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 compositions for combating undesired vegetation in crop plants. Background technique [0002] When herbicides are used alone, their effect is usually only temporary, ie resistance in weeds is observed after a certain period of time. In crop protection, it is in principle desirable to increase the activity and reliability of action of active compounds. It is particularly desirable that the active compounds be effective in controlling undesired vegetation, but at the same time be compatible with the useful plants concerned. It is therefore desirable that the active compounds can be used at the lowest possible application rates in order to achieve the highest possible compatibility with the useful plants. [0003] Sulfonylurea herbicides are selective systemic herbicides, which can be absorbed by the roots and leaves of weeds, conduct r...
