Description

technical field [0001] The invention relates to the field of pesticides, in particular to a suspoemulsion containing propiconazole and azoxystrobin and a preparation method thereof. Background technique [0002] Propiconazole (propiconazole), the chemical name is cis-trans-1-[2-(2,4-dichlorophenyl)-4-n-propyl-1,3-dioxolan-2-ylmethyl ]-1H-1,2,4-triazole is a triazole systemic fungicide developed by Ciba-Geigy, Switzerland. Propiconazole is a sterol demethylation agent with broad-spectrum and systemic properties. The appearance of the original drug is a light yellow sticky silk liquid, with a boiling point (13.3Pa) of 180°C, a vapor pressure (ZOoC) of 0.133mPa, a refractive index of 1.5468, and a specific gravity of 1.279 / cm3 at 20°C. The solubility in water is 110mg / L, easily soluble in organic solvents. Stable below 320°C, relatively stable to light, and not obvious in hydrolysis. It is relatively stable in acidic and alkaline media and does not corrode metals. Storage ...
