Description

A kind of ternary weeding composition and its application
Technical field
The invention belongs to pesticide fields, and in particular to a kind of ternary weeding composition and its application.
Background technique
Not only herbicidal spectrum is relatively narrow, bioactivity is lower for herbicide exclusive use, can also cause the generation of herbicide resistance;It removes Compounding between careless agent both can solve the problem that pesticide single dose toxicity is big, effect is poor, and being used interchangeably between different pesticides It is capable of the generation of retarding action object drug resistance, there is ideal using effect, therefore pesticide between different role mechanism Compounding is current research focus in the field of pesticide.
Isoxaflutole is a kind of organic heterocyclic class selectivity internal-suction type herbicide before seedling stage, is mainly absorbed via weeds young root Conduction inhibits p-hydroxyphenypyruvate dioxydenase activity.It can be widely used for corn, sugarcane, cotton, potato, ornamental plant Equal crops, to prevent and kill off piemarker, Chenopodiaceae, summer cypress, salsola collina, black nightshade, Amaranthus retroflexus, willow leaf, thorn knotweed, beggar-ticks, purslane, herba stellariae mediae, A variety of annual broadleaf weeds such as elscholtiza, Siberian cocklebur, acalypha copperleaf, water spine pin, pale persicaria, Veronica and herba digitariae, barnyard grass, Cowhells Some annual gramineous weeds such as grass, semen euphorbiae, faber bristlegrass herb and herba setariae viridis.
Halosulfuronmethyl is a kind of sulfonylurea herbicide, can be used for wheat, corn, rice, sorghum, cotton, sugarcane, grass Prevent and kill off broadleaf weeds and sedge weed in level ground etc..But it is poor to grassy weed effects such as barnyard grass, semen euphorbiaes.
Atrazine is triazine selective herbicide, is mainly absorbed with plant root and is transmitted to separate living tissue and leaf Face, by inhibiting the electron transmission in photosynthesis of plant to keep weeds lethal.It is mainly used for preventing and kill off corn, sorghum, sugarcane, tea Garden, orchard and rubber plantation field annual gramineous weed and broadleaf weeds, it is very safe to corn.
Do not have in the prior art Jiang the relevant report of isoxaflutole, halosulfuronmethyl and atrazine.
Summary of the invention
The purpose of the present invention is to provide a kind of component is reasonable, drug cost is low, is not likely to produce the herbicide group of drug resistance Close object, to gramineae weed, broadleaf weeds and nutgrass flatsedge have preferable control efficiency, to slow down Weed Resistance, reduce drug Dosage etc. has positive effect.
The present invention provides following technical scheme
A kind of ternary weeding composition, active constituent are made of component A, component B and component C;Component A Wei isoxazole grass Ketone, component B are halosulfuronmethyl, and component C is atrazine;The weight proportion of the component A, component B and component C are 2-40:1- 20:10-120。
Ternary weeding composition of the present invention, it is characterised in that:The weight of the component A, component B and component C are matched Than for 2-20:1-10:10-100;The weight proportion of the preferably described component A, component B and component C are 1:1:12.
Ternary weeding composition of the present invention, the total weight hundred of the component A, component B and component C in the composition Dividing content is 5-85%.
Ternary weeding composition of the present invention, the total weight hundred of the component A, component B and component C in the composition Dividing content is 20-70%.
Ternary weeding composition of the present invention is used to prevent and kill off the purposes of farmland weed.Such as corn field, sugarcane field, Wheat paddock, paddy field, sorghum field, Cotton Fields, lawn etc..
Purposes of the present invention, the preferred weeds are preferably gramineae weed, broadleaf weeds and nutgrass flatsedge.Institute State weeds include barnyard grass, semen euphorbiae, Monochoria vaginalis, the rhizome of nutgrass flatsedge, herba digitariae, herba setariae viridis, herba eleusines indicae, herba stellariae mediae, Siberian cocklebur, Drilgrass, nutgrass flatsedge, Clearvers etc..
The present composition can be prepared into adaptation dosage form, preferred dosage form wettable powder with agriculturally acceptable auxiliary combination Agent, missible oil, suspending agent, oil-suspending agent, microemulsion, aqueous emulsion, suspended emulsion, water dispersible granules etc..Auxiliary agent of the present invention Include emulsifier, dispersing agent, wetting agent, binder, disintegrating agent, thickener, stabilizer, antifreezing agent, defoaming agent filler etc..
The preferred dispersing agent is selected from polycarboxylate, lignosulfonates, the phonetic formaldehyde condensation of alkylphenol-polyethenoxy Object sulfate, alkyl benzene sulfonate calcium salt, naphthalene sulfonic acid-formaldehyde condensation product sodium salt, alkyl phenol polyoxyethylene ether, aliphatic acid polyethenoxy Ester, ester polyoxyethylene are one of phonetic or a variety of.
The preferred wetting agent is selected from:Lauryl sodium sulfate, neopelex, Nekal BX, wetting One of bleeding agent F, spaonin powder, silkworm excrement, spaonin powder are a variety of.
The preferred disintegrating agent is selected from:One of bentonite, urea, ammonium sulfate, aluminium chloride are a variety of.
The preferred binder is selected from:Arabic gum, white dextrin, methylcellulose, sodium acrylate, polyvinyl pyrrole One of alkanone, crosslinked polyvinylpyrrolidone, polyethylene glycol, polyvinyl alcohol are a variety of.
The preferred antifreeze is selected from:One of ethylene glycol, propylene glycol, glycerine, polyethylene glycol are a variety of.
The preferred defoaming agent is selected from:Silicone oil, silicone compound, C10-20 saturated fat acid compounds, C8- One of 10 fatty alcohols compounds are a variety of.
