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.

Abstract

The invention relates to the field of herbicides, and particularly relates to an herbicidal composition, application thereof and an herbicide and a preparation method thereof. The herbicidal composition comprises an organic heterocyclic compound, an s-triazine compound and an amide compound, wherein the mass ratio of the organic heterocyclic compound to the s-triazine compound to the amide compound is 1-10:5-60:2-60, preferably 1:4-8:15-30, and most preferably 1:5:20. According to the compounding of the organic heterocyclic compound, the s-triazine compound and the amide compound, various weeds in annual crops can be removed, and the weeding spectrum of the herbicide is improved; meanwhile, according to the compounding, the weeding efficiency of the herbicidal composition is improved, thedosage of the herbicidal composition is reduced, the influence of multiple crops of the herbicidal composition is reduced, and the normal growth of the crops is ensured.

Description

technical field [0001] The present invention relates to the field of herbicides, and in particular to a herbicide composition, its application, herbicide and its preparation method. Background technique [0002] During the growth of crops, weeds will inevitably exist and affect their normal growth, so it is necessary to use herbicides to remove weeds, and herbicides are generally chemical reagents with phytotoxicity, which will affect the normal growth of crops or their impact value, or general weeding Herbicides can only remove one or a certain type of weeds, and the herbicide effect is poor. At the same time, in order to ensure the herbicide effect, the general use of herbicides is large, which further aggravates the impact of herbicides on crops. Contents of the invention [0003] The object of the present invention is to provide a herbicidal composition, which has a large herbicidal spectrum and can simultaneously remove various weeds. At the same time, the herbicidal ...
