sodium + picolinafen 60 + 30 30 + 30 15 + 30 60+15 30+15 15+15 80 80 80 80 80 80 68 60 60 64 55 55 * values calculated by the method of Colby 5 Table A-8 Application rate g of ai/ha Loliutn observed Lolium calculated* propoxycarbazone-sodium 30 15 20 0 picolinafen 30 15 20 0 propoxycarbazone- sodium + picolinafen 30 + 30 30+15 15+15 50 50 30 36 20 0 * values calculated by the method of Colby Le A 34 090-Foreign countries Table A-9 Application rate Polygonum Polygonum g of ai/ha observed calculated* propoxycarbazone- 60 0 sodium 30 0 15 0 picolinafen 30 70 15 70 propoxycarbazone- 60+30 80 70 sodium 30+30 80 70 + 15+30 80 70 picolinafen 60+15 90 70 30+15 80 70 15+15 80 70 Le A 34 090-foreign Countries Example B Outdoor trials 5 Cereal Post-emergence spring To examine a possible synergism, the compounds picolinafen and propoxy- carbazone-sodium were tested under outdoor conditions in cereal against 10 economically important weed grasses. The small-plot experiments were conducted on areas used for agricultural cultivation. The selected areas had a high weed content. The active compounds were applied in spring by the post-emergence method and over the entire area, using spray application with a medium droplet size. To prepare 15 an advantageous preparation of active compound, the active compounds were formulated as 70 WG (70% w/w water-dispersible powder) or 75 WG (75% w/w water-dispersible powder) and suspended in water. The spray liquor was then applied in a water application rate customarily used in practice. 20 About 8-10 weeks after the application of the spray liquor, the herbicidal activity was scored visually. The figures denote: 0 % = no herbicidal effect, 100 % = total destruction of the crop or the weeds. 25 In this experiment, the active compound mixtures showed a highly pronounced synergism in the activity against various weeds. The activity exceeded the value, which was expected for the mixture according to Colby"s formula (COLBY 1967), considerably (see the tables below).
