CN 103329931 describes compositions of indaziflam and glufosinate in a ratio of 1:(0.2 to 10).

The Oregon State University Horticultural Weed Control Report 2012 describes, among other things, weed control in common hazels in Lane County, Oregon, where mixtures of glufosinate and indaziflam were also used.

In their use, herbicidal crop protection agents (herbicides) known today to control weeds or unwanted vegetation, for example in long-term crops or long-term agricultural land, have several disadvantages in that (a) that they do not have or show insufficient herbicidal efficacy against specific weeds, (b) that the range of weeds that can be controlled by herbicides is not wide enough, (c) that herbicide selectivity in plantings and compatibility with (young) crop plants is too low thereby causing an undesirable hazard and/or an undesirable reduction in crop yield of the (young) crop plants, (d) that the initial herbicidal activity is not high or not strong enough, and/or (e) that the herbicidal activity does not last long enough.

Summarizing, herbicidal activity, ie. one or more of the above aspects (a), (b) (c), (d) and/or (e) used herbicides like (L-)glufosinate and/or its agronomically acceptable salts can be improved to some extent .

Surprisingly, it has now been found that certain herbicidal combinations or compositions comprising these herbicidal combinations exhibit the desired herbicidal activity and are able to control weeds or unwanted vegetation in a more efficient and effective manner.

The present invention relates firstly to a composition for controlling weeds or the growth of undesirable plants comprising a herbicide combination consisting of (i) L-glufosinate and/or agronomically acceptable salts thereof, and (ii) indaziflam, in which the components (i ) and (ii) are the only active ingredients in the composition where the weight ratio of the total amount of component (i) to the total amount of component (ii) is in the range from 15:1 to 30:1 in each case, based on the total weight of the composition, together with one or more excipients.

Preferably, the weight ratio of the total amount of component (i) to the total amount of component (ii) in the herbicide combination according to this invention is in the range from 15:1 to 25:1, and most preferably in the range from 18:1 to 24:1.

The herbicidal compositions comprising these herbicidal combinations according to the present invention exhibit very good herbicidal activity in controlling harmful plants or unwanted vegetation.

It has been found that the effectiveness of L-glufosinate and/or its agronomically acceptable salts

- 1 040926 can be improved by combining L-glufosinate and/or its agronomically acceptable salts with indaziflam in a weight ratio that is specified in the context of this invention.

The herbicidal composition comprising this herbicidal combination (its use), as defined in the context of this invention, shows a markedly higher/strong initial herbicidal activity (see aspect (d) above) than L-glufosinate and/or its agronomically acceptable salts when acting alone.

The herbicidal composition comprising this herbicidal combination (its use), as defined in the context of this invention, shows a markedly longer duration of herbicidal activity (see aspect (e) above) than L-glufosinate and/or its agronomically acceptable salts when exposed to by oneself. For example, this longer-lasting herbicidal activity results in a significant delay or significant delay in the regrowth of weeds or unwanted plants and/or in a significant delay or significant inhibition of the germination of weeds or unwanted plants.

The herbicidal composition comprising this herbicidal combination (use thereof), as defined in the context of this invention, has an overall faster onset (e.g., earlier and faster) and longer lasting herbicidal action compared to L-glufosinate alone and/or its agronomically acceptable salts. when applied to weeds or unwanted plants, parts of those weeds or unwanted plants, or to areas where these weeds or unwanted plants grow, such as cultivated areas, especially when applied post-emergence.

Thus, indaziflam (component (ii) as defined in the context of this invention) enhances, extends and/or prolongs the herbicidal activity of L-glufosinate and/or its agronomically acceptable salts (component (i) as defined in the context of this invention).

The herbicidal composition comprising this herbicidal combination (use thereof) as defined in the context of this invention also allows good selectivity and compatibility with (young) plantation crop plants (see aspect (c) above), thereby preventing or reducing undesirable hazard and/or undesirable reduction in yield of (young) plantation crops.

If a herbicidal composition comprising this herbicidal combination (its use), as defined in the context of this invention, is applied to the green parts of weeds or unwanted plants, their growth is abruptly stopped within a very short period of time after treatment; typically they die out completely after a certain period of time, so that weed competition, which is harmful (permanently) to crops, is thus eliminated quite early in time and in a long-term manner.

In addition, the herbicidal composition comprising this herbicidal combination (use thereof), as defined in the context of the present invention, allows very efficient and effective lateral shoot control on trees, and exhibits good and improved rain tolerance.

In addition, herbicide compositions comprising these herbicide combinations (used) in accordance with this invention can be used as plant growth regulators.

Preferably, this invention relates to a composition as defined herein in the context of this invention, which further comprises one or more other components selected from the group consisting of formulation auxiliaries, conventional crop protection additives, and other agrochemically active compounds (t i.e. agrochemically active compounds other than components (i) and (ii) as defined above, i.e. agrochemically active compounds other than (i) glufosinate and/or its agronomically acceptable salts, L-glufosinate and its agronomically acceptable salts and (ii) indaziflam).

In a preferred embodiment, the herbicide composition, as defined herein in the context of this invention, does not contain saflufenacil.

However, if the composition used in the context of this invention includes a combination of herbicides (i) L-glufosinate and/or its agronomically acceptable salts and (ii) indaziflam used in the context of this invention, this means that the herbicide composition should not contain any other (ie, no additional) herbicidally active ingredient, and preferably does not contain any other agrochemically active compound. Such herbicide combinations consisting of (i) L-glufosinate and/or agronomically acceptable salts thereof (L-glufosinate-ammonium is preferred) and (ii) indaziflam are particularly preferred in the context of this invention.

In this context, the terms other herbicidally active ingredient and other agrochemically active compound refer to herbicides and agrochemically active compounds (pesticides), respectively, as listed in The Pesticide Manual, 16th edition, The British Crop Protection Council and the Royal Soc. of Chemistry, 2012, which are different from glufosinate and its agronomically acceptable salts, L-glufosinate and its agronomically acceptable salts, and indaziflam.

In a preferred composition according to this invention, the total amount of component (i)

- 2 040926 is equal to or less than 600 g/l, preferably the total amount of component (i) is equal to or less than

450 g/l and more preferably the total amount of component (i) is equal to or less than 300 g/l, in each case, calculated on the total amount of the composition.

Preferably the total amount of component (i) in the composition according to the invention is in the range of 100 to 600 g/l, preferably in the range of 125 to 450 g/l, more preferably in the range of 125 to 300 g/l, most preferably in the range from 125 to 250 g/l, in each case based on the total amount of the composition.

In a preferred composition according to the invention, the total amount of component (ii) is in the range of 2 to 20 g/l, preferably in the range of 3 to 15 g/l, more preferably in the range of 3 to 12 g/l, even more preferably in in the range of 3 to 10 g/l, most preferably in the range of 3 to 6 g/l, in each case based on the total amount of the composition.

For example, a composition according to the present invention comprising a total of component (i) of about 150 g/l and a total of component (ii) of about 4 g/l, in each case based on the total amount of the composition, shows the benefits and effects described in the context of this invention.

However, our own experiments also show that if the ratio of the total amount of component (i) to the total amount of component (ii) in the herbicide combination according to this invention is significantly greater than 30:1, for example 50:1 (i.e. >50:1) , then the beneficial effects observed in the context of the present invention and mentioned above no longer reach the desired level in any way.

Therefore, the weight ratio of the total amount of component (i) to the total amount of component (ii) in the herbicidal combination according to the present invention is preferably within the preferred ranges mentioned above.

This invention preferably relates to the use of a composition comprising a combination of herbicides, as defined in the context of this invention, either on land planted with perennial crops or perennial crops.

As shown in the biological examples below, for example, the following weeds or unwanted plants are more effectively and better controlled by the compositions of this invention compared to L-glufosinate alone: Amaranthus retroflexus, Stellaria media, Lolium multiflorum and Poa annua.

If the herbicidal compositions according to the invention are applied after emergence on the green parts of the plants, then the growth stops abruptly within a very short period of time after the treatment and the weeds stop at the growth stage at the time of application, or they die completely after a certain time, so that thus eliminate weed competition that is detrimental to crop plants at a very early point in time and to a significant extent.

The herbicidal compositions of the present invention are characterized by rapid onset of action and long lasting herbicidal action. In general, the rain resistance of the active compounds in the herbicidal compositions of this invention is favorable. A particular advantage is that the dosage of herbicides (i) and (ii), as defined in the context of the present invention, can be adjusted to such a small amount that its effect on the soil is small. This also allows their use in sensitive agricultural crops (such as (young) crop plantations). In addition, the combination of herbicides (i) and (ii), as defined in the context of this invention, allows the application of the application amount of herbicides (i) and (ii), which can be reduced.

In particular, when herbicide compositions comprising herbicide combinations as defined in the context of this invention use application rates that can be reduced, a wider range of broadleaf weeds and grassy weeds can be controlled, herbicidal action can occur more quickly, duration of action can be longer. prolonged, weeds may be better controlled with only one or a few applications and extension of the application period is possible.

The properties and benefits mentioned above are useful for weed control practices in order to keep crops free from unwanted plant competition and thereby guarantee and/or increase yields from a qualitative and/or quantitative point of view. These new combinations markedly exceed the state of the art in terms of the properties described.

Because of their herbicidal properties and plant growth regulating properties, the compositions of this invention can be used to control weeds in genetically modified plant cultures or in crops obtained by mutation/selection. These crops are typically distinguished by particular, improved properties such as resistance to herbicidal compositions or resistance to plant diseases or causative agents of plant diseases such as certain insects or microorganisms such as fungi, bacteria or viruses. Other special properties relate, for example, to the crop material in terms of quality, quantity, shelf life, composition and specific constituents. Thus, for example, transgenic plants are known in which the starch content is increased or the quality of the starch has changed, or in which the crop material has an altered fatty acid composition.

The invention also relates to a method for controlling the growth of unwanted plants and/or controlling weeds which comprises the step of applying the above composition according to the invention to the unwanted plants or weeds, to parts of the unwanted plants or weeds or to an area in which the unwanted plants or weeds grow or weed plants. Preferably, the application is carried out post-emergence.

In the context of this invention, control means a significant reduction in the growth of weed(s) plant(s) compared to untreated weeds. Preferably the growth of the weed(s) plant(s) is significantly reduced (60-79%), more preferably the growth of the weed(s) plant(s) is significantly or completely suppressed (80-100%) and even more preferably the growth of the weed(s) (s) is almost completely or completely suppressed (90-100%).

Herbicidal preparations comprising glufosinate or its salts (such as ammonium glufosinate) are well known to those skilled in the art, for example from EP 0048436, EP 0336151 A2, US 5258358, US 5491125, US 2005/0266995 A1, US 2005/0266998 A1, US 2005 /266999 A1, US 2007/0184982 A1 or US 2008/0045415 A1, and such preparations are suitable in the context of this invention.

Preferably, the herbicidal compositions of this invention (preferably in one of the preferred embodiments defined herein) are in the form of suspension concentrates (SC), oil dispersions (OD) or microcapsules.

Preferably, the herbicidal compositions of this invention (preferably in one of the preferred embodiments defined herein) can be prepared easily and quickly by mixing components (i) and (ii) in such a weight ratio as defined in the context of this invention, for example, by mixing suitable amounts components (i) and (ii).

Thus, the present invention also relates to a process for preparing a composition according to the present invention, comprising the steps of:

(a) providing component (i), (b) providing component (ii), and (c) combining component (i) and component (ii) together with one or more excipients, so that a composition according to this invention is obtained.

The types of individual formulations are known in principle and are described, for example, in Winnacker-Kuchler, Chemische Technologie, Volume 7, C. Hauser Verlag Munich, ^4th Edition, 1986; van Valkenburg, Pesticide Formulations, Marcel Dekker NY, 1973; K. Martens, Spray Drying Handbook, 3rd Ed. 1979, G. Goodwin Ltd. London.

Required formulation auxiliaries such as inert materials, surfactants, solvents, and other additives are also known and described, for example, in Watkins, Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Darland Books, Caldwell NJ ; Hv Olphen, Introduction to Clay Colloid Chemistry; 2nd Ed., J. Wiley & Sons, NY Marsden, Solvents Guide, 2nd Ed., Interscience, NY 1950; McCutcheon's, Detergents and Emulsifiers Annual, MC Publ. Corp., Ridgewood NJ; Sisley and Wood, Encyclopedia of Surface Active Agents, Chem. Publ. Co. Inc., NY 1964; Schonfeldt, Grenzflachenaktive Athylenoxidaddukte [Surface-active ethylene oxide adducts], Wiss. Verlagsgesellschaft, Stuttgart 1976, Winnacker-Kuchler, Chemische Technologie, Volume 7, C. Hauser Verlag Munich, ^4th Edition 1986.

Based on these preparations, compositions can also be prepared with other agrochemically active substances, such as other herbicides not related to constituent components (i) and (ii), as defined in the context of this invention, fungicides or insecticides, and with protective substances, fertilizers and/or plant growth regulators, for example, in the form of ready-made mixtures or mixtures prepared in large tanks.

Wettable powders (sprayable powders) are products which are uniformly dispersed in water and which, in addition to the active compound, also contain ionic or non-ionic surfactants (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyethoxylated fatty alcohols or fatty amines, alkane sulfonates or alkylbenzenesulfonates, sodium lignosulfonates, sodium 2,2'-dinaphthylmethane-6,6'-disulfonates, sodium dibutylnaphthalenesulfonates or also sodium oleoylmethyltaurides, in addition to a diluent or inert material.

Emulsifiable concentrates are obtained by dissolving the active compound in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene, or also in high-boiling aromatic compounds or hydrocarbons, with the addition of one or more ionic or

- 8 040926 non-ionic surfactants (emulsifiers). Examples of emulsifiers that can be used include calcium salts of alkylarylsulfonic acids, such as calcium dodecylbenzenesulfonate, or non-ionic emulsifiers, such as polyglycol fatty acid esters, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, esters. fatty acid sorbitan, polyoxyethylene sorbitan fatty acid esters or polyoxyethylene sorbitol esters.

Dust-like preparations are obtained by grinding the active compound with a fine solid material, for example talc, natural clays such as kaolin, bentonite and pyrphyllite or diatomaceous earth.

Suspension concentrates (SC) can be water or oil based. They can be obtained, for example, by wet grinding using commercially available ball mills and, if necessary, with the addition of other surfactants, such as those mentioned above in the case of other types of drugs.

Emulsions, e.g. oil-in-water (EO) emulsions, can be prepared, for example, with agitators, colloid mills and/or static agitators using aqueous organic solvents and, if necessary, other surfactants, as has already been mentioned, for example, above in the case of other types of preparations.

Granules can be prepared either by spraying the active compound onto an adsorbent, granular inert material, or by applying active compound concentrates to the surface of carriers such as sand, kaolinites or granular materials using binders such as, for example, polyvinyl alcohol, sodium polyacrylate or also mineral oils. Suitable active compounds can also be granulated in the manner normally used in the preparation of granular fertilizers, if desired mixed with the fertilizers. Generally, water-dispersible granules are produced by conventional methods such as spray drying, fluidized bed granulation, disk granulation, high-speed agitation, and extrusion without solid inert material. With respect to the preparation of disc granules, fluidized bed granules, extrusion granules, and spray granules, see, for example, the methods in the Spray-Drying Handbook 3rd ed. 1979, G. Goodwin Ltd., London; J.E. Browning, Agglomeration, Chemical and Engineering 1967, p. 147 et seq; Perry's Chemical Engineer's Handbook, 5th Ed., McGraw-Hill, New York 1973, pp. 8-57.

For further details regarding the formulation of crop protection products, see, for example, G.C. Klingmam, Weed Control as a Science, John Wiley and Sons, Inc., New York, 1961, pp. 81-96 and J.D. Freyer, S.A. Evans, Weed Control Handbook, 5th Ed., Blackwell Scientific Publications, Oxford, 1968, pp. 101-103.

As a rule, agrochemical preparations contain from 1 to 95% by weight of the active compound, the following concentrations are typical depending on the type of preparation.

The concentration of the active compound in wettable powders is, for example, approximately 10-95 wt.%, the rest, remaining up to 100 wt.%, is composed of the usual auxiliary components of the preparations. In the case of emulsion concentrates, the concentration of the active compound may be, for example, from 5 to 80% by weight. Dust preparations contain in most cases from 5 to 20% by weight of the active compound, spray solutions contain approximately 0.2-25% by weight of the active compound. In the case of granules, such as dispersible granules, the content of the active compound depends in part on whether the active compound is present in liquid or solid form and on which granulation aids have been used. As a rule, the amounts contained are between 10 and 90% by weight in the case of water-dispersible granules.

In addition, the active compound preparations mentioned above may include, if necessary, conventional binders, wetting agents, dispersing agents, emulsifiers, preservatives, antifreeze agents, solvents, fillers, colorants, carriers, defoamers, evaporation inhibitors, pH adjusters or viscosity adjusters.

The herbicidal action of the herbicidal composition according to the invention can be improved, for example, by using surfactants, preferably wetting agents from the group of fatty alcohol ethers with polyglycols. The fatty alcohol ethers with polyglycols preferably contain 10-18 carbon atoms in the fatty alcohol radical and 2-20 ethylene oxide units in the polyglycol ether unit. The ethers of fatty alcohols with polyglycols can be non-ionic or ionic, for example, in the form of fatty alcohol ether sulfates with polyglycols, which can be used, for example, in the form of alkali metal salts (for example, sodium salt or potassium salt) or ammonium salt, and also in the form of alkaline earth metal salts, such as a magnesium salt, such as sodium sulfate of a C ₁₂ /C ₁₄ fatty alcohol ether with diglycol (Genapol® LRO, Clariant); see, for example, EP-A-0476555, EP-A-0048436, EP-A-0336151 or US-A-4400196 and also Proc. EWRS Symp. Factors Affecting Herbicidal Activity and Selectivity, 227-232 (1988). Nonionic ethers of fatty alcohols with polyglycols are, for example, ethers of (C ₁₀ -C ₁₈ )-, preferably (C ₁₀ -C ₁₄ )-fatty alcohols with polyglycol containing 2-20, preferably 3-15 ethylene oxide units (for example, a simple ether of isotridecyl alcohol with polyglycol), for example, from the Genapol® series, such as Genapol® X-030,

Genapol® X-060, Genapol® X-080 or Genapol® X-150 (all from Clariant GmbH).

The invention further encompasses combinations of herbicides (i) and (ii) as defined above with wetting agents as mentioned above from the group of fatty alcohol ethers with polyglycols which contain 10-18 carbon atoms in the fatty alcohol radical and 2 -20 ethylene oxide units per polyglycol ether unit, and which may be present in non-ionic or ionic form (eg as fatty alcohol ether sulfates with polyglycols). Preference is given to sodium sulfate of C ₁₂ /C ₁₄ fatty alcohol ether with diglycol (Genapol® LRO, Clariant) and isotridecyl alcohol ether with polyglycol with 3-15 ethylene oxide units, for example from the Genapol® X series, such as Genapol® X-030, Genapol® X060, Genapol® X-080 or Genapol® X-150 (all from Clariant GmbH). In addition, fatty alcohol ethers of polyglycols, such as non-ionic or ionic fatty alcohol ethers of polyglycols (e.g. fatty alcohol ether sulfates of polyglycols) are also known to be suitable for use as penetration enhancers or activity enhancers for a number of other herbicides, inter alia, for herbicides from the group of imidazolinones (see, for example, EP-A-0502014).

Moreover, fatty alcohol polyglycol ethers such as nonionic or ionic fatty alcohol polyglycol ethers (e.g. fatty alcohol polyglycol ether sulfates) are also known to be useful as penetration enhancers and synergists for a number of other herbicides. , inter alia, for herbicides from the group of imidazolinones (see, for example, EP-A-0502014).

The herbicidal effect of the herbicidal compositions according to the invention can also be enhanced by using vegetable oils. The term vegetable oils should be understood as oils obtained from oil-bearing plant species, such as soybean oil, rapeseed oil, corn oil, sunflower oil, cottonseed oil, linseed oil, coconut oil, palm oil, safflower oil or castor oil, more preferably rapeseed oil and their transesterification products, for example alkyl esters such as methyl ester or ethyl ester of rapeseed oil.

Vegetable oils are preferably esters of (Ci-C ₂₂ )-, more preferably (C ₁₂ -C ₂₀ )-fatty acids. Esters of (C ₁₀ -C ₂₂ )-fatty acids are, for example, esters of unsaturated or saturated (C ₁₀ -C ₂₂ )-fatty acids, in particular those with an even number of carbon atoms, such as erucic acid, lauric acid, palmitic acid , and in particular C ₁₈ fatty acids such as stearic acid, oleic acid, linoleic acid or linolenic acid.

Preferred (C ₁ -C ₂₀ )-alkyl esters of (C ₁₀ -C ₂₂ )-fatty acids are methyl, ethyl, propyl, butyl, 2-ethylhexyl and dodecyl esters. Preferred glycol and glycerol esters of (C ₁₀ -C ₂₂ )-fatty acids are single or mixed glycol esters and glycerol esters of (C ₁₀ -C ₂₂ ) fatty acids, especially those with an even number of carbon atoms, such as erucic acid, lauric acid, palmitic acid, and in particular C ₁₈ fatty acids such as stearic acid, oleic acid, linoleic acid or linolenic acid.

Vegetable oils may be present in the herbicidal compositions of this invention, for example, as commercially available oil-containing formulation additives, in particular those based on rapeseed oil, such as Hasten® (Victorian Chemical Company, Australia, hereinafter referred to as Hasten, main ingredient: rapeseed oil ethyl ester), Actirob®B (Novance, France, hereinafter referred to as ActirobB, main ingredient: rapeseed oil methyl ester), Raco-Binol® (Bayer AG, Germany, here hereinafter referred to as Rako-Binol, main component: rapeseed oil), Renol® (Stefes, Germany, hereinafter referred to as Renol, contained vegetable oil component: rapeseed oil methyl ester), or Stefes Mero® (Stefes, Germany, here hereinafter referred to as Mero, main constituent: rapeseed oil methyl ester).

In another embodiment, this invention may cover the composition of the herbicidal combination, as defined in the context of this invention, with the vegetable oils mentioned above. Thus, in another embodiment, this invention may cover the use of compositions comprising herbicidal combinations, as defined in the context of this invention, comprising the vegetable oils mentioned above, such as rapeseed oil, preferably in the form of commercially available oil-containing formulation additives, in particular those based on rapeseed oil, such as Hasten® (Victorian Chemical Company, Australia, hereinafter referred to as Hasten, main constituent: rapeseed oil ethyl ester), Actirob®B (Novance, France, hereinafter referred to as ActirobB, main component: methyl ester of rapeseed oil), Rako-Binol® (Bayer AG, Germany, called Rako-Binol here below, main component: rapeseed oil), Renol® (Stefes, Germany, called

Renol here below, ingredient from vegetable oil: rapeseed oil methyl ester) or Stefes Mero® (Stefes, Germany, here below called Mero, main ingredient: rapeseed oil methyl ester).

For use, formulations which are presented in commercially available form are diluted if necessary in the usual manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersible and water-dispersible granules. Powdered formulations, soil granules, scatter granules and spray solutions are generally not further diluted with other inert substances prior to use.

The herbicidal composition comprising the herbicidal combination as defined in the context of the present invention is preferably applied to weeds or unwanted plants or parts thereof, to plant seeds or cultivated areas (field soil), preferably to weed greens or parts thereof. or on the greens of undesirable plants or their parts.

A composition comprising a herbicidal combination in the context of the present invention has the advantage of being easier to apply since the quantities of the components are already present in the correct ratio to each other. In addition, excipients in the preparation can be optimally matched to each other.

As already described in more detail above, this invention further relates to the use of the composition according to this invention for the control of weeds and/or the growth of unwanted plants.

Examples

1. Used (chemical) products.

The following (chemical) products were used for the biological tests described below:

product P1 containing L-glufosinate (i.e., enantiomerically pure) not in accordance with this invention, product P2 containing L-glufosinate (i.e., enantiomerically pure) and indaziflam [weight ratio (1* R)-1-fluoroethyl diastereoisomer of indaziflam to weight of (1*S)-1-fluoroethyl diastereoisomer of indaziflam was about 95:5], while the weight ratio of total L-glufosinate to total indaziflam was 18.75:1, product P3 containing L-glufosinate (i.e. in enantiomerically pure form) and indaziflam [the ratio of the weight of (1*R)-1-fluoroethyl diastereoisomer of indaziflam to the weight of (1*S)-1-fluoroethyl diastereoisomer of indaziflam was about 95:5] , in which the weight ratio of the total amount of L-glufosinate to the total amount of indaziflam was 37.5:1.

Indaziflam is known to show insufficient post-emergence efficacy on monocot and dicotyledonous weed species. Accordingly, a product containing 4 g/l of indaziflam [the ratio of the weight of (1*R)-1-fluoroethyl diastereoisomer of indaziflam to the weight of (1*S)-1-fluoroethyl diastereoisomer of indaziflam was about 95:5], used with a consumption dose of 12 g /ha showed only very limited post-emergence efficacy against monocot and dicot weeds.

2. Biological tests.

Biological tests were carried out in separate pots in a greenhouse under identical conditions (separate from treatment with the various P1, P2 and P3 products mentioned above). Each pot contained the same soil and the same number of seeds from each of the following weeds (two monocots and two dicots (weed species)):
