Description

A kind of missible oil that contains permethrin, Bassa and malathion

A kind of missible oil that contains permethrin, Bassa and malathion relates to the Pesticidal composition technical field, belongs to the broad spectrum insecticide mixture.

In order to improve the safety of agricultural chemicals, control is also eliminated residue of pesticide and is produced the pollution of emission to natural environment.The relevant rules increasingly stringent in various countries.The most noticeable in the desinsection is pyrethroids.The gross yield of American and Britain, day, method etc. has surpassed 500 tons (in 100% effective ingredient) at present, and year countries in the world are estimated to increase progressively 2.5% to the demand of pyrethroid.Extensive use the dichloro phenylate arranged, the chrysanthemum ester, cypermethrin, decis and the speed chrysanthemum ester that goes out, though their drug effects are high, the desinsection scope is wide, and is very safe again to environment, relatively poor to the acarid killing effect.(mite class worm is various in style, and it is wide to distribute, and fertility is strong, endangers a very big class pest).Therefore, the acaricidal activity of raising pyrethroid becomes important exploitation problem.

At present used Pesticidal mixture made major part is two composite mixtures, obviously is better than single agent to the retarding action of pest resistance to insecticide development with to the preventive and therapeutic effect of insect pest.But the synergy amplitude of mixture and different exist the very big-differences of control efficiency because of component and proportioning.The disclosed a kind of agriculture chemical compounding agent of Chinese patent CN87101394.0 kills emulsion for cleaning for one times, be effective ingredient mainly with sour cyanogen ether-ether and phoxim, being equipped with suitable emulsifier and solvent complex and making, is composite dose of a kind of Synergistic fertilizer that is applicable to control vegetable-crop pest-insect, high-efficiency low-toxicity.The disclosed Pesticidal mixture made of CN90103780.X contains cypermethrin, malathion, synergy phosphorus, No. 30 machine oil, emulsifier and solvents.Though above-mentioned compound agricultural insecticide has better prevention insect effect, insect is difficult for producing drug resistance, synergistic effect is not remarkable, in use, can not reduce the consumption of effective ingredient.The application of composite lethane is more and more wider, and further exploitation is efficient, and low toxicity, low-residual, wide spectrum (effectively, safety, stable, multi-functional) are the needs of agricultural chemicals development.

The objective of the invention is to overcome above-mentioned weak point, thereby provide the medicament that a kind of insecticidal spectrum is wide, use is wide, insect to multiple effect has killing action, to the also effective a kind of missible oil that contains permethrin, Bassa and malathion of sanitary insect pests such as mosquitos and flies, cockroach, bedbug.

Main solution of the present invention is achieved in that it mainly adopts permethrin, malathion is effective ingredient.In effective ingredient: the chlorine chrysanthemumic acid is 4.5-8.5%, malathion 12-18%.It is characterized in that adding Ba Sha in effective ingredient is 7.5-13.5%, is equipped with synergist and emulsifier, and supplies surplus with liquid paraffin and carry out composite dose.In the synergist: Octachlorodipropyl Ether is 4.5-8.5%, and synergy phosphorus is 12-19%.In the emulsifier, alkyl sulfide polyoxy alkene ether-10 is: 12-18%; Hexadecyltrimethylammonium chloride is 4-6%.

The missible oil that contains permethrin, Bassa and malathion that uses above-mentioned prescription to make is unique application cationic surfactant in the present domestic agricultural insecticide; In formulation of pesticide, adopt liquid paraffin without organic solvent, and the ternary built agent of utilization double increase agent.Co-toxicity coefficient of the present invention is 371.32, and composite dose of synergistic effect is remarkable, and a large amount of field trials have proved its high efficiency and broad spectrum activity, and virulence LC50 is minimum to be 31.61PPM..
