Description

 Fungicidal drug combinations

The present invention relates to novel drug combinations containing the known fungicidal active ingredient bixafen and at least one plant growth regulator, which are very well suited for controlling unwanted phytopathogenic fungi. The invention also relates to a process for the curative or preventive treatment of phytopathogenic fungi on plants or crops, in particular the treatment of seed, e.g. Cereal seed, and not least the treated seed itself.

It is already known that bixafen has fungicidal properties (see WO 03/070705). The effectiveness of this substance is good, but leaves in some cases to be desired.

Plant growth regulators, hereinafter also abbreviated to PGRs, are generally understood to mean compounds or mixtures which influence the behavior of ornamental or crop plants or their agricultural products through physiological (eg hormonal) effects in terms of growth and differentiation , PGRs can e.g. accelerate or retard the growth of plants, prolong or shorten the resting state, or promote root growth. In particular, some PGRs are capable of reducing plant height, stimulating germination, inducing flowering, darkening leaf color, or affecting the timing or efficiency of fruiting.

Thus plant growth regulators may e.g. inhibit the vegetative growth of plants, which is of interest on lawns, in ornamental plants, in orchards, on street embankments, on sports and industrial facilities, but also in the targeted inhibition of secondary drives such as tobacco. In agriculture, the inhibition of vegetative growth in cereals leads to reduced storage by means of a stalk reinforcement. Similar effect is achieved e.g. in rapeseed, sunflower and corn. Furthermore, by inhibiting vegetative growth, the number of plants / shoots per area can be increased.

Through plant growth regulators the yield can be influenced quantitatively (eg latex flow) or qualitatively (eg sugar content), the apikaidominance can be broken and side shoots can be promoted (eg ornamental plants), flowering and fruiting can be promoted (eg thinning of fruit trees for alternation breaking, Fruit abscission in olives for mechanical harvesting), the fruit ripeness can be harmonized with growth regulators, accelerated or retarded (eg capsule opening in cotton, ripening of tomatoes or bananas).

With growth regulators, plants can be made more resistant to environmental stress such as drought, cold or soil salt content. Finally, with plant growth regulators the Defoliation of crops are selectively induced in time, so that the mechanical harvest in crops such as cotton, potatoes or vines is facilitated or made possible.

Usually, growth regulators have no useful, direct fungicidal action, even though there are individual classes of growth regulators with minor fungicidal activity.

It is further known that mixtures of certain fungicidal carboxanilides with certain growth regulators have synergistic properties (see WO 2008/095890).

Since the ecological and economic requirements of modern fungicides are constantly increasing, for example with regard to spectrum of action, toxicity, selectivity, application rate, residue formation and favorable manufacturability, and in addition, e.g. Problems with resistance can occur, there is the constant task of developing new fungicides and fungicidal drug combinations that help overcome the disadvantages mentioned at least in some areas.

The present invention provides drug combinations or agents which solve the stated problem in at least some aspects.

It has now surprisingly been found that the active compound combinations or compositions according to the invention have a synergistic effect. As a result, on the one hand the usual application rate of the individual substances can be reduced. On the other hand, the active compound combinations according to the invention still offer a high degree of action against phytopathogens, even if the individual compounds are used in amounts in which they show no (sufficient) effect themselves. This basically allows a widening of the spectrum of action on the one hand and a higher safety in handling and lower environmental pollution on the other hand. In addition, it is possible, by using the combinations according to the invention, to achieve a greatly improved fungicidal activity while at the same time protecting against bearing damage by the hemi-reinforcing action of the growth regulators with only one plant treatment.

In addition to the fungicidal synergistic effect, the active compound combinations according to the invention can have further surprising properties which can also be called synergistic in a broader sense, such as: the expansion of the activity spectrum, for example to resistant pathogens of plant diseases; lower application rates of the active ingredient; sufficient pest control with the aid of the active compound combinations according to the invention even at such application rates at which the individual active ingredients show no or almost no effect; favorable behavior during formulation or during use, eg during milling, sieving, emulsification, dissolution or application; improved storage or light stability; more advantageous formation of residues; improved toxicological or ecotoxicological behavior; improved properties for the plant, eg better growth, increased crop yields, better developed root system, larger leaf area, greener leaves, stronger seedlings, less phytotoxicity, mobilization of the plant's defense, good plant tolerance. Thus, when applied, the active compound combinations or compositions according to the invention contribute significantly to the health of young cereal stocks, thereby increasing the wintering performance of the treated cereal seed and ensuring the formation of quality and yield. The active compound combinations according to the invention can also contribute to an improved systemic effect. Even if the individual active ingredients of the combination do not possess adequate systemic properties, the active ingredient combinations according to the invention can certainly exhibit this property. Similarly, the active compound combinations according to the invention can lead to an increased persistence of the fungicidal action.

It has now been found that containing drug combinations

The invention further comprises a method of treating seed.

The invention further relates to seed which has been treated according to one of the methods described in the previous paragraph. The seed according to the invention is used in processes for the protection of seed from undesired microorganisms. In these, a seed treated with at least one active ingredient according to the invention is used.

The active compound combinations or compositions according to the invention are also suitable for the treatment of seed. Much of the crop damage caused by harmful organisms is caused by infestation of the seed during storage or after sowing, and during and after germination of the plant. This phase is particularly critical because the roots and shoots of the growing plant are particularly sensitive and may cause even minor damage to the plant's death. There is therefore a great interest in protecting the seed and the germinating plant by using suitable means.

The control of phytopathogenic fungi by the treatment of the seed of plants has long been known and is the subject of constant improvement. Nevertheless, there are a number of problems in the treatment of seeds that can not always be satisfactorily resolved. Thus, it is desirable to develop methods for protecting the seed and the germinating plant, which eliminate or at least significantly reduce the additional application of crop protection agents after sowing or after emergence of the plants. It is also desirable to optimize the amount of the active ingredient used in such a way that the seed and the germinating plant are best protected against attack by phytopathogenic fungi, However, without damaging the plant itself by the active ingredient used. In particular, methods for treating seed should also include the intrinsic fungicidal properties of transgenic plants in order to achieve optimum protection of the seed and the germinating plant with a minimum of pesticide use.

The present invention therefore also relates to a method of protecting seed and germinating plants from the infestation of phytopathogenic fungi by treating the seed with an agent according to the invention. The invention also relates to the use of the seed treatment agents of the invention for protecting the seed and the germinating plant from phytopathogenic fungi. Furthermore, the invention relates to seed which has been treated with an agent according to the invention for protection against phytopathogenic fungi.

The control of phytopathogenic fungi, which damage plants after emergence, takes place primarily through the treatment of the soil and the above-ground parts of plants with pesticides. Due to concerns about the potential impact of crop protection products on the environment and human and animal health, efforts are being made to reduce the amount of active ingredients applied.

One of the advantages of the present invention is that due to the systemic properties of the active compound combinations or compositions according to the invention, the treatment of the seeds with these active ingredients or agents protects not only the seed itself, but also the resulting plants after emergence from phytopathogenic fungi. In this way, the immediate treatment of the culture at the time of sowing or shortly afterwards can be omitted.

Likewise, it is considered to be advantageous that the active compound combinations or compositions according to the invention can also be used in particular in the case of transgenic seed, wherein the plant growing from this seed is capable of expressing a protein which acts against pests. By treating such seeds with the active compounds or agents according to the invention, it is possible to combat pests already determined by the expression of, for example, insecticidal protein. Surprisingly, a further synergistic effect can be observed, which additionally increases the effectiveness for protection against pest infestation.

The compositions according to the invention are suitable for the protection of seed of any plant variety used in agriculture, in the greenhouse, in forests or in horticulture and viticulture. In particular, these are seeds of cereals (such as wheat, barley, rye, triticale, millet and oats), corn, cotton, soy, rice, potatoes, sunflower, bean, coffee, turnip (eg sugar beet and fodder beet), Peanut, canola, poppy, olive, coconut, cocoa, sugarcane, tobacco, vegetables (such as tomato, cucumber, onions and lettuce), turf and ornamental plants (see also below). special the importance of treating the seeds of cereals (such as wheat, barley, rye, triticale and oats), maize and rice is of major importance.

As also described below, the treatment of transgenic seed with the active compounds or agents according to the invention is of particular importance. This concerns the seed of plants containing at least one heterologous gene, e.g. allows the expression of a polypeptide or protein having insecticidal properties. The heterologous gene in transgenic seed may e.g. from microorganisms of the species Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavabacter, Glomus or Gliocladium. Preferably, this heterologous gene is derived from Bacillus sp., Wherein the gene product has an activity against the European corn borer and / or Western Com Rootworm. Most preferably, the heterologous gene is from Bacillus thuringiensis.

In the context of the present invention, the agent according to the invention is applied to the seed alone or in a suitable formulation. Preferably, the seed is treated in a state where it is so stable that no damage occurs during the treatment. In general, the treatment of the seed can be done at any time between harvesting and sowing. Usually, seed is used which has been separated from the plant and freed from flasks, shells, stalks, hull, wool or pulp. For example, seed may be used which has been harvested, cleaned and dried to a moisture content of below 15% by weight. Alternatively, seed may also be used which, after drying, e.g. treated with water and then dried again.

In general, care must be taken during the treatment of the seed that the amount of the agent of the invention applied to the seed and / or other additives is chosen so that the germination of the seed is not impaired or the resulting plant is not damaged. This is especially important for active ingredients, which can show phytotoxic effects in certain application rates.

The agents according to the invention can be applied directly, ie without containing further components and without being diluted. In general, it is preferable to apply the agents 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 e.g. in the following documents: US 4,272,417 A, US 4,245,432 A, US 4,808,430 A, US 5,876,739 A, US 2003/0176428 A1, WO 2002/080675 A1, WO 2002/028186 A2.

Particularly suitable nonionic dispersants are, in particular, ethylene oxide-propylene oxide, block polymers, alkylphenol polyglycol ethers and also trisylphenyl nol polyglycol ethers and their phosphated or sulfated derivatives. Suitable anionic dispersants are in particular lignosulfonates, polyacrylic acid salts and arylsulfonate-formaldehyde condensates.

The gibberellins are known (see R. Wegler "Chemie der Pflanzenschutz- und Schädlingsbekungsmittel", Vol. 2, Springer Verlag, 1970, pp. 401-412).

The seed dressing formulations which can be used according to the invention can be used either directly or after prior dilution with water for the treatment of seed of various kinds, including seed of transgenic plants. In this case, additional synergistic effects may occur in interaction with the substances formed by expression.

For the treatment of seed with the seed dressing formulations which can be used according to the invention or the preparations prepared therefrom by the addition of water, all mixing devices customarily usable for the dressing can be considered. Specifically, in the pickling procedure, the seed is placed in a mixer which adds either desired amount of seed dressing formulations either as such or after prior dilution with water and mixes until evenly distributed the formulation on the seed. Optionally, a drying process follows.

In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The term "parts" or "parts of plants" or "parts of plants" has been explained above.Propeas of the respective commercially available or in use plant varieties are particularly preferably treated according to the invention plants are understood as meaning new plants ("traits"). which have been bred either by conventional breeding, by mutagenesis or by recombinant DNA techniques. These may be varieties, breeds, biotypes and genotypes.

The treatment method according to the invention can be used for the treatment of genetically modified organisms (GMOs), eg. As plants or seeds are used. Genetically modified plants (or transgenic plants) are plants in which a heterologous gene has been stably integrated into the genome. The term "heterologous gene" essentially means a gene which is provided or assembled outside the plant and which, when introduced into the nuclear genome, the chloroplast genome or the hypochondriacal genome, imparts new or improved agronomic or other properties to the transformed plant Expressing protein or polypeptide or that it downregulates or shuts down another gene present in the plant or other genes present in the plant (for example by means of antisense technology, cosuppression technology or RNAi technology [RNA Interference]) A heterologous gene present in the genome is also referred to as a transgene A transgene defined by its specific presence in the plant genome is referred to as a transformation or transgenic event.

Depending on the plant species or plant varieties, their location and their growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention leads For example, the following effects are possible, which go beyond the actually expected effects: reduced application rates and / or extended spectrum of action and / or increased effectiveness of the active ingredients and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to dryness or water or soil salinity, increased flowering, crop relief, maturing, higher yields, larger fruits, greater plant height, intense green color of the leaf, earlier flowering, higher quality and / or higher nutritional value of the harvested products, higher sugar concentration in the fruits, better shelf life and / or processability of the harvested products.

At certain application rates, the active compound combinations according to the invention can also exert a strengthening effect on plants. They are also suitable for mobilizing the plant defense system against attack by undesirable phytopathogenic fungi and / or microorganisms and / or viruses. These may optionally be reasons for the increased effectiveness of the combinations according to the invention, for example against fungi. Plant-strengthening (resistance-inducing) substances in the present context should also mean those substances or substance combinations capable of stimulating the plant defense system in such a way that the treated plants, when subsequently inoculated with undesirable phytopathogenic fungi, have a considerable degree of resistance to these undesired ones exhibit phytopathogenic fungi. The substances according to the invention can therefore be employed for the protection of plants against attack by the mentioned pathogens within a certain period of time after the treatment. The period of time over which a protective effect is achieved generally extends from 1 to 70 days, preferably 1 to 30 days, after the treatment of the plants with the active substances.

Plants and plant varieties which are preferably treated according to the invention include all plants which have genetic material which gives these plants particularly advantageous, useful features (regardless of whether this was achieved by breeding and / or biotechnology).

Plants and plant varieties which are also preferably treated according to the invention are resistant to one or more biotic stressors, i. H. These plants have an improved defense against African and microbial pests such as nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and / or viroids.

Plants and plant varieties which can also be treated according to the invention are those plants which are resistant to one or more abiotic stress factors. Abiotic stress conditions may include, for example, drought, cold and heat conditions, osmotic stress, waterlogging, increased soil salt content, increased exposure to minerals, ozone conditions, - -

High light conditions, limited availability of nitrogen nutrients, limited availability of phosphorous nutrients or avoidance of shadows.

Plants and plant varieties which can also be treated according to the invention are those plants which are characterized by increased yield properties. An increased yield can in these plants z. B. based on improved plant physiology, improved plant growth and improved plant development, such as Wasserverwertungseffϊzienz, Wasserhalteeffϊcienz, improved nitrogen utilization, increased carbon assimilation, improved photosynthesis, increased germination and accelerated Abreife. Yield can be further influenced by improved plant architecture (under stress and non-stress conditions), including early flowering, control of flowering for hybrid seed production, seedling growth, plant size, internode count and spacing, root growth, seed size, fruit size, Pod size, pod or ear number, number of seeds per pod or ear, seed mass, increased seed filling, reduced seed drop, reduced pod popping and stability. Other yield-related traits include seed composition such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction of nontoxic compounds, improved processability, and improved shelf life.

Plants which can be treated according to the invention are hybrid plants which already express the properties of the heterosis or of the hybrid effect, which generally leads to higher yields, higher vigor, better health and better resistance to biotic and abiotic stress factors. Such plants are typically produced by crossing an inbred male sterile parental line (the female crossover partner) with another inbred male fertile parent line (the male crossbred partner). The hybrid seed is typically harvested from the male sterile plants and sold to propagators. Pollen sterile plants can sometimes be produced (eg in maize) by delaving (ie mechanical removal of the male reproductive organs or the male flowers); however, it is more common for male sterility to be due to genetic determinants in the plant genome. In this case, especially when the desired product, as one wants to harvest from the hybrid plants, is the seeds, it is usually beneficial to ensure that the pollen fertility in hybrid plants containing the genetic determinants responsible for male sterility , completely restored. This can be achieved by ensuring that the male crossbred partners possess appropriate fertility restorers capable of restoring pollen fertility in hybrid plants containing the genetic determinants responsible for male sterility. Genetic determinants of pollen sterility may be localized in the cytoplasm. Examples of cytoplasmic male sterility (CMS) have been described, for example, for Brassica species. However, genetic determinants of pollen sterility may also be localized in the nuclear genome. Pollen sterile plants can also be obtained with methods of plant biotechnology, such as genetic engineering. A particularly convenient means of producing male-sterile plants is described in WO 89/10396, wherein, for example, a ribonuclease such as a Bamase is selectively expressed in the tapetum cells in the stamens. The fertility can then be restorated by expression of a ribonuclease inhibitor such as barstar in the tapetum cells.

Other plants or plant varieties (obtained by plant biotechnology methods, such as genetic engineering) which can be treated according to the invention are herbicide-tolerant plants, d. H. Plants tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation or by selection of plants containing a mutation conferring such herbicide tolerance.

Herbicide-tolerant plants are, for example, glyphosate-tolerant plants, i. H. Plants tolerant to the herbicide glyphosate or its salts. Thus, for example, glyphosate-tolerant plants can be obtained by transforming the plant with a gene encoding the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Examples of such EPSPS genes are the AroA gene (mutant CT7) of the bacterium Salmonella typhimurium, the CP4 gene of the bacterium Agrobacterium sp., The genes for a EPSPS from the petunia, for a EPSPS from the tomato or for a Encoding EPSPS from Eleusine. It can also be a mutated EPSPS. Glyphosate-tolerant plants can also be obtained by expressing a gene encoding a glyphosate oxidoreductase enzyme. Glyphosate-tolerant plants can also be obtained by expressing a gene encoding a glyphosate acetyltransferase enzyme. Glyphosate-tolerant plants can also be obtained by selecting plants that select naturally occurring mutations of the above mentioned genes.

Other herbicidally resistant plants are, for example, plants tolerant to herbicides which inhibit the enzyme glutamine synthase, such as bialaphos, phosphinotricin or glufosinate. Such plants can be obtained by expressing an enzyme which detoxifies the herbicide or expresses a mutant of the enzyme glutamine synthase, which is resistant to inhibition. Such an effective detoxifying enzyme is, for example, an enzyme encoding a phosphinotricin acetyltransferase (such as the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinotricin acetyltransferase have been described.

Further herbicide-tolerant plants are also plants tolerant to the herbicides which inhibit the enzyme hydroxyphenylpyruvate dioxygenase (HPPD). The hydroxyphenylpyruvate dioxygenases are enzymes that catalyze the reaction in which para-hydroxyphenylpyruvate (HPP) is converted to homogentisate. Plants that are - o - are tolerant of HPPD inhibitors, can be transformed with a gene that codes for a naturally occurring resistant HPPD enzyme, or a gene that codes for an imitated HPPD enzyme. Tolerance to HPPD inhibitors can also be achieved by transforming plants with genes encoding certain enzymes that allow the production of homogentisate despite inhibition of the native HPPD enzyme by the HPPD inhibitor. The tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding a prephenate dehydrogenase enzyme in addition to a gene encoding an HPPD-tolerant enzyme.

Other herbicide-resistant plants are plants that have been tolerated to acetolactate synthase (ALS) inhibitors. Examples of known ALS inhibitors include sulfonylurea, imidazolinone, triazolopyrimidines, pyrimidinyloxy (thio) benzoates and / or sulfonylaminocarbonyltriazolinone herbicides. It is known that various mutations in the enzyme ALS (also known as acetohydroxy acid synthase, AHAS) confer tolerance to different herbicides or groups of herbicides. The preparation of sulfonylurea tolerant plants and imidazolinone tolerant plants is described in International Publication WO 1996/033270. Other sulfonylurea and imidazolinone tolerant plants are also disclosed in e.g. WO 2007/024782 described.

Other plants which are tolerant to imidazolinone and / or sulfonylurea can be obtained by induced mutagenesis, selection in cell cultures in the presence of the herbicide or by mutation breeding.

Plants or plant varieties (obtained by plant biotechnology methods such as genetic engineering) which can also be treated according to the invention are insect-resistant transgenic plants, i. Plants that have been made resistant to attack by certain target insects.

Deoxynivalenol (DON), Nivalenol, 15-Ac-DON, 3-Ac-DON, T2- and HT2-Toxin, Fumonisins, Zearalenone, Moniliformin, Fusarin, Diaceotoxyscirpenol (especially), but not exclusively, are the following mycotoxins: DAS), beauvericin, enniatine, fusaroproliferin, fusarenol, ochratoxins, patulin, ergot alkaloids and aflatoxins, which can be caused, for example, by the following fungi: Fusarium spec., Such as Fusarium acuminatum, F. avenaceum, F. crookwellense, F. culmorum, F. graminearum (Gibberella zeae), F. equiseti, F. fujikoroi, F. musarum, F. oxysporum, F. proliferatum, F. poae, F. pseudograminearum, F. sambucinum, F. scirpi, F. semitectum, F. solani, F. sporotrichoid, F. langsethiae, F. subglutinans, F. tricinctum, F. verticillioides, and others as well as of Aspergillus spec., Penicillium spec., Claviceps purpurea, Stachybotrys spec. et al

The plants listed can be treated particularly advantageously according to the invention with the compounds of the general formula (I) the agents according to the invention. The drugs or agents specified above also apply to the treatment of these plants. Particularly emphasized is the plant treatment with the compounds or agents specifically mentioned in the present text.

According to a further aspect of the present invention, in the active substance combinations or compositions according to the invention, the ratio of the components is preferably chosen such that a synergistic effect is obtained. Here, "synergistic effect" is understood, for example, as used by Colby in the article "Calculation of the synergistic and antagonistic responses of bicarbonide combmations "(in Weeds, 1967, 15, 20-22).

According to Colby, a synergistic (over-additive) effect occurs when the actual fungicidal effect is greater than calculated. In this case, the actual observed efficiency must be greater than the value for the expected efficiency (E) calculated from the formula given below.

If

X means the efficiency when using the active substance A in an application rate of m g / ha,

Y means the efficiency when using the active ingredient B in an application rate of n g / ha,

Eg means the efficiency of the use of the active compounds A and B in application rates of m and n g / ha means and

then for a combination of 2 agents:

X - Y

E ₁ = X + Y -

100

The efficiency is determined in%. It means 0% an efficiency that corresponds to that of the control, while an efficiency of 100% means that no infestation is observed.

Another way to prove a synergistic effect is the method of Tammes (see "Isoboles, a graphic representation of synergism in pesticides" in Neth J Plant Path., 1964, 70, 73-80).

The invention is illustrated by the following examples. However, the invention is not limited to the examples. - -

applications

Puccinia triticina - field test under field conditions (winter wheat) / protective

To prepare a suitable preparation of active compound, 1 part by weight of bixafen (EC formulation) is dissolved. The PGRs are used in the form of their commercial products at their recommended dosage. It is diluted with the appropriate amount of water to the desired concentration.

• For testing for protective activity, winter wheat plants are sprayed at a defined stage on 7.5 m ² cells with the preparation of active compound in the stated application rate.

Infection with Puccinia triticina under field conditions is due to natural infection.

20 days after the application of the drug, the evaluation is carried out. In this case, 0% means an efficiency which corresponds to that of the control, while an efficiency of 100% means that no infestation is observed.
