Accordingly, the term "in synergistically effective amounts" means that the amount of the mixture applied according to the invention is suitable for enhancing the health of a plant in a synergistic manner.

[060] The term "plant health" or "plant health" is defined as a condition of the plant and / or its products that is determined by various aspects alone or in combination with each other, such as yield, vigor of the plant. plant quality and tolerance to abiotic and / or biotic stress.

[061] The indicators identified below for the health of a plant may be interdependent or may result from each other. Each is considered as an individual embodiment of the present invention.

[062] An indicator for plant condition is yield. “Yield” shall be understood to mean any plant product of economic value that is produced by the plant, such as grains, fruits in the proper sense, vegetables, nuts, grains, seeds, wood (eg in the case of forestry plants) or even flowers (eg in the case of gardening plants, ornamental plants).

In accordance with the present invention, the yield is increased by at least 4%, preferably by 5 to 10%, more preferably by 10 to 20%, or up to 20 to 30%. In general, the yield increase may be even greater.

[068] Another indicator for plant condition is plant vigor. The vigor of the plant becomes evident in many aspects, such as the overall visual appearance.

[069] Optimized plant vigor can be characterized, among others, by the following improved plant properties: • improved plant vitality • improved plant growth • improved plant development • improved visual appearance • improved plant toughness (plant resort • improved emergence • optimized root growth and / or more developed root system • optimized nodulation, in particular rhizobia nodulation • larger leaf blade • larger size • increased plant weight • increased plant height • number of increased shoots • increased number of flowers per plant • increased branch growth • increased yield when grown in poor soils or unfavorable weather conditions • optimized photosynthetic activity • optimized pigment content (eg chlorophyll content) • earlier flowering • fruiting earlier • earlier and improved germination • earlier grain maturity • improved self-defense mechanisms • improved plant tolerance and stress resistance against biotic and abiotic stress factors such as fungi, bacteria, viruses, insects, heat stress, cold stress, drought stress, UV stress and / or salt stress • less nonproductive shoots • fewer dead basal leaves • less input required (such as fertilizer or water) • greener leaves • complete ripening under reduced vegetation periods • less fertilizer needed • less seed needed • easier harvesting • faster and more uniform ripening • longer shelf life • longer panicles • senescence retardation • stronger and / or more productive shoots • better ingredient extractability • improved seed quality (because they are sown in the following times for seed production) • reduced ethylene production and / or inhibition of its reception by the plant.

Improvement of plant vigor in accordance with the present invention particularly means that the improvement of any of the above-mentioned plant characteristics, any or all of them are improved independently of the pesticidal action of the mixture or active ingredients.

[071] In another preferred embodiment, the mixture according to the invention is used to synergistically improve plant strength (plant stanza / smaller accommodation) of a plant.

[072] In yet another preferred embodiment, the blend according to the invention is used to synergistically optimize root growth of a plant.

[073] In yet another preferred embodiment, the mixture according to the invention is used to synergistically increase a plant's yield when grown in poor soils or unfavorable weather conditions.

[074] Another indicator for plant condition is the "quality" of a plant and / or its products. According to the present invention, optimized quality means that certain plant characteristics, such as the content or composition of certain ingredients, are increased or improved by a measurable or noticeable amount about the same plant factor produced under the same conditions, but without the application of the mixtures of the present invention. Optimized quality can be characterized, among others, by the following improved properties of the plant or its product: • increased nutrient content • increased protein content • increased fatty acid content • increased metabolite content • increased carotenoid content • sugar content increased • increased amount of essential amino acids • improved nutrient composition • improved protein composition • improved fatty acid composition • improved metabolite composition • improved carotenoid composition • improved sugar composition • improved amino acid composition • optimal or improved fruit color • improved sheet color • increased storage capacity • increased processability of collected products.

[075] In a preferred embodiment, the mixture according to the invention is used to synergistically increase the sugar content of a plant.

[076] In another preferred embodiment, the mixture according to the invention is used to synergistically improve the processability of products collected from a plant.

[077] Another indicator for plant condition is plant tolerance or resistance to biotic and / or abiotic stress factors. Biotic and abiotic stress, especially over longer periods, can have detrimental effects on plants. Biotic stress is caused by living organisms, while abiotic stress is caused, for example, by extreme environmental conditions. According to the present invention, "optimized tolerance or resistance to biotic and / or abiotic stress factors" means that (1.) certain negative factors caused by biotic and / or abiotic stress are decreased by a measurable or noticeable amount as compared to plants exposed to the same conditions but not treated with a mixture according to the invention and that (2) the negative effects are not diminished by a direct action of the mixture according to the invention on stress factors, for example , by its fungicidal or insecticidal action that directly destroys microorganisms or pests, but preferably by stimulating the defensive reactions of the plants themselves against these stressors.

[078] Negative factors caused by biotic stress such as pathogens and pests are widely known and lie in the range of leaf spotted to total plant destruction. Biotic stress can be caused by living organisms such as: • pests (eg insects, arachnids, nematodes) • competing plants (eg weeds) • microorganisms such as fungi and / or phytopathogenic bacteria • viruses.

[079] Negative factors caused by abiotic stress are also well known and can often be observed as reduced plant vigor (see above), for example: spotted leaves, "burnt leaves", reduced growth, less flowers, less biomass. , less crop yields, reduced crop nutritional value, delayed crop maturity, to name a few. Abiotic stress can be caused, for example, by: • extremes in temperature, such as heat or cold (heat stress / cold stress) • strong temperature variations • unusual temperatures for the specific season • drought (drought stress) • extreme humidity • high salinity (salt stress) • radiation (eg, increased UV radiation due to decreasing ozone layer) • increased ozone levels (ozone stress) • organic pollution (eg, phytotoxic amounts of pesticides) • inorganic pollution (eg by heavy metal contaminants).

[080] As a result of biotic and / or abiotic stress factors, the quantity and quality of stressed plants, two crops, and fruits decrease. Regarding quality, reproductive development is usually severely affected with consequences on crops that are important for fruits or seeds. Protein synthesis, accumulation and storage are mainly affected by temperature; growth is retarded by almost all types of stress; Both structural and storage polysaccharide synthesis is reduced or modified: these effects result in a decrease in biomass (yield) and changes in the nutritional value of the product.

[081] In a preferred embodiment, the mixture according to the invention is used to synergistically increase the biotic stress tolerance of a plant.

In another preferred embodiment, the mixture according to the invention is used to synergistically increase a plant's tolerance against bacteria.

[083] In another preferred embodiment, the mixture according to the invention is used to synergistically increase a plant's tolerance against viruses.

[084] In an especially preferred embodiment, the mixtures according to the invention are used to synergistically increase the abiotic stress tolerance of a plant.

As a consequence of this, in an especially preferred embodiment, the mixture according to the invention is used to synergistically increase the drought tolerance of a plant.

[086] In another preferred embodiment, the mixtures according to the invention are used to synergistically increase a plant's tolerance against ozone stress.

Advantageous properties, obtained especially from treated seeds, consist for example of improved germination and field establishment, better vigor and / or a more homogeneous field establishment.

[088] As indicated above, the indicators identified above for the health of a plant may be interdependent and may result from one another. For example, increased resistance to biotic and / or abiotic stress may lead to better plant vigor, for example, better and larger crops and thus increased yield. Conversely, a more developed root system can result in increased resistance to biotic and / or abiotic stress. However, these interdependencies and interactions are not all known or fully understood and therefore the different indicators are described separately.

[089] In one embodiment, the use of mixtures within the methods according to the invention results in an increased yield of a plant or its product.

[090] In another embodiment, the use of the mixtures within the methods according to the invention results in an increased vigor of a plant or its product.

[091] In another embodiment, the use of the mixtures within the methods according to the invention results in an increased quality of a plant or its product.

[092] In yet another embodiment, the use of the mixtures within the methods according to the invention results in increased tolerance and / or resistance of a plant or its product against biotic and / or abiotic stress. In particular, the drought tolerance of a plant is increased within the methods according to the invention.

[093] In one embodiment of the invention, tolerance and / or resistance against biotic stressors is optimized. Thus, according to the preferred embodiment of the present invention, inventive mixtures are used to stimulate a plant's natural defensive reactions against a pathogen and / or pest. As a consequence, the plant can be protected against unwanted microorganisms such as fungi and / or phytopathogenic bacteria or even viruses and / or pests such as insects, arachnids and nematodes.

[094] In another embodiment of the invention, tolerance and / or resistance against abiotic stressors is optimized. Thus, in accordance with the preferred embodiment of the present invention, inventive mixtures are used to stimulate the plant's own defensive reactions against abiotic stress, such as extremes in temperature, for example, heat or cold or strong variations in temperature and / or temperature. unusual season-specific temperatures, drought, extreme humidity, high salinity, radiation (eg increased UV radiation due to decreasing ozone protective layer), increased ozone levels, organic pollution (eg phytotoxic amounts of pesticides) and / or inorganic pollution (eg by heavy metal contaminants).

[095] In a preferred embodiment of the invention, the blends according to the invention are used to increase plant weight, increase plant biomass (e.g. total fresh weight), increase grain yield, increase the number of renewals, for enhancing plant vitality, improving plant development, improving visual appearance, improving plant strength (smaller plant / accommodation), optimizing root growth and / or enhancing root system development, increase branch growth, increase the number of flowers per plant, increase crop yield when grown in poor soils or unfavorable weather conditions, optimize photosynthetic activity, optimize pigment content, improve flowering (early flowering), improve germination, improve tolerance and stress resistance of plants against biotic and abiotic stress factors such as such as fungi, bacteria, viruses, insects, heat stress, cold stress, drought stress, UV stress and / or salt stress, decrease the number of non-productive shoots, decrease the number of dead basal leaves, improve the greenness of the plants. leaves, reduce the input required such as fertilizer and water, reduce the seed needed to establish the crop, improve crop harvesting capacity, improve maturity uniformity, improve shelf life, delay senescence, strengthen productive shoots improve seed quality in seed production, improve fruit color, improve leaf color, improve storage capacity and / or improve processability of the collected product.

[096] In another preferred embodiment of the invention, the blends according to the invention are used to increase plant weight, increase plant biomass (e.g. total fresh weight), increase grain yield, increase the number of shoots, improve plant development, improve visual appearance, improve plant resistance (plant stance / smaller accommodation), increase crop yield when grown in poor soils or unfavorable weather conditions, improve germination, improve tolerance and plant stress resistance against abiotic stress factors such as cold stress, drought stress, UV stress, decrease the number of non-productive shoots, decrease the number of dead basal leaves, improve leaf greenness, reduce seed needed to establish the harvest, improve the harvesting capacity of the crop, improve the shelf life, r delay senescence, strengthen yields and / or improve seed quality in seed production.

[097] It should be emphasized that the above mentioned effects of the mixtures according to the invention, i.e. optimized plant health, are also present when the plant is not under biotic stress and in particular when the plant is not under stress. pest pressure. It is evident that a plant suffering from fungal or insecticidal attack produces a lower biomass and leads to a reduced harvest yield as compared to a plant that has been subjected to curative or preventative treatment against pathogenic fungus or other relevant pest and which may grow without the damage caused by the biotic stress factor. However, the method according to the invention leads to optimum plant health even in the absence of any biotic. This means that the positive effects of the inventive mixtures cannot be explained solely by the fungicidal and / or herbicidal activities of compounds (I) and (II), but are based on the additional activity profiles. Accordingly, in a preferred embodiment of the method, application of the active ingredients and / or mixtures thereof is performed in the absence of pest pressure. But, of course, plants under biotic stress can also be treated according to the methods of the present invention.

[098] Inventive mixtures are employed by treating the plant, plant propagating material (preferably seed), soil, area, material or environment in which a plant is growing or can grow with an effective amount of the active compounds. Application can be performed both before and after infection of plant propagating materials, plants or materials (preferably seeds) by pests.

[0105] In one embodiment of the method according to the invention, plants and / or plant propagules are treated simultaneously (together or separately) or subsequently with a mixture as described above. Of course, subsequent application is performed at a time interval that allows a combined action of the applied compounds. It is preferred that the time interval for a subsequent application of compound (I) and compound (II) be in the range from a few seconds to 3 months, preferably from a few seconds to 1 month, more preferably. , from a few seconds to 2 weeks, more preferably from a few seconds to 3 days, and in particular from 1 second to 24 hours.

Here, it has been found that the simultaneous application, ie together or separately, of a compound (I) and a compound (II) or the successive application of a compound (I) and a compound (II) allows a optimized increase of a plant's health compared to the control rates that are possible with individual compounds (synergistic mixtures).

In another embodiment of the invention, the mixture as described above is repeatedly applied. If this is the case, the application is repeated two to five times, preferably twice.

When used to increase the health of a plant, the application rates of the mixtures are between 0.3 g / ha and 3500 g / ha, depending on various parameters, such as the treated plant species or the applied mixture. In a preferred embodiment of the method according to the invention, the application rates of the mixtures are between 5 g / ha and 2000 g / ha. In a still more preferred embodiment of the method according to the invention, the application rates of the mixtures are between 20 g / ha and 900 g / ha, in particular from 20 g / ha to 750 g / ha.

In the treatment of plant propagating material (preferably seed), quantities from 0.01 g to 10 kg, in particular amounts from 0.01 g to 3 kg of mixtures according to the invention are generally required per 100 kilograms of plant propagating material (preferably seed).

As an obvious matter, the mixtures according to the invention are used in "non-phytotoxic and effective amounts". This means that they are used in an amount that gives the desired effect but does not cause any phytotoxic symptoms on the treated plant.

[0111] The compounds according to the invention may be present in different crystal modifications whose biological activity may differ. They also consist of the subject matter of the present invention.

In all mixtures used according to the methods of the present invention, compounds (I) and compounds (II) are employed in amounts that result in a synergistic effect.

With respect to binary mixtures, the weight ratio of compound (I) to compound (II) is preferably from 200: 1 to 1: 200, more preferably from 100: 1. at 1: 100, more preferably from 50: 1 to 1:50 and in particular from 20: 1 to 1:20. The ratio of maximum preference is 1: 10 to 10: 1.

Agrochemical mixtures are typically applied as compositions comprising an imidazolinone herbicide such as compound (I) and / or a fungicidal compound (II). In a preferred embodiment, the pesticidal composition comprises a liquid or solid carrier and a mixture as described above.

Plants, as well as the propagating material of said plants, which can be treated with inventive mixtures include all modified non-transgenic plants or transgenic plants, for example, crops that tolerate the action of herbicides, fungicides or insecticides. due to reproduction, which include genetic engineering methods, or plants having modified characteristics compared to existing plants, which may be generated, for example, by traditional breeding methods and / or by mutant generation or by of recombinant procedures.

For example, the mixtures according to the present invention may be applied as seed treatment, foliar spray treatment, furrow application or by any other means also to plants that have been modified by reproduction, mutagenesis or genetic engineering which have been modified. include, but are not limited to, commercially available or developing agricultural biotechnology products (see http://www.bio.org/speeches/pubs/er/agri_products.asp).

"Genetically modified plants" are plants in which genetic material has been modified using recombinant DNA techniques in a way that under natural circumstances cannot readily be obtained by cross-breeding, mutation or natural recombination. Typically, one or more genes have been integrated into the genetic material of a genetically modified plant to enhance certain plant properties. Such genetic modifications also include, but are not limited to, posttransitionally directed modification of protein (s), oligo- or polypeptides, for example by glycosylation or polymer additions such as prenylated, acetylated or farnesylated portions or PEG portions.

[0118] Plants that have been modified by reproduction, mutagenesis or genetic engineering, for example, have been made tolerant to applications of specific classes of herbicides. Herbicide tolerance can be achieved by creating insensitivity at the herbicide site of action by expressing a target enzyme that is herbicide resistant; rapid metabolism (conjugation or degradation) of the herbicide by the expression of herbicide inactivating enzymes; or unsatisfactory absorption and translocation of the herbicide. Examples are the expression of enzymes that are herbicide tolerant compared to wild type enzymes, such as the expression of 5-enol pyrruvate hydrochloride 3-phosphate synthase (EPSPS), which is tolerant. to glyphosate {see, for example, Heck etal, crop Sci. 45, 2005, 329-339; Funke et al., PNAS 103, 2006, 13010-13015; US 5188642, US 4940835, US 5633435, US 5804425, US 5627061), the expression of glutamine synthase that is tolerant of glufosinate and bialaphos (see, for example, US 5646024, US 5561236} and DNA constructs encoding enzyme degradation enzymes. dicamba (see for general reference US 2009/0105077, for example, US 7105724 for dicamba resistance in beans, corn (for corn, see also WO 08/051633), cotton (for cotton, see also US 5670454), pea, potato sorghum, soybeans (for soybeans, see also US 5670454), sunflower, tobacco, tomatoes (for tomatoes, see also US 5670454).)

[0157] Seed treatment can be done in the seed box before planting in the field.

For seed treatment purposes, the weight ratio in the binary or ternary mixtures of the present invention generally depends on the properties of the compounds of the inventive mixtures.

[0164] The following examples are intended for illustrate the invention but without imposing any limitation.

Examples Example 1 The transpiration of fluxapiroxade-treated or untreated wheat plants alone, imazamox alone and mixtures thereof was evaluated as an indicator for drought tolerance. The 10 to 14 day old wheat plants were cut above ground and placed in Eppendorf capsules containing 2.2 ml of the test solution. Wheat plants were incubated for 24h at 25 ° C and 50% relative humidity in a growth chamber. The weight of the Eppendorf capsule including the test solution but excluding the plant was assessed before and after incubation. The difference in weight is recorded as water loss through perspiration. This test can be used to assess drought tolerance of plants, [01 © 6 | In the present example, wheat plants of the imidazolinone tolerant variety BW755 'were grown at 18X for 10 days in the greenhouse before treatment and incubation, 10 plants per treatment were treated and incubated as described. Fluxapiroxade and imazamox were dissolved in 0.5% DMSG. The 0.5% DMSO solution consisted of 0.5% DMSO dissolved in water. The concentrations tested are described in Table 2. Control plants were treated with 0.5% DMSO blank solution only.

The efficacy of the tested compounds and mixtures thereof was calculated as% water loss compared to the control: E = (a / b-1) * 100 a corresponds to the water loss from plants after incubation in the treated plants. geb corresponds to the water loss of plants after incubation in the control in g.

[0168] An effectiveness of 0 means water loss, that is, the transpirated water in the treated plants corresponds to that of the untreated control; effectiveness of 100 means that the treated plants showed a 100% decrease in transpirated water. [0169] Expected efficiencies of compound combinations were estimated using the Coiby formula (Colby, SR, Calculating synergistic and antagonistic responses of herbicide). combinations, Weeds, 15, pp. 20-22, 1967) and compared with the observed efficiencies. Colby formula: E = x + y - x * y / 100 E expected efficacy, expressed as% of untreated control, when mixing active compounds A and B at concentrations a and b, expressed as% of untreated control , when using active ingredient A at concentration ay efficacy, expressed as% of untreated control, when using active ingredient B at concentration b Table 2: Water Loss Through Sweating from Fluxapiroxade-Treated or Untreated Plants, Imazamox or a Mixture Comprising Both Compounds * according to Colby Formula [0170] As can be seen from table 2, the 50 ppm fluxapiroxade applied alone decreases water loss through perspiration by about 18%. Similarly, 50 and 100 ppm imazamox decreased water loss when applied alone, while slightly increased perspiration (water loss) by 150 ppm. An evident decrease in perspiration, however, was surprisingly observed when fluxapiroxade and imazamox were applied. as a mixture according to the invention. The observed effectiveness in reducing perspiration was greater compared to the expected efficacy. Clearly, the mixture comprising fluxapiroxade and imazamox has a synergistic effect on drought tolerance (expressed as reduced perspiration or water loss) and thus on the health of a plant.

Example 2 [0171] Wheat was grown in 2010 in the greenhouse at the agricultural center in Limburgerhof, Germany. The imidazolinone tolerant variety 'BW755' was planted in pots. The test was set up with 8 replicates with one pot of 10 plants each per replica.

[0172] The active ingredients were used as formulations. The formulations were used at the product rates given below and in Table 3. The products were applied at a total spray volume of 375 l / ha. The products were diluted with water. The spray solution was applied to a spray box using a spray bar with flat blowing nozzles.

Imazamox was applied once as Raptor ™ (120 g active ingredient per liter of soluble concentrate) when wheat plants had the first leaf fully developed (BBCH 11). Fluxapiroxade was applied once as an experimental emulsion concentrate (62.5 g active ingredient per liter) to 2 to 3 fully developed leaves (BBCH 12/13). The application of the mixture was performed as a sequence, in which Raptor ™ was applied when the first leaf had developed, while the fluxpyroxade formulation was applied when 2 to 3 leaves had developed.

[0174] Total shoot biomass was evaluated (Table 3) by collecting all plants in a pot 7 days after the last treatment (expressed as g per pot). Subsequently, the dry weight of total shoot biomass per pot was evaluated. After fresh weight measurement, the samples were dried in a drying box at 65 ° C for two days. Efficacy was calculated as% biomass increase in treatments compared to untreated control: E = a / b-1 * 100 a corresponds to biomass of treated plants in g / pot and b corresponds to biomass of untreated plants (control) in g / pot An efficacy of 0 means that the yield level of the treated plants corresponds to that of the untreated control plants; An efficiency of 100 means that the treated plants showed a 100% biomass increase.

Expected efficacies of combinations of active compounds were estimated using Colby's formula (Colby, SR, Calculating synergistic and antagonistic responses of herbicide combinations, Weeds, 15, pp. 20-22, 1967) and compared with observed efficiencies. Colby formula: E = x + y - x * y / 100 E expected efficacy, expressed as% of untreated control, when mixing active compounds A and B at concentrations a and b, expressed as% of untreated control , when active ingredient A is used at concentration ay efficacy, expressed as% of untreated control, when active ingredient B is used at concentration b Table 3: Effect of Application by Fluxapiroxade and Imazamox on Growth Stage 11 and 12/13 fBBCHb Respectively, on Fresh Total Overhead Air Biomass of Potted Imidazolinone Tolerant Wheat * according to Colby Formula [0177] As can be seen from Table 3, a slight increase in dry air biomass could be observed when fluxapiroxade was applied alone. There is an effect of imazamox dosage rate on plant growth, evaluated as dry shoot biomass, with 35 g of imazamox per ha reducing dry biomass by about 14% and 8.75 g of imazamox increasing dry biomass. by about 6%. Surprisingly, the combination of fluxapiroxade application and imazamox application resulted in a synergistically increased plant growth expressed as an increase in dry weight of the shoot, specifically observing the negative effect on higher imazamox dosage rates of individual application.

[0178] The increase in dry weight of the shoot was larger than could be expected from the effects of individual applications of each compound. This clearly shows the effect of increased synergistic plant health of the imazamox and fluxapiroxade mixture on plant growth in imidazolinone tolerant plants.

Example 3 Sweating as an indicator of drought tolerance of fluxapiroxade-treated or untreated wheat plants alone, imazetapyr alone and mixtures thereof was evaluated. The 10 to 14 day old wheat plants were cut above ground and placed in Eppendorf capsules containing 2.2 ml of the test solution. Wheat plants were incubated for 24h at 25 ° C and 50% relative humidity in a growth chamber. Eppendorf capsule weight including test solution but excluding leaves was assessed before and after incubation. The difference in weight was recorded as water loss through perspiration. This test is generally used to assess drought tolerance of plants.

In the present example, wheat plants of the imidazolinone tolerant variety BW755 'were grown at 18 ° C for 10 days in the greenhouse before treatment and incubation. 10 plants per treatment were treated and incubated as described. Fluxiroxade and imazethapyr were dissolved in 0.5% DMSO. The 0.5% DMSO solution consisted of 0.5% DMSO dissolved in water.

The concentrations tested are as described in Table 4. Control plants were treated with 0.5% DMSO blank solution only.

A. The efficacy of the tested compounds and mixtures was calculated as% water loss compared to the control: E = (a / b-1) · 100 a corresponds to the water loss of plants after incubation in the treated plants. in geb corresponds to the water loss of plants after incubation in the control in g.

An effectiveness of 0 means that the water loss, i.e. transpirated water, in treated plants corresponds to that of untreated control; effectiveness of 100 means that the treated plants showed a 100% decrease in transpirated water. [0183] Expected efficiencies of compound combinations were estimated using the Colby formula (Colby, SR, Synergistic and antagonistic responses of herbicide). combinations, Weeds, 15, pp, 20-22, 1967) and compared with observed efficiencies, Colby's formula: E = x + yx * y / 100 E expected efficacy, expressed as% of untreated control, when using the Mixture of active compounds A and B at concentrations a and b efficacy, expressed as% of untreated control, when using active ingredient A at concentration a and efficacy, expressed as% of untreated control, when using active ingredient B at concentration b Table 4: Loss of water through perspiration of plants treated or NOT TREATED WITH FLUXAFIROXADE. 1MAZETAPIR OR A MIX UNDERSTANDING BOTH COMPOUNDS * according to Colby's Formula [0184] As can be derived from Table 4, when fluxapiroxade was applied alone decreases water loss, reflecting increased drought tolerance of plants, Similarly, 500 ppm imazethapyr decreases water loss when applied alone, but increases perspiration (water loss) by 1 ppm.

A significant decrease in perspiration, however, was surprisingly observed only when fluxapiroxade and imazetapir were applied as a mixture according to the invention. The observed efficacy in reducing perspiration was greater compared to the expected efficacy. [0187] Clearly, the inventive mixture of fluxapiroxade and imazetapir has a synergistic effect on drought tolerance expressed as a reduction in perspiration or water loss and therefore about the health of a plant.

[0188] The experiment as described above was repeated at the concentrations shown in Table 5. [0189] Again, fluxapiroxade applied alone decreases water loss, indicating an increase in plant drought tolerance, while imazethapyr alone by 10%. ppm tended to be neutral.

[0190] The combinations tested in this second experiment again showed a clear synergistic effect on reducing water loss and thus increasing the drought tolerance of plants.

Table 5: Water Loss Through Sweating and Plants Treated or Untreated with Fluxapiroxade, Imazetapyr or a Mixture of Both Compounds. * according to Colby's Formula Example 4 [0191] Wheat was grown in 2010 in the greenhouse at the agricultural center in Limburgerhof, Germany. The imidazolinone tolerant variety 'BW755' was planted in pots. The test was set up with 8 replicates with one pot of 10 plants each per replica. [0192] The active ingredients were used as formulations. The formulations were used at the product rates given below and in table 6.

The products were applied in a total spray volume of 375 l / ha. The products were diluted with water. The spray solution was applied to a spray box using a spray bar with flat blowing nozzles.

Imazetapyr was applied once as PIVOT 100 SL ™ (100 g active ingredient per liter of soluble concentrate) when wheat plants had the first leaf fully developed (BBCH 11). The fluxapiroxade was applied once as an experimental emulsion concentrate (62.5 g active ingredient per liter) when 2 to 3 leaves were fully developed (BBCH 12/13). The application of the mixture was applied as a PIVOT 100 sequence. SL ™ at the stage when the first leaf had developed and while the fluxapiroxade formulation was applied when 2 to 3 leaves had developed.

[0194] Total shoot biomass was evaluated (Table 6) by collecting all plants from a pot 7 days after the last treatment (expressed as g per pot). The dry weight of total shoot biomass per pot was evaluated. After fresh weight measurement, samples were dried in a drying box at 65 BC for two days. Efficacy was calculated as% biomass increase in treatments compared to untreated control: E = a / b-1 * 100 a corresponds to the biomass of the treated plants in g / pot and b corresponds to the biomass of the untreated (control) plants in g / pot [0195] Efficacy of 0 means that the yield level of the treated plants corresponds to that of the untreated plants of control; an efficiency of 100 means that the treated plants showed a 100% biomass increase. [0196] Expected efficiencies of the active compound combinations were estimated using Colby's formula (Colby, SR, Calculating synergistic and antagonistic responses of herbicide). combinations, Weeds, 15, pp, 20-22, 1967) and compared with the observed efficiencies. Colby formula: E = x + y - x * y / 100 E expected efficacy, expressed as% of untreated control, when mixing active compounds A and B at concentrations a and b, expressed as% of untreated control , when using active ingredient A at concentration ay efficacy, expressed as% of untreated control, when using active ingredient B at concentration b Table 6: Effect of Fluxapiroxade and imazetapyr Application on Growth Stage 11 and 12/13 (BBCH), Respectively, on Biomass or Fresh Total Aerial Part of Potted Imidazolinone Tolerant Wheat * according to Colby's Formula [0197] As can be seen from Table 6, a decrease in biomass of dry aerial part could be observed when fiuxapiroxade was applied alone in the present example. In addition, there is an effect of imazetapyr dosage rate on plant growth, evaluated as dry shoot biomass, with 35 g of imazetapir per ha reducing dry biomass by about 9% and 17.5 g of imazetapyr per ha reducing dry biomass by only about 1%. Surprisingly, however, the combination of fiuxapiroxade application and imazetapir application according to the invention resulted in overcoming those partially negative effects, leading even to an increase in plant growth. expressed as an increase in dry weight of the shoot (biomass). This effect is highly unexpected as calculations according to Colby's formula indicated a much more severe negative effect on growth. This impressively shows the synergistic effect of the combination of imazetapyr and fiuxapiroxade on plant growth, biomass and therefore on plant health.
