The acaricide is a novel, harmonious and environment-friendly acaricide safy 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 technical field of pesticide, concrete, relate to a kind of purposes and cupreol linoleate miticide of cupreol linoleate.
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.
Cupreol linoleate (β-sitosterol linoleate), pale yellow oil, molecular formula: C
47h
800
2, molecular weight: 676, is a kind of important phytosterin ester, can be obtained by cupreol and linoleic acid through esterification, as such as adopting organic phase enzymatic catalysis esterification, also can obtain through refining from plant and obtain, as such as the river radix paeoniae rubrathe, peel of cape jasmine fruit etc.It not only can improve the oil-soluble of sterol, conveniently applies in food processing, also has the biological function of cupreol and linoleic acid two kinds of active components concurrently, and now studies have reported that it has very strong anti-oxidant and bactericidal action.
Through finding existing technical literature retrieval, there is no cupreol linoleate 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 present invention is directed to prior art above shortcomings, provide that a kind of efficient, noresidue, production cost are low, economical and practical, a kind of cupreol linoleate miticide of environmental friendliness, high comprehensive performance and preparation thereof and novelty teabag.
The present invention seeks to be achieved through the following technical solutions:
The invention provides a kind of purposes of cupreol linoleate, be applied to by cupreol linoleate and prepare miticide.
Preferably, the plants such as described mite can be Tetranychus cinnabarinus, Tetranychus urticae evil mite.
The invention provides a kind of cupreol linoleate miticide, described miticide is made up of cupreol linoleate (i.e. bulk drug) and customary adjuvant.Wherein the quality of cupreol linoleate accounts for the 0.05%-99% of cupreol linoleate miticide quality, and customary adjuvant accounts for the 1%-99.95% of cupreol linoleate miticide quality.
Preferably, described customary adjuvant be 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.
Preferably, described emulsifier be in spans, Tweens, glycol ester class, propylene glycol ester class and/or polyethylene glycol type non-ionic surface active agent etc. one or more.
Preferably, described synergist be in Tea Saponin, APEO etc. one or more.
Preferably, described bleeding agent is azone etc.
Take certain cupreol linoleate dissolution with solvents, selection adds various auxiliary material, picture 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 acaricidal application of the present invention's above-mentioned cupreol linoleate, be specially: water is joined in cupreol linoleate miticide under stirring at normal temperature, make it be diluted to after cupreol linoleate 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 cupreol linoleate is a kind of natural products, has nontoxic, easy degraded are friendly for people, animal and ecotope, safety;
(2) cupreol linoleate 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 cupreol linoleate has and kills mite biologically active, and is mixed with miticide first.Through experiment, can 95.3% be reached to Tetranychus cinnabarinus preventive effect.
