Abstract

The embodiment of the invention discloses a microemulsion containing difenoconazole and propiconazole, and belongs to the technical field of pesticides. 100% of the microemulsion containing difenoconazole and propiconazole is prepared from the following components in percentage by mass: 10-20% of difenoconazole, 10-20% of propiconazole, 10-25% of a surfactant, 20-30% of a solvent, 1-5% of a synergist, 2-5% of an anti-freezing agent, and the balance water; wherein the surfactant is prepared from triphenyl ethyl phenol polyoxyethylene ether, polyoxyethylene ether non-ions and bisamide sodium disulfonate according to the weight ratio of (3 to 6) : (2 to 3) : (2 to 3). The microemulsion provided by the invention is prepared from the environment-friendly solvent, and has the characteristics ofstable performance and obvious control effect; and the problems that a solvent in an existing microemulsion is not friendly to the environment and is not safe to use are solved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of pesticides, in particular to a microemulsion containing difenoconazole and propiconazole and a preparation method thereof. Background technique [0002] Difenoconazole is a triazole fungicide with systemic properties. It is a sterol demethylation inhibitor with a wide bactericidal spectrum. Leaf treatment or seed treatment can increase crop yield and ensure quality. Phylum, Basidiomycotina and includes Alternaria, Ascodiospora, Cercospora, Septoria, Coccidioides, Phoma, Septoria, Septoria, Black Star Deuteric fungi, powdery mildew, rust fungi and certain species of pathogenic bacteria including fungi have long-lasting protective and therapeutic activities. [0003] Propiconazole belongs to triazole fungicides in sterol inhibitors, its mechanism of action is to affect the biosynthesis of sterols, destroy the cell membrane function of pathogenic bacteria, and eventually lead to ce...
