Description
Technical field
The present invention relates to composition pesticide technical field, especially a kind of corn field herbicide composition.
Background technique
Corn field main weeds have: herba digitariae, Amaranthus retroflexus, setaria glauca, Chloris virgata, herba eragrostidis pilosae, black nightshade, barnyard grass, prince's-feather,
Small Chenopodiaceae, chenopodium glaucum linn, purslane, concave head amaranth, salsola collina, summer cypress, perverse amaranth, herba setariae viridis, numerous fringe amaranth, three-coloured amaranth, Chenopodiaceae, green amaranth, herba eleusines indicae,
The weeds such as feather cockscomb, thorn Chenopodiaceae, iron amaranth, piemarker, flowerofanhour root or herb, axillary flower amaranth.Perennial weeds has japanese bearbind, reed, rhizome of nutgrass flatsedge etc..
The herbicide used after country's corn field seedling at present mainly has: nicosulfuron, rimsulfuron, mesotrione, wheat straw
Fear, thifensulfuron methyl, Brominal etc., mixture preparation have nicosulfuron and atrazine, dicamba and atrazine, nicosulfuron and metribuzin
Deng, but these herbicides still cannot completely effectively prevent and kill off some malignant weeds, such as the rhizome of nutgrass flatsedge, dayflower, piemarker.Study table
Bright, corn field herbicide nicosulfuron, rimsulfuron are lower to corn, waxy corn safety, or even to some general plantings
Kind can also generate more serious phytotoxicity.Therefore, from the aspect of from weed control and to corn safety two, China's corn field
Herbicide after seedling system is still not perfect, and is needed to find other herbicides and is supplemented.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, that the present invention provides a kind of herbicidal effects is good, to corn and glutinous jade
The highly-safe corn field herbicide composition of rice.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of corn field herbicide composition, the active constituent of the herbicide are benzobicylon and rimsulfuron, bicyclic sulphur
The mass ratio of humulone and rimsulfuron is 1-8:2-7.
Further, the mass ratio of the benzobicylon and rimsulfuron are as follows: 1:3,1:5,1:7,3:2,3:5,5:3,
6:7。
Further, the dosage form of the herbicide be wettable powder, it is water dispersible granules, aqueous suspension agent, oil-suspending agent, micro-
One of emulsion, suspended emulsion or aqueous emulsion.Wettable powder, water dispersible granules, aqueous suspension agent, oil-suspending agent, microemulsion,
Suspended emulsion or aqueous emulsion are existing known technology, and preferably wettable powder, water dispersible granules, aqueous suspension agent or oil suspend
Agent.Auxiliary material in above-mentioned dosage form be selected from wetting agent, dispersing agent, stabilizer, thickener, antifreezing agent, suspension stabilizer, defoaming agent,
Preservative, disintegrating agent, solvent, filler etc..
Wetting agent is alkyl sulfate, sulfonate, fatty acid or aliphatic ester sulfate, carboxylic acid soaps, phosphate, polyoxy
Vinyl alkyl phenolic ether, polyoxyethylene aliphatic alcohol ether, any one in polyoxyethylene polyoxypropylene block copolymer can improve
The moisture dispersibility of herbicide in water.
Dispersing agent is barium stearate, alkyl benzene sulphonate sodium salt, alkyl phenol polyoxyethylene ether phosphate, glycerine fatty acid rouge are poly-
Any one in ethylene oxide ether, polyoxyethylene carboxylate, can promote herbicide to disperse in water, have herbicide good
Good stability.
Stabilizer is one or more of epoxidized soybean oil or epoxidized linseed oil.
Thickener is aluminium-magnesium silicate, in hydroxyethyl cellulose, methylcellulose, bentonite, attapulgite, Arabic gum
Any one, the viscosity of adjustable suspending agent improves suspending agent to reduce the sedimentation that suspending agent generates during storage
Suspension stability.
Antifreezing agent is acid phosphate amine salt, in alkylamine, fatty acid amide, organic acid esters, alkyl succinimide
It is one or more of.
Suspension stabilizer is one of aluminum magnesium silicate or precipitated calcium carbonate.
Defoaming agent is silicone emulsion, the fatty acid ester compounded object of higher alcohols, polyoxyethylene polyoxypropylene pentaerythrite ether, polyoxy
Appointing in ethylene polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether and polyoxyethylene polyoxypropylene glycerin ether, dimethyl silicone polymer
It anticipates one kind, plays emulsion adjuvant, so that emulsifying effectiveness is more preferable.
Preservative is benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, calcium propionate.One of
Disintegrating agent is potato starch, sodium carboxymethyl starch, starch, any one in ammonium sulfate, can accelerate water-dispersible grain
The disintegration rate of agent in water, makes water dispersible granules more rapid and better play a role.
Solvent is methyl oleate, methyl esterification soybean oil, corn oil, any one in white oil, can adsorb and remove well
Effective component in careless agent, reaches slow release effect.
Filler is montmorillonite, talcum powder, white carbon black, silica, any one in precipitated calcium carbonate, can be well
The effective component in herbicide is adsorbed, slow release effect is reached.
Further, the active constituent accounts for the 2%-90% of the total weight of herbicide.
Further, the active constituent accounts for the 25%-65% of the total weight of herbicide.
A kind of corn field herbicide composition is preventing and kill off the application in corn field annual grassy weeds.
It is using the beneficial effect of technical solution of the present invention:
To for trying weeds barnyard grass, herba digitariae, herba setariae viridis, piemarker, anti-branch after benzobicylon and rimsulfuron are compounded in the present invention
The activity of weeding of amaranth is above activity when benzobicylon and rimsulfuron is used alone, and has synergistic effect.After another compounding
Degrass spectrum is expanded, and dosage is also reduced.
It is compounded in the present invention using benzobicylon and rimsulfuron, the combination of two kinds of effective component is expanded and killed
Grass spectrum, not only sealed but also killed, and a drug can be effectively controlled Weed infestation in corn entire breeding time, can make up for it single dose and uses defect
And limitation.
