Benefits of technology

The patent text describes a way to improve the use of genetically modified plants. This is achieved by treating the plants with a mixture of two specific chemicals, which can be applied to different parts of the plant. This treatment can lead to increased productivity and improved quality of the plants. The word "plant parts" includes all the different parts of a plant, including leaves, stems, and roots, as well as any harvested material or propagation material.

Problems solved by technology

Thus, for example, the proportion of transgenic maize in the USA has doubled from 26% to 52% since 2001, while transgenic maize has hardly been of any practical importance in Germany.

Leaf Application for Aphis gossypii / Cotton

[0124]Individually potted transgenic cotton plants with Lepidoptera resistance and herbicide resistance (line DP444 BG / RR) are treated with the desired product against the cotton aphid (Aphis gossypii).

[0125]After the desired time, the kill in % is determined. 100% means that all the aphids were killed; 0% means that no aphids were killed.

[0126]Compared with the control plants not treated according to the invention, a distinct improvement in the control of the pests is evident.

Abstract

The invention relates to a method for controlling pests using a combination of insecticides and transgenic plants and consequently improving the utilization of the production potential of transgenic plants which comprises treating the plant with active compound combinations comprising an active compound from the group of the anthranilamides and at least one further insecticide.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a Divisional application of U.S. application Ser. No. 12 / 596,184, filed Oct. 16, 2009, which is a §371 National Stage Application of PCT / EP2008 / 003104, filed Apr. 14, 2008, which claims priority to German Application No. 10 2007 018 452.4, filed Apr. 17, 2007, the content of all of which are incorporated herein by reference in their entireties.BACKGROUND[0002]1. Field of the Invention[0003]The invention relates to a method for controlling pests using a combination of insecticides and transgenic plants and consequently improving the utilization of the production potential of transgenic plants.[0004]2. Description of Related Art[0005]In recent years, there has been a marked increase in the proportion of transgenic plants in agriculture, even if regional differences are still noticeable to date. Thus, for example, the proportion of transgenic maize in the USA has doubled from 26% to 52% since 2001, while transgenic maize ...
