Abstract
The invention discloses a kind of Herbicidal combinations and application thereof containing Mediben and amicarbazone, this Herbicidal combinations is taking Mediben and amicarbazone as main active ingredient, and the mass ratio of Mediben and amicarbazone is 1～60:1～60. Herbicidal combinations of the present invention can be used for corn field postemergence weed control, has remarkable result especially for preventing and kill off broad leaved weed in corn field. Herbicidal combinations of the present invention having improved under the prerequisite of drug effect, delays Weed Resistance with respect to single dose, and herbicidal spectrum is wide, and the lasting period is long, and corn and succession crop are all had to security.
Description
Technical field
The invention belongs to technical field of pesticide, especially herbicide field, the binary that is specifically related to a kind of Mediben and amicarbazone is multipleJoin Herbicidal combinations, this Herbicidal combinations can be applicable to corn field postemergence weed control.
Background technology
Mediben, has another name called wheat straw prestige; Dicamba. The chloro-O-Anisic Acid of chemical name: 3,6-bis-, structural formula is:
Mediben belongs to hormone herbicide. There is interior suction conduction, annual and perennial broadleaf weed are had to remarkable preventive effect.Mediben is sprayed for after seedling, and medicament can, very soon by the leaf of weeds, stem, root absorption, conduct by bast and xylem up and down,Focus mostly at separate living tissue and the vigorous position of metabolic activity, hinder the normal activity of plant hormone, thereby make its death. With rear oneAs 24h broad leaved weed there will be lopsided curling symptom, 15～20d death.
Amicarbazone, chemical name: the 4-amino-5-oxo-3-isopropyl-N-tert-butyl group-1,2,4-triazole-1-formamide, belongs to amino threeAzoles quinoline ketone herbicide, structural formula:
Amicarbazone is inhibitor of photosynthesis, is mainly used in before corn and sugarcane seedling or postemergence weed control, prevent and kill off most ofs dicotyledonous withAnnual monocotyledon weed is as piemarker, lamb's-quarters, Amaranthus weeds, Siberian cocklebur, pharbitis nilChoisy etc.
At present corn field herbicide is limit by crop safety, and herbicide is composed also limited, uses separately a kind of herbicide single dose can not be completeEffectively control the generation of corn field weed, moreover some herbicide due to water-soluble large or the field lasting period is oversize, consumption is excessive orDispenser is inhomogeneous all easily causes the residual hazard to this season crop or succession crop. Therefore, the present invention selects herbicide to compose difference,After two kinds of suitable decrements of herbicide of the Mediben of pluses and minuses complementation and amicarbazone, be made into mixture and use, so both expanded herbicide spectrum,Obviously improve herbicidal effect, also avoided this season to make deposits yields poisoning and the possibility to succession crop generation residual hazard.
Summary of the invention
The object of this invention is to provide a kind of Herbicidal combinations containing Mediben and amicarbazone.
Another object of the present invention is to provide the application of this Herbicidal combinations in cornfield weeding.
Containing a Herbicidal combinations for Mediben and amicarbazone, it is characterized in that this Herbicidal combinations taking Mediben and amicarbazone asMain active ingredient, the mass ratio of Mediben and amicarbazone is 1～60:1～60. The preferably quality of Mediben and amicarbazoneThan being 1～60:1～30, more preferably 29～60:1～5, most preferably are 12～59:1.
In Herbicidal combinations, the two quality percentage composition in Herbicidal combinations of Mediben and amicarbazone is 1～80%, excellentSelecting quality percentage composition is 10～65%, and further preferred mass percentage composition is 30～65%.
In the binary built composition of Mediben of the present invention and amicarbazone, except the active ingredient such as Mediben and amicarbazone,Can also add the auxiliary agents such as the conventional surfactants, thickener, solvent or the solid packing that allow on pesticidal preparations is mixed with on agricultural chemicalsAny one formulation allowing. Preferably be processed into missible oil, suspending agent, aqueous emulsion, microemulsion, water dispersion granule, wettable powderAgent etc.
Herbicidal combinations of the present invention can be applied in corn field postemergence weed control, particularly preventing and kill off grass family and wealthy in corn fieldIn leaf weeds, application has remarkable result.
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 weeds anti-Property produce Speed Reduction, greatly improve the removing activity of herbicide.
2, herbicidal spectrum is wide, and the lasting period is long. Amicarbazone is broad spectrum weeding agent, and it is to annual and perennial broad leaved weedHave good preventive effect, Mediben is the herbicide of preventing and kill off broad leaved weed. Both can improve multiple broad-leaved after mixingThe control of weeds.
3, delay Weed Resistance. Herbicidal combinations of the present invention, by binary built, reduces the resistance of weeds to medicament, and carriesThe preventive effect of high antagonism weeds, thereby the service life of prolongation medicament.
4, safe. Because its using dosage is under control, medicament is being improved under the prerequisite of drug effect, it is to jadeThe security of rice and succession crop is also improved.
Herbicidal combinations of the present invention, is applied to corn field postemergence weed control, and it can prevent and kill off various broad leaved weeds in corn field,Improve under the prerequisite of drug effect, corn and succession crop have all been had to security.
Therefore, Herbicidal combinations of the present invention can be applied in the herbicide for the preparation of corn field postemergence weed control, particularly existsApply for the preparation of preventing and kill off in the herbicide of broad leaved weed in corn field.
