Abstract

The invention provides weeding composition. The weeding composition comprises active ingredients as follows: propyrisulfuron, pyraclonil and MCPA in a weight ratio being (1-10):(1-20):(10-100). The invention further relates to an application of the weeding composition in control for growth of undesirable plants such as monocotyledonous and dicotyledonous weeds, in particular to an application of the weeding composition in control for undesirable plants in grain crops. The invention further provides a method for controlling growth of the undesirable plants. The method comprises the step as follows: the effective amount of the weeding composition is contacted with the undesirable plants or growing places of the undesirable plants, or the effective amount of the weeding composition is appliedto soil to prevent the undesirable plants from germination or growth.

Description

technical field [0001] The invention belongs to the field of pesticides; the invention relates to a herbicidal composition; the invention also relates to a method for controlling unwanted plant growth. Background technique [0002] The control of agricultural weeds has always been the most concerned and important issue in agricultural production. Protecting crops from weeds and other vegetation that inhibit crop growth is an ongoing problem in agriculture. [0003] The use of chemical herbicides is one of the important symbols of modern agriculture. In recent years, the sales volume of herbicides has increased year by year, and the application area has also expanded year by year. However, with the continued use of many herbicide varieties on a large scale, many problems have arisen, such as the problem of weed resistance, especially the problem of resistance to older weeds is particularly prominent; Issues such as short validity periods are also prominent. Therefore, it ...
