The invention relates to a liquid herbicidal composition comprising a) glufosinate, or a salt thereof; b) an amine component selected from primary, secondary, tertiary amines, and ammonium salts thereof, and quaternary ammonium salts; wherein the molecular weight of the primary, secondary or tertiary amines, of the ammonium cation in the ammonium salts, or of the quaternary ammonium cation in the quaternary ammonium salts is from 32 to 200 g/mol; and c) a compound of formula (I)
[R-(A)x-OSO3−]-M+ (I);
wherein the variables have a meaning as defined herein below.
Further objects are a method for controlling undesirable vegetation, which method comprises applying the herbicidal composition to a locus where undesirable vegetation is present or is expected to be present; the use of the amine component for increasing the herbicidal activity of liquid herbicidal compositions comprising glufosinate, or a salt thereof, and a compound of formula (I); a method for increasing the herbicidal activity of liquid herbicidal compositions comprising glufosinate or a salt thereof, and a compound of formula (I) comprising the step of contacting the liquid herbicidal composition with the amine component; a method of producing the herbicidal composition comprising the step of contacting the amine component with the compound of formula (I) and glufosinate or a salt thereof in any given order; plant propagation material comprising the herbicidal composition; and to a method for treating plant propagation material comprising the step of treating plant propagation material with the herbicidal composition.
There is an ongoing need to find additives for agrochemical compositions that enhance the biological effectivity of the composition, increase its physical and/or chemical stability, or increase the loading of the agrochemical composition with active ingredients and/or adjuvants. Increased biological effectivity allows for lower application rates of the active ingredient, which reduces costs and health risks for the applicant. Higher loading of agrochemical compositions reduces the weight of a given packaging unit, thereby facilitating transportation and handling of the canisters containing the agrochemical compositions. However, agrochemical compositions with higher loading of agrochemical active ingredients and/or adjuvants suffer from stability problems, such as gelling, flocculation, and creaming. Also agrochemical compositions with higher loading often have a high viscosity, which negatively affects their handling by the applicant.
U.S. Pat. No. 10,091,994B2 discloses additives for agrochemical compositions. The additives are alkoxylated and sulfonated alcohols, which are present in the form of salts and wherein the cation may be sodium.
It was the objective of the present invention to provide herbicidal compositions of glufosinate or its salts that have an increased biological effect, in particular an increased herbicidal effect against undesired vegetation, have an enhanced physical and/or chemical stability, high loading with agrochemical active ingredients and/or adjuvants and at the same can be easily handled by the applicant.
It was surprisingly found that the amine component increases the biological activity of liquid herbicidal compositions comprising glufosinate. The improved biological activity relates both the increased herbicidal effect against unwanted vegetation, to a reduced damage of certain crop plants, and an enhanced defoliation effect. Further advantages are that the herbicidal compositions have a high loading with glufosinate, that they are physically stable upon storage.
Accordingly, the invention relates to a liquid herbicidal composition comprising
[R-(A)x-OSO3−]-M+ (I);

The molar ratio of protonated amine N+ to non-protonated amine N is typically up to 50:1, preferably up to 20:1, more preferably up to 15:1 most preferably up to 8:1.
The ratio is dependent of the pH of the liquid herbicidal composition. The pH is typically from 5 to 12, preferably from 6 to 10, more preferably from 6.5 to 9. The pH may be adjusted by the addition of an acid, such as HCl, H2SO4, H2SO3, or methylsulfonic acid. By addition of an acid, the amine N is protonated and present in the form of its ammonium salt, such as the chloride salt, the sulfate salt, the sulfonate salt, or the methyl sulfonate salt. Thus, the ammonium salt of the primary, secondary or tertiary amine is formed in situ by reaction of the acid with the amine N. Alternatively, the respective ammonium salt of the primary, secondary or tertiary amine may be added to the composition.
Since compounds of formula (I) are ionic compounds, and since the amine component may contain, or form an ammonium salt, or contain a quaternary ammonium salt, the compounds of formula (I) and the amine component may exchange their respective counterions in solution as displayed in Scheme 2

For example, glufosinate and its salts—such as glufosinate ammonium—and its herbicidal activity have been described e.g. by F. Schwerdtle et al. Z. Pflanzenkr. Pflanzenschutz, 1981, Sonderheft IX, pp. 431-440.

Glufosinate is a racemate of two enantiomers, out of which only one shows sufficient herbicidal activity (see e.g. U.S. Pat. No. 4,265,654 and JP92448/83). Even though various methods to prepare L-glufosinate (and respective salts) are known, the mixtures known in the art do not point at the stereochemistry, meaning that the racemate is present (e.g. WO 2003024221, WO2011104213, WO 2016113334, WO 2009141367).
In one embodiment, the herbicidal composition comprises racemic glufosinate mixtures as described above, wherein the glufosinate comprises about 50% by weight of the L-enantiomer and about 50% by weight of the D-enantiomer.

No. 70033-13-5) and glufosinate-P-potassium (IUPAC-Name: potassium (2S)-2-amino-4-(methylphosphinato)butyric acid) for L-glufosinate.
Hence, mixtures according to the herbicidal composition may contain (L)-glufosinate-ammonium or (L)-glufosinate-sodium or (L)-glufosinate-potassium as (L)-glufosinate salts and (L)-glufosinate as free acid, preferably (L)-glufosinate.

Exemplary formulation types of the herbicidal composition have been described in WO2007/092351A1 and WO2005/117583A2.
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 herbicidal composition comprising them as premix or, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the herbicidal 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 herbicidal composition according to the invention usually from a pre-dosage device, a knapsack sprayer, a spray tank, a spray plane, or an irrigation system. Usually, the herbicidal 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 herbicidal 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.

In a further embodiment, either individual components of the herbicidal composition according to the invention or partially premixed components, e. g. components comprising compounds of formula (I) and/or glufosinate or a salt thereof and/or the amine component may be mixed by the user in a spray tank and further auxiliaries and additives may be added, if appropriate.

The herbicidal compositions have a comparatively low dynamic viscosity and stay homogeneous even at high concentrations of compound of formula (I).
The dynamic viscosity as referred to herein can be measured by means of a Brookfield viscosimeter, i.e. a rotational viscosimeter with a cone-plate geometry. The dynamic viscosity may be determined according to industry standard EN ISO 2555:2018. Usually, the dynamic viscosity is measured at 25° C. In this method, the shear rate of the rotation viscosimeter is constantly increased and the shear stress is measured. For Newtonian Fluids, the measurement results in a linear dataset according to a direct proportionality between the shear stress and the shear rate. For non-Newtonian fluids, the measurement results in a non-linear dependency between shear stress and shear rate. The dynamic viscosity, also called apparent viscosity, is typically determined by measuring the slope of a line through the origin of the coordinate system and the shear stress as determined at a shear rate of 100/second. The true viscosity, which may be different from the apparent viscosity for non-Newtonian fluids, is determined by calculating the slope of the tangent of the experimental curve as measured at a shear rate of 100/second.

Here and below, the term “binary herbicidal composition” refers to herbicidal compositions comprising glufosinate or a salt thereof, preferably L-glufosinate or a salt thereof, such as the ammonium salt of glufosinate, and a herbicide B or a safener C.
In binary herbicidal compositions, the weight ratio of glufosinate or a salt thereof to active compound B is generally in the range of from 1:1000 to 1000:1, preferably in the range of from 1:500 to 500:1, in particular in the range of from 1:250 to 250:1 and particularly preferably in the range of from 1:75 to 75:1.
In binary compositions comprising glufosinate or a salt thereof and a safener C, the weight ratio of glufosinate or a salt thereof to the active compound C is generally in the range of from 1:1000 to 1000:1, preferably in the range of from 1:500 to 500:1, in particular in the range of from 1:250 to 250:1 and particularly preferably in the range of from 1:75 to 75:1.
The herbicidal compositions are suitable as herbicides. Accordingly, these herbicidal compositions control vegetation on non-crop areas very efficiently, especially at high rates of application. They act against broad-leafed weeds and grass weeds in crops such as wheat, rice, corn, soybeans and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application.
The herbicidal compositions according to the invention are applied to the plants mainly by spraying the leaves. Here, the application can be carried out using, for example, water as carrier by customary spraying techniques using spray liquor amounts of from about 100 to 1000 I/ha (for example from 300 to 400 I/ha). The herbicidal compositions may also be applied by the low-volume or the ultra-low-volume method, or in the form of microgranules.
Application of the herbicidal compositions according to the present invention can be done before, during and/or after, preferably during and/or after, the emergence of the undesirable plants.
The herbicidal compositions according to the present invention can be applied pre- or post-emergence or together with the seed of a crop plant. It is also possible to apply the herbicidal composition by applying seed, pretreated with a herbicidal composition of the invention, of a crop plant. If the active compounds 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 compounds reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).
In a further embodiment, the herbicidal composition according to the invention can be applied by treating seed. The treatment of seed 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 herbicidal compositions. 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.
Moreover, it may be advantageous to apply the herbicidal compositions of the present invention on their own or jointly in combination with other crop protection agents, for example with agents for controlling pests or phytopathogenic fungi or bacteria or with groups of active compounds which regulate growth. Also of interest is the miscibility with mineral salt solutions which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates can also be added.
When employed in plant protection, the amounts of glufosinate or salt thereof without formulation auxiliaries, 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 0.9 kg per ha and in particular from 0.1 to 0.75 kg per ha.
In treatment of plant propagation materials such as seeds, e. g. by dusting, coating or drenching seed, amounts of glufosinate or salt thereof is 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 propagation material (preferably seeds) are generally required.
When used in the protection of materials or stored products, the amount of glufosinate or salt thereof 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 agrochemical active ingredient per cubic meter of treated material.
In the methods of the present invention it is immaterial whether the glufosinate or salt thereof, the compound of formula (I), the amine component, and optionally the second agrochemical active ingredient are formulated 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 glufosinate or salt thereof, the compound of formula (I), the amine component, and optionally the second agrochemical active ingredient are applied in a time frame that allows simultaneous action of the active ingredients on the plants, preferably within a time-frame of at most 14 days, in particular at most 7 days.
Depending on the application method in question, the herbicidal compositions according to the invention can additionally be employed in a further number of crop plants for eliminating undesirable pests, such as invertebrate pests, fungi, or weeds, preferably weeds. Examples of suitable crops are the following:
Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Avena sativa, Beta vulgaris spec. altissima, Beta vulgaris spec. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Brassica oleracea, Brassica nigra, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot esculenta, Medicago sativa, Musa spec., Nicotiana tabacum (N. rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spec., Pistacia vera, Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Prunus armeniaca, Prunus cerasus, Prunus dulcis and prunus domestica, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Sinapis alba, Solanum tuberosum, Sorghum bicolor (S. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticale, Triticum durum, Vicia faba, Vitis vinifera, Zea mays.
The herbicidal compositions according to the invention can also be used in crops which have been modified by mutagenesis or genetic engineering in order to provide a new trait to a plant or to modify an already present trait, preferably a resistance against glufosinate or its salts.
The term “crops” as used herein includes also (crop) plants which have been modified by mutagenesis or genetic engineering in order to provide a new trait to a plant or to modify an already present trait.
Mutagenesis includes techniques of random mutagenesis using X-rays or mutagenic chemicals, but also techniques of targeted mutagenesis, in order to create mutations at a specific locus of a plant genome. Targeted mutagenesis techniques frequently use oligonucleotides or proteins like CRISPR/Cas, zinc-finger nucleases, TALENs or meganucleases to achieve the targeting effect.
Genetic engineering usually uses recombinant DNA techniques to create modifications in a plant genome which under natural circumstances cannot readily be obtained by cross breeding, mutagenesis or natural recombination. Typically, one or more genes are integrated into the genome of a plant in order to add a trait or improve a trait. These integrated genes are also referred to as transgenes in the art, while plant comprising such transgenes are referred to as transgenic plants. The process of plant transformation usually produces several transformation events, which differ in the genomic locus in which a transgene has been integrated. Plants comprising a specific transgene on a specific genomic locus are usually described as comprising a specific “event”, which is referred to by a specific event name. Traits which have been introduced in plants or have been modified include in particular herbicide tolerance, insect resistance, increased yield and tolerance to abiotic conditions, like drought.
Herbicide tolerance has been created by using mutagenesis as well as using genetic engineering. Plants which have been rendered tolerant to acetolactate synthase (ALS) inhibitor herbicides by conventional methods of mutagenesis and breeding comprise plant varieties commercially available under the name Clearfield®. However, most of the herbicide tolerance traits have been created via the use of transgenes.
Herbicide tolerance has been created to glyphosate, glufosinate, 2,4-D, dicamba, oxynil herbicides, like bromoxynil and ioxynil, sulfonylurea herbicides, ALS inhibitor herbicides and 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, like isoxaflutole and mesotrione.
Transgenes which have been used to provide herbicide tolerance traits comprise: for tolerance to glyphosate: cp4 epsps, epsps grg23ace5, mepsps, 2mepsps, gat4601, gat4621 and goxv247, for tolerance to glufosinate: pat and bar, for tolerance to 2,4-D: aad-1 and aad-12, for tolerance to dicamba: dmo, for tolerance to oxynil herbicies: bxn, for tolerance to sulfonylurea herbicides: zm-hra, csr1-2, gm-hra, S4-HrA, for tolerance to ALS inhibitor herbicides: csr1-2, for tolerance to HPPD inhibitor herbicides: hppdPF, W336 and avhppd-03.
Transgenic corn events comprising herbicide tolerance genes are for example, but not excluding others, DAS40278, MON801, MON802, MON809, MON810, MON832, MON87411, MON87419, MON87427, MON88017, MON89034, NK603, GA21, MZHG0JG, HCEM485, VCO-Ø1981-5, 676, 678, 680, 33121, 4114, 59122, 98140, Bt10, Bt176, CBH-351, DBT418, DLL25, MS3, MS6, MZIR098, T25, TC1507 and TC6275.
Transgenic soybean events comprising herbicide tolerance genes are for example, but not excluding others, GTS 40-3-2, MON87705, MON87708, MON87712, MON87769, MON89788, A2704-12, A2704-21, A5547-127, A5547-35, DP356043, DAS44406-6, DAS68416-4, DAS-81419-2, GU262, SYHTØH2, W62, W98, FG72 and CV127.

Insect resistance has mainly been created by transferring bacterial genes for insecticidal proteins to plants. Transgenes which have most frequently been used are toxin genes of Bacillus spec. and synthetic variants thereof, like cry1A, cry1Ab, cry1Ab-Ac, cry1Ac, cry1A.105, cry1F, cry1Fa2, cry2Ab2, cry2Ae, mcry3A, ecry3.1Ab, cry3Bb1, cry34Ab1, cry35Ab1, cry9C, vip3A(a), vip3Aa20. However, also genes of plant origin have been transferred to other plants. In particular genes coding for protease inhibitors, like CpTI and pinII. A further approach uses transgenes in order to produce double stranded RNA in plants to target and downregulate insect genes. An example for such a transgene is dvsnf7.
Transgenic corn events comprising genes for insecticidal proteins or double stranded RNA are for example, but not excluding others, Bt10, Bt11, Bt176, MON801, MON802, MON809, MON810, MON863, MON87411, MON88017, MON89034, 33121, 4114, 5307, 59122, TC1507, TC6275, CBH-351, MIR162, DBT418 and MZIR098.
Transgenic soybean events comprising genes for insecticidal proteins are for example, but not excluding others, MON87701, MON87751 and DAS-81419.
Transgenic cotton events comprising genes for insecticidal proteins are for example, but not excluding others, SGK321, MON531, MON757, MON1076, MON15985, 31707, 31803, 31807, 31808, 42317, BNLA-601, Event1, COT67B, COT102, T303-3, T304-40, GFM Cry1A, GK12, MLS 9124, 281-24-236, 3006-210-23, GHB119 and SGK321.
Increased yield has been created by increasing ear biomass using the transgene athb17, being present in corn event MON87403, or by enhancing photosynthesis using the transgene bbx32, being present in the soybean event MON87712.
Crops comprising a modified oil content have been created by using the transgenes: gm-fad2-1, Pj.D6D, Nc.Fad3, fad2-1A and fatb1-A. Soybean events comprising at least one of these genes are: 260-05, MON87705 and MON87769.
Tolerance to abiotic conditions, in particular to tolerance to drought, has been created by using the transgene cspB, comprised by the corn event MON87460 and by using the transgene Hahb-4, comprised by soybean event IND-00410-5.
Traits are frequently combined by combining genes in a transformation event or by combining different events during the breeding process. Preferred combination of traits are herbicide tolerance to different groups of herbicides, insect tolerance to different kind of insects, in particular tolerance to lepidopteran and coleopteran insects, herbicide tolerance with one or several types of insect resistance, herbicide tolerance with increased yield as well as a combination of herbicide tolerance and tolerance to abiotic conditions.
Plants comprising singular or stacked traits as well as the genes and events providing these traits are well known in the art. For example, detailed information as to the mutagenized or integrated genes and the respective events are available from websites of the organizations “International Service for the Acquisition of Agri-biotech Applications (ISAAA)” (http://www.isaaa.org/gmapprovaldatabase) and the “Center for Environmental Risk Assessment (CERA)” (http://cera-gmc.org/GMCropDatabase), as well as in patent applications, like EP3028573 and WO2017/011288.
The use of herbicidal compositions according to the invention on crops may result in effects which are specific to a crop comprising a certain gene or event. These effects might involve changes in growth behavior or changed resistance to biotic or abiotic stress factors. Such effects may in particular comprise enhanced yield, enhanced resistance or tolerance to insects, nematodes, fungal, bacterial, Mycoplasma, viral or viroid pathogens as well as early vigour, early or delayed ripening, cold or heat tolerance as well as changed amino acid or fatty acid spectrum or content.
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 production, e.g., potatoes that produce increased amounts of amylopectin (e.g. Amflora® potato, BASF SE, Germany).
Furthermore, it has been found that the herbicidal compositions according to the invention 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 herbicidal compositions have been found for the desiccation and/or defoliation of plants, processes for preparing these compositions, and methods for desiccating and/or defoliating plants using the herbicidal compositions according to the invention.
As desiccants, herbicidal compositions according to the invention are suitable in particular 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 the facilitation of 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 pomaceous 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.
The herbicidal composition may be applied in or on permanent cropland, or on permanent crops.
A permanent crop is one produced from plants which last for many seasons, rather than being re-planted after each harvest. Permanent crops are grown on permanent crop land in the form of agricultural land that includes grasslands and shrublands, e.g. used to grow grape vines or coffee; orchards used to grow fruit or olives; and forested plantations, e.g. used to grow nuts or rubber. It does not include, however, tree farms intended to be used for wood or timber.
Preferred permanent croplands in the context of the present invention are plantations, grasslands and shrublands. Preferably, the permanent crops in the context of the present invention are plantation crops, and preferably are selected from the group consisting fruit crops and orchard crops (preferably fruit trees, Citrus trees, mango trees, olive trees, grape vines, coffee, cocoa, tea, and berries (such as strawberries, raspberries, blueberries and currants)), Musaceae sp. crops (for example banana or plantain crops), nut trees (preferably almond trees, walnut trees, pistachio trees, pecan trees, hazelnut trees), oil palm trees, rubber trees, sugarcane and cotton.
More preferably, the permanent crops are fruit trees (preferably pome fruit trees and stone fruit trees; preferred fruit trees are apple trees, pear trees, apricot trees, plum trees, cherry trees, peach trees), olive trees, grape vines, coffee, tea), Musaceae sp. crops (preferably banana crops or plantain crops), nut trees (preferably almond trees, walnut trees, pistachio trees, pecan trees, hazelnut trees), oil palm trees, rubber trees, and Citrus crops (preferably lemon, orange or grapefruit crops). Even more preferably, the permanent crops are selected from the group consisting of apple trees, pear trees, apricot trees, plum trees, cherry trees, peach trees, olive trees, grape vines, coffee, tea, banana crops, nut trees (preferably almond trees, walnut trees, pistachio trees), oil palm trees, rubber trees, and Citrus crops (preferably lemon, orange or grapefruit crops). Particularly preferably, the permanent crops are selected from the group consisting of apple trees, pear trees, apricot trees, plum trees, cherry trees, peach trees, olive trees, grape vines, coffee, tea, banana crops, almond trees, walnut trees, oil palm trees, rubber trees, lemon crops, orange crops and grapefruit crops The herbicidal composition may also be applied on row crops and as well on specialty crops.
Row crops can be planted in rows wide enough to allow it to be tilled or otherwise cultivated by agricultural machinery, machinery tailored for the seasonal activities of row crops. The particularity of row crops is that they are planted and cultivated on a seasonal or yearly basis. Therefore, such crops yield products and profit relatively quickly and predictably. A row crop is one produced from plants which last for many seasons, rather than being re-planted after each harvest. Examples of row crops include soybeans, corn, canola, cotton, cereals or rice, but as well sunflower, potato, dry bean, field pea, flax, safflower, buckwheat and sugar beets.
Specialty crops are to be understood as fruits, vegetables or other specialty or plantation permanent crops such as trees, nuts, vines, (dried) fruits, ornamentals, oil palm, banana, rubber and the like, Horticulture and nursery crops, including floriculture, may also fall under the definition of specialty crops. Vegetable crops includes for example aubergine, beans, bell pepper, cabbage, chili, cucumber, eggplant, lettuce, melon, onion, potato, sweet potato, spinach and tomato. Plants being considered specialty crops are in general intensively cultivated. For weed control in vegetable crops, it may be desirable to shield the crops from contact with the spray solution that contains the herbicidal mixture according to the present invention.
In general, the crops which may be treated, may be of conventional origin or may be herbicide tolerant crops, preferably glufosinate tolerant crops. The herbicidal composition shows high herbicidal effects also against select crop plants, such as barley and soybean. This effect can be used to control crop plants in crop rotation methods of previously grown crop cultures. Typically, residual crop plants from previous rotation cycles remain after harvest and continue to grow within the subsequently grown crop variety. This reduces the yield since the crop plants of two different crop rotation cycles compete on the same locus of growth. The herbicidal composition may thus be applied to control residual crop plants from previous crop rotation cycles to allow for a homogeneous coverage with the subsequent crop plant.
In a preferred embodiment, the herbicidal composition is applied once, twice or three times per Gregorian calendar year, i.e. in one application, in two applications or in three applications per year according to the Gregorian calendar. In a preferred embodiment, the herbicidal composition is applied twice per Gregorian calendar year, i.e. in two applications per year according to the Gregorian calendar. In an alternatively preferred embodiment, the herbicidal composition is applied one time per Gregorian calendar year, i.e. in one application per year according to the Gregorian calendar. In a preferred embodiment, the herbicidal composition is applied one time in about 12 months, i.e. in one application in about 12 months. In an alternative preferred embodiment, the herbicidal composition is applied between one and ten times per Gregorian calendar year, i.e. in up to ten applications per year according to the Gregorian calendar. This alternative preferred method is of particular usefulness in permanent crops, in particular those grown under tropical conditions; in which case weeds grow vigorously at any time of the year, and herbicide applications are to be re-peated as soon as the previous treatment loses its effectiveness and weeds start to regrow.
The herbicidal compositions are preferably used in post-emergence applications.
The invention includes the use and methods of application of the herbicidal composition for controlling undesirable vegetation in crops in a burndown program, wherein the crop is produced by genetic engineering or by breeding, are tolerant to one or more herbicides and/or resistant to pathogens such as plant-pathogenous fungi, and/or to attack by insects; preferably tolerant to glufosinate.
Preferred are crops, which are tolerant to glufosinate, wherein the glufosinate tolerant crop plant is preferably selected from the group consisting of rice, canola, soybean, corn and cotton plants.

The herbicidal compositions have an outstanding herbicidal activity against a broad spectrum of economically important harmful monocotyledonous and dicotyledonous harmful plants. Also here, post-emergence application is preferred.
Specifically, examples may be mentioned of some representatives of the monocotyledonous and dicotyledonous weed flora which can be controlled by the combinations according to the invention, without the enumeration being a restriction to certain species.
In the context of the present text, reference may be made to growth stages according to the BBCH monograph “Growth stages of mono- and dicotyledonous plants”, 2nd edition, 2001, ed.

In a preferred embodiment, the herbicidal compositions are used to control monocotyledonous harmful plant species, more preferably monocoty-ledonous plants of the species Echinochloa spp., Digitaria spp., Setaria spp., Eleusine spp. and Bra-chiarium spp.
Examples of dicotyledonous harmful plants on which the herbicidal compositions act efficiently are from amongst the genera Amaranthus spp., Erigeron spp., Conyza spp., Polygonum spp., Medicago spp., Mollugo spp., Cyclospermum spp., Stellaria spp., Gnaphalium spp., Taraxacum spp., Oenothera spp., Amsinckia spp., Erodium spp., Erigeron spp., Senecio spp., Lamium spp., Kochia spp., Chenopodium spp., Lactuca spp., Malva spp., Ipomoea spp., Brassica spp., Sinapis spp., Urtica spp., Sida spp, Portulaca spp., Richardia spp., Ambrosia spp., Calandrinia spp., Sisymbrium spp., Sesbania spp., Capsella spp., Sonchus spp., Euphorbia spp., Helianthus spp., Coronopus spp., Salsola spp., Abutilon spp., Vicia spp., Epilobium spp., Cardamine spp., Picris spp., Trifolium spp., Galinsoga spp., Epimedium spp., Marchantia spp., Solanum spp., Oxalis spp., Metricaria spp., Plantago spp., Tribulus spp., Cenchrus spp. Bidens spp., Veronica spp., and Hypochaeris spp.
Particular examples of dicotyledonous harmful plants species on which the herbicidal compositions act efficiently are selected from amongst the species Amaranthus spinosus, Polygonum convolvulus, Medicago polymorpha, Mollugo verticillata, Cyclospermum leptophyllum, Stellaria media, Gnaphalium purpureum, Taraxacum offi cinale, Oenothera laciniata, Amsinckia intermedia, Erodium cicutarium, Erodium moschatum, Erigeron bonariensis (Conyza bonariensis), Senecio vulgaris, Lamium amplexicaule, Erigeron canadensis, Polygonum aviculare, Kochia scoparia, Chenopodium album, Lactuca serriola, Malva parviflora, Malva neglecta, Ipomoea hederacea, Ipomoea lacunose, Brassica nigra, Sinapis arvensis, Urtica dioica, Amaranthus blitoides, Amaranthus retroflexus, Amaranthus hybridus, Amaranthus lividus, Sida spinosa, Portulaca oleracea, Richardia scabra, Ambrosia artemisiifolia, Calandrinia cau-lescens, Sisymbrium irio, Sesbania exaltata, Capsella bursa-pastoris, Sonchus oleraceus, Euphorbia maculate, Helianthus annuus, Coronopus didymus, Salsola tragus, Abutilon theophrasti, Vicia ben-ghalensis L., Epilobium paniculatum, Cardamine spp, Picris echioides, Trifolium spp., Galinsoga spp., Epimedium spp., Marchantia spp., Solanum spp., Oxalis spp., Metricaria matriccarioides, Plantago spp., Tribulus terrestris, Salsola kali, Cenchrus spp., Bidens bipinnata, Veronica spp., and Hypochaeris radicata.
In a preferred embodiment, the herbicidal compositions are used to control dicotyledonous harmful plant species, more preferably dicotyledonous plants of the species Amaranthus spp., Erigeron spp., Conyza spp., Kochia spp. and Abutilon spp.
Herbicidal compositions are also suitable for controlling a large number of annual and perennial sedge weeds including Cyperus species such as purple nutsedge (Cyperus rotundus L.), yellow nutsedge (Cyperus esculentus L.), hime-kugu (Cyperus brevifolius H.), sedge weed (Cyperus microiria Steud), rice flatsedge (Cyperus iria L.), Cyperus difformis, Cyperus difformis L., Cyperus esculentus, Cyperus ferax, Cyperus flavus, Cyperus iria, Cyperus lanceolatus, Cyperus odoratus, Cyperus rotundus, Cyperus serotinus Rottb., Eleocharis acicularis, Eleocharis kuroguwai, Fimbristylis dichotoma, Fimbristylis miliacea, Scirpus grossus, Scirpus juncoides, Scirpus juncoides Roxb, Scirpus or Bolboschoenus maritimus, Scirpus or Schoenoplectus mucronatus, Scirpus planiculmis Fr. schmidt and the like.
If the herbicidal compositions are applied post-emergence to the green parts of the plants, growth likewise stops drastically a very short time after the treatment and the weed plants remain at the growth stage of the point of time of application, or they die completely after a certain time, so that in this manner competition by the weeds, which is harmful to the crops, is eliminated at a very early point in time and in a sustained manner.
The herbicidal compositions are characterized by a rapidly commencing and long-lasting herbicidal action. As a rule, the rainfastness of the active compounds in the herbicide combinations according to the present invention is advantageous. In particular when the herbicidal compositions are employed application rates may be reduced, a broader spectrum of broad-leaved weeds and grass weeds maybe controlled, the herbicidal action may take place more rapidly, the duration of action may be longer, the harmful plants may be controlled better while using only one, or few, applications, and the application period which is possible to be extended.
The abovementioned properties and advantages are of benefit for weed control practice to keep agricultural crops free from undesired competing plants and thus to safeguard and/or increase the yields from the qualitative and/or quantitative point of view. These herbicidal compositions markedly exceed the technical state of the art with a view to the properties described. Owing to their herbicidal and plant-growth-regulatory properties, the herbicidal compositions can be employed for controlling harmful plants in genetically modified crops or crops obtained by mutation/selection. These crops are distinguished as a rule by particular, advantageous properties, such as resistances to herbicidal compositions or resistances to plant diseases or causative agents of plant diseases such as particular insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the harvested material with regard to quantity, quality, storability, composition and specific constituents. Thus, for example, transgenic plants are known whose starch content is increased or whose starch quality is altered, or those where the harvested material has a different fatty acid composition.
The present invention also relates to a method of controlling undesired vegetation (e.g. harmful plants), which comprises applying the herbicidal compositions, preferably by the post-emergence method, to harmful or undesired plants, parts of said harmful or undesired plants, or the area where the harmful or undesired plants grow, for example the area under cultivation.
In the context of the present invention “controlling” denotes a significant reduction of the growth of the harmful plant(s) in comparison to the untreated harmful plants. Preferably, the growth of the harmful plant(s) is essentially diminished (60-79%), more preferably the growth of the harmful plant(s) is largely or fully suppressed (80-100%), and in particular the growth of the harmful plant(s) is almost fully or fully suppressed (90-100%).
Thus, in a further aspect, the present invention relates to a method for controlling undesired plant growth, and/or controlling harmful plants, comprising the step of applying the herbicidal composition (preferably in one of the preferred embodiments defined herein) onto the undesired plants or the harmful plants, on parts of the undesired plants or the harmful plants, or on the area where the undesired plants or the harmful plants grow.
The herbicidal composition(s) may be used for controlling undesirable vegetation in burndown programs, in industrial vegetation management and forestry, in vegetable and perennial crops and in turf and lawn, wherein the herbicidal composition(s) can be applied pre- or post-emergence, i.e. before, during and/or after emergence of the undesirable plants. Preferred is the application as post-emergence treatment, i.e. during and/or after emergence of the undesirable plants. Herein, the herbicidal composition(s) are applied to a locus where crops will be planted before planting or emergence of the crop.
In industrial weed management and forestry, it is desirable to control a broad range of weeds for an extended period of time. The control of large weeds, or taller species such as bushes or trees may also be desirable. Industrial weed management includes for example railway and right-of-way management, fence lines and non-crop land such as industrial and building sites, gravel areas, roads or sidewalks. Forestry includes for example the clearing of existing forest or bushland, the removal of regrowth after mechanical forest cutting, or the management of weeds under forestry plantations. In the latter case, it may be desirable to shield desirable trees from contact with the spray solution that contains the herbicidal mixture according to the present invention.
The herbicidal composition can also be used for weed control in turf and lawn provided the desirable grass species are tolerant to herbicidal composition. In particular, such herbicidal compositions can be used in desirable grass that has been rendered tolerant to the respective agrochemical active ingredient, e.g. glufosinate or its salts, by mutagenesis or genetic engineering.
Glufosinate and its salts are non-selective systemic herbicides having a good post-emergence activity against numerous weeds and thus can be used in burndown programs, in industrial vegetation management and forestry, in vegetable and perennial crops and in turf and lawn.
Therefore, the present invention also relates to a method for burndown treatment of undesirable vegetation in crops, comprising applying the herbicidal composition, to a locus where crops will be planted before planting (or seeding) or emergence of the crop. Herein, the herbicidal composition is applied undesirable vegetation or the locus thereof.
The present invention also relates to a method for controlling undesirable vegetation, which method comprises applying the herbicidal composition, to a locus where undesirable vegetation is present or is expected to be present. The application may be done before, during and/or after, preferably during and/or after, the emergence of the undesirable vegetation. In one embodiment, the application is carried out before emergence of the crop, which is cultivated at the locus where the undesirable vegetation is present or is expected to be present. In another embodiment, the application is carried out before planting the crop.
As used herein, the terms “controlling” and “combating” are synonyms.
As used herein, the terms “undesirable vegetation”, “undesirable species”, “undesirable plants”, “harmful plants”, “undesirable weeds”, or “harmful weeds” are synonyms.
The term “locus”, as used herein, means the area in which the vegetation or plants are growing or will grow, typically a field.
In burndown programs, the herbicidal composition(s) can be applied prior to seeding (planting) or after seeding (or planting) of the crop plants but before the emergence of the crop plants, in particular prior to seeding. The herbicidal compositions are preferably applied prior to seeding of the crop plants. For burndown, the herbicidal composition(s) will generally be applied a date up to 9 months, frequently up to 6 months, preferably up to 4 months prior to planting the crop. The burndown application can be done at a date up to 1 day prior to emergence of the crop plant and is preferably done at a date prior to seeding/planting of the crop plant, preferably at a date of at least one day, preferably at least 2 days and in particular at least one 4 days prior to planting or from 6 months to 1 day prior emergence, in particular from 4 months to 2 days prior emergence and more preferably from 4 months to 4 days prior emergence. It is, of course, possible to repeat the burndown application once or more, e.g. once, twice, three times, four times or five times within that time frame.
It is a particular benefit of the herbicidal compositions that they have a very good post-emergence herbicide activity, i.e. they show a good herbicidal activity against emerged undesirable plants. Thus, in a preferred embodiment of invention, the herbicidal compositions are applied post-emergence, i.e. during and/or after, the emergence of the undesirable plants. It is particularly advantageous to apply the herbicidal composition post emergent when the undesirable plant starts with leaf development up to flowering. The herbicidal compositions are particularly useful for controlling undesirable vegetation which has already developed to a state, which is difficult to control with conventional burndown mixtures, i.e. when the individual weed is taller than 10 cm (4 inches) or even taller than 15 cm (6 inches) and/or for heavy weed populations.
In the case of a post-emergence treatment of the plants, the herbicidal compositions are preferably applied by foliar application.
The herbicidal compositions can be applied in conventional manner by using techniques as skilled person is familiar with. Suitable techniques include spraying, atomizing, dusting, spreading or watering. The type of application depends on the intended purpose in a well-known manner; in any case, they should ensure the finest possible distribution of the active ingredients according to the invention.
In one embodiment, the herbicidal compositions are applied to locus mainly by spraying, in particular foliar spraying of an aqueous dilution of the active ingredients of the mixture. Application can be carried out by customary spraying techniques using, for example, water as carrier and spray liquor rates of from about 10 to 2000 I/ha or 50 to 1000 I/ha (for example from 100 to 500 I/ha). Application of the inventive mixtures by the low-volume and the ultra-low-volume method is possible, as is their application in the form of microgranules.
The required application rate of the herbicidal composition depends on the density of the undesired vegetation, on the development stage of the plants, on the climatic conditions of the location where the mixture is used and on the application method.
In general, the rate of application of L-glufosinate or its salt is usually from 50 g/ha to 3000 g/ha and preferably in the range from 100 g/ha to 2000 g/ha or from 200 g/ha to 1500 g/ha of active substance (a.i.).
When using the herbicidal composition in the methods of the present invention, the glufosinate or a salt thereof and the compound of formula (I) can be applied simultaneously or in succession, where undesirable vegetation may occur. Herein, it is immaterial whether the individual compounds present in the inventive mixtures are formulated jointly or separately and applied jointly or separately, and, in the case of separate application, in which order the application takes place. It is only necessary, that the individual compounds present in the inventive mixtures are applied in a time frame, which allows simultaneous action of the active ingredients and/or the compound of formula (I) on the undesirable plants.
The herbicidal compositions show a persistent herbicidal activity, even under difficult weathering conditions, which allows a more flexible application in burndown applications and minimizes the risk of weeds escaping. Apart from that, the herbicidal compositions show superior crop compatibility with certain conventional crop plants and with herbicide tolerant crop plants, i.e. their use in these crops leads to a reduced damage of the crop plants and/or does not result in increased damage of the crop plants. Thus, the herbicidal compositions can also be applied after the emergence of the crop plants. The herbicidal compositions may also show an accelerated action on harmful plants, i.e. they may affect damage of the harmful plants more quickly.
The herbicidal compositions are also suitable for controlling weeds that are resistant to commonly used herbicides such as, for example, weeds that are resistant to glyphosate, weeds that are resistant to auxin inhibitor herbicides such as e. g. 2,4-D or dicamba, weeds that are resistant to photosynthesis inhibitors such as e. g. atrazine, weeds that are resistant to ALS inhibitors such as e. g. sulfonylureas, imidazolinones or triazolopyrimidines, weeds that are resistant to ACCase inhibitors such as e. g. clodinafop, clethodim or pinoxaden or weeds that are resistant to protoporphyrinogen-IX-oxidase inhibitors such as e. g. sulfentrazone, flumioxazine, fomesafen or acifluorfen, for example the weeds that are listed in the International Survey of Resistant Weeds (http://www.weedscience.org/Summary/SpeciesbySOATable.aspx).

The herbicidal compositions are suitable for combating/controlling common harmful plants in fields, where useful plants shall be planted (i.e. in crops). The inventive mixtures are generally suitable, such as for burndown of undesired vegetation, in fields of the following crops: Grain crops, including e.g. cereals (small grain crops) such as wheat (Triticum aestivum) and wheat like crops such as durum (T. durum), einkorn (T. monococcum), emmer (T. dicoccon) and spelt (T. spelta), rye (Secale cereale), triticale (Tritiosecale), barley (Hordeum vulgare); maize (corn; Zea mays); Sorghum (e.g. Sorghum bicolour); rice (Oryza spp. such as Oryza sativa and Oryza glaberrima); and sugar cane;
Legumes (Fabaceae), including e.g. soybeans (Glycine max.), peanuts (Arachis hypogaea and pulse crops such as peas including Pisum sativum, pigeon pea and cowpea, beans including broad beans (Vicia faba), Vigna spp., and Phaseolus spp. and lentils (Lens culinaris var.); brassicaceae, including e.g. canola (Brassica napus), oilseed rape (OSR, Brassica napus), cabbage (B. oleracea var.), mustard such as B. juncea, B. campestris, B. narinosa, B. nigra and B. tournefortii; and turnip (Brassica rapa var.);
other broadleaf crops including e.g. sunflower, cotton, flax, linseed, sugarbeet, potato and tomato;
TNV-crops (TNV: trees, nuts and vine) including e.g. grapes, Citrus, pomefruit, e.g. apple and pear, coffee, pistachio and oilpalm, stonefruit, e.g. peach, almond, walnut, olive, cherry, plum and apricot;
turf, pasture and rangeland; onion and garlic;
bulb ornamentals such as tulips and Narcissus;
conifers and deciduous trees such as Pinus, fir, oak, maple, dogwood, hawthorne, crabapple, and Rhamnus (buckthorn); and garden ornamentals such as roses, Petunia, marigold and snapdragon.
In one embodiment, the method for controlling undesired vegetation is applied in cultivated rice, maize, pulse crops, cotton, canola, small grain cereals, soybeans, peanut, sugarcane, sunflower, plantation crops, tree crops, nuts or grapes. In another embodiment, the method is applied in cultivated crops selected from glufosinate-tolerant crops.
The herbicidal are in particular suitable for burndown of undesired vegetation in fields of the following crop plants: small grain crops such as wheat, barley, rye, triticale and durum, rice, maize (corn), sugarcane, Sorghum, soybean, pulse crops such as pea, bean and lentils, peanut, sunflower, sugarbeet, potato, cotton, Brassica crops, such as oilseed rape, canola, mustard, cabbage and turnip, turf, pasture, rangeland, grapes, pomefruit, such as apple and pear, stonefruit, such as peach, almond, walnut, pecans, olive, cherry, plum and apricot, Citrus, coffee, pistachio, garden ornamentals, such as roses, Petunia, marigold, snap dragon, bulb ornamentals such as tulips and Narcissus, conifers and deciduous trees such as Pinus, fir, oak, maple, dogwood, hawthorne, crabapple and Rhamnus.
The herbicidal compositions are most suitable for burndown of undesired vegetation in fields of the following crop plants: small grain crops such as wheat, barley, rye, triticale and durum, rice, maize, sugarcane, soybean, pulse crops such as pea, bean and lentils, peanut, sunflower, cotton, Brassica crops, such as oilseed rape, canola, turf, pasture, rangeland, grapes, stonefruit, such as peach, almond, walnut, pecans, olive, cherry, plum and apricot, Citrus and pistachio.
The invention also relates to plant propagation material comprising the herbicidal composition; and to a method for treating plant propagation material comprising the step of treating plant propagation material with the herbicidal composition.
In treatment of plant propagation materials such as seeds, e. g. by dusting, coating or drenching seed, amounts of glufosinate or salt thereof 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 propagation material (preferably seeds) are generally required.
The treatment of plant propagation material comprises the step of contacting the plant propagation material with the herbicidal composition. The contacting may be carried out by 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 herbicidal compositions. 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. Preferably, the term seed refers to a seed of a modified plant that is resistant against glufosinate.
Further objects of the invention are the use of the amine component for increasing the herbicidal activity of liquid herbicidal compositions comprising glufosinate, or a salt thereof, and a compound of formula (I); and a method for increasing the herbicidal activity of liquid herbicidal compositions comprising glufosinate or a salt thereof, and a compound of formula (I) comprising the step of contacting the liquid herbicidal composition with the amine component. The term “increasing the herbicidal activity” refers to an enhanced controlling of undesired vegetation as compared to a composition lacking the amine component. The increased controlling rate may typically be an enhancement of at least 10%, preferably at least 25% as compared to a composition lacking the amine component. The contacting in the method of application usually refers to admixing the amine component to the composition.
Advantages: the herbicidal compositions have an enhanced biological effect on undesired vegetation as compared to liquid glufosinate formulations that contain a compound of formula (I) but not containing the amine component. Another advantage is the reduced damage of certain crop plants by the herbicidal composition, and a defoliation effect on other crop plants. Further advantages are a higher loading with glufosinate, lower application rates, and higher maximum concentrations with compounds of formula (I).
The following examples illustrate the invention.
Pesticide A: ammonium salt of glufosinate
Adjuvant A: aqueous solution of alkylpolyglycosides, based on C8-C19-alcohol
Additive A: sodium laurylethersulfate containing two molecules of polymerized ethylene oxide, 70 wt % in water
Four compositions according to the invention A1 to A4, as well as four comparative compositions AC1 to AC4 were prepared by mixing the ingredients at the concentrations as provided in Tables A and B.
The compositions A1 to A4, and AC1 to AC4 as prepared in Example-1 were tested for their biological effect on the crops spring barley, Hordeum vulgare var. Adonis, and soybean, Glycine max var. Sultana. To this end, spring barley was grown to growth stage of 12/13 according to the BBCH scale. Soybean plants were grown to growth stages 14/15 according to the BBCH scale. Directly before application the plants were watered as needed. Application of the herbicidal compositions was carried out in a spraying chamber. The herbicidal compositions were diluted with water and applied in a rate of 200 liters/hectare. The amount of Pesticide A applied is listed in Tables C, C, E and F. After application the plant remained for 30 minutes minimum in a drying tunnel (air flow volume 3000 m3/h) to get the surface of the plants complete dry before putting them in the greenhouse. The herbicidal activity was evaluated 7 and 20 days after treatment by awarding scores to the treated plants in comparison to the untreated control plants (Tables C, D, E and F). The evaluation scale ranges from 0% go 100% activity. 100% activity means the complete death of at least those parts of the plant that are above ground. Conversely, 0% activity means that there were no differences between treated and untreated plants. Experiments that were carried out on the same days at the same time have the same letter in brackets in Tables C, D, E and F.
