Abstract

The invention relates to a weeding composition. The weeding composition is composed of three active ingredients including glufosinate-ammonium, oxyfluorfen and topramezone, auxiliary agents and an excipient, wherein the weight percent ratio of glufosinate-ammonium to oxyfluorfen ranges from 1:3 to 3:1; the weight ratio of glufosinate-ammonium or oxyfluorfen to topramezone ranges from 5:1 to 1:5; the weight of glufosinate-ammonium, oxyfluorfen and topramezone accounts for 10%-90% of the total weight of the weeding composition. The weeding composition is applicable to soil of undesired vegetations and stems and leaves of the undesired vegetations, or grass burning carried out before crops are planted or before emergence of seedlings of sowed seeds and post-treatment of seedlings of tolerance crops and non-tolerance crops. According to the weeding composition, the high synergistic interaction effect can be achieved, the generation of weed drug resistance is overcome or delayed, the herbicide controlling spectrum is expanded, the pesticide utilization cost is reduced and the toxicity is lowered.

Description

technical field [0001] The present invention relates to a herbicidal composition. Background technique [0002] With the change of farming system and the increasing demand of economic crops, especially during the long-term use of pesticides, crops have developed resistance, which greatly reduces the efficacy of pesticides. At the same time, the protection of crops from undesired vegetation which inhibits crop growth is a recurring problem in agriculture from time to time. To help address this problem, researchers in the field of synthetic chemistry have produced a variety of chemicals and chemical formulations that are effective in controlling the growth of such unwanted vegetation. Many types of chemical herbicides have been described in the literature, and many are in commercial use. [0003] In some cases it has been shown that the herbicidally active ingredients are more effective when applied in combination than when applied individually, this is referred to as "syner...
