Example Embodiment

[0020] Example 1 (25% thiafluzamide·hexaconazole oil suspension)

[0021] The following substances are all weight percentages: Thiofuamide 24%, hexaconazole 1%, fatty alcohol polyoxyethylene ether 5%, Nongru 602#4%, sodium lignin sulfonate 10%, styrylphenol polyoxyethylene Ether 3%, methyl cellulose 3%, epoxidized soybean oil 1%, glycerol 0.5%, xanthan gum 2%, the balance is castor oil. The above formula is sequentially added to the grinding kettle for grinding according to the proportion, and then put into a homomixer and mixed to obtain a 25% thiafluzamide·hexaconazole oil suspension.

Example Embodiment

[0022] Example 2 (20% Thiofuamide·Hexiconol Suspension Concentrate)

[0023] The following substances are percentages by weight: 18% thifluzamide, 2% hexaconazole, 4% fatty alcohol polyoxyethylene ether, 5% calcium dodecylbenzene sulfonate, tristyrylphenol polyoxyethylene polyoxypropylene Ether 3%, epoxidized soybean oil 1%, sorbitol 0.5%, and the balance is castor oil. The above formula is pulverized in advance according to the proportion, and then added to a sand mill for grinding, and after high shear mixing, a 20% thiafluzamide·hexaconazole suspension is prepared.

Example Embodiment

[0024] Example 3 (15% thiafluzamide·hexaconazole water emulsion)

[0025] The following substances are in weight percentage: thiafluzamide 12%, hexaconazole 3%, N-methylpyrrolidone 5%, Nongru 500#4%, calcium dodecylbenzene sulfonate 5%, sodium chloride 1% , Glycerin 0.5%, aluminum magnesium silicate 1%, gum arabic 2%, the balance is deionized water. Dissolve the original medicine, solvent, and emulsifier in the above formula into a uniform oil phase; mix the water-soluble components in the formula and deionized water to prepare a water phase; under high-speed stirring, mix the oil and water phases to prepare 15% thiol Furamide·hexaconazole water emulsion.

Abstract

The invention discloses a pesticide compound containing thifluzamide and hexaconazole, and the application thereof; the compound comprises commonly used additive, thifluzamide and hexaconazole; and the weight part ratio of the thifluzamide to the hexaconazole is 24:1 to 1:1, and the weight percentage of the total weight of the thifluzamide and the hexaconazole is 5 to 80 percent. The invention isapplicable in preventing plant diseases in agriculture, particularly applicable in preventing rice sheath blight. The prevention effect of the invention has significant synergic effect than the single dose, and the invention reduces the used dose of the pesticide, reduces the medication cost, prolongs the service life of the preparation and reduces the adverse impact of the pesticide on the ecological environment.

Description

technical field [0001] The pesticide composition involved in the present invention uses thifuramide and hexaconazole as active ingredients, and is used for preventing and treating agricultural plant diseases, especially rice sheath blight. Background technique [0002] During the growth and development of crops, they are susceptible to various diseases, especially fungal diseases, which are of many types and cause serious damage. For a long time, chemical control has been the main effective means of disease control. However, in recent years, due to monotherapy and unscientific drug use, many pathogenic bacteria have developed resistance to the currently used pesticides. Rice sheath blight is one of the main diseases of rice, which commonly occurs in rice-growing countries such as Asia, America, and Africa. It is distributed in all rice areas in my country, but it is common in rice areas south of the Yangtze River, and can occur in early, middle, and late rice, causing a sig...
