Embodiment 1

[0033] (1) According to the formula of Example 1 in Table 1, epoxiconazole, sucrose fatty acid ester, sodium tridecyl sulfosuccinate, sodium alginate, urea, sodium acetate, saponin powder, polyoxyethylene Glycerin ether and water are stirred and mixed to form a slurry, which is pulverized in a ball mill.

[0034] (2) Put it in a grinder for ultrafine pulverization, and control the average particle size to 2-4 μm.

[0035] (3) Homogenize in a homogenizer to homogenize the particles.

[0036] The prepared suspending agent is a viscous and homogeneous liquid in appearance, and its average particle diameter (D50) is 2.4 μm as measured by a Malvern laser particle size distribution analyzer.

Abstract

The invention discloses an epoxiconazole suspending agent and a preparation method thereof and belongs to the field of processing of pesticide preparations. The epoxiconazole suspending agent is prepared from the following raw materials in percentage by weight: 10-15% of epoxiconazole, 8-14% of a surfactant, 0.2-0.5% of sodium alginate, 0.2-1% of urea, 0.5-1% of sodium acetate, 0.2-0.6% of shikakai powder, 0.02-0.05% of glycerine ethoxylate and the balance of water, wherein the surfactant is composed of sucrose fatty acid ester and sodium 1,4-dioxo-1,4-di(tridecoxy)butane-2-sulfonate. By utilizing the synergistic effect of the sucrose fatty acid ester and sodium 1,4-dioxo-1,4-di(tridecoxy)butane-2-sulfonate, aggregation of original medicine granules can be effectively avoided; the added urea is capable of improving the medium density and contributes to maintaining the suspension stability of the suspending agent; the epoxiconazole suspending agent disclosed by the invention has the advantages of being high in suspension rate, stable in long-term storage and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation processing, in particular to a epoxiconazole suspension and a preparation method thereof. Background technique [0002] As shown below, epoxiconazole is a systemic triazole fungicide, which mainly inhibits the synthesis of ergosterol and hinders the formation of the cell wall of bacteria, and the epoxiconazole molecule has a certain effect on a fungal enzyme (14-dencthylase). Strong affinity, compared with currently known fungicides, it can more effectively inhibit pathogenic fungi. Epoxiconazole can increase the chitinase activity of crops, lead to the contraction of fungal haustoria, and inhibit the invasion of pathogens. This is the unique characteristic of epoxiconazole among all triazole products. It has a good control effect on leaf spot, powdery mildew, rust on bananas, onions, garlic, celery, kidney beans, melons, asparagus, peanuts, sugar beets and other crops, as well as a...
