They are used in the usual way, e.g. by pouring, spraying, spraying, sprinkling.
- the active compounds according to the invention can be applied both before and after emergence of the plants. They can also be worked into the soil before sowing.

- plants and their parts can be treated according to the invention.
- transgenic plants and plant cultivars which have been obtained by genetic engineering methods, if appropriate in combination with conventional methods (genetically modified organisms) and their parts are treated.
- the term "parts” or “parts of plants” or “plant parts” was explained above. Plants of the plant varieties which are in each case commercially available or in use are particularly preferably treated according to the invention. Plant cultivars are understood to mean plants with certain properties (“traits”) which have been obtained both by conventional breeding, by mutagenesis or by recombinant DNA techniques. These can be varieties, bio and genotypes.
- the treatment according to the invention can also cause superadditive (“synergistic") effects.
- superadditive for example, reduced application rates and / or widening of the activity spectrum and / or an enhancement of the action of the substances and agents which can be used according to the invention - also in combination with other agrochemical active substances - better plant growth of the crop plants, increased tolerance of the crop plants to high or low temperatures Tolerance of crops against dryness or against water or soil salt content, increased flowering performance, easier harvesting, acceleration of ripeness, higher crop yields, higher quality and / or higher nutritional value of the harvested products, higher storability and / or workability of the harvested products, which is beyond the actual expected effects go beyond.
- the preferred transgenic (genetically engineered) plants or plant cultivars to be treated according to the invention include all plants which have received genetic material through the genetic engineering modification, which gives these plants particularly advantageous, valuable properties (“traits”). Examples of such properties 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 ripening, higher harvest yields, higher quality and / or higher nutritional value of the harvested products , higher shelf life and / or workability of the harvested products.
- transgenic plants are the important crop plants, such as cereals (wheat, rice), corn, soybeans, potatoes, cotton, rapeseed and fruit plants (with the fruits apples, pears, citrus fruits and grapes), with corn, soybeans, potatoes and cotton and rapeseed are highlighted.
- the traits are particularly emphasized as the increased defense of the plants against insects by toxins which arise in the plants, in particular those which are caused by the genetic material from Bacillus thuringiensis (for example by the genes Cry ⁇ A (a), Cry ⁇ A (b), CryIA (c), CryllA, CrylllA, CryIIIB2, Cry9c, Cry2Ab, Cry3Bb and CrylF as well as their combinations) are produced in the plants (hereinafter "Bt plants”).
- the properties (“traits”) also particularly emphasize the increased defense of plants against fungi, bacteria and viruses by systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins.
- SAR systemic acquired resistance
- the properties (“traits”) which are particularly emphasized are the increased tolerance of the plants to certain herbicidal active compounds, for example imidazolinones, sulfonylureas, glyphosate or phosphinotricin (for example “PAT” gene).
- the genes imparting the desired properties (“traits”) can also occur in combinations with one another in the transgenic plants.
- Examples of "Bt plants” are corn varieties, cotton varieties, soy varieties and potato varieties that are sold under the trade names YIELD GARD® (e.g. corn, cotton, soy), KnockOut® (e.g. corn), StarLink® (e.g. corn), Bollgard® ( Cotton), Nucotn® (cotton) and NewLeaf® (potato).
- Examples of plants that are tolerant of flerbicide are maize, cotton and soybeans, which, under the Flandel names Roundup Ready® (tolerance against glyphosate e.g. corn, cotton, soy), Liberty Link® (tolerance against phosphinotricin, e.g. rapeseed), IMI® (tolerance against Imidazolinone) and STS® (tolerance to Sullbnvlharnstoi ⁇ e eg maize) are sold.
- As a flerbicide resistant (conventionally grown to herbicide tolerance) plants should also be mentioned the varieties sold under the name Clearfield® (eg maize).
- Clearfield® eg maize
