Description
Technical field
The present invention relates to field of pesticides more particularly to a kind of insecticide for grains storage agent containing multiple killing teichomycin and preparation method thereof with
And application.
Background technique
Storage pest, which refers to, lives in the places such as warehouse, processing factory, endangers the reserve, freight house, factory of various of animal or plant natures
Building, the pest for packing equipment, storage and means of transport and equipment.It is most to attach most importance in storage pest to anthropogenic influence that grain, which stores up pest,
The part wanted.
Grain storage insect pest control method can substantially be divided into physical pest killing and pest control with insecticide.
(1) physical pest killing.Including low-temperature insecticidal, controlled atmosphere desinsection, ozone desinsection, irradiation, microwave, radio frequency desinsection etc..First 3 kinds
Physical method for killing pests is more demanding for environment, equipment or air-tightness etc., and comparatively cost is also very high.Irradiation, microwave,
Radio-frequency technique need further to study, and the pretreatment before being used only in conveying grain into storehouse now is not widely applied in storehouse.
Physical method for killing pests has certain scope of application, individually is difficult to obtain ideal effect using a kind of technology.And
And due to higher cost, it is difficult to obtain preferable insecticidal effect under the premise of meeting cost-effectiveness requirement.
(2) pest control with insecticide.China is begun one's study very early and is solved using chemical agent grain Chu Wenti, can be divided mainly into
Fumigation action and action of contace poison.The medicament of fumigation action includes: chloropicrin, hydrogen phosphide, aluminum phosphate, zinc phosphide etc..Action of contace poison
Medicament include: malathion, Actellic etc..
Chemical method have desinsection efficiently thoroughly, use scope it is wide, at low cost, in the case where not moving grain at
The advantages of reason, can bring different degrees of but a disadvantage is that the chemical toxicity of many old ingredients is big to grain and environment
Pollution.There is certain toxic side effect to people, animal, having grown pest using the time can develop drug resistance.
Summary of the invention
Insecticide for grains storage agent that the purpose of the present invention is to propose to a kind of containing multiple killing teichomycin and preparation method thereof and application.
To achieve the goals above, present invention employs following technical solutions:
A kind of insecticide for grains storage agent containing multiple killing teichomycin includes following composition according to parts by weight: 40-50 parts of dichloroethanes,
6-10 parts of methyl formate, 4-8 parts of bromomethane, 10-15 parts of multiple killing teichomycin, 10-20 parts of emulsifier, 6-12 parts of microemulsion, You Jirong
15-20 parts of agent.
Further, the multiple killing teichomycin is powdery multiple killing teichomycin.
Further, the organic solvent is ethyl alcohol, any one in ether.
A kind of production method of the insecticide for grains storage agent containing multiple killing teichomycin,
Step 1: the multiple killing teichomycin of above-mentioned mass fraction is added portionwise in the organic solvent of above-mentioned mass fraction and is sufficiently stirred
It mixes, and is heated to certain temperature, so that multiple killing teichomycin is completely dissolved in organic solvent, obtain mixed liquor one；
Step 2: by the first of the dichloroethanes of above-mentioned mass fraction, the emulsifier of above-mentioned mass fraction, above-mentioned mass fraction
Sour methyl esters is added in mixed liquor one obtains mixed liquor two after mixing evenly；
Step 3: the microemulsion of the bromomethane of above-mentioned mass fraction and above-mentioned mass fraction is added drop-wise in mixed liquor two,
Stir to get fumigating insecticide；
Further, mixing time is 30~40min in the step 1, and stirring rate is 500~1000 turns/min.
Further, the heating temperature in the step 1 is 25-35 DEG C.
A kind of application method of the insecticide for grains storage agent containing multiple killing teichomycin exists residual spray uniform after fumigant insect killing dilution agent
On ground.
Further, the dilution ratio of the fumigating insecticide is 1:50.
Further, the dilution ratio of the fumigating insecticide is 1:100.
Further, every square metre of sprinkling 45-60mL of the fumigating insecticide.
The usefulness that the present invention has:
1, some pests that organic phosphorus equal insecticides are generated with resistance efficiently resistance management: are prevented and treated.
2, fumigant insect killing: the steam insecticidal properties of strength, even if pest does not contact with application surface, steam can also kill evil
Worm.
3, it is long to be detained holding effect: the inactive surfaces such as residual spray to wall and ground have the effect of the pest control of several months.
4, space water body processing residual is short: half-life period is only 3~8 days in environment, the risk after substantially reducing application.
5, without anti-repelling properties: pest understands continuous contact and reaches lethal dose.
6, toxicity is low: to mammal and other non-target animal low toxicities；It has verified that user and consumer's low-risk.
