Description

[0001]231380 1 Herbicide compositions comprising a malonamide compound and a glutamine synthase inhibitor for effective weed control. The present invention relates to a method for weed control, which comprises applying an effective amount of a herbicidal malonamide (Component A) and a glutamine synthase inhibitor (Component B) to a non-crop area or to the cultivation area of a crop, where weeds grow or may grow, as described herein. The present invention also relates to a composition comprising a herbicidal malonamide (Component A) and a glutamine synthase inhibitor (Component B) and its use for weed control in a non-crop area or in the cultivation area of a crop. BACKGROUND ON THE INVENTION Weed control is a critical and pressing concern in agricultural practice, impacting crop productivity and overall agricultural sustainability. Weeds compete with crops for essential resources such as water, nutrients, and sunlight. Their rapid growth and aggressive nature can significantly reduce crop yields if not adequately controlled. Over time, weeds can develop resistance to herbicides, making them less susceptible to chemical control methods. This can render certain herbicides ineffective and limit the options available for weed management. In addition, different weed species often coexist in agricultural fields, and a herbicidal composition that provides broad-spectrum control against multiple weed species is highly desirable. Ensuring effective control of diverse weeds can be a significant challenge. Addressing these challenges requires innovative solutions and continuous research and development efforts to enhance weed control strategies while minimizing their impact on the environment and crop productivity. WO2021 / 170464 discloses certain malonamide compounds and compositions comprising the same for controlling unwanted vegetation. While these malonamide compounds show excellent herbicidal activity as well as certain selectivity in crops, there remains a need for methods to control heterogeneous weed species. We have found that this object and further objects are achieved by a composition comprising A) a herbicidal malonamide selected from a of formula , wherein 231380 2 R1, R2and R3are each independently hydrogen, halogen, cyano, (C1-C3)-alkyl, (C1-C3)-haloalkyl, (C1-C3)-alkoxy or (C1-C3)-haloalkoxy; and R4is hydrogen or (C1-C6)-alkyl, (C2-C4)-alkenyl, (C3-C4)-alkynyl, (C3-C6)-cycloalkyl, (C3-C6)-cycloalkyl-(C1-C3)- alkyl, phenyl-(C1-C3)-alkyl or furanyl-(C1-C3)-alkyl, where each of the seven last-mentioned radicals is substituted by m radicals selected from the group consisting of fluorine, chlorine, bromine, cyano, CO2Ra, CONRbRc, (C1-C2)-alkoxy, (C1-C3)-alkylthio, (C1-C3)-alkylsulfinyl, (C1-C3)-alkylsulfonyl, phenylthio, phenylsulfinyl, and phenylsulfonyl; each Rais independently (C1-C6)-alkyl, (C2-C4)-alkynyl or (C3-C6)-cycloalkyl, each of which is substituted by m radicals selected from the group consisting of fluorine, chlorine, bromine, iodine, cyano, hydroxy, and (C1- C3)-alkoxy; Rbis hydrogen or has one of the meanings given for Ra; Rcis hydrogen or (C1-C6)-alkyl, (C1-C2)-alkoxy, (C3-C6)-cycloalkyl, (C2-C4)-alkenyl, (C1-C6)-alkoxycarbonyl-(C1- C6)-alkyl, or (C3-C4)-alkynyl, where each of the six last-mentioned radicals is substituted by m radicals selected from the group consisting of fluorine, chlorine, bromine, cyano, CO2Ra, and (C1-C2)-alkoxy; each m is independently 0, 1, 2, 3, 4 or 5; including their agriculturally acceptable salts, stereoisomers and tautomers; and B) a glutamine synthase inhibitor (Component B) selected from bilanaphos (bialaphos), bilanaphos-sodium, glufosinate, glufosinate-ammonium, glufosinate-P, glufosinate-P-sodium, and glufosinate-P-ammonium. SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for weed control in non-crop areas or in cultivation areas of a crop, which allows control of the weeds which grow or may grow in these areas. In addition, the method should provide weed control over an adequately long period, thus allowing flexible application. Surprisingly, it has now been found that weeds that grow or will grow in a non-crop area or in a cultivation area of crops are controlled by applying to these areas an effective amount of a combination of A) a herbicidal malonamide A), selected from a of formula (I) wherein R1, R2and R3are each independently hydrogen, halogen, cyano, (C1-C3)-alkyl, (C1-C3)-haloalkyl, (C1-C3)-alkoxy or (C1-C3)-haloalkoxy; and 231380 3 R4is hydrogen or (C1-C6)-alkyl, (C2-C4)-alkenyl, (C3-C4)-alkynyl, (C3-C6)-cycloalkyl, (C3-C6)-cycloalkyl-(C1-C3)- alkyl, phenyl-(C1-C3)-alkyl or furanyl-(C1-C3)-alkyl, where each of the seven last-mentioned radicals is substituted by m radicals selected from the group consisting of fluorine, chlorine, bromine, cyano, CO2Ra, CONRbRc, (C1-C2)-alkoxy, (C1-C3)-alkylthio, (C1-C3)-alkylsulfinyl, (C1-C3)-alkylsulfonyl, phenylthio, phenylsulfinyl, and phenylsulfonyl; each Rais independently (C1-C6)-alkyl, (C2-C4)-alkynyl or (C3-C6)-cycloalkyl, each of which is substituted by m radicals selected from the group consisting of fluorine, chlorine, bromine, iodine, cyano, hydroxy, and (C1- C3)-alkoxy; Rbis hydrogen or has one of the meanings given for Ra; Rcis hydrogen or (C1-C6)-alkyl, (C1-C2)-alkoxy, (C3-C6)-cycloalkyl, (C2-C4)-alkenyl, (C1-C6)-alkoxycarbonyl-(C1- C6)-alkyl, or (C3-C4)-alkynyl, where each of the six last-mentioned radicals is substituted by m radicals selected from the group consisting of fluorine, chlorine, bromine, cyano, CO2Ra, and (C1-C2)-alkoxy; each m is independently 0, 1, 2, 3, 4 or 5; including their agriculturally acceptable salts, stereoisomers, and tautomers; and B) a glutamine synthase inhibitor (Component B) selected from bilanaphos (bialaphos), bilanaphos-sodium, glufosinate, glufosinate-ammonium, glufosinate-P, glufosinate-P-sodium, and glufosinate-P-ammonium. The combination of Components A and B and compositions comprising Components A and B are suitable as herbicides. They are suitable as such or appropriately formulated (agrochemical composition). In the methods according to the present invention, the required application rate of the herbicidal malonamide (Component A), depends on the density of the undesired vegetation, on the development stage of the plants, on the climatic conditions of the location where the combination or composition of Components A and B is used and on the application method. In general, the application rate of the herbicidal malonamide (Component A), is from 1 to 500 g / ha, preferably from 1 to 250 g / ha, more preferably from 2 to 100 g / ha of active substance. In the methods according to the present invention, the required application rate of the glutamine synthase inhibitor (Component B), depends on the density of the undesired vegetation, on the development stage of the plants, on the climatic conditions of the location where the combination or composition of Components A and B is used and on the application method. In general, the application rate of the glutamine synthase inhibitor (Component B), is from 1 to 2000 g / ha, preferably from 2 to 1500 g / ha, more preferably from 3 to 1000 g / ha of active substance. The combination of Components A and B or the compositions comprising the herbicidal malonamide (Component A) and the glutamine synthase inhibitor (Component B), can generally be applied to weeds at any growth stage with good results. In one embodiment, the combination of Components A and B or the compositions comprising the herbicidal malonamide (Component A) and the glutamine synthase inhibitor (Component B), are applied up to BBCH growth stage 37 of the weeds. 231380 4 Weeds, which are controlled by the method according to the present invention include monocots and dicots. The present invention relates to a method for controlling weeds in crops, including cereals, maize, soybean, cotton, canola, sorghum and rice. In the method according to the present invention for controlling weeds in crops, the combination of Components A and B and the compositions comprising the herbicidal malonamide (Component A) and the glutamine synthase inhibitor (Component B) can generally be applied for pre-plant burn-down, as pre-emergence treatment of the crop, or as post-emergence treatment of a glutamine synthase inhibitor tolerant crop. Additionally, the combination of Components A and B and the compositions comprising the herbicidal malonamide (Component A) and the glutamine synthase inhibitor (Component B) can be applied as post-emergence treatment of a crop for pre-harvest desiccation. BBCH growth stages are as defined in “Growth stages of mono- and dicotyledonous plants”, BBCH Monograph edited by Uwe Meier Julius Kühn-Institut (JKI), Open Agrar Repositorium, Quedlinburg 2018 DOI: 10.5073 / 20180906-074619 ISBN: 978-3-95547-071-5. The method of the present invention for controlling weeds has several advantages over methods applying individual Components A or B or other herbicidal combinations: - The herbicide combinations of the present invention show enhanced herbicide action (efficacy) in comparison with solo application of the individual herbicides. Surprisingly, herbicide combinations of the present invention show an over-additive or synergistic effect in weed control in comparison with solo application of the individual herbicides. - Through their enhanced herbicide action, the herbicide combinations of the present invention can be applied at lower rates to achieve the desired herbicidal effect, reducing the potential negative impact on the environment, including soil and water quality, beneficial organisms, and non-target plants. - The herbicide combinations of the present invention show an increased spectrum of weed control in comparison with solo application of the individual herbicides. - The herbicide combinations of the present invention reduce the likelihood of resistance development in comparison with solo application of the individual herbicides. - The herbicide combinations of the present invention may provide more effective control of herbicide resistant weeds in comparison with solo application of the individual herbicides. In general, losses of efficacy (due to resistance development) in individual plants may be compensated to a limited extent by higher application rates of herbicides, with the potential side effect of increased crop damage (reduced selectivity). The herbicide combinations of the present invention achieve control of resistant weeds while maintaining a low crop response, especially in monocotyledonous crops. 231380 5 - The herbicide combinations of the present invention may also show an accelerated action on weeds, i.e. they may affect damage of the harmful plants more quickly in comparison with solo application of the individual herbicides. - The herbicide combinations of the invention provide for an adequate duration of herbicidal activity, even under difficult weathering conditions, which allows a more flexible application and minimizes the risk of weeds escaping. Further embodiments of the invention are evident from the description, the examples and the claims. It is to be understood that the features mentioned above and still to be illustrated below of the subject matter of the invention can be applied not only in the combination given in each particular case but also in other combinations, without leaving the scope of the invention. DETAILED DESCRIPTION OF THE INVENTION As used herein, the terms "controlling" and "combating" are synonyms, referring to inhibition of growth, control of growth, reduction of growth or complete destruction of weeds. As used herein, the term “combination” refers to any combination of Components A and B, including compositions comprising Components A and B. In the context of the present invention, it is immaterial whether the herbicidal malonamide (Component A) and the glutamine synthase inhibitor (Component B) are formulated separately or jointly. It is also immaterial, whether the herbicidal malonamide (Component A) and the glutamine synthase inhibitor (Component B) are 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 Components A and B of the combination or composition, the herbicidal malonamide and the glutamine synthase inhibitor are applied in an effective amount and in a time frame that allows simultaneous action of the Components on the plants, preferably within a timeframe of at most 14 days, in particular at most 7 days, very particular at most 1 day. As used herein, the term “composition” refers to compositions or mixtures comprising a herbicidal malonamide A and a glutamine synthase inhibitor B. Different salts of the herbicidal malonamide are considered as the same herbicide compound. As used herein, the term “agrochemical composition” refers to compositions or mixtures comprising a herbicidal malonamide A, a glutamine synthase inhibitor B, and one or more auxiliaries customary for herbicidal products or crop protection compositions. As used herein "herbicide" refers to one or more agents, compounds and / or compositions having herbistatic and / or herbicidal activity. 231380 6 As used herein, the terms "undesirable vegetation", "undesirable species", "undesirable plants", "harmful plants", "undesirable weeds", “volunteer plants”, “weeds” or "harmful weeds" are used synonymously. As used herein, the term "an effective amount" refers to the quantity or application rate of the Components A and B that is necessary to achieve the desired effect or result. It is the amount of the Components A and B that is sufficient to effectively control or eliminate the target weeds or plants, while minimizing any adverse effects on non-target organisms or the environment. The specific effective amount may vary depending on factors such as target plant species, application method, environmental conditions, and the desired level of control. Synergism can be determined by the Colby method (Colby, S.R., Weeds, 1967(15), p.20-22), i.e. the expected (or predicted) response of the combination is calculated by taking the product of the observed response for each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of the observed response for each component when applied alone. Synergism of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed responses of each individual component alone. If the observed response of the combination is significantly greater than the expected (or predicted) response as determined by Fisher's protected Least Significant Difference (LSD) test using significance level 0.05, than the combination is said to be synergistic. The foregoing is illustrated mathematically as follows: Expected response Exp.and Synergism Obs. Exp. LSD,wherein a combination is composed of components X and Y, and Obs. designates the observed response of this combination. The synergistic effect may also be given as the ratio of the observed response and the expected response in percent, i.e. synergistic effect [%] = Obs. / Exp. x 100 As used herein, “pre-plant burn-down” refers to the practice of applying a herbicide to a field or area before planting crops. The purpose of pre-plant burn-down is to control or eliminate existing weeds or vegetation to create a weed- free environment for the crops. Pre-plant burn-down can also help to prevent the development of herbicide-resistant weeds, as it reduces the overall weed seed bank in the soil. As used herein, “pre-emergence” refers to an herbicide treatment that is applied to an area before the crop has emerged from the ground or growing medium. 231380 7 As used herein, “post-emergence” refers to an herbicide treatment that is applied to an area after the crop has germinated and emerged from the ground or growing medium. As used herein “pre-harvest desiccation” refers to a method of drying or killing crops intentionally before harvest at a specific stage of crop development, typically when the crop has reached physiological maturity but is not yet fully dried, to promote uniform ripening and to facilitate the harvesting process.

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 231380 30 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.

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- ØØ41Ø-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 32 (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 combinations or compositions comprising a herbicidal malonamide as Component A and a glutamine synthase inhibitor as Component B can be applied in conventional manner by using techniques a 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, it should ensure the finest possible distribution of the active ingredients. If the combinations or compositions comprising a herbicidal malonamide as Component A and a glutamine synthase inhibitor as Component B is less well tolerated by certain crop plants, application techniques may be used in which the herbicidal composition is sprayed, with the aid of the spray apparatus, in such a way that they come into as little contact, if any, as possible with the leaves of the sensitive crop plants while reaching the leaves of undesirable plants which grow underneath, or the bare soil (post-directed, lay-by). The combinations or compositions comprising a herbicidal malonamide as Component A and a glutamine synthase inhibitor as Component B is applied to an area mainly by spraying, in particular foliar spraying of an aqueous dilution of the active ingredient of the composition. 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 l / ha or 50 to 1000 l / ha, for example from 100 to 500 l / ha. Application of the herbicidal combinations or compositions by the low-volume and the ultra-low- volume method is possible, as is their application in the form of microgranules. The combinations or compositions of the invention may also be applied in combination with, or by utilizing smart agricultural technologies, such as precision agriculture, remote and proximate imaging and image recognition, or smart agricultural site management programs. These smart agricultural technologies typically include models, e.g. computer programs, that support the user by considering information from a wide variety of sources to increase the quality and yield of harvested material, reduce damage by pests including the prediction of pest pressure and smart application of crop protection products, secure environmental protection, support quick and reliable agronomic decision making, reduce usage of fertilizers and crop protection products, reduce product residues in consumables increase spatial and temporal precision of agronomical measures, automate processes, and enable traceability of measures. Commercially available systems which include agronomic models are e.g. FieldScripts™ from The Climate Corporation, Xarvio™ from BASF, AGLogic™ from John Deere, etc. Information input for these models include but is not limited to soil data (e.g. pH, organic matter content, moisture level, nutrient content such as nitrogen, potassium, phosphorous and micronutrient content); information on the plants that are currently growing or that may grow at the area of interest including crop plants and / or weeds (e.g. type of plant, chlorophyl levels, biomass, growth stage, plant health, plant water status, plant growth models, genetic traits, biotic damage by infestation or infection with pests, abiotic damage as caused by drought or nutrient stress etc.); weather information (e.g. information on past and present, and forecast of future temperature, humidity, and / or precipitation); information on the location of the area and directly derivable information thereof (e.g. terrain features like altitude, slope, water bodies, sun exposure and hours of sunshine per day, vegetation period, etc.); information on pest pressure (e.g. information of the past or present occurrence of unwanted vegetation, fungal diseases and invertebrate pests at the area of interest, at neighboring areas, the region, or the vegetation zone); information on beneficial organisms (e.g. information of the past or present occurrence of beneficial organisms at the area of interest, at neighboring areas, the region, or the vegetation zone); and / or historic information of any of the aforementioned (e.g. information on previous seasons, or of an earlier point in time of the same season). The information usable for precision agriculture may be based on input by at least one user, be accessible from external data sources and databases, or be based on sensor data. Data sources typically include proximate- detection systems like soil-borne sensors and remote sensing as may be achieved by imaging with unmanned airborne vehicles like drones, or satellites. Imaging technologies includes poly- and multispectral imagery in the UV- VIS, NIR and UV spectrum. Sensors may be included in an Internet-of-Things system and may be directly or indirectly connected to the processing unit, e.g. via a wireless network and / or cloud applications. The information is typically taken into account by at least one processing unit and used to provide recommendations, generate control signals (e.g. for the control of agricultural machinery like tractors, drones, irrigation systems, farm management systems and the like), and / or generate (digital) maps on the area of interest. These (digital) maps contain spatially and optionally temporally resolved information of the agricultural site, wherein the information may contain information directly gathered as described above, combinations thereof or derived thereof, such as pest pressure, 39 nutrient levels, and the like. The recommendations, control signals and (digital) maps may relate to or be used for controlling the application of water, nutrients, agrochemical products, or plant propagation material to the field of interest, or for taking other management measures like tilling, physical or laser-induced weeding. Typical technologies that are used in smart agricultural technologies include self-steering robots (such as tractors, harvesters, drones), artificial intelligence (e.g. machine learning), imaging technologies (e.g. image segmentation technologies), big data analysis, and model generation, cloud computing, and machine-to-machine communication. Precision agriculture such as precision farming is characterized by spatially and / or temporally resolved, targeted application of active ingredients like pesticides, preferably the compositions according to the present invention, plant- growth-regulators, fertilizers, and / or water including the variation of application rates over the agronomic site, zone or spot application, and of the spatially and / or temporally resolved, targeted planting or seeding of desired plant propagation material to a agronomic site. Precision farming typically includes the use of geo-positioning technologies like GPS for gaining information on the location and boundaries of the area of interest, the utilized application equipment, sensing equipment and recorded data, and to control the actions of farm vehicles such as spraying. By combining geo-positioning data with (digital) maps, it is possible to (semi)-automate agricultural measures at the site of interest, e.g. by using (semi)-autonomous spraying or seeding equipment. Precision farming may typically include the application of smart spraying equipment, e.g. spot spraying, and precision spraying at a farm, e.g. by irrigation systems, tractors, robots, helicopters, airplanes, unmanned aerial vehicles, such as drones. Such equipment usually includes input sensors (such as e.g. a camera) and a processing unit configured to analyze the input data and configured to provide a recommendation or decision based on the analysis of the input data to apply the compositions of the invention to the agronomic site, e.g. the soil or to control pests in a specific and precise manner. For example, weeds may be detected, identified, and / or classified from imagery acquired by a camera. Such identification and / classification can make use of image processing algorithms, which may utilize artificial intelligence (e.g. machine learning algorithms), or decision trees. In this manner, the combinations or compositions described herein can be applied at the required location, point in time and dose rate.

To prepare emulsions, pastes or oil dispersions, the active components, as such or dissolved in an oil or solvent, can be homogenized in water by means of wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates consisting of active substance, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, and these concentrates are suitable for dilution with water. Powders, materials for spreading and dusts can be prepared by mixing or concomitant grinding of the active the herbicides A and B with a solid carrier. Granules, e.g. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. The formulations comprise a herbicidally effective amount of the binary herbicide combination of the herbicide A and B. The concentrations of the active ingredients in the formulations can be varied within wide ranges. In general, the 231380 42 formulations comprise from 1 to 98% by weight, preferably 10 to 60 % by weight, of active ingredients (sum of the herbicide A and B, and optionally further actives). The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

Other additives such as non-phytotoxic oils and oil concentrates may also be added. Use Examples The herbicidal activity of the combinations and compositions comprising a herbicidal malonamide as Component A and a glutamine synthase inhibitor as Component B was demonstrated by the following greenhouse experiments: The culture containers used were plastic flowerpots containing loamy sand with approximately 3.0% of organic matter as the substrate. The seeds of the test plants were sown separately for each species. For the post-emergence treatment, the test plants were first grown to a height of 2 to 25 cm, depending on the plant habit, and only then treated with the Components A and B, which had been suspended or emulsified in water. For this purpose, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment. 231380 44 Depending on the species, the test plants were kept at 10 – 25°C or 20 – 35°C, respectively. The test period extended over 2 to 4 weeks. During this time, the test plants were tended, and their response to the individual treatments was evaluated. Evaluation was carried out using a scale from 0 to 100.100 means complete destruction of at least the aerial moieties, and 0 means no damage, or normal course of growth. A good herbicidal activity is given at values of 80 to 90 and a very good herbicidal activity is given at values of 90 to 100. The test plants used in the greenhouse experiments were of the following species: EPPO Code Scientific name ABUTH Abutilon theophrasti APESV Apera spica-venti AVEFA Avena fatua CHEAL Chenopodium album ECHCG Echinochloa crus-galli GALAP Galium aparine MATIN Matricaria inodora POAAN Poa annua SINAR Sinapis arvensis VERPE Veronica persica Dash® is an EC-formulated adjuvant containing oil acid (46.5 g / L), methyl ester of fatty acid (348.75 g / L) and fatty alcoholates (209.25 g / L). Colby's formula was applied to determine whether the composition showed synergistic action. The value E, which is to be expected if the activity of the individual compounds is just additive, was calculated using the method of S. R. Colby (1967) “Calculating synergistic and antagonistic responses of herbicide combinations“, Weeds 15, p.22 ff. For two component mixtures the value E was calculated by the following formula E = X + Y – (X.Y / 100) where X = effect in percent using herbicide A at an application rate a; Y = effect in percent using herbicide B at an application rate b; E = expected effect (in %) of A + B at application rates a + b. If the value observed in this manner is higher than the value E calculated according to Colby, a synergistic effect is present. Synergism is the ratio observed effect to the expected effect E in %. 231380 45 The invention is elucidated in more detail by the examples hereinafter. Example 1: Component A: I.a.1 was used as 5 % EC formulation with 0.5% of DASH®. Component B: Glufosinate-P ammonium (L-GA, L-Glufosinate ammonium) was used as soluble liquid (SL) with 211 g / L loading, with 0.5% DASH®.
