Problems solved by technology

[0008] However, with the continued 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 and other herbicides 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) The herbicide variety has a single effect and a short duration of action

Abstract

The invention provides a weeding composition. Active components of the weeding composition consist of a component A and a component B, wherein the component A is halosulfuron-methyl and the component B is other herbicide; the weight ratio of the component A to the component B is 1:1 to 1:100. The invention also relates to the application of the weeding composition to prevention and control of the growth of undesired plants such as broadleaf weed, sedge weed or grassy weed, in particular to the application of the weeding composition to prevention and control of the growth of undesired plants such as echinolchloacrus-galli, leptochloa chinensis, yellow nut sedge, cyperus difformis L, Solanum nigrum L, abutilon, acalypha australis, Scirpus juncoides Roxb and Alisma L in cereal crops. The invention also provides a method for preventing and controlling the growth of the undesired plants. The method comprises the following steps: contacting the undesired plants or growth places thereof with the weeding composition with weeding effective quantity, or applying the weeding composition with weeding effective quantity to soil or water to prevent germination or growth of the undesired plant.

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 undesirable plant growth. Background technique [0002] The world's food production suffers huge losses every year due to diseases, insect pests, and weeds. Crops are attacked by various weeds almost throughout the entire growing season. Weed damage is also a key factor restricting crop yields. Therefore, the prevention and 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 inhibits crop growth is an ongoing problem in agriculture. To address this problem, many chemicals and chemical agents to control weed growth are already in commercial use. [0004] Rice is one of the world's major food crops. Nearly half of the world's population, including almost the entire population of East and Sout...
