Embodiment 1

[0014] Its components and weight percentages are as follows:

[0015]

[0016] Using the rotary disc granulation method. Fully mix 2,4-D dimethylamine salt, penetrant T and ammonium sulfate to prepare 2,4-D dimethylamine salt soluble powder, then add 2,4-D dimethylamine salt to the inclined rotating disk The amine salt soluble powder is sprayed into the soluble starch aqueous solution for granulation, and the obtained granules are dried to obtain 2,4-D dimethylamine salt soluble granules.

Embodiment 2

[0018] Its components and weight percentages are as follows:

[0019]

[0020] Using screw extrusion granulation method. Thoroughly mix 2,4-D dimethylamine salt, sodium sulfate, and azone, transfer them to a mixer, spray into an aqueous solution of polyethylene glycol, and mix thoroughly. The obtained material is granulated and dried to obtain 2,4-D dimethylamine salt soluble granules.

Embodiment 3

[0022] Its components and weight percentages are as follows:

[0023]

[0024]

[0025] Using screw extrusion granulation method. Mix all the above-mentioned components thoroughly, transfer to a screw extrusion granulator to granulate, that is, 2,4-D dimethylamine salt soluble granules.

Abstract

The invention discloses a 2,4-D dimethylamine salt soluble granule which comprises the following components in percentage by weight: 10-98 percent of 2,4-D dimethylamine, 0.1-15 percent of an adhesive, 0.1-5 percent of a synergist and the balance being filler. A preparation method for the 2,4-D dimethylamine salt soluble granule comprises the following steps of mixing 10-98 percent of the 2,4-D dimethylamine, 0.1-15 percent of the adhesive, 0.1-5 percent of the synergist and the residual filler for granulation, and drying granulated granules. The preparation method is reliable; the obtained 2,4-D dimethylamine salt soluble granule is high in particle strength and high in dissolve dispersion performance; compared with a 2,4-D dimethylamine salt water agent, the 2,4-D dimethylamine salt soluble granule has the advantages of convenience in use and transportation and safety and stability in storage.

Description

technical field [0001] The invention relates to a pesticide herbicide and a preparation method thereof, in particular to a soluble granule of 2,4-D dimethylamine salt and a preparation method thereof. Background technique [0002] 2,4-D, also known as 2,4-D acid, (2,4-dichlorophenoxy)acetic acid, 2,4-D, 2,4-dichlorophenoxyacetic acid, it is an option It is a strong systemic transduction hormone herbicide, which has poisonous effect when used in high concentration, so it is widely used in the prevention and treatment of gramineous crops such as rice, corn, wheat, barley, oats, pasture, sorghum, and sugarcane. Eliminate annual and perennial broadleaf weeds, sedges and some vicious weeds. [0003] At present, the main dosage forms of 2,4-D are ester emulsifiable concentrate, amine salt solution, and sodium salt soluble powder. Among them, 2,4-D dimethylamine saline solution is the most widely produced and used. However, high-content 2,4-D dimethylamine saline solution, such ...
