Stericidal composition

Abstract

A fungicidal composition containing a mixture of components (A) and (B) as defined in claim 1, and the use of the composition in agriculture or horticulture for controlling or preventing infection of plants by phytopathogenic microorganisms, preferably fungi.

Description

Technical Field

[0001] The present invention relates in particular to a novel bactericidal composition (or fungicidal composition) for treating phytopathogenic diseases affecting useful plants caused by phytopathogenic fungi, and to a method for controlling such diseases and / or fungi affecting useful plants.

Background Art

[0002] Although many bactericidal compounds belonging to various different chemical classifications have been developed / are under development for use as fungicides in crops of useful plants, the resistance and effectiveness of crops against specific phytopathogenic fungi do not necessarily meet the requirements related to agricultural practice in many respects. WO 2018 / 102345 discloses the use of aureobasidin A as an agricultural fungicide for treating, preventing or controlling fungal infections in plants and seeds. Aureobasidin A is an antifungal cyclic depsipeptide antibacterial agent produced by Aureobasidium pullulans. See, for example, Takesako et al., The Journal of Antibiotics, 1991, 44, 919-924.

[0003] However, there continues to be a need to find novel compositions having excellent biological properties for use in controlling or preventing ectoparasitism of plants by phytopathogenic fungi. For example, compositions having a broader activity spectrum, improved crop resistance, synergistic interactions or enhanced properties, or compositions that exhibit a more rapid onset of action, or have a longer-lasting residual activity, or that enable a reduction in the number of applications and / or the application rate of the compounds and compositions required for effective control of plant pathogens, thereby enabling the implementation of beneficial resistance management, reduced environmental impact, and reduced exposure to workers.

[0004] The use of a composition containing a mixture of different bactericidal compounds having different mechanisms of action can meet some of these requirements (for example, by combining fungicides having different spectra of activity).

SUMMARY OF THE INVENTION

MEANS FOR SOLVING THE PROBLEM

[0005] According to the present invention, there is provided a bactericidal composition comprising a mixture of components (A) and (B) as active ingredients, wherein component (A) is a cyclic depsipeptide of formula (I):

CHEMICAL

[0006] Generally, the weight ratio of component (A) to component (B) can be from 100:1 to 1:1000, preferably from 100:1 to 1:800, more preferably from 50:1 to 1:800, and even more preferably from 20:1 to 1:600.

[0007] In some preferred embodiments of the present invention, the weight ratio of component (A) to component (B) can be 1:1, or 1:1.2, or 2:1, or 4:1, or 8:1, or 16:1, or 1:200, or 1:100, or 1:50, or 1:25, or 1:20, or 1:12.5, or 1:10, or 1:6.2, or 1:5, or 1:2.5.

[0008] According to a second aspect of the present invention, there is provided a method for controlling or preventing phytopathogenic diseases, particularly those caused by phytopathogenic fungi, in useful plants or their propagation materials, the method comprising applying to the useful plant, its habitat or its propagation materials a composition as defined in the present invention. A method comprising applying the composition according to the present invention to a useful plant or its habitat, more preferably to a useful plant, is preferred. A method comprising applying the composition according to the present invention to the propagation material of a useful plant is even more preferred.

[0009] According to a third aspect of the present invention, there is provided the use of a composition comprising components (A) and (B) as defined in the present invention as a fungicide.

[0010] Surprisingly and substantially, it has been found that by using in combination the compound of formula (I), the compound of component (B), and optionally the compound of component (C), the effectiveness of the compound of formula (I) against fungi can be enhanced, and vice versa. Also, the use of the composition of the present invention can be effective against a wider range of such fungi than those that can be controlled by the individual active ingredients when used alone.

[0011] Advantages conferred by the specific fungicidal compositions according to the present invention can include, inter alia, an advantageous level of biological activity for protecting plants from diseases caused by fungi, or excellent properties for use as an agrochemical active ingredient (e.g., high biological activity, advantageous activity spectrum, increased safety profile, improved physicochemical properties, or increased biodegradability).

[0094] This list is not meant to represent any limitation, however, preferably, useful plants can be selected from the group consisting of wheat, barley, rice, soybean, apple, almond, cherry, raspberry, grape, cucumber, peanut, tomato, strawberry, citrus and banana.

[0095] The term "useful plant" should be understood to also include useful plants that have been rendered resistant to herbicides such as bromoxynil, or a class of herbicides (e.g., HPPD inhibitors, ALS inhibitors such as primisulfuron, prosulfuron and trifloxysulfuron, EPSPS (5-enol-pyruvyl-shikimate-3-phosphate synthase) inhibitors, GS (glutamine synthetase) inhibitors, etc.) by conventional breeding or genetic engineering methods. An example of a crop that has been rendered resistant to imidazolinones such as imazamox by conventional breeding (mutation induction) is Clearfield® summer canola. Examples of crops that have been rendered resistant to herbicides or a class of herbicides by genetic engineering methods include glyphosate- and glufosinate-resistant corn varieties commercially available under the trade names RoundupReady®, Herculex I® and LibertyLink®.

[0096] The term "useful plant" should be understood to also include useful plants transformed using recombinant DNA technology such that they are capable of synthesizing one or more selectively acting toxins, such as those known from toxin-producing bacteria. Examples of toxins that may be expressed include δ-endotoxin, vegetative insecticidal protein (Vip), insecticidal proteins of nematode symbiotic bacteria, and toxins produced by scorpions, arachnids, large wasps and fungi.

[0097] An example of a crop modified to express a Bacillus thuringiensis toxin is Bt corn KnockOut® (Syngenta Seeds). An example of a crop containing two or more genes encoding insecticidal resistance and thus expressing two or more toxins is VipCot® (Syngenta Seeds). Crops or their seed material can also be resistant to multiple pests (so-called stacked transgenic events when formed by genetic modification). For example, a plant can be herbicide resistant, such as Herculex I® (Dow AgroSciences, Pioneer Hi-Bred International), and at the same time have the ability to express an insecticidal protein.

[0098] Examples of toxins that can be expressed by such genetically modified plants include insecticidal proteins such as insecticidal proteins derived from Bacillus cereus or Bacillus popliae; or insecticidal proteins derived from Bacillus thuringiensis such as δ-endotoxins such as CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c, or vegetative insecticidal proteins (VIP) such as VIP1, VIP2, VIP3 or VIP3A; or insecticidal proteins of nematode symbiotic bacteria such as Photorhabdus luminescens, Xenorhabdus nematophilus, such as species of the genus Photorhabdus or species of the genus Xenorhabdus; toxins produced by animals such as scorpion toxin, spider toxin, wasp toxin and other insect-specific neurotoxins; toxins produced by fungi such as Streptomycete toxins, plant lectins such as pea lectin, barley lectin or pine mushroom lectin; agglutinin; protease inhibitors such as trypsin inhibitor, serine protease inhibitor, patatin, cystatin, papain inhibitor; ribosome-inactivating proteins (RIP) such as ricin, corn-RIP, abrin, luffin, saporin or bryodin; steroid metabolic enzymes such as 3-hydroxysteroid oxidase, ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidase, ecdysone inhibitor, HMG-COA-reductase, ion channel blockers such as sodium or calcium blockers, larval hormone esterase, diuretic hormone receptor, stilbene synthase, bibenzyl synthase, chitinase and glucanase.

[0099] In connection with the present invention, it should be understood that δ-endotoxins such as, for example, CryIA(b), CryIA(c), CryIF, CryIF(a2), CryIIA(b), CryIIIA, CryIIIB(b1) or Cry9c, or vegetative insecticidal proteins (VIPs) such as, for example, VIP1, VIP2, VIP3 or VIP3A, are also in particular hybrid toxins, truncated toxins and modified toxins. Hybrid toxins are recombinantly produced by new combinations of different domains of these proteins (see, for example, WO 02 / 15701). An example of a truncated toxin is the truncated CryIA(b) expressed in Bt11 maize manufactured by Syngenta Seed SAS, as described below. In the case of modified toxins, one or more amino acids of the native toxin are replaced. In such amino acid substitutions, preferably a protease recognition sequence that does not occur naturally is inserted into the toxin. For example, in the case of CryIIIA055, a cathepsin D-recognition sequence is inserted into the CryIIIA toxin (see WO 03 / 018810).

[0100] Examples of such toxins, or of genetically modified plants capable of synthesizing such toxins, are disclosed, for example, in EP-A-0 374 753, WO 93 / 07278, WO 95 / 34656, EP-A-0 427 529, EP-A-451 878 and WO 03 / 052073.

[0101] The process for preparing such genetically modified plants is generally known to those skilled in the art and is described, for example, in the above-mentioned publications. CryI-type deoxyribonucleic acids and their preparation are known, for example, from WO 95 / 34656, EP-A-0 367 474, EP-A-0 401 979 and WO 90 / 13651.

[0102] The toxins contained in genetically modified plants confer resistance to harmful insects on the plants. Such insects can be any of the insect taxa, but are particularly commonly found in beetles (Coleoptera), dipterous insects (Diptera) and butterflies (Lepidoptera).

[0103] Genetically modified plants containing one or more genes encoding insecticidal resistance and expressing one or more toxins are known, and some of them are commercially available. Examples of such plants are as follows: YieldGard® (maize variety expressing the CryIA(b) toxin); YieldGard Rootworm® (maize variety expressing the CryIIIB(b1) toxin); YieldGard Plus® (maize variety expressing the CryIA(b) and CryIIIB(b1) toxins); Starlink® (maize variety expressing the Cry9(c) toxin); Herculex I® (maize variety expressing the CryIF(a2) toxin and the enzyme phosphinothricin N-acetyltransferase (PAT) to achieve resistance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety expressing the CryIA(c) toxin); Bollgard I® (cotton variety expressing the CryIA(c) toxin); Bollgard II® (cotton variety expressing the CryIA(c) and CryIIA(b) toxins); VIPCOT® (cotton variety expressing the VIP toxin); NewLeaf® (potato variety expressing the CryIIIA toxin); NatureGard® and Protecta®.

[0133] The composition of the present invention can also be used in crop enhancement. In the present invention, "crop enhancement" means improvement of plant vigor, improvement of plant quality, improved tolerance to stress factors, and / or improved input use efficiency.

[0134] In the present invention, "improvement of plant vigor" means that a particular trait is qualitatively or quantitatively improved when compared to the same trait in a control plant grown under the same conditions in the absence of the method of the present invention. Such traits include, but are not limited to, early and / or improved germination, improved germination, ability to use fewer seeds, increased root growth, more developed root systems, increased nodulation, increased shoot growth, increased tillering, stronger tillering, more productive tillering, increased or improved plant stand, fewer plant lodgings, increase and / or improvement in plant height, increase in plant weight (fresh or dry), larger leaf blades, greener leaf color, increased pigment content, increased photosynthetic activity, earlier flowering, longer spikes, early grains, increased number of seeds, fruits, or sheaths, increased number of sheaths or spikes, increased number of seeds per sheath or spike, increased seed mass, enhanced seed ripening, fewer basal leaves, delayed senescence, improvement of plant vigor, increase in amino acid levels in storage tissues, and / or fewer required inputs (e.g., less required fertilizer, water, and / or labor). A plant with improved vigor may have any of the aforementioned traits, or any combination or increase of two or more of the aforementioned traits.

[0135] In the present invention, "improvement of plant quality" means that a particular trait is qualitatively or quantitatively improved when compared to the same trait in a control plant grown under the same conditions in the absence of the method of the present invention. Such traits include, but are not limited to, improved appearance of the plant, reduced ethylene (reduced production and / or suppression of sensitivity), for example, improvement of the quality of harvested products such as seeds, fruits, leaves, vegetables, etc. (such improvement in quality may appear as an improvement in the visual appearance of the harvested product), improved carbohydrate content (e.g., increase in the amount of sugar and / or starch, improved sugar-acid ratio, reduction of reducing sugars, increase in the sugar production rate), improved protein content, improved oil content and composition, improved nutritional value, reduction of anti-nutritional compounds, improved functional properties (e.g., improved taste), and / or improvement of the health benefits for consumers (e.g., increased levels of vitamins and antioxidants), which may be expressed as improved post-harvest characteristics (e.g., enhanced shelf life and / or storage stability, easier processability, easier compound extraction), more uniform crop development (e.g., synchronized germination, flowering, and / or fruiting of plants), and / or improved seed quality (e.g., for use in the next cultivation period). A plant with improved quality may have any of the aforementioned traits, or any combination or increase of two or more of the aforementioned traits.

[0136] In the present invention, "improved tolerance to stress factors" means that a particular trait is qualitatively or quantitatively improved when compared to the same trait in a control plant grown under the same conditions in the absence of the method of the present invention. Such traits include, but are not limited to, increased tolerance and / or resistance to abiotic stress factors that cause suboptimal growth conditions such as drought (e.g., any stress that results in a lack of water in the plant, insufficient water uptake capacity, or a decrease in the supply of water to the plant), cold exposure, heat exposure, osmotic stress, UV stress, flooding, increased salinity (e.g., in the soil), exposure to increased minerals, ozone exposure, high light exposure, and / or limited availability of nutrients (e.g., nitrogen and / or phosphorus nutrients). A plant having improved tolerance to stress factors may have any of the aforementioned traits, or any combination or two or more increases of the aforementioned traits. In the case of drought and nutrient stress, such improved tolerance may be due to, for example, more efficient uptake, use, or retention of water and nutrients.

[0137] In the present invention, "improved input use efficiency" means that a plant can grow more efficiently using a given input level as compared to the growth of a control plant grown under the same conditions in the absence of the method of the present invention. Specifically, inputs include, but are not limited to, fertilizers (nitrogen, phosphorus, potassium, micronutrients, etc.), light, and water. A plant having improved input use efficiency may have improved use of any of the aforementioned inputs, or any combination of two or more of the aforementioned inputs.

[0138] Other enhancements of the crops of the present invention include a reduction in plant height, or a reduction in tillering, which are beneficial features in crops or conditions where it is desirable to have less biomass and fewer tillers.

[0139] Any or all of the above crop enhancements can lead to an improvement in yield, for example, by improving the physiological functions of plants, plant growth and development, and / or plant structure. In the context of the present invention, "yield" includes, but is not limited to, (i) an increase in biomass production, grain yield, starch content, oil content, and / or protein content that can be attributed to (a) an increase in the amount produced by the plant itself, or (b) an improved ability to harvest the plant body; (ii) an improvement in the harvested composition (e.g., an improved sugar-acid ratio, an improved oil composition, an increased nutritional value, a reduction in anti-nutritional compounds, an increased consumer health benefit); and / or (iii) an increased / facilitated ability to harvest the crop, improved processability of the crop, and / or better storage stability / shelf life. An increased yield of an agricultural plant means that, when quantitative measurements can be made, the yield of the product of each plant increases by a measurable amount compared to the yield of the same product of plants produced under the same conditions but without applying the present invention. According to the present invention, it is preferred that the yield increases by at least 0.5%, more preferably at least 1%, still more preferably at least 2%, and even more preferably at least 4%, preferably 5% or more.

[0140] Any or all of the above crop enhancements may also result in an improved use of land. That is, land that has not been available for cultivation or has not been optimally utilized may become available. For example, plants that exhibit an increased ability to survive in drought conditions may be cultivable in areas with sub-optimal rainfall, such as perhaps the periphery of a desert or even the desert itself.

[0141] In certain embodiments of the present invention, crop enhancement is carried out in the substantial absence of pressure from pests and / or diseases and / or abiotic stress. According to a further aspect of the present invention, the improvement of plant vigor, stress tolerance, quality and / or yield is carried out in the substantial absence of pressure from pests and / or diseases. For example, pests and / or diseases can be controlled by insecticidal treatments applied before or simultaneously with the methods of the present invention. In yet another aspect of the present invention, the improvement of plant vigor, stress tolerance, quality and / or yield is carried out in the absence of pressure from pests and / or diseases. In further embodiments, the improvement of plant vigor, quality and / or yield is carried out in the absence or substantial absence of abiotic stress.

[0142] The compositions of the present invention may be used in the field of protecting stored products from fungal attack. In the present invention, the term "stored product" is understood to mean natural substances of plant and / or animal origin and their processed forms for which long-term protection from their natural life cycle is desired. Stored products of plant origin, such as plants or parts thereof (e.g., stems, leaves, tubers, seeds, fruits, or grains), can be protected in their freshly harvested state or in a processed form such as pre-dried, humidified, ground, milled, pressed, or roasted. The definition of stored products also includes wood in the form of unprocessed wood (such as construction wood, power transmission towers, and fences) and wood in the form of finished products (such as furniture or wooden articles). Stored products of animal origin are leather, leather products, furs, and hairs, etc. The compositions of the present invention can prevent adverse effects such as spoilage, discoloration, or mold growth. Preferably, "stored product" is understood to mean natural substances of plant origin and / or their processed forms, and more preferably, fruits and their processed forms (such as pomaceous fruits, stone fruits, berries, and citrus fruits, and their processed forms, etc.). In another preferred embodiment of the present invention, "stored product" is understood to mean wood.

[0143] Therefore, a further aspect of the present invention is a method for protecting stored products, which comprises applying the compositions of the present invention to the stored products.

[0144] The composition of the present invention can also be used in the field of protecting industrial substrates from fungal attack. In the present invention, the term "industrial substrate" includes paper; carpets; buildings; cooling and heating systems; wall panels; ventilation and air conditioning systems, etc.; preferably, the "industrial substrate" is understood to mean wall panels. The composition of the present invention can prevent adverse effects such as spoilage, discoloration, or mold growth.

[0145] Some compositions according to the present invention have a penetration and translocation effect and can be used as foliar, soil, and seed treatment fungicides.

[0146] In the composition according to the present invention, it is possible to inhibit or control phytopathogenic microorganisms occurring in plants or parts of plants (fruits, flowers, leaves, stems, tubers, roots) in different useful plants, and moreover, at the same time, the parts of the plants that grow subsequently are also protected from attack by phytopathogenic microorganisms.

[0147] The composition according to the present invention is applicable to phytopathogenic microorganisms, useful plants threatened by microbial attack, their habitats, their propagation materials, storage articles, or technical materials.

[0148] The composition according to the present invention can be applied before or after the infection of useful plants, their propagation materials, storage articles, or technical materials by microorganisms.

[0149] The composition of the present invention can also be used in the field of protecting industrial materials from fungal attack. According to the present invention, the term "industrial material" refers to non-living materials prepared for use in industry. For example, industrial materials intended to be protected from fungal attack can be adhesives, glues, paper, cardboard, fabrics, carpets, leather, wood, structures, paints, plastic articles, cooling lubricants, aqueous working fluids and other materials that may be subject to ectoparasitism or degradation by microorganisms. Cooling and heating systems, ventilation and air conditioning systems and components of production plants, such as cooling water circulation paths that may be impaired by the growth of microorganisms, can also be described as one of the materials to be protected. The composition according to the present invention can prevent adverse effects such as corrosion, discoloration or mold.

[0150] The amount of the combination according to the present invention to be applied will depend on various factors such as the compound employed; the object to be treated, such as plants, soil or seeds; the type of treatment, such as spraying, dusting or seed coating; the purpose of the treatment, such as prevention or treatment; the type of fungus to be controlled; or the application time.

[0151] A composition comprising component (A) in combination with component (B) can be applied, for example, in a single "formulated" form, in a complex spray mixture such as a "tank mixture" composed of individual formulations of a single active ingredient, and, sequentially, i.e., when applied successively within a moderately short period of time, such as several hours or several days, the single active ingredients can be applied in combination. The order of application of the compound of component (A) and the active ingredient of component (B) is not important for the action of the present invention.

[0152] The composition according to the present invention is an active ingredient that is useful prophylactically and / or therapeutically in the field of pest control even at low application rates.

[0153] When applied to useful plants, component (A) is applied in an amount of 25 g a.i. / ha to 500 g a.i. / ha, accompanied by 100 g a.i. / ha to 7500 g a.i. / ha of component (B).

[0154] In a preferred embodiment of the present invention, a method for controlling or preventing phytopathogenic diseases, especially those caused by phytopathogenic fungi, in useful plants or their propagation materials comprises applying to the useful plant, its habitat or its propagation materials, the composition as defined in the present invention, where component (A) is applied in an amount of 25 g a.i. / ha to 500 g a.i. / ha, accompanied by 100 g a.i. / ha to 7500 g a.i. / ha of component (B).

[0155] The method for controlling or preventing phytopathogenic diseases according to the present invention can be particularly effective against phytopathogenic fungi selected from the group consisting of Alternaria, Botrytis, Cercospora, Colletotrichum, Corynespora, Guignardia, Mycosphaerella, Monilinia, Penicillium, Phakopsora, Phomopsis, Podosphaera, Pseudopezicula, Septoria, Uncinula and Venturia.

[0156] The method for controlling or preventing phytopathogenic diseases according to the present invention may be particularly effective against phytopathogenic fungi selected from the group consisting of Alternaria solani, Alternaria alternata, Alternaria porri, Botrytis cinerea, Botrytis allii, Botrytis squamosa, Cercospora capsici, Colletotrichum lagenarium, Corynespora cassiicola, Guignardia bidwellii, Monilinia fructicola, Monilinia fructigena, Monilinia laxa, Penicillium digitatum, Penicillium italicum, Penicillium expansum, Phomopsis viticola, Podosphaera leucotricha, Podosphaera xanthii, Pseudopezicula tracheiphila, Septoria tritici, Uncinula necator, and Venturia inaequalis.

[0157] A method for controlling or preventing phytopathogenic diseases, particularly those caused by phytopathogenic fungi, which comprises applying the composition according to the invention to useful plants selected from the group consisting of cereals, fruits and nuts, vegetables, field crops, oilseed crops, forage crops, forest plants, horticultural crops, flower gardening, greenhouse and nursery plants, propagation materials, culinary herbs and spices, and medicinal herbs, is preferred.

[0158] A more preferred method for controlling or preventing phytopathogenic diseases, particularly those caused by phytopathogenic fungi, which comprises applying the composition according to the invention to useful plants selected from the group consisting of wheat, barley, rice, soybeans, apples, almonds, cherries, raspberries, grapes, cucumbers, peanuts, tomatoes, strawberries, citrus fruits and bananas.

[0159] In one embodiment of the invention, the method for controlling or preventing phytopathogenic diseases according to the invention may be particularly effective against phytopathogenic fungi selected from the group consisting of Alternaria, Cercospora, Colletotrichum, Corynespora, Mycosphaerella, Phakopsora, Phomopsis and Septoria in soybean plants.

[0160] In one embodiment of the invention, the method for controlling or preventing phytopathogenic diseases according to the invention may be particularly effective against phytopathogenic fungi selected from the group consisting of Alternaria spp., Cercospora kikuchii, Cercospora sojina, Phakopsora pachyrhizi and Septoria glycines in soybean plants.

[0161] The present invention also provides a bactericidal composition comprising, together with an agriculturally acceptable carrier and optionally a surfactant, a synergistically effective amount of a combination of the above components (A) and (B). In said composition, the weight ratio of (A) to (B) is, as already described herein, preferably from 100:1 to 1:800, more preferably from 100:1 to 1:800, even more preferably from 50:1 to 1:600, and even more preferably from 20:1 to 1:20.

[0162] The compositions of the present invention can be employed in any conventional form, for example, two-component systems, dry seed treatment powders (DS), seed treatment emulsions (ES), seed treatment flowable concentrates (FS), seed treatment solutions (LS), seed treatment water dispersible powders (WS), seed treatment capsule suspensions (CF), seed treatment gels (GF), emulsion concentrates (EC), suspension concentrates (SC), suspoemulsions (SE), capsule suspensions (CS), water dispersible granules (WG), emulsifiable granules (EG), emulsions, oil-in-water (EO), emulsions, water-in-oil (EW), microemulsions (ME), oil dispersions (OD), oil miscible flowables (OF), oil miscible liquids (OL), soluble concentrates (SL), ultra-low volume suspensions (SU), ultra-low volume liquids (UL), industrial concentrates (TK), dispersible concentrates (DC), wettable powders (WP), or any technically preferred formulation in combination with an agriculturally acceptable adjuvant.

[0163] Such compositions can be produced in a conventional manner, for example, by mixing the active ingredient with a suitable inert formulation (diluent, solvent, filler, and optionally other formulation components). Also, conventional slow-release formulations can be employed when a long-lasting efficacy is intended. In particular, formulations applied in spray forms such as water-dispersible concentrates (e.g., EC, SC, DC, OD, SE, EW, EO, etc.), wettable powders, and granules can contain compounds that provide an adjuvant effect. In some embodiments, the compositions of the present invention can be produced by mixing a fermentation broth containing aureobasidin A and one or more other cyclic depsipeptides of formula (I-A) or their stereoisomers with component (B). In some other embodiments, the compositions of the present invention can be produced by mixing a fermentation broth containing Persephacin A and one or more other cyclic depsipeptides of formula (I-B) or their stereoisomers with component (B).

[0164] The seed coating formulation utilizes the combination and diluent of the present invention in a suitable seed coating formulation form, such as an aqueous suspension or a dry powder form having good adhesiveness to seeds, and is applied to seeds in a manner known per se. Such seed coating formulations are known in the art. The seed coating formulation may contain a single active ingredient or, for example, a combination of active ingredients in encapsulated form as slow-release capsules or microcapsules.

[0165] Generally, the formulation contains 0.01 - 90% by weight of the active agent, 0 - 20% of an agriculturally acceptable surfactant, and 10 - 99.99% of a solid or liquid inert formulation and formulation aids. The active agent is composed of at least the compound of formula (I), together with component (B), and optionally component (C), and other active agents, particularly fungicides or preservatives, etc. The concentrated form of the composition generally contains about 2 - 80%, preferably about 5 - 70% by weight of the active agent. The application form of the formulation can contain, for example, 0.01 - 20% by weight, preferably 0.01 - 5% by weight of the active agent. Commercially available products are preferably formulated as concentrates, but end-users will usually utilize diluted formulations.

[0166] Surprisingly, it has been found that a certain weight ratio of component (A) to component (B) can bring about synergistic activity. Accordingly, a further aspect of the present invention is a composition in which component (A) and component (B) are present in the composition in an amount that brings about a synergistic effect. This synergistic activity is evident from the fact that the bactericidal activity of the composition containing component (A) and component (B) is greater than the sum of the bactericidal activities of component (A) and component (B). This synergistic activity extends the scope of action of component (A) and component (B) in two ways. First, the application rates of component (A) and component (B) are reduced while the action remains equally good, which means that even in the low application rate range where the two individual components become completely ineffective, the active ingredient mixture can still achieve a high level of control of plant pathogens. Second, the range of plant pathogens that can be controlled is substantially expanded.

[0167] A synergistic effect always exists when the action of the combination of active ingredients is greater than the sum of the actions of the individual components. The expected activity E for a given combination of active ingredients can be calculated as follows according to the so-called COLBY's formula (COLBY, S.R. “Calculating synergistic and antagonistic responses of herbicide combination”. Weeds, Vol. 15, pages 20 - 22; 1967): ppm = milligrams of active ingredient (= a.i) per liter of spray mixture X = % of action by active ingredient (A) using p ppm of active ingredient Y = % of action by active ingredient (B) using q ppm of active ingredient.

[0168] According to COLBY, the expected (active) action of active ingredient (A)+(B) using p + q ppm of active ingredient is:

Equation

[0169] When the actually observed effect (O) is greater than the expected effect (E), the effect of the combination is superadditive, i.e., there is a synergistic effect. In mathematical terms, the synergistic effect corresponds to the positive value of the difference (O - E). In the case of pure complementary addition of activities (expected activity), the difference (O - E) is zero. A negative value of the difference (O - E) indicates that the activity is lost compared to the expected activity.

[0170] However, apart from the actual synergistic effect regarding the bactericidal activity, the compositions of the present invention may further have other surprisingly advantageous properties. Examples of such advantageous properties that can be mentioned are: more advantageous degradability; improved toxicological and / or biotoxicological behavior; or improved properties of useful plants (germination, crop yield, more developed root systems, increased tillering, increased plant height, larger leaf blades, fewer basal leaves, stronger tillering, greener leaf color, less fertilizer required, fewer seeds required, more productive tillering, earlier flowering, earlier grains, less plant lodging, increased shoot growth, improved plant vigor, and earlier germination, etc.).

[0171] The following examples are for illustrative purposes of the present invention and are not meant to limit the present invention in any way.

Examples

[0172] Biological Examples The compositions according to the present invention are tested for their biological (bactericidal) activity using application rates in which component (A) is applied in an amount of 25 g a.i. / ha to 500 g a.i. / ha, accompanied by component (B) of 100 g a.i. / ha to 7500 g a.i. / ha.

[0173] The compositions according to the present invention are tested for their biological (bactericidal) activity as a dimethyl sulfoxide (DMSO) solution using one or more of the following protocols (Examples 1 - 1 and 1 - 2). A standard description of the liquid culture test is given in Example 1.

[0174] Oreobasidin A and its synthesis are known from Takesako et al., The Journal of Antibiotics, 1991, 44, 919 - 924. Oreobasidin A is separated from the fermentation broth by extraction with ethyl acetate, followed by extraction of the ethyl acetate concentrate with a mixture of MeOH:H2O (80% by volume) and cyclohexane (20% by volume), and purification by silica gel column chromatography (elution with hexane:ethyl acetate), followed by reverse phase column chromatography (RP18, elution with acetonitrile:H2O). As described above, component (B) of the composition is known and can be prepared using methods known in the art and / or methods reported in the literature, and / or is commercially available.

[0175] Example 1: Liquid Medium Test in Well Plates A freshly prepared or cryopreserved fungal mycelial fraction or conidia suspension from a fungal liquid medium is directly mixed with a nutrient liquid medium. A DMSO solution of the test compound (up to 10 mg / mL) is diluted 50-fold with 0.025% Tween 20, and 10 μl of this solution is pipetted into a microtiter plate (96-well type). Then, a nutrient liquid medium containing the fungal spore / mycelial fraction is added to obtain the final concentration of the compound to be tested. The test plate is incubated in the dark at 24 °C and 96% relative humidity (rh). The inhibition of fungal growth is measured photometrically and visually 3 - 7 days later depending on the pathogen response system, and the antifungal activity ratio against the untreated test subject is calculated.

[0176] Example 1 - 1: Botrytis cinerea (Gray Mold) Cryopreserved fungal conidia were directly mixed with a nutrient liquid medium (PDB potato dextrose liquid medium). After placing the DMSO solution of the test composition in a microtiter plate (96-well type), a nutrient liquid medium containing the fungal conidia was added. The test plate was incubated at 24 °C, and the inhibition of growth was determined photometrically after 72 hours.

[0177] Example 1-2: Alternaria solani (Early blight of tomato / potato) Conidia of the fungus stored at low temperature were directly mixed into a nutrient liquid medium (PDB potato dextrose liquid medium). After placing the DMSO solution of the test composition into a microtiter plate (96-well type), the nutrient liquid medium containing the conidia of the fungus was added. The test plate was incubated at 24 °C, and the inhibition of growth was determined photometrically after 48 hours.

[0178] Results The results of the above tests are shown in Tables 1 and 2. These data show that in the combination of Aureobasidin A and other active ingredients of component (B), a synergistic bactericidal activity is observed against Botrytis cinerea and Alternaria solani at a certain weight ratio. According to COLBY, mathematically, the synergistic action factor SF corresponds to O / E.
