Moreover, the present invention may further provide a method for selectively controlling weeds in a habitat containing useful (crop) plants and weeds, comprising the application to the habitat of a weed-controlling amount of a composition according to the present invention. By "control" is meant eradication, reduction or prevention of growth, or prevention or reduction of germination. It is noted that the compounds of the present invention show significantly improved selectivity compared to known structurally similar compounds. In general, the plants to be controlled are unwanted plants (weeds). By "habitat" is meant the area in which the plants are growing or will grow. Application may be made to the habitat before and / or after the emergence of the crop plants. Preferably, the compounds of the present invention are applied to the habitat after the emergence of the crop plants. Some crop plants may be inherently resistant to the herbicidal effect of the compounds of formula (I).
[0093] The application rates of the compounds of formula (I) can vary within wide limits and depend on the nature of the soil, the method of application (pre- or post-emergence; seed dressing; application in the sowing furrow; no-tillage application, etc.), the crop plant, the weeds to be controlled, the prevailing weather conditions, and other factors governed by the application method, application time and the target crop. The compounds of formula (I) according to the invention are generally applied in amounts of 10 to 2500 g / ha, in particular 25 to 1000 g / ha, in particular 25 to 250 g / ha.
[0094] Application is generally made by spraying the composition, typically with a tractor-mounted large area sprayer, although other methods such as dusting (if a powder), dripping or irrigation can also be used.
[0095] The term "useful plants" should also be understood to include useful plants that have been rendered resistant to herbicides such as bromoxynil or to a class of herbicides, such as, for example, 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, ALS inhibitors such as primisulfuron, prosulfuron and trifloxysulfuron, 5-enol-pyroyl-shikimate-3-phosphate-synthase (EPSPS) inhibitors, glutamine synthetase (GS) inhibitors or protoporphyrinogen-oxidase (PPO) inhibitors, by conventional breeding or genetic engineering methods. An example of a crop that has been rendered resistant to imidazolinones, such as imazamox, by conventional breeding methods (mutagenesis) is Clearfield® summer rapeseed (canola). Examples of crops that have been rendered resistant to herbicides or classes of herbicides by genetic engineering methods include glyphosate- and glufosinate-tolerant corn varieties commercially available under the trade names RoundupReady®, Herculex I®, and LibertyLink®.
[0096] The term "useful plants" should also be understood to include useful plants which have been transformed using recombinant DNA techniques so as to be capable of synthesizing one or more selectively acting toxins, such as those known from toxin-producing bacteria, especially those of the genus Bacillus.
[0097] Examples of such plants are YieldGard® (a corn variety expressing a CryIA(b) toxin); YieldGard Root Feeders® (a corn variety expressing a CryIIIB(b1) toxin); YieldGard Plus® (a corn variety expressing a CryIA(b) and a CryIIIB(b1) toxin); Starlink® (a corn variety expressing a Cry9(c) toxin); Herculex I® (a corn variety expressing a CryIF(a2) toxin and the enzyme phosphinothricin N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (a cotton variety expressing a CryIA(c) toxin); Bollgard I® (a cotton variety expressing a CryIA(c) toxin); Bollgard II® (a cotton variety expressing CryIA(c) and CryIIA(b) toxins); VIPCOT® (a cotton variety expressing VIP toxin); NewLeaf® (a potato variety expressing CryIIIA toxin); NatureGard® Agrisure® GT Advantage (GA21 glyphosate tolerance trait), Agrisure® CB Advantage (Bt11 corn borer (CB) trait), Agrisure® RW (corn root-feeding nematode trait) and Protecta®.
[0098] Plant crops or their seed material can be both herbicide tolerant and insect feeding tolerant ("stacked" transgenic events) at the same time. For example, seeds can be capable of expressing an insecticidal Cry3 protein while at the same time being glyphosate tolerant.
[0099] Crop plants should also be understood to include those obtainable by conventional methods of breeding or genetic engineering and which contain so-called output traits, such as improved storage stability, higher nutritional value, and improved flavor.

[0121] The mixing partners of the compounds of formula (I) may also be in the form of esters or salts, for example as described in The Pesticide Manual, Sixteenth Edition, British Crop Protection Council, 2012.
[0122] Mixtures can be used to advantage in the above mentioned formulations (in which case the "active ingredient" refers to the respective mixture of the compound of formula (I) with the mixing partner).
[0123] The compounds or mixtures of the present invention can also be used in combination with one or more herbicide safeners.Examples of such safeners include benoxacor, cloquintocet (including cloquintocet mexyl), cyprosulfamide, dichlormid, fenchlorazole (including fenchlorazole-ethyl), fenclorim, fluxofenim, furilazole, isoxadifen (including isoxadifen-ethyl), mefenpyr (including mefenpyr-diethyl), metcamifen and oxabetrinil.Particularly preferred is the mixture of the compound of formula I with cyprosulfamide, isoxadifen-ethyl, cloquintocet mexyl and / or metcamifen.
[0124] The safeners of the compounds of formula (I) can also be used as described, for example, in The Pesticide Manual, 16 th Edition (BCPC), 2012. Reference to cloquintocet-mexyl also applies to its lithium, sodium, potassium, calcium, magnesium, aluminum, iron, ammonium, quaternary ammonium, sulfonium or phosphonium salts, as disclosed in WO 02 / 34048.
[0125] Preferably, the mixing ratio of compound of formula (I) to safener is from 100:1 to 1:10, in particular from 20:1 to 1:1.
[0126] The compounds of formula (I) are usually used in the form of agrochemical compositions and can be applied to the crop area or plants to be treated simultaneously or sequentially with further compounds. These further compounds can be, for example, fertilizers or trace element donors or other preparations that affect plant growth. They can also be selective or non-selective herbicides, as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, optionally with further carriers, surfactants or application-promoting adjuvants that are customarily used in the art of formulations.
[0127] As used herein, the term "habitat" refers to the field in which the plant is growing or in which the seeds of the cultivated plant have been sown or in which the seeds will be sown in the soil. It includes the soil, the seeds and seedlings, as well as established vegetation.
[0128] The term "plant" refers to all physical parts of a plant, including seeds, seedlings, seedlings, roots, tubers, stems, stalks, foliage and fruits.
[0129] The term "plant propagation material" is understood to refer to reproductive parts of plants, such as seeds, which can be used for their propagation, as well as vegetative bodies, such as cuttings or tubers, for example potatoes. For example, seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes and plant parts may be mentioned. Also mentioned are sprouted plants and shoots that are to be transplanted after germination or emergence from the soil. These shoots may be protected by a complete or partial treatment by immersion before transplantation. Preferably, "plant propagation material" is understood to refer to seeds.
[0130] Pesticides referred to herein using common names are known, for example from “The Pesticide Manual”, 15th Ed., British Crop Protection Council 2009.
[0131] The compounds of formula (I) can be used in unmodified form or, preferably, together with the auxiliaries conventionally employed in the art of formulation.For this purpose, they can be conveniently formulated in a known manner into emulsifiable concentrates, coating pastes, direct-sprayable or dilutable solutions or suspensions, dilute emulsions, wettable powders, soluble powders, dusts, granules, and capsules, for example, in polymeric materials.The application method, such as spraying, misting, dusting, scattering, coating, or pouring, as well as the type of composition, is selected according to the intended purpose and the current situation.The composition can also contain further auxiliaries, such as stabilizers, defoamers, viscosity regulators, binders or adhesives, as well as fertilizers, sources of trace elements, or other formulations for obtaining special effects.
[0132] For example, suitable carriers and adjuvants for use in agriculture may be solid or liquid and are substances useful in formulation technology, such as natural or regenerated mineral substances, solvents, dispersants, wetting agents, adhesives, thickeners, binders or fertilizers. Such carriers are described, for example, in WO 97 / 33890.
[0133] The compounds of formula (I) are usually used in the form of compositions and can be applied to the crop area or plants to be treated simultaneously or sequentially with further compounds. These further compounds can be, for example, fertilizers or trace element donors or other preparations that affect plant growth. They can also be selective or non-selective herbicides, as well as insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired with further carriers, surfactants or application-promoting adjuvants customarily used in the art of formulations.
[0134] The compound of formula (I) may be the sole active ingredient in the composition or, where appropriate, may be mixed with one or more additional active ingredients, such as pesticides, fungicides, synergists, herbicides or plant growth regulators, which may in some cases result in unexpected synergistic activity.
[0135] Typically, the formulations contain 0.01-90% by weight of active agent, 0-20% of agriculturally acceptable surfactants and 10-99.99% of solid or liquid inert compounding agents and adjuvants, the active agent being composed of at least the compound of formula (I) together with components (B) and (C) and optionally other active agents, in particular fungicides or preservatives. Concentrated forms of the composition generally contain about 2-80%, preferably about 5-70% by weight of active agent. Application forms of the formulations may contain, for example, 0.01-20% by weight, preferably 0.01-5% by weight of active agent. Commercial products will preferably be formulated as concentrates, but end users will usually utilize diluted formulations.
