The present invention relates to novel triazole derivatives, to processes for preparing these compounds, to compositions comprising these compounds, and to the use thereof as biologically active compounds, especially for control of harmful microorganisms in crop protection and in the protection of materials and as plant growth regulators.
It is already known that particular phenoxy-phenyl-substituted triazole derivatives show fungicidal efficacy (e.g. EP-A 0 275 955; J. Agric. Food Chem. 2009, 57, 4854-4860; CN-A 101225074, DE-A 40 03 180; EP-A 0 113 640; EP-A 0 470 466; U.S. Pat. No. 4,949,720; EP-A 0 126 430, DE-A 38 01 233; WO-A 2013/007767; WO-A 2013/010862; WO-A 2013/010885; WO-A 2013/010894; WO-A 2013/024075; WO-A 2013/024076; WO-A 2013/024077; WO-A 2013/024080; WO-A 2013/024081; WO-A 2013/024082; WO-A 2013/024083 and WO-A 2014/082872). It is also known that particular phenoxy-phenyl-substituted triazolethione derivatives (e.g. WO-A 2010/146114), particular hetaryloxy-phenyl-substituted triazolethione derivatives (e.g. WO-A 2010/146115) and particular phenoxy-hetaryl- and heterocyle-O-hetaryl-substituted triazole and triazolethione derivatives (e.g. WO-A 2010/146116 and WO-A 2017/029179) can be used in crop protection as fungicides.
Since the ecological and economic demands made on modern active ingredients, for example fungicides, are increasing constantly, for example with respect to activity spectrum, toxicity, selectivity, application rate, formation of residues and favourable manufacture, and there can also be problems, for example, with resistances, there is a constant need to develop novel fungicidal compositions which have advantages over the known compositions at least in some areas.
In order to address this need, novel phenoxy-heteroaryl-substituted triazole derivatives have been developed.
Accordingly, the present invention provides novel triazole derivatives of formula (I)
wherein

Illustration of the Processes and Intermediates
The present invention is furthermore related to processes for preparing compounds of formula (I). The present invention furthermore relates to intermediates such as compounds of formulae (IV), (V), (Va), (VI), (VII), (IX), (X), (XI) and (XXI) and the preparation thereof.
The compounds (I) can be obtained by various routes in analogy to prior art processes known (see e.g. J. Agric. Food Chem. (2009) 57, 4854-4860; EP-A 0 275 955; DE-A 40 03 180; EP-A 0 113 640; EP-A 0 126 430; WO-A 2013/007767 and references therein) and by synthesis routes shown schematically below and in the experimental part of this application. Unless indicated otherwise, the radicals Y, R, R1, R2, R3, R4, m and n have the meanings given above for the compounds of formula (I). These definitions apply not only to the end products of the formula (I) but likewise to all intermediates.
If individual compounds (I) cannot be obtained by those routes, they can be prepared by derivatization of other compounds (I).
Only for better understanding of the following Schemes the alcohols of formula (I) are named as alcohols (I-H) and compounds of formula (I), wherein R4 is ethynyl and m is 1, are named ethynyls (I-ethynyl), although such alcohols (I-H) and ethynyls (I-ethynyl) are encompassed by general formula (I) as defined above.
Process A (Scheme 1):
The compounds (II) and (III) (Scheme 1) can be converted by means of methods described in the literature to the corresponding compounds (IV) and subsequently to compounds (Va), (VI), (VII), (I-H) and (I) (see WO-A 2013/007767). Phenols (II) are reacted with aryls (III), wherein X stands for F or Cl and Z stands for Br or I. Z is in particular Br and the reaction is optionally performed in the presence of a base to obtain compounds (IV). These intermediates, in particular with Z being Br, are then transformed into Grignard reagents by the reaction with magnesium or by transmetallation reactions with reagents such as isopropylmagnesium halides and subsequently reacted with acetyl chloride to yield acetophenones (Va). Those reactions are preferably performed under anhydrous conditions and in the presence of a catalyst such as CuCl, CuCl2, AlCl3, LiCl and mixtures thereof. Compounds (Va) can be halogenated in a next step, for instance with Cl2 or Br2 in order to obtain α-haloketones (VI). The reactions are preferably carried out in an organic solvent such as diethyl ether, methyl tert.-butyl ether, methanol or acetic acid. The halogen in α-position, preferably Cl or Br, can be subsequently replaced by a 1,2,4-triazole. Preferably, this transformation is being conducted in the presence of a base, such as Na2CO3, K2CO3, Cs2CO3, NaOH, KOtBu, NaH or mixtures thereof, preferably in the presence of an organic solvent, such as tetrahydrofuran, dimethylformamide or toluene. Ketones (VII) are subsequently reacted with nucleophilic substrates, such as Grignard reagents R1MgBr or organolithium compounds R1Li or a hydride donor such as sodium borohydride to obtain alcohols (I-H). These transformations are preferably conducted under anhydrous conditions, optionally in the presence of a Lewis acid such as LaCl3×2LiCl or MgBr2×OEt2. After further derivatization of alcohol (I-H) with an alkylating agent R2-LG compounds of the general formula (I) can be obtained. LG is a replaceable group such as halogen, alkylsulfonyl, alkylsulfonyloxy and arylsulfonyloxy, preferably Br, I and methylsulfonyloxy. These derivatizations are optionally performed in the presence of a base such as NaH and in the presence of an organic solvent such as tetrahydrofuran.
Process B (Scheme 2):
Compounds of the general structure (II), in particular with Z being Br, are being transformed into Grignard reagents by the reaction with magnesium or by transmetallation reactions with reagents such as isopropylmagnesium halides and subsequently reacted with acyl chlorides to yield ketones (VIII). Those reactions are preferably performed under anhydrous conditions and in the presence of a catalyst such as CuCl2, AlCl3, LiCl and mixtures thereof. Ketones (VIII) are subsequently reacted with Phenols (II), optionally in the presence of a base such as K2CO3 or Cs2CO3 and a solvent such as DMF (dimethylformamide), to obtain compounds (V). Alternatively, compounds (V) can be produced by the reaction of (IV) with magnesium or transmetallation reagents and subsequent reaction with acyl chlorides R1COCl. Those reactions are preferably performed under anhydrous conditions and in the presence of a catalyst such as CuCl2, AlCl3, LiCl and mixtures thereof, Z being preferably Br. Thereafter, intermediates (V) can be converted by means of methods described in the literature to the corresponding epoxides (IX) (see e.g. EP-A 461 502, DE-A 33 15 681, EP-A 291 797, WO-A 2013/007767). Intermediates (V) are preferably reacted with trimethylsulfoxonium- or trimethylsulfonium-salts, which might be prepared in situ, preferably trimethylsulfoxonium halides, trimethylsulfonium halides, trimethylsulfoxonium methylsulfates or trimethylsulfonium methylsulfates, preferably in the presence of a base such as sodium hydroxide. Epoxides (IX) can be subsequently reacted with a 1,2,4-triazole in order to obtain compounds (I-H). Preferably, this transformation is being conducted in the presence of a base, such as Na2CO3, K2CO3, Cs2CO3, NaOH, KOtBu, NaH or mixtures thereof, preferably in the presence of an organic solvent, such as tetrahydrofuran, dimethylformamide or toluene.
Process C (Scheme 3):
Epoxides of the general structure (IX) can be reacted with alcohols R2OH to yield alcohol (X). Preferentially, this transformation is being performed in the presence of an acid. Thereafter, alcohol (X) is being prepared for a nucleophilic substitution reaction. Along those lines, the alcohol functionality in compound (X) is being reacted with halogenating agents or sulfonating agents such as PBr3, PCl3, MeSO2Cl, tosyl chloride or thionyl chloride to obtain compounds (XI). Subsequently, Intermediates (XI) can be reacted with a 1,2,4-triazole in order to obtain compounds (I). Optionally, this transformation is being conducted in the presence of a base, such as Na2CO3, K2CO3, Cs2CO3, NaOH, KOtBu, NaH or mixtures thereof, preferably in the presence of an organic solvent, such as tetrahydrofuran, dimethylformamide or toluene.
Process D (Scheme 4):
Compounds (III) (Scheme 4) can be converted by means of methods described in the literature to the corresponding compounds (XII) and subsequently to compounds (XIII), (XIV), (XV), (XVI) and (V). Alternatively, one or several reaction steps might be skipped. This is particularly true if certain protecting groups are not essential and thus process D might be shortened (e.g. (XII)-(XV)).
Compounds (II), wherein X stands for F or Cl and Z stands for Cl, Br or I, are optionally reacted with carbon dioxide or formate salts to obtain compounds (XII). This transformation is performed in the presence of reagents or catalysts such as lithium, magnesium, n-butyllithium, methyllithium or nickel (e.g. Organic & Biomolecular Chemistry, 8(7), 1688-1694; 2010; WO-A 2003/033504; Organometallics, 13(11), 4645-7; 1994 and references cited therein). Alternatively, compound (III) is reacted in a hydroxycarbonylation reaction with carbon monoxide or a formate salt, preferentially in the presence of a catalyst such as Pd(OAc)2 and Co(OAc)2 (e.g. Dalton Transactions, 40(29), 7632-7638; 2011; Synlett, (11), 1663-1666; 2006 and references cited therein).
Subsequently, acids (XII) are reacted with anhydrides R5O—C(═O)—OR5, alcohols HO—R5 or alkyl halides Z—R5 in order to obtain ester of the general structure (XIII) (e.g. Russian Journal of General Chemistry, 70 (9), 1371-1377, 2000; Bulletin of the Chemical Society of Japan 76 (8), 1645-1667, 2003). The reactions are preferentially performed in the presence of a coupling reagent such as CDI or DEAD and/or a base such as triethylamine or DMAP. Optionally, the corresponding acid chlorides are being formed before the reaction with alcohols HO—R5 takes place (e.g. WO-A 2007/059265). Ester (XIII) are subsequently reacted with Phenols (II), optionally in the presence of a base such as K2CO3, Cs2CO3, NEt3 or DABCO and a solvent such as DMF, to obtain compounds (XIV). The following hydrolysis can be carried out in the presence of an acid such as H2SO4, HNO3 or p-toluenesulfonic acid or in the presence of a base such as KOH to yield acid (XV). Thereafter, acid (XV) can be reacted with alkoxyalkylamine, preferentially methoxymethylamine. The corresponding reaction can be carried out in the presence of reagents such as carbodiimides (e.g. WO-A 2011/076744), diimidazolyl ketone CDI, N-alkoxy-N-alkylcarbamoyl chlorides (e.g. Bulletin of the Korean Chemical Society 2002, 23, 521-524), S,S-di-2-pyridyl dithiocarbonates (e.g. Bulletin of the Korean Chemical Society 2001, 22, 421-423), trichloromethyl chloroformate (e.g. Synthetic communications 2003, 33, 4013-4018) or peptide coupling reagent HATU. Intermediates (V) can be obtained after reaction of Weinreb amides (XVI) with magnesium halides R1MgZ such as methylmagnesium bromide, methylmagnesium chloride or ethylmagnesiumbromide, preferentially in a solvent such as THF.
Process E (Scheme 5):

The invention therefore also relates to curative and protective methods for controlling phytopathogenic fungi by the use of the inventive active ingredients or compositions, which are applied to the seed, the plant or plant parts, the fruit or the soil in which the plants grow.
The fact that the active ingredients 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.
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, corms and rhizomes are listed. Crops and vegetative and generative propagating material, for example cuttings, corms, rhizomes, runners and seeds also belong to plant parts.
The inventive active ingredients, when they are well tolerated by plants, have favourable homeotherm toxicity and are well tolerated by the environment, are suitable for protecting plants and plant organs, for enhancing harvest yields, 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.
Plants which can be treated in accordance with the invention include the following main crop plants: maize, soya bean, alfalfa, cotton, sunflower, Brassica oil seeds such as Brassica napus (e.g. canola, rapeseed), Brassica rapa, B. juncea (e.g. (field) mustard) and Brassica carinata, Arecaceae sp. (e.g. oilpalm, coconut), rice, wheat, sugar beet, sugar cane, oats, rye, barley, millet and sorghum, triticale, flax, nuts, grapes and vine and various fruit and vegetables from various botanic taxa, e.g. Rosaceae sp.

(e.g. cannabis), Malvaceae sp. (e.g. okra, cocoa), Papaveraceae (e.g. poppy), Asparagaceae (e.g. asparagus); useful plants and ornamental plants in the garden and woods including turf, lawn, grass and Stevia rebaudiana; and in each case genetically modified types of these plants.
Plant Growth Regulation
In some cases, the inventive compounds can, at particular concentrations or application rates, also be used as herbicides, safeners, growth regulators or agents to improve plant properties, or as microbicides, for example as fungicides, antimycotics, bactericides, viricides (including compositions against viroids) or as compositions against MLO (Mycoplasma-like organisms) and RLO (Rickettsia-like organisms). If appropriate, they can also be used as intermediates or precursors for the synthesis of other active ingredients.
The inventive active ingredients intervene in the metabolism of the plants and can therefore also be used as growth regulators.
Plant growth regulators may exert various effects on plants. The effect of the substances depends essentially on the time of application in relation to the developmental stage of the plant, and also on the amounts of active ingredient applied to the plants or their environment and on the type of application. In each case, growth regulators should have a particular desired effect on the crop plants.
Plant growth-regulating compounds can be used, for example, to inhibit the vegetative growth of the plants. Such inhibition of growth is of economic interest, for example, in the case of grasses, since it is thus possible to reduce the frequency of grass cutting in ornamental gardens, parks and sport facilities, on roadsides, at airports or in fruit crops. Also of significance is the inhibition of the growth of herbaceous and woody plants on roadsides and in the vicinity of pipelines or overhead cables, or quite generally in areas where vigorous plant growth is unwanted.
Also important is the use of growth regulators for inhibition of the longitudinal growth of cereal. This reduces or completely eliminates the risk of lodging of the plants prior to harvest. In addition, growth regulators in the case of cereals can strengthen the culn, which also counteracts lodging. The employment of growth regulators for shortening and strengthening culms allows the deployment of higher fertilizer volumes to increase the yield, without any risk of lodging of the cereal crop.
In many crop plants, inhibition of vegetative growth allows denser planting, and it is thus possible to achieve higher yields based on the soil surface. Another advantage of the smaller plants obtained in this way is that the crop is easier to cultivate and harvest.
Inhibition of the vegetative plant growth may also lead to enhanced yields because the nutrients and assimilates are of more benefit to flower and fruit formation than to the vegetative parts of the plants.
Frequently, growth regulators can also be used to promote vegetative growth. This is of great benefit when harvesting the vegetative plant parts. However, promoting vegetative growth may also promote generative growth in that more assimilates are formed, resulting in more or larger fruits.
In some cases, yield increases may be achieved by manipulating the metabolism of the plant, without any detectable changes in vegetative growth. In addition, growth regulators can be used to alter the composition of the plants, which in turn may result in an improvement in quality of the harvested products. For example, it is possible to increase the sugar content in sugar beet, sugar cane, pineapples and in citrus fruit, or to increase the protein content in soya or cereals. It is also possible, for example, to use growth regulators to inhibit the degradation of desirable ingredients, for example sugar in sugar beet or sugar cane, before or after harvest. It is also possible to positively influence the production or the elimination of secondary plant ingredients. One example is the stimulation of the flow of latex in rubber trees.
Under the influence of growth regulators, parthenocarpic fruits may be formed. In addition, it is possible to influence the sex of the flowers. It is also possible to produce sterile pollen, which is of great importance in the breeding and production of hybrid seed.
Use of growth regulators can control the branching of the plants. On the one hand, by breaking apical dominance, it is possible to promote the development of side shoots, which may be highly desirable particularly in the cultivation of ornamental plants, also in combination with an inhibition of growth. On the other hand, however, it is also possible to inhibit the growth of the side shoots. This effect is of particular interest, for example, in the cultivation of tobacco or in the cultivation of tomatoes.
Under the influence of growth regulators, the amount of leaves on the plants can be controlled such that defoliation of the plants is achieved at a desired time. Such defoliation plays a major role in the mechanical harvesting of cotton, but is also of interest for facilitating harvesting in other crops, for example in viticulture. Defoliation of the plants can also be undertaken to lower the transpiration of the plants before they are transplanted.
Growth regulators can likewise be used to regulate fruit dehiscence. On the one hand, it is possible to prevent premature fruit dehiscence. On the other hand, it is also possible to promote fruit dehiscence or even flower abortion to achieve a desired mass (“thinning”), in order to eliminate alternation. Alternation is understood to mean the characteristic of some fruit species, for endogenous reasons, to deliver very different yields from year to year. Finally, it is possible to use growth regulators at the time of harvest to reduce the forces required to detach the fruits, in order to allow mechanical harvesting or to facilitate manual harvesting.
Growth regulators can also be used to achieve faster or else delayed ripening of the harvested material before or after harvest. This is particularly advantageous as it allows optimal adjustment to the requirements of the market. Moreover, growth regulators in some cases can improve the fruit colour. In addition, growth regulators can also be used to concentrate maturation within a certain period of time. This establishes the prerequisites for complete mechanical or manual harvesting in a single operation, for example in the case of tobacco, tomatoes or coffee.
By using growth regulators, it is additionally possible to influence the resting of seed or buds of the plants, such that plants such as pineapple or ornamental plants in nurseries, for example, germinate, sprout or flower at a time when they are normally not inclined to do so. In areas where there is a risk of frost, it may be desirable to delay budding or germination of seeds with the aid of growth regulators, in order to avoid damage resulting from late frosts.
Finally, growth regulators can induce resistance of the plants to frost, drought or high salinity of the soil. This allows the cultivation of plants in regions which are normally unsuitable for this purpose.
Resistance Induction/Plant Health and Other Effects
The active compounds according to the invention also exhibit 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 are to be understood as meaning, in the present context, those substances which are 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.
The active compounds according to the invention are also suitable for increasing the yield of crops. In addition, they show reduced toxicity and are well tolerated by plants.

further comprising improved marketability relating to improved fruit/grain quality, size distribution (kernel, fruit, etc.), increased storage/shelf-life, firmness/softness, taste (aroma, texture, etc.), grade (size, shape, number of berries, etc.), number of berries/fruits per bunch, crispness, freshness, coverage with wax, frequency of physiological disorders, colour, etc.;
further comprising increased desired ingredients such as e.g. protein content, fatty acids, oil content, oil quality, aminoacid composition, sugar content, acid content (pH), sugar/acid ratio (Brix), polyphenols, starch content, nutritional quality, gluten content/index, energy content, taste, etc.;
and further comprising decreased undesired ingredients such as e.g. less mycotoxines, less aflatoxines, geosmin level, phenolic aromas, lacchase, polyphenol oxidases and peroxidases, nitrate content etc.
Sustainable agriculture, comprising nutrient use efficiency, especially nitrogen (N)-use efficiency, phosphours (P)-use efficiency, water use efficiency, improved transpiration, respiration and/or CO2 assimilation rate, better nodulation, improved Ca-metabolism etc.
Delayed senescence, comprising improvement of plant physiology which is manifested, for example, in a longer grain filling phase, leading to higher yield, a longer duration of green leaf colouration of the plant and thus comprising colour (greening), water content, dryness etc. Accordingly, in the context of the present invention, it has been found that the specific inventive application of the active compound combination makes it possible to prolong the green leaf area duration, which delays the maturation (senescence) of the plant. The main advantage to the farmer is a longer grain filling phase leading to higher yield. There is also an advantage to the farmer on the basis of greater flexibility in the harvesting time.
Therein “sedimentation value” is a measure for protein quality and describes according to Zeleny (Zeleny value) the degree of sedimentation of flour suspended in a lactic acid solution during a standard time interval. This is taken as a measure of the baking quality. Swelling of the gluten fraction of flour in lactic acid solution affects the rate of sedimentation of a flour suspension. Both a higher gluten content and a better gluten quality give rise to slower sedimentation and higher Zeleny test values. The sedimentation value of flour depends on the wheat protein composition and is mostly correlated to the protein content, the wheat hardness, and the volume of pan and hearth loaves. A stronger correlation between loaf volume and Zeleny sedimentation volume compared to SDS sedimentation volume could be due to the protein content influencing both the volume and Zeleny value (Czech J. Food Sci. Vol. 21, No. 3: 91-96, 2000).
Further the “falling number” as mentioned herein is a measure for the baking quality of cereals, especially of wheat. The falling number test indicates that sprout damage may have occurred. It means that changes to the physical properties of the starch portion of the wheat kernel has already happened. Therein, the falling number instrument analyzes viscosity by measuring the resistance of a flour and water paste to a falling plunger. The time (in seconds) for this to happen is known as the falling number. The falling number results are recorded as an index of enzyme activity in a wheat or flour sample and results are expressed in time as seconds. A high falling number (for example, above 300 seconds) indicates minimal enzyme activity and sound quality wheat or flour. A low falling number (for example, below 250 seconds) indicates substantial enzyme activity and sprout-damaged wheat or flour.
The term “more developed root system”/“improved root growth” refers to longer root system, deeper root growth, faster root growth, higher root dry/fresh weight, higher root volume, larger root surface area, bigger root diameter, higher root stability, more root branching, higher number of root hairs, and/or more root tips and can be measured by analyzing the root architecture with suitable methodologies and Image analysis programmes (e.g. WinRhizo).
The term “crop water use efficiency” refers technically to the mass of agriculture produce per unit water consumed and economically to the value of product(s) produced per unit water volume consumed and can e.g. be measured in terms of yield per ha, biomass of the plants, thousand-kernel mass, and the number of ears per m2.
The term “nitrogen-use efficiency” refers technically to the mass of agriculture produce per unit nitrogen consumed and economically to the value of product(s) produced per unit nitrogen consumed, reflecting uptake and utilization efficiency.
Improvement in greening/improved colour and improved photosynthetic efficiency as well as the delay of senescence can be measured with well-known techniques such as a HandyPea system (Hansatech). Fv/Fm is a parameter widely used to indicate the maximum quantum efficiency of photosystem II (PSII). This parameter is widely considered to be a selective indication of plant photosynthetic performance with healthy samples typically achieving a maximum Fv/Fm value of approx. 0.85. Values lower than this will be observed if a sample has been exposed to some type of biotic or abiotic stress factor which has reduced the capacity for photochemical quenching of energy within PSII. Fv/Fm is presented as a ratio of variable fluorescence (Fv) over the maximum fluorescence value (Fm). The Performance Index is essentially an indicator of sample vitality. (See e.g. Advanced Techniques in Soil Microbiology, 2007, 11, 319-341; Applied Soil Ecology, 2000, 15, 169-182.)
The improvement in greening/improved colour and improved photosynthetic efficiency as well as the delay of senescence can also be assessed by measurement of the net photosynthetic rate (Pn), measurement of the chlorophyll content, e.g. by the pigment extraction method of Ziegler and Ehle, measurement of the photochemical efficiency (Fv/Fm ratio), determination of shoot growth and final root and/or canopy biomass, determination of tiller density as well as of root mortality.
Within the context of the present invention preference is given to improving plant physiology effects which are selected from the group comprising: enhanced root growth/more developed root system, improved greening, improved water use efficiency (correlating to reduced water consumption), improved nutrient use efficiency, comprising especially improved nitrogen (N)-use efficiency, delayed senescence and enhanced yield.
Within the enhancement of yield preference is given as to an improvement in the sedimentation value and the falling number as well as to the improvement of the protein and sugar content—especially with plants selected from the group of cereals (preferably wheat).
Preferably the novel use of the fungicidal compositions of the present invention relates to a combined use of a) preventively and/or curatively controlling pathogenic fungi and/or nematodes, with or without resistance management, and b) at least one of enhanced root growth, improved greening, improved water use efficiency, delayed senescence and enhanced yield. From group b) enhancement of root system, water use efficiency and N-use efficiency is particularly preferred.
Seed Treatment
The invention further comprises a method for treating seed.
The invention further relates to seed which has been treated by one of the methods described in the previous paragraph. The inventive seeds are employed in methods for the protection of seed from harmful microorganisms. In these methods, seed treated with at least one inventive active ingredient is used.
The inventive active ingredients or compositions are 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, and also during and after 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 so as to provide the best possible protection for the seed and the germinating plant from 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.
The present invention therefore also relates to a method for protection of seed and germinating plants from attack by phytopathogenic fungi, by treating the seed with an inventive composition. The invention likewise relates to the use of the inventive compositions for treatment of seed to protect the seed and the germinating plant from phytopathogenic fungi. The invention further relates to seed which has been treated with an inventive composition for protection from phytopathogenic fungi.
The control of phytopathogenic fungi which damage plants post-emergence is effected 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 the particular systemic properties of the inventive active ingredients and compositions mean that treatment of the seed with these active ingredients and compositions not only protects the seed itself, but also the resulting plants after emergence, from phytopathogenic fungi. In this way, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.
It is likewise considered to be advantageous that the inventive active ingredients or compositions can especially also be used with transgenic seed, in which case the plant growing from this seed is capable of expressing a protein which acts against pests. By virtue of the treatment of such seed with the inventive active ingredients or compositions, merely the expression of the protein, for example an insecticidal protein, can control certain pests. Surprisingly, a further synergistic effect can be observed in this case, which additionally increases the effectiveness for protection against attack by pests.
The inventive compositions are suitable for protecting seed of any plant variety which is used in agriculture, in greenhouses, in forests or in horticulture and viticulture. In particular, this is the seed of cereals (such as wheat, barley, rye, triticale, sorghum/millet and oats), maize, cotton, soya beans, rice, potatoes, 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 the seed of cereals (such as wheat, barley, rye, triticale and oats), maize and rice is of particular significance.
As also described below, the treatment of transgenic seed with the inventive active ingredients or compositions is of particular significance. This relates to the seed of plants containing at least one heterologous gene. Definition and examples of suitable heterologous genes are given below.
In the context of the present invention, the inventive 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.
When treating the seed, care must generally be taken that the amount of the inventive composition applied to the seed and/or the amount of further additives is selected such that the germination of the seed is not impaired, or that the resulting plant is not damaged. This has to be borne in mind in particular in the case of active ingredients which can have phytotoxic effects at certain application rates.
The inventive compositions can be applied directly, i.e. without containing any other components and without having been diluted. In general, it is preferable to apply the compositions to the seed in the form of a suitable formulation. Suitable formulations and methods for seed treatment are known to those skilled in the art and are described, for example, in the following documents: U.S. Pat. Nos. 4,272,417, 4,245,432, 4,808,430, 5,876,739, US 2003/0176428 A1, WO 2002/080675, WO 2002/028186.
The active ingredients usable in accordance with the invention can be converted to the customary seed dressing formulations, such as solutions, emulsions, suspensions, powders, foams, slurries or other coating compositions for seed, and also ULV formulations.
These formulations are prepared in a known manner, by mixing the active ingredients with customary additives, for example customary extenders and also solvents or diluents, dyes, wetting agents, dispersants, emulsifiers, antifoams, preservatives, secondary thickeners, adhesives, gibberellins and also water.
Useful dyes which may be present in the seed dressing formulations usable in accordance with the invention are all dyes which are customary for such purposes. It is possible to use either pigments, which are sparingly soluble in water, or dyes, which are soluble in water. Examples include the dyes known by the names Rhodamine B, C.I. Pigment Red 112 and C.I. Solvent Red 1.
Useful wetting agents which may be present in the seed dressing formulations usable in accordance with the invention are all substances which promote wetting and which are conventionally used for the formulation of active agrochemical ingredients. Preference is given to using alkyl naphthalenesulphonates, such as diisopropyl or diisobutyl naphthalenesulphonates.
Useful dispersants and/or emulsifiers which may be present in the seed dressing formulations usable in accordance with the invention are all nonionic, anionic and cationic dispersants conventionally used for the formulation of active agrochemical ingredients. Usable with preference are nonionic or anionic dispersants or mixtures of nonionic or anionic dispersants. Suitable nonionic dispersants include especially ethylene oxide/propylene oxide block polymers, alkylphenol polyglycol ethers and tristryrylphenol polyglycol ether, and the phosphated or sulphated derivatives thereof. Suitable anionic dispersants are especially lignosulphonates, polyacrylic acid salts and arylsulphonate/formaldehyde condensates.
Antifoams which may be present in the seed dressing formulations usable in accordance with the invention are all foam-inhibiting substances conventionally used for the formulation of active agrochemical ingredients. Silicone antifoams and magnesium stearate can be used with preference.
Preservatives which may be present in the seed dressing formulations usable in accordance with the invention are all substances usable for such purposes in agrochemical compositions. Examples include dichlorophene and benzyl alcohol hemiformal.
Secondary thickeners which may be present in the seed dressing formulations usable in accordance with the invention are all substances usable for such purposes in agrochemical compositions. Preferred examples include cellulose derivatives, acrylic acid derivatives, xanthan, modified clays and finely divided silica.
Adhesives which may be present in the seed dressing formulations usable in accordance with the invention are all customary binders usable in seed dressing products. Preferred examples include polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and tylose.
The gibberellins which may be present in the seed dressing formulations usable in accordance with the invention may preferably be gibberellins A1, A3 (=gibberellic acid), A4 and A7; particular preference is given to using gibberellic acid. The gibberellins are known (cf. R. Wegler “Chemie der Pflanzenschutz- und Schäidlingsbekämpfungsmittel” [Chemistry of the Crop Protection Compositions and Pesticides], vol. 2, Springer Verlag, 1970, p. 401-412).
The seed dressing formulations usable in accordance with the invention can be used, either directly or after previously having been diluted with water, for the treatment of a wide range of different seed, including the seed of transgenic plants. In this case, additional synergistic effects may also occur in interaction with the substances formed by expression.
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.
Mycotoxins
In addition, the inventive treatment 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. crookwellense, F. culmorum, F. graminearum (Gibberella zeae), F. equiseti, F. fijikoroi, F. musarum, F. oxysporum, F. proliferatum, F. poae, F. pseudograminearum, 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. flavus, 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, Stachybotrys spec. and others.
Material Protection
The inventive active ingredients or compositions can also be used in the protection of materials, for protection of industrial materials against attack and destruction by harmful microorganisms, for example fungi and insects.
In addition, the inventive compounds can be used as antifouling compositions, alone or in combinations with other active ingredients.
Industrial materials in the present context are understood to mean inanimate materials which have been prepared for use in industry. For example, industrial materials which are to be protected by inventive active ingredients from microbial alteration or destruction may be adhesives, glues, paper, wallpaper and board/cardboard, textiles, carpets, leather, wood, fibers and tissues, paints and plastic articles, cooling lubricants and other materials which can be infected with or destroyed by microorganisms. Parts of production plants and buildings, for example cooling-water circuits, cooling and heating systems and ventilation and air-conditioning units, which may be impaired by the proliferation of microorganisms may also be mentioned within the scope of the materials to be protected. Industrial materials within the scope of the present invention preferably include adhesives, sizes, paper and card, leather, wood, paints, cooling lubricants and heat transfer fluids, more preferably wood.
The inventive active ingredients or compositions may prevent adverse effects, such as rotting, decay, discoloration, decoloration or formation of mould.
In the case of treatment of wood the compounds/compositions according to the invention may also be used against fungal diseases liable to grow on or inside timber. The term “timber” means all types of species of wood, and all types of working of this wood intended for construction, for example solid wood, high-density wood, laminated wood, and plywood. The method for treating timber according to the invention mainly consists in contacting one or more compounds according to the invention or a composition according to the invention; this includes for example direct application, spraying, dipping, injection or any other suitable means.
In addition, the inventive compounds can be used to protect objects which come into contact with saltwater or brackish water, especially hulls, screens, nets, buildings, moorings and signalling systems, from fouling.
The inventive method for controlling unwanted fungi can also be employed for protecting storage goods. Storage goods are understood to mean natural substances of vegetable or animal origin or processed products thereof which are of natural origin, and for which long-term protection is desired. Storage goods of vegetable origin, for example plants or plant parts, such as stems, leaves, tubers, seeds, fruits, grains, can be protected freshly harvested or after processing by (pre)drying, moistening, comminuting, grinding, pressing or roasting. Storage goods also include timber, both unprocessed, such as construction timber, electricity poles and barriers, or in the form of finished products, such as furniture. Storage goods of animal origin are, for example, hides, leather, furs and hairs. The inventive active ingredients may prevent adverse effects, such as rotting, decay, discoloration, decoloration or formation of mould.
Microorganisms capable of degrading or altering the industrial materials include, for example, bacteria, fungi, yeasts, algae and slime organisms. The inventive active ingredients preferably act against fungi, especially moulds, wood-discoloring and wood-destroying fungi (Ascomycetes, Basidiomycetes, Deuteromycetes and Zygomycetes), and against slime organisms and algae. Examples include microorganisms of the following genera: Alternaria, such as Alternaria tenuis; Aspergillus, such as Aspergillus niger; Chaetomium, such as Chaetomium globosum; Coniophora, such as Coniophora puetana; Lentinus, such as Lentinus tigrinus; Penicillium, such as Penicillium glaucum; Polyporus, such as Polyporus versicolor; Aureobasidium, such as Aureobasidium pullulans; Sclerophoma, such as Sclerophoma pityophila; Trichoderma, such as Trichoderma viride; Ophiostoma spp., Ceratocystis spp., Humicola spp., Petriella spp., Trichurus spp., Coriolus spp., Gloeophyllum spp., Pleurotus spp., Poria spp., Serpula spp. and Tyromyces spp., Cladosporium spp., Paecilomyces spp. Mucor spp., Escherichia, such as Escherichia coli; Pseudomonas, such as Pseudomonas aeruginosa; Staphylococcus, such as Staphylococcus aureus, Candida spp. and Saccharomyces spp., such as Saccharomyces cerevisae.
Antimycotic Activity
In addition, the inventive active ingredients also have very good antimycotic activity. They have a very broad antimycotic activity spectrum, especially against dermatophytes and yeasts, moulds and diphasic fungi (for example against Candida species, such as C. albicans, C. glabrata), and Epidermophyton floccosum, Aspergillus species, such as A. niger and A. fumigatus, Trichophyton species, such as T. mentagrophytes, Microsporon species such as M. canis and M. audouinii. The list of these fungi by no means constitutes a restriction of the mycotic spectrum covered, and is merely of illustrative character.
The inventive active ingredients can therefore be used both in medical and in non-medical applications.
GMO
As already mentioned above, it is possible to treat all plants and their parts in accordance with the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and also parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The terms “parts” or “parts of plants” or “plant parts” have been explained above. More preferably, plants of the plant cultivars which are commercially available or are in use are treated in accordance with the invention. 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.
The method of treatment according to the invention can be used in the treatment of genetically modified organisms (GMOs), e.g. plants or seeds. Genetically modified plants (or transgenic plants) are plants of which a heterologous gene has been stably integrated into genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating 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 that is 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.
Plants and plant cultivars which are preferably to be treated according to the invention include all plants which have genetic material which impart particularly advantageous, useful traits to these plants (whether obtained by breeding and/or biotechnological means).
Plants and plant cultivars which are also preferably to be treated according to the invention are resistant against one or more biotic stresses, i.e. said plants show a better defense against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
Plants and plant cultivars which may also be treated according to the invention are those plants which are resistant to one or more abiotic stresses. Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, flooding, increased soil salinity, increased mineral exposure, ozone exposure, high light exposure, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients, shade avoidance.
Plants and plant cultivars which may also be treated according to the invention, are those plants characterized by enhanced yield characteristics. Increased yield in said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can furthermore be affected by improved plant architecture (under stress and non-stress conditions), including but not limited to, early flowering, flowering control for hybrid seed production, seedling vigor, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content and composition for example cotton or starch, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processability and better storage stability.
Plants that may be treated according to the invention are hybrid plants that already express the characteristic of heterosis or hybrid vigor which results in generally higher yield, vigor, health and resistance towards biotic and abiotic stresses).
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are insect-resistant transgenic plants, i.e. plants made resistant to attack by certain target insects. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such insect resistance.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are tolerant to abiotic stresses. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention show altered quantity, quality and/or storage-stability of the harvested product and/or altered properties of specific ingredients of the harvested product.
Plants or plant cultivars (that can be obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as cotton plants, with altered fiber characteristics. Such plants can be obtained by genetic transformation, or by selection of plants contain a mutation imparting such altered fiber characteristics.
Plants or plant cultivars (that can be obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as oilseed rape or related Brassica plants, with altered oil profile characteristics. Such plants can be obtained by genetic transformation, or by selection of plants contain a mutation imparting such altered oil profile characteristics.
Plants or plant cultivars (that can be obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as oilseed rape or related Brassica plants, with altered seed shattering characteristics. Such plants can be obtained by genetic transformation, or by selection of plants contain a mutation imparting such altered seed shattering characteristics and include plants such as oilseed rape plants with delayed or reduced seed shattering.
Plants or plant cultivars (that can be obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as Tobacco plants, with altered post-translational protein modification patterns.
Application Rates and Timing
When using the inventive active ingredients as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. The application rate of the inventive active ingredients is in the case of treatment of plant parts, for example leaves: from 0.1 to 10 000 g/ha, preferably from 10 to 1000 g/ha, more preferably from 10 to 800 g/ha, even more preferably from 50 to 300 g/ha (in the case of application by watering or dripping, it is even possible to reduce the application rate, especially when inert substrates such as rockwool or perlite are used);
in the case of seed treatment: from 2 to 200 g per 100 kg of seed, preferably from 3 to 150 g per 100 kg of seed, more preferably from 2.5 to 25 g per 100 kg of seed, even more preferably from 2.5 to 12.5 g per 100 kg of seed;
in the case of soil treatment: from 0.1 to 10 000 g/ha, preferably from 1 to 5000 g/ha.
These application rates are merely by way of example and are not limiting for the purposes of the invention.
The inventive active ingredients or compositions comprising a compound according to formula (I) can thus be used to protect plants from attack by the pathogens mentioned for a certain period of time after treatment. The period for which protection is provided extends generally for 1 to 28 days, preferably for 1 to 14 days, more preferably for 1 to 10 days, most preferably for 1 to 7 days, after the treatment of the plants with the active ingredients, or for up to 200 days after a seed treatment.
The plants listed can particularly advantageously be treated in accordance with the invention with the compounds of the general formula (I) and the inventive compositions. The preferred ranges stated above for the active ingredients or compositions also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or compositions specifically mentioned in the present text.
The invention is illustrated by the examples below. However, the invention is not limited to the examples.

The following tables illustrate in a non-limiting manner examples of compounds according to the invention.
Log P Values:
Measurement of Log P values was performed according to EEC directive 79/831 Annex V.A8 by HPLC (High Performance Liquid Chromatography) on reversed phase columns with the following methods:
If more than one Log P value is available within the same method, all the values are given and separated by “+”.
Calibration was done with straight-chain alkan2-ones (with 3 to 16 carbon atoms) with known Log P values (measurement of Log P values using retention times with linear interpolation between successive alkanones). Lambda-max-values were determined using UV-spectra from 200 nm to 400 nm and the peak values of the chromatographic signals.
NMR-Peak lists
1H-NMR data of selected examples are written below in form of 1H-NMR-peak lists. To each signal peak are listed the δ-value in ppm and the signal intensity in round brackets. Between the δ-value—signal intensity pairs are semicolons as delimiters.
The peak list of an example has therefore the form:
δ1 (intensity1); δ2 (intensity2); . . . ; δi (intensityi); . . . δn (intensityn)
Intensity of sharp signals correlates with the height of the signals in a printed example of a NMR spectrum in cm and shows the real relations of signal intensities. From broad signals several peaks or the middle of the signal and their relative intensity in comparison to the most intensive signal in the spectrum can be shown.
For calibrating chemical shift for 1H spectra, we use tetramethylsilane and/or the chemical shift of the solvent used, especially in the case of spectra measured in DMSO. Therefore in NMR peak lists, tetramethylsilane peak can occur but not necessarily.
The 1H-NMR peak lists are similar to classical 1H-NMR prints and contains therefore usually all peaks, which are listed at classical NMR-interpretation.
Additionally they can show like classical 1H-NMR prints signals of solvents, stereoisomers of the target compounds, which are also object of the invention, and/or peaks of impurities.
To show compound signals in the delta-range of solvents and/or water the usual peaks of solvents, for example peaks of DMSO in DMSO-D6 and the peak of water are shown in our 1H-NMR peak lists and have usually on average a high intensity.
The peaks of stereoisomers of the target compounds and/or peaks of impurities have usually on average a lower intensity than the peaks of target compounds (for example with a purity >90%).
Such stereoisomers and/or impurities can be typical for the specific preparation process. Therefore their peaks can help to recognize the reproduction of our preparation process via “side-products-fingerprints”.
An expert, who calculates the peaks of the target compounds with known methods (MestreC, ACD-simulation, but also with empirically evaluated expectation values) can isolate the peaks of the target compounds as needed optionally using additional intensity filters. This isolation would be similar to relevant peak picking at classical 1H-NMR interpretation.
Further details of NMR-data description with peak lists you find in the publication “Citation of NMR Peaklist Data within Patent Applications” of the Research Disclosure Database Number 564025.
