If appropriate, the compounds according to the invention can, at certain concentrations or application rates, also be used as herbicides, safeners, growth regulators or agents to improve plant properties, or as microbicides, for example as fungicides, antimycotics, bactericides, viricides (including agents against viroids) or as agents against MLO (Mycoplasma-like organisms) and RLO (Rickettsia-like organisms). If appropriate, they can also be employed as intermediates or precursors for the synthesis of other active compounds.
All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by biotechnological and genetic engineering methods or by combinations of these methods, including the transgenic plants and including the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offshoots and seeds.
Treatment according to the invention of the plants and plant parts with the active compounds is carried out directly or by allowing the compounds to act on the surroundings, habitat or storage space by the customary treatment methods, for example by immersion, spraying, evaporation, fogging, scattering, painting on, injection and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats.
The active compounds can be converted to the customary formulations, such as solutions, emulsions, wettable powders, water- and oil-based suspensions, powders, dusts, pastes, soluble powders, soluble granules, granules for broadcasting, suspension-emulsion concentrates, natural materials impregnated with active compound, synthetic materials impregnated with active compound, fertilizers and microencapsulations in polymeric substances.
These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants and/or foam-formers. The formulations are prepared either in suitable plants or else before or during the application.
Suitable for use as auxiliaries are substances which are suitable for imparting to the composition itself and/or to preparations derived therefrom (for example spray liquors, seed dressings) particular properties such as certain technical properties and/or also particular biological properties. Typical suitable auxiliaries are: extenders, solvents and carriers.
Suitable extenders are, for example, water, polar and nonpolar organic chemical liquids, for example from the classes of the aromatic and non-aromatic hydrocarbons (such as paraffins, alkylbenzenes, alkylnaphthalenes, chlorobenzenes), the alcohols and polyols (which, if appropriate, may also be substituted, etherified and/or esterified), the ketones (such as acetone, cyclohexanone), esters (including fats and oils) and (poly)ethers, the unsubstituted and substituted amines, amides, lactams (such as N-alkylpyrrolidones) and lactones, the sulphones and sulphoxides (such as dimethyl sulphoxide).
If the extender used is water, it is also possible to employ, for example, organic solvents as auxiliary solvents.

The active substances according to the invention also exhibit a strong strengthening activity in plants. They are accordingly suitable for mobilizing intrinsic defences of plants against attack by undesirable microorganisms.
In the present context, plant-strengthening (resistance-inducing) substances are to be understood as meaning those materials which are capable of stimulating the defence system of plants such that the treated plants, on subsequent inoculation with undesirable microorganisms, exhibit extensive resistance to these microorganisms.
In the present case, undesirable microorganisms are to be understood as meaning phytopathogenic fungi, bacteria and viruses. The substances according to the invention can thus be used to protect plants from attack by the harmful pathogens mentioned for a certain period of time after the treatment. The period of time for which protection is brought about generally ranges from 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active substances.
The fact that the active substances are well tolerated by plants in the concentrations necessary for combating plant diseases makes possible treatment of aboveground plant parts, of plant propagation material and seed, and of the soil.
In this connection, the active substances according to the invention can be used particularly successfully in combating cereal diseases, such as, e.g., Puccinia species, and diseases in viticulture and in the cultivation of fruit and vegetables, such as, e.g., Botrytis, Venturia or Alternaria species.
The active substances according to the invention are also suitable for increasing the crop yield. In addition, they are of lower toxicity and are well tolerated by plants.
The active substances according to the invention can also optionally be used, in specific concentrations and application amounts, as herbicides, for affecting plant growth and for combating animal pests. They can optionally also be used as intermediates and precursors for the synthesis of additional active substances.
All plants and plant parts can be treated according to the invention. In this connection, plants are to be understood as meaning all plants and plant populations, such as desirable and undesirable wild plants or cultivated plants (including naturally occurring cultivated plants). Cultivated plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including transgenic plants and including plant varieties which may or may not be protected by laws on variety certification. Plant parts should be understood as meaning all aboveground and subsoil parts and organs of plants, such as shoot, leaf, flower and root, examples which are listed being leaves, needles, stalks, stems, flowers, fruiting bodies, fruits and seeds, and also roots, tubers and rhizomes. Plant parts also include harvested crops, and also vegetative and generative propagation material, for example cuttings, tubers, rhizomes, layers and seeds.
The treatment according to the invention of the plants and plant parts with the active substances is carried out directly or by acting on the environment, habitat or storage area thereof using conventional treatment methods, e.g. by dipping, spraying, evaporating, atomizing, scattering, spreading and, with propagation material, in particular with seeds, furthermore by coating with one or more layers.
In addition, it is possible, by the treatment according to the invention, to reduce the mycotoxin content in harvested crops and the foodstuffs and feedstuffs prepared therefrom. In this connection, mention may in particular but not exclusively be made of the following mycotoxins: deoxynivalenol (DON), nivalenol, 15-Ac-DON, 3-Ac-DON, T2 and HT2 toxin, fumonisins, zearalenone, moniliformin, fusarin, diacetoxyscirpenol (DAS), beauvericin, enniatin, 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. musanim, F. oxysporum, F. proliferatum, F. poae, F. pseudograminearum, F. sambucinum, F. scirpi, F. semitectum, F. solani, F. sporotrichoides, F. langsethiae, F. subglutinans, F. tricinctum, F. verticillioides, and others, and also by Aspergillus spec., Penicillium spec., Claviceps purpurea, Stachybotrys spec., and others.
In material protection, the substances according to the invention can be used for the protection of industrial materials from attack and destruction by undesirable microorganisms.
Industrial materials are to be understood in the present context as meaning nonliving materials which have been prepared for use in industry. For example, industrial materials which are to be protected by active substances according to the invention from microbial change or destruction can be adhesives, sizes, paper and board, textiles, leather, wood, paints and plastic articles, cooling lubricants and other materials which can be attacked or destroyed by microorganisms. In the context of the materials to be protected, mention may also be made of parts of production plants, for example cooling water circuits, which can be detrimentally affected by proliferation of microorganisms. In the context of the present invention, mention may preferably be made, as industrial materials, of adhesives, sizes, papers and boards, leather, wood, paints, cooling lubricants and heat-transfer liquids, particularly preferably of wood.
Examples which may be mentioned of microorganisms which can decompose or modify industrial materials are bacteria, fungi, yeasts, algae and slime organisms. The active substances according to the invention are preferably active against fungi, in particular moulds, wood-discolouring and wood-destroying fungi (Basidiomycetes), and against slime organisms and algae.

The compounds according to the invention can for this, depending on their respective physical and/or chemical properties, be converted into the standard formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, very fine encapsulations in polymeric substances and in coating materials for seed, and also ULV cold- and hot-fogging formulations.
These formulations are prepared in a known way, e.g. by mixing the active substances with extenders, that is liquid solvents, liquefied gases under pressure and/or solid carriers, optionally with the use of surface-active agents, that is emulsifiers and/or dispersants and/or foaming agents. In the case of the use of water as extender, use may also be made, e.g., of organic solvents as cosolvents. Possible liquid solvents are essentially: aromatic hydrocarbons, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatic hydrocarbons or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, e.g. petroleum fractions, alcohols, such as butanol or glycol, and the ethers and esters thereof, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water. Liquefied gaseous extenders or carriers are to be understood as meaning those liquids which are in the gas form at standard temperature and at standard pressure, e.g. aerosol propellants, such as halogenated hydrocarbons and also butane, propane, nitrogen and carbon dioxide. Possible solid carriers are, e.g., ground natural minerals, such as kaolins, argillaceous earths, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly dispersed silica, aluminium oxide and silicates. Possible solid carriers for granules are, e.g., broken and fractionated natural rocks, such as calcite, pumice, marble, sepiolite or dolomite, and also synthetic granules formed from inorganic and organic dusts, and also granules formed from organic material, such as sawdust, coconut shells, maize cobs and tobacco stalks. Possible emulsifiers and/or foaming agents are, e.g., nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, e.g. alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, and also protein hydrolysates. Possible dispersants are, e.g., lignosulphite waste liquors and methylcellulose.
Use may be made, in the formulations, of stickers, such as carboxymethylcellulose, natural and synthetic polymers in the powder, granule or latex form, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids. Other possible additives are mineral and vegetable oils.
Use may also be made of colorants, such as inorganic pigments, e.g. iron oxide, titanium oxide, Prussian blue, and organic colorants, such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and trace elements, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations generally comprise between 0.1 and 95% by weight of active substance, preferably between 0.5 and 90%.
The formulations described above can be used in a method according to the invention for combating undesirable microorganisms, in which the compounds according to the invention are applied to the microorganisms and/or to the habitat thereof.
The combating of phytopathogenic fungi by the treatment of the seed of plants has been known for a long time and is the subject-matter of continuous improvements. Nevertheless, a series of problems arises in the treatment of seed, which problems may not always be satisfactorily solved. Thus, it is desirable to develop methods for protecting the seed and the germinating plant which render superfluous or at least markedly reduce the additional application of plant protection compositions after sowing or after emergence of the plants. It is furthermore desirable to optimize the amount of the active substance used, so that the seed and the germinating plant are given the best possible protection against attack by phytopathogenic fungi but without the plant itself being damaged by the active substance used. In particular, methods for the treatment of 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 expenditure of plant protection compositions.
The present invention therefore also relates in particular to a method for the protection of seed and germinating plants from attack by phytopathogenic fungi, by treating the seed with a composition according to the invention.
The invention likewise relates to the use of the compositions according to the invention for the treatment of seed to protect the seed and the germinating plant from phytopathogenic fungi.
Furthermore, the invention relates to seed which has been treated with a composition according to the invention in order to protect from phytopathogenic fungi.
One of the advantages of the present invention is that, because of the particular systemic properties of the compositions according to the invention, the treatment of the seed with these compositions not only protects the seed itself from phytopathogenic fungi but also protects the plants resulting therefrom after emergence from phytopathogenic fungi. In this way, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.
It is likewise to be regarded as advantageous that the mixtures according to the invention can in particular also be used with transgenic seed.
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. The seed concerned in this connection is in particular seed of cereals (such as wheat, barley, rye, millet and oats), maize, cotton, soya, rice, potatoes, sunflowers, beans, coffee, beet (e.g., sugarbeet and forage beet), peanuts, vegetables (such as tomatoes, cucumbers, onions and lettuce), lawns and ornamental plants. The treatment of the seed of cereals (such as wheat, barley, rye and oats), maize and rice is of particular importance.
In the context of the present invention, the composition according to the invention is applied to the seed alone or in a suitable formulation. Preferably, the seed is treated in a condition sufficiently stable for no damage to occur during the treatment. In general, the treatment of the seed can be carried out at any point in time between harvesting and sowing. Use is usually made of seed which has been separated from the plant and freed from pods, shells, stalks, skins, hairs or fruit flesh. Thus, it is possible, for example, to use seed which has been harvested, cleaned and dried up to a moisture content of less than 15% by weight. Alternatively, it is also possible to use seed which, after drying, has been treated, e.g. with water, and then dried again.
In general, care must be taken, in the treatment of the seed, that the amount of the composition according to the invention and/or of additional additives applied to the seed is chosen so that the germination of the seed is not impaired or that the plant resulting therefrom is not damaged. This is to be taken into consideration in particular with active substances which may show phytotoxic effects at certain application rates.
The compositions according to the invention can be applied immediately, thus without comprising additional components and without having been diluted. It is generally preferable to apply the compositions to the seed in the form of a suitable formulation. Suitable formulations and methods for seed treatment are known to a person skilled in the art and are described, e.g., in the following documents: U.S. Pat. No. 4,272,417 A, U.S. Pat. No. 4,245,432 A, U.S. Pat. No. 4,808,430 A, U.S. Pat. No. 5,876,739 A, US 2003/0176428 A1, WO 2002/080675 A1, WO 2002/028186 A2.
The active substance combinations which can be used according to the invention can be converted into the usual seed dressing formulations, such as solutions, emulsions, suspensions, powders, foams, slurries or other coating materials for seed, and also ULV formulations.
These formulations are prepared in a known way by mixing the active substances or active substance combinations with conventional additives, such as, for example, conventional extenders and also solvents or diluents, colorants, wetting agents, dispersants, emulsifiers, antifoaming agents, preservatives, secondary thickeners, adhesives, gibberellins and also water.
Suitable colorants which may be present in the seed dressing formulations which can be used according to the invention comprise all colorants conventional for such purposes. In this connection, use may be made both of pigments, which are sparingly soluble in water, and dyes, which are soluble in water. Mention may be made, as examples, of the colorants known under the descriptions Rhodamine B, C.I. Pigment Red 112 and C.I. Solvent Red 1.
Possible wetting agents which can be present in the seed dressing formulations which can be used according to the invention comprise all substances which promote wetting and are conventional in the formulation of agrochemical active substances. Use may preferably be made of alkylnaphthalenesulphonates, such as diisopropyl- or diisobutylnaphthalenesulphonates.
Suitable dispersants and/or emulsifiers which may be present in the seed dressing formulations which can be used according to the invention comprise all nonionic, anionic and cationic dispersants conventional in the formulation of agrochemical active substances. Use may preferably be made of nonionic or anionic dispersants or mixtures of nonionic or anionic dispersants. Mention may in particular be made, as suitable nonionic dispersants, of ethylene oxide/propylene oxide block polymers, alkylphenol polyglycol ethers and also tristyrylphenol polyglycol ethers, and the phosphated or sulphated derivatives thereof. Suitable anionic dispersants are in particular lignosulphonates, polyacrylic acid salts and arylsulphonate/formaldehyde condensates.
Antifoaming agents which may be present in the seed dressing formulations which can be used according to the invention comprise all foam-inhibiting substances conventional in the formulation of agrochemical active substances. Use may preferably be made of silicone defoaming agents and magnesium stearate.
Preservatives which may be present in the seed dressing formulations which can be used according to the invention comprise all substances which can be used in agrochemical compositions for such purposes. Mention may be made, by way of example, of dichlorophen and benzyl alcohol hemiformal.
Possible secondary thickeners which may be present in the seed dressing formulations which can be used according to the invention comprise all substances which can be used in agrochemical compositions for such purposes. Preferably suitable are cellulose derivatives, acrylic acid derivatives, xanthan, modified clays and highly dispersed silica.
Possible adhesives which may be present in the seed dressing formulations which can be used according to the invention comprise all conventional binders which can be used in seed dressings. Mention may preferably be made of polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and tylose.
Possible gibberellins which may be present in the seed dressing formulations which can be used according to the invention preferably comprise gibberellins A1, A3 (=gibberellic acid), A4 and A7; use is particularly preferably made of gibberellic acid. Gibberellins are known (cf. R. Wegler, “Chemie der Pflanzenschutz- and Schädlingsbekämpfungsmittel” [Chemistry of Plant Protection and Pest Control Agents], 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 diluting with water, for the treatment of seed of the most varied species. Thus, the concentrates or the compositions which can be obtained therefrom by diluting with water can be used for the dressing of the seed of cereals, such as wheat, barley, rye, oats and triticale, and also the seed of maize, rice, rape, peas, beans, cotton, sunflowers and beet, or also of vegetable seed of the most varied natures. The seed dressing formulations which can be used according to the invention or the diluted compositions thereof can also be used for the dressing of seed of transgenic plants. In this connection, additional synergistic effects may also occur in interaction with the substances formed by expression.
All mixing devices which can be conventionally used for dressing are suitable for the treatment of seed with the seed dressing formulations which can be used according to the invention or the compositions prepared therefrom by addition of water. Specifically, the dressing procedure is such that the seed is introduced into a mixer, the amount of seed dressing formulation desired each time is added, either as such or after prior dilution with water, and mixing is carried out until the formulation is uniformly distributed over the seed. If appropriate, a drying operation follows.
The application rate of the seed dressing formulations which can be used according to the invention can be varied within a relatively wide range. It depends on the respective content of the active substances in the formulations and on the seed. The application rates of active substance combination are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 15 g per kilogram of seed.
The compounds according to the invention can be used, as such or in their formulations, also in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, in order thus, e.g., to broaden the spectrum of activity or to prevent the development of resistance.
A mixture with other known active substances, such as herbicides, or with fertilizers and growth regulators, safeners or semiochemicals is also possible.
In addition, the compounds of the formula (I) according to the invention also exhibit very good antimycotic activities. They have a very broad spectrum of antimycotic activity, in particular against dermatophytes and budding fungi, moulds and diphasic fungi (e.g. against Candida species, such as Candida albicans, Candida glabrata), and also Epidermophyton floccosum, Aspergillus species, such as Aspergillus niger and Aspergillus fumigatus, Trichophyton species, such as Trichophyton mentagrophytes, Microsporon species, such as Microsporon canis and audouinii. The enumeration of these fungi does not represent in any way a limitation on the mycotic spectrum which can be included but has only an illustrative nature.
The compounds according to the invention can accordingly be used both in medicinal and in nonmedicinal applications.
The active substances can be applied as such, in the form of their formulations or in the form of the application forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application takes place in standard fashion, e.g. by pouring, spraying, atomizing, scattering, dusting, foaming, spreading, and the like. It is furthermore possible to apply the active substances by the ultra-low-volume method or to inject the active substance composition or the active substance itself into the soil.
The seed of the plant can also be treated.
When the compound according to the invention are used as fungicides, the application rates can be varied within a relatively wide range depending on the type of application. In the treatment of plant parts, the application rates of active substance are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1000 g/ha. In seed treatment, the application rates of active substance are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 10 g per kilogram of seed. In soil treatment, the application rates of active substance are generally between 0.1 and 10 000 g/ha, preferably between 1 and 5000 g/ha.
As already mentioned above, all plants and the parts thereof can be treated according to the invention. In a preferred embodiment, plant species and plant varieties occurring in the wild or obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and the parts thereof are treated. In an additional preferred embodiment, transgenic plants and plant varieties obtained by genetic engineering methods, optionally in combination with conventional methods, (genetically modified organisms) and the parts thereof are treated. The term “parts” or “parts of plants” or “plant parts” was explained above.
The method of treatment according to the invention can be used in the treatment of genetically modified organisms (GMOs), e.g. plants or seeds. Genetically modified plants (or transgenic plants) are plants of which a heterologous gene has been stably integrated into the genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using, for example, antisense technology, cosuppression technology or RNA interference—RNAi technology). A heterologous gene that is located in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.
Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the active substances and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, bigger fruits, larger plant height, greener leaf colour, earlier flowering, higher quality and/or a higher nutritional value of the harvested products, higher sugar concentration within the fruits, better storage stability and/or processability of the harvested products are possible, which exceed the effects which were actually to be expected.
At certain application rates, the active substance combinations according to the invention may also have a strengthening effect in plants. Accordingly, they are suitable for mobilizing the defence system of the plant against attack by unwanted phytopathogenic fungi and/or microorganisms and/or viruses. This may, if appropriate, be one of the reasons for the enhanced activity of the combinations according to the invention, for example against fungi. Plant-strengthening (resistance-inducing) substances are to be understood as meaning, in the present context, those substances or combinations of substances which are capable of stimulating the defence system of plants in such a way that, when subsequently inoculated with unwanted phytopathogenic fungi and/or microorganisms and/or viruses, the treated plants display a substantial degree of resistance to these unwanted phytopathogenic fungi and/or microorganisms and/or viruses. In the present case, unwanted phytopathogenic fungi and/or microorganisms and/or viruses are to be understood as meaning phytopathogenic fungi, bacteria and viruses. Thus, the substances according to the invention can be employed for protecting plants against attack by the abovementioned pathogens within a certain period of time after the treatment. The period of time within which protection is effected generally extends from 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active substances.
Plants and plant cultivars which are preferably treated according to the invention include all plants which have genetic material which imparts particularly advantageous, useful traits to these plants (whether obtained by breeding and/or biotechnological means).
Plants and plant cultivars which are also preferably treated according to the invention are resistant against one or more biotic stresses, i.e. the said plants show a better defence against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
Plants and plant cultivars which may also be treated according to the invention are those plants which are resistant to one or more abiotic stresses. Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, flooding, increased soil salinity, increased mineral exposure, ozone exposure, high light exposure, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients, shade avoidance.
Plants and plant cultivars which may also be treated according to the invention are those plants characterized by enhanced yield characteristics. Increased yield in the said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can furthermore be affected by improved plant architecture (under stress and non-stress conditions), including early flowering, flowering control for hybrid seed production, seedling vigour, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pot dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processability and better storage stability.
Plants that may be treated according to the invention are hybrid plants that already express the characteristics of heterosis or hybrid vigour which results in generally higher yield, vigour, health and resistance towards biotic and abiotic stress factors. Such plants are typically made by crossing an inbred male-sterile parent line (the female parent) with another inbred male-fertile parent line (the male parent). Hybrid seed is typically harvested from the male sterile plants and sold to growers. Male sterile plants can sometimes (e.g. in maize) be produced by detasseling (i.e. the mechanical removal of the male reproductive organs or male flowers) but, more typically, male sterility is the result of genetic determinants in the plant genome. In that case, and especially when seed is the desired product to be harvested from the hybrid plants, it is typically useful to ensure that male fertility in hybrid plants that contain the genetic determinants responsible for male sterility is fully restored. This can be accomplished by ensuring that the male parents have appropriate fertility restorer genes which are capable of restoring the male fertility in hybrid plants that contain the genetic determinants responsible for male sterility. Genetic determinants for male sterility may be located in the cytoplasm. Examples of cytoplasmic male sterility (CMS) were for instance described in Brassica species (WO 1992/005251, WO 1995/009910, WO 1998/27806, WO 2005/002324, WO 2006/021972 and U.S. Pat. No. 6,229,072). However, genetic determinants for male sterility can also be located in the nuclear genome. Male sterile plants can also be obtained by plant biotechnology methods, such as genetic engineering. A particularly useful means of obtaining male-sterile plants is described in WO 89/10396 in which, for example, a ribonuclease, such as barnase, is selectively expressed in the tapetum cells in the stamens. Fertility can then be restored by expression in the tapetum cells of a ribonuclease inhibitor, such as barstar (e.g. WO 1991/002069).
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance.
Herbicide-tolerant plants are for example glyphosate-tolerant plants, i.e. plants made tolerant to the herbicide glyphosate or salts thereof. 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 (Comai et al., Science (1983), 221, 370-371), the CP4 gene of the bacterium Agrobacterium sp. (Barry et al., Curr. Topics Plant Physiol. (1992), 7, 139-145), the genes encoding a petunia EPSPS (Shah et al., Science (1986), 233, 478-481), a tomato EPSPS (Gasser et al., J. Biol. Chem. (1988), 263, 4280-4289) or an eleusine EPSPS (WO 2001/66704). It can also be a mutated EPSPS as described in for example EP-A 0837944, WO 2000/066746, WO 2000/066747 or WO 2002/026995. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxidoreductase enzyme as described in U.S. Pat. No. 5,776,760 and U.S. Pat. No. 5,463,175. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate acetyl transferase enzyme as described in for example WO 2002/036782, WO 2003/092360, WO 2005/012515 and WO 2007/024782. Glyphosate-tolerant plants can also be obtained by selecting plants containing naturally-occurring mutations of the abovementioned genes, as described in for example WO 2001/024615 or WO 2003/013226.
Other herbicide-resistant plants are for example plants that are made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinotricin or glufosinate. Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant of the glutamine synthase enzyme that is resistant to inhibition. One such efficient detoxifying enzyme is an enzyme encoding a phosphinotricin acetyltransferase (such as the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinotricin acetyltransferase are for example described in U.S. Pat. No. 5,561,236; U.S. Pat. No. 5,648,477; U.S. Pat. No. 5,646,024; U.S. Pat. No. 5,273,894; U.S. Pat. No. 5,637,489; U.S. Pat. No. 5,276,268; U.S. Pat. No. 5,739,082; U.S. Pat. No. 5,908,810 and U.S. Pat. No. 7,112,665.
Further herbicide-tolerant plants are also plants that are made tolerant to the herbicides inhibiting the enzyme hydroxyphenylpyruvatedioxygenase (HPPD). Hydroxyphenylpyruvatedioxygenases are enzymes that catalyse the reaction in which para-hydroxyphenylpyruvate (HPP) is transformed into homogentisate. Plants tolerant to HPPD inhibitors can be transformed with a gene encoding a naturally occurring resistant HPPD enzyme, or a gene encoding a mutated HPPD enzyme as described in WO 1996/038567, WO 1999/024585 and WO 1999/024586. Tolerance to HPPD inhibitors can also be obtained by transforming plants with genes encoding certain enzymes enabling the formation of homogentisate despite the inhibition of the native HPPD enzyme by the HPPD inhibitor. Such plants and genes are described in WO 1999/034008 and WO 2002/36787. Tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate dehydrogenase in addition to a gene encoding an HPPD-tolerant enzyme, as described in WO 2004/024928.
Further herbicide-resistant plants are plants that are made tolerant to acetolactate synthase (ALS) inhibitors. Known ALS inhibitors include, for example, sulphonylurea, imidazolinone, triazolopyrimidines, pyrimidinyloxy(thio)benzoates and/or sulphonylaminocarbonyltriazolinone herbicides. Different mutations in the ALS enzyme (also known as acetohydroxyacid synthase, AHAS) are known to confer tolerance to different herbicides and groups of herbicides, as described for example in Tranel and Wright, Weed Science (2002), 50, 700-712, but also in U.S. Pat. No. 5,605,011, U.S. Pat. No. 5,378,824, U.S. Pat. No. 5,141,870 and U.S. Pat. No. 5,013,659. The production of sulphonylurea-tolerant plants and imidazolinone-tolerant plants is described in U.S. Pat. No. 5,605,011; U.S. Pat. No. 5,013,659; U.S. Pat. No. 5,141,870; U.S. Pat. No. 5,767,361; U.S. Pat. No. 5,731,180; U.S. Pat. No. 5,304,732; U.S. Pat. No. 4,761,373; U.S. Pat. No. 5,331,107; U.S. Pat. No. 5,928,937; and U.S. Pat. No. 5,378,824; and international publication WO 1996/033270. Other imidazolinone-tolerant plants are also described in, for example, WO 2004/040012, WO 2004/106529, WO 2005/020673, WO 2005/093093, WO 2006/007373, WO 2006/015376, WO 2006/024351 and WO 2006/060634. Further sulphonylurea- and imidazolinone-tolerant plants are also described in, for example, WO 2007/024782.
Other plants tolerant to imidazolinone and/or sulphonylurea can be obtained by induced mutagenesis, selection in cell cultures in the presence of herbicide or mutation breeding as described for example for soybeans in U.S. Pat. No. 5,084,082, for rice in WO 1997/41218, for sugarbeet in U.S. Pat. No. 5,773,702 and WO 1999/057965, for lettuce in U.S. Pat. No. 5,198,599, or for sunflower in WO 2001/065922.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are insect-resistant transgenic plants, i.e. plants made resistant to attack by certain target insects. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such insect resistance.
An “insect-resistant transgenic plant”, as used herein, includes any plant containing at least one transgene comprising a coding sequence encoding:
Of course, an insect-resistant transgenic plant, as used herein, also includes any plant comprising a combination of genes encoding the proteins of any one of the above classes 1 to 8. In one embodiment, an insect-resistant plant contains more than one transgene encoding a protein of any one of the above classes 1 to 8, to expand the range of target insect species affected or to delay insect resistance development to the plants by using different proteins insecticidal to the same target insect species but having a different mode of action, such as binding to different receptor binding sites in the insect.

Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance. Particularly useful stress tolerance plants include:

Plants or plant cultivars (obtained by plant biotechnology methods, such as genetic engineering) which may also be treated according to the invention are plants, such as cotton plants, with altered fibre characteristics. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such altered fibre characteristics and include:
Plants or plant cultivars (obtained by plant biotechnology methods, such as genetic engineering) which may also be treated according to the invention are plants, such as oilseed rape or related Brassica plants, with altered oil profile characteristics. Such plants can be obtained by genetic transformation or by selection of plants containing a mutation imparting such altered oil characteristics and include:

Nucotn 33B® (cotton), NatureGard® (for example maize), Protects® and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soybean varieties which are sold under the following trade names: Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soybean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinone) and SCS® (tolerance to sulphonylurea), for example maize. Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned include the varieties sold under the name Clearfield® (for example maize).
Particularly useful transgenic plants which may be treated according to the invention are plants containing transformation events, or a combination of transformation events, that are listed for example in the databases from various national or regional regulatory agencies (see for example http://gmoinfo.jrc.it/gmp_browse.aspx and http://www.agbios.com/dbase.php).
