Patent Application
20150257387
The present invention relates to a pesticide composition intended for protecting plants, crops or seeds against fungal diseases or insect damages, and the corresponding methods of protection by application of the said composition. More precisely, the subject of the present invention is a pesticide composition based on a tetrazolyloxime derivative and a fungicide or an insecticide active substance or compound.
As regards pesticide activity, in particular for the protection of crops, one of the problems at the heart of the research studies carried out in this technical field is the improvement of performances, in particular in terms of biological activity and in particular in terms of maintaining such an activity over time.
The present invention provides a pesticide composition which can be used, in particular by the farmer, for controlling the pest infesting crops and in particular for controlling insects or diseases.
The pesticide compounds useful for the protection of plants must be endowed with an ecotoxicity which is reduced to the minimum. As far as possible, they should not be dangerous or toxic to the operator during use. The economic factor should of course not be overlooked in the search for novel pesticide agents.
The present invention advantageously provides a pesticide composition which is completely high-performing in particular as regards its efficacy against pests and the perenniallity of this efficacy so as to be able to reduce the doses of chemical products spread in the environment for combating pest damages or attacks of plants or crops.
The invention provides a pesticide composition capable to be more active and active for longer, and which therefore has a lower dose, but which is also less toxic, in particular in the treatment of plants and particularly the foliar and seed treatments of fungal diseases or the control of insects, for example, of cereals, cotton, peanut, bean, beet, canola, Solanaceae, grapevine, vegetables, lucerne, soybean, market garden crops, turf, wood or horticultural plants.
The composition according to the invention allows controlling a broad variety of insects or fungi. For example, the pesticide composition according to the invention exhibits an improved efficacy against fungus like Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Basidiomycetes, Deuteromycetes and Ascomycetes.
All these objectives or advantages, among others, were achieved by finding a pesticide composition comprising a tetrazolyloxime derivative and a fungicide or an insecticide compound. Such a composition surprisingly and unexpectedly allows a very high and perennial anti-fungal or insecticide efficacy against a broad spectrum of insects or fungi and in particular against those responsible for diseases or damages of crops. Other insect pests or diseases of crops can be controlled with the pesticide composition according to the invention.
The pesticide composition according to the invention may also be used for the treatment of bacterial or virus diseases.
Insects or nematodes that can be controlled with the pesticide composition according to the invention include a broad variety of these damaging organisms.

According to another aspect of the present invention, in the pesticide composition according to the invention, the compound ratio A/B can be advantageously selected so as to produce a synergistic effect. The term synergistic effect is understood to mean in particular that defined by Colby in an article entitled “Calculation of the synergistic and antagonistic responses of herbicide combinations” Weeds, (1967), 15, pages 20-22.
The latter article mentions the formula:
wherein E represents the expected percentage of inhibition of the pest for the combination of the two compounds at defined doses (for example equal to x and y respectively), X is the percentage of inhibition observed for the pest by compound A at a defined dose (equal to x), Y is the percentage of inhibition observed for the pest by compound B at a defined dose (equal to y). When the percentage of inhibition observed for the combination is greater than E, there is a synergistic effect.
The term “synergistic effect” also means the effect defined by application of the Tammes method, “Isoboles, a graphic representation of synergism in pesticides”, Netherlands Journal of Plant Pathology, 70(1964), pages 73-80.
According to another aspect of the present invention, in the pesticide composition according to the invention, the compound ratio A/B/C can be advantageously selected so as to produce a synergistic effect. The term synergistic effect is understood to mean in particular that defined by Colby in an article entitled “Calculation of the synergistic and antagonistic responses of herbicide combinations” Weeds, (1967), 15, pages 20-22.

The term “synergistic effect” also means the effect defined by application of the Tammes method, “Isoboles, a graphic representation of synergism in pesticides”, Netherlands Journal of Plant Pathology, 70(1964), pages 73-80.
Synergistic compositions comprising further active substances also form part of the present invention, the associated synergistic effect can be evidenced in a similar manner.
The pesticide composition according to the invention may comprise from 0.00001 to 100%, preferably from 0.001 to 80%, of active compounds, whether these compounds are combined or whether they are in the form of two or more active ingredients used separately. More generally, the pesticide composition according to the invention may eventually also comprise one or more other active substances selected from fungicide, herbicide, insecticide or plant growth regulator active compounds.
In addition to these additional active agents, the pesticide composition according to the invention may also comprise any other adjuvants or auxiliary agent useful in plant protection formulations such as, for example, an agriculturally suitable inert carrier and optionally an agriculturally suitable surfactant.
For its practical use, the pesticide composition according to the invention can be used alone or in formulations containing one or the other of the active ingredients or alternatively both of them together, in combination or association with one or more other compatible components which are, for example, solid or liquid fillers or diluents, adjuvants, surfactants or equivalents, which are suitable for the desired use and which are acceptable for uses in agriculture. The formulations can be of any type known in the sector that is suitable for application onto all types of cultures or crops. These formulations, which can be prepared in any manner known by the skilled person, also form part of the invention.
The formulations may also contain ingredients of other types, such as protective colloids, adhesives, thickeners, thixotropic agents, penetrating agents, oils for spraying, stabilisers, preserving agents (in particular mould-proofing or biocide agents), sequestering or chelating agents or the like. More generally, the compounds used in the invention can be combined with any solid or liquid additives corresponding to the usual formulation techniques. The term “filler” means an organic or inorganic, natural or synthetic component with which the active components are combined to facilitate its application, for example, onto the plants, the seeds or the soil. This filler is consequently generally inert and it must be acceptable (for example acceptable for agronomic uses, in particular for treating plants).
The filler can be solid, for example clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers (for example ammonium salts), natural soil minerals, such as kaolins, clays, talc, lime, quartz, attapulgite, montmorillonite, bentonite or diatomaceous earths or synthetic minerals, such as silica, alumina or silicates, in particular aluminium or magnesium silicates.
The solid fillers which are suitable for granules are as follows: natural, crushed or broken rocks, such as calcite, marble, pumice, sepiolite and dolomite; synthetic granules of inorganic or organic flours; granules of organic material such as sawdust, coconut shell, corn ear or envelope or tobacco stem; kieselguhr, tricalcium phosphate, powdered cork or adsorbent carbon black; water-soluble polymers, resins, waxes; or solid fertilizers. Such composition may, if so desired, contain one or more compatible agents such as wetting agents, dispersing agents, emulsifiers or colourings which, when they are solid, may also act as diluents.
The fillers may also be liquid, for example: water, alcohols, in particular butanol or glycol, as well as ethers or esters thereof, in particular methyl glycol acetate; ketones, in particular acetone, cyclohexanone, methyl ethyl ketone, methyl isobutyl ketone or isophorone; petroleum fractions such as paraffinic or aromatic hydrocarbons, in particular xylenes or alkylnaphthalenes; mineral or plant oils; aliphatic chlorohydrocarbons, in particular trichloroethane or methylene chloride; aromatic chlorohydrocarbons, in particular chlorobenzenes; water-soluble or highly polar solvents such as dimethylformamide, dimethyl sulphoxide, N,N-dimethyl-acetamide or N-methylpyrrolidone; N-octylpyrrolidone, liquefied gases; or the like, whether they are taken separately or as a mixture.
The surfactant can be an emulsifier, a dispersing agent or a wetting agent, of ionic or nonionic type or a mixture of these surfactants. Among those surfactants there are used, for example, polyacrylic acid salts, lignosulphonic acid salts, phenolsulphonic or naphthalenesulphonic acid salts, polycondensates of ethylene oxide with fatty alcohols or fatty acids or fatty esters or fatty amines, substituted phenols (in particular alkylphenols or arylphenols), ester-salts of sulphosuccinic acid, taurine derivatives (in particular alkyl taurates), phosphoric esters of alcohols or of polycondensates of ethylene oxide with phenols, fatty acid esters with polyols or sulphate, sulphonate or phosphate functional derivatives of the compounds described above. The presence of at least one surfactant is generally essential when the active ingredients and/or the inert filler are insoluble or only sparingly soluble in water and when the filler for the said composition to be applied is water.
The formulations may also contain other additives such as adhesives or dyes. Adhesives such as carboxymethylcellulose or natural or synthetic polymers in the form of powders, granules or matrices, such as gum arabic, latex, polyvinylpyrrolidone, polyvinyl alcohol or polyvinyl acetate, natural phospholipids, such as cephalins or lecithins or synthetic phospholipids can be used in the formulations. It is possible to use colourings such as inorganic pigments, such as, for example: iron oxides, titanium oxides, Prussian blue; organic colouring stuffs, such as those of the alizarin, azo or metal phthalocyanin type; or of trace elements such as iron, manganese, boron, copper, cobalt, molybdenum or zinc salts.
The form of the pesticide composition according to the invention can be selected in a large number of formulations, such as aerosol dispenser; suspension of capsules; cold fogging concentrate; dustable powder; emulsifiable concentrate; aqueous/aqueous type emulsion; oil/inverse type emulsion; encapsulated granule; fine granule; suspension concentrate for seed treatment; compressed gas; gas generating product; granule; hot fogging concentrate; macrogranule; microgranule; oil-dispersible powder; oil miscible suspension concentrate; oil-miscible liquid; paste; plant rodlet; powder for dry seed treatment; seeds coated with a pesticide; smoke maydle; smoke cartridge; smoke generator; smoke pellet; smoke rodlet; smoke tablet; smoke tin; soluble concentrate; soluble powder; solution for seed treatment; suspension concentrate (=flowable concentrate); ultra low volume liquid; ultra low volume suspension; vapour releasing product; water-dispersible granules or tablets; water dispersible powder for slurry treatment; water-soluble granules or tablets; water-soluble powder for seed treatment; wettable powder.
The pesticide composition according to the present invention covers not only the compositions which are ready to be applied to the crop by means of a suitable device, such as a spraying device, but also the commercial concentrated composition which have to be diluted before application to the crop.
The pesticide composition herein described is used in general for application to growing plants or to sites where crops are grown or intended to grow or for the treatment, coating or film-coating of seeds.
According to the present invention, seeds may comprise any propagation materials, like for example seeds, fruit, tubers, grains, roots, rhizomes, parts of plants.
The pesticide composition according to the invention may also be applied to the vegetation and in particular to the leaves infested or capable of being infested with the phytopathogenic fungi or damaged by insects. Another method of applying the pesticide composition according to the invention is to add a formulation containing the active ingredients to the irrigation water.
According to another object of the present invention, there is provided a method for controlling the phytopathogenic fungi or damaging insects of plants, crops or seeds, characterized in that an agronomically effective and substantially non-phytotoxic quantity of a pesticide composition according to the invention is applied as seed treatment, foliar application, stem application, drench or drip application (chemigation) to the seed, the plant or to the fruit of the plant or to soil or to inert substrate (e.g. inorganic substrates like sand, rockwool, glasswool; expanded minerals like perlite, vermiculite, zeolite or expanded clay), Pumice, Pyroclastic materials or stuff, synthetic organic substrates (e.g. polyurethane) organic substrates (e.g. peat, composts, tree waste products like coir, wood fibre or chips, tree bark) or to a liquid substrate (e.g. floating hydroponic systems, Nutrient Film Technique, Aeroponics) wherein the plant is growing or wherein it is desired to grow.
The expression “are applied to the plants to be treated” is understood to mean, for the purposes of the present invention, that the pesticide composition which is the subject of the invention can be applied by means of various methods of treatment such as:
The method according to the invention may either be a curing, preventing or eradicating method.
In this method, a composition used can be prepared beforehand by mixing the two or more active compounds according to the invention.
According to an alternative of such a method, it is also possible to apply simultaneously, successively or separately compounds (A), (B), (C) or (D) so as to have the conjugated (A)/(B) /(C)/(D) effects, of distinct compositions each containing one or more active ingredients (A), (B), (C) or (D).
The dose of active compound usually applied in the method of treatment according to the invention is generally and advantageously
The doses herein indicated are given as illustrative Examples of method according to the invention. A person skilled in the art will know how to adapt the application doses, notably according to the nature of the plant or crop to be treated.
Under specific conditions, for example according to the nature of the phytopathogenic fungus to be treated or insect to control, a lower dose may offer adequate protection. Certain climatic conditions, resistance or other factors like the nature of the phytopathogenic fungi or damaging insect to be eliminated or the degree of infestation, for example, of the plants with these fungi, may require higher doses of combined active ingredients.
The optimum dose usually depends on several factors, for example on the type of phytopathogenic fungus to be treated or insect to control, on the type or level of development of the infested plant, on the density of vegetation or alternatively on the method of application.
Without it being limiting, the crop treated with the pesticide composition or combination according to the invention is, for example, grapevine, but this could be cereals, vegetables, lucerne, soybean, market garden crops, turf, wood, tree or horticultural plants.
The method of treatment according to the invention may also be useful to treat propagation material such as tubers or rhizomes, but also seeds, seedlings or seedlings pricking out and plants or plants pricking out. This method of treatment may also be useful to treat roots. The method of treatment according to the invention may also be useful to treat the over-ground parts of the plant such as trunks, stems or stalks, leaves, flowers and fruit of the concerned plant.
According to the invention all plants and plant parts can be treated. By plants is meant all plants and plant populations such as desirable and undesirable wild plants, cultivars and plant varieties (whether or not protectable by plant variety or plant breeder's rights). Cultivars and plant varieties can be plants obtained by conventional propagation and breeding methods which can be assisted or supplemented by one or more biotechnological methods such as by use of double haploids, protoplast fusion, random and directed mutagenesis, molecular or genetic markers or by bioengineering and genetic engineering methods. By plant parts is meant all above ground and below ground parts and organs of plants such as shoot, leaf, blossom and root, whereby for example leaves, needles, stems, branches, blossoms, fruiting bodies, fruits and seed as well as roots, corms and rhizomes are listed. Crops and vegetative and generative propagating material, for example cuttings, corms, rhizomes, runners and seeds also belong to plant parts.
Among the plants that can be protected by the method according to the invention, mention may be made of major field crops like corn, soybean, cotton, Brassica oilseeds such as Brassica napus (e.g. canola), Brassica rapa, B. juncea (e.g. mustard) and Brassica carinata, rice, wheat, sugarbeet, sugarcane, oats, rye, barley, millet, triticale, flax, vine and various fruits and vegetables of various botanical taxa such as Rosaceae sp. (for instance pip fruit such as apples and pears, but also stone fruit such as apricots, cherries, almonds and peaches, berry fruits such as strawberries), Ribesioidae sp., Juglandaceae sp., Betulaceae sp., Anacardiaceae sp., Fagaceae sp., Moraceae sp., Oleaceae sp., Actinidaceae sp., Lauraceae sp., Musaceae sp. (for instance banana trees and plantings), Rubiaceae sp. (for instance coffee), Theaceae sp., Sterculiceae sp., Rutaceae sp. (for instance lemons, oranges and grapefruit); Solanaceae sp. (for instance tomatoes, potatoes, peppers, eggplant), Liliaceae sp., Compositiae sp. (for instance lettuce, artichoke and chicory-including root chicory, endive or common chicory), Umbelliferae sp. (for instance carrot, parsley, celery and celeriac), Cucurbitaceae sp. (for instance cucumber—including pickling cucumber, squash, watermelon, gourds and melons), Alliaceae sp. (for instance onions and leek), Cruciferae sp. (for instance white cabbage, red cabbage, broccoli, cauliflower, brussel sprouts, pak Choi, kohlrabi, radish, horseradish, cress, Chinese cabbage), Leguminosae sp. (for instance peanuts, peas and beans beans—such as climbing beans and broad beans), Chenopodiaceae sp. (for instance mangold, spinach beet, spinach, beetroots), Malvaceae (for instance okra), Asparagaceae (for instance asparagus); horticultural and forest crops; ornamental plants; as well as genetically modified homologues of these crops.
The product, composition and method of treatment according to the invention can be used in the treatment of genetically modified organisms (GMOs), e.g. plants or seeds. Genetically modified plants (or transgenic plants) are plants of which a heterologous gene has been stably integrated into genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example, antisense technology, cosuppression technology 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 compounds 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 color, 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 compound combinations according to the invention may also have a strengthening effect in plants. Accordingly, they are also suitable for mobilizing the defense system of the plant against attack by unwanted microorganisms. This may, if appropriate, be one of the reasons of 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 defense system of plants in such a way that, when subsequently inoculated with unwanted microorganisms, the treated plants display a substantial degree of resistance to these microorganisms. In the present case, unwanted microorganisms 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 compounds.
Plants and plant cultivars which are preferably to be treated according to the invention include all plants which have genetic material which impart particularly advantageous, useful traits to these plants (whether obtained by breeding and/or biotechnological means).
Plants and plant cultivars which are also preferably to be treated according to the invention are resistant against one or more biotic stresses, i.e. said plants show a better defense against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
Plants and plant cultivars which may also be treated according to the invention are those plants which are resistant to one or more abiotic stresses. Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, flooding, increased soil salinity, increased mineral exposure, ozone exposure, high light exposure, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients, shade avoidance. Plants and plant cultivars which may also be treated according to the invention, are those plants characterized by enhanced yield characteristics. Increased yield in said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can furthermore be affected by improved plant architecture (under stress and non-stress conditions), including but not limited to, early flowering, flowering control for hybrid seed production, seedling vigor, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processability and better storage stability.
Non-exhaustive examples of plants with the above-mentioned traits are disclosed in the references listed in Table A.
Plants that may be treated according to the invention are hybrid plants that already express the characteristic of heterosis or hybrid vigor which results in generally higher yield, vigor, health and resistance towards biotic and abiotic stresses). 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 corn) be produced by detasseling, i.e. the mechanical removal of the male reproductive organs (or males 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 the hybrid plants 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 92/05251, WO 95/09910, WO 98/27806, WO 05/002324, WO 06/021972 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 91/02069).
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-resistant plants are for example glyphosate-tolerant plants, i.e. plants made tolerant to the herbicide glyphosate or salts thereof. Plants can be made tolerant to glyphosate through different means. 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., 1983, Science 221, 370-371), the CP4 gene of the bacterium Agrobacterium sp. (Barry et al., 1992, Curr. Topics Plant Physiol. 7, 139-145), the genes encoding a Petunia EPSPS (Shah et al., 1986, Science 233, 478-481), a Tomato EPSPS (Gasser et al., 1988, J. Biol. Chem. 263, 4280-4289), or an Eleusine EPSPS (WO 01/66704). It can also be a mutated EPSPS as described in for example EP 0837944, WO 00/66746, WO 00/66747 or WO02/26995. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxido-reductase enzyme as described in U.S. Pat. Nos. 5,776,760 and 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 02/36782, WO 03/092360, WO 05/012515 and WO 07/024782. Glyphosate-tolerant plants can also be obtained by selecting plants containing naturally-occurring mutations of the above-mentioned genes, as described in for example WO 01/024615 or WO 03/013226.
Other herbicide resistant plants are for example plants that are made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinothricin or glufosinate. Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant glutamine synthase enzyme that is resistant to inhibition. One such efficient detoxifying enzyme is an enzyme encoding a phosphinothricin acetyltransferase (such as the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinothricin acetyltransferase are for example described in U.S. Pat. Nos. 5,561,236; 5,648,477; 5,646,024; 5,273,894; 5,637,489; 5,276,268; 5,739,082; 5,908,810 and 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 catalyze 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 96/38567, WO 99/24585 and WO 99/24586. 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 99/34008 and WO 02/36787. Tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate deshydrogenase in addition to a gene encoding an HPPD-tolerant enzyme, as described in WO 2004/024928.
Still further herbicide resistant plants are plants that are made tolerant to acetolactate synthase (ALS) inhibitors. Known ALS-inhibitors include, for example, sulfonylurea, imidazolinone, triazolopyrimidines, pryimidinyoxy(thio)benzoates, and/or sulfonylaminocarbonyltriazolinone 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 (2002, Weed Science 50:700-712), but also, in U.S. Pat. Nos. 5,605,011, 5,378,824, 5,141,870, and 5,013,659. The production of sulfonylurea-tolerant plants and imidazolinone-tolerant plants is described in U.S. Pat. Nos. 5,605,011; 5,013,659; 5,141,870; 5,767,361; 5,731,180; 5,304,732; 4,761,373; 5,331,107; 5,928,937; and 5,378,824; and international publication WO 96/33270. 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 sulfonylurea- and imidazolinone-tolerant plants are also described in for example WO 07/024782.
Other plants tolerant to imidazolinone and/or sulfonylurea can be obtained by induced mutagenesis, selection in cell cultures in the presence of the herbicide or mutation breeding as described for example for soybeans in U.S. Pat. No. 5,084,082, for rice in WO 97/41218, for sugar beet in U.S. Pat. No. 5,773,702 and WO 99/057965, for lettuce in U.S. Pat. No. 5,198,599, or for sunflower in WO 01/065922.
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:
1) an insecticidal crystal protein from Bacillus thuringiensis or an insecticidal portion thereof, such as the insecticidal crystal proteins listed by Crickmore et al. (1998, Microbiology and Molecular Biology Reviews, 62: 807-813), updated by Crickmore et al. (2005) at the Bacillus thuringiensis toxin nomenclature, online at: http://www.lifesci.sussex.ac.uk/Home/Neil_Crickmore/Bt/), or insecticidal portions thereof, e.g., proteins of the Cry protein classes Cry1Ab, Cry1Ac, Cry1B, Cry1C, Cry1D, Cry1F, Cry2Ab, Cry3Aa, or Cry3Bb or insecticidal portions thereof (e.g. EP 1999141 and WO 2007/107302); or
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 10. In one embodiment, an insect-resistant plant contains more than one transgene encoding a protein of any one of the above classes 1 to 10, to expand the range of target insect species affected when using different proteins directed at different target insect species, 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.
An “insect-resistant transgenic plant”, as used herein, further includes any plant containing at least one transgene comprising a sequence producing upon expression a double-stranded RNA which upon ingestion by a plant insect pest inhibits the growth of this insect pest, as described e.g. in WO 2007/080126.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are tolerant to abiotic stresses.

Such plants can be obtained by genetic transformation, or by selection of plants contain a mutation imparting such altered fiber characteristics and include:
a) Plants, such as cotton plants, containing an altered form of cellulose synthase genes as described in WO 98/00549
Plants or plant cultivars (that can be obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as oilseed rape or related Brassica plants, with altered oil profile characteristics. Such plants can be obtained by genetic transformation, or by selection of plants contain a mutation imparting such altered oil profile characteristics and include:

Such plants can be obtained by genetic transformation, or by selection of plants contain a mutation imparting such altered seed shattering characteristics and include plants such as oilseed rape plants with delayed or reduced seed shattering as described in U.S. Patent Appl. No. 61/135,230 and EP 08075648.9.
Particularly useful transgenic plants which may be treated according to the invention are plants containing transformation events, or combination of transformation events, that are the subject of petitions for non-regulated status, in the United States of America, to the Animal and Plant
Health Inspection Service (APHIS) of the United States Department of Agriculture (USDA) whether such petitions are granted or are still pending. At any time this information is readily available from APHIS (4700 River Road Riverdale, Md. 20737, USA), for instance on its internet site (URL http://www.aphis.usda.gov/brs/notreg.html).
Additional particularly useful plants containing single transformation events or combinations of transformation events 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).
Further particularly transgenic plants include plants containing a transgene in an agronomically neutral or beneficial position as described in any of the patent publications listed in Table C.

The damaging insects of crops which can be controlled at any development stage by using the pesticide composition according to the invention include:
Leucophaea maderae, Blattella germanica;
Haematopinus spp., Linognathus spp., Trichodectes spp., Damalinia spp.;
As a further aspect, the present invention provides a product comprising compounds (A), (B), (C) and (D) as herein defined, as a combined preparation for simultaneous, separate or sequential use in controlling the phytopathogenic fungi or damaging insects of plants, crops or seeds at a site.
The pesticide composition according to the invention can be prepared immediately before use by using a kit-of-parts for controlling, curatively or preventively, the phytopathogenic fungi of crops, such a kit-of-parts may comprise at least one or several compounds (A), (B), (C) and (D) intended to be combined or used simultaneously, separately or sequentially in controlling the phytopathogenic fungi of crops at a site.
It is therefore a pack wherein the user finds all the ingredients for preparing the fungicide formulation which they wish to apply to the crops. These ingredients, which comprise in particular the active agents (A), (B), (C) and (D) and which are packaged separately, are provided in the form of a powder or in the form of a liquid which is concentrated to a greater or lesser degree. The user simply has to mix in the prescribed doses and to add the quantities of liquid, for example of water, necessary to obtain a formulation which is ready to use and which can be applied to the crops.
The good fungicidal activity of the active compound combinations according to the invention is evident from the example below. While the individual active compounds exhibit weaknesses with regard to the fungicidal activity, the combinations have an activity which exceeds a simple addition of activities.
A synergistic effect of fungicides is always present when the fungicidal activity of the active compound combinations exceeds the total of the activities of the active compounds when applied individually.
The expected activity for a given combination of two active compounds can be calculated as follows (cf. Colby, S.R., “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations”, Weeds 15, pages 20-22, 1967):
If
then
The degree of efficacy, expressed in % is denoted. 0% means an efficacy which corresponds to that of the control while an efficacy of 100% means that no disease is observed.
If the actual fungicidal activity exceeds the calculated value, then the activity of the combination is superadditive, i.e. a synergistic effect exists. In this case, the efficacy which was actually observed must be greater than the value for the expected efficacy (E) calculated from the abovementioned formula.
The invention is illustrated by the following examples.
Solvent: 24,5 parts by weight of acetone
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.
To test for protective activity, young plants are sprayed with the preparation of active compound at the stated rate of application. After the spray coating has dried on, the plants are inoculated with an aqueous spore suspension of Phytophthora infestans. The plants are then placed in an incubation cabinet at approximately 20° C. and a relative atmospheric humidity of 100%.
The test is evaluated 3 days after the inoculation. 0% means an efficacy which corresponds to that of the control, while an efficacy of 100% means that no disease is observed.
The tables below clearly shows that the observed activity of the active compound combination according to the invention is greater than the calculated activity, i.e. a synergistic effect is present.
Solvent: 24,5 parts by weight of acetone
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier, and the concentrate is diluted with water to the desired concentration.
To test for protective activity, young plants are sprayed with the preparation of active compound at the stated rate of application. After the spray coating has dried on, the plants are inoculated with an aqueous conidia suspension of the causal agent of apple scab (Venturia inaequalis) and then remain for 1 day in an incubation cabinet at approximately 20° C. and a relative atmospheric humidity of 100%.
The plants are then placed in a greenhouse at approximately 21° C. and a relative atmospheric humidity of approximately 90%.
The test is evaluated 10 days after the inoculation. 0% means an efficacy which corresponds to that of the control, while an efficacy of 100% means that no disease is observed.
The tables below clearly shows that the observed activity of the active compound combination according to the invention is greater than the calculated activity, i.e. a synergistic effect is present.

To test for protective activity, young plants are sprayed with the preparation of active compound. After the spray coating has dried on, 2 small pieces of agar covered with growth of Botrytis cinerea are placed on each leaf. The inoculated plants are placed in a darkened chamber at 20° C. and a relative atmospheric humidity of 100%.
2 days after the inoculation, the size of the lesions on the leaves is evaluated. 0% means an efficacy which corresponds to that of the control, while an efficacy of 100% means that no disease is observed.
The table below clearly shows that the observed activity of the active compound combination according to the invention is greater than the calculated activity, i.e. a synergistic effect is present.
