Abstract
The invention discloses herbicide special for a cotton field. The herbicide is formed by mixing quizalofop-p-ethyl, halosulfuron-methyl and garlic oil. The herbicide has a better killing effect on gramineous weeds, cyperaceae weeds and broadleaf weeds, and drug harm to crops is relieved.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, especially a kind of Cotton Fields herbicides special, belongs to field of agricultural production technologies.
Background technology
Cotton is the important economic crops of China.Cotton in China is widely distributed, has plantation from south to north, and total sowing area of Cotton in China is 75,000,000 mu of left and right.The principal element that affects output of cotton is insect pest and crop smothering.The conventional weed killer herbicide of Cotton Fields has at present: trefanocide, Acetochlor etc.Trefanocide belongs to long residual effect weed killer herbicide, easily causes the poisoning of rear stubble, and must mixed soil while using, and time-consuming work consuming, also can cause that with rear cotton knee is large; Acetochlor herbicide spectrum is narrow, and the lasting period is short, and soil moisture content is had relatively high expectations.Due to the use in a large number for years of cotton field weed killer herbicide, its drug injury problem also manifests day by day simultaneously.
Quizalotop-ethyl, chemical name: (R)-2-[4-(6-chloroquinoxalin-2-yloxy) phenoxy group] ethyl propionate, molecular formula: C

Garlic oil is the material extracting from garlic, and main component is pi-allyl propyl disulfide compound, diallyl disulfide, diallyl trisulfide, allicin etc.There is sterilization and the anthelmintic action of wide spectrum.
Summary of the invention
The invention provides a kind of Cotton Fields herbicides special, this weed killer herbicide forms by Quizalotop-ethyl, halosulfuronmethyl and garlic oil are composite, not only grassy weed, sedge weed and broad-leaved section weeds is had to good killing action, and has alleviated chemical injury of crops.
Technical scheme of the present invention is: a kind of Cotton Fields herbicides special, it is characterized in that, comprise active ingredient and auxiliary agent, wherein active ingredient forms by Quizalotop-ethyl, halosulfuronmethyl and garlic oil are composite, wherein the mass ratio of Quizalotop-ethyl, halosulfuronmethyl and garlic oil is 10:2-3:1-2, and the content of described active ingredient is 5-65wt%.
Preferably, the mass ratio of described Quizalotop-ethyl, halosulfuronmethyl and garlic oil is 10:2.5:1.5.
Preferably, the content of described active ingredient is 14wt%.
Weed killer herbicide of the present invention can be prepared into the preparations such as aqueous emulsion, suspension emulsion, wetting powder, microemulsion.
Method for producing aqueous emulsion is: Quizalotop-ethyl, garlic oil, No. 150 industrial solvents, agricultural emulsifier NO．600 and agriculture breast NP-10 are mixed, make it to be dissolved into even oil phase; Halosulfuronmethyl, polyvinyl alcohol and propane diols are added to the water and are mixed, form even water; Under high-speed stirred, water is joined in oil phase, form the aqueous emulsion of favorable dispersibility.
Suspension emulsion preparation method is: Quizalotop-ethyl, garlic oil, No. 150 industrial solvents, No. 500, agriculture breast and Nongru-700s number are mixed, make it to be dissolved into even oil phase; Halosulfuronmethyl, polyvinyl alcohol, dodecyl sodium sulfate, organic silicone and water mixing frosted are made into aqueous suspension agent; Then the oil phase preparing and aqueous suspension agent shearing are uniformly dispersed, make suspension emulsion.
Using method: this product should, after cotton seedling, in annual gramineous weed 3-5 leaf phase dispenser, be noted to the spraying of weeds cauline leaf evenly.Strong wind sky or estimate rainfall in 1 hour, please don't dispenser.
The invention has the beneficial effects as follows:
(1) broad weed-killing spectrum of the present invention, not only grassy weed is had to good preventive effect, broad-leaved section weeds (as Amaranthus retroflexus, kitchen garden, acalypha copperleaf, field thistle etc.) and sedge weed (as the rhizome of nutgrass flatsedge) etc. are also had to good preventive effect simultaneously.
(2) the present invention, by after composite to Quizalotop-ethyl, halosulfuronmethyl and garlic oil, plays synergistic function, and herbicide effect obviously improves; Especially adding of garlic oil, its synergistic effect is obvious.
(3) the present invention, by having reduced the usage amount of Quizalotop-ethyl and halosulfuronmethyl after composite, passes through the composite of three simultaneously, has reduced key.Alleviated the resistance problem of weed in cotton field to conventional herbicide simultaneously.
(4) garlic oil of the present invention also has certain sterilization, anthelmintic action, and cotton disease is had to certain prevention effect.
