Abstract
The herbicide consists of quiazalofop-P-ethyl 10.1-30.0 wt%, emulsifier 26-40 wt% and synergist 1.0-10.0 wt% as well as solvent in the rest amount. It has relatively higher quizalofop-P-ethyl content and thus high graminaceous weed killing effect. In addition, it is suitable for use in low temperature and drought weather conditions and is erosion resistant.
Description
Technical field
The present invention relates to a kind of weed killer herbicide, be specially the agent of a kind of killing graminaceous weed in latifolious crop field Quizalotop-ethyl herbicide, be a kind of Quizalotop-ethyl missible oil.
Background technology
The Quizalotop-ethyl herbicide agent has obtained applying widely with its unique advantage, but existing Quizalotop-ethyl herbicide agent, the content of its Quizalotop-ethyl lower (below 5%), a little less than the drug effect, can not be used for elder weed (5-7 leaf phase), responding time is long, and using dosage is big, the use cost height, result of use is poor, and especially under low temperature, dry climate condition, drug effect reduces obviously, and the resistance of rainwater washing against poor performance has directly influenced its application performance.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of Quizalotop-ethyl content higher herbicide for killing graminaceous weed in latifolious crop field, strong drug action, can be used for elder weed, responding time is short, and using dosage is little, and use cost is low, result of use is good, the suitable low temperature of energy, dry climate condition, and the resistance of rainwater washing against performance is good, and application performance is good.
Herbicide for killing graminaceous weed in latifolious crop field of the present invention adds emulsifier, synergist and solvent by Quizalotop-ethyl and makes, and wherein the weight content of Quizalotop-ethyl is 10.1～30.0%.
Usually the weight of batching consists of:
10.1 Quizalotop-ethyl raw material consumption, emulsifier 26～40%, synergist 1.0～10.0%, surplus that～30.0% Quizalotop-ethyl is converted to are solvent.
Optimum weight consists of:
10.5 Quizalotop-ethyl raw material consumption, emulsifier 26～35%, synergist 2.0～5.0%, surplus that～20.0% Quizalotop-ethyl is converted to are solvent.
Wherein:
The chemical name of Quizalotop-ethyl is (R)-2-[4-(6-chloro-quinoxaline-Z-base oxygen) phenoxy group] ethyl propionate, chemical constitution is:
In the practice, the effective body of Quizalotop-ethyl adds with the form of former powder of Quizalotop-ethyl or Quizalotop-ethyl mother liquor.The effective body burden of Quizalotop-ethyl 〉=90% in the former powder of Quizalotop-ethyl, the effective body burden of Quizalotop-ethyl 〉=40% in the Quizalotop-ethyl mother liquor.
Solvent for use, synergist, emulsifier are commercially available industrial goods among the present invention.
Solvent for use is one or more the arbitrary proportion combination in aromatic hydrocarbons, aliphatic hydrocarbon, alicyclic, alcohol, ketone, ether, vegetable oil, halogenated alkane, dimethyl formamide, methyl-sulfoxide, acetonitrile, the chlorobenzene, mixed solvent with the strong methyl alcohol of dissolving power, chloroform, dimethyl formamide, acetone etc. and compositions such as benzene,toluene,xylene is good, is easy to obtain the product of premium properties.
Wherein:
Aromatic hydrocarbons has: benzene,toluene,xylene, naphthalene, Fluhyzon, arylhydrocarbon in diesel oil etc.
Aliphatic hydrocarbon, alicyclic have: white gas, diesel oil, white oil, machine oil, diesel oil etc.
Alcohol has: methyl alcohol, ethanol, propyl alcohol, isopropyl alcohol, butanols, isobutanol, glycerine, ethylene glycol etc.
Ketone has: cyclohexanone, MEK, acetone, isophorone; Ether is: glycol ether, propylene glycol etc.
Vegetable oil has: rapeseed oil, cotton seed oil, turpentine wet goods.
Halogenated alkane has: carrene, chloroform, trichloroethanes, carbon tetrachloride etc.
Used synergist, emulsifier are conventional synergist, emulsifier, as synergist azone, JSE-1, JSE-2 etc. are arranged, and emulsifier has 8227# emulsifier, 8220# emulsifier etc.
The preparation method of weed killer herbicide of the present invention and conventional preparation method are similar, carry out in two steps:
(1) dissolving: with a part of solvent suction heat automatically mixing kettle (band high-speed shearing machine, can in whipping process, heat up automatically, high-speed stirred also is beneficial to emulsifying effectiveness) in, take by weighing and obtain Quizalotop-ethyl former powder of the needed Quizalotop-ethyl of effective content missible oil or Quizalotop-ethyl mother liquor input mixing kettle.Start clipper and stirred 20～30 minutes, fluid temperature reaches 40～50 ℃ in the still, and Quizalotop-ethyl stops when all dissolving stirring.
(2) emulsification: add the solvent of synergist, emulsifier and surplus in mixing kettle, stirred 30～50 minutes, temperature in the kettle reaches 60～70 ℃, and sampling detects and obtains product.
Weed killer herbicide product of the present invention is light yellow homogeneous liquid, does not have visible missible oil and precipitation.
Weed killer herbicide of the present invention is applicable to farmlands such as most of broad leaf crops, vegetables, fruit tree, Chinese medicine, and applicable crops has:
[1] Cruciferae: rape, Chinese cabbage, cauliflower, radish etc.;
[2] pulse family: soybean, peanut, mung bean, red bean, broad bean, pea, Kidney bean, clover etc.;
[3] Solanaceae: tomato, capsicum, potato, eggplant etc.;
[4] Curcurbitaceae: watermelon, muskmelon, pumpkin, sponge gourd, tobacco etc.;
[5] Liliaceae: shallot, garlic, leek, day lily etc.;
[6] Umbelliferae: carrot, caraway, fennel, celery etc.;
[7] Chinese medicine class: safflower, the Radix Astragali, red butch clover, isatis root, Radix Glycyrrhizae, matrimony vine etc.;
[8] fruit tree: citrus, apple, pears, pineapple, bamboo grows, grape, pepper, tea place, mulberry field etc.;
[9] cotton, peppermint, lettuce, Chinese yam, flax, konjaku etc.
Herbicidal spectrum: annual and perennial grassy weeds such as lady's-grass, wild oat, barnyard grass grass, green foxtail, setaria glauca, Ye Li, eleusine indica, amur foxtail, india lovegrass, moleplant seed, bromegrass, lolium temulentum, millet genus, annual bluegrass, Paspalum distichum, Bermuda grass, cogongrass, quackgrass, reed.
Use age and method:
Before the 4 leaf phases of weeds during high humidity with low amount, 4 leaf phases leaf phase to 5 with in amount, as weeds 6 leaves more than the phase, weather arid, low temperature, then consumption height.Method: first dilute with water, the cauline leaf spraying is handled again.
Use in most of broad leaf crops, vegetables, fruit tree, Chinese medicine field, dosage is few, in the spraying of weeds 3-7 leaf phase cauline leaf, most of grassy weeds is had excellent preventive effect, weeds flavescence in 2 days, cauline leaf necrosis in 3-4 days, the death of 6-9 leaf weeds.
The advantage of weed killer herbicide of the present invention:
1, active constituent content brings up to 10.1～30%, strong drug action, and using dosage is little, and use cost is low, and result of use is good, can be used for elder weed, and responding time is short.Evidence is compared with original like product operating position, and every mu of consumption reduces more than 65%, and drug effect improves more than 15%, responding time 1～2 day in advance; For elder weed (5-7 leaf phase), drug effect is obvious, and the like product optimum period wide ranges than original can have more the 1-2 leaf phase; And low temperature, arid climatic conditions are to the drug effect influence not quite.
2, the resistance of rainwater washing against performance is good, executes to rain in back 1 hour, and drug effect is not had influence, reduces 1 hour than like product, improves application performance greatly.
3, active constituent content brings up to 10.1～30%, has reduced solvent load (most of solvent, as: benzene, dimethylbenzene etc. have pollution to environment), thereby has reduced the environmental pollution to the crop farmland.
4, product design is big, saves packing, is convenient to transportation.
