FIELD OF THE INVENTION:
The present invention relates to novel agrochemical composition. More particularly, the present invention relates to a ternary composition comprising as component (1) at least one phenylamidine compound of formula (I); as component (2) at least one fungicide selected from azoxy strobin, metominostrobin, picoxystrobin, trifloxystrobin, pyraclostrobin, metyltetraprole, benzovindiflupyr, bixafen, fluxapyroxad, fluindapyr, inpyrfluxam, mefentrifluconazole, cyproconazole, tebuconazole, prothioconazole, chlorothalonil, mancozeb and their salts; and as component (3) at least one additional fungicide, which is different from the compounds of components (1) and (2), selected from the groups (A) inhibitors of the sterol biosynthesis, (B) inhibitors of the respiratory chain at complex I or II, (C) inhibitors of the respiratory chain at complex III, (D) compounds capable to have a multisite action, or (E) inhibitors of histone deacetylase. Further, the agrochemical composition, according to the invention, relate to a method for controlling microorganisms such as phytopathogenic fungi and bacteria.
BACKGROUND OF THE INVENTION:
It is widely known that various fungicidal compounds out of different chemical classes are already used as fungicides for applications in various crops of cultivated plants. However, crop tolerance and spectrum of activity as well as the level of efficacy against phytopathogenic fungi on plants do not always satisfy the needs of the agricultural practice in many incidents and aspects. In order to overcome this problem, binary mixtures of arylamidine derivatives with certain fungicides have been provided in W02003024219, W02005089547, WO2018228896, W02007031507 and WO2022113033 discloses fungicide compositions comprising a N2-phenylamidine derivative together with other fungicidal compounds.
Recently, practical agricultural experience has shown that the repeated and exclusive application of an individual active compound or a binary mixture in the control of harmful fungi lead to natural or adapted resistance by fungus strains against the active compound in question. Effective control of these fungi with the active compound and/or binary mixture in question is then no longer possible.
Fungicides, that effectively control plant pathogens with a reduced quantity of the chemical agent released in the environment, are always desirable. Additionally, there is a constant need to broaden the spectrum of activity, reduce undesirable environmental effects and lower the application rates. The present invention provides agrochemical composition, which, in some of these aspects, at least achieve the stated objectives.
Surprisingly it has been found that the novel agrochemical composition, according to the invention, not only bring about the additive enhancement of the spectrum of activity with respect to the phytopathogens
to be controlled, that was in principle to be expected, but also achieve a synergistic effect. The synergistic effect of the agrochemical composition of the present invention helps to reduce the application rate of component (1), component (2) and component (3) by maintaining the level of efficacy even if the three individual compounds alone have become widely ineffective at such low application rates. Over and above, it allows a substantial broadening of the spectrum of phytopathogens that can be controlled, by, at the same time, increasing the safety in use.
In addition to the fungicidal synergistic activity, the agrochemical composition, according to the invention, have further surprising properties, which, in a wider sense, may also be called synergistic, such as, for example: broadening of the activity spectrum to more phytopathogens, for example to resistant strains of plant diseases; lower application rates of the active compounds; sufficient control of plant diseases with the aid of the agrochemical composition according to the invention even at application rates where the individual compounds showed virtually no activity; advantageous behavior during formulation or during use, for example during grinding, sieving, emulsifying, dissolving or dispensing; improved storage and light stability; advantageous residue formation; improved toxicological or eco-biological behavior; improved properties of the so called effects on plant physiology, for example better growth, increased harvest yields, a better developed root system, a larger leaf area, greener leaves, stronger shoots, less seed required, mobilization of the defense system of the plant, and good plant compatibility.
Thus, the use of the novel agrochemical composition, according to the invention, contribute considerably, for example, to keep young soybean plants healthy to safeguard quality and yield.
Moreover, the novel agrochemical composition, according to the invention, may contribute to an increased systemic action. Even if the individual compounds of the composition do not have sufficient systemic properties, the novel agrochemical composition, according to the invention, may still have this property. In a similar manner, the novel agrochemical composition, according to the invention, may result in higher long lasting efficacy of the fungicidal action.
SUMMARY OF THE INVENTION:
Accordingly, the present invention provides novel agrochemical composition comprising: a mixture of component (1), and at least two components selected from component (2), component (3), or a combination of component (2) and component (3), wherein the component (1) is at least one phenylamidine compound of formula (I)

R5 and R6 are independently selected from the group consisting of hydrogen, halogen, cyano, methyl, halomethyl, and methoxy; or
R5 and R6, together with the carbon atom to which they are bound, form a cyclopropyl;
R7 is selected from the group consisting of hydrogen, halogen, cyano, methyl, ethyl, isopropyl, halomethyl, methoxy, ethoxy, isopropoxy, halomethoxy, haloethoxy and cyclopropyl; n represent integers 0, 1, 2, 3 or 4; and salts, A-oxides, metal complexes or stereoisomers thereof; as component (2) at least one fungicide selected from azoxystrobin, metominostrobin, picoxystrobin, trifloxystrobin, pyraclostrobin, metyltetraprole, metarylpicoxamid, benzovindiflupyr, bixafen, fluxapyroxad, fluindapyr, inpyrfluxam, difenoconazole, mefentrifluconazole, cyproconazole, tebuconazole, prothioconazole, chlorothalonil, mancozeb or their salts; and as component (3) at least one fungicide different from components (1) and (2) selected from the groups:

It has been found that the action of the composition comprising components (1), (2) and (3) as defined herein goes far beyond the fungicidal and/or plant health improving action of the individual active components (synergistic action).
Moreover, we have found that, simultaneously, that is joint or separate, the application of the components (1), (2) and (3) or a successive application in a short time interval of the components (1), (2) and (3) allows enhanced control of harmful fungi and/or plant health effects, compared to the control rates and/or plant health effects that are possible with the individual components (synergistic mixtures).
In another embodiment, the present invention provides a method for controlling unwanted microorganisms, such as unwanted fungi and bacteria, comprising the step of applying at least one novel agrochemical composition, according to the invention, to the microorganisms and/or to their habitat (to the plants, plant parts, seeds, fruits or to the soil in which the plants grow).
In yet another embodiment, the present invention provides a composition for use in seed treatment, and a method for treating the seed for protecting the plants that grow from the seed after germination.

In one embodiment, the present invention provides a method for controlling or preventing infestation of
useful plants by phytopathogenic fungi in agricultural crops and/or horticultural crops, comprising applying an agrochechemically effective amount of a said composition as described in the present invention to the plant or parts thereof, or to the plant seeds, or to a locus thereof.
The term “control” or “controlling” as used herein encompasses curative and protective treatment of unwanted microorganisms. The unwanted microorganisms may be pathogenic bacteria or pathogenic fungi, more specifically phytopathogenic bacteria or phytopathogenic fungi.
The term "locus thereof" includes soil, surroundings of plant or plant parts and equipment or tools used before, during or after sowing/planting a plant or a plant part.
In the context of the present invention, "control of harmful microorganisms" means a reduction in infestation by harmful microorganisms, compared with the untreated plant measured as fungicidal efficacy, preferably a reduction by 25-50 %, compared with the untreated plant (100 %), more preferably a reduction by 40-79 %, compared with the untreated plant (100 %); even more preferably, the infection by harmful microorganisms is entirely suppressed (by 70-100 %). The control may be curative, i.e. for treatment of already infected plants, or protective, for protection of plants which have not yet been infected.
An "effective but non-phytotoxic amount" or “agrochechemically effective amount” means an amount of the novel agrochemical composition which is sufficient to control the fungal disease of the plant in a satisfactory manner or to eradicate the fungal disease completely, and which, at the same time, does not cause any significant symptoms of phytotoxicity. In general, this application rate may vary within a relatively wide range. It depends on several factors, for example, on the fungus to be controlled, the plant, the climatic conditions and the ingredients of the inventive compositions.
The novel agrochemical composition according to the invention can be applied to any plants or plant parts.
Plants mean all plants and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants may be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the genetically modified plants (GMO or transgenic plants) and the plant cultivars which are protectable and non-protectable by plant breeders' rights.
Genetically modified plants (GMO or transgenic plants) are plants of which a heterologous gene has been stably integrated into the genome. The expression "heterologous gene" essentially means a gene which is provided or assembled outside the plant and then introduced in the nuclear, chloroplastic or mitochondrial genome. This gene gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by down regulating or silencing other gene(s) which are present in the plant (using for example, antisense technology, cosuppression technology, RNA
interference - RNAi - technology or microRNA - miRNA - technology). A heterologous gene, located in the genome, is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.
Plant cultivars are understood to mean plants which have new properties ("traits") and have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. They can be cultivars, varieties, bio- or genotypes.
According to the invention all plants and plant parts can be treated. By plants is meant all plants and plant populations such as desirable and undesirable wild plants, cultivars and plant varieties (whether or not protectable by plant variety or plant breeder's rights). Cultivars and plant varieties can be plants obtained by conventional propagation and breeding methods which can be assisted or supplemented by one or more biotechnological methods such as by use of double haploids, protoplast fusion, random and directed mutagenesis, molecular or genetic markers or by bioengineering and genetic engineering methods. By plant parts is meant all above ground and below ground parts and organs of plants such as shoot, leaf, blossom and root, whereby for example, leaves, needles, stems, branches, blossoms, fruiting bodies, fruits and seed as well as roots, conns and rhizomes are listed. Crops and vegetative and generative propagating material, for example, cuttings, conns, rhizomes, runners and seeds also belong to plant parts.
Plant parts are understood to mean all parts and organs of plants above and below the ground, such as shoots, leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material and vegetative and generative propagation material, for example, cuttings, tubers, rhizomes, slips and seeds.
Plants which can be treated in accordance with the methods of the invention include the following: cotton, flax, grapevine, fruit, vegetables, such as Rosaceae sp.

The novel agrochemical compositions according to the invention have a potent microbicidal activity. They can be used for controlling unwanted microorganisms, such as unwanted fungi and bacteria. They can be particularly useful in crop protection (by controlling microorganisms that cause plants diseases). More specifically, the agrochemical composition according to the invention can be used to protect seeds, germinating plants, emerged seedlings, plants, plant parts, fruits and the soil in which the plants grow from unwanted microorganisms.
The fact that the novel agrochemical compositions according to the invention are well tolerated by plants at the concentrations required for controlling plant diseases allows the treatment of above-ground parts of plants, of propagation stock and seeds, and of the soil.
Effective and non-phytotoxic amount means an amount that is sufficient to control or destroy the fungi present or liable to appear on the cropland and that does not entail any appreciable symptom of phytotoxicity for said crops. Such an amount can vary within a wide range depending on the fungus to be controlled, the type of crop, the climatic conditions and the respective composition of the invention used. This amount can be determined by systematic field trials that are within the capabilities of a person skilled in the art.
The agrochemical composition of the present invention can be used for curative or protective/preventive
control of phytopathogenic fungi. The present invention therefore also relates to curative and protective methods for controlling phytopathogenic fungi by use of the novel agrochemical composition, which are applied to the seed, the plant or plant parts, the fruits or the soil in which the plants grow.
The novel agrochemical composition according to the invention, when they are well tolerated by plants, have favorable homeotherm toxicity and are well tolerated by the environment, are suitable for protecting plants and plant organs, for enhancing harvest yields and for improving the quality of the harvested material. They can preferably be used as crop protection compositions. They are active against normally sensitive and resistant species and against all or some stages of development.
In addition, the novel agrochemical composition of the invention can reduce the mycotoxin content in the harvested material and the foods and feeds prepared therefrom. Mycotoxins include particularly, but not exclusively, the following: deoxynivalenol (DON), nivalenol, 15 -Ac-DON, 3-Ac-DON, T2- and HT2- toxin, fumonisins, zearalenon, moniliformin, fusarin, diaceotoxyscirpenol (DAS), beauvericin, enniatin, fusaroproliferin, fusarenol, ochratoxins, patulin, ergot alkaloids and aflatoxins which can be produced, for example, by the following fungi: Fusarium spec., such as F. acuminatum, F. asiaticum, F. avenaceum, F croobvellense, F culmorum, F graminearum (Gibberella zeae), F equiseti, F fujikoroi, F musarum, F oxysporum, F proliferatum, F poae, F pseudo graminearum, F. sambucinum, F. scirpi, F semitectum, F solani, F sporotrichoides, F langsethiae, F. subglutinans, F. tricinctum, F verticillioides etc., and also by Aspergillus spec., such as A. jlavus, A. parasiticus, A. nomius, A. ochraceus, A. clavatus, A. terreus, A. versicolor, Penicillium spec., such as P. verrucosum, P. viridicatum, P. citrinum, P. expansum, P. claviforme, P. roqueforti, Claviceps spec., such as C. purpurea, C. fusiformis, C. paspali, C. africana, Stachybotlys spec, and others.
In one, the novel agrochemical composition is used for foliar application.
The novel agrochemical composition of the invention may intervene in physiological processes of plants and can therefore also be used as plant growth regulators.
Application of the inventive compositions to useful plants may also lead to an increase in the crop yield.
The novel agrochemical composition of the invention also exhibits a potent strengthening effect in plants. Accordingly, they can be used for mobilizing the defences of the plant against attack by undesirable microorganisms.
Plant-strengthening (resistance-inducing) substances in the present context are substances capable of stimulating the defence system of plants in such a way that the treated plants, when subsequently inoculated with undesirable microorganisms, develop a high degree of resistance to these microorganisms.
Further, in context with the present invention plant physiology effects comprise the following:
Abiotic stress tolerance, comprising tolerance to high or low temperatures, drought tolerance and recovery after drought stress, water use efficiency (correlating to reduced water consumption), flood tolerance, ozone stress and UV tolerance, tolerance towards chemicals like heavy metals, salts, pesticides etc.
Biotic stress tolerance comprising increased fungal resistance and increased resistance against nematodes, viruses and bacteria. In context with the present invention, biotic stress tolerance preferably comprises increased fungal resistance and increased resistance against nematodes.
In another embodiment, the present invention provides a fungicidal composition for treating seed, seed of transgenic plants and transgenic plants.
The novel agrochemical composition of the present invention is also suitable for treating seed. A large part of the damage to crop plants caused by harmful organisms is triggered by the infection of the seed during storage or after sowing as well as during and after the germination of the plant. This phase is particularly critical since the roots and shoots of the growing plant are particularly sensitive, and even minor damage may result in the death of the plant. There is therefore a great interest in protecting the seed and the germinating plant by using appropriate compositions.
The control of phytopathogenic fungi by treating the seed of plants has been known for a long time and is the subject of constant improvements. However, the treatment of seed entails a series of problems which cannot always be solved in a satisfactory manner. For instance, it is desirable to develop methods for protecting the seed and the germinating plant, which dispense with, or at least significantly reduce, the additional deployment of crop protection compositions after planting or after emergence of the plants. It is also desirable to optimize the amount of the active ingredient used to provide the best possible protection for the seed and the germinating plant from an attack by phytopathogenic fungi, but without damaging the plant itself by the active ingredient employed. In particular, methods for the treatment of seed should also take account of the intrinsic fungicidal properties of transgenic plants in order to achieve optimal protection of the seed and the germinating plant with a minimum expenditure of crop protection compositions.
For treatment of seed with the seed dressing formulations usable in accordance with the invention, or the preparations prepared therefrom by adding water, all mixing units usable customarily for the seed dressing are useful. Specifically, the procedure in the seed dressing is to place the seed into a mixer, to add the particular desired amount of seed dressing formulations, either as such or after prior dilution with water, and to mix everything until the formulation is distributed homogeneously on the seed. If appropriate, this is followed by a drying process.
The novel agrochemical compositions are suitable for protecting seeds of any plant variety which is used
in agriculture, in greenhouses, in forests or in horticulture and viticulture. In particular, seeds of cereals (such as wheat, barley, rye, triticale, sorghum/millet and oats), maize, cotton, soyabean, rice, potato, sunflower, bean, coffee, beet (for example, sugar beet and fodder beet), peanut, oilseed rape, poppy, olive, coconut, cocoa, sugar cane, tobacco, vegetables (such as tomato, cucumbers, onions and lettuce), turf and ornamentals (see also below). The treatment of seeds of cereals (such as wheat, barley, rye, triticale and oats), maize, rice and soybean is of particular significance.
As also described herein, the treatment of transgenic seed with the novel agrochemical composition is of particular significance. This relates to the seed of plants containing at least one heterologous gene which enables the expression of a polypeptide or protein having insecticidal properties. The heterologous gene in transgenic seed can originate, for example, from microorganisms of the species Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter, Glomus or Gliocladium. This heterologous gene preferably originates from Bacillus sp., in which case the gene product is effective against the European maize borer and/or the western maize rootworm. The heterologous gene more preferably originates from Bacillus thuringiensis.
In the context of the present invention, the novel agrochemical composition is applied to the seed alone or in a suitable formulation. Preferably, the seed is treated in a state in which it is sufficiently stable for no damage to occur in the course of treatment. In general, the seed can be treated at any time between harvest and sowing. It is customary to use seed which has been separated from the plant and freed from cobs, shells, stalks, coats, hairs or the flesh of the fruits. For example, it is possible to use seed which has been harvested, cleaned and dried down to a moisture content of less than 15 % by weight. Alternatively, it is also possible to use seed which, after drying, for example, has been treated with water and then dried again.
The control of phytopathogenic fungi which damage plants post-emergence is affected primarily by treating the soil and the above-ground parts of plants with crop protection compositions. Owing to the concerns regarding a possible influence of the crop protection compositions on the environment and the health of humans and animals, there are efforts to reduce the amount of active ingredients deployed.
One of the advantages of the present invention is that, in particular, the systemic properties of the novel agrochemical composition not only protect the seed itself, but also the resulting plants after emergence, from phytopathogenic fungi.
Digital Technologies
The composition of the invention can be used in combination with models e.g. embedded in computer programs for site specific crop management, satellite farming, precision farming or precision agriculture. Such models support a site specific management of agricultural sites with data from various sources such
as soils, weather, crops (e.g. type, growth stage, plant health), weeds (e.g. type, growth stage), diseases, pests, nutrients, water, moisture, biomass, satellite data, yield etc. with the purpose to optimize profitability, sustainability and protection of the environment. Particularly, such models can help to optimize agronomical decisions, control the precision of the pesticide applications and record the work performed.
As an example, the composition of the invention can be applied to a crop plant according to an appropriate dose regime if a model, models the development of a fungal disease and calculates that a threshold has been reached for which it is recommendable to apply the composition of the invention to the crop plant.
Commercially available systems which include agronomic models are e.g. FieldScriptsTM from The Climate Corporation, XarvioTM from BASF, AGLogicTM from John Deere, etc.
The composition of the invention can also be used in combination with smart spraying equipment such as e.g. spot spraying or precision spraying equipment attached to or housed within a farm vehicle such as a tractor, robot, helicopter, airplane, unmanned aerial vehicle (UAV) such as a drone, etc. Such an equipment usually includes input sensors (such as e.g. a camera) and a processing unit configured to analyze the input data and provide a decision, based on the analysis of the input data, to apply the compound of the invention to the crop plants (respectively the weeds) in a specific and precise manner. The use of such smart spraying equipment usually also requires position systems (e.g. GPS receivers) to localize recorded data and to guide or to control farm vehicles; geographic information systems (GIS) to represent the information on intelligible maps, and appropriate farm vehicles to perform the required farm action such as the spraying.
In an example, diseases can be detected from imagery acquired by a camera. The disease can be identified and/or classified based on that imagery. Such identification and / classification can make use of image processing algorithms. Such image processing algorithms can utilize machine learning algorithms, such as trained neutral networks, decision trees and utilize artificial intelligence algorithms. In this manner, the compounds described herein can be applied only where needed.
Positive crop response:
The composition of the present invention not only control plant pathogens effectively but also show positive crop response such as plant growth enhancement effects like increased root growth, enhanced tolerance to drought, high salt, high temperature, chill, frost or light radiation, improved flowering, enhanced nutrient utilization (such as improved nitrogen assimilation), enhanced quality of plant products, more number of productive tillers, enhanced resistance to insect pests and the like, which results in higher yields.
Synergystic effect:
The compositions comprising the compound of formula (I) as component (1), the component (2) and the
component (3) at specific ratios are advantageously chosen so as to produce a synergistic effect.
The expected efficacies of the composition comprising the active components may be determined using Colby's formulas (Colby, S.R. "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds, Volume 15, Issue 1, January 1967, pp. 20-22).
According to the present invention, the efficacy of a composition or mixture is greater than the sum of the efficacies of the individual components, hence the composition shall be considered as a synergistic combination or a synergistic mixture.
Colby's formulas:
The expected activity for a given composition of three active components (ternary composition) can be calculated as follows:
X: efficacy, expressed in % of the untreated control, when using the active component (1) at the concentration a,
Y: efficacy, expressed in % of the untreated control, when using the active component (2) at the concentration b
Z: efficacy, expressed in % of the untreated control, when using the active component (3) at the concentration c.
E is the efficacy when the active compounds (1), (2) and (3) are applied at application rates of a, b and c.
However, besides the actual synergistic action with respect to fungicidal activity, the composition, according to the invention can also have further surprising advantageous properties. Examples of such advantageous properties that may be mentioned are: more advantageuos degradability, improved toxicological and/or ecotoxicological behaviour and improved plant growth and health that leads to higher yields including: better emergence, better developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf colour, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, improved plant vigor, and early germination.

Biological Test Examples
The methods followed to check the efficacy of the single compound and the respective composition on different pathogens were as following:
Example A: Pyricularia oryzae test in rice
The single compounds or respective composition were dissolved in 2% dimethyl sulfoxide/acetone and then mixed with water containing emulsifier to a calibrated spray volume of 30 mL. The test solutions were poured into spray bottles for further applications.
To test the preventive activity of compounds, healthy young rice plants, raised in the greenhouse, were sprayed with the single compound or its respective composition at the stated application rates inside the spray cabinets using hollow cone nozzles. One day after treatment, the plants were inoculated with a spore suspension containing 1.4xl06 Pyricularia oryzae inoculum. The inoculated plants were then kept in a greenhouse chamber at 24 °C temperature and 95 % relative humidity for disease expression.
A visual assessment of the performance of the single compounds or respective composition was carried out by rating the disease severity (0-100% scale) on treated plants 3, 7, 10 and 15 days after application. Efficacy (% control) of the single compound and its composition were calculated by comparing the disease rating in the treatment with the one of the untreated, inoculated control plants.
