Embodiment Construction
[0030] In order to make the technical solutions, objectives and advantages of the present invention clearer, the present invention is described with the following specific examples, but the present invention is not limited to these examples. The effect experiment of the present invention adopts the mode of field test, and unless otherwise specified, the ratios mentioned below are all ratios of parts by mass.
[0031] field efficacy test
[0032] The test was carried out in the wheat field test base in Henan Province. The soil fertility was consistent and medium. The humidity was moderate during the test. The main weeds in the test site were pigtails, brome, etc., and the weeds were evenly distributed. The test results are as follows:

Abstract
Provided is a herbicidal composition containing saflufenacil, glyphosate and fluazifop-p-butyl. A mass ratio of effective components including the saflufenacil, the glyphosate and the fluazifop-p-butyl in the herbicidal composition is 1-50:0.1-20:0.1-20; a total mass of the effective components in the composition accounts for 1%-60% of a total mass of the composition, and the rest components are permitted and acceptable auxilairy components in pesticide; and the formulation form of the herbicidal composition can be emulsifiable concentrate, suspension concentrate, wettable powder, water dispersible granules, aqueous emulsion, microemulsion, granules, microcapsules or water aqua. Main weeds in rice fields, such as barnyard grass, leptochloa chinensis, digitaria sanguinalis and goosegrass herbs, and winter wheat weeds such as amur foxtail, avena fatua, polypogon fugax, bluegrass, sclerochloa dura, puccinellia tenuiflora, Italian ryegrass, lolium temulentum, bromegrass, phleum paniculatum huds, aegilops tauschii, beckmannia syzigachne, wheatgrass, shepherd's purse, descurainia sophia and crickweed, can be prevented and removed effectively.
Description
technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing saflufenacil, glyphosate and fluazifop-p-p. Background technique [0002] Saflufenacil is a uracil herbicide developed by BASF. Its chemical name is N-[2-chloro-4-fluoro-5-(3-methyl-2,6-dione-4-(trifluoromethyl)-3,6-dihydro-1(2H) Pyrimidinyl) phenyl]-N-isopropyl-N-methanesulfonamide, can be used as a herbicide for killing, can effectively control a variety of broadleaf weeds, including resistance to glyphosate, ALS and triazines sex weed. It has a fast killing effect and the soil residues degrade rapidly. It can be used to control broad-leaved weeds in wheat fields. [0003] Glyphosate mainly hinders the biosynthesis of aromatic amino acids, that is, the synthesis of phenylalanine, tryptophan and tyrosine through the shikimic acid pathway. It inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSP synthase), which catalyze...
