In formula (III), A and R' have the meanings already mentioned in connection with the description 10 of the compounds of the formula (I) according to the invention. Some of the compounds of the formula (III) can be obtained commercially or by methods known from the literature (cf., for example, S.

Houben-Weyl, Methoden der Organischen Chemie, Vol. XI/1, Georg Thieme Verlag Stuttgart, p. 602). Some of the aldehydes (A-CHO) are commercially available (cf., 5 for example, 6-chloronicotinaldehyde, 6-fluoronicotinaldehyde, 6-bromonicotinaldehyde, 2-chloro 1,3-thiazole-5-carbaldehyde), or they can be obtained by methods known from the literature (cf., for example, 6-methylnicotinaldehyde: EP 104876 A2; 2-chloropyrazine-5-carboxaldehyde: DE 3314196 Al). In general, it is advantageous to carry out the preparation process 1 according to the invention in 10 the presence of diluents. Diluents are advantageously employed in such an amount that the reaction mixture remains readily stirrable during the entire process. Suitable diluents for carrying out the process 1 according to the invention are all organic solvents which are inert under the reaction conditions.

When used as insecticides, the active compounds according to the invention can furthermore be 10 present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergists. Synergists are compounds which increase the action of the active compounds, without it being necessary for the synergistic agent added to be active itself. When used as insecticides, the active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these 15 formulations, as a mixture with inhibitors which reduce degradation of the active compound after use in the environment of the plant, on the surface of parts of plants or in plant tissues. The active compound content of the use forms prepared from the commercially available formula tions can vary within wide limits. The active compound concentration of the use forms can be from 0.00000001 to 95% by weight of active compound, preferably between 0.0000 1 and 1% by weight. 20 The compounds are employed in a customary manner appropriate for the use forms. All plants and plant parts can be treated in accordance with the invention. Plants are to be under stood as meaning in the present context all plants and plant populations such as desired and unde sired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by bio 25 technological and genetic engineering methods or by combinations of these methods, including the transgenic'plants and including the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant 30 parts also include harvested material, and vegetative and generative propagation material, for ex ample cuttings, tubers, rhizomes, offshoots and seeds. Treatment according to the invention of the plants and plant parts with the active compounds is carried out directly or by allowing the compounds to act on the surroundings, habitat or storage space by the customary treatment methods, for example by immersion, spraying, evaporation, fog ging, scattering, painting on, injection and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats. 5 Treatment according to the invention of the plants and plant parts with the active compound corn binations is carried out directly or by allowing the compounds to act on the surroundings, habitat or storage space by the customary treatment methods, for example by immersion, spraying, evapo ration, fogging, scattering, painting on, and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats. 10 The mixtures according to the invention are particularly suitable for treating seed. Here, the com binations according to the invention mentioned above as preferred or particularly preferred may be mentioned as being preferred. Thus, a large part of the damage to crop plants which is caused by pests occurs as early as when the seed is attacked during storage and after the seed is introduced into the soil, during and immediately after germination of the plants. This phase is particularly 15 critical since the roots and shoots of the growing plant are particularly sensitive and even minor damage can lead to the death of the whole plant. Protecting the seed and the germinating plant by the use of suitable compositions is therefore of particularly great interest. The control of pests by treating the seeds of plants has been known for a long time and is the sub ject of continuous improvements. However, the treatment of seed entails a series of problems 20 which cannot always be solved in a satisfactory manner. Thus, it is desirable to develop methods for protecting the seed and the germinating plant which dispense with the additional application of crop protection agents after sowing or after the emergence of the plants. It is furthermore desirable to optimize the amount of active compound employed in such a way as to provide maximum pro tection for the seed and the germinating plant from attack by pests, but without damaging the plant 25 itself by the active compound. employed. In particular, methods for the treatment of seed should also take into consideration the intrinsic insecticidal properties of transgenic plants in order to achieve optimum protection of the seed and the germinating plant with a minimum of crop protec tion agents being employed. The present invention therefore in particular also relates to a method for the protection of seed and 30 germinating plants from attack by pests, by treating the seed with a composition according to the invention. The invention likewise relates to the use of the compositions according to the invention for the treatment of seed for protecting the seed and the resultant plant from pests. Furthermore, the invention relates to seed which has been treated with a composition according to the invention so as to afford protection from pests.

One of the advantages of the present invention is that the particular systemic properties of the compositions according to the invention mean that treatment of the seed with these compositions not only protects the seed itself, but also the resulting plants after emergence, from pests. In this manner, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dis 5 pensed with. A further advantage is the synergistically increased insecticidal activity of the compositions ac cording to the invention in comparison with the individual insecticidal active compound, which exceeds the anticipated activity of the two active compounds when applied individually. Also ad vantageous is the synergistically increased fungicidal activity of the compositions according to the 10 invention in comparison with the individual fungicidal active compound, which exceeds the antici pated activity of the active compound when applied individually. This makes possible an optimiza tion of the amount of active compound employed. Furthermore, it must be considered as advantageous that the mixtures according to the invention can also be employed in particular in transgenic seed, the plants arising from this seed being capa 15 ble of expressing a protein directed against pests. By treating such seed with the compositions according to the invention, certain pests can be controlled merely by the expression of the, for example, insecticidal protein, and additionally be protected by the compositions according to the invention against damage. The compositions according to the invention are suitable for protecting seed of any plant variety as 20 already mentioned above which is employed in agriculture, in the greenhouse, in forests or in hor ticulture. In particular, this takes the form of seed of maize, peanut, canola, oilseed rape, poppy, soya beans, cotton, beet (for example sugar beet and fodder beet), rice, sorghum and millet, wheat, barley, oats, rye, sunflower, tobacco, potatoes or vegetables (for example tomatoes, cabbage plants). The compositions according to the invention are likewise suitable for treating the seed of 25 fruit plants and vegetables as already mentioned above. The treatment of the seed of maize, soya beans, cotton, wheat and canola or oilseed rape is of particular importance. As already mentioned above, the treatment of transgenic seed with a composition according to the invention is also of particular importance. This takes the form of seed of plants which, as a rule, comprise at least one heterologous gene which governs the expression of a polypeptide with in 30 particular insecticidal properties. In this context, the heterologous genes in transgenic seed may be derived from microorganisms such as Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter, Glomus or Gliocladium. The present invention is particularly suitable for the treat ment of transgenic seed which comprises at least one heterologous gene orignating from Bacillus sp. and whose gene product shows activity against the European corn borer and/or the corn root worm. It is particularly preferably a heterologous gene derived from Bacillus thuringiensis. In the context of the present invention, the composition according to the invention is applied to the seed either alone or in a suitable formulation. Preferably, the seed is treated in a state which is 5 stable enough to avoid damage during treatment. In general, the seed may be treated at any point in time between harvest and sowing. The seed usually used has been separated from the plant and freed from cobs, shells, stalks, coats, hairs or the flesh of the fruits. When treating the seed, care must generally be taken that the amount of the composition according to the invention applied to the seed and/or the amount of further additives is chosen in such a way 10 that the germination of the seed is not adversely affected, or that the resulting plant is not dam aged. This must be borne in mind in particular in the case of active compounds which may have phytotoxic effects at certain application rates. As already mentioned above, it is possible to treat all plants and their parts according to the inven tion. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by con 15 ventional 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 ge netic 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. 20 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, cli 25 mate, vegetation period, diet), the treatment according to the invention may also result in superad ditive ("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 tempera tures, increased tolerance to drought or to water or soil salt content, increased flowering perform 30 ance, easier harvesting, accelerated maturation, higher harvest yields, higher 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 (obtained by genetic engineering) which are preferably to be treated according to the invention include all plants which, by virtue of the genetic modifica tion, received genetic material which imparted particularly advantageous, useful traits to these plants. Examples of such traits are better plant growth, increased tolerance to high or low tempera tures, increased tolerance to drought or to water or soil salt content, increased flowering perform 5 ance, easier harvesting, accelerated maturation, higher harvest yields, higher 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 traits are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopa thogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbi 10 cidally active compounds. Examples of transgenic plants which may be mentioned are the impor tant crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, sugar beet, tomatoes, peas and other vegetable varieties, cotton, tobacco, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton, tobacco and oilseed rape, Traits that are emphasized are in particular increased 15 defence of the plants against insects, arachnids, nematodes and slugs and snails by virtue of toxins forrned 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, CryIIB2, Cry9c, Cry2Ab, Cry3Bb and CrylIF and also combinations thereof) (referred to hereinbelow as "Bt plants"). Traits that are also particularly emphasized are the increased defence of the plants against 20 fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Traits that are further more particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for ex ample the "PAT" gene). The genes which impart the desired traits in question can also be present 25 in combination with one another in the transgenic plants.
