Embodiment 1

[0036] Example 1 : Based on the total weight of the granules, active ingredients thiazophosphine 10%, hymexazol 0.2%, dispersing aid corn starch 0.5%, slow-release agent polyvinyl alcohol 0.1%, binder polyethylene glycol 0.1%, carrier A mixture of 70% attapulgite particles, the balance filler calcium bicarbonate and white kaolin.

[0037] According to the preparation method of the granule of the present invention, thiazolyl, hymexazol, dispersing aid, and slow-release agent are uniformly metered and mixed, and the attapulgite particles are used for adsorption to obtain a carrier material, which is inspected and used after passing the test, and the cause of failure is analyzed Formulate a plan for re-adsorption, and use it after passing the test; mix the filler, dispersing aid, and binder evenly to prepare the coating material for use, and finally use the coating method to granulate the carrier material and coating material. Dry at 110°C to 120°C until the water content of th...

Embodiment 2

[0038] Example 2: Based on the total weight of the granules, active ingredients thiazophosphine 8%, hymexazol 0.2%, dispersing aid corn starch 0.5%, slow-release agent polyvinyl alcohol 0.1%, binder polyethylene glycol 0.1%, carrier A mixture of 80% attapulgite particles, the balance filler calcium bicarbonate and white kaolin.

[0039] According to the preparation method of the granule of the present invention, thiazolyl, hymexazol, dispersing aid, and slow-release agent are uniformly metered and mixed, and the attapulgite particles are used for adsorption to obtain a carrier material, which is inspected and used after passing the test, and the cause of failure is analyzed Formulate a plan for re-adsorption, and use it after passing the test; mix the filler, dispersing aid, and binder evenly to prepare the coating material for use, and finally use the coating method to granulate the carrier material and coating material. Dry at 110°C to 120°C until the water content of the ...

Embodiment 3

[0040] Example 3 : Based on the total weight of the granules, active ingredients thiazophosphine 15%, hymexazol 0.4%, dispersing aid corn starch 0.5%, slow-release agent polyvinyl alcohol 0.1%, binder polyethylene glycol 0.1%, carrier A mixture of 80% attapulgite particles, the balance filler calcium bicarbonate and white kaolin.

[0041] According to the preparation method of the granules of the present invention, thiazolyl, hymexazol, dispersing aids, and slow-release agents are uniformly metered and mixed, and the attapulgite particles are used for adsorption to obtain a carrier material, which is inspected and used after passing the test, and the reason for failure is analyzed Formulate a plan for re-adsorption, and use it after passing the test; mix the filler, dispersing aid, and binder uniformly to prepare the coating material for use, and finally use the coating method to granulate the carrier material and coating material. Dry at 110°C to 120°C until the water conte...

Abstract

The invention relates to a fosthiazate and hymexazol granule. The fosthiazate and hymexazol granule comprises the following components in percentage by weight: 0.1-20% of fosthiazate, 0.1-5% of hymexazol, 60-80% of a carrier attapulgite grain, 0.5-3% of a dispersing auxiliary agent, 0.1-2% of a slow release agent, 0.1-5% of a bonding agent and residual fillers. The invention further discloses a preparation method of the fosthiazate and hymexazol granule; and the fosthiazate and hymexazol granule effectively combines the effects of preventing and treating plant nematode diseases and soil borne diseases, efficiently, scientifically and reasonably utilizes resources, has very important meanings on protecting an environment, and has the active propelling effects of reducing the agricultural input and increasing both production and income of agriculture.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to thiazophosphine and hymexazol granules and a preparation method thereof, which are mainly used for preventing and treating soil-borne diseases caused by pathogenic fungi and nematodes caused by pathogenic nematodes. Background technique [0002] Fusarium ( Fusarium ) Also known as Fusarium, saprophytic, weakly parasitic or parasitic, causing wilting, rot and other symptoms. For example, Fusarium oxysporum causes soybean root rot, and various specialized types of Fusarium oxysporum cause wilt of different plants. Fusarium oxysporum is a typical soil-dwelling bacterium, which can survive chlamydospores in the soil or diseased debris for 5-6 years. Fusarium oxysporum is spread in the field mainly through agricultural operations, rain, underground pests, nematodes, etc. , and can also be spread over long distances through infected seeds and seedlings. This kind of disease is easy to be p...
