A mass ratio of diflufenican to sulfentrazone in the mixed herbicide is 1-70: 1-20. The total mass of diflufenican and sulfentrazone is 6-75% that of the mixed herbicide. The mixed herbicide can prevent and remove various gramineous weed and broadleaf weed in the wheat field. The mixed herbicide has the advantages of high weeding activity, wide weeding spectrum, lasting action, high safety, high efficiency, wide spectrum, good environmental compatibility and good safety to human and animals and can be used as a high-quality chemical herbicide for wheat.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of mixed herbicide including diflufenican and sulfentrazone two kinds of active ingredients, and the preparation method and application of this kind of mixed herbicide.
Background technology
Diflufenican (diflufenican), chemical name: N-(2,4-difluorophenyl)-2-[(3-trifluoromethyl) phenoxy group]-3-pyridine anilide.This medicine belongs to herxheimer-liked reaction inhibitor, and absorb carotenoid content in the weeds plant of medicament and decline, cause Destruction of Chlorophyll and cell rupture, weeds show as young shoot decolouring or white, and last plant wilt is dead.Be mainly used in corn, soybean and wheatland and prevent and kill off multiple annual gramineous weed and some broad leaved weed.Especially to be clearvers, Veronica removal effect obvious.
Sulfentrazone (sulfentrazone), chemical name: 2 ', 4 '-two chloro-5 '-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxygen-1H-1,2,4-triazol-1-yl) methylsulfonylphenylamine.Triazolineone weed killer herbicide, proporphyrinogen oxidase inhibitor.By suppressing proporphyrinogen oxidase in chlcrophyll biosynthesis process, be produce excessive protoporphyrin IX in plant cell, the latter is sensitising agent, cause producing active oxygen in cell, cell membrane, tonoplast etc. is finally caused to break, cellular content depths, withered dead.Soil half life period 110-280 days, cauline leaf process, soil treatment.Can prevent and treat lead a cow, Amaranthus retroflexus, acalypha copperleaf, lamb's-quarters, datura, guest continent knotweed, lady's-grass, green foxtail, Siberian cocklebur, eleusine indica, earth almona, annual broadleaf weed, grassy weed and the nutgrass flatsedge etc. such as the rhizome of nutgrass flatsedge.
Current weeding for wheat agent limit by safety, herbicide spectrum is also limited, be used alone the generation that a kind of weed killer herbicide single dose can not control weeds of wheat completely effectively, moreover some weed killer herbicide is due to water-soluble large or the field lasting period is oversize, consumption is excessive or dispenser is uneven all easily causes residual hazard.
