Problems solved by technology

[0002] The current formulations of powders, emulsifiable concentrates, wettable powders, granules, and suspensions all have the disadvantage of being difficult to use. For example, before use, they must be diluted with soil or water and spread or sprayed in the field, which is labor-intensive and time-consuming. , labor-intensive, usually using poisonous soil or spraying pesticides takes 1.2 hours / mu
In addition, powders, wettable powders, and emulsifiable concentrates have many disadvantages as follows, such as powder dust that affects the health of producers and users; powders, wettable powders, and emulsifiable concentrates drift during production and use Pollution to the surrounding environment; the organic solvent contained in the emulsifiable concentrate is harmful to humans, livestock, natural enemies, microorganisms, etc., pollutes water sources and aquatic organisms, and is not friendly to the environment.
[0003] Although environmental protection dosage forms such as water-based and water-dispersible solids have developed rapidly in recent years, these dosage forms are not labor-saving when used, because the labor-intensive and labor-intensive application of the spray method and the poisonous soil method cannot be solved. Methods and cleaning equipment and other issues
Although large granules and effervescent products are convenient to use, large granules often cause phytotoxicity due to high production costs and uneven distribution of chemicals in paddy fields; effervescent products are prone to neutralization reactions due to the acid and alkali substances in the drugs And make the product invalid, not easy to save
Therefore, large granule and effervescent formulations have been unsuccessfully promoted for many years

Embodiment 1

[0018] 25 parts of pyrazosulfuron-methyl, 6 parts of lignosulfonate sulfate (purchased from Takemoto), 2 parts of polyethylene glycol and 3 parts of sodium hexametaphosphate (purchased from Jiangsu Yixing Auxiliary Factory) were mixed in a double-helix mixer Mix in 30 minutes, drop into the kneader together with 59 parts of hollow glass beads after being pulverized by a jet mill, then drop into 5 parts of fatty acid ethylene glycol ester (CH-8000, purchased from Takemoto company) and 20 parts of water, knead for 15 After -30 minutes, use an extrusion granulator to granulate, dry in a hot air circulation drying oven (temperature ≤ 60°C), sieve and pack after sampling and testing pass.

Embodiment 2

[0020] 1 part of pyrazosulfuron-methyl, 28 parts of quinclorac, 4 parts of sodium hexametaphosphate (purchased from Jiangsu Yixing Auxiliary Factory), 7 parts of lignosulfonate sulfate (purchased from Takemoto Company) and 2 parts of poly Ethylene glycol was mixed with a double-screw mixer for 30 minutes, pulverized by a jet mill and put into a kneader together with 51 parts of hollow glass beads, and then dropped into 7 parts of fatty acid ethylene glycol esters (CH-8000, purchased from Takemoto company) and 19 parts of water, kneaded for 30 minutes, granulated with an extrusion granulator, dried in a fluidized bed (air inlet temperature ≤ 90° C.), sieved and packaged after passing the test.

Embodiment 3

[0022] Mix 1 part of pyrazosulfuron-methyl, 25 parts of mefenamide, 3 parts of sodium tripolyphosphate (purchased from Jiangsu Yixing Auxiliary Factory), 7 parts of lignosulfonate sulfate and 3 parts of sucrose in a double-helix mixer Mix for 30 minutes, drop into the kneader together with 54 parts of hollow glass beads after being pulverized by a jet mill, then drop into 7 parts of fatty acid ethylene glycol esters (CH-8000, purchased from Takemoto company) and 19 parts of water, and knead for 30 minutes Finally, granulate with an extrusion granulator, dry in a fluidized bed (air inlet temperature ≤ 90°C), sieve and pack after passing the test.

Abstract

The invention relates to a water surface expansion granule which can float on the water surface, automatically disperse and expand, and is used in rice fields and characterized in that the water surface expansion granule is composed of the following components through parts by weight: 1.0 to 50 parts of weedicide active ingredient, 0.1 to 30 parts of water surface expanding agent, 5 to 99 parts of light carrier, 0.1 to 30 parts of surfactant, 0.1 to 20 parts of stabilizing agent, and 0 to 10 parts of caking agent.

Description

technical field [0001] The invention relates to a new formulation of pesticide processing used in paddy fields. More specifically, the present invention relates to a paddy field water surface expanding granule that can float on the water surface and automatically disperse and expand on the water surface. The present invention further relates to a preparation method of the water surface expanding granule. Background technique [0002] The current formulations of powders, emulsifiable concentrates, wettable powders, granules, and suspensions all have the disadvantage of being difficult to use. For example, before use, they must be diluted with soil or water and spread or sprayed in the field, which is labor-intensive and time-consuming. , labor-intensive, usually using poisonous soil or spraying pesticides takes 1.2 hours / mu. In addition, powders, wettable powders, and emulsifiable concentrates have many disadvantages as follows, such as powder dust that affects the health...
