Abstract

The invention relates to a weeding composition and further relates to application of the weeding composition to resistance to weeds in crops. The weeding composition provided by the invention comprises following active components: propyrisulfuron and pyribenzoxim, wherein the weight ratio of propyrisulfuron to pyribenzoxim is (100:1)-(1:100). The invention further relates to application of the weeding composition to prevention and removal of monocotyledonous weeds and dicotyledonous weeds and a method for preventing and removing weeds. According to the method, the active components, namely propyrisulfuron and pyribenzoxim, of the weeding composition are together or separately applied to weeds, plant propagation materials or weed growth areas.

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 transmi...
