Sarmentine-containing herbicidal composition and application thereof

Abstract Disclosed is a sarmentine-containing herbicidal composition and use thereof, wherein the 5 composition includes a sarmentine and a clomeprop at a weight ratio of (1:2)-(8:1); the sarmentine is a plant-derived herbicide, having low toxicity and being environmentally friendly; in the present invention, it is found that the compound of sarmentine and clomeprop has a synergistic effect, and the combined use of the two cures the deficiency that clomeprop has a poor prevention and control effect on Gramineae weedswhile the sarmentine has a poor prevention and control effect on 10 Cyperaceae weeds; moreover, the compound can delay a weed resistance, and has a high control efficiency and a broad-spectrum activity. The combined use of the sarmentine and the clomeprop shows an herbicidal effect superior to that achieved by using sarmentine or clomeprop alone, which leads to a decrease in an amount of the herbicide used, thereby reducing an adverse effect of agrochemicals on the environment.
