Abstract

The invention discloses a mixed herbicide with saflufenacil and isoproturon. According to the mixed herbicide, the saflufenacil and the isoproturon serve as main effective components, and the mass ratio of the saflufenacil to the isoproturon is (1-80):(1-80). The mixed herbicide is applied to wheat-paddock post-seedling weeding, and has the advantages of being broad in spectrum, quick in effect taking, efficient, lowly toxic, safe, environmentally friendly and the like.

Description

A kind of containing the mixed herbicide of benzene flumetsulam and isoproturon
Technical field
The invention belongs to technical field of pesticide, especially weedicide field, it relates to the binary built agent of benzene flumetsulam and isoproturon. This herbicidal composition can be applicable to wheat paddock postemergence weed control.
Background technology
Benzene flumetsulam (saflufenacil), chemical name: N'-[the chloro-4-of 2-fluoro-5-(3-methyl-2,6-bis-oxygen-4-(trifluoromethyl)-3,6-two hydrogen-1 (2H)-pyrimidine) benzoyl]-N-sec.-propyl-N-methyl sulphamide. Benzene flumetsulam is the uracil weeding agent developed by BASF company, is proporphyrinogen oxidase (PPO) inhibitor. Can be used as steriland herbicide use, can effectively prevent and kill off multiple broadleaf weeds, comprise glyphosate, ALS and triazines produce the weeds of resistance. Have and very fast go out raw effect and pedo relict degraded rapidly. May be used for control wheat paddock broadleaf weeds or mixed with gramineous weed weedicide, such as glyphosate, effect is fine, all can use in various crop field and bare place, and wheel is restricted little.
Isoproturon (isoproturon), chemical name: 3-p-cumyl-1,1-dimethyl urea; N'-(4-cumyl)-N, N-dimethyl urea, isoproturon, for disturbing the photosynthetic phenyl ureagroup herbicides of weeds for selectivity, can use before bud, after bud. For wheat, barley, cotton, corn, soybean, pea, broad bean, prevent and kill off annual gramineous weed and broadleaf weeds peanut and other crops, the weeds such as such as amur foxtail, lady's-grass, wild avena sativa, lamb's-quarters, annual bluegrass, the effects such as flat storage, grass of walking alone, Motherwort Herb, Herba Artemisiae annuae is poor.
Current wheat field herbicide is limit by crop safety, herbicide spectrum is also limited, it is used alone the generation that a kind of weedicide single dose can not control weeds of wheat completely effectively, moreover some weedicide is due to water-soluble big or the field lasting period is too short, consumption is excessive or dispenser is uneven all easily causes the residual hazard to this season crop or succession crop. Therefore, the present invention selects and can herbicide compose different, it is made into mixture use after the benzene flumetsulam of relative merits complementation and isoproturon two kinds of suitable decrements of weedicide, not only expand herbicide spectrum, significantly improve herbicidal effect, it also avoid and this season crop is produced poisoning and succession crop is produced the possibility of residual hazard.
Summary of the invention
It is an object of the invention to provide a kind of containing the mixed herbicide of benzene flumetsulam and isoproturon.
It is a further object of the present invention to provide the application of this weedicide in wheat paddock weeding.
Containing a mixed herbicide for benzene flumetsulam and isoproturon, this weedicide is taking benzene flumetsulam and isoproturon as principle active component, and the mass ratio of benzene flumetsulam and isoproturon is 1��80:1��80. The mass ratio of preferred benzene flumetsulam and isoproturon is 1��60:1��70, more preferably 1��, 30:30��1, more more preferably 1��12:12��1, the mass ratio of benzene flumetsulam and isoproturon can also be preferably 12:1,6:1,1:1,1:6,1:12,1:9,1:4,1:7,30:1.
In mixed herbicide, both benzene flumetsulam and the isoproturon mass percentage in weedicide is 1��85%, it is preferable that mass percentage is 10��80%, more preferably 30��70%.
In the benzene flumetsulam of the present invention and the binary built preparation of isoproturon, except the effective constituents such as benzene flumetsulam and isoproturon, it is also possible to add on pesticide preparation any one formulation that the auxiliary agents such as the conventional surfactants, toxinicide, thickening material, solvent or the solid packing that allow are mixed with on agricultural chemicals to allow. Preferably it is processed into missible oil, suspension agent, aqueous emulsion, microemulsion, wettable powder, water dispersible granules.
The application of mixed herbicide of the present invention in wheat paddock weeding, especially in the application preventing and kill off gramineous weeds and broadleaf weeds in wheat paddock, there is the advantages such as broad weed-killing spectrum, instant effect, residual poison low, low, safety and environmental protection, it is the wheat crop chemical herbicide of high-quality.
Compared to the prior art, the useful effect of the present invention:
The combinations of herbicides of the present invention, the advantage such as there is broad weed-killing spectrum, instant effect, poison efficient, low, remain low, safety and environmental protection, it is possible to reduce pesticide usage amount, reduce pesticide residue, Environmental compatibility is good, to advantages such as person poultry safeties, be the wheat crop chemical herbicide of high-quality.
1, weeding activity height. The herbicidal composition of the present invention can kill weeds by two kinds of different mechanism so that weeds resistance produces decrease in velocity, and effective ingredient consumption reduces, but drastically increases the removing activity of weedicide.
2, herbicidal spectrum is wide, and the lasting period is long. Benzene flumetsulam is broad spectrum weeding agent, is mainly used in preventing and kill off broadleaf weeds, and isoproturon is mainly used in wheat, barley, cotton, corn, soybean, pea, broad bean, prevents and kill off annual gramineous weed peanut and other crops. After both mixing, it is possible to improve the prevention effect of gramineous weeds and broadleaf weeds.
3, weeds resistance is delayed. Herbicidal composition of the present invention, by binary built, reduces weeds to the resistance of medicament, and improves the anti-effect of antagonism weeds, thus extend the work-ing life of medicament.
4, security height. Owing to the use content of various effective constituent reduces, make medicament under the prerequisite that improve drug effect, reduce pesticide residue, it also avoid and wheat and succession crop security be have also been obtained raising, avoid the possibility that people and animals are produced residual hazard by agricultural chemicals.
