Problems solved by technology

[0002] During the growth of crops, there will inevitably be weeds that 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.

preparation example Construction

[0031] The present invention also provides a preparation method of the above-mentioned herbicide, comprising 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, organic heterocyclic compounds, s-triazine compounds and amide compounds are weighed according to the ratio with Nongru 1601, silicone defoamer, xanthan gum, ethylene glycol Alcohol and water are mixed, stirred and sheared, and then ground in a sand mill after stirring, so that the D50 of the ground material shall not be greater than 8 microns, and finally the ground material is added to a shearing kettle and sheared for 30 minutes; the target product is obtained . In the process of mixing with substances such as xanthan gum, inorganic bentonite can also be supplemented.

[0033] For example, the herbicide is prepared as a wettable powder, ...

Embodiment 1

[0041] This embodiment provides a herbicidal composition, which comprises isoxaflutole, promezam and acetochlor, and the mass ratio of isoxaflutole, promezam and acetochlor is 1:5:20.

[0042] This embodiment also provides a herbicide, the herbicide is a suspoemulsion, which includes the above-mentioned herbicidal composition, and the mass percentage content of the herbicidal composition is 78% (isoxaflutole 3%+promazone 15%+ Acetochlor 60%).

[0043] This example also provides a preparation method of a herbicide: specifically, 78% herbicidal composition (isoxaflutole 3% + promethazone 15% + acetochlor 60%), Nongru 16016%, organic 1.5% silicon defoamer, 0.03% xanthan gum, 2% ethylene glycol, and the balance is water. Add it to the stirring tank, stir it fully and cut it for 30 minutes, and then grind it in the sand mill after stirring, so that after grinding The D50 of the material must not be greater than 8 microns, and finally the ground material is added to the shearing ke...

Embodiment 2

[0044] Embodiment 2: the acetochlor of embodiment 1 is replaced with alachlor; All the other are with embodiment 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 ...
