Embodiment 1

[0367] Example 1: Foliar Application to Spodoptera frugiperda / Cotton

[0368] Spodoptera frugiperda-resistant transgenic cotton was treated with Spodoptera frugiperda-resistant products, respectively.

[0369] Mortality was determined in % after a defined period of time. 100% means that all caterpillars have been killed; 0% means that no caterpillars have been killed.

[0370] According to the application in this test, the following complexes showed a synergistic effect compared to the individual compounds:

[0371] Table 1: Spodoptera frugiperda - test (foliar application)

[0372]

[0373] * obs. is the observed insecticidal rate

[0374] ** cal. is the insecticidal rate calculated by Colby's formula

Embodiment 2

[0375] Example 2: Foliar application of beet armyworm / corn

[0376] Transgenic maize resistant to Lepidoptera, Coleoptera and / or herbicides were treated with products resistant to beet armyworm (Spodoptera exigua), respectively.

[0377] Mortality was determined in % after a defined period of time. 100% means that all caterpillars have been killed; 0% means that no caterpillars have been killed.

[0378] According to the application in this test, the following complexes showed a synergistic effect compared to the individual compounds:

[0379] Table 2: Beet armyworm - test (foliar application)

[0380]

[0381] * obs. is the observed insecticidal rate

[0382] ** cal. is the insecticidal rate calculated by Colby's formula

Embodiment 3

[0383] Example 3: Foliar Application of Spodoptera frugiperda / Maize

[0384] Transgenic maize resistant to Lepidoptera, Coleoptera and / or herbicides were treated with products resistant to Spodoptera frugiperda, respectively.

[0385] Mortality was determined in % after a defined period of time. 100% means that all caterpillars have been killed; 0% means that no caterpillars have been killed.

[0386] According to the application in this test, the following complexes showed a synergistic effect compared to the individual compounds:

[0387] Table 3: Spodoptera frugiperda - test (foliar application)

[0388]

[0389] * obs. is the observed insecticidal rate

Abstract

The present invention relates to a method for increasing the productive potential of plants and / or for controlling pests in plants having at least one transgenic modification associated with increased yield compared to corresponding wild-type plants, comprising treating plants having The area where at least one transgenic modified plant is planted or is expected to be planted and / or the transgenic plant with at least one transgenic modification or the propagation material of the plant with at least one transgenic modification, said pesticidal composition comprising: Component A, selected from imidacloprid, thiacloprid, clothianidin, acetamiprid, dinotefuran, nitenpyram and thiamethoxam; and component B selected from fipronil and ethiprole.

Description

technical field [0001] The present invention relates to a method for improving the utilization of the production potential of transgenic plants. Background technique [0002] In agriculture, there has been a significant increase in the proportion of genetically modified plants in recent years, even if there are still significant regional differences so far. Thus, for example, the proportion of GM maize in the US has doubled since 2001, from 26% to 52%, whereas in Germany GM maize hardly has any practical importance. But in other European countries, such as Spain, the proportion of genetically modified maize has reached about 12%. [0003] The application of genetically modified plants is mainly to exploit the productive potential of the respective plant species in the most advantageous manner with the lowest input of means of production. The aim of the genetic modification of plants is in particular to produce resistance in plants to certain pests or pests or herbicides as...
