Problems solved by technology

[0002] 2,4-D isooctyl ester is a contact-killing herbicide for post-emergence stem and leaf treatment. It belongs to the phenoxyacetic acid class of herbicides. It can be absorbed and conducted by plant roots, stems and leaves. The absorption of stems and leaves can be through the plant The bark conducts downward to reach the whole plant, but the whole plant is severely deformed and destroys the physiological functions of the plant, leading to death

Embodiment 1

[0012] This example is a 2,4-D isooctyl mixed herbicide, including the following components in mass ratio, 2,4-D isooctyl 55%, butachlor 15%, nicosulfuron 2%, chloropyr Sensitive 3%, emulsifier 5%, anionic surfactant 2%, aromatic solvent naphtha 18%.

[0013] Wherein, the solute percentage of 2,4-D isooctyl ester is 96%.

[0014] The emulsifier is selected from the Berol 9960 / 9968 mixture manufactured by AkzoNobel.

[0015] In the preparation process of water suspension, the melting point of the original drug is low, and the dispersant with low critical micelle concentration has a good effect on inhibiting the crystal growth, but the pure anionic dispersant is not enough to control the dispersion stability of the system. It is necessary to add a non-ionic macromolecular emulsifier to stabilize the dispersion system. Adding a non-ionic block copolymer dispersant can have a good stabilizing effect and solve the problem of crystal growth.

[0016] The anionic surfactant is sodi...

Embodiment 2

[0020] The difference from Example 1 is that this example includes the following components in mass ratio, 2,4-D isooctyl ester 60%, butachlor 10%, nicosulfuron 6%, chlorachlor 1%, emulsifier 7%, anionic surfactant 1%, aromatic solvent naphtha 15%.

Embodiment 3

[0022] The difference from Example 1 is that this example includes the following components in mass ratio, 57% of 2,4-D isooctyl ester, 13% of butachlor, 4% of nicosulfuron-methyl, 2% of chlorchlorazine, emulsifier 6%, anionic surfactant 1.5%, aromatic solvent naphtha 16.5%.

[0023] The test results of 2,4-D isooctyl ester mixed herbicide are as follows:

[0024]

[0025]

[0026] Shown by the data in the table above, embodiment 2 has better emulsion stability compared with embodiment 1 or embodiment 3, and embodiment 1 has better weed suppression cycle performance than embodiment 2 or embodiment 3, comprehensive comparison Excellent beneficial effects The effect of Example 3 is more prominent than that of Example 1 and Example 2.

[0027] Among them, in Example 3, due to the fixed ratio of each raw material in the herbicide, the control of the anionic surfactant is reflected in the control range of the pH value, and at the same time, due to the ratio of 2,4-D isooctyl...

Abstract

The invention discloses a 2,4-D isooctyl ester mixed herbicide which comprises the following components in percentage by mass: 55-60 percent of 2,4-D isooctyl ester, 10-15 percent of butachlor, 2-6 percent of nicosulfuron, 1-3 percent of chlorfenapyr, 5-7 percent of an emulsifier, 1-2 percent of an anionic surfactant and the balance being aromatic solvent oil. According to the invention, the preparation with lasting pesticide effect for preventing weed regeneration is prepared.

Description

technical field [0001] The invention belongs to the technical field of herbicides, in particular to a 2,4-D isooctyl ester mixed herbicide. Background technique [0002] 2,4-D isooctyl ester is a contact-killing herbicide for post-emergence stem and leaf treatment. It belongs to the phenoxyacetic acid class of herbicides. It can be absorbed and conducted by plant roots, stems and leaves. The absorption of stems and leaves can be through the plant The bark conducts downward to reach the whole plant, but the whole plant shows serious deformity and destroys the physiological function of the plant, leading to death. The targets for control and control are generally: annual or perennial broad-leaved weeds such as weeds, bermudagrass, quince, solanum nigrum, and ion grass. How to use the chemical agent of 2,4-D isooctyl ester to achieve the effect of killing weeds with the lowest dose, so it is necessary to prepare a preparation with long-lasting drug effect to prevent the rebirt...
