Stork grass etc..
Wheatland and milpa are typically all large-scale plantation, and artificial weeding is unrealistic, and traditional herbicide herbicidal spectrum is narrow,
The weeds of corn field and weeds field cannot be used simultaneously, and herbicidal effect is poor, it is big to crop damage.
Summary of the invention
In view of the above-mentioned problems existing in the prior art, the present invention provides that a kind of herbicidal effect is good, herbicidal spectrum is wide, wheat paddock and
The corn field herbicide containing halosulfuronmethyl applicable simultaneously.
In order to solve the above technical problems, The technical solution adopted by the invention is as follows:
A kind of herbicide containing halosulfuronmethyl, the active constituent of the herbicide are halosulfuronmethyl and methyl iodide sulphur
Grand, halosulfuronmethyl and the grand mass ratio of methyl iodide sulphur are (2-5): (3-15).
Further, the halosulfuronmethyl and the grand mass ratio of methyl iodide sulphur are 2:3,2:5,3:7,3:10 or 5:12.
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 moisture
The disintegration rate of shot 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 20%-60% of the total weight of herbicide.
Application of the herbicide containing halosulfuronmethyl in wheat, maize seed gramineae weed and broadleaf weeds.
Herbicide uses after wheat, corn seeding before seedling or before 3 leaf phases.
It is using the beneficial effect of technical solution of the present invention:
List is above to the activity of weeding of broadleaved herb, Cyperaceae after halosulfuronmethyl and the grand compounding of methyl iodide sulphur in the present invention
Activity when halosulfuronmethyl and grand methyl iodide sulphur is solely used, there is synergistic effect.Degrass spectrum is expanded after another compounding, is made
It is also reduced with dosage.
In the present invention after halosulfuronmethyl and the grand compounding of methyl iodide sulphur, synergistic effect is shown within a certain ratio range,
The control efficiency of composition is significantly improved than single dose, reduces the dosage of pesticide, reduces Pesticide use number, drop
Low drug cost, reduces pesticide to the adverse effect of ecological environment, is conducive to keep ecological balance.
