Embodiment 1

[0039] Embodiment 1 (preparation method of 1% propiconazole ultra-low dosage preparation)

[0040] Raw material formula: by weight percentage, take propiconazole 1%, 21-25 carbon petroleum fraction 10%; surfactant, Nongru No. 500 2%; solvent, methylated rubber fruit oil 85%; cosolvent, dimethyl Sulfoxide 2%.

[0041] Preparation method: First, the active ingredient propiconazole 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-α-methyl]-1-hydrogen- Add 1,2,4-triazole together with solvent and co-solvent into the preparation kettle, and heat to 45°C to dissolve while stirring. After completely dissolving, add surfactant, petroleum fraction, anti-ultraviolet agent and light stabilizer , continue to stir until it becomes a transparent homogeneous solution. Cool to room temperature, filter to remove a small amount of residue, analyze and test the filtrate, and pack it for storage and transportation after passing the test.

Abstract

The invention relates to propiconazole ultra-low volume preparation and a preparation method thereof. The propiconazole ultra-low volume preparation is characterized by comprising the following components in percentage by weight: 1-20 percent of propiconazole, 1-20 percent of petroleum distillate, 0.1-15 percent of surfactant, 45-90 percent of solvent, 0.05-5 percent of ultraviolet screener, 0.01-5 percent of light stabilizer and 1-20 percent of cosolvent. The preparation method is characterized by comprising the following steps of: adding active ingredients, the solvent and the cosolvent together in a preparation kettle, heating to 15-60 DEG C to ensure that the active ingredients, the solvent and the cosolvent are completely dissolved while stirring, adding the surfactant, the propiconazole, the ultraviolet screener and the light stabilizer and continuously stirring until the mixture becomes a transparent and homogeneous liquid. The invention has convenient process, high use rate of pesticide and few pesticide application times when being used for controlling fungal diseases, thereby being suitable for ultra-low volume spraying controlling various diseases such as powdery mildew, anthracnose, corynespora leaf fall disease, and the like of gum leaves.

Description

technical field [0001] The invention relates to an ultra-low dosage preparation of propiconazole and a preparation method thereof. Background technique [0002] The chemical name of propiconazole is 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-α-methyl]-1-hydrogen- 1, 2, 4-triazole can be absorbed by plant roots, stems and leaves, and quickly conduct upward. The mechanism of action is to inhibit fungal ergosterol synthesis, destroy the physiological function of fungal cell membrane, and cause fungal death. Propiconazole can prevent and control diseases caused by ascomycetes, basidiomycetes and deuteromycetes, and can be used to prevent and control rubber tree powdery mildew, anthracnose, and Corynesporium leaf defoliation. Propiconazole has the characteristics of wide bactericidal spectrum, high activity, fast bactericidal speed, long-lasting effect, strong systemic conductivity, etc., and has become a representative variety of emerging broad-spectrum fungicides of lar...
