Abstract
The invention discloses an agricultural products storage insecticide and its production method and use, which is the emulsifying agent of methylpyrimitate or aqueous emulsion of methylpyrimitate. The advantages include high performance, broad spectrum, low toxicity, low residual, and environmental protection. The insecticide is suitable for the prevention and cure of grain and agricultural product warehouse insects.
Description
Technical field
The present invention relates to a kind of storage pest control insecticide and production method and purposes.
Background technology
China prevents and treats on the method at the storage pest of grain and other agricultural product, and about 90% storage capacity all is to use highly toxic pesticide phosphine fumigation desinsection to guarantee storage safe.The agricultural product of sterilization of part hole capital after selling all securities and small lot store and use dichlorvos and other pesticide control pest to guarantee storage safe.Single phosphine fumigation control storage pest method was used more than 40 year continuously.As time goes on, more and more outstanding because of the long-term problem of using phosphine to embody: the first, phosphine belongs to highly toxic pesticide, and tame product safety and environmental pollution have been brought adverse influence, can cause stifling personnel's chromosome aberration and carcinogenic; The second, easy firing, storage, transportation, hidden danger safe in utilization are many.Every year poisons because of use phosphine causes and fire incident constantly takes place.China Oil and Food Import and Export Corporation's storage in this year company subordinate warehouse is because of using the dead people of hydrogen phosphide poisoning, and the initiation fire accident together; Three, storage pest has produced serious pesticide resistance to phosphine; Four, bigger to the influence of food quality and mucedin, quickened the aging speed of grain; Five, the long-term use of highly toxic pesticide has had a strong impact on the safety of agricultural products in China, and many export of farm produces are obstructed, and lack the market competitiveness in the world.
Western developed country has forbidden that highly toxic pesticide is used for the control of storage pest.At present the U.S., Britain etc. develop efficient, low toxicity, less-persistent pesticide pirimiphos-methyl pulvis or microcapsules technology in succession and carry out and mix the grain storage method and be used to prevent and treat storage pest, and by wide popularization and application.The FAO (Food and Agriculture Organization of the United Nation) and the World Health Organization have worked out the residual sanitary standard of pirimiphos-methyl, recommend as the grain storage protective agent.Condition is poor but China stores in a warehouse at present, and equipment and technology falls behind, particularly grain time of putting in storage long, the time of mixing grain while putting in storage may reach 1 ~ 2 month; Though single pirimiphos-methyl preparation stomach toxicity, the effect of tagging are good, poor permeability, smoked killing effect is not obvious; Pirimiphos-methyl pulvis technology is not suitable for China's control storage pest.
Summary of the invention
Problem at prior art exists the invention provides a kind of agricultural products storage insecticide, has the characteristic of efficient, low toxicity, low-residual, and is applicable to the storage pest control of China's grain and agricultural product.
Agricultural products storage insecticide provided by the invention is a kind of emulsifier of pirimiphos-methyl or the aqueous emulsion of pirimiphos-methyl, the emulsifier of pirimiphos-methyl is made up of pirimiphos-methyl, emulsifier, stabilizing agent, Esbiothrin, its proportioning is: the parts by weight with pirimiphos-methyl are mete-wand for 100 parts, and the parts by weight of other components are as follows:
15 parts-100 parts of emulsifier
15 parts-50 parts of stabilizing agents
0.25 part-1.2 parts of Esbiothrins;
The aqueous emulsion of pirimiphos-methyl is made up of pirimiphos-methyl, emulsifier, stabilizing agent, Esbiothrin, water, and its proportioning is: the parts by weight with pirimiphos-methyl are mete-wand for 100 parts, and the parts by weight of other components are as follows:
25 parts-150 parts of emulsifier
15 parts-75 parts of stabilizing agents
0.5 part-2.5 parts of Esbiothrins;
250 parts-1000 parts in water.
Wherein emulsifier is selected from one or more the mixture in polyvinyl chloride castor oil, glycerine fatty acid fat, sorbitan fatty acid fat, the polyvinyl chloride fatty acid.Stabilizing agent is: epoxidized soybean oil.
The preparation method of agricultural products storage insecticide is divided into the preparation of the aqueous emulsion of the preparation of emulsifier of pirimiphos-methyl and pirimiphos-methyl.
The emulsifier preparation method of pirimiphos-methyl is: by prescription pirimiphos-methyl, emulsifier, stabilizing agent, Esbiothrin are added dispenser and carry out emulsification.
The method for producing aqueous emulsion of pirimiphos-methyl is: earlier pirimiphos-methyl, emulsifier, stabilizing agent, Esbiothrin are added dispenser by prescription and carry out emulsification, add entry then, again emulsification.
Dispenser can be selected high speed agitator, high-shear emulsion machine, high pressure homogenizer, supersonic generator for use.Select for use the high-shear emulsion machine effect best.
The purposes of agricultural products storage insecticide provided by the invention is that the aqueous emulsion with the emulsifier of pirimiphos-methyl or pirimiphos-methyl becomes gas phase by liquid phase and sends in the storage, and by osmosis, medicament enters in the grain, realizes the control of insect.
The present invention has following technique effect:
This agricultural products storage insecticide has efficiently, the characteristic of wide spectrum, low toxicity, low-residual, Environmental Safety.The working concentration 1-5ppm of pirimiphos-methyl just can effectively prevent and treat red flour beetle, corn picture in grain depot.
This agricultural products storage utilization of pesticides method is easy, atomizing, gasification result is good, the molecular motion of having quickened has ultra micro infiltration, insecticidal effect distinguishing feature completely rapidly, and it is as the effect spy good that phosphine is formed the long angle of serious drug-fast storage pest ostomatid, red flour beetle, corn.
This agricultural products storage insecticide applied range, be applicable to the control of grain and agricultural products storage insect, comprise foodstuff anthelminthic test, the hole capital after selling all securities disinfection, food production workshop, rice mill, feed factory, flour mill's workshop disinfection, the control of insect in agricultural product warehouses such as medicinal material, tobacco.
