In the development of contemporary agriculture, pesticide microemulsions are becoming more and more popular. Many people are unfamiliar with this word. What is the microemulsion of pesticides, and what is the role of pesticide microemulsions? China Pesticide Network Xiaobian takes everyone to understand the pesticide microemulsion:
The pesticide microemulsion (ME) is a transparent or milky body formed by the active ingredient of the pesticide and the emulsifier, dispersant, antifreeze, stabilizer, and cosolvent uniformly dispersed in the matrix water.
The active ingredient of the microemulsion dispersed in water has a particle diameter of 0.01 to 0.1 m, and thus the appearance of the microemulsion is transparent or nearly transparent. The emulsifier is generally used in an amount of more than twice that of the active material, and requires a certain amount of an organic solvent and a solubilizing agent. The active material that can be processed into an aqueous emulsion can theoretically be processed into a microemulsion, but the processing concentration generally does not exceed 20%. The choice of emulsifier and solvent is critical, otherwise crystallization and phase inversion are highly prone to occur.
Foreign varieties have been 10% high-grade fenfluthrin, 5% cypermethrin, 30% sputum microemulsion and other commodities. China has 8% fenvalerate, 5% beta-cypermethrin and 10% abundance, 35% grass enemy and other microemulsions.
Microemulsions are generally more expensive than emulsifiable concentrates and emulsions (since emulsifiers and solvents are used in large amounts). In order to develop this dosage form, it should first be promoted on high value-added crops (such as vegetables and fruits) to improve the quality of vegetables and fruits, and then gradually expand the scope of application.
Pesticide microemulsions will play a pivotal role in the future development of agriculture.
