Embodiment 1

[0012] 1. The formula of oil suspension agent a: Atrazine original powder 30%, butachlor crude oil 51.5%, emulsifier 10%, vegetable oil balance. The proportioning ratio (weight ratio) of the two active ingredients of the product is: atrazine:butachlor=1:1.72.

[0013] 2. The preparation method of oil suspension a: according to the ratio of pesticides in the active ingredients, weigh a certain amount of atrazine raw powder and butachlor crude oil respectively and put them into a high-pressure homogenizer; then add quantitative emulsifier and Vegetable oil; co-grinding to make a milky white oil suspension with good fluidity a.

[0014] Accompanying drawing 1 is the process flow sheet of oil suspending agent a.

Embodiment 2

[0016] 1. The formula of oil suspension agent b: 30% of atrazine powder, 51.5% of acetochlor crude oil, 10% of emulsifier, and the balance of vegetable oil. The proportioning ratio (weight ratio) of the two active ingredient pesticides of the product is: atrazine:acetochlor=1:1.72.

[0017] 2. The preparation method of oil suspension b: according to the ratio of pesticides in the active ingredients, weigh a certain amount of atrazine raw powder and acetochlor crude oil respectively and put them into a high-pressure homogenizer; then add quantitative emulsifier and Vegetable oil; co-grinding to make a milky white oil suspension with good fluidity b.

Abstract

An oily suspension of herbicide for corn is prepared from atrazine powder, butachlor oil, acetochlor oil, propisochlor oil, emulsifier, and plant oil through proportioning, and high-pressure grinding to obtain three kinds of product. Its advantages are high effect, high safety, and no residue.

Description

technical field [0001] The invention belongs to the field of pesticide mixing and formulation processing, in particular to a special herbicide for corn fields, an oil suspension and a preparation method thereof. Background technique [0002] At present, no matter at home or abroad, there are many herbicide products for corn fields, including single agent products and compound products; The normal growth of corn has increased the yield, reduced the labor burden and increased farmers' income. But existing these products all still exist some defectives to need to solve: the one, the residual period of single-dose product is long, and next stubble crop is harmful; Herbicidal spectrum is narrow, and effect is limited; Adverse effects; the second is that the content of active ingredients in the compound product is low, and the effect is poor; the dosage is large and the cost of use is high. [0003] The purpose of the present invention is to develop a speci...
