Problems solved by technology

Studies have shown that using promasulfuron-methyl alone as the active ingredient of herbicides still has some shortcomings, for example, the safety of crops is not high enough, and the herbicidal spectrum is not wide enough, which makes it difficult to achieve the weed control effect to a certain extent. not the best

Abstract

The invention relates to a weeding composition, and especially relates to the weeding composition comprising propyrisulfuron and bensulfuron methyl, use of the weeding composition, and a corresponding method of weed control. Active ingredients of the weeding composition comprise the propyrisulfuron and the bensulfuron methyl, wherein a weight ratio of the propyrisulfuron to the bensulfuron methyl 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 bensulfuron methyl. Because the propyrisulfuron has prevention and 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, the prevention and control effect on the weeds is significantly enhanced and a weed killing spectrum is enlarged.

Description

technical field [0001] The present invention relates to a herbicidal composition, in particular to a herbicidal composition containing promasulfuron-methyl and bensulfuron-methyl and 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 certain weeds to develop resistance to the corresponding drugs. So far, many kinds of sulfonylurea compounds have been practically used in paddy fields, usually in the form of a composition formulation containing two or more active ingredients and various sulfonylureas effective for preventing gramineous weeds. Poaceae weed killer. In recent years, however, weeds resistant to sulfonylurea he...
