Description

SYNERGETICALLY ACTIVE HERBICIDE COMPOSITION INCLUDING METOBROMURON AND PYRAFLUFEN ETHYL

TECHNICAL FIELD

The invention relates to a synergistically active herbicide composition comprising metobromuron and pyraflufen-ethyl, to a kit comprising metobromuron and pyraflufen-ethyl and to a use of a herbicide composition according to the invention for controlling one or more types of undesired plant growth.

BACKGROUND

The use of metobromuron as a herbicide is known in the prior art. The herbicide action of metobromuron herbicides against undesired plant growth is already at a high level, but generally depends on the dosage, the respective preparation form, the respective undesired plant growth to be controlled or the spectrum of undesired plant growth, the climate and soil conditions and so on. Therefore, there is often a need for targeted synergistic activity against specific types of undesired plant growth, combating undesired plant growth with better overall selectivity, generally smaller amounts of active compounds used for equally good control results and for a reduced supply of active compounds to the environment, for example. avoid rinsing and transfer effects. However, with the combined use of a plurality of active compounds, there are often phenomena of chemical, physical or biological incompatibility, for example, decomposition of an active compound or antagonism in the biological activity of the active compounds.

The present invention is directed to solving at least some of the aforementioned problems. Furthermore, it is an object of the present invention to provide herbicide compositions as an alternative to, or as an improvement to, the prior art.

SUMMARY OF THE INVENTION

A first aspect of the present invention provides a synergistically effective herbicide composition according to the preamble of claim 1.

BE2018 / 5461

In the herbicide composition of the first aspect of the present invention, metobromuron has exhibited an unexpected increase in herbicide activity when combined with pyraflufen-ethyl. This increase in herbicide activity is caused by a synergistic effect in combining metobromuron and pyraflufen-ethyl according to a weight ratio according to the first aspect of the present invention.

A second aspect of the present invention provides a kit according to the preamble of claim 5.

A third aspect of the present invention provides a use according to the preamble of claim 7.

DETAILED DESCRIPTION OF THE INVENTION

The indication of numerical ranges by means of one or two end points contains all numbers and fractions that fall within that range, as well as the one or two end points mentioned.

The term "unwanted plant growth" as used herein refers to all plants, such as, for example, large-leaved weeds, weed grasses, or cyperaceae, which grow in places where they are undesirable.

The terms "urea herbicide" and "carbamide herbicide" as used herein are synonymous and include selective herbicides for controlling undesirable plant growth belonging to the C2 classification according to the Herbicide Resistance Action Committee (HRAC) (http: // www. hracglobal.com).

Urea herbicides are urea derivatives and belong to the class of photosystem II inhibitors. The class of urea herbicides contains anisuron, buturon, chlorobromuron, chlorotururon, chlorxuron, diphenoxuron, dimefuron, diuron, fenuron, fluometuron, isoproturon, linuron, methiouron, metobenzuron, metobromuron, metoxuron, monobonuron, paronuron, monolinuron, mononuron , thidiazuron and derivatives thereof.

As used herein, the term "photosystem II inhibitors" refers to chemical compounds that have a herbicide action by inhibiting the photosynthesis process at the level of photosystem II in plants. In

BE2018 / 5461 in particular, photo system II inhibitors inhibit the binding of quinone to the D1 protein of photo system II, causing electrons to accumulate in chlorophyll molecules and causing an excess of oxidation and causing the plant to die. The class of substances of the photosystem II inhibitors includes triazinone herbicides, urea herbicides, phenyl carbamate herbicides, triazolinone herbicides, nitrile herbicides, amide herbicides, benzothiadiazinone herbicides, phenyl pyridazine herbicides and derivatives thereof.

As used herein, the term "phenylpyrazoles" refers to one or more compounds selected from the group consisting of ethiprol, fipronil, flufiprol, pyrafluprool, pyriprool, fluazolate, nipyraclofen, pinoxads, pyraflufen and pyraflufenethyl.

The term "protective agent", as used in this text, is to be understood as a compound or a mixture of compounds that compensates for or reduces the phytotoxic properties of a herbicide with regard to beneficial plants without substantially reducing the herbicide action against unwanted plant growth. to decrease.

The herbicide action of herbicides comprising metobromuron or metobromuron herbicides against unwanted plant growth (including large-leaved weeds, weed grasses, Cyperaceae) is already at a high level, but generally depends on the dosage, the respective preparation form, the respective unwanted plant growth to be controlled or the spectrum unwanted plant growth, climate and soil conditions and so on. Further criteria in this context are the duration of action, or the rate of degradation, of the herbicide, the general compatibility with the crop and the rate of action (faster start of action), the activity spectrum and behavior with regard to succeeding crops (replanting problems) or the general flexibility of application. (combating unwanted plant growth in its various growth stages). If applicable, changes in the susceptibility of unwanted plant growth that may occur with long-term use of the herbicides or in limited geographical areas may also have to be taken into account (control of tolerant or resistant species of unwanted plant growth). Compensation for losses of activity in the case of individual plants of undesired plant growth by increasing the doses of the herbicides is only possible to a certain extent, for example because such a procedure

BE2018 / 5461 reduces selectivity of the herbicides or because the effect is not improved, even when using higher doses.

Therefore, there is often a need for targeted synergistic activity against specific types of unwanted plant growth, control of unwanted plant growth with better overall selectivity, generally lower amounts of active compounds used for equally good control results and for a reduced supply of active compounds to the environment to for example, to avoid rinsing and transfer effects. There is also a need for the control of species that have not been controlled so far (gaps) and for the control of species that are tolerant or resistant to individual herbicides or to a number of herbicides. There is also a need to develop one-off applications to avoid labor-intensive multiple applications, and also to develop systems for controlling the operating speed, where in addition to an initial rapid control of unwanted plant growth, there is also a slow residual control.

A possible solution to the above mentioned problems may be to provide combined herbicide compositions, i.e. combinations of a plurality of herbicides and / or other components from the group of agrochemically active compounds of different types and to formulation auxiliaries and additives that are customary are in crop protection and that contribute to the desired additional properties. However, with the combined use of a plurality of active compounds, there are often phenomena of chemical, physical or biological incompatibility, for example, decomposition of an active compound or antagonism in the biological activity of the active compounds. For these reasons, suitable combinations of active compounds may need to be selected in a targeted way and tested for their suitability, since it is not possible to rule out negative or positive results in advance.

A first aspect of the present invention provides a synergistically effective herbicide composition comprising as component (A) a herbicide-effective amount of metobromuron and as component (B) pyraflufenethyl, wherein a weight ratio of components (A) and (B) in a range of up to 1000: 1, more preferably up to 900: 1, more preferably up to 800: 1, more preferably up to 700: 1, more preferably up to 600: 1, more preferably up to 500: 1, even more preferably up to 400: 1 and with even more preferable to

BE2018 / 5461

350: 1. In a preferred embodiment, the weight ratio of components (A) and (B) is in a range of up to 300: 1, more preferably up to 299: 1, even more preferably up to 290: 1 and even more preferably up to 280: 1. In a preferred embodiment, the weight ratio of components (A) and (B) is in a range of 10: 1 to 270: 1, more preferably from 30: 1 to 200: 1, even more preferably from 60: 1 to 130: 1, even more preferably from 70: 1 to 120: 1, even more preferably from 80: 1 to 110: 1 and most preferably from 90: 1 to 100: 1.

In the herbicide composition of the first aspect of the present invention, metobromuron has exhibited an unexpected increase in herbicide activity when combined with pyraflufen-ethyl. This increase in herbicide activity is caused by a synergistic effect in combining metobromuron and pyraflufen-ethyl according to said weight ratio. Metobromuron and pyraflufen-ethyl interact with each other in a particularly favorable manner, for example when they are used to control undesired plant growth in seeded and / or planted crops, lawns / lawns, in fruit plantations (plantation crops) or areas without crops (e.g. squares in residential areas or industrial locations, railways). Surprisingly, the activity of the combination according to the invention of two active compounds when used against undesired plant growth is higher than the activities of the individual components. So there is a true synergistic effect that could not be predicted, not just a supplement of effect (additive effect). For controlling undesired plant growth, it is particularly advantageous to use the herbicide composition according to the first aspect of the present invention in dilute form in water.

Metobromuron (IUPAC name: 3- (4-bromophenyl) -1-methoxy-1-methylurea) is a chemical compound from the phenylurea group and can also be classified as a member of the urea herbicides or carbamide herbicides, and belongs to the class of the photo system II inhibitors. Metobromuron can be obtained from pbroomaniline and phosgene. The product thereof further reacts with N, Odimethylhydroxylamine to obtain the final product. Metobromuron can be used as a pre-emergence herbicide in potato, tobacco, tomato, common bean, lamb's lettuce, soybean and sunflower crops. In addition, metobromuron has an after-emergence effect and can therefore also be used as a post-emergence herbicide.

BE2018 / 5461 Pyraflufen-ethyl (IUPAC name: ethyl-2-chloro-5- (4-chloro-5-difluoromethoxy-1-methylpyrazol-3-yl) -4-fluorophenoxyacetate) is a chemical compound from the group of phenylpyrazoles. Pyraflufen-ethyl can be obtained from 5 (ethoxycarbonylmethoxy) benzoyl acetate by cyclocondensation with methylhydrazine to 3-aryl-5-hydroxypyrazole, which is converted to the final product by O-difluoromethylation and chlorinated with phosphorus pentachloride.

Pyraflufen-ethyl is a colorless, odorless solid. It is stable and acidic, but hydrolyses slowly under neutral conditions and rapidly under basic conditions. It is derived as the ethyl ester of pyraflufen. Pyraflufen-ethyl is used as an active ingredient in crop protection products. Pyraflufen-ethyl can be used as a post-emergence herbicide, but it also has a pre-emergence effect. It can be used as a defoliant for cotton and potatoes and for controlling certain large-leaved weeds in cotton, corn, soybeans, wheat and in non-agricultural areas. It works by inhibiting protoporphinogen IX oxidase and thereby causing damage to cell membranes.

The synergistic effect of metobromuron and pyraflufen-ethyl can be observed, for example, in the case of a premixed application, for example as a ready-to-use (RTU) formulation, an emulsifiable concentrate (EC) formulation, micro - emulsifiable concentrate, formulation in the form of an oil dispersion (OD), formulation in the form of a wettable powder (WP, wetable powder), water-dispersible granulate (WG), formulation in the form of a water-soluble granulate (SG "soluble granule"), and in the case of a co-formulation or as a tank mixture. However, it can also be observed when the active compounds are applied at different times (temporary delayed application) (packaged as, for example, a combination package or single doses). It is also possible to use the herbicides or the herbicide composition in a plurality of portions (sequential application), for example post-emergence applications or early post-emergence applications followed by medium or late post-emergence applications. When metobromuron and pyraflufen-ethyl are used as a tank mixture, it must be ensured that a spray liquid obtained is used relatively quickly after preparation.

In a preferred embodiment, the herbicide composition according to the first aspect of the present invention further comprises one or more additional

BE2018 / 5461 ingredients selected from the group comprising other pesticides such as herbicides, insecticides, fungicides or other active pesticide ingredients, protectors, antioxidants, chemical stabilizers, adhesives, fertilizers, fragrances, dyes, liquid carriers, solid carriers, surfactants, crystallization inhibitors, viscosity adjusters, suspending agents, spray-drip modifying agents, pigments, foaming agents, light-blocking agents, compatibility agents, anti-foaming agents, sequestering agents, neutralizing agents and buffers, wetting and dispersing agents, preservatives, thickeners, corrosion inhibitors, freezing point inhibitors, odorants, dispersants, penetrating agents emollients, lubricants, adhesives and wetting agents, such as, for example, propylene glycol.

A wide range of surfactants is advantageously used in both liquid and solid compositions, particularly those that are designed to be diluted with carrier prior to use. Surfactants, also known as surfactants, are compounds that reduce the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. Surfactants can be anionic, cationic, non-ionic or polymeric in nature and can act as detergents, wetting agents, emulsifiers, foaming agents and dispersants. Many organic compounds exhibit some surfactant properties, but non-ionic surfactants can be used specifically for the purposes of the invention. The most important of these are the fatty alcohols, such as cetyl alcohol, stearyl alcohol and cetostearyl alcohol (mainly consisting of cetyl and stearyl alcohol) and oleyl alcohol; but also polyethylene glycol alkyl ethers such as octaethylene glycol monododecyl ether and pentaethylene glycol monododecyl ether; polypropylene glycol alkyl ethers; polyethylene glycol-polypropylene glycol alkyl ethers; glucoside alkyl ethers such as decyl glucoside, lauryl glucoside or octyl glucoside; polyethylene glycol octylphenyl ethers; polyethylene glycol nonyl phenyl ethers; polyethylene glycol tributyl phenyl ethers; polyethylene glycol tristyrylphenyl ethers; polyethylene glycol-polypropylene glycol tristyrylphenyl ethers; glycerol alkyl esters such as glyceryl laurate; polyoxyethylene glycol sorbitan alkyl esters such as polysorbates; sorbitan alkyl esters, such as spans; cocamide MEA or DEA; dodecyldimethylamine oxide; block copolymers of polyethylene glycol and polypropylene glycol, such as poloxamers; polyethoxylated tallow amine (POEA); vegetable oil ethoxylates, such as castor oil ethoxylates, rapeseed oil ethoxylates, soybean oil ethoxylates; and the like, salts of alkyl sulfates, such as diethanol ammonium lauryl sulfate; alkylaryl sulfonate salts, such as calcium dodecyl benzene sulfonate; soaps, such as sodium stearate; alkyl naphthalene sulfonate salts, such as sodium dibutyl naphthalene sulfonate; dialkyl esters of sulfosuccinate salts, such as sodium di- (2-ethylhexyl) sulfosuccinate; salts of mono- and dialkyl phosphate esters; quaternary amines such as lauryl trimethyl ammonium chloride and the like.

The compositions can be formulated with liquid and solid fertilizers, such as particulate fertilizers such as ammonium nitrate, urea and the like.

Preferably, the concentration ranges of metobromuron are prepared by mixing a suspension concentrate of metobromuron with water. Preferably, the concentration ranges of pyraflufen-ethyl are prepared by mixing an emulsifiable concentrate of pyraflufen-ethyl with water.

In another aspect of the present invention, the invention provides a synergistically active herbicide composition comprising as component (A) a herbicide-effective amount of metobromuron and as component (B) oxyfluorphs, wherein a weight ratio of components (A) and (B) in a range of up to 1000 : 1, more preferably up to 900: 1, more preferably up to 800: 1, more preferably up to 700: 1, more preferably up to 600: 1, more preferably up to 500: 1, even more preferably up to 400: 1 1 and even more preferably up to 350: 1. In a preferred embodiment, the weight ratio of components (A) and (B) is in a range of up to 300: 1, more preferably up to 250: 1, even more preferably up to 200: 1, even more preferably up to 150: 1, with even more preferably up to 120: 1, even more preferably up to 90: 1 and even more preferably up to 60: 1.

In the herbicide composition comprising metobromuron and oxyfluorphs according to another aspect of the present invention, metobromuron has exhibited an unexpected increase in herbicide activity when combined with oxyfluorphs. This increase in herbicide activity is caused by a synergistic effect in combining metobromuron and oxyfluorphs according to said weight ratio. Metobromuron and oxyfluorphs interact with each other in a particularly favorable manner, for example when they are used to control undesired plant growth in seeded and / or planted crops, lawns / lawns, in fruit plantations (plantation crops) or areas without crops (e.g. squares in residential areas or industrial locations, railways).

BE2018 / 5461

Surprisingly, the activity of the combination according to the invention of two active compounds when used against undesired plant growth is higher than the activities of the individual components. So there is a true synergistic effect that could not be predicted, not just a supplement of effect (additive effect). For controlling undesired plant growth, it is particularly advantageous to use the herbicide composition according to the first aspect of the present invention in dilute form in water, such as, for example, as a tank mixture comprising both metobromuron and oxyfluorphs.

Oxyfluorphs (IUPAC name: 2-chloro-1- (3-ethoxy-4-nitrophenoxy) -4 (trifluoromethyl) benzene) is a chemical compound that belongs to the chemical group of diphenyl ethers. Oxyfluorphs can be prepared by reacting 3,4-dichlorobenzotrifluoride with resorcinol; the resulting product is then treated with ethanol in the presence of potassium hydroxide. Oxyfluorfen is a selective herbicide that can be used against annual grass, large-leaved weeds, perennial weeds and annual weeds in the cultivation of rice, cotton, grapes, peanuts, vegetables, fruits, such as apples, and ornamental plants, and also for pest control of unwanted plant growth on driveways and similar surfaces. Oxyfluorfen exhibits both pre-emergence and targeted post-emergence activity.

It is worth noting that combining metobromuron with oxyfluorphs improves the prevention of unwanted plant growth. In addition, combining oxyfluorphs with metobromuron improves post-emergence control of unwanted plant growth.

The herbicide composition comprising metobromuron and oxyfluorphs can be used as such, in formulations thereof or in the forms of use prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granulates. The herbicide composition can be used in the form of finished formulations.

The good herbicide action of the herbicide composition of the present invention can be seen from the following examples. Although the

BE2018 / 5461 individual active compounds exhibit weaknesses in their herbicide action, all combinations show a very good effect on undesired plant growth that exceeds a simple sum of action.

A synergistic effect in herbicides is always present when the herbicide action of the combination of active compounds exceeds the action of the active compounds used individually.

The expected activity of a given combination of two or three herbicides can be calculated as follows according to a Colby calculation method (cf. COLBY, SR: Calculating synergistic and antagonistic responses or herbicidal combinations ”, Weeds 15, pp. 20-22, 1967) :

If X =% damage due to herbicide (A) at a dosage of m g / ha,

Y =% damage from herbicide (B) at a dosage of n g / ha,

E = the expected damage due to herbicides (A) and (B) at doses of m and n kg / ha, then a combination applies:

E = X + y - (X X Y) / 100

If the actual damage is greater than the calculated value, the activity of the combination is super-additive, i.e. it exhibits a synergistic effect. In this case, the actual observed damage must be greater than the value calculated with the above formulas for the expected damage E.

BE2018 / 5461

EXAMPLES

The invention is further described with reference to the following non-limiting example, which further illustrates the invention and which is neither intended nor intended to be limiting of the scope of the invention.

EXAMPLE 1

The herbicide action of a herbicide composition according to the first aspect of the present invention with respect to various types of undesired plant growth is shown in Table 1. Individual compositions comprising metobromuron or pyraflufen-ethyl are compared with a herbicide composition according to the invention comprising metobromuron and pyraflufen-ethyl. The expected activity of the combination of the active compounds metobromuron and pyraflufen-ethyl is calculated according to the above-mentioned calculation method of Colby, to evaluate a synergistic effect between metobromuron and pyraflufen-ethyl. If the actual herbicide effect is greater than the calculated value, then the activity of the combination is super-additive, i.e. it exhibits a synergistic effect.

The herbicide effect was determined by applying herbicide compositions to emerged unwanted plant growth, shortly before the emergence of potatoes in a field. Metobromuron and pyraflufen-ethyl were used as a tank mix by mixing these active compounds in a spray tank prior to use. The corresponding mixture was in the form of a spray liquid and was sprayed using slit nozzles. In addition, spray liquids from individual compositions comprising metobromuron or pyraflufen-ethyl were used. Test plants of 5 to 15 cm high undesired plant growth were sprayed with the active compound preparations such that certain desired amounts of active compounds per unit area were used.

For this example 1, the results of which are shown below in Table 1, the concentration of the spray liquid is chosen such that certain desired amounts of metobromuron and pyraflufen-ethyl are present in an application volume of 300 l water / ha. At 14 to 36 days after application of the spray liquid, the degree of damage to the undesired plant growth is determined

BE2018 / 5461 in% of plants of unwanted plant growth that were killed, which was assessed by visually checking the plants. The tests were performed on test fields (field tests).

Individual compositions comprising metobromuron or oxyfluorphs are compared with a herbicide composition according to the invention comprising metobromuron and oxyfluorphs. The expected activity of the combination of the active compounds metobromuron and

BE2018 / 5461 oxyfluorphs is calculated according to the above-mentioned calculation method of Colby, to evaluate a synergistic effect between metobromuron and oxyfluorphs. If the actual herbicide effect is greater than the calculated value, then the activity of the combination is super-additive, i.e. it exhibits a synergistic effect.

The herbicide effect was determined by the pre-emergence application of herbicide compositions on a field where apples are grown. Metobromuron and oxyfluorphs were used as a tank mix by mixing these active compounds in a spray tank prior to use. The corresponding mixture was in the form of a spray liquid and was sprayed using slit nozzles. In addition, spray liquids from individual compositions comprising metobromuron or oxyfluorphs were used. The field was sprayed with the active compound preparations such that certain desired amounts of active compounds per unit area were used.

For this example 2, the results of which are shown below in Table 2, the concentration of the spray liquid is chosen such that certain desired amounts of metobromuron and oxyfluorphs are present in an application volume of 300 l water / ha. At 29 days after application of the spray liquid, the degree of damage to the unwanted plant growth is determined in% of plants of unwanted plant growth that were killed, which was assessed by visually checking the plants. The tests were performed on test fields (field tests).
