Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of U.S. patent application Ser. No. 12 / 540,244 (the entire disclosure of which is incorporated herein by reference), filed on Aug. 12, 2009, which claim priority to German Application No. 10 2008 037 631.0 filed Aug. 14, 2008.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is in the technical field of crop protection compositions which can be used against unwanted vegetation, for example by the pre-sowing method (with or without incorporation), by the pre-emergence method or by the post-emergence method in sown or planted crop plants such as, for example, in wheat (durum wheat and common wheat), corn, soybeans, sugar beet, sugar cane, cotton, rice (planted or sown under upland or paddy conditions using indica or japonica varieties and also hybrids / mutants / GMOs), beans (such as, for example, bush beans and broad beans), flax, barley, oats, rye, triticale, ...

AI Technical Summary

Benefits of technology

The present invention provides herbicide combinations that can be used to control unwanted vegetation in crop plants. These combinations include dimethoxytriazinyl-substituted difluoromethanesulfonylanilides and herbicides from the group of pyrimidines. These herbicides work together in a synergistic manner, making them more effective than using them alone. The herbicide combinations can be used on a wide range of crop plants, including wheat, corn, soybeans, sugar beet, sugar cane, cotton, rice, and more. The herbicides can also be used on non-crop areas like rice fields or on residential areas. The technical effect of this invention is to provide more effective herbicide combinations for controlling unwanted vegetation in crop plants.

Problems solved by technology

The compensation of losses in action in the case of individual plants by increasing the application rates of the herbicides is only possible to a certain degree, for example because such a procedure reduces the selectivity of the herbicides or because the action is not improved, even when applying higher rates.

However, in the combined use of a plurality of active compounds, there are frequently phenomena of chemical, physical or biological incompatibility, for example lack of stability of a joint formulation, decomposition of an active compound or antagonism in the biological activity of the active compounds.

For these reasons, potentially suitable combinations have to be selected in a targeted manner and tested experimentally for their suitability, it not being possible to safely discount a priori negative or positive results.
