[0025] 1) Mix Pichamid and zeolite powder at a mass ratio of 10:1 and place them in a ball mill. Metal balls with different diameters from 0.5 to 15 mm are used in random proportions and used as grinding balls. After ball milling for 24-48 hours, it is formed to 95 More than % of the mixture with a particle size of less than 100nm; wherein, the mass ratio of ball to material is 100:1, and the speed of the ball mill is 500 rpm;

[0026] 2) Homogenize the mixture obtained in step 1) to form an insecticidal composition, wherein the homogenization pressure is 15000 bar, and the number of homogenization times is 6;

[0027] 2) Take the surfactant fatty alcohol polyoxyethylene ether, the co-surfactant n-butanol, the oil phase garlic oil and water to form a microemulsion, and slowly drop the insecticidal composition at a rate of 1 drop / 0.5-1 minute Add it into the microemulsion, stir it whi...

Embodiment 3

[0029] 1) Mix Pichamid and zeolite powder at a mass ratio of 8:1 and place them in a ball mill. Metal balls with different diameters ranging from 0.5 to 15 mm are used as grinding balls in random proportions. After ball milling for 24-48 hours, they are formed to 95 More than % of the mixture with a particle size of less than 100nm; wherein, the mass ratio of ball to material is 100:1, and the speed of the ball mill is 500 rpm;

[0030] 2) Homogenize the mixture obtained in step 1) to form an insecticidal composition, wherein the homogenization pressure is 13000 bar, and the number of homogenization times is 6;

[0031] 2) Mix surfactant sorbitol polyoxyethyl ether, co-surfactant n-butanol, oil phase garlic oil and water to form a microemulsion, and slowly add the insecticidal composition dropwise at a rate of 1 drop / 0.5-1 minute In the microemulsion, stir while adding at a rotating speed of 5000 rev / min, dropwise, emulsify in the emulsifying homogenizer for 60-120 minutes, fo...

Abstract

The invention discloses a method for processing a Paichongding nano-microemulsion pesticide. The method comprises the following steps: 1) mixing Paichongding and zeolite powder, adding the mixture into a ball mill, arbitrarily proportioning metal balls with different particle sizes of 0.5-15mm so as to serve as a grinding ball, performing ball milling for 24-48 hours, and forming a mixture of 95%or higher and with the particle size of less than 100nm; 2) homogenizing the mixture obtained in the step 1) so as to form an insecticidal composition; and 3) mixing a surfactant, a cosurfactant, an oil phase and water so as to form microemulsion, slowly dripping the insecticidal composition into the microemulsion at a rate of 1 drop per 0.5-1 minute, stirring at a rotation speed of 3000-5000 revolutions per minute while dropping, and emulsifying in an emulsifying homogenizer for 60-120 minutes after dropping completion, thereby obtaining the nano-microemulsion preparation. The Paichongding microemulsion pesticide processed by the method disclosed by the invention has excellent stability and the mean particle size of 20-50nm, and controlled drug release is realized while the control effectis improved.

Description

technical field [0001] The present invention relates to the field of plant protection, and in particular to a processing method of pichamidin nano microemulsion pesticide. Background technique [0002] my country is a big country in the world in the production and use of pesticides. The area of ​​chemical control of pesticides is as high as 7 billion mu every year, and the usage exceeds 2 million tons. After years of development, my country has formed a relatively complete pesticide industry system, which has played an escort role for the sustained and stable increase in agricultural production. [0003] However, most of the pesticides are poorly soluble compounds. Usually, carriers, solvents, auxiliaries, etc. must be added for dosage form processing before they can be diluted with water and sprayed. Due to the coarseness and poor dispersibility of the drug-loaded particles, during the spraying process of traditional pesticide formulations in the field, more than 70% of th...
