Abstract
The invention relates to a plant acaricide suitable for preventing and controlling mites on cash crops, i.e. fruit trees, vegetables, and the like as well as a preparation and application thereof. The plant acaricide is prepared by adding a surface active agent, an emulsifying agent, a penetrating agent, a potentiating agent, and the like in Methyl linoleate. The plant acaricide is a plant source acaricide which has high efficiency and low toxicity and residual, is harmonic with the environment, and the like.
Description
Technical field
The present invention relates to the new purposes of methyl linoleate, particularly the new purposes of methyl linoleate in the preparation plant acaricide.
Background technology
Methyl linoleate English name: Methyl linoleate, molecular formula: C
19H
34O
2, molecular weight: 294; Be used for the preparation of pharmaceuticals and other organic chemicals.To air-sensitive.Water insoluble, be dissolved in common organic solvents such as ethanol, ether, can be miscible with dimethyl formamide, fat solvent and oils.Excitant is arranged.Can make by linoleic acid and methanol esterification.Will carry out the methyl esters or the derivatization of ethyl ester when general gas-chromatography is tested fatty acid, esterification method is a lot.Phytophagous mites is the important pest in the agricultural production, and it has a very wide distribution, and the harm host is many, and it is big that area takes place, and medicine resistance ability is strong, and is serious and restive to the loss that agricultural production causes.But still there be not the application report of methyl linoleate in the preparation plant acaricide in the existing document; Still do not have at present a kind of good with environment compatibility, to the harmonious miticide of mammalian safe.
Summary of the invention
The new purposes that the objective of the invention is to open methyl linoleate; Another object of the present invention is to the new purposes of open methyl linoleate in preparation plant resource miticide.
The present invention seeks to be achieved through the following technical solutions:
The application of methyl linoleate in the preparation plant acaricide.Mite extremely of the present invention can be to kill the female one-tenth mite of Tetranychus cinnabarinus.Methyl linoleate of the present invention adds conventional auxiliary material, according to common process, makes various forms of miticides, for example missible oil, suspending agent, pulvis, spray etc.
From Sigma company buy the pure product of standard---methyl linoleate has acaricidal activity.
Methyl linoleate miticide of the present invention is with the methyl linoleate dissolution with solvents, can selectively add the dissolving of solubilizer, synergist, emulsifier, bleeding agent promotion methyl linoleate therein, promptly can be used for mite extremely.
Among the acaricidal preparation method, solvent is selected from a kind of in water, ethanol, methyl alcohol, acetone, cyclohexanone, toluene, dimethylbenzene, benzinum, petroleum aromatic, the purified petroleum benzin; Solubilizer be neopelex, Potassium dodecylbenzenesulfonate, polysorbate, polyethylene glycol, sorbierite polyoxy ether, lignosulfonates, tea withered, take any in the Chinese honey locust; Synergist is any in Tea Saponin, 2-C1C6H4-N=OCH3SCH3, methylenedioxy benzene derivative, 6-vinyl capraldehyde, the Octachlorodipropyl Ether; Emulsifier is any in C15～17H31～37COONa, odium stearate, lauryl sodium sulfate, N-domiphen, APEO, polyethenoxy ether, paraoctyl phenol APEO, aliphatic alcohol polyethenoxy base ether, aliphatic acid polyethenoxy base ester, the alkylaryl sulfonates, can utilize the HLB value to select emulsifier, the HLB value obtains the good missible oil of emulsifiability between 15-18; Bleeding agent is any in emulsifier BP, azone, the triphen phosphorus.
The component of this missible oil is: methyl linoleate 20%～50%, solubilizer 50%～20%, emulsifier 10%, synergist 10%, bleeding agent 10%. Preferred methyl linoleate 50%, solubilizer 20%, emulsifier 10%, synergist 10%, bleeding agent 10%; Methyl linoleate 40%, solubilizer 30%, emulsifier 10%, synergist 10%, bleeding agent 10% or methyl linoleate 30%, solubilizer 40%, emulsifier 10%, synergist 10%, bleeding agent 10%; Methyl linoleate 20%, solubilizer 50%, emulsifier 10%, synergist 10%, bleeding agent 10%.Adopt spray pattern control herbivore mite, it is 4mg/ml that the pure methyl linoleate concentration of mite biological activity test missible oil is killed in the laboratory.
The invention provides a kind of and environment compatibility good, to the novel harmonious miticide of mammalian safe, the comprehensive regulation of ecological long term growth, human beings'health and evil mite is all had profound significance.Compare with traditional agricultural chemicals, the present invention has following characteristics and advantage: 1, methyl linoleate is general at occurring in nature, content is big, can become well to exploit natural resources; 2, fat-soluble characteristics do not cause pesticide injury, toxic residue to mammalian safe, to people and animals, ecological environment security; 3, carry out synthetic easily, very help carrying out suitability for industrialized production; 4, in conjunction with other effectively kill acaricidal composition in the preparation type plant, pharmaceutical mixture can further increase effective acaricidal action.
Following experimental example and embodiment are used to further specify but are not limited to the present invention.
Experimental example
With the methyl linoleate dissolve with ethanol, add emulsifier tween-80, according to methyl linoleate 50%, solubilizer 20%, emulsifier 10%, synergist 10%, bleeding agent 10%.Experimental result sees the following form:
Table 1 methyl linoleate is to the biologically active (24h, FAO method) of female one-tenth mite of Tetranychus cinnabarinus and ovum
Table 2 methyl linoleate is to the bioactive gradient (24h, FAO method) of the female one-tenth mite of Tetranychus cinnabarinus
Annotate: lowercase alphabet shows that the F value less than 0.05, has significant difference among the figure.
The result proves that methyl linoleate of the present invention has significant contact toxicity to the female adult worm of Tetranychus cinnabarinus.
Following embodiment all can realize the beneficial effect of experimental example of the present invention.
