Abstract
The invention discloses a ternary herbicidal composition and application thereof. Effective active components include nicosulfuron as a first active component, topramezone as a second active component and bromoxynil octanoate as a third active component, and the weight ratio of the nicosulfuron to the topramezone to the bromoxynil octanoate is (1 to 99) to (1 to 99) to (1 to 99). The composition can be prepared into agriculturally allowable water-dispersible granules, wettable powder, suspensions and dispersible oil suspensions. The components of the ternary herbicidal composition are reasonable, the herbicidal effect in corn fields is good, moreover, the activity and herbicidal effect are not the simple addition of the activities of all the components, and compared with conventional unitary preparations or binary compound preparations, besides a remarkable herbicidal effect, the ternary herbicidal composition has a remarkable synergistic effect, broadens the weed control spectrum, reduces the prevention and eradication cost, and is highly safe for crops.
Description
Technical field
The present invention relates to a kind of cornfield weeding composition, by active component nicosulfuron, topramezone and decoyl bromobenzene
Nitrile and auxiliary agent composition, belong to technical field of compounded pesticide.
Background technology
Nicosulfuron, English name is nicosulfuron, and chemical name is：2-（4,6- dimethoxypyridin -2- base ammonia
Base formamido group sulphonyl）- N, N- dimethyl nicotinamide.Belong to sulfonamides inner sucting conduction type herbicide after seedling, broad weed-killing spectrum, remove
Grass activity is high, drug action is fast.The mechanism of action is acetolactate synthestase（ALS enzyme）Inhibitor, weeds pass through cauline leaf and root
Portion absorbs, and through bast and xylem conduction, the activity of suppression acetolactate synthestase, leads to branched-chain amino acid biosynthesis block,
And then the synthesis of impact protein, suppress weeds cell division, cause weeds to stop growing, then dead.Can be used for preventing and kill off jade
The rice annual and perennial grassy weed in field and part broad leaved weed, to barnyard grass, lady's-grass, green bristlegrass, Amaranthus retroflexus, purslane etc.
There is preferable preventive effect.
Topramezone, is benzene pyrazoles humulone 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
Green bristlegrass, eleusine indica, lamb's-quarters, knotweed, piemarker, purslane, Siberian cocklebur, black nightshade etc., but undesirable to lady's-grass 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 chloroplaset synthesize under light illumination and function, ultimately result in the serious albefaction of weeds lobus cardiacus, necrosis, weeds are dead
Die.Field test shows, the corn to most types for the topramezone（Conventional field corn, corn, pop corn, viscous
Corn）All show extraordinary security, be 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：The bromo- 4- decoyl oxygen of 3,5- bis-
Benzonitrile.Selective 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 wheat and corn field, can effectively prevent and kill off the broad leaved weeds such as wheat, barley, corn, Europe and
Australia has become as the herbicide of large-tonnage use.
Applicant finds still do not have the group that nicosulfuron, topramezone and bromoxynil octanoate three compound at present through retrieval
Conjugate patent.Simultaneously through long-term test it was unexpectedly observed that by nicosulfurons different for the mechanism of action, topramezone and decoyl
Brominal compounds, and has obvious synergy to barnyard grass, lady's-grass, green bristlegrass, Amaranthus retroflexus, chenopodium glaucum linn, piemarker, pale persicaria etc. and makees
With, significantly improve the prevention effect to corn field grassy weed and broad leaved weed, expand weed control spectrum, reduce cost accounting,
Improve 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 synergistic effect 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）First active component nicosulfuron；
B）Second active component topramezone；
C）3rd active component bromoxynil octanoate.
