Abstract

The invention discloses a difenoconazole and propiconazole emulsion in water and a preparation method thereof, and the emulsion in water comprises the following components by weight percent: 13% to 30% of difenoconazole, 15% to 30% of propiconazole, 5% to 25% of acid solvent, 3% to 10% of emulsifier, 1% to 5% of antifoaming agent, 0.5% to 5% of antifreezing agent, 0% to 10% of penetrating agent and 100% of water supplying. In the invention, the difenoconazole and the propiconazole are prepared into high content emulsion in water which has obvious synergistic effect and can improve crop yield dramatically.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an emulsion in water of a fungicide combination and a preparation method thereof. Background technique [0002] Difenoconazole is a triazole fungicide with systemic property, visterol demethylation inhibitor, wide bactericidal spectrum, and page treatment can improve crop yield and ensure quality. Phylum and Alternaria, Ascodiospora, Cercospora and other genera of deuteromycetes, powdery mildew, rust and certain species of pathogenic bacteria have lasting protective and therapeutic activity. [0003] Propiconazole is a systemic triazole fungicide with protective and therapeutic effects, which can be absorbed by roots, stems, and leaves, and can quickly conduct upwards in plants. Propiconazole can prevent and control diseases caused by ascomycetes, basidiomycetes, and deuteromycetes, especially for wheat root rot, powdery mildew, and rice bakanae disease. [0004] In recent...
