Abstract
The invention discloses a kind of flumetsulam containing benzene and the mixed herbicide of pinoxaden, for the herbicide using benzene flumetsulam and pinoxaden as principle active component, the mass ratio of benzene flumetsulam and pinoxaden is 0.1~80：0.1~80.Application of the mixed herbicide of the present invention in wheat paddock postemergence weed control, there is wide spectrum, quick-acting, efficient, less toxic, safety and environmental protection.
Description
Technical field
This patent belongs to technical field of pesticide, especially herbicide field, is related to the two of benzene flumetsulam and pinoxaden
First built agent.The herbicidal composition can be applied to wheat paddock postemergence weed control.
Background technology
Benzene flumetsulam (saflufenacil), molecular formula：C17H17ClF4N4O5S, chemical name：[the chloro- 4- of 2- are fluoro- by N'-
5- (1,2,3,6- tetrahydrochysene -3- methyl -2,6- dioxy -4- trifluoromethyl pyrimidine -1- bases) benzoyl]-N- isopropyl-N- methyl
Sulfonamide, it is the uracil weeding agent developed by BASF AG, is proporphyrinogen oxidase (PPO) inhibitor, it is pressed down
Cell membrane is destroyed after system, is caused cell seepage, necrosis, is ultimately resulted in plant death.Steriland herbicide can be used as to use,
A variety of broad leaved weeds can effectively be prevented and kill off, including to glyphosate, ALS and triazines produce the weeds of resistance, it is also possible in wheat paddock
Prevent and treat broad leaved weed.
Pinoxaden (pinoxaden), chemical name：2,2- dimethyl-propiolic acid 8- (2,6- diethyl -4- methyl-benzene
Base) -9- oxygen -1,2,4,5-4 hydrogen -9H- pyrazoles [1,2-d] [1,4,5] oxygen phenodiazine Zhuo -7- base esters.Belong to neophyl pyrazoles weeding
Agent, the mechanism of action are acetyl-CoA carboxylase inhibitor, cause aliphatic acid biosynthesis block, stop cell division, cell
Film is destructurized containing fat, causes weeds dead.With uptake and translocation, being mainly used in wheatland, to prevent and kill off annual gramineae miscellaneous
Grass, such as there is good preventive effect to wild oat, green bristlegrass, barnyard grass.
By the screening of different pesticide species compounded formulas, rational formula is filtered out, can be effectively improved to disease pest and weed
Actual prevention effect, expand preventing and treating spectrum, reduce dosage, reduce cost, mitigate the pollution to environment, delay disease pest and weed to resist
The generation of the property of medicine, it is the important means of the agriculturally disease pest and weed comprehensive regulation.
The content of the invention
It is an object of the invention to provide a kind of flumetsulam containing benzene and the mixed herbicide of pinoxaden.
It is a further object of the present invention to provide application of the herbicide in wheat paddock weeding.
The mixed herbicide of a kind of flumetsulam containing benzene and pinoxaden, the herbicide is with benzene flumetsulam and pinoxaden
For principle active component, the mass ratio of benzene flumetsulam and pinoxaden is 0.1~80：0.1~80.It is preferred that benzene flumetsulam with
The mass ratio of pinoxaden is 1~60：1~60, more preferably 2~14：1.
In mixed herbicide, benzene flumetsulam is 1% with weight/mass percentage composition of both pinoxadens in herbicide
~85%, preferred mass percentage composition is 6%~75%, more preferably 20%~75%.
In the benzene flumetsulam of the present invention and the binary built preparation of pinoxaden, except benzene flumetsulam and pinoxaden
Outside etc. active ingredient, the conventional surfactants allowed on pesticidal preparations, thickener, solvent or solid packing etc. can also be added
Auxiliary agent is configured to any one formulation allowed on agricultural chemicals.It is preferred that it is processed into missible oil, suspending agent, aqueous emulsion, microemulsion, wettable
Pulvis, water dispersible granules.
Application of the mixed herbicide of the present invention in wheat paddock weeding, the grass family especially in wheat paddock is prevented and kill off
Weeds and the application of broad leaved weed, there is broad weed-killing spectrum, quick, low, the less toxic, safety and environmental protection of residual, be high-quality
Wheat crop chemical herbicide.
" % " of the present invention is weight/mass percentage composition.
Compared to the prior art, beneficial effects of the present invention：
The combinations of herbicides of the present invention, have broad weed-killing spectrum, quick, efficient, less toxic, the low, safety and environmental protection of residual etc. excellent
Point, it is possible to reduce pesticide usage amount, reduce residues of pesticides, the advantages that Environmental compatibility is good, to person poultry safety, is high-quality wheat
Crop chemistry herbicide.
1st, activity of weeding is high.The Herbicidal combinations of the present invention can kill weeds by two kinds of different mechanism so that weeds
Resistance produces speed and reduced, and effective ingredient consumption reduces, but drastically increases the removing activity of herbicide.
2nd, herbicidal spectrum is wide, lasting period length.Benzene flumetsulam is uracil weeding agent, is proporphyrinogen oxidase (PPO)
Inhibitor, cell membrane is destroyed after it is suppressed, and is caused cell seepage, necrosis, is ultimately resulted in plant death.Pinoxaden
The mechanism of action is acetyl-CoA carboxylase inhibitor, causes aliphatic acid biosynthesis block, stops cell division, cell membrane
It is destructurized containing fat, cause weeds dead.Both mechanisms are different, and after both mix, herbicidal spectrum is wider, can prevent and kill off
Grassy weed and broad leaved weed in wheat paddock.
3rd, it is safe.Because the use content of various active ingredients reduces, medicament is set to improve the premise of drug effect
Under, residues of pesticides are reduced, it also avoid also being improved to wheat and succession crop security, avoid agricultural chemicals to people
Livestock products give birth to the possibility of residual hazard.
