Abstract
The present invention provides a weeding composition. The weeding composition consists of the active ingredients of halosulfuron-methyl and pendimethalin. The weight ratio of the halosulfuron-methyl to the pendimethalin is (10:1)-(1:100). The present invention also relates to the use of the weeding composition in preventing and controlling the growth of undesirable plants of broadleaf weeds, cyperaceae weeds or gramineous weeds, particularly in the preventing and controlling the growth of the undesirable plants of echinolchloacrus-galli (ECHCG), leptochloa chinensis (LEFCH), and cyperus difformis L in grain crops. The present invention also provides a method for controlling and preventing the undesirable plants. The method enables the undesirable plants or growing site thereof to contact with the weeding composition at an effective weeding amount, or applies the weeding composition at the effective weeding amount to the soil or water to prevent the germination or growth of the undesirable plants.
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] Clopyrazosulfuron-methyl (Halosulfuron-methyl, CAS NO. 100784-20-1) is a sulfonylurea herbicide. The pure product is a white powdery solid with...
