Description
Technical field
The present invention relates to a kind of acaricide of technical field of pesticide, in particular it relates to a kind of ethyl oleate acaricide and oil
The new application of acetoacetic ester.
Background technology
Phytophagous mites is found on the crops all over the world, it has, and small volume, breeding be fast, strong adaptability with
And the features such as be also easy to produce the resistance to the action of a drug, be it is generally acknowledged be difficult preventing and treating pest communities.It is used on the pesticide market of China at present
The most dependence on import of acaricide, the acaricidal expense of import accounts for the 88.8% of general import agricultural chemicals expense.And mite class is to crop
The loss caused, has obvious increase in Past 30 Years.Main cause is intensive monoculture and killed using non-specific
Worm agent.Secondly because the growth time of one generation of mite class is shorter, resistance can be produced to original acaricide rapidly.These desinsections
Often acaricidal activity is not high for agent, and mite class natural enemy has also been eliminated while mite class is killed.At present, the 3R problems of chemical pesticide are
Residual (Residue), resistance (Resistance) and pest resurgence (Resurgence) are generally paid close attention to by people, the mankind
Understanding to agricultural chemicals is also more and more deep, and the use of agricultural chemicals is not focused on killing off the insect pests, but more focuses on regulation.Therefore, use
Obligate acaricide turns into the major measure of preventing and treating phytophagous mites, and acaricidal development is inevitable towards efficient, wide spectrum, low toxicity, peace
Full biological pesticide and insect hormone type agricultural chemicals direction develops, and meets the demand in market.In terms of acaricidal research, both at home and abroad
Many scholars have made substantial amounts of work.
Ethyl oleate is a kind of fatty acid ester, is mainly used in the tough agent of lubricant, water repellent agent, resin, surfactant, doctor
Pharmaceutic adjuvant, the plasticizer of plastics, the preparation of ointment bases and other organic chemicals also serves as spices.Current ethyl oleate
The method for being mainly obtained by chemical synthesis, i.e., be made by ethanol and oleic acid through esterification or pass through another oleate
Ester exchange reaction is carried out together with ethanol to obtain.It can also obtain through refining and obtain from plant.In addition, ethyl oleate is as in honeybee body
A kind of pheromones, and the material can influence and adjust the behavior of honeybee in its internal content.
Found through being retrieved to existing technical literature, application report of the ethyl oleate in acaricide is prepared is there is no at present；
A kind of current also no and environment compatibility is good, harmonious acaricide to mammalian safe.
The content of the invention
Present invention aims at for deficiencies of the prior art, there is provided a kind of efficient, noresidue, production cost
Low, economical and practical, environment-friendly, high comprehensive performance ethyl oleate acaricide and application.
The present invention seeks to what is be achieved through the following technical solutions：
The present invention, which provides a kind of purposes of ethyl oleate, i.e. ethyl oleate, to be used to prepare acaricide.Wherein, the mite can be with
It is Tetranychus cinnabarinus, the plant evil mite such as Tetranychus urticae.
The present invention provides a kind of ethyl oleate acaricide, and the ethyl oleate acaricide is by ethyl oleate (i.e. bulk drug)
Constituted with customary adjuvant.The quality of wherein ethyl oleate accounts for the 0.05%-99% of ethyl oleate acaricide quality, and customary adjuvant is accounted for
The 1%-99.95% of ethyl oleate acaricide quality.
Preferably, the customary adjuvant refers to one or more in solubilizer, synergist, emulsifying agent, bleeding agent etc..
Preferably, the solubilizer is neopelex, Potassium dodecylbenzenesulfonate, polysorbate, poly- second two
Alcohol, sorbierite polyoxy ether, lignosulfonates, tea seed cake, take gleditsia sinensis etc. it is all in one or more；Emulsifying agent is sapn
Class, Tweens, ethylene glycol esters, propane diols esters and/or polyethylene glycol type nonionic surfactant etc.；Synergist is tea soap
Element, APEO etc.；Bleeding agent is azone etc..
Weigh ethyl oleate solvent according to aforementioned proportion to dissolve, selection adds various auxiliary materials, e.g., solubilizer, synergist,
Emulsifying agent, bleeding agent etc., according to various techniques, are made various forms of acaricides, for example：Pulvis, it is missible oil, suspending agent, dry
Suspending agent, emulsifiable concentrate, sustained release agent, aqueous emulsion, spray etc..Wherein, solvent can be water, ethanol, methanol, acetone, cyclohexanone,
One or more in all organic solvents such as petroleum ether, petroleum aromatic, purified petroleum benzin, ethyl acetate, toluene, dimethylbenzene.
The present invention provides a kind of acaricidal application of above-mentioned ethyl oleate, is specially：Added water under stirring at normal temperature
In ethyl oleate acaricide, it is diluted to after ethyl oleate i.e. bulk drug accounts for 0.5-40wt% concentration and be spray applied.
Compared with prior art, the present invention has following beneficial effect：
The invention provides a kind of new harmonious acaricide to person poultry safety, environmentally friendly, to ecological environmental protection,
The comprehensive regulation of human health and disease all has far-reaching significance.Compared with traditional agricultural chemicals, the present invention has following spy
Point and advantage：
(1) ethyl oleate is a kind of natural products, with nontoxic, the features such as degradable, is for people, animal and ecological environment
Friendly, it is safe；
(2) ethyl oleate source is easy, it is possible to use esterification is synthesized, and can also directly be extracted from plant, method
It is simple and easy to apply, large-scale industrial production can be carried out；
(3) present invention is to find that ethyl oleate has mite killing bioactivity first, and is configured to acaricide first, is passed through
Experiment, to Tetranychus cinnabarinus preventive effect up to 98.2%.
