Abstract
The invention discloses a weeding composition containing clodinafop-propargyl and flamprop-isopropyl and application of the weeding composition. Clodinafop-propargyl and flamprop-isopropyl serve as main effective components of the weeding composition, the mass ratio of clodinafop-propargyl to flamprop-isopropyl is 1-99 to 1-99, and the mass percent of clodinafop-propargyl and flamprop-isopropyl in the weeding composition accounts for 10-80% of the total mass percent. The weeding composition can be used for post-seedling weeding of wheat fields, and especially has a remarkable effect on preventing and killing graminaceous weed in the wheat fields. By means of the weeding composition, compared with single agents, on the premise of improving efficacy, weed resistance is delayed, a weeding spectrum is wide, the lasting period is long, and safety is achieved for 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 that a kind of clodinafop-propargyl and wheat straw lie prostrate isopropyl ester, 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.
Wheat straw volt isopropyl ester, chemical name: N-benzoyl-N-(the chloro-4-fluorophenyl of 3-)-D-alanine isopropyl ester, belongs to acetamide-group herbicides, structural formula:
Wheat straw volt isopropyl ester is fatty acid synthetic inhibitor, is mainly used in the weeds such as Control Wild oat, amur foxtail after wheatland seedling.
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 lying prostrate isopropyl ester containing clodinafop-propargyl and wheat straw.
Another object of the present invention is to provide the application of this Herbicidal combinations in wheat paddock weeding.
Lie prostrate a Herbicidal combinations for isopropyl ester containing clodinafop-propargyl and wheat straw, this Herbicidal combinations lies prostrate isopropyl ester for principle active component with clodinafop-propargyl and wheat straw, and wherein, the mass ratio that clodinafop-propargyl and wheat straw lie prostrate isopropyl ester is 1 ~ 99:1 ~ 99; In this Herbicidal combinations preferred, clodinafop-propargyl and wheat straw lie prostrate the mass ratio of isopropyl ester is 1 ~ 80:1 ~ 80; In further preferably this Herbicidal combinations, clodinafop-propargyl and wheat straw lie prostrate the mass ratio of isopropyl ester is 1 ~ 60:1 ~ 60; The mass ratio that most preferably in this Herbicidal combinations, clodinafop-propargyl and wheat straw lie prostrate isopropyl ester is 29 ~ 60:1 ~ 5.
The Herbicidal combinations lying prostrate isopropyl ester containing clodinafop-propargyl and wheat straw described in technical solution of the present invention, wherein clodinafop-propargyl and wheat straw lie prostrate the mass percentage of both isopropyl esters in Herbicidal combinations is 1 ~ 80%; It is 30 ~ 65% that preferred clodinafop-propargyl and wheat straw lie prostrate the mass percentage of both isopropyl esters in Herbicidal combinations.
Clodinafop-propargyl of the present invention and wheat straw are lied prostrate in the binary built composition of isopropyl ester, except clodinafop-propargyl and wheat straw are lied prostrate except the active ingredients such as isopropyl ester, the auxiliary agents such as conventional surfactants, thickener, solvent or the solid packing that pesticidal preparations allows can also be added and be mixed with any one formulation that agricultural chemicals allows.Preferably be processed into missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule, wetting powder etc.
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 etc.
Herbicidal combinations of the present invention can be applied in wheat paddock postemergence weed control, particularly has remarkable result preventing and kill off in wheat paddock application in grassy weed.
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.Wheat straw volt isopropyl ester is broad spectrum weeding agent, and it has good preventive effect to annual gramineous weed, and clodinafop-propargyl can prevent and treat most of grassy weed.After both mixing, the control to 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 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 in wheat paddock.
