Abstract
The invention discloses a ternary weeding composition and application thereof. The ternary weeding composition comprises three effective active ingredients which refer to foramsulfuron, topramezone and bromoxynil octanoate in sequence, wherein the mass ratio of the foramsulfuron to the topramezone to the bromoxynil octanoate is (1-90): (1-90): (1-90). The ternary weeding composition can be prepared into agriculturally permissible water dispersible granules, wettable powder, suspending agents and dispersible oil suspended agents. Compared with existing single preparations or binary compound preparations, the ternary weeding composition has the advantages that the ternary weeding composition is reasonable in ingredients and remarkable in weeding effect in corn fields; with the activity and the weeding effect which are obtained not through simple superposition of the activity of each ingredient, the ternary weeding composition is remarkable in synergism, enlarged in weeding spectrum, lower in prevention and weeding costs and capable of ensuring safety of crops.
Description
Technical field
The present invention relates to a kind of cornfield weeding composition, by active component formamido group Sulfometuron Methyl, topramezone and pungent
Acylbromide cyanophenyl and auxiliary agent composition, belong to technical field of compounded pesticide.
Background technology
Formamido group Sulfometuron Methyl, English name is foramsulfuron, and chemical name is: n, n- dimethyl -2- [3- (4,
6- dimethoxypyridin -2- base) ureido sulfuryl] -4- formoxyl amido benzamide.It is a kind of sulfonylurea herbicide,
The important grassy weed of many and the broad leaved weed in world Major Maize producing region can be prevented and kill off, to rear stubble rotation crop and environment
All very safe.But poor to the preventive effect of part grassy weed and broad leaved weed, the weeds such as Herba Digitariae, Herba Setariae Viridis, Herba chenopodii grass age relatively
Hour, prevention effect is good, but when careless age is larger, even if increasing using dosage, nor management of weeds well.
Topramezone, is benzene pyrazoles oxadiazon again, and English name is topramezone, and chemical name is: [3- (4,5- bis-
Hydrogen -3- isoxazolyl) -4- sulfonyloxy methyl -2- methylbenzene] 5- hydroxyl -1- methyl isophthalic acid h- pyrazoles -4- base) ketone.Pyrazoline ketone
Herbicide, broad weed-killing spectrum, there is preventive effect to corn field overwhelming majority grassy weed and broad leaved weed, can effectively prevent and kill off
Herba Setariae Viridis, Herba Eleusines Indicae, Herba chenopodii, knotweed, Herba Abutili, Herba Portulacae, Herba Xanthii, Herba Solani Nigri etc., but undesirable to Herba Digitariae and barnyard grass preventive effect.Topramezone
Can be absorbed by the blade of weeds, root and stem, and Bidirectional Conduction up and down in plant, remote-effects carotenoid
Synthesis, interference chloroplast synthesize under light illumination and function, ultimately result in the serious albefaction of weeds lobus cardiacus, tissue necrosiss, weeds are dead
Die.Field test shows, topramezone is (conventional field corn, sweet corn, pop corn, viscous to the Semen Maydiss of most types
Semen Maydiss) all show extraordinary safety, it is the safest in all after-seedling herbicide for maize kinds both at home and abroad in the market
Herbicide.Topramezone is also the fastest herbicide after seedling of herbicide in the market, and at 20 DEG C, spray 2～4 days can
To take effect, albefaction poisoning symptom in weeds above-ground plant parts.
Bromoxynil octanoate, English name bromoxynil octanonate, chemical name is: 3,5- bis- bromo- 4- decoyl oxygen
Benzonitrile.Selectivity after seedling cauline leaf process contact killing type herbicide, is mainly absorbed by blade, carries out extremely limited biography in plant body
Lead, by each process of inhibited photosynthesis, including suppression photophosphorylation reaction and electron transmission, particularly photosynthesis
Hill reaction, make plant tissue downright bad rapidly, thus reaching herbicide purpose, when temperature is higher, speeding-up blade is withered.In China
Be widely used in management of weeds in Semen Tritici aestivi and corn field, can effectively prevent and kill off the broad leaved weeds such as Semen Tritici aestivi, Fructus Hordei Vulgaris, Semen Maydiss, Europe and
Australia has become as the herbicide of large-tonnage use.
Applicant finds through retrieval, does not still have formamido group Sulfometuron Methyl, topramezone and bromoxynil octanoate three multiple at present
The compositionss patent joined.Simultaneously through long-term test it was unexpectedly observed that by formamido group Sulfometuron Methyls different for the mechanism of action, benzene
Azoles humulone and bromoxynil octanoate compound, and barnyard grass, Herba Digitariae, Herba Setariae Viridis, Amaranthus retroflexus, chenopodium glaucum linn, Herba Abutili, pale persicaria etc. are had bright
Aobvious potentiation, significantly improves the prevention effect to corn field grassy weed and broad leaved weed, expands weed control spectrum, reduces
Cost accounting, improves to crop safety.
Content of the invention
It is an object of the invention to provide a kind of component is rationally, drug cost is low, and potentiation is notable, and herbicidal effect is good,
Preventing and treating spectrum is wide, the ternary weeding composition to crop safety.
Another object of the present invention is to providing above-mentioned ternary weeding composition preparation formulation.
It is still another object of the present invention to provide above-mentioned composition is on preventing and treating corn field grassy weed and broad leaved weed
Application.
For the defect overcoming existing unitary agent or two-spot to compound, the technical scheme of Herbicidal combinations of the present invention is so
Solve:
A) the first active component formamido group Sulfometuron Methyl；
B) the second active component topramezone；
C) the 3rd active component bromoxynil octanoate.
