Abstract

The present invention relates to a herbicidal composition. The invention also relates to the use of said herbicidal composition for combating undesirable vegetation in crop plants. The invention provides a herbicidal composition, which contains the active components promisulfuron and pyrimidine, and the weight ratio of pyrimisulfuron and pyrimidine is 100:1 to 1:100. Application of the herbicidal composition of the present invention in controlling monocotyledonous weeds and dicotyledonous weeds. The present invention also provides a method for controlling undesirable plants. The active ingredients of the herbicidal composition are applied to undesirable plants, plant propagation materials, or to undesirable plants or plant propagation materials. Areas where unwanted vegetation grows.

Description

Technical field [0001] The present invention relates to a herbicidal composition. The invention also relates to the use of said herbicidal composition for combating undesirable vegetation in crop plants. Background technique [0002] When herbicides are used alone, their effects are usually only temporary, i.e. weed resistance is observed after a certain period of time. In crop protection, it is in principle desirable to increase the activity of active compounds and the reliability of their effects. It is particularly desirable for the active compounds to be effective against undesirable plants but at the same time compatible with the useful plants of concern. It is therefore desirable that the active compounds be used at the lowest possible application rates, achieving the highest possible compatibility with the useful plants. [0003] Sulfonylurea herbicides are selective systemic herbicides that can be absorbed by the roots and leaves of weeds and are rapidly transmitt...
