Abstract
The invention discloses a weeding composition containing clodinafop-propargyl and flupoxam and application thereof. The weeding composition takes clodinafop-propargyl and flupoxam as the main effective components, clodinafop-propargyl and flupoxam are in a mass ratio of 1-99:1-99, and the two accounts for 10-80% of the total mass of the weeding composition. The weeding composition provided by the invention can be used for wheat field post-emergence weeding, and especially has significant effect for control of graminaceous weeds and broadleaf weeds in wheat field. Compared with a single agent, under the premise of improving the efficacy, the weeding composition provided by the invention delays the weeding resistance, has wide weeding spectrum and long duration, and also has safety to wheat and succeeding 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 flupoxam, 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 blade and the leaf sheath absorption of plant corpus, phloem conducts, and accumulates and obtains in meristematic tissue in plant corpus, suppresses acetyl-CoA carboxylase, fatty acid is synthesized stop, 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.
Flupoxam, has another name called amine grass azoles, amine grass ether, chemical name: 1-[between the chloro-Α of 4--(2,2,3,3,3-five fluorine propoxyl group) tolyl]-3-carbamoyl-5-phenyl-1H-1, and 2,4-triazole, belongs to triazolylamide weed killer herbicide, structural formula:
Flupoxam is mitotic inhibitor, and by suppressing the synthesis of branched-chain amino acid to make protein biosynthesis block, plant stops growing.Postemergence application can make plant stop growing gradually, until growing point is dead, shoot is withered.Not moving in plant, mainly through tagging meristematic tissue and working, therefore imposing on mushroom plant then very effective.
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.Therefore, the present invention selects herbicide to compose different, be made into mixture after the clodinafop-propargyl of pluses and minuses complementation and flupoxam two kinds of suitable decrements of weed killer herbicide to 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.
Summary of the invention
The object of this invention is to provide a kind of Herbicidal combinations containing clodinafop-propargyl and flupoxam.
Another object of the present invention is to provide the application of this Herbicidal combinations in wheat paddock weeding.
Containing a Herbicidal combinations for clodinafop-propargyl and flupoxam, this Herbicidal combinations is with clodinafop-propargyl and flupoxam for principle active component, and wherein, the mass ratio of clodinafop-propargyl and flupoxam is 1 ~ 99:1 ~ 99; Preferably in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and flupoxam is 1 ~ 80:1 ~ 80; In this Herbicidal combinations preferred, the mass ratio of clodinafop-propargyl and flupoxam is 1 ~ 60:1 ~ 60 further; Most preferably in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and flupoxam is 29 ~ 60:1 ~ 5.
The Herbicidal combinations containing clodinafop-propargyl and flupoxam described in technical solution of the present invention, both clodinafop-propargyl and the flupoxam mass percentage in Herbicidal combinations is 1 ~ 80%; Preferably, the mass percentage both clodinafop-propargyl and flupoxam in Herbicidal combinations is 30 ~ 65%.
The Herbicidal combinations containing clodinafop-propargyl and flupoxam described in technical solution of the present invention, this Herbicidal combinations with clodinafop-propargyl and flupoxam 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.
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.
The application of Herbicidal combinations in the weed killer herbicide for the preparation of wheat paddock postemergence weed control containing clodinafop-propargyl and flupoxam described in technical solution of the present invention.
The Herbicidal combinations containing clodinafop-propargyl and flupoxam described in technical solution of the present invention is for the preparation of the application of preventing and kill off in the weed killer herbicide of grassy weed and broad leaved weed in wheat paddock.
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.Flupoxam has good preventive effect to broad leaved weed in wheat paddock, 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.
