Embodiment 1

[0022] Embodiment 1 (12% Thiofuramide Difenoconazole Oil Suspension Concentrate)

[0023] The following substances are all percentages by weight: Thiofuramide 10%, Difenoconazole 2%, Fatty Alcohol Polyoxyethylene Ether 5%, Agricultural Milk 600# 4%, Calcium Dodecyl Sulfonate 4%, Styryl 3% phenol polyoxyethylene ether, 3% methyl cellulose, 1% epoxidized soybean oil, 0.5% glycerin, 1% xanthan gum, and the balance is castor oil. Add the above formulations in proportion to the grinding kettle in turn for grinding, put them into a homomixer and mix evenly to prepare 12% Thiofuramide·Difenoconazole Oil Suspension Concentrate.

Embodiment 2

[0024] Embodiment 2 (10% Thiofuramide Difenoconazole Suspension Concentrate)

[0025] The following substances are all percentages by weight: Thiofuramide 7.5%, Difenoconazole 2.5%, Nonylphenol Polyoxyethylene Ether 2%, Alkylphenol Polyoxyethylene Ether Polyoxypropylene Ether Block Copolymer 2%, Poly Vinyl alcohol 1%, ethylene glycol 5%, epoxidized soybean oil 1%, sorbitol 0.5%, and the balance is deionized water. The above formula is pre-crushed according to the proportion, and then put into a sand mill for grinding, and then prepared after high-shear mixing to prepare 10% Thiofuramide·Difenoconazole Suspension Concentrate.

Embodiment 3

[0026] Example 3 (15% Thiofuramide Difenoconazole Water Emulsion)

[0027] The following substances are all percentages by weight: Thiofuramide 7.5%, Difenoconazole 7.5%, N-Methylpyrrolidone 8%, Nongru 600#4%, Calcium dodecylbenzenesulfonate 5%, Glycerin 0.5% , magnesium aluminum silicate 1%, gum arabic 2%, and the balance is deionized water. Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix the water-soluble components in the formula with deionized water to obtain a water phase; Furamide Difenoconazole Water Emulsion.

Abstract

The invention discloses a pesticide composition containing thifluzamide and difenoconazole and an application thereof. The pesticide composition comprises a common auxiliary agent, the thifluzamide and the difenoconazole, wherein the ratio in part by weight of thifluzamide to the difenoconazole is 10:1-1:10; and the pesticide composition comprises 5 to 80 percent by weight of the thifluzamide and the difenoconazole. The pesticide composition of the invention is suitable for preventing and treating crop diseases and is particularly suitable for preventing and treating fungal diseases, such as rice sheath blight, rice blast, rice false smut and the like. Compared with the control effect of a single dose, the control effect of the composition has obvious synergistic action. Moreover, the composition reduces dosage of a pesticide, reduces dosage cost, prolongs the service life of the pesticide and reduces adverse effects of the pesticide on the ecological environment.

Description

technical field [0001] The pesticide composition involved in the present invention uses thifuramide and difenoconazole as active ingredients, and is used for preventing and treating crop diseases, especially fungal diseases such as rice sheath blight, rice blast, and rice false smut. Background technique [0002] During the growth and development of crops, they are susceptible to various diseases, especially fungal diseases, which have many types and cause serious damage. Rice sheath blight, rice blast, and rice false smut are important fungal diseases of rice. They occur in various rice-producing areas in my country. They occur in a large area, are highly prevalent, and cause serious damage, resulting in reduced rice production, and even crop failure in severe cases. [0003] For a long time, chemical control has been the main effective means of controlling crop diseases. At present, the main agents used to prevent and control rice fungal diseases such as rice sheath bligh...
