Description
Technical field
The present invention relates to technical field of pesticide, particularly relate to herbicide.
Background technology
Along with the fast development of science and technology, chemical weed control, as a modernization practical technique, is sent out in weed control
Wave huge. effect.Although the development time of Application of Herbicides is the longest, but development speed is very fast.Along with Chinese agriculture is existing
The development of generationization and the progressively transfer of agricultural workforce, cultivation tillage method trends towards scale and intensive, the need to pesticide
The amount of asking dramatically increases.Wherein, herbicide rate of increase in recent years is far above insecticide and antibacterial level of development, accounts for pesticide
The 1/3 of yield proportion.
At present, herbicide of a great variety, it is divided into stem and leaf inorganic agent and closed soil treatment agent according to using method, according to
Its model of action is divided into selectivity and natural disposition two class of going out;It is divided into contact killing type herbicide and conduction according to the conductivity in plant
Pad herbicide；It is divided into sulfonephthalein amine herbicide and Fructus Mali pumilae acid herbicides etc. according to chemical composition.But, the group of the old weeds of agriculture
The composition that falls is diversified, and along with the kind of the different growing weeds of crop also changes.Although for farmland
The needing of chemical weed control has been developed over substantial amounts of herbicide kind for producing upper selection.But, every kind of herbicide has specific
The weeds kind prevented and treated, lack the most very much the herbicide product of crop all weeds in the time of infertility can prevented and treated selectively
Kind, meanwhile, the herbicide kind that life-time service is single, may result in weeds and produce resistance or cause the change of weeds kind, weeds
The rapid replacement of population, substantially increases the difficulty of farmland chemical weed control, while exploitation novel herbicide, two kinds or two
Plant above being used in mixed way of herbicide kind also to arise at the historic moment.
The mixed of herbicide has many advantages: 1, can expand weed control spectrum；2, herbicide is reduced in crop with soil
Residual；3, avoid poisoning, improve the safety to crop；4, reduce cost, increase economic efficiency and save labour；5, extend
The service life of herbicide；6, Herbicide-resistant weeds is effectively prevented and treated；7, herbicide mixture can reduce the kind consumption of lasting period length, because of
And can reduce and remain in soil, prevent the poisoning to late stubble sensitive crop, reduce the pollution to environment.
Different herbicide kinds are different in terms of controlling object, action characteristic, so should be according to the kind of crop, field
Weeds occur, are distributed and the specificity of group, select suitable herbicide kind.It addition, the residual shadow that herbicide is in soil
Ring to the lasting effect of herbicide and the safety to environment.From the standpoint of management of weeds, herbicide should have certain
Residual period, residual period, is the shortest, and herbicidal effect is bad, but residual period is oversize, can cause again under recommend the poisoning of crop.But from ring
Border angle considers, the residual period of herbicide is the shortest more good, and herbicide is the most stable, the most degradable, and residual quantity is big in the environment, can lead
Cause environmental pollution.
Summary of the invention
The technical problem to be solved is to provide a kind of herbicide, and it is the best to the eradicating efficacy of weeds, peace
Entirely, efficiently, and drug degradation is effective, and residual is few.
For solving above-mentioned technical problem, a kind of herbicide, including effective active component, surfactant, dibutyl naphthalene sulphur
Acid sodium, cosolvent ethanol, water, Polyethylene Glycol and Butacide；
Described effective active composition includes flampropmethyl, dichloro quinolinic acid and bensulfuron-methyl；
Described surfactant is OPEO sulfonate.
Further, the weight proportion of described effective active composition is flampropmethyl, dichloro quinolinic acid and bensulfuron-methyl 25
～35:40～50:5～15.
Further, the preparation method of described OPEO sulfonate includes:
The first step, the chlorination of OPEO；OPEO and pyridine are mixed to join reaction
In container, dripping thionyl chloride under the conditions of water bath with thermostatic control, stirring reaction 2h at 80 DEG C, synthesis obtains chloro octyl phenol polyoxy
Vinyl Ether；
Second step, the sulfonation of the OPEO after chlorination；The chloro OPEO taking acquisition adds
Entering in water, chloro OPEO is 1:1.5 with the mass ratio of water, is subsequently added sulfonating agent sodium sulfite, is placed in
In autoclave, under intense agitation when 150 DEG C react 8h, obtain faint yellow dope, with volume ratio be 2: 1 different
The mixture of the third alcohol and water dissolves thick product, then with petroleum ether extraction, removes unreacted raw material and other oil soluble impurity,
Separate lower floor's decompression distillation, vacuum drying, obtain yellow paste dope；
Further, in described weeding herbicide the weight portion of each raw material be respectively effective active composition 80-100 weight portion,
Above-mentioned surfactant 10 weight portion～22 weight portions, nekal 200 weight portion～320 weight portions, cosolvent second
Alcohol 90 weight portion～200 weight portions, water 500 weight portion～1200 weight portions, Polyethylene Glycol 30 weight portion～60 weight portions and
Butacide 20 weight portion～45 weight portions present invention also offers the preparation method of above-mentioned herbicide, are specially than water
Material composition is put in reactor by weight, stirs and is completely dissolved, and is slowly added to water, continues mix and blend 2h, obtains
Obtain herbicide.
The present invention provides a kind of herbicide, and it is the best to the eradicating efficacy of weeds, safety, efficiently, and drug degradation effect
The best, residual is few.
Flampropmethyl of the present invention has effect of well preventing and kill off to weeds, and dosage uses few, high to crop safety；With
Dichloro quinolinic acid, bensulfuron-methyl coordinate can preferably remove the weeds in Herba Imperatae growth course, and the degraded effect in soil
Fruit is good.
Detailed description of the invention
Below in conjunction with embodiment invention estimated and further illustrate
