Abstract
The invention discloses a compound fumigation pesticide containing natural essential oil, comprising the following components in parts by weight: 70 to 90 parts of eucalyptus oil containing no less than 80% by weight of eudesmin, 5 to 15 parts of DDVP missible oil containing no les than 80% by weight of DDVP and 4 to 10 parts of ethyl formate. The pesticide uses natural essential oil as main active ingredients, has high insecticidal efficiency and rapid effect, effectively solves the problems of high toxicity, awful smell, easy drug-resistant production of pests of conventional fumigation pesticides, and the like, avoids the pollution on the environment and storage materials, and has fragrant odour and convenient use. The invention also provides a preparation method of the pesticide. In the invention, the eucalyptus oil, the DDVP and the ethyl formate are sequentially added to a mixer according to the weight parts, the mixer is immediately closed, and the mixture is stirred for uniformly mixing, and the uniformly mixed materials are filtered to prepare the pesticide. The method has the advantages of simple process, easy operation, short production period and good reproducibility, and is very suitable for industrial production.
Description
Technical field
The present invention relates to a kind of compound fumigation pesticide, particularly a kind of compound fumigation pesticide that contains natural plant essential oils and preparation method thereof.
Background technology
The reserve insect pest can cause the massive losses of grain, archives, historical relic.L.bostrychophila, red flour beetle, corn weevil, lesser grain borer adaptability are strong, and feeding habits are assorted, are the important pests of grain, archives, historical relic, and paper, fabric and grain are caused great harm, be storage with transportation in a big troubling problem.
In order to reduce even avoid the harm of insect, people had once developed such as chemical fumigation insecticides such as phosphine, Celfume, dichlorvos, camphor balls, the steam of the medicament that utilization is easy to volatilize, the respiratory system by insect or penetrate polypide by body wall membranous is poisoned to death insect rapidly.These chemical fumigation insecticides play a part to be good; But because chemical insecticide is eliminated by market gradually to problems such as health and environmental hazard are big and develop immunity to drugs.Though now avoided some shortcomings of chemical fumigation insecticide, can't reach the specific (special) requirements of grain, archives, the preservation of historical relic storage on formulation and the result of use fully with conventional insecticide.
Based on insect serious day by day and existing common insecticides to the resistance problem of chemical fumigation insecticide all limitations, new global challenge has been proposed to relevant researcher, require to be devoted to seek new fumigant, develop new substitute technology.
Existing scientist has made control stored product insect Research on effect to the extract of many plants, a large amount of evidences: have volatile plant extract agent the prospect of using is preferably arranged.Plants essential oil is because of containing plurality of active ingredients, and action site is many, and pest is difficult for developing immunity to drugs, and can participate in the circulation of energy and material in environment, carries out metabolism, and have do not have accumulation, environmentally safe, characteristics such as agricultural chemicals enrichment do not take place.Adopt the main active of natural plant essential oils, can reduce toxicity of pesticides greatly, solve the pesticide resistance problem of general insecticide effectively, and avoid pollution environment and object of protection as insecticide.
Summary of the invention
In view of this; one of purpose of the present invention provides a kind of compound fumigation pesticide that contains natural plant essential oils; with the natural plant essential oils is main active; insecticide efficiency height, effect are rapidly; in the good penetrability of storage in the windrow, residual rate is low, solved effectively the conventional reserve of existing usefulness with the toxicity of fumigating insecticide greatly, problem such as the smell is awful, insect easily develops immunity to drugs; and pollution to environment and object of protection, fragrant odour, easy to use have simultaneously been avoided.
The compound fumigation pesticide that contains natural plant essential oils of the present invention comprises following composition by weight: eucalyptus oil 70-90 part, DDVP missible oil 5-15 part and Ethyl formate 4-10 part;
The mass fraction of Cineole 〉=80% in the described eucalyptus oil, mass fraction 〉=80% of DDVP in the described DDVP missible oil.
Further, comprise following composition by weight: eucalyptus oil 80-90 part, DDVP missible oil 8-12 part and Ethyl formate 5-8 part.
Two of purpose of the present invention provides the described method that contains the compound fumigation pesticide of natural plant essential oils of preparation, may further comprise the steps:
(1) take by weighing eucalyptus oil, DDVP missible oil and Ethyl formate respectively in described ratio, the order according to eucalyptus oil, DDVP missible oil, Ethyl formate joins raw material in the blender successively again, and airtight immediately, gets mixed material;
(2) stir described mixed material to mixing, filter, obtain the required compound fumigation pesticide that contains natural plant essential oils.
Need to prove that DDVP of the present invention is meant O, O-dimethyl-O-(2, the 2-dichloro) vinyl phosphate has another name called dichlorvos.
The invention has the beneficial effects as follows:
The compound fumigation pesticide that contains natural plant essential oils of the present invention has following advantage:
1,, pest many based on the eucalyptus oil action site be difficult for developing immunity to drugs, in environment, can participate in energy and material circulation, carry out metabolism, have do not have accumulation, environmentally safe and the advantage of agricultural chemicals enrichment do not take place; with the main active of eucalyptus oil as insecticide; reduce toxicity of pesticides greatly; solve the pesticide resistance problem of general insecticide effectively, and avoid pollution environment and object of protection.
2, the DDVP drug effect is outstanding, though strong toxicity, but a small amount of composite use toxic hazard is little, but can produce good insecticidal effect, Ethyl formate is widelyd popularize as a kind of novel Green Chemistry fumigant, the composite use of DDVP, Ethyl formate and eucalyptus oil is had desirable stifling performance and tangible synergy, several archives insects, grain storage pest (as l.bostrychophila, red flour beetle, corn weevil, lesser grain borer) are had excellent killing effect.
3, insecticide efficiency height, effect rapidly, the good penetrability in the storage windrow, residual rate is low, fragrant odour, easy to use is applicable to the protection to stored goods such as grain, archives and historical relics simultaneously.
The method technology of preparation of the present invention is very simple, and operation is very easy to and good reproducibility, and life cycle of the product is short simultaneously, and the production efficiency height is suitable for carrying out industrialization production very much.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can obtain instruction from the practice of the present invention to investigating hereinafter.
