The invention provides application of ethyl oleate and an ethyl oleate acaricide. Ethyl oleate is applied to preparation of the acaricide. The ethyl oleate acaricide is composed of ethyl oleate and conventional accessory materials, wherein the mass of ethyl oleate accounts for 0.05 to 99% of the mass of the ethyl oleate acaricide while the accessory materials account for 1 to 99.95%. The acaricide provided by the invention is a novel, harmonious and environment-friendly acaricide safe to people and livestock and is of profound significance to protection of the ecological environment, human health and comprehensive control of diseases.
Description
Technical field
The present invention relates to a kind of miticide of technical field of pesticide, particularly, relate to the novelty teabag of a kind of ethyl oleate miticide and ethyl oleate.
Background technology
The crops of phytophagous mites all over the world are all found, it has, and volume are little, breeding is fast, strong adaptability and the feature such as easily to develop immunity to drugs, be the pest communities of generally acknowledged very difficult control.The most dependence on import of miticide used on the pesticide market of current China, the acaricidal expense of import accounts for 88.8% of general import agricultural chemicals expense.And the loss that mite class causes crop, within 30 years, there is obvious increase in the past.Main cause is intensive monoculture and uses non-specific insecticide.Next is because the growth time of a generation of mite class is shorter, can produce resistance rapidly to original miticide.These insecticides often acaricidal activity are not high, eliminated mite class natural enemy while killing mite class yet.At present, 3R problem i.e. residual (Residue), resistance (Resistance) and the pest resurgence (Resurgence) of chemical pesticide generally receives the concern of people, the understanding of the mankind to agricultural chemicals is also more and more deep, the use of agricultural chemicals is not focused on killing off the insect pests, but more focuses on regulating.Therefore, use obligate miticide to become the major measure of control phytophagous mites, the inevitable biopesticide towards efficient, wide spectrum, low toxicity, safety of acaricidal development and insect hormone type agricultural chemicals future development, meet the demand in market.In acaricidal research, many scholars have done a large amount of work both at home and abroad.
Ethyl oleate is a kind of fatty acid ester, is mainly used in lubricant, water repellent agent, the tough agent of resin, surfactant, pharmaceutical auxiliary material, the plasticizer of plastics, the preparation of ointment bases and other organic chemicals, is also used as spices.The acquisition of current ethyl oleate is mainly by the way of chemosynthesis, namely obtained or carry out ester exchange reaction by another kind of oleate together with ethanol and obtain through esterification by ethanol and oleic acid.Also can obtain through refining from plant and obtain.In addition, ethyl oleate is as a kind of pheromones in honeybee body, and the content of this material in its body can affect and regulate the behavior of honeybee.
Through finding existing technical literature retrieval, there is no ethyl oleate at present and preparing the application report in miticide; There is no at present a kind of, harmonious miticide to mammalian safe good with environment compatibility yet.
Summary of the invention
The object of the invention is for prior art above shortcomings, provides that a kind of efficient, noresidue, production cost are low, economical and practical, the ethyl oleate miticide of environmental friendliness, high comprehensive performance and application.
The present invention seeks to be achieved through the following technical solutions:
The invention provides a kind of purposes of ethyl oleate, namely ethyl oleate is for the preparation of miticide.Wherein, the plants such as described mite can be Tetranychus cinnabarinus, Tetranychus urticae evil mite.
The invention provides a kind of ethyl oleate miticide, described ethyl oleate miticide is made up of ethyl oleate (i.e. bulk drug) and customary adjuvant.Wherein the quality of ethyl oleate accounts for the 0.05%-99% of ethyl oleate miticide quality, and customary adjuvant accounts for the 1%-99.95% of ethyl oleate miticide quality.
Preferably, described customary adjuvant to refer in solubilizer, synergist, emulsifier, bleeding agent etc. one or more.
Preferably, described solubilizer is neopelex, Potassium dodecylbenzenesulfonate, polysorbate, polyethylene glycol, sorbierite polyoxy ether, lignosulfonates, tea are withered, take Chinese honey locust etc. all in one or more; Emulsifier is spans, Tweens, glycol ester class, propylene glycol ester class and/or polyethylene glycol type non-ionic surface active agent etc.; Synergist is Tea Saponin, APEO etc.; Bleeding agent is azone etc.
Ethyl oleate dissolution with solvents is taken according to aforementioned proportion, selection adds various auxiliary material, as, solubilizer, synergist, emulsifier, bleeding agent etc., according to various technique, make various forms of miticide, such as: pulvis, missible oil, suspending agent, dry suspending agent, emulsifiable concentrate, sustained release agent, aqueous emulsion, spray etc.Wherein, solvent can be one or more in all organic solvents such as water, ethanol, methyl alcohol, acetone, cyclohexanone, benzinum, petroleum aromatic, purified petroleum benzin, ethyl acetate, toluene, dimethylbenzene.
The invention provides the acaricidal application of a kind of above-mentioned ethyl oleate, be specially: under stirring at normal temperature, water is joined in ethyl oleate miticide, make it be diluted to after ethyl oleate and bulk drug account for the concentration of 0.5-40wt% to spray to use.
Compared with prior art, the present invention has following beneficial effect:
The invention provides a kind of to person poultry safety, environmentally friendly novel harmonious miticide, all there is profound significance to the comprehensive regulation of ecological environmental protection, human health and disease.Compared with traditional agricultural chemicals, the present invention has following characteristics and advantage:
(1) features such as ethyl oleate is a kind of natural products, has nontoxic, easy degraded are friendly for people, animal and ecotope, safety;
(2) ethyl oleate source is easily, and esterification can be utilized to synthesize, also can from plant extracting directly, method is simple, can carry out large-scale industrial production;
(3) the present invention is that Late Cambrian ethyl oleate has and kills mite biologically active, and is mixed with miticide first, through experiment, can reach 98.2% to Tetranychus cinnabarinus preventive effect.
