Patent Application
20110105321
The present invention relates to mixtures of active ingredients having synergistically enhanced action and to methods comprising applying said mixtures.
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.
Another problem encountered concerns the need to have available pest control agents which are effective against a broad spectrum of pests.
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”. For example, advantageous properties that may be mentioned are improved crop characteristics including: emergence, crop yields, protein content, more developed root system, tillering increase, increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf color, pigment content, photosynthetic activity, less fertilizers needed, 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 germination; or any other advantages familiar to a person skilled in the art. Methods for improving the health of plants by applying active compounds to the plants or the locus are a general need.
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 which have developed natural or adapted resistance against the active compound in question.
It is also an object of the present invention, with a view to reducing the application rates and broadening the activity spectrum of the active compounds I and II, to provide mixtures which, at a reduced total amount of active compounds applied, have improved activity against harmful fungi and animal pests.
It was therefore an object of the present invention to provide pesticidal mixtures which solve the problems outlined above.
The combating of harmful phytopathogenic fungi is in many regions not the only problem the farmer has to face. Also harmful insects can cause a great damage to crops and other plants. An efficient combination of fungicidal and insecticidal activity is desirable to overcome this problem. Thus, it is a further object of the present invention to provide a mixture which, on the one hand, has good fungicidal activity, and, on the other hand, good insecticidal activity, resulting in a broader pesticidal spectrum of action.
We have found that this object is in part or in whole achieved by the combination of active compounds defined as in the following.
The present invention relates to pesticidal mixtures comprising, as active compounds,
The active compounds I of the formula I, their preparation and their action against insect and acarid pests have been described in WO 2006/060029 and in WO 2007/095229. Preparation methods of active compounds I of formula I can be found therein.
The active compounds II mentioned above of groups II.A to II.F, their preparation and their action against harmful fungi are generally known (cf., for example, http://www.hclrss.demon.co.uk/index.html); they are commercially available.
We have accordingly found that several objects can be achieved by the mixtures, defined at the outset, of the active compounds I and II. Moreover, we have found that simultaneous, that is joint or separate, application of at least one compound I and at least one of the active compounds II or successive application of at least one of the compound(s) I and at least one of the active compounds II allows better control of harmful fungi than is possible with the individual compounds alone (synergistic mixtures).
Moreover, the present invention relates to:
The compounds I can be used as synergists for a large number of different fungicidal active compounds. By simultaneous, that is joint or separate, application of compound(s) I with at least one active compound II, the fungicidal and/or insecticidal activity is increased in a superadditive manner.
The compounds I can be present in different crystal modifications, which may differ in biological activity.

Powders, materials for spreading and dustable products can be prepared by mixing or concomitantly grinding the active substances with a solid carrier.
Granules, for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers.
Examples of solid carriers are mineral earths such as silica gels, silicates, talc, kaolin, attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as, for example, ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders and other solid carriers.
In general, the formulations comprise from 0.01 to 95% by weight, preferably from 0.1 to 90% by weight, of the active compounds. In this case, the active compounds are employed in a purity of from 90% to 100% by weight, preferably 95% to 100% by weight (according to NMR spectrum or HLPC spectrum).
For seed treatment purposes, respective formulations can be diluted 2-10 fold leading to concentrations in the ready to use preparations of 0.01 to 60% by weight active compounds by weight, preferably 0.1 to 40% by weight.
The mixtures of the present invention can be used as such, in the form of their formulations or the use forms prepared therefrom, for example in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; they are intended to ensure in each case the finest possible distribution of the active compounds according to the invention.
Aqueous use 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. However, it is also 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 compound 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 0.01 to 1% per weight.
The active compound(s) may also be used successfully in the ultra-low-volume process (ULV), it being possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.

For example, the plant(s) may be sprayed with a composition of this invention either before or after being treated with other active ingredients.
The one or more active compound(s) I and the one or more active compound(s) II can be applied according to different ways of applications, which are
Therefore, the method for controlling harmful fungi and animal pests is carried out by the separate or joint application of at least one active compound I and at least one of the active compound II, or a mixture of at least one active compounds I and at least one of the active compound II, by spraying or dusting the seeds, the plants or the soils before or after sowing of the plants or before or after emergence of the plants.
The inventive mixtures or compositions of these mixtures can also be employed for protecting plants from attack or infestation by 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, that is, the seed or the seedling.
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.
Some of the inventive mixtures have systemic action and can therefore be used for the protection of the plant shoot against foliar pests as well as for the treatment of the seed and roots against soil pests.
The mixtures of compounds I and II or their corresponding formulations are applied by treating the harmful fungi and the animal pests, their habitat or the plants, seeds, soils, areas, materials or spaces to be kept free from them with a pesticidally effective amount of the mixture or, in the case of separate application, of the compounds I and II. Application can be before or after the infection by harmful fungi and/or animal pests.
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.
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.

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 %.
In general, “synergistically effective amount” means that the one or more active compound(s) I and the one or more active compound(s) II are usually applied in a weight ratio of from 500:1 to 1:100, preferably from 20:1 to 1:50, in particular from 5:1 to 1:20. Depending on the nature of the compounds the employed weight ratio of compound(s) I and compound(s) II ranges can start from 100:1 to 1:100, preferably from 20:1 to 1:20, in particular from 10:1 to 1:10.
Further active compounds are, if desired, mixed in a ratio of from 20:1 to 1:20 to the compound I.
Depending on the desired effect, the application rates of the mixtures according to the invention are from 5 g/ha to 2000 g/ha, preferably from 20 to 1500 g/ha, more preferably from 50 to 1000 g/ha and in particular from 50 to 750 g/ha. For use in treating crop plants, the rate of application of the mixture of the active ingredients of this invention may be in the range of 0.1 g to 4000 g per hectare, desirably from 25 g to 600 g per hectare, more desirably from 50 g to 500 g per hectare.
Correspondingly, the application rates for the compound(s) I are generally from 1 to 1000 g/ha, preferably from 10 to 900 g/ha, in particular from 20 to 750 g/ha.
Correspondingly, the application rates for the active compound II are generally from 1 to 2000 g/ha, preferably from 10 to 1500 g/ha, in particular from 40 to 1000 g/ha.

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 mixtures according to the invention can be applied to any and all developmental stages, 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” in general means a plant, seed, soil, area, material or environment in which pests or fungi are growing or may grow.
The mixtures according to the invention are effective through both contact and ingestion.
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.
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.
For use in bait compositions, the typical content of active ingredient(s) 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.
According to a preferred embodiment of the invention, the mixtures according to the present invention are employed via soil application. Soil application is especially favorable for use against ants, termites, crickets, or cockroaches.

For example, the active mixtures can be employed in treatment of seeds from plants, which are resistant to herbicides from the group consisting of the sulfonylureas, imidazolinones, glufosinate-ammonium or glyphosate-isopropylammonium and analogous active substances (see for example, EP-A-0242236, EP-A-242246) (WO 92/00377) (EP-A-0257993, U.S. Pat. No. 5,013,659) or in transgenic crop plants, for example cotton, with the capability of producing Bacillus thuringiensis toxins (Bt toxins) which make the plants resistant to certain pests (EP-A-0142924, EP-A-0193259),
Furthermore, the mixtures according to the present invention can be used also for the treatment of seeds from plants, which have modified characteristics in comparison with existing plants consist, which can be generated for example by traditional breeding methods and/or the generation of mutants, or by recombinant procedures).

The fungicidal effect of the compound and the mixtures can be demonstrated by the following tests:
The active compounds, separately or jointly, are prepared as a stock solution comprising 0.25% by weight of active compounds in acetone or DMSO. 1% by weight of the emulsifier Uniperol® EL (wetting agent having emulsifying and dispersant action based on ethoxylated alkylphenols) is added to this solution, and the mixture is diluted with water to the desired concentration.
The visually determined percentages of infected leaf areas are converted into efficacies in % of the untreated control:
The efficacy (E) is calculated as follows using Abbot's formula:
E=(1−α/β)·100
An efficacy of 0 means that the infection level of the treated plants corresponds to that of the untreated control plants; an efficacy of 100 means that the treated plants are not infected.
The expected efficacies of mixtures of active compounds is determined using Colby's formula (Colby, S. R. “Calculating synergistic and antagonistic responses of herbicide Combinations”, Weeds, 15, 20-22, 1967) and compared with the observed efficacies.
Colby's formula:
E=x+y−x·y/100
Leaves of pot-grown rice seedlings are sprayed to run-off with an aqueous suspension containing a certain concentration of active ingredients prepared from a stock solution. The plants are allowed to air-dry. At the following day the plants are inoculated with an aqueous spore suspension of Cochliobolus miyabeanus. Then the trial plants are immediately transferred to a humid chamber. After 6 days at 22-24° C. and a relative humidity close to 100% the extent of fungal attack on the leaves is visually assessed as % diseased leaf area.
The following tests can demonstrate the control efficacy of compounds, mixtures or compositions of this invention on specific pests. However, the pest control protection afforded by the mixtures is not limited to these species. In certain instances, combinations of a compound of this invention with other invertebrate pest control compounds or agents are found to exhibit synergistic effects against certain important invertebrate pests.
The analysis of synergism of the mixtures is determined using Colby's equation.
