Abstract
The present invention relates to a kind of processing method of compound insecticide, compositions such as the emulsification compound interpolation synergist of the present invention by chrysanthemum ester class and organophosphorus insecticides, emulsifier, obtain containing cypermethrin and the phoxim total amount is the uniform emulsified insecticide of 10-30%, reach and delay pesticide resistance, reduce toxicity and enlarge the purpose of desinsection scope.Insecticide component of the present invention can suppress detoxication in the pest body, promote the absorption of active ingredient in pest body, thereby solved the frequent use owing to agricultural fungicides, the pesticide resistance of pest is more and more stronger, the vicious circle that the usage amount of agricultural chemicals is also increasing.Insecticide of the present invention has efficiently, the characteristics of low consumption of low toxicity and wide spectrum.
Description
The present invention relates to a kind ofly by chrysanthemum ester and the compound interpolation emulsifier of organic phosphor, the emulsified insecticide that synergist and solvent are made belongs to insecticide.
For a long time, because a large amount of uses of agricultural fungicides, a large amount of insects easily develop immunity to drugs to insecticide, reduce lethality, this has just caused the pesticide resistance of insect more and more stronger, and the vicious circle that the usage amount of agricultural chemicals is also increasing has not only caused environmental pollution, and increased agriculture production cost, increased the weight of peasant's financial burden.
The object of the present invention is to provide a kind of effective ingredient of agricultural chemicals that can promote to absorb at the insect body surface, suppress the composite insecticide of detoxication in the pest body, solve the pesticide resistance that prevents insect, improve drug effect, problems such as wide spectrum low toxicity reduce cost.Has drug-fast insect body surface poor permeability from the physiological function of insect, the wax layer of parietal epidermis can prevent that noxious material from infiltrating polypide, and lethality is low, kills cotton aphid as using agricultural chemicals 1059, the aphid lethality of no pesticide resistance is 81%, and the aphid lethality that develops immunity to drugs only is 1%.Insecticide of the present invention adopts fat-soluble emulsifier to combine with cypermethrin, again with the compound synergy of organophosphorus insecticides, make the wax layer dissolving of insect body surface, destroying wax layer structure and be soup enters polypide and opens passage, thereby increased the lethality of insect greatly, the present invention selects dodecyl sodium sulfonate calcium and polyoxyethylene aliphatic alcohol ether and cypermethrin emulsification to prepare composite insecticide with the phoxim composite methods again, add Octachlorodipropyl Ether simultaneously and suppress the detoxication of insecticide in polypide, increase drug effect, reduce consumption, emulsified insecticide of the present invention uses dimethylbenzene to make cypermethrin and the phoxim total amount in insecticide be 10-30% as solvent, insecticide of the present invention is by the cypermethrin of 1-25%, the 10-25% phoxim, the 10-25% Octachlorodipropyl Ether, 3-15% emulsifier and organic solvent are formed.
Insecticide characteristics of the present invention are efficient, low consumption, good disinsection effect etc.Equal insecticidal effect if use cypermethrin typical concentrations 20% separately, and can be reduced to 1-2.5% in insecticide of the present invention.Phoxim typical concentrations 50% can be reduced to 10-25% in the insecticide of the present invention, can reduce cost and has reduced environmental pollution.Insecticide of the present invention bores common insect such as worm and comprises that acarid is all effective to aphid, two spotted spider mite, pear sucker, bean worm, corn, have the insecticidal effect of wide spectrum, and low toxicity, low-residual, during use to application on human skin mucous membrane, eye nose nonirritant.
Below in conjunction with the embodiment that kills fruit tree pest insect pear lice content of the present invention is described.

The dimethylbenzene surplus
The preparation method
1, the preparation of emulsifier
Get polyoxyethylene aliphatic alcohol ether and dodecyl sodium sulfonate calcium equivalent, progressively mix in batches and stir, emulsification is even,
2, the preparation of cypermethrin emulsion
Get cypermethrin and add dimethylbenzene 20ml dissolving, add the 1/3 even of emulsifier total amount again, in emulsion process, slowly add dimethylbenzene 30ml 25-30 ℃ of emulsification.
3, emulsification is good cypermethrin emulsion and phoxim mix, and add Octachlorodipropyl Ether and remaining emulsifier again after 25-30 ℃ of emulsification evenly, and slowly adding dimethylbenzene to cypermethrin and phoxim total amount is 10-30%.
Claims (3)
1, a kind of composite emulsifying insecticide that contains cypermethrin is characterized in that by phoxim 10-25% Octachlorodipropyl Ether 10-25%, polyoxyethylene aliphatic alcohol ether 3-8%, dodecyl sodium sulfonate calcium 3-8%, wherein one or more and cypermethrin 1-25% form, and surplus is a dimethylbenzene.
2, insecticide according to claim 1 is characterized in that the optimal proportion of cypermethrin in insecticide is 1.5-2.5%.
3, a kind of composite emulsifying method for producing insecticide is characterized in that:
Polyoxyethylene aliphatic alcohol ether and dodecyl sodium sulfonate calcium mixed in equal amounts is standby as emulsifier, cypermethrin is dissolved in the dimethylbenzene of 20-50ml, the emulsifier that adds total amount 1/3 is 25-30 ℃ of emulsification, obtain the cypermethrin emulsion and mix with phoxim and add Octachlorodipropyl Ether and all the other emulsifier again after 25-30 ℃ of emulsification evenly, slowly adding dimethylbenzene to the total amount of cypermethrin and phoxim is 10-30%.
