Problems solved by technology

[0010] However, the current common practice in the industry is to use promasulfuron-methyl alone as the active ingredient of herbicides to prepare herbicides, and there has been no technology to mix promasulfuron-methyl with other active ingredients.
Studies have shown that there are still some deficiencies in using promasulfuron-methyl alone as the active ingredient of herbicides, for example, the safety of crops is not high enough, the herbicidal spectrum is not wide enough, etc., which makes it difficult to achieve the best weed control effect

Abstract

The invention relates to a weeding composition, and especially relates to the weeding composition containing propyrisulfuron and bispyribac sodium, use of the weeding composition and a corresponding weed control method. Active ingredients of the weeding composition comprise the propyrisulfuron and the bispyribac sodium, wherein a ratio of the propyrisulfuron to the bispyribac sodium, by weight percentage, is ranged from 100:1 to 1:100. 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 through complex formulation of herbicides comprising the propyrisulfuron and the bispyribac sodium. Because the propyrisulfuron has prevention and control ability 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. The weeding composition shows a significantly enhanced control effect on the weeds in the crop growth environment, compared with single use of one herbicide.

Description

technical field [0001] The present invention relates to a herbicidal composition, in particular to a herbicidal composition containing promasulfuron-methyl and bispyribac 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 herbicides...
