The present invention also provides agrochemical compositions comprising at least one phenylether of formula (I) and auxiliaries customary for formulating crop protection agents.

The present invention also provides herbicidal compositions comprising at least one phenyleth- er of formula (I) (component A) and at least one further compound selected from the herbicidal compounds B (component B) and safeners C (component C).

The present invention also provides the use of phenylethers of formula (I) as herbicides, i.e. for controlling harmful plants.

The present invention furthermore provides a method for controlling unwanted vegetation where a herbicidal effective amount of at least one phenylethers of the formula (I) is allowed to act on plants, their seeds and/or their habitat. Application can be done before, during and/or after, preferably during and/or after, the emergence of the undesirable plants.

Moreover, the invention relates to processes and intermediates for preparing phenylethers of formula (I).

Further embodiments of the present invention are evident from the claims, the description and the examples. It is to be understood that the features mentioned above and still to be illustrated below of the subject matter of the invention can be applied not only in the combination given in each particular case but also in other combinations, without leaving the scope of the invention.

As used herein, the terms "controlling" and "combating" are synonyms.

As used herein, the terms "undesirable vegetation" and "harmful plants" are synonyms.

If the phenylethers of formula (I), the herbicidal compounds B and/or the safeners C as de- scribed herein are capable of forming geometrical isomers, for example E/Z isomers, it is possi- ble to use both, the pure isomers and mixtures thereof, in the compositions according to the invention. If the phenylethers of formula (I), the herbicidal compounds B and/or the safeners C as de- scribed herein have one or more centres of chirality and, as a consequence, are present as en- antiomers or diastereomers, it is possible to use both, the pure enantiomers and diastereomers and their mixtures, in the compositions according to the invention.

If the phenylethers of formula (I), the herbicidal compounds B and/or the safeners C as de- scribed herein have ionizable functional groups, they can also be employed in the form of their agriculturally acceptable salts. Suitable are, in general, the salts of those cations and the acid addition salts of those acids whose cations and anions, respectively, have no adverse effect on the activity of the active compounds.

Preferred cations are the ions of the alkali metals, preferably of lithium, sodium and potassium, of the alkaline earth metals, preferably of calcium and magnesium, and of the transition metals, preferably of manganese, copper, zinc and iron, further ammonium and substituted ammonium in which one to four hydrogen atoms are replaced by Ci-C 4 -alkyl, hydroxy-Ci-C 4 -alkyl, Ci-C 4 - alkoxy-Ci-C 4 -alkyl, hydroxy-Ci-C 4 -alkoxy-Ci-C 4 -alkyl, phenyl or benzyl, preferably ammonium, methylammonium, isopropylammonium, dimethylammonium, diethylammonium, diisoprop- ylammonium, trimethylammonium, triethylammonium, tris(isopropyl)ammonium, heptylammoni- um, dodecylammonium, tetradecylammonium, tetramethylammonium, tetraethylammonium, tetrabutylammonium, 2-hydroxyethylammonium (olamine salt), 2-(2-hydroxyeth-1-oxy)eth-1- ylammonium (diglycolamine salt), di(2-hydroxyeth-1-yl)ammonium (diolamine salt), tris(2- hydroxyethyl)ammonium (trolamine salt), tris(2-hydroxypropyl)ammonium, benzyltrime- thylammonium, benzyltriethylammonium, N,N,N-trimethylethanolammonium (choline salt), fur- thermore phosphonium ions, sulfonium ions, preferably tri(Ci-C 4 -alkyl)sulfonium, such as trime- thylsulfonium, and sulfoxonium ions, preferably tri(Ci-C 4 -alkyl)sulfoxonium, and finally the salts of polybasic amines such as N,N-bis-(3-aminopropyl)methylamine and diethylenetriamine.

Anions of useful acid addition salts are primarily chloride, bromide, fluoride, iodide, hydrogensul- fate, methylsulfate, sulfate, dihydrogenphosphate, hydrogenphosphate, nitrate, bicarbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate and also the anions of Ci-C 4 - alkanoic acids, preferably formate, acetate, propionate and butyrate.

Phenylethers of formula (I), herbicidal compounds B and/or safeners C as described herein hav- ing a carboxyl group can be employed in the form of the acid, in the form of an agriculturally suitable salt as mentioned above or else in the form of an agriculturally acceptable derivative, for example as amides, such as mono- and di-Ci-C 6 -alkylamides or arylamides, as esters, for example as allyl esters, propargyl esters, Ci-Cio-alkyl esters, alkoxyalkyl esters, tefuryl ((tetra- hydrofuran-2-yl)methyl) esters and also as thioesters, for example as Ci-Cio-alkylthio esters. Preferred mono- and di-Ci-C 6 -alkylamides are the methyl and the dimethylamides. Preferred arylamides are, for example, the anilides and the 2-chloroanilides. Preferred alkyl esters are, for example, the methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, mexyl (1 -methylhexyl), mep- tyl (1 -methylheptyl), heptyl, octyl or isooctyl (2-ethylhexyl) esters. Preferred Ci-C 4 -alkoxy-Ci-C 4 - alkyl esters are the straight-chain or branched Ci-C 4 -alkoxy ethyl esters, for example the 2- methoxyethyl, 2-ethoxyethyl, 2-butoxyethyl (butotyl), 2-butoxypropyl or 3-butoxypropyl ester. An example of a straight-chain or branched Ci-Cio-alkylthio ester is the ethylthio ester.

The organic moieties mentioned in the definition of the variables R 3 to R 37 and R a to R e are - like the term halogen - collective terms for individual enumerations of the individual group members. The term halogen denotes in each case fluorine, chlorine, bromine or iodine. All hydrocarbon chains, e.g. all alkyl, alkenyl, alkynyl, alkoxy chains, can be straight-chain or branched, the pre- fix C n -C m denoting in each case the possible number of carbon atoms in the group.

The invention also relates to agrochemical compositions comprising at least an auxiliary and at least one phenylether of formula (I) according to the invention.

An agrochemical composition comprises a pesticidally effective amount of an phenylether of formula (I). The term "effective amount" denotes an amount of the composition or of the corn- pounds I, which is sufficient for controlling unwanted plants, especially for controlling unwanted plants in crops (i.e. cultivated plants) and which does not result in a substantial damage to the treated plants. Such an amount can vary in a broad range and is dependent on various factors, such as the plants to be controlled, the treated crop or material, the climatic conditions and the specific phenylether of formula (I) used.

The phenylethers of formula (I), their N-oxides, salts or derivatives can be converted into cus- tomary types of agrochemical compositions, e. g. solutions, emulsions, suspensions, dusts, powders, pastes, granules, pressings, capsules, and mixtures thereof. Examples for agrochem- ical composition types are suspensions (e.g. SC, OD, FS), emulsifiable concentrates (e.g. EC), emulsions (e.g. EW, EO, ES, ME), capsules (e.g. CS, ZC), pastes, pastilles, wettable powders or dusts (e.g. WP, SP, WS, DP, DS), pressings (e.g. BR, TB, DT), granules (e.g. WG, SG, GR, FG, GG, MG), insecticidal articles (e.g. LN), as well as gel formulations for the treatment of plant propagation materials such as seeds (e.g. GF).

Application can be carried out before or during sowing.

Methods for applying phenylethers of formula (I), agrochemical compositions and /or herbicidal compositions thereof, on to plant propagation material, especially seeds, include dressing, coat- ing, pelleting, dusting, soaking and in-furrow application methods of the propagation material. Preferably, phenylethers of formula (I), agrochemical compositions and /or herbicidal composi- tions thereof thereof, respectively, are applied on to the plant propagation material by a method such that germination is not induced, e. g. by seed dressing, pelleting, coating and dusting.

Various types of oils, wetters, adjuvants, fertilizer, or micronutrients, and further pesticides (e.g. herbicides, insecticides, fungicides, growth regulators, safeners) may be added to the phe- nylethers of formula (I), the agrochemical compositions and/or the herbicidal compositions corn- prising them as premix or, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the agrochemical compositions according to the invention in a weight ratio of 1 :100 to 100:1 , preferably 1 :10 to 10:1.

The user applies the phenylethers of formula (I) according to the invention, the agrochemical compositions and/or the herbicidal compositions comprising them usually from a pre-dosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. Usually, the agrochemical composition is made up with water, buffer, and/or further auxiliaries to the desired application concentration and the ready-to-use spray liquor or the agrochemical composition according to the invention is thus obtained. Usually, 20 to 2000 liters, preferably 50 to 400 liters, of the ready-to-use spray liquor are applied per hectare of agricultural useful area.

According to one embodiment, either individual components of the agrochemical composition according to the invention or partially premixed components, e. g. components comprising phe- nylethers of formula (I) and optionally active substances from the groups B and/or C), may be mixed by the user in a spray tank and further auxiliaries and additives may be added, if appro- priate.

In a further embodiment, individual components of the agrochemical composition according to the invention such as parts of a kit or parts of a binary or ternary mixture may be mixed by the user himself in a spray tank and further auxiliaries may be added, if appropriate.

In a further embodiment, either individual components of the agrochemical composition ac- cording to the invention or partially premixed components, e. g components comprising phe- nylethers of formula (I) and optionally active substances from the groups B and/or C), can be applied jointly (e.g. after tank mix) or consecutively.

The phenylethers of formula (I) are suitable as herbicides. They are suitable as such, as an appropriately formulated composition (agrochemical composition) or as an herbicidal composition in combination with at least one further compound selected from the herbicidal active compounds B (component B) and safeners C (component C).

The phenylethers of formula (I), or the agrochemical compositions and /or herbicidal compositions comprising the phenylethers of formula (I), control vegetation on non-crop areas very efficiently, especially at high rates of application. They act against broad-leaved weeds and grass weeds in crops such as wheat, rice, maize, soya and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application.

The phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compo- sitions comprising them, are applied to the plants mainly by spraying the leaves. Here, the ap- plication can be carried out using, for example, water as carrier by customary spraying tech- niques using spray liquor amounts of from about 100 to 1000 l/ha (for example from 300 to 400 l/ha). The phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compositions comprising them, may also be applied by the low-volume or the ultra-low-volume method, or in the form of microgranules.

Application of the phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compositions comprising them, can be done before, during and/or after, preferably during and/or after, the emergence of the undesirable plants.

The phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compo- sitions comprising them, can be applied pre-, post-emergence or pre-plant, or together with the seed of a crop plant. It is also possible to apply the phenylethers of formula (I), or the agro- chemical compositions and/or the herbicidal compositions comprising them, by applying seed, pretreated with the phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compositions comprising them, of a crop plant. If the active ingredients are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that as far as possible they do not come into contact with the leaves of the sensitive crop plants, while the active ingredients reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).

In a further embodiment, the phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compositions comprising them, can be applied by treating seed. The treatment of seeds comprises essentially all procedures familiar to the person skilled in the art (seed dressing, seed coating, seed dusting, seed soaking, seed film coating, seed multilayer coating, seed encrusting, seed dripping and seed pelleting) based on the phenylethers of formula (I), or the agrochemical compositions and/or the herbicidal compositions prepared therefrom. Here, the herbicidal compositions can be applied diluted or undiluted.

The term“seed” comprises seed of all types, such as, for example, corns, seeds, fruits, tubers, seedlings and similar forms. Here, preferably, the term seed describes corns and seeds. The seed used can be seed of the useful plants mentioned above, but also the seed of transgenic plants or plants obtained by customary breeding methods.

When employed in plant protection, the amounts of active substances applied, i.e. the phe- nylethers of formula (I), component B and, if appropriate, component C without formulation aux- iliaries, are, depending on the kind of effect desired, from 0.001 to 2 kg per ha, preferably from 0.005 to 2 kg per ha, more preferably from 0.05 to 1.5 kg per ha and in particular from 0.1 to 1 kg per ha.

In another embodiment of the invention, the application rate of the phenylethers of formula (I), component B and, if appropriate, component C, is from 0.001 to 3 kg/ha, preferably from 0.005 to 2.5 kg/ha and in particular from 0.01 to 2 kg/ha of active substance (a.s.).

In another preferred embodiment of the invention, the rates of application of the phenylethers of formula (I) according to the present invention (total amount of phenylethers of formula (I)) are from 0.1 g/ha to 3000 g/ha, preferably 1 g/ha to 1000 g/ha, depending on the control target, the season, the target plants and the growth stage.

In another preferred embodiment of the invention, the application rates of the phenylethers of formula (I) are in the range from 0.1 g/ha to 5000 g/ha and preferably in the range from 0.5 g/ha to 2500 g/ha or from 2.5 g/ha to 2000 g/ha. In another preferred embodiment of the invention, the application rate of the phenylethers of formula (I) is 0.1 to 1000 g/ha, preferably 0.5 to 750 g/ha, more preferably 2.5 to 500 g/ha.

The required application rates of herbicidal compounds B are generally in the range of from 0.0005 kg/ha to 2.5 kg/ha and preferably in the range of from 0.005 kg/ha to 2 kg/ha or

0.01 kg/ha to 1.5 kg/h of a.s.

The required application rates of safeners C are generally in the range of from 0.0005 kg/ha to 2.5 kg/ha and preferably in the range of from 0.005 kg/ha to 2 kg/ha or 0.01 kg/ha to 1.5 kg/h of a.s.

In treatment of plant propagation materials such as seeds, e. g. by dusting, coating or drenching seed, amounts of active substance of from 0.1 to 1000 g, preferably from 1 to 1000 g, more preferably from 1 to 100 g and most preferably from 5 to 100 g, per 100 kilogram of plant prop- agation material (preferably seeds) are generally required.

In another embodiment of the invention, to treat the seed, the amounts of active substances applied, i.e. the phenylethers of formula (I), component B and, if appropriate, component C are generally employed in amounts of from 0.001 to 10 kg per 100 kg of seed.

When used in the protection of materials or stored products, the amount of active substance applied depends on the kind of application area and on the desired effect. Amounts customarily applied in the protection of materials are 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active substance per cubic meter of treated material.

In case of herbicidal compositions according to the present invention it is immaterial whether the phenylethers of formula (I), and the further component B and/or the component C are formulat- ed and applied jointly or separately.

In the case of separate application it is of minor importance, in which order the application takes place. It is only necessary, that the phenylethers of formula (I), and the further component B and/or the component C are applied in a time frame that allows simultaneous action of the ac- tive ingredients on the plants, preferably within a time-frame of at most 14 days, in particular at most 7 days.

The phenylethers of formula (I) according to the invention, or the agrochemical compositions and /or herbicidal compositions comprising them, can also be used in genetically modified plants. The term“genetically modified plants” is to be understood as plants whose genetic mate- rial has been modified by the use of recombinant DNA techniques to include an inserted se- quence of DNA that is not native to that plant species’ genome or to exhibit a deletion of DNA that was native to that species’ genome, wherein the modification(s) cannot readily be obtained by cross breeding, mutagenesis or natural recombination alone. Often, a particular genetically modified plant will be one that has obtained its genetic modification(s) by inheritance through a natural breeding or propagation process from an ancestral plant whose genome was the one directly treated by use of a recombinant DNA technique. Typically, one or more genes have been integrated into the genetic material of a genetically modified plant in order to improve cer- tain properties of the plant. Such genetic modifications also include but are not limited to target- ed post-translational modification of protein(s), oligo- or polypeptides e. g., by inclusion therein of amino acid mutation(s) that permit, decrease, or promote glycosylation or polymer additions such as prenylation, acetylation farnesylation, or PEG moiety attachment.

Plants that have been modified by breeding, mutagenesis or genetic engineering, e.g. have been rendered tolerant to applications of specific classes of herbicides, such as auxin herbi- cides such as dicamba or 2,4-D; bleacher herbicides such as hydroxyphenylpyruvate dioxygen- ase (HPPD) inhibitors or phytoene desaturase (PDS) inhibitors; acetolactate synthase (ALS) inhibitors such as sulfonyl ureas or imidazolinones; enolpyruvyl shikimate 3-phosphate synthase (EPSP) inhibitors such as glyphosate; glutamine synthetase (GS) inhibitors such as glufosinate; protoporphyrinogen-IX oxidase inhibitors; lipid biosynthesis inhibitors such as acetyl CoA car- boxylase (ACCase) inhibitors; or oxynil (i. e. bromoxynil or ioxynil) herbicides as a result of con- ventional methods of breeding or genetic engineering; furthermore, plants have been made re- sistant to multiple classes of herbicides through multiple genetic modifications, such as re- sistance to both glyphosate and glufosinate or to both glyphosate and a herbicide from another class such as ALS inhibitors, HPPD inhibitors, auxin herbicides, or ACCase inhibitors. These herbicide resistance technologies are, for example, described in Pest Management Science 61 , 2005, 246; 61 , 2005, 258; 61 , 2005, 277; 61 , 2005, 269; 61 , 2005, 286; 64, 2008, 326; 64,

2008, 332; Weed Science 57, 2009, 108; Australian Journal of Agricultural Research 58, 2007, 708; Science 316, 2007, 1185; and references quoted therein. Several cultivated plants have been rendered tolerant to herbicides by mutagenesis and conventional methods of breeding, e. g., Clearfield® summer rape (Canola, BASF SE, Germany) being tolerant to imidazolinones, e. g., imazamox, or ExpressSun® sunflowers (DuPont, USA) being tolerant to sulfonyl ureas, e. g., tribenuron. Genetic engineering methods have been used to render cultivated plants such as soybean, cotton, corn, beets and rape, tolerant to herbicides such as glyphosate, imidazoli- nones and glufosinate, some of which are under development or commercially available under the brands or trade names RoundupReady® (glyphosate tolerant, Monsanto, USA), Cul- tivance® (imidazolinone tolerant, BASF SE, Germany) and LibertyLink® (glufosinate tolerant, Bayer CropScience, Germany).

Furthermore, plants are also covered that are by the use of recombinant DNA techniques capa- ble to synthesize one or more insecticidal proteins, especially those known from the bacterial genus Bacillus, particularly from Bacillus thuringiensis, such as delta-endotoxins, e. g., CrylA(b), CrylA(c), CrylF, CrylF(a2), CryllA(b), CrylllA, CrylllB(bl) or Cry9c; vegetative insecticidal pro- teins (VIP), e. g., VIP1 , VIP2, VIP3 or VIP3A; insecticidal proteins of bacteria colonizing nema- todes, e. g., Photorhabdus spp. or Xenorhabdus spp.; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins, or other insect-specific neurotoxins; toxins pro- duced by fungi, such as Streptomycetes toxins, plant lectins, such as pea or barley lectins; ag- glutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cys- tatin or papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxy-steroid oxidase, ec- dysteroid-IDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors or HMG-CoA- reductase; ion channel blockers, such as blockers of sodium or calcium channels; juvenile hor- mone esterase; diuretic hormone receptors (helicokinin receptors); stilbene synthase, bibenzyl synthase, chitinases or glucanases. In the context of the present invention these insecticidal proteins or toxins are to be understood expressly also as including pre-toxins, hybrid proteins, truncated or otherwise modified proteins. Hybrid proteins are characterized by a new combina- tion of protein domains, (see, e. g., WO 02/015701 ). Further examples of such toxins or genet- ically modified plants capable of synthesizing such toxins are disclosed, e. g., in EP-A 374 753, WO 93/007278, WO 95/34656, EP-A 427 529, EP-A 451 878, WO 03/18810 und WO 03/52073. The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e. g., in the publications mentioned above. These insecti- cidal proteins contained in the genetically modified plants impart to the plants producing these proteins tolerance to harmful pests from all taxonomic groups of arthropods, especially to bee- ties (Coeloptera), two-winged insects (Diptera), and moths (Lepidoptera) and to nematodes (Nematoda). Genetically modified plants capable to synthesize one or more insecticidal proteins are, e. g., described in the publications mentioned above, and some of which are commercially available such as YieldGard® (corn cultivars producing the CrylAb toxin), YieldGard® Plus (corn cultivars producing CrylAb and Cry3Bb1 toxins), Starlink® (corn cultivars producing the Cry9c toxin), Herculex® RW (corn cultivars producing Cry34Ab1 , Cry35Ab1 and the enzyme Phosphinothricin-N-Acetyltransferase [PAT]); NuCOTN® 33B (cotton cultivars producing the CrylAc toxin), Bollgard® I (cotton cultivars producing the CrylAc toxin), Bollgard® II (cotton cultivars producing CrylAc and Cry2Ab2 toxins); VIPCOT® (cotton cultivars producing a VI P- toxin); NewLeaf® (potato cultivars producing the Cry3A toxin); Bt-Xtra®, NatureGard®, Knock- Out®, BiteGard®, Protecta®, Bt1 1 (e. g., Agrisure® CB) and Bt176 from Syngenta Seeds SAS, France, (corn cultivars producing the CrylAb toxin and PAT enzyme), MIR604 from Syngenta Seeds SAS, France (corn cultivars producing a modified version of the Cry3A toxin, c.f. WO 03/018810), MON 863 from Monsanto Europe S.A., Belgium (corn cultivars producing the Cry3Bb1 toxin), IPC 531 from Monsanto Europe S.A., Belgium (cotton cultivars producing a modified version of the CrylAc toxin) and 1507 from Pioneer Overseas Corporation, Belgium (corn cultivars producing the Cry1 F toxin and PAT enzyme).

Furthermore, plants are also covered that are by the use of recombinant DNA techniques capa- ble to synthesize one or more proteins to increase the resistance or tolerance of those plants to bacterial, viral or fungal pathogens. Examples of such proteins are the so-called“pathogenesis- related proteins” (PR proteins, see, e.g., EP-A 392 225), plant disease resistance genes (e. g., potato culti-vars, which express resistance genes acting against Phytophthora infestans derived from the Mexican wild potato, Solanum bulbocastanum) or T4-lyso-zym (e.g., potato cultivars capable of synthesizing these proteins with increased resistance against bacteria such as Er- winia amylovora). The methods for producing such genetically modi-fied plants are generally known to the person skilled in the art and are described, e.g., in the publications mentioned above.

Furthermore, plants are also covered that are by the use of recombinant DNA techniques capa- ble to synthesize one or more proteins to increase the productivity (e.g., bio-mass production, grain yield, starch content, oil content or protein content), tolerance to drought, salinity or other growth-limiting environmental factors or tolerance to pests and fungal, bacterial or viral patho- gens of those plants. Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of ingredients or new ingredients, specifically to improve human or animal nu- trition, e. g., oil crops that produce health-promoting long-chain omega-3 fatty acids or unsatu- rated omega-9 fatty acids (e. g., Nexera® rape, Dow AgroSciences, Canada).

Furthermore, plants are also covered that contain by the use of recombinant DNA techniques a modified amount of ingredients or new ingredients, specifically to improve raw material produc- tion, e.g., potatoes that produce increased amounts of amylopectin (e.g. Amflora® potato, BASF SE, Germany).

Furthermore, it has been found that the phenylethers of formula (I) according to the invention, or the agrochemical compositions and /or herbicidal compositions comprising them, are also suitable for the defoliation and/or desiccation of plant parts, for which crop plants such as cotton, potato, oilseed rape, sunflower, soybean or field beans, in particular cotton, are suitable. In this regard, agrochemical compositions and /or herbicidal compositions for the desiccation and/or defoliation of plants, processes for preparing these agrochemical compositions and /or herbicidal compositions and methods for desiccating and/or defoliating plants using the phenylethers of formula (I) have been found.

As desiccants, the phenylethers of formula (I) are particularly suitable for desiccating the above- ground parts of crop plants such as potato, oilseed rape, sunflower and soybean, but also cereals. This makes possible the fully mechanical harvesting of these important crop plants.

Also of economic interest is to facilitate harvesting, which is made possible by concentrating within a certain period of time the dehiscence, or reduction of adhesion to the tree, in citrus fruit, olives and other species and varieties of pernicious fruit, stone fruit and nuts. The same mechanism, i.e. the promotion of the development of abscission tissue between fruit part or leaf part and shoot part of the plants is also essential for the controlled defoliation of useful plants, in particular cotton.

Moreover, a shortening of the time interval in which the individual cotton plants mature leads to an increased fiber quality after harvesting.

Moreover, it has been found, that the phenylethers of formula (I), or the agrochemical compositions and /or herbicidal compositions comprising the phenylethers of formula (I), very efficiently also control PPO resistant weeds.

Accordingly, the present invention also provides a method for controlling the growth of PPO resistant weeds, which comprises contacting such weeds, parts of it, its propagation material or its habitat with phenylethers of formula (I), wherein the PPO resistant weeds are weeds, that are resistant to PPO-inhibiting herbicides except the phenylethers of formula (I).

The invention particularly relates to a method for controlling PPO resistant weeds in crops which comprises applying phenylethers of formula (I) to crops, where said PPO herbicide resistant weeds occur or might occur.

As used herein, the terms“PPO inhibitor”,“PPO inhibitor herbicide”,“PPO-inhibiting herbicide”, “protoporphyrinogen IX oxidase inhibitor herbicide”,“protoporphyrinogen IX oxidase-inhibiting herbicide”,“protoporphyrinogen oxidase inhibitor herbicide” and“protoporphyrinogen oxidase- inhibiting herbicide” are synonyms and refer to a herbicide that inhibits the enzyme protoporphy- rinogen oxidase of a plant.

As used herein, the terms“PPO inhibitor herbicide resistant weed”,“PPO-inhibiting herbicide resistant weed”,“PPO inhibitor resistant weed",“PPO resistant weed”,“protoporphyrinogen IX oxidase inhibitor herbicide resistant weed”,“protoporphyrinogen IX oxidase inhibiting herbicide resistant weed”,“protoporphyrinogen oxidase inhibitor herbicide resistant weed” , and“proto- porphyrinogen oxidase inhibiting herbicide resistant weed” are synonyms and refer to a plant that, in relation to a treatment with an appropriate or over-appropriate rate of PPO-inhibiting herbicide application, has inherited, developed or acquired an ability

(1 ) to survive that treatment, if it is one that is lethal to (i.e. eradicates) the wild type weed; or

(2) to exhibit significant vegetative growth or thrive after that treatment, if it is one that sup- presses groth of the wild-type weed.

Effective weed control is defined as at least 70% weed suppresison or eradication from the crop, or as at least 70% weed plant phototixicty, as determined 2 weeks after treatment.

Thus, PPO resistant weeds are weeds, which are not controlled by the application of PPO inhib- itors except the phenylethers of formula (I), whereas the respective sensitive biotype is con- trolled at that use rate.

Here,“not controlled” means that in a visual rating the weed control (herbicidal effect) is < 70 % of weed suppression or eradication as determined 2 weeks after treatment; and“controlled” means that in a visual rating the weed control is > 90 % of weed suppression or eradication as determined 2 weeks after treatment.

Preferably, PPO resistant weeds are weeds, which are not controlled (i.e. in a visual rating the weed control is < 70 % of weed suppression or eradication as determined 2 weeks after treat- ment) by the application of PPO-inhibiting herbicides except the phenylethers of formula (I).

Also preferably PPO-resistant weeds are those classified as being“PPO resistant” and thus listed according to Anonymous: List of herbicide resistant weeds by herbicide mode of action - weeds resistant to PPO-inhibitors (URL: http://www.weedscience.org/summary/MOA.aspx ). Particularly preferred the PPO resistant weeds are selected from the group consisting of Aca- lypha ssp., Amaranthus ssp., Ambrosia ssp., Avena ssp., Conyza ssp., Descurainia ssp., Eu- phorbia ssp. and Senecio ssp.;

especially preferred Amaranthus ssp., Ambrosia ssp. and Euphorbia ssp.;

more preferred Amaranthus ssp. and Ambrosia ssp..

Also particularly preferred the PPO resistant weeds are selected from the group consisting of Asian copperleaf {Acaiypha australis), smooth pigweed {Amaranthus hybridus), Palmer ama- ranth {Amaranthus Patmeri), redroot pigweed {Amaranthus retroftexus), tall/common waterhemp {Amaranthus tuberculatus, Amaranthus rudis, or Amaranthus tamariscinus), common ragweed {Ambrosia artemisiifolia), wild oat {Avena fatua), fleabane (Conyza ambigua), marestail {Conyza Canadensis), flixweed {Descurainia Sophia), wild poinsettia {Euphorbia heterophyiia) and east- ern groundsel {Senecio vernaiis);

especially preferred smooth pigweed {Amaranthus hybridus), Palmer amaranth {Amaranthus Paimeri), redroot pigweed {Amaranthus retrofiexus), tall/common waterhemp {Amaranthus tu berculatus or Amaranthus rudis), common ragweed {Ambrosia artemisiifolia) and wild poinsettia {Euphorbia heterophyiia},

more preferred tall/common waterhemp {Amaranthus tuberculatus, Amaranthus rudis or Ama ranthus tamariscinus) and common ragweed {Ambrosia artemisiifolia).

Most PPO resistant weeds, in particular the biotypes of Amaranthus tuberculatus, are resistant due to a codon deletion on the nuclear-encoded gene PPX2L that codes for the PPO enzyme which is dual-targeted to the mitochondria and the chloroplasts. This results in a loss of the glycine amino acid in position 210 (see e.g. B. G. Young et al, Characterization of PPO-lnhibitor-Resistant Wa- terhemp (Amaranthus tuberculatus) Response to Soil-Applied PPO-lnhibiting Herbicides, Weed Science 2015, 63, 511-521 ).

A second type of mutation, in particular in a resistant biotype of Ambrosia artemisiifolia, was identified as a mutation that expressed a R98L change of the PPX2 enzyme (S. L. Rousonelos, R. M. Lee, M. S. Moreira, M. J. VanGessel, P. J. Tranel, Characterization of a Common Ragweed (Ambrosia arte- misiifolia) Population Resistant to ALS- and PPO-lnhibiting Herbicides, Weed Science 60, 2012, 335- 344.).

Accordingly, preferably PPO-resistant weeds are weeds whose Protox enzyme is resistant to the application of PPO inhibitors due to a mutation that is expressed as a AG210 or R98L change of said Protox enzyme or equivalents to the PPX2L or PPX2 respectively, in particular that is ex- pressed as a AG210 or R98L change of said Protox enzyme. The preparation of the phenyluracils of formula (I) is illustrated by examples; however, the subject matter of the present invention is not limited to the examples given.

The herbicidal activity of the phenylethers of formula (I) was demonstrated by the following greenhouse experiments:

The culture containers used were plastic flowerpots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.

For the pre-emergence treatment, the active ingredients, which had been suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants, unless this had been impaired by the active ingredients.

For the post-emergence treatment, the test plants were first grown to a height of 3 to 15 cm, depending on the plant habit, and only then treated with the active ingredients which had been suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment.

Depending on the species, the plants were kept at 10 - 25°C or 20 - 35°C, respectively. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

Evaluation was carried out using a scale from 0 to 100. 100 means no emergence of the plants, or complete destruction of at least the aerial moieties, and 0 means no damage, or normal course of growth. A good herbicidal activity is given at values of at least 70 and a very good herbicidal activity is given at values of at least 85.

The plants used in the greenhouse experiments were of the following species:

At an application rate of 16 g/ha, the compounds (examples) 1 , 2, 4, 7, 8, 10, 11 , 12, 15, 16, 17, 18 and 19 applied by the post-emergence method, showed very good herbicidal activity against AMARE, CHEAL, ECHCG and SETVI.

At an application rate of 16 g/ha, the compound (example) 9 applied by the post-emergence method, showed very good herbicidal activity against AMARE, CHEAL and ECHCG.

At an application rate of 31 g/ha, the compound (example) 13 applied by the post-emergence method, showed very good herbicidal activity against AMARE, CHEAL and ECHCG.
