Abstract
The invention discloses an herbicidal composition comprising clodinafop-propargyl and pyraflufen-ethyl, and an application thereof. According to the herbicidal composition, clodinafop-propargyl and pyraflufen-ethyl are main effective components with a mass ratio of 1-99:1-99. The total mass percentage content of the two in the herbicidal composition is 10-80%. The herbicidal composition provided by the invention can be used in wheat field postemergence weed control, and especially has a significant effect in controlling wheat field grassy weeds and broadleaf weeds. Compared to single agents, with the herbicidal composition, the efficacy is improved, weed resistance is retarded, the herbicidal spectrum is wide, and effect duration is long. The herbicidal composition is safe to wheat and next crops.
Description
Technical field
The invention belongs to technical field of pesticide, especially weed killer herbicide field, be specifically related to the binary built Herbicidal combinations of a kind of clodinafop-propargyl and pyrrole grass ether, this Herbicidal combinations can be applicable to wheat paddock postemergence weed control.
Background technology
Clodinafop-propargyl, has another name called top, chemical name: R-2-[4-(the chloro-3-of 5-fluoro-2-oxygen yl pyridines)-phenoxy group]-propiolic acid, belongs to phenoxy carboxylic acid herbicides, structural formula:
Clodinafop-propargyl is acetyl-CoA carboxylase (ACCase) inhibitor, Uptake and translocation weed killer herbicide, by plant corpus blade and
Leaf sheath absorbs, and phloem conducts, and accumulates and obtains in meristematic tissue in plant corpus, suppresses acetyl-CoA carboxylase, makes fatty acid
Synthesis stops, and the growth division of cell can not normally be carried out, and membranous system etc., containing fat structural deterioration, finally cause Plant death.Be absorbed into weeds Mortality Ratio from clodinafop-propargyl comparatively slow, generally need 1-3 week.
Pyrrole grass ether, have another name called fast careless spirit, red panacea, pyrrole fluorobenzene grass ester, the chloro-5-of chemical name: 2-(the chloro-5-difluoro-methoxy of 4--1-methylpyrazole-3-base)-4-fluorophenoxyacetate ethyl ester, belongs to pyrazoles weed killer herbicide, structural formula:
Pyrrole grass ether is proporphyrinogen oxidase inhibitor, is a kind of novel contact killing type weed killer herbicide.Drug effect is played by the protogen IX accumulation in plant cell.After cauline leaf process, the phase its can be rapidly absorbed in plant tissue, be that plant is downright bad rapidly, or under solar radiation, cauline leaf dewatered withered.Suitable cereal crop is as wheat, barley etc.To cereal crop, there is good selectivity, though the injury having some of short duration, on succession crop noresidue impact, also can make nonselective herbicide.
Current wheat field herbicide limit by crop 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 the uneven residual hazard all easily caused this season crop or succession crop of dispenser.
Summary of the invention
The object of this invention is to provide a kind of Herbicidal combinations containing clodinafop-propargyl and pyrrole grass ether.The present invention selects herbicide to compose different, the clodinafop-propargyl of pluses and minuses complementation and pyrrole grass ether two kinds of weed killer herbicides are made into mixture and use, so both expand herbicide spectrum, significantly improve herbicidal effect, it also avoid and poisoning and the possibility to succession crop generation residual hazard are produced to this season crop.
Another object of the present invention is to provide the application of this Herbicidal combinations in wheat paddock weeding.
Containing a compound weeding composition for clodinafop-propargyl and pyrrole grass ether, this Herbicidal combinations is with the careless ether of clodinafop-propargyl and pyrrole for principle active component, and wherein, the mass ratio of clodinafop-propargyl and the careless ether of pyrrole is 1 ~ 99:1 ~ 99; Preferred: in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and pyrrole grass ether is 1 ~ 80:1 ~ 80; Further preferably: in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and pyrrole grass ether is 1 ~ 60:1 ~ 60; Most preferably: in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and pyrrole grass ether is 29 ~ 60:1 ~ 5.
In technical solution of the present invention, clodinafop-propargyl and the mass percentage of pyrrole grass both ether in Herbicidal combinations are 1 ~ 80%; Preferred clodinafop-propargyl and the mass percentage of pyrrole grass both ether in Herbicidal combinations are 30 ~ 65%.
The Herbicidal combinations of technical solution of the present invention with clodinafop-propargyl and pyrrole grass ether for the auxiliary agent that principle active component and agricultural chemicals allow is mixed with any one formulation.Described formulation is missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule or wetting powder.
Herbicidal combinations of the present invention for the preparation of the application in the weed killer herbicide of wheat paddock postemergence weed control, particularly for the preparation of the application of preventing and kill off in the weed killer herbicide of grass family and broad leaved weed in wheat paddock.
Aforementionedly can be applicable to the not special restriction of weeding auxiliary agent of the present invention, include, but are not limited to alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether, aluminium-magnesium silicate, dimethylbenzene, methyl naphthalene sulfonate formaldehyde condensate, polyoxyethylene nonylphenol ether, aluminium-magnesium silicate, ethylene glycol, tributyl phosphate, silicone oil, sodium metnylene bis-naphthalene sulfonate, ammonium sulfate, polyvinyl alcohol, kaolin, solvent naphtha and water.
Herbicidal combinations of the present invention has the following advantages:
1, activity of weeding is high.Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism, makes Weed Resistance produce speed and reduces, greatly improve the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Pyrrole grass ether is to broad leaved weed in wheat paddock as clearvers, deaf nettle, chickweed, Veronica persica, scentless mayweed etc. have favorable effect, and clodinafop-propargyl can prevent and treat most of grassy weed.After both mixing, the control to multiple broad leaved weed and grassy weed can be improved.
3, safety is high.Because its using dosage is under control, make medicament under the prerequisite that improve drug effect, it have also been obtained raising to the safety of wheat and succession crop.
Herbicidal combinations of the present invention, is applied to wheat paddock postemergence weed control, and it can prevent and kill off various broad leaved weed and grassy weed in wheat paddock, under the prerequisite that improve drug effect, all has safety to wheat and succession crop.
Therefore, Herbicidal combinations of the present invention can be applied in the weed killer herbicide for the preparation of wheat paddock postemergence weed control, particularly applies in for the preparation of the weed killer herbicide preventing and kill off grassy weed and broad leaved weed in wheat paddock.
