[0015] However, with the continuous use of many herbicide varieties in large areas of rice fields, many problems have also arisen: (1) Weed resistance is outstanding, among which the resistance of barnyardgrass to propanil and butachlor is more prominent , and the resistance of Cyperaceae weeds to sulfonylurea herbicides has gradually emerged; (2) The damage of older weeds and perennial weeds has become an important problem, especially older barnyard grass and Cyperaceae perennial weeds. Not outstanding; (3) Herbicide varieties have a single effect and short duration

Abstract
The invention provides a weeding composition, which has active components including halosulfuron-methyl and metamifop, wherein the weight proportion of the halosulfuron-methyl to the metamifop is 100:1 to 1:100. The invention also relates to application of the weeding composition on preventing and controlling undesirable plant growth of broadleaf weeds, cyperaceae weeds or gramineous weeds, in particular to application of the weeding composition on preventing and controlling undesirable plant growth of Echinolchloacrus-galli (ECHCG), Leptochloa chinensis (LEFCH) and Cyperus difformis L. The invention also provides a method for preventing and controlling undesirable plant growth. The method comprises the step of enabling undesirable plants or growth places thereof to contact the weeding composition provided by the invention with weeding effective quantity, or applying the weeding composition provided by the invention with weeding effective quantity in soil or water to prevent the undesirable plants from sprouting or growing.
Description
technical field [0001] The present invention belongs to the field of pesticides, and in particular relates to a herbicidal composition and a method for controlling unwanted plant growth. Background technique [0002] The world's food production suffers huge losses due to diseases, insects, and weeds every year, and crops are almost always attacked by various weeds throughout the growing season, and the damage of weeds is also a key factor restricting crop yields. Therefore, the control of agricultural weeds has always been the most concerned and important issue in agricultural production. [0003] Protecting crops from weeds and other vegetation that inhibit crop growth is an ongoing problem in agriculture. To address this problem, many chemicals and chemical formulations to control weed growth have been used commercially. [0004] Rice is one of the main food crops in the world. Nearly half of the world's population, including almost the entire population of East Asia and...
