Embodiment 1

[0034] (1) Jinggangmycin, epoxiconazole, sucrose fatty acid ester, tridecyl alcohol sulfosuccinate sodium, glycerol, sucrose, polyvinyl alcohol, saponin powder are mixed according to the formula of embodiment 1 in table 1 , polyoxyethylene glyceryl ether and water are stirred and mixed to form a slurry, which is pulverized in a ball mill.

[0035] (2) Put it in a grinder for ultrafine pulverization, and control the average particle size to 2-4 μm.

[0036] (3) Homogenize in a homogenizer to homogenize the particles.

[0037] 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 a pesticide suspending agent compounded by Jinggangmycin and epoxiconazole and a preparation method thereof, belonging to the field of pesticide preparation processing. The compounded pesticide suspension of Jinggangmycin and epoxiconazole is made up of the following raw materials in percentage by weight: Jinggangmycin 6-10%, epoxiconazole 4-8%, surfactant 10-12%, glycerol 3‑5%, 0.5‑2% sucrose, 0.2‑1% polyvinyl alcohol, 0.05‑0.2% saponin powder, 0.04‑0.08% polyoxyethylene glyceryl ether, the balance is water; the surfactant is composed of sucrose fatty acid ester and sodium tridecyl sulfosuccinate. The invention utilizes the synergistic effect of sucrose fatty acid ester and ditridecyl sulfosuccinate sodium to effectively prevent the aggregation of the original drug particles; adding sucrose increases the density of the medium, which helps to maintain the suspension stability of the suspending agent; The invented pesticide suspension compound of Jinggangmycin and epoxiconazole has the advantages of high suspension rate and long-term storage stability.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation processing, in particular to a pesticide suspension composed of Jinggangmycin and epoxiconazole and a preparation method thereof. Background technique [0002] Jinggangmycin (see structural formula I) is an antibiotic produced by actinomycetes. It has strong systemic properties, is easily absorbed by bacterial cells and conducts rapidly therein, interfering with and inhibiting the growth and development of bacterial cells. It is mainly used for the prevention and control of rice sheath blight, rice smut, corn leaf spot, vegetables, cotton, beans and other crop diseases. Years of large-scale field use results have fully demonstrated its characteristics as an environmentally friendly pesticide with "high control efficiency, no harm, and no pollution", and is well received by users at home and abroad. [0003] Epoxiconazole (see structural formula II) is a kind of systemic triazole bac...
