Example Embodiment
[0031] The present invention also provides a preparation method of the above herbicide, which includes the following steps: mixing organic heterocyclic compounds, s-triazine compounds and amide compounds with auxiliary materials and preparing them.
[0032] Specifically, for example, when the herbicide is prepared as a suspoemulsion, the organic heterocyclic compound, s-triazine compound, and amide compound are weighed according to the ratio of Nongru 1601, silicone defoamer, xanthan gum, and ethylene dichloride. Alcohol and water are mixed and stirred for shearing. After stirring, they are ground in a sand mill so that the D50 of the ground material shall not be greater than 8 microns. Finally, the ground material is added to the shearing kettle and cut for 30 minutes; the target is obtained . In the process of mixing with xanthan gum and other substances, inorganic bentonite can also be added.
[0033] For example, the herbicide is prepared as a wettable powder, and the organic ...
Example Embodiment
[0040] Example 1
[0041] This embodiment provides a herbicidal composition comprising isoxaflutole, promethacin and acetochlor, and the mass ratio of isoxaflutole, promethacin and acetochlor is 1:5:20.
[0042] This embodiment also provides a herbicide, the herbicide is a suspoemulsion, which comprises the above herbicidal composition, the mass percentage content of the herbicidal composition is 78% (isoxaflutole 3% + promethazine 15% + Acetochlor 60%).
[0043] This embodiment also provides a preparation method of a herbicide: specifically, 78% of the herbicidal composition (isoxaflutole 3% + promethacin 15% + acetochlor 60%), agricultural milk 16016%, organic Silicon defoamer 1.5%, xanthan gum 0.03%, ethylene glycol 2%, and the remainder is water. Add water into the stirred tank and fully stir and shear for 30 minutes. After stirring, grind in a sand mill to make The D50 of the material should not be greater than 8 microns. Finally, the ground material is added to the shearing k...
Example Embodiment
[0044] Example 2: The acetochlor in Example 1 was replaced with alachlor; the rest were the same as in Example 1.
