Problems solved by technology

Studies have shown that using promasulfuron-methyl alone as the active ingredient of herbicides still has some deficiencies, for example, the safety of crops is not high enough, the herbicidal spectrum is not wide enough, and the drug residue effect is poor, which leads to weed control. The effect is difficult to achieve the best

Abstract

The invention relates to a weeding composition, and especially relates to the weeding composition comprising propyrisulfuron and bentazone, use of the weeding composition, and a corresponding weed control method. Active ingredients of the weeding composition comprise the propyrisulfuron and the bentazone, wherein a weight ratio of the propyrisulfuron to the bentazone is 200:1 to 1:200. The weeding composition is used for control of gramineae weeds, broadleaf weeds and cyperaceae weeds in crop growth environment. According to the invention, the weeding composition is prepared by complex formulation of herbicides comprising the propyrisulfuron and the bentazone. Because the propyrisulfuron has control capability to weeds that show resistance to known sulfonylurea herbicides, and the weeding composition is prepared by binary complex formulation of the two herbicides, the weeding composition has an enhanced effect. Compared with single use of one herbicide, a weed killing spectrum is enlarged and control effect on the weeds is significantly enhanced.

Description

technical field [0001] The present invention relates to a herbicidal composition, in particular to a herbicidal composition containing promasulfuron-methyl and bentazone, its use, and a corresponding weed control method. Background technique [0002] At present, in order to improve the growth quality of crops, the industry is constantly working on the development of herbicides with high herbicidal effect, wide herbicidal spectrum, low toxicity, low residue, and excellent crop selectivity. In the production environment of crops, long-term use of certain herbicides will cause some weeds to develop resistance to the corresponding drugs. So far, many kinds of sulfonylurea compounds have been actually used in rice fields, and the most widely used ones are Composition preparation form, the preparation contains two or more active ingredients and various grass weed killers effective for preventing grass weeds. In recent years, however, weeds resistant to sulfonylurea herbicides suc...
