Embodiment Construction

[0023] Such as figure 1 Shown, the invention provides a kind of preparation method of tebuconazole suspending agent, described preparation method comprises the following processing steps:

[0024] Step 1: For the first batching, put the tebuconazole original drug and additives in an appropriate ratio into the emulsification tank, stir with a wooden stick to form a uniformly mixed material;

[0025] Step 2: Turn on the high-speed mixer and emulsify the above materials in the emulsification tank;

[0026] Step 3: The emulsified material enters 2 channel-connecting sand mills for sand grinding in turn, and the sanding time of the first sand mill is not less than 2 hours, and the sanding time of the second sand mill is not less than 2 hours. Hour;

[0027] Step 4: After sanding, use 50kg of tap water to clean the remaining materials in the equipment and pipelines, and then put the sanded materials into the pre-designated high-level tank for mixing;

[0028] Step 5: Add 80kg of ...

Abstract

The invention discloses a preparation method of tebuconazole suspension concentrates used for preventing crop rust, powdery mildew, net blotch, foul foot and gibberella zeaze petch of wheat and barley, groundnut early leaf spot, exobasidium vexans massee of tea plants, and bunt smut. The preparation method comprises the following steps of dispensing, emulsifying, sanding, mixing, secondary-dispensing, stirring, canning and the like, wherein all components are prepared at the first dispensing according to a certain weight. The invention prevents products from layering, degrading and agglomerating, and has the advantages of good product stability, good use effect, low production cost, high drug effect, and good economic benefit.

Description

technical field [0001] The invention relates to a preparation method of pesticides, in particular to a method for preventing and treating crop rust, powdery mildew, net spot, root rot, wheat scab, peanut brown spot, tea tree tea cake disease, wheat black The preparation method of the tebuconazole suspension concentrate of ear disease. Background technique [0002] After the tebuconazole suspension is processed into products, it is not very stable. Most of them will have stratification, agglomeration and content degradation within half a year, resulting in ineffective or even unusable products. Therefore, the additives in the product formula Choice is very important. After many times of debugging and development, and through many experiments, we successfully invented a formula for producing 430g / l tebuconazole suspension concentrate. The invention of this formula overcomes the stratification, agglomeration and content of the product by selecting appropriate additives. Degra...
