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

The invention provides weeding composition containing clodinafop-propargyl, flucarbazone-sodium and florasulam, wherein the mass ratio of clodinafop-propargyl, flucarbazone-sodium and florasulam as effective components in the weeding composition is (1-50): (0.1-20): (0.1-20), the total mass of the effective ingredients in a preparation accounts for 1%-60% of the mass of the whole preparation, andthe balance is auxiliary components which are allowed to be used and accepted in pesticides. The weeding composition can effectively control main weeds in paddy fields, for example, barnyard grass, leptochloa chinensis, crabgrass, goosegrass as well as winter wheat weeds including alopecurus aequalis, wild oats, polypogon, bluegrass, sclerochloa kengiana, puccinellia, lolium multiflorum, lolium temulentum, bromegrass, phleum paniculatum huds, aegilops tauschii, beckmannia syzigachne, agropyron cristatum, capsella bursa-pastoris, descurainia sophia, malachium aquaticum and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing clodinafop-propargyl, flucarbasulfuron-methyl and florasulam. Background technique [0002] Clodinafop-propargyl (CAS number: 105512-06-9; chemical name: R-2-[4-(5-chloro-3-fluoro-2-oxypyridine)-phenoxy]-propionic acid Propargyl ester) is developed and developed by ciba-Geigy Company, belongs to aryloxyphenoxypropionic acid herbicides, can effectively inhibit the biosynthesis of esters as acetyl cosensitizing A hydroxylase inhibitor, clodinafop-propargyl is very common in soil Rapidly degraded into free acid phenyl and pyridine part into the soil. It is mainly used for the control of wild oats, oats, oats, ryegrass, common bluegrass, foxtail, etc. [0003] Flucarbasulfuron-methyl is a systemic high-efficiency wheat field herbicide of the sulfonylurea type, which has obvious control effects on grassy weeds such as wild oats, brom...
