A mixture with other known active compounds such as herbicides, fertilizers, growth regulators, safeners, semiochemicals or else with agents which improve the plant characteristics, is also possible.

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 formulations as mixtures with synergists. Synergists are compounds by which the activity of the active compound is enhanced without it being necessary for the synergist 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 formulations, as mixtures with inhibitors which reduce degradation of the active compound post- application in the environment of the plant, on the surface of plant parts or in plant tissues.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.00000001 up to 95% by weight of active compound, preferably between 0.00001 and 1% by weight.

Application is effected in a customary manner which is adapted to suit the use forms.

As already mentioned above, all plants and their parts can be treated in accordance with the invention. In a preferred use form, plant species and plant varieties, and their parts, which are found in the wild or which are obtained by conventional biological breeding methods, such as hybridization or protoplast fusion, are treated. In a further preferred embodiment, transgenic plants and plant varieties, and their parts, which have been obtained by genetic engineering methods, if appropriate in combination with traditional methods (genetically modified organisms) are treated. The terms "parts", "parts of plants" or "plant parts" have been detailed above.

It is especially preferred to treat, in accordance with the invention, plants of the plant varieties which are in each case commercially available or in use. Plant cultivars are understood as meaning plants with new properties ("traits") which have been obtained by conventional cultivation, by mutagenesis or else by recombinant DNA techniques. These may be cultivars, biotypes or genotypes.

Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, nutrition), the treatment according to the invention may also result in superadditive ("synergistic") effects. Thus, for example, reduced application rates and/or widenings of the activity spectrum and/or an increase in the activity of the substances and compositions that can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance of the crop plants to drought or to water or soil salinity, increased flowering performance, easier harvesting, accelerated maturation, higher yields, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products which exceed the effects which were actually to be expected are possible.

The preferred transgenic plants or plant cultivars (i.e. those obtained by genetic engineering) which are to be treated according to the invention include all plants which, by genetic modification, received genetic material which imparted particularly advantageous useful properties ("traits") to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salinity, increased flowering performance, easier harvesting, accelerated maturation, higher 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 defense 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, sugar beet, tomatoes, peas and other vegetables, 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 in particular are increased defense of the plants against insects, arachnids, nematodes, slugs and snails as the result of toxins formed in the plants, in particular those formed in the plants by the genetic material from Bacillus thuringiensis (for example by the genes CryΙA(a), CryΙA(b), CryΙA(c), CryllA, CryllLA, CryIIEB2, Cry9c, Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as "Bt plants"). Traits which are also particularly emphasized are the increased defense

of plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and the 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, glyphosates or phosphinothricin (for example the "PAT" gene). The genes which impart the desired traits in question 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 beans), KnockOut® (for example corn), StarLink® (for example corn), Bollgard® (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 glyphosates, for example maize, cotton, soya beans), Liberty Link® (tolerance to phosphinothricin, 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 also include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant varieties having these genetic traits or genetic traits, which will be developed in the future, which varieties will be developed and/or marketed in the future.

The plants listed can be treated according to the invention in a particularly advantageous manner with the compounds of the general formula I or the active compound mixtures according to the invention. The preferred ranges stated above for the active compounds or mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the compounds or mixtures specifically mentioned in the present text.
