Abstract
The invention relates to a botanical acaricides applied to preventing mites on industrial crops such as fruit trees, vegetables and the like as well as a preparation method and application thereof. The botanical acaricides is prepared from ethyl palmitate adding with surfactant, emulsifier, penetrant, synergist and the like, and has the characteristics of high efficiency, low toxicity, low residue, environment friendliness and the like.
Description
Technical field
The present invention relates to the new purposes of ethyl palmitate, particularly the new purposes of ethyl palmitate in preparation plant resource miticide.
Background technology
Ethyl palmitate has another name called ethyl palmitate, molecular formula: CH
3(CH

3, colourless liquid or colourless acicular crystal, water insoluble, be used for organic synthesis, spices and essence etc.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 ethyl palmitate in preparation plant resource miticide 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 ethyl palmitate; Another object of the present invention is to the new purposes of open ethyl palmitate in preparation plant resource miticide.
The present invention seeks to be achieved through the following technical solutions:
The application of ethyl palmitate in preparation plant resource miticide.Mite extremely of the present invention can be to kill the female one-tenth mite of Tetranychus cinnabarinus.Ethyl palmitate 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.
Ethyl palmitate miticide of the present invention is with the ethyl palmitate dissolution with solvents, can selectively add the dissolving of solubilizer, synergist, emulsifier, bleeding agent promotion ethyl palmitate 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 Tea Saponin, 2-C

3, any in the methylenedioxy benzene derivative, 6-vinyl capraldehyde, 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: ethyl palmitate 20%～50%, solubilizer 50%～20%, emulsifier 10%, synergist 10%, bleeding agent 10%. Preferred ethyl palmitate 50%, solubilizer 20%, emulsifier 10%, synergist 10%, bleeding agent 10%; Ethyl palmitate 40%, solubilizer 30%, emulsifier 10%, synergist 10%, bleeding agent 10% or ethyl palmitate 30%, solubilizer 40%, emulsifier 10%, synergist 10%, bleeding agent 10%; Ethyl palmitate 20%, solubilizer 50%, emulsifier 10%, synergist 10%, bleeding agent 10%.Adopt spray pattern control herbivore mite, it is 2mg/ml that the pure ethyl palmitate 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, ethyl palmitate 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 ethyl palmitate petroleum ether dissolution, add emulsifier tween-80, according to ethyl palmitate 50%, solubilizer 20%, emulsifier 10%, synergist 10%, bleeding agent 10%.Experimental result sees the following form:
Table 1 ethyl palmitate is to the biologically active (24h, FAO method) of the female one-tenth mite of Tetranychus cinnabarinus
Table 2 ethyl palmitate 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 ethyl palmitate 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.
