However, the specific mixtures of the present invention, which are based on a compound I and compound II and compound(s) III and/or compounds IV are not explicitly disclosed therein. In addition, the specific combinations of compound I and II as defined above, is also not mentioned therein.
One typical problem arising in the field of pest control lies in the need to reduce the dosage rates of the active ingredient in order to reduce or avoid unfavorable environmental or toxicological effects whilst still allowing effective pest control.
In regard to the instant invention the term pests embrace animal pests, and harmful fungi.
Another problem encountered concerns the need to have available pest control agents which are effective against a broad spectrum of pests, e.g. both animal pests and harmful fungi.
There also exists the need for pest control agents that combine knock-down activity with prolonged control, that is, fast action with long lasting action.
Another difficulty in relation to the use of pesticides is that the repeated and exclusive application of an individual pesticidal compound leads in many cases to a rapid selection of pests, that means animal pests, and harmful fungi, which have developed natural or adapted resistance against the active compound in question. Therefore there is a need for pest control agents that help prevent or overcome resistance.
Another problem underlying the present invention is the desire for compositions that improve plants, a process which is commonly and hereinafter referred to as “plant health”.
The term plant health comprises various sorts of improvements of plants that are not connected to the control of pests. For example, advantageous properties that may be mentioned are improved crop characteristics including: emergence, crop yields, protein content, oil content, starch content, more developed root system (improved root growth), improved stress tolerance (e.g. against drought, heat, salt, UV, water, cold), reduced ethylene (reduced production and/or inhibition of reception), tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf color, pigment content, photosynthetic activity, less input needed (such as fertilizers or water), less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, enhanced plant vigor, increased plant stand and early and better germination; or any other advantages familiar to a person skilled in the art.
It was therefore an object of the present invention to provide pesticidal mixtures which solve the problems of reducing the dosage rate and/or enhancing the spectrum of activity and/or combining knock-down activity with prolonged control and/or to resistance management and/or promoting the health of plants.
We have found that this object is in part or in whole achieved by the mixtures comprising the active compounds defined in the outset.
Especially, it has been found that the mixtures as defined in the outset show markedly enhanced action against pests compared to the control rates that are possible with the individual compounds and/or is suitable for improving the health of plants when applied to plants, parts of plants, seeds, or at their locus of growth.
It has been found that the action of the inventive mixtures goes far beyond the fungicidal and/or insecticidal and/or plant health improving action of the active compounds present in the mixture alone.
Moreover, we have found that simultaneous, that is joint or separate, application of the compound I and the compound II and compound(s) III and/or compound IV or successive application of the compound I and the compound II and compound(s) III and/or compound IV allows enhanced control of pests, that means animal pests, and harmful fungi, compared to the control rates that are possible with the individual compounds (synergistic mixtures).
Moreover, we have found that simultaneous, that is joint or separate, application of the compound I and the compound II or successive application of the compound I and the compound II allows enhanced control of pests, that means harmful fungi, compared to the control rates that are possible with the individual compounds (synergistic mixtures).
Moreover, we have found that simultaneous, that is joint or separate, application of the compound I and the compound II and compound(s) III and/or compound IV (or compound I and II as defined above) or successive application of the compound I and the compound II and compound(s) III and/or compound IV (or compound I and II as defined above) provides enhanced plant health effects compared to the plant health effects that are possible with the individual compounds.

Dilution with water gives a stable suspension of the active substance, whereby a composition with 20% (w/w) of active substance is obtained.
5 parts by weight of compounds of the inventive mixtures are ground finely and mixed intimately with 95 parts by weight of finely divided kaolin. This gives a dustable composition having an active substance content of 5% by weight.
0.5 parts by weight of compounds of the inventive mixtures is ground finely and associated with 99.5 parts by weight of carriers. Current methods are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted having an active substance content of 0.5% by weight.
10 parts by weight of compounds of the inventive mixtures are dissolved in 90 parts by weight of an organic solvent, e.g. xylene. This gives a composition to be applied undiluted having an active substance content of 10% by weight.
The agrochemical formulations generally comprise between 0.01 and 95%, preferably between 0.1 and 90%, most preferably between 0.5 and 90%, by weight of active substances. The compounds of the inventive mixtures are employed in a purity of from 90% to 100%, preferably from 95% to 100% (according to NMR spectrum).
The compounds of the inventive mixtures can be used as such or in the form of their compositions, e.g. in the form of directly sprayable solutions, powders, suspensions, dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading, brushing, immersing or pouring. The application forms depend entirely on the intended purposes; it is intended to ensure in each case the finest possible distribution of the compounds present in the inventive mixtures.
Aqueous application forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.
The active substance concentrations in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.001 to 1% by weight of compounds of the inventive mixtures.
The compounds of the inventive mixtures may also be used successfully in the ultra-low-volume process (ULV), it being possible to apply compositions comprising over 95% by weight of active substance, or even to apply the active substance without additives.
Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active compounds, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the compounds of the inventive mixtures in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.
Compositions of this invention may also contain fertilizers such as ammonium nitrate, urea, potash, and superphosphate, phytotoxicants and plant growth regulators and safeners. These may be used sequentially or in combination with the above-described compositions, if appropriate also added only immediately prior to use (tank mix). For example, the plant(s) may be sprayed with a composition of this invention either before or after being treated with the fertilizers.
The compounds contained in the mixtures as defined above can be applied simultaneously, that is jointly or separately, or in succession, the sequence, in the case of separate application, generally not having any effect on the result of the control measures.
According to this invention, applying the compound I and II and compound (s) III and/or IV (or compound I and II as defined above) is to be understood to denote, that at least the compound I and II and compound (s) III and/or IV (or compound I and II as defined above) occur simultaneously at the site of action (i.e. the pests, such as harmful fungi and animal pests such as insects, arachnids or nematodes to be controlled (for the binary mixtures harmful fungi) or their habitats such as infected plants, plant propagation materials, particularly seeds, surfaces, materials or the soil as well as plants, plant propagation materials, particularly seeds, soil, surfaces, materials or rooms to be protected from fungal attack) in a effective amount.
This can be obtained by applying the compound I and II and compound (s) III and/or IV (or compound I and II as defined above) simultaneously, either jointly (e.g. as tank-mix) or separately, or in succession, wherein the time interval between the individual applications is selected to ensure that the active substance applied first still occurs at the site of action in a sufficient amount at the time of application of the further active substance(s). The order of application is not essential for working of the present invention.
In binary, ternary and quaternary mixture of the present invention, the weight ratio of the compounds generally depends from the properties of the compounds of the inventive mixtures.
The compounds of the inventive mixtures can be used individually or already partially or completely mixed with one another to prepare the composition according to the invention. It is also possible for them to be packaged and used further as combination composition such as a kit of parts.
In one embodiment of the invention, the kits may include one or more, including all, components that may be used to prepare a subject agrochemical composition. E.g., kits may include the compound I and II and compound (s) III and/or IV (or compound I and II as defined above) and/or an adjuvant component and/or a further pesticidal compound (e.g. insecticide or herbicide) and/or a growth regulator component). One or more of the components may already be combined together or pre-formulated. In those embodiments where more than two components are provided in a kit, the components may already be combined together and as such are packaged in a single container such as a vial, bottle, can, pouch, bag or canister. In other embodiments, two or more components of a kit may be packaged separately, i.e., not pre-formulated. As such, kits may include one or more separate containers such as vials, cans, bottles, pouches, bags or canisters, each container containing a separate component for an agrochemical composition. In both forms, a component of the kit may be applied separately from or together with the further components or as a component of a combination composition according to the invention for preparing the composition according to the invention.
The user applies the composition according to the invention usually from a predosage device, a knapsack sprayer, a spray tank or a spray plane. Here, the agrochemical composition is made up with water and/or buffer to the desired application concentration, it being possible, if appropriate, to add further auxiliaries, and the ready-to-use spray liquor or the agrochemical composition according to the invention is thus obtained. Usually, 50 to 500 liters of the ready-to-use spray liquor are applied per hectare of agricultural useful area, preferably 100 to 400 liters.
According to one embodiment, individual compounds of the inventive mixtures formulated as composition (or formulation) such as parts of a kit or parts of a binary or ternary or quaternary mixture may be mixed by the user himself in a spray tank and further auxiliaries may be added, if appropriate (tank mix).
In a further embodiment, either individual compounds of the inventive mixtures formulated as composition or partially premixed components, e.g. components comprising the compound I and II and compound (s) III and/or IV (or compound I and II as defined above) may be mixed by the user in a spray tank and further auxiliaries and additives may be added, if appropriate (tank mix).
In a further embodiment, either individual components of the composition according to the invention or partially premixed components, e.g. components comprising the compound I and II and compound (s) III and/or IV (or compound I and II as defined above), can be applied jointly (e.g. after tank mix) or consecutively.
As said above, the present invention comprises a method for controlling pests, that means animal pests and/or harmful fungi, wherein the pest, their habitat, breeding grounds, their locus or the plants to be protected against pest attack, the soil or plant propagation material (preferably seed) are treated with an pesticidally effective amount of a mixture.
Advantageously, the inventive mixtures are suitable for controlling the following fungal plant diseases:
The inventive mixtures are also suitable for controlling harmful fungi in the protection of materials (e.g. wood, paper, paint dispersions, fiber or fabrics) and in the protection of stored products. As to the protection of wood and construction materials, the particular attention is paid to the following harmful fungi: Ascomycetes such as Ophiostoma spp., Ceratocystis spp., Aureobasidium pullulans, Sclerophoma spp., Chaetomium spp., Humicola spp., Petriella spp., Trichurus spp.; Basidiomycetes such as Coniophora spp., Coriolus spp., Gloeophyllum spp., Lentinus spp., Pleurotus spp., Poria spp., Serpula spp. and Tyromyces spp., Deuteromycetes such as Aspergillus spp., Cladosporium spp., Penicillium spp., Trichorma spp., Alternaria spp., Paecilomyces spp. and Zygomycetes such as Mucor spp., and in addition in the protection of stored products the following yeast fungi are worthy of note: Candida spp. and Saccharomyces cerevisae.
They are particularly important for controlling a multitude of fungi on various cultivated plants, such as bananas, cotton, vegetable species (for example cucumbers, beans and cucurbits), cereals such as wheat, rye, barley, rice, oats; grass coffee, potatoes, corn, fruit species, soya, tomatoes, grapevines, ornamental plants, sugar cane and also on a large number of seeds.

The mixtures according to the invention can be applied to any and all developmental stages of pests, such as egg, larva, pupa, and adult. The pests may be controlled by contacting the target pest, its food supply, habitat, breeding ground or its locus with a pesticidally effective amount of the inventive mixtures or of compositions comprising the mixtures.
“Locus” means a plant, plant propagation material (preferably seed), soil, area, material or environment in which a pest is growing or may grow.
In general, “pesticidally effective amount” means the amount of the inventive mixtures or of compositions comprising the mixtures needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various mixtures/compositions used in the invention. A pesticidally effective amount of the mixtures/compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.
As said above, the present invention comprises a method for improving the health of plants, wherein the plant, the locus where the plant is growing or is expected to grow or plant propagation material, from which the plant grows, is treated with an plant health effective amount of an inventive mixture.
The term “plant effective amount” denotes an amount of the inventive mixtures, which is sufficient for achieving plant health effects as defined hereinbelow. More exemplary information about amounts, ways of application and suitable ratios to be used is given below. Anyway, the skilled artisan is well aware of the fact that such an amount can vary in a broad range and is dependent on various factors, e.g. the treated cultivated plant or material and the climatic conditions.
When preparing the mixtures, it is preferred to employ the pure active compounds, to which further active compounds against pests, such as insecticides, herbicides, fungicides or else herbicidal or growth-regulating active compounds or fertilizers can be added as further active components according to need.
The inventive mixtures are employed by treating the fungi or the plants, plant propagation materials (preferably seeds), materials or soil to be protected from fungal attack with a pesticidally effective amount of the active compounds. The application can be carried out both before and after the infection of the materials, plants or plant propagation materials (preferably seeds) by the pests.
In the method of combating harmful fungi depending on the type of compound and the desired effect, the application rates of the mixtures according to the invention are from 0.3 g/ha to 2000 g/ha, preferably 5 g/ha to 2000 g/ha, more preferably from 50 to 900 g/ha, in particular from 50 to 750 g/ha.
In the method of combating animal pests (insects, acarids or nematodes) depending on the type of compound and the desired effect, the application rates of the mixtures according to the invention are from 0.3 g/ha to 2000 g/ha, preferably 5 g/ha to 2000 g/ha, more preferably from 50 to 900 g/ha, in particular from 50 to 750 g/ha.
The inventive mixtures or compositions of these mixtures can also be employed for protecting plants from attack or infestation by animal pests (insects, acarids or nematodes) comprising contacting a plant, or soil or water in which the plant is growing.
In the context of the present invention, the term plant refers to an entire plant, a part of the plant or the propagation material of the plant.
Plants and as well as the propagation material of said plants, which can be treated with the inventive mixtures include all genetically modified plants or transgenic plants, e.g. crops which tolerate the action of herbicides or fungicides or insecticides owing to breeding, including genetic engineering methods, or plants which have modified characteristics in comparison with existing plants, which can be generated for example by traditional breeding methods and/or the generation of mutants, or by recombinant procedures.
For example, mixtures according to the present invention can be applied (as seed treatment, spray treatment, in furrow or by any other means) also to plants which have been modified by breeding, mutagenesis or genetic engineering including but not limiting to agricultural biotech products on the market or in development (cf. http://www.bio.org/speeches/pubs/er/agri_products.asp). Genetically modified plants are plants, which genetic material has been so modified by the use of recombinant DNA techniques that under natural circumstances cannot readily be obtained by cross breeding, mutations or natural recombination. Typically, one or more genes have been integrated into the genetic material of a genetically modified plant in order to improve certain properties of the plant. Such genetic modifications also include but are not limited to targeted post-transitional modification of protein(s), oligo- or polypeptides e.g. by glycosylation or polymer additions such as prenylated, acetylated or farnesylated moieties or PEG moieties.
In a preferred embodiment of the invention, the inventive mixtures are used for the protection of the seed and the seedlings' roots and shoots, preferably the seeds.
Seed treatment can be made into the seed box before planting into the field.
For seed treatment purposes, the weight ration in the binary, ternary and quaternary mixtures of the present invention generally depends from the properties of the compounds of the inventive mixtures.
Compositions, which are especially useful for seed treatment are e.g.:
A Soluble concentrates (SL, LS)
F Water-dispersible granules and water-soluble granules (WG, SG)
G Water-dispersible powders and water-soluble powders (WP, SP, WS)
I Dustable powders (DP, DS)
These compositions can be applied to plant propagation materials, particularly seeds, diluted or undiluted. The compositions in question give, after two-to-tenfold dilution, active substance concentrations of from 0.01 to 60% by weight, preferably from 0.1 to 40% by weight, in the ready-to-use preparations. Application can be carried out before or during sowing. Methods for applying or treating agrochemical compounds and compositions thereof, respectively, on to plant propagation material, especially seeds, are known in the art, and include dressing, coating, pelleting, dusting and soaking application methods of the propagation material (and also in furrow treatment). In a preferred embodiment, the compounds or the compositions thereof, respectively, are applied on to the plant propagation material by a method such that germination is not induced, e.g. by seed dressing, pelleting, coating and dusting.
In the treatment of plant propagation material (preferably seed), the application rates of the inventive mixture are generally for the formulated product (which usually comprises from 10 to 750 g/l of the active(s)).
The invention also relates to the propagation products of plants, and especially the seed comprising, that is, coated with and/or containing, a mixture as defined above or a composition containing the mixture of two or more active ingredients or a mixture of two or more compositions each providing one of the active ingredients. The plant propagation material (preferably seed) comprises the inventive mixtures in an amount of from 0.01 g to 10 kg per 100 kg of plant propagation material (preferably seed).
For example, the ratio by weight of compound I is herein preferably between 0.1-200 g/100 kg plant propagation material (preferably seed), more preferred 1 to 200 g/100 kg plant propagation material (preferably seed) and most preferred 1 to 100 g/100 kg plant propagation material (preferably seed).
For example, the ratio by weight for compound II is herein preferably between 1-200 g/100 kg plant propagation material (preferably seed), more preferred 5 to 200 g/100 kg plant propagation material (preferably seed), and most preferred 5 to 100 g/100 kg plant propagation material (preferably seed).
For example, the ratio by weight for thiophanate-methyl as compound III is herein preferably between 10-200 g/100 kg plant propagation material (preferably seed), more preferred 25 to 200 g/100 kg plant propagation material (preferably seed) and most preferred 25 to 100 g/100 kg plant propagation material (preferably seed).
For example, the ratio by weight for procloraz as compound III is herein preferably between 1-200 g/100 kg plant propagation material (preferably seed), more preferred 5 to 50 g/100 kg plant propagation material (preferably seed) and most preferred 5 to 20 g/100 kg plant propagation material (preferably seed).
For example, the ratio by weight for the strobilurins as compound III, which are azoxystrobin, pyraclostrobin, trifloxystrobin or orysastrobin (in particular orysastrobin) as compound III is herein preferably between 1-200 g/100 kg plant propagation material (preferably seed), more preferred 1 to 50 g/100 kg plant propagation material (preferably seed) and most preferred 1 to 20 g/100 kg plant propagation material (preferably seed).
For example, the ratio by weight for compound IV is herein preferably between 0, 1-200 g/100 kg plant propagation material (preferably seed), more preferred 1 to 200 g/100 kg plant propagation material (preferably seed) and most preferred 1 to 50 g/100 kg plant propagation material (preferably seed).
The separate or joint application of the compounds of the inventive mixtures is carried out by spraying or dusting the seeds, the seedlings, the plants or the soils before or after sowing of the plants or before or after emergence of the plants.
The inventive mixtures are effective through both contact (via soil, glass, wall, bed net, carpet, plant parts or animal parts), and ingestion (bait, or plant part) and through trophallaxis and transfer.
Preferred application methods are into water bodies, via soil, cracks and crevices, pastures, manure piles, sewers, into water, on floor, wall, or by perimeter spray application and bait.
According to another preferred embodiment of the invention, for use against non crop pests such as ants, termites, wasps, flies, mosquitoes, crickets, locusts, or cockroaches the inventive mixtures are prepared into a bait preparation.
The bait can be a liquid, a solid or a semisolid preparation (e.g. a gel). The bait employed in the composition is a product which is sufficiently attractive to incite insects such as ants, termites, wasps, flies, mosquitoes, crickets etc. or cockroaches to eat it. This attractant may be chosen from feeding stimulants or para and/or sex pheromones readily known in the art.
Methods to control infectious diseases transmitted by insects (e.g. malaria, dengue and yellow fever, lymphatic filariasis, and leishmaniasis) with the inventive mixtures and their respective compositions also comprise treating surfaces of huts and houses, air spraying and impregnation of curtains, tents, clothing items, bed nets, tsetse-fly trap or the like. Insecticidal compositions for application to fibers, fabric, knitgoods, non-wovens, netting material or foils and tarpaulins preferably comprise a composition including the inventive mixtures, optionally a repellent and at least one binder.
The inventive mixtures and the compositions comprising them can be used for protecting wooden materials such as trees, board fences, sleepers, etc. and buildings such as houses, outhouses, factories, but also construction materials, furniture, leathers, fibers, vinyl articles, electric wires and cables etc. from ants and/or termites, and for controlling ants and termites from doing harm to crops or human being (e.g. when the pests invade into houses and public facilities).
In the case of soil treatment or of application to the pests dwelling place or nest, the quantity of active ingredient ranges from 0.0001 to 500 g per 100 m2, preferably from 0.001 to 20 g per 100 m2.
Customary application rates in the protection of materials are, for example, from 0.01 g to 1000 g of active compound per m2 treated material, desirably from 0.1 g to 50 g per m2.
Insecticidal compositions for use in the impregnation of materials typically contain from 0.001 to 95 weight %, preferably from 0.1 to 45 weight %, and more preferably from 1 to 25 weight % of at least one repellent and/or insecticide.
For use in bait compositions, the typical content of active ingredient is from 0.0001 weight % to 15 weight %, desirably from 0.001 weight % to 5% weight % of active compound. The composition used may also comprise other additives such as a solvent of the active material, a flavoring agent, a preserving agent, a dye or a bitter agent. Its attractiveness may also be enhanced by a special color, shape or texture.
For use in spray compositions, the content of the mixture of the active ingredients is from 0.001 to 80 weights %, preferably from 0.01 to 50 weight % and most preferably from 0.01 to 15 weight %.
