The present invention relates to novel oil-based suspension concentrates of cyclic ketoenols of the formula (I), to a process for preparing these formulations and to their use for applying the cyclic ketoenols of the formula (I) comprised therein to plants and/or their habitat and for controlling insects.
It is already known that certain cyclic ketoenols have insecticidal and/or acaricidal properties (see, for example, WO 98/05638 and WO 04/007448). Numerous water-free suspension concentrates of agrochemically active compounds are likewise already known. Thus, EP-A 0 789 999 describes formulations of this type which, in addition to active compound and oil, comprise a mixture of various surfactants—including surfactants serving as penetrants—and also a hydrophobized sheet alumosilicate as thickener. The stability of these preparations is good. However, they have the disadvantage that a thickener is imperatively present, and this renders the preparation more complicated. Moreover, the thickener absorbs in each case part of the added amount of penetrant, which is then not available for its intended purpose.
WO 03/000053 describes formulations of this type which, in addition to active compound and oil, comprise a mixture of various surfactants—including surfactants serving as penetrants. The formulations described do not require a thickener for stabilization. In this publication, the synergistic effect of vegetable oils and penetrants is emphasized. These formulations have the advantage that their preparation is less complicated than the preparation of corresponding formulations comprising thickeners. However, cyclic ketoenols of the formula (I) are not mentioned.
WO 05/084441 describes formulations of this type which, in addition to certain cyclic ketoenols and oil, comprise a penetrant. Here, alkanolethoxylates are mentioned as particularly preferred penetrants. However, these formulations do not comprise a thickener.
The oil-based suspension concentrates of cyclic ketoenols described in WO 05/084441 have the disadvantage that these formulations have a very high viscosity, in particular at temperatures below 10° C. The advantage of the high viscosity of the oil-based suspension concentrates is the fact that owing to the high viscosity it is possible to avoid a sedimentation of the suspension particles in the concentrate. However, as a result of the large increase at low temperatures, the products, when used under such conditions, do not flow freely from the package. Furthermore, it is problematic to prepare the spray liquor using highly viscous formulations.
Accordingly, it is the object of the present invention to provide stable, storable oil-based suspension concentrates without the addition of thickeners, which concentrates, in general and in particular at temperatures below 10° C., have low viscosity and are thus easy to apply by the user.
This invention now provides novel oil-based suspension concentrates, comprising
R8—O—(—PO-)q-(-EO—)p—R9 (II)
Furthermore, it has been found that the oil-based suspension concentrates according to the invention can be prepared by mixing the ingredients stated above with one another and then optionally grinding the resulting suspension.
Finally, it has been found that the oil-based suspension concentrates according to the invention are highly suitable for applying the compounds of the formula (I) comprised therein to plants and/or their habitat.
Furthermore, it has been found that the oil-based suspension concentrates according to the invention are highly suitable for controlling insects.
It is extremely surprising that the oil-based suspension concentrates according to the invention have a considerably lower viscosity, in particular at temperatures below 10° C., compared to the prior-art formulations of the most similar composition. Based on the prior art described above, this effect was unforeseeable. Furthermore, it is very surprising that the biological activity of the oil-based suspension concentrates according to the invention is better than that of the prior-art formulations of the most similar composition. Finally, it is also surprising that the compatibility of the formulations with plants has been improved, although the uptake of the active compounds into the plant has been increased.
Preferred, particularly preferred, very particularly preferred, especially preferred and emphasized substituent definitions for compounds of the formula (I) are illustrated below:
in particular (a), (b), (c) or (g)
Special preference is given to suspension concentrates comprising compounds of the formula (I) from the following patents/patent applications cited on page 1 in which the radicals A, B, D, G, W, X, Y, Z, R1, R2, R6 and R7 have the meaning mentioned in the very particularly preferred ranges: WO 98/05638, WO 04/007448.
From these applications, emphasis is given to using the following compounds of the formula (I)
for suspension concentrates according to the invention.
Suitable penetrants in the present context are certain substances which are customarily used to improve penetration of agrochemically active compounds into plants. In the present context, penetrants are defined in that they penetrate from the aqueous spray liquor and/or from the spray coating into the cuticle of the plant, thus being able to increase the mobility of active compounds in the cuticle. The method described below and in the literature (Baur et al., 1997, Pesticide Science 51, 131-152) can be used to assess this property.

The content of the individual components in the oil-based suspension concentrates according to the invention may be varied within a relatively wide range. Thus, the concentrations
The oil-based suspension concentrates according to the invention are prepared by mixing the components in the respective desired ratios with one another. The components can be mixed with one another in any order. Expediently, the solid components are employed in a finely grounded state. However, it is also possible to subject the suspension formed on mixing the components initially to coarse grinding and then to fine grinding, so that the mean particle size is below 20 μm. Preference is given to suspension concentrates in which the solid particles have a mean particle size between 1 and 10 μm.
When carrying out the process according to the invention, the temperatures can be varied within a certain range. In general, the process is carried out at temperatures of from 10° C. to 60° C., preferably from 15° C. to 40° C. To carry out the process according to the invention, customary mixers and grinders used for preparing agrochemical formulations are employed.
The oil-based suspension concentrates according to the invention are formulations which remain stable even after prolonged storage at elevated temperatures or in the cold, since no crystal growth is observed. By dilution with water, they can be converted into homogeneous spray liquors. These spray liquors are applied by customary methods, i.e. for example by spraying, by watering or by injection.
The application rate of the oil-based suspension concentrates according to the invention can be varied within a relatively wide range. It depends on the respective agrochemically active compounds and their content in the compositions.
The compositions according to the invention, in combination with good plant tolerance and favourable toxicity to warm-blooded animals and being tolerated well by the environment, are suitable for protecting plants and plant organs, for increasing the harvest yields, for improving the quality of the harvested material and for controlling animal pests, in particular insects, arachnids, helminths, nematodes and molluscs, which are encountered in agriculture, in horticulture, in animal husbandry, in forests, in gardens and leisure facilities, in the protection of stored products and of materials, and in the hygiene sector.

acetylcholinesterase (AChE) inhibitors II-1
Preferably, the suspension concentrate according to the invention comprising an active compound of the formula (I-2) is mixed with at least one insecticide selected from the above list.
Very particularly preferably, the suspension concentrate comprising an active compound of the formula (I-2) is mixed with insecticides from the group of the neonicotinyls selected from the group consisting of imidacloprid (cf. EP-A-192 060), thiacloprid (cf. EP-A-235 725), acetamiprid (WO 91/04965), nitenpyram (cf. EP-A-302 389), thiamethoxam (cf. EP-A-580 533), clothianidin (cf. EP-A-376 279) and dinotefuran (cf. EP-A-649845).
Furthermore very particularly preferably, the suspension concentrate comprising an active compound of the formula (I-2) is mixed with insecticides from the group of the pyrethroids.
Furthermore very particularly preferably, the suspension concentrate comprising an active compound of the formula (I-2) is mixed with the insecticide flubendiamide (II-28-1).
These active compounds are known, for example, from The Pesticide Manual 13th edition.
With the aid of the oil-based suspension concentrates according to the invention, it is possible to apply agrochemically active compounds in a particularly advantageous manner to plants and/or their habitat. Here, the agrochemically active compounds comprised in the concentrates unfold better biological activity (in particular better insecticidal activity and/or better compatibility with crop plants) than in the case of application in the faun of the corresponding conventional formulations.
According to the invention, it is possible to treat all plants and parts of plants. Plants are to be understood here as meaning 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 breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant cultivars which can or cannot be protected by plant breeders' certificates. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes. Parts of plants also include harvested plants and vegetative and generative propagation material, for example seedlings, tubers, rhizomes, cuttings and seeds.
The treatment according to the invention of the plants and parts of plants with the suspension concentrates is carried out directly or by action on their environment, habitat or storage area according to customary treatment methods, for example by dipping, spraying, evaporating, atomizing, brushing-on and, in the case of propagation material, in particular in the case of seeds, furthermore by one- or multi-layer coating.
As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The terms “parts”, “parts of plants” and “plant parts” have been explained above.
Particularly preferably, plants of the plant cultivars which are in each case commercially available or in use are treated according to the invention. Plant cultivars are to be understood as meaning plants having novel properties (“traits”) which have been obtained by conventional breeding, by mutagenesis or by recombinant DNA techniques. These can be cultivars, bio- or genotypes.
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 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, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.
The transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are preferred and to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparts particularly advantageous useful traits to these plants. Examples of such traits are 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, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, oilseed rape, beetroot, sugar cane and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton and oilseed rape. Traits that are particularly emphasized are the increased defence of the plants against insects by toxins foamed in the plants, in particular those formed in the plants by the genetic material from Bacillus Thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are also particularly emphasized are the increased defence of plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and also resistance genes and correspondingly expressed proteins and toxins. Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes in question which impart the desired traits can also be present in combination with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya bean), KnockOut® (for example maize), StarLink® (for example maize), Boilgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas, 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). Of course, these statements also apply to plant cultivars having these or still-to-be-developed genetic traits, which plants will be developed and/or marketed in the future.
The plants listed can be treated in a particularly advantageous manner with the suspension concentrates according to the invention. The preferred ranges stated above for the suspension concentrates also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the suspension concentrates specifically mentioned in the present text.
It has furthermore been found that the compositions according to the invention have a strong insecticidal action against insects which destroy industrial materials.
The following insects may be mentioned as examples and as preferred—but without any limitation:

Bristletails, such as Lepisma saccharina.
Industrial materials in the present connection are to be understood as meaning non-living materials, such as, preferably, plastics, adhesives, sizes, papers and cardboards, leather, wood and processed wood products and coating compositions.
The ready-to-use compositions may, if appropriate, comprise further insecticides and, if appropriate, one or more fungicides.
With respect to possible additional additives, reference may be made to the insecticides and fungicides mentioned above.
The invention is illustrated by the examples below, without being limited thereby.

After the addition has ended, stirring at room temperature is continued for 10 minutes. The homogeneous suspension formed in this manner is subjected initially to coarse grinding and then to fine grinding, giving a suspension in which 90% of the solids particles have a particle size of less than 6 μm.
In the examples, the following products are used:
The complex viscosity of the suspension concentrate is determined using a Bohlin Gemini HR nano viscosimeter from Malvern Instruments, measurement parameters: frequency 0.5 Hz and a desired deformation of 0.002. The temperature is initially, over a period of 200 s, equilibrated to 20° C. and then cooled using a gradient of 1° C./minute.
To prepare a suitable solution of the preparation, 1 part by weight of the formulated substance is diluted with water to the desired concentration.
Pear trees which are heavily infested by Psylla pyri are treated with the solution of the preparation of the desired concentration. Here, heavily infested means that 40 insects per shoot (per branch) are present.
After the desired period of time, the kill in % is determined. Here, 100% means that all Psylla pyri have been killed; 0% means that none of the insects have been killed.
In this test, for example, the following formulations according to the invention show superior efficacy compared to the formulations known from the prior art:
