Chlorimuron-ethyl soluble water particulate agent and preparation method thereof

Abstract

The invention discloses a chlorimuron-ethyl soluble water particulate agent and a preparation method thereof. The chlorimuron-ethyl soluble water particulate agent comprises the following components by weight percent: 15 to 90 percent of chlorimuron-ethyl raw medicine, 1 to 10 percent of dispersing agent, 1 to 7 percent of salt forming agent, 1 to 5 percent of disintegrating agent, 0 to 3 percent of water and the balance of filler. The chlorimuron-ethyl soluble water particulate agent and the preparation method disclosed by the invention have the advantages that the preparation process is simple, the production cost is low, equipment or a special production process does not need to be added, and the pollution to the environment is less; since the specific salt forming agent is selected, the chlorimuron-ethyl soluble water particulate agent can be rapidly dispersed and uniformly dissolved in water, is less in use amount, good in weed killing effect, low in drug damage and high in crop yield; the dispersion is more uniform in diluted aqueous solution, a spraying nozzle is not blocked in use, the preparation is more environmental friendly, the cost is low, the packaging requirement is low, the use is convenient and the chlorimuron-ethyl soluble water particulate agent is suitable for large-area promotion.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a chlorimuron-methyl soluble water granule and a preparation method thereof. Background technique [0002] Chlorsulfuron-methyl chemical name: α-[(4-chloro-6-methoxypyrimidine-2) aminocarbonyl] ethyl aminobenzoate is a high-efficiency, broad-spectrum, systemic sulfonylurea soybean field Selective pre-emergence and post-emergence herbicide. It can be absorbed by plant roots, stems and leaves, conduct up and down transmission in plants, and mainly accumulate in plant meristems. Its mechanism of action is to inhibit the biosynthesis of amino acids, and can quickly control the growth of sensitive weeds. When spraying after emergence, The leaves of sensitive plants will lose their chlorosis in 3-5 days, and the growth points will be necrotic. In 7-21 days, the weeds will gradually die. Soy can metabolize it into inactive substances. Mainly used in soybean fields to control bro...

Problems solved by technology

[0004] Water granules cannot disintegrate and dissolve quickly after entering water, and the speed is slow. Secondary dissolution is required to disperse to form a granular dosage form of suspension. The utilization rate of active ingredients is low. Generally, the utilization rate of active ingredients is about 70%.

Patent CN98113985.X provides a chlorimuron-methyl soluble powder and its preparation method, which requires the original drug of chlorimuron-methyl to be reacted into an organic salt, and a large amount of solvents such as dichloroethane are required for production, which is highly toxic and complicated in the production process. Aggravated environmental pollution, increased production costs, low safety factor, and CN98113985.X is made of powder preparation, the state of matter is equivalent to wettable powder

In addition to herbicides containing chlorimuron-methyl, there is no dosage form with a higher utilization rate of active ingredients
