The present invention relates to novel triazole compounds of the formulae I and II as defined below which carry a sulfur substituent, to agricultural compositions containing them, to their use as fungicides and to intermediate compounds used in the method of producing them.
The control of plant diseases caused by phythopathogenic fungi is extremely important for achieving high crop efficiency. Plant disease damage to ornamental, vegetable, field, cereal, and fruit crops can cause significant reduction in productivity and thereby result in increased costs to the consumer.
DE 19528046, DE 19617461, DE 19617282, DE 19620407, DE 19620590, WO96/16048 and WO 97/43269 describe sulfurized triazolyl derivatives. The compounds are used for combating harmful fungi.
There is a continuous need for new compounds which are more effective, less costly, less toxic, environmentally safer and/or have different modes of action.
Accordingly, it is an object of the present invention to provide compounds having a better fungicidal activity and/or a better crop plant compatibility.
Surprisingly, these objects are achieved by triazole compounds of the general formulae I and II, defined below, and by the agriculturally acceptable salts of the compounds I and II.
Accordingly, the present invention relates to triazole compounds of the formulae I and II and to agriculturally useful salts thereof
wherein
R6 is selected from hydrogen, C1-C10-alkyl, C2-C10-alkenyl, C2-C10-haloalkenyl, C2-C10-alkynyl, C2-C10-haloalkynyl, C3-C10-cycloalkyl, C3-C10-halocycloalkyl, phenyl, phenyl-C1-C4-alkyl, where the phenyl moiety in the 2 last-mentioned radicals may carry 1, 2, 3, 4 or 5 substituents R11, and a 5- or 6-membered saturated, partially unsaturated or aromatic heterocyclic ring containing 1, 2 or 3 heteroatoms selected from N, O and S as ring members, where the heterocyclic ring may carry 1, 2 or 3 substituents R11; or, in case m is 0, may also be selected from —C(═O)R12, —C(═S)R12, —S(O)2R12, —CN, —P(=Q)R13R14; M and a group of the formula III
The present invention also provides the use of triazole compounds of the formulae I and II and/or their agriculturally useful salts for controlling harmful fungi.
The invention further provides fungicidal compositions comprising these triazole compounds of the formulae I and/or II (and/or also of the formula IV; see below) and/or their agriculturally acceptable salts and suitable carriers. Suitable agriculturally acceptable carriers are described below.
The compounds I and II can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. The compounds of the invention may be present as a mixture of stereoisomers, e.g. a racemate, individual stereoisomers, or as an optically active form.
Compounds I and II can be understood as positional/double bond isomers of each other, at least in case the radicals R6/R6a are identical. In case R6 (and of course also R6a) is hydrogen, the respective compounds I and II are tautomers.
Suitable agriculturally useful salts are especially the salts of those cations or the acid addition salts of those acids whose cations and anions, respectively, have no adverse effect on the fungicidal action of the compounds I and II. Thus, suitable cations are in particular the ions of the alkali metals, preferably sodium and potassium, of the alkaline earth metals, preferably calcium, magnesium and barium, and of the transition metals, preferably manganese, copper, zinc and iron, and also the ammonium ion which, if desired, may carry one to four C1-C4-alkyl substituents and/or one phenyl or benzyl substituent, preferably diisopropylammonium, tetramethylammonium, tetrabutylammonium, trimethylbenzylammonium, furthermore phosphonium ions, sulfonium ions, preferably tri(C1-C4-alkyl)sulfonium and sulfoxonium ions, preferably tri(C1-C4-alkyl)sulfoxonium.

Compounds of formulae I and II can be prepared by one or more of the following methods and variations as described in schemes 1 to 8 and in the syntheses descriptions below. The variables are as defined above for formulae I and II.
Compounds of formula I, wherein R6 is H and m is 0 (or compounds II, wherein R6a is H), can be prepared by sulfurizing the corresponding triazole derivative IV as outlined in scheme 1. Sulfurization can be carried out in analogy to known processes, for example as described in WO 96/16048. For instance, the triazolyl ring can be first deprotonated with a strong base, e.g. an organolithium base, such as n-butyllithium, tert-butyllithium or sec-butyllithium, lithium diisopropyl amide, sodium hydride, sodium amide or potassium tert-butylate mixed with tetramethylethylene diamine (TMEDA), and then the resulting anion is reacted with elemental sulfur. Sulfur is generally used in powdered form. The reaction is generally carried out in an inert solvent, such as ethers, e.g. diethylether, methyl-tert-butylether, tetrahydrofuran or dioxane, dimethoxyethane, liquid ammonia, dimethylsulfoxide or dimethylformamide. The reaction temperature is not very critical and can range, for example, from −70 to +50° C., preferably from −70 to 0° C. Alternatively, sulfurization can be carried out in the absence of a base by reacting 7 with elemental sulfur in a high-boiling solvent, such as N-methylpyrrolidinone, dioxane or N,N-dimethylformamide, while heating, e.g. to 160 to 250° C. After completion of the reaction, the resulting mixture is hydrolyzed, e.g. by the addition of water or an aqueous acid, such as a mineral acid (e.g. dilute sulfuric acid or hydrochloric acid), acetic acid or ammoniumchloride, to give compound I.
The triazole compound IV, wherein R2 is H, can be prepared in analogy to known methods, such as described, for example, in DE-A-3702301, as outlined in scheme 2. For instance, the oxirane compound 1 and [1,2,4]-1H-triazole can be reacted in the presence of a base, such as an alkali metal hydride (e.g. sodium hydride, potassium hydride), an alkali metal hydroxide (e.g. sodium hydroxide, potassium hydroxide), or an alkali metal carbonate (e.g. sodium carbonate, potassium carbonate, caesium carbonate).

For instance, the ketone 2 may be reacted with a sulfonium ylide or an oxosulfonium ylide, such as dimethyloxosulfonium methylide or dimethylsulfonium methylide in a solvent. Alternatively, the oxirane 1 can be prepared in an epoxidation reaction in analogy to the method described in Tetrahedron Lett. 23, 5283 (1982) or in EP-A-0655443 by subjecting 2 to the reaction with a trimethylsulfonium salt, such as trimethylsulfonium bromide, trimethylsulfonium iodide or methyltrimethylsulfonium sulfate, in the presence of a metal oxide, such as alkaline metal oxides (e.g. sodium oxide, potassium oxide), alkaline earth metal oxides (e.g. magnesium oxide, calcium oxide, barium oxide) or zinc oxide, and optionally a base, such as alkali metal hydrides (e.g. sodium hydride, potassium hydride), alkali metal hydroxides (e.g. sodium hydroxide, potassium hydroxide), alkali metal carbonates (e.g. sodium carbonate, potassium carbonate, caesium carbonate) in a two-phase solid/liquid system comprising an organic solvent, such as toluene, N-methypyrrolidinone, ethers (e.g. diethyl ether, tetrahydrofuran), acetonitrile or N,N-dimethylformamide.

The resulting triazolidinthione 9 is then oxidized using, for example, FeCl3 in an aqueous acid (e.g. hydrochloric acid) or oxygen in the presence of an alkali metal hydroxide (e.g. sodium hydroxide, potassium hydroxide) and elemental sulfur to I/II. In a yet further alternative, 7 is reacted with a dialkyl ketone (e.g. acetone, diethylketone, methyl ethyl ketone) and a thiocyanate (e.g. sodium thiocyanate, potassium thiocyanate, ammonium thiocyanate) in a solvent to give the triazolidinthione 10.

No. 6,222,100, WO 01/82685, WO 00/026390, WO 97/41218, WO 98/002526, WO 98/02527, WO 04/106529, WO 05/20673, WO 03/014357, WO 03/13225, WO 03/14356, WO 04/16073); enolpyruvylshikimate-3-phosphate synthase (EPSPS) inhibitors, such as glyphosate (see e.g. WO 92/00377); glutamine synthetase (GS) inhibitors, such as glufosinate (see e.g. EP-A 242 236, EP-A 242 246) or oxynil herbicides (see e.g. U.S. Pat.

Several cultivated plants have been rendered tolerant to herbicides by conventional methods of breeding (mutagenesis), e.g. Clearfield® summer rape (Canola, BASF SE, Germany) being tolerant to imidazolinones, e.g. imazamox. Genetic engineering methods have been used to render cultivated plants, such as soybean, cotton, corn, beets and rape, tolerant to herbicides such as glyphosate and glufosinate, some of which are commercially available under the trade names RoundupReady® (glyphosate-tolerant, Monsanto, U.S.A.) and LibertyLink® (glufosinatetolerant, Bayer CropScience, Germany).
Furthermore, plants are also covered that, by the use of recombinant DNA techniques, are capable to synthesize one or more insecticidal proteins, especially those known from the bacterial genus Bacillus, particularly from Bacillus thuringiensis, such as δ-endotoxins, e.g. CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIII B(b1) or Cry9c; vegetative insecticidal proteins (VIP), e.g. VIP1, VIP2, VIP3 or VIP3A; insecticidal proteins of bacteria colonizing nematodes, e.g. Photorhabdus spp. or Xenorhabdus spp.; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins, or other insect-specific neurotoxins; toxins produced by fungi, such Streptomycetes toxins, plant lectins, such as pea or barley lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin or papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroid oxidase, ecdysteroid-IDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors or HMG-CoA-reductase; ion channel blockers, such as blockers of sodium or calcium channels; juvenile hormone esterase; diuretic hormone receptors (helicokinin receptors); stilben synthase, bibenzyl synthase, chitinases or glucanases. In the context of the present invention these insecticidal proteins or toxins are to be understood expressly also as pre-toxins, hybrid proteins, truncated or otherwise modified proteins. Hybrid proteins are characterized by a new combination of protein domains, (see, e.g. WO 02/015701). Further examples of such toxins or genetically modified plants capable of synthesizing such toxins are disclosed, e.g., in EP-A 374 753, WO 93/007278, WO 95/34656, EP-A 427 529, EP-A 451 878, WO 03/18810 and WO 03/52073. The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e.g., in the publications mentioned above. These insecticidal proteins contained in the genetically modified plants impart to the plants producing these proteins tolerance to harmful pests from all taxonomic groups of arthropods, especially to beetles (Coleoptera), two-winged insects (Diptera), and moths (Lepidoptera) and to nematodes (Nematoda).

Furthermore, plants are also covered that, by the use of recombinant DNA techniques, are capable to synthesize one or more proteins to increase the resistance or tolerance of those plants to bacterial, viral or fungal pathogens. Examples of such proteins are the so-called “pathogenesis-related proteins” (PR proteins, see, e.g. EP-A 392 225), plant disease resistance genes (e.g. potato cultivars, which express resistance genes acting against Phytophthora infestans derived from the Mexican wild potato Solanum bulbocastanum) or T4-lysozym (e.g. potato cultivars capable of synthesizing these proteins with increased resistance against bacteria such as Erwinia amylvora). The methods for producing such genetically modified plants are generally known to the person skilled in the art and are described, e.g., in the publications mentioned above.
Furthermore, plants are also covered that, by the use of recombinant DNA techniques, are capable to synthesize one or more proteins to increase the productivity (e.g. bio mass production, grain yield, starch content, oil content or protein content), tolerance to drought, salinity or other growth-limiting environmental factors or tolerance to pests and fungal, bacterial or viral pathogens of those plants.
Furthermore, plants are also covered that, by the use of recombinant DNA techniques, contain a modified amount of substances of content or new substances of content, specifically to improve human or animal nutrition, e.g. oil crops that produce healthpromoting long-chain omega-3 fatty acids or unsaturated omega-9 fatty acids (e.g. Nexera® rape, DOW Agro Sciences, Canada).
Furthermore, plants are also covered that, by the use of recombinant DNA techniques, contain a modified amount of substances of content or new substances of content, specifically to improve raw material production, e.g. potatoes that produce increased amounts of amylopectin (e.g. Amflora® potato, BASF SE, Germany).

The invention also relates to a method for improving plant health by treating a plant, its propagation material and/or the locus where the plant is growing or is to grow with an effective amount of compounds I, II and/or IV and compositions thereof, respectively.
The term “plant health” is to be understood to denote a condition of the plant and/or its products which is determined by several indicators alone or in combination with each other such as yield (e.g. increased biomass and/or increased content of valuable ingredients), plant vigor [e.g. improved plant growth and/or greener leaves (“greening effect”)], quality (e.g. improved content or composition of certain ingredients) and tolerance to abiotic and/or biotic stress. The above identified indicators for the health condition of a plant may be interdependent or may result from each other.
The compounds of formula I, II and IV can be present in different crystal modifications whose biological activity may differ. They are likewise subject matter of the present invention.
The compounds I, II and IV are employed as such or in form of compositions by treating the fungi or the plants, plant propagation materials, such as seeds, soil, surfaces, materials or rooms to be protected from fungal attack with a fungicidally effective amount of the active substances. The application can be carried out both before and after the infection of the plants, plant propagation materials, such as seeds, soil, surfaces, materials or rooms by the fungi.
Plant propagation materials may be treated with compounds I, II and/or IV as such or a composition comprising at least one compound I, II and/or IV prophylactically either at or before planting or transplanting.
The invention also relates to agrochemical compositions comprising a solvent or solid carrier and at least one compound I, II and/or IV and to the use for controlling harmful fungi.
An agrochemical composition comprises a fungicidally effective amount of a compound I, II and/or IV. The term “effective amount” denotes an amount of the composition or of the compounds I, II and/or IV, which is sufficient for controlling harmful fungi on cultivated plants or in the protection of materials and which does not result in a substantial damage to the treated plants. Such an amount can vary in a broad range and is dependent on various factors, such as the fungal species to be controlled, the treated cultivated plant or material, the climatic conditions and the specific compound I used.
The compounds I, II and IV and salts thereof can be converted into customary types of agrochemical compositions, e.g. solutions, emulsions, suspensions, dusts, powders, pastes and granules. The composition type depends on the particular intended purpose; in each case, it should ensure a fine and uniform distribution of the compound according to the invention.
Examples for composition types are suspensions (SC, OD, FS), emulsifiable concentrates (EC), emulsions (EW, EO, ES), pastes, pastilles, wettable powders or dusts (WP, SP, SS, WS, DP, DS) or granules (GR, FG, GG, MG), which can be water-soluble or wettable, as well as gel formulations for the treatment of plant propagation materials such as seeds (GF).
Usually the composition types (e.g. SC, OD, FS, EC, WG, SG, WP, SP, SS, WS, GF) are employed diluted. Composition types such as DP, DS, GR, FG, GG and MG are usually used undiluted.

Amounts customarily applied in the protection of materials are, e.g., 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active substance per cubic meter of treated material.
Various types of oils, wetters, adjuvants, herbicides, bactericides, other fungicides and/or pesticides may be added to the active substances or the compositions comprising them, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the compositions according to the invention in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.
Adjuvants which can be used are in particular organic modified polysiloxanes such as Break Thru S 240®; alcohol alkoxylates such as Atplus 245®, Atplus MBA 1303®, Plurafac LF 300° and Lutensol ON 30®; EO/PO block polymers, e.g. Pluronic RPE 2035® and Genapol B®; alcohol ethoxylates such as Lutensol XP 80®; and dioctyl sulfosuccinate sodium such as Leophen RA®.

Those mixtures are of particular interest, since many of them at the same application rate show higher efficiencies against harmful fungi. Furthermore, combating harmful fungi with a mixture of compounds I, II and/or IV and at least one fungicide from groups A) to F), as described above, is more efficient than combating those fungi with individual compounds I, II or IV or individual fungicides from groups A) to F). By applying compounds I, II and/or IV together with at least one active substance from groups A) to I) a synergistic effect can be obtained, i.e. more then simple addition of the individual effects is obtained (synergistic mixtures).
According to this invention, applying the compounds I, II and/or IV together with at least one further active substance is to be understood to denote that at least one compound of formula I, II and/or IV and at least one further active substance occur simultaneously at the site of action (i.e. the harmful fungi to be controlled or their habitats such as infected plants, plant propagation materials, particularly seeds, surfaces, materials or the soil as well as plants, plant propagation materials, particularly seeds, soil, surfaces, materials or rooms to be protected from fungal attack) in a fungicidally effective amount. This can be obtained by applying the compounds I, II and/or IV and at least one further active substance simultaneously, either jointly (e.g. as tank-mix) or sperately, or in succession, wherein the time interval between the individual applications is selected to ensure that the active substance applied first still occurs at the site of action in a sufficient amount at the time of application of the further active substance(s). The order of application is not essential for working of the present invention.
In binary mixtures, i.e. compositions according to the invention comprising one compound I, II or IV (component 1) and one further active substance (component 2), e.g. one active substance from groups A) to I), the weight ratio of component 1 and component 2 generally depends from the properties of the active substances used, usually it is in the range of from 1:100 to 100:1, regularly in the range of from 1:50 to 50:1, preferably in the range of from 1:20 to 20:1, more preferably in the range of from 1:10 to 10:1 and in particular in the range of from 1:3 to 3:1.
In ternary mixtures, i.e. compositions according to the invention comprising one compound I (component 1) and a first further active substance (component 2) and a second further active substance (component 3), e.g. two active substances from groups A) to I), the weight ratio of component 1 and component 2 depends from the properties of the active substances used, preferably it is in the range of from 1:50 to 50:1 and particularly in the range of from 1:10 to 10:1, and the weight ratio of component 1 and component 3 preferably is in the range of from 1:50 to 50:1 and particularly in the range of from 1:10 to 10:1.

The fungicidal action of the compounds of the formulae I and II was demonstrated by the following experiments:
The spray soultions were prepared in several steps:
The stock solution were prepared by adding a mixture of acetone and/or dimethylsulfoxide and the wetting agent/emulsifier Wettol, which is based on ethoxylated alkylphenoles, in a relation (volume) solvent-emulsifier of 99 to 1 to 25 mg of the compound to give a total of 10 ml. Water was then added to total volume of 100 ml. This stock solution was diluted with the described solvent-emulsifier-water mixture to the given concentration.
Leaves of pot-grown soy bean seedlings were inoculated with spores of Phakopsora pachyrhizi. To ensure the success of the artificial inoculation, the plants were transferred to a humid chamber with a relative humidity of about 95% and 20 to 24° C. for 24 h. The next day the plants were cultivated for 2 days in a greenhouse chamber at 23-27° C. and a relative humidity between 60 and 80%. Then the plants were sprayed to run-off with an aqueous suspension, containing the concentration of active ingredient or their mixture as described below. The plants were allowed to air-dry. Then the trial plants were cultivated for 14 days in a greenhouse chamber at 23-27° C. and a relative humidity between 60 and 80%. The extent of fungal attack on the leaves was visually assessed as % diseased leaf area. The plants which had been treated with an aqueous active compound preparation comprising 300 ppm of the active compounds of examples 1, 2, 3, 4, 5, 6, 11, 13, 16, 17, 18 and 20 showed an infection of 0%, whereas the untreated plants were 60% infected.

Leaves of pot-grown wheat seedling were sprayed to run-off with an aqueous suspension of the active compound or their mixture, prepared as described. The plants were allowed to air-dry. At the following day the plants were inoculated with an aqueous spore suspension of Septoria tritici. Then the trial plants were immediately transferred to a humid chamber at 18-22° C. and a relative humidity close to 100%. After 4 days the plants were transferred to a chamber with 18-22° C. and a relative humidity close to 70%. After 4 weeks the extent of fungal attack on the leaves was visually assessed as % diseased leaf area. The plants which had been treated with an aqueous active compound preparation comprising 300 ppm of the active compounds of examples 3, 4, 5, 6, 7, 9, 10, 12, 13, 16 and 18 showed an infection of at most 15%, whereas the untreated plants were 90% infected.
3. Preventative Control of Grey Mold (Botrytis cinerea) on Leaves of Green Pepper
Young seedlings of green pepper were grown in pots to the 2 to 3 leaf stage. These plants were sprayed to run-off with an aqueous suspension, containing the concentration of active ingredient or their mixture mentioned in the table below. The next day the treated plants were inoculated with a spore suspension of Botrytis cinerea in a 2% aqueous biomalt solution. Then the trial plants were immediately transferred to a dark, humid chamber. After 5 days at 22 to 24° C. and a relative humidity close to 100% the extent of fungal attack on the leaves was visually assessed as % diseased leaf area. The plants which had been treated with an aqueous active compound preparation comprising 300 ppm of the active compounds of examples 12, 17, 19 and 20 showed an infection of at most 10%, whereas the untreated plants were 100% infected.
