Abstract
The invention discloses a weeding composition containing clodinafop-propargyl and flamprop-methyl and application of the weeding composition. Clodinafop-propargyl and flamprop-methyl serve as main effective components of the weeding composition, the mass ratio of clodinafop-propargyl to flamprop-methyl is 1-99 to 1-99, and the mass percent of clodinafop-propargyl and flamprop-methyl 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 of a kind of clodinafop-propargyl and flamprop methyl 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.
Flamprop methyl ester, chemical name: N-benzoyl-N-(the chloro-4-fluorophenyl of 3-)-D-alanine methyl esters, belongs to acetamide-group herbicides, structural formula:
Flamprop methyl 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 containing clodinafop-propargyl and flamprop methyl ester.
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 flamprop methyl ester, this Herbicidal combinations is with clodinafop-propargyl and flamprop methyl ester for principle active component, and wherein, the mass ratio of clodinafop-propargyl and flamprop methyl ester is 1 ~ 99:1 ~ 99; Preferably in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and flamprop methyl ester is 1 ~ 80:1 ~ 80; In this Herbicidal combinations preferred, the mass ratio of clodinafop-propargyl and flamprop methyl ester is 1 ~ 60:1 ~ 60 further; Most preferably in this Herbicidal combinations, the mass ratio of clodinafop-propargyl and flamprop methyl ester is 29 ~ 60:1 ~ 5.
The Herbicidal combinations containing clodinafop-propargyl and flamprop methyl ester described in technical solution of the present invention, the mass percentage wherein both clodinafop-propargyl and flamprop methyl ester in Herbicidal combinations is 1 ~ 90%; Both preferred clodinafop-propargyl and the flamprop methyl ester mass percentage in Herbicidal combinations is 30 ~ 65%.
In the binary built composition of clodinafop-propargyl of the present invention and flamprop methyl ester, except the active ingredient such as clodinafop-propargyl and flamprop methyl 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.
