Embodiment 1

[0011] Example 1 : 20% Thiofuramide · Fluazinam Suspending Concentrate.

[0012] Thiofuramide 6%, Fluazinam 14%, Tristyrylphenol polyoxyethylene polyoxypropylene ether 3%, Calcium dodecylbenzenesulfonate 3%, Alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 2%, ethylene glycol 0.2%, xanthan gum 0.1%, silicone 0.4%, glycerin 5%, gum arabic 0.1%, deionized water to make up to 100%. The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then mixed by high shear to prepare a 20% thifuramide · fluazinam suspension concentrate. Use 12 grams per mu of 20% Thiofuramide Fluazinam Suspension Concentrate, and spray with water at the early stage of potato late blight, and the control effect is 85.5% after 7 days; gram, 5% fluazinam suspending agent mu with 40 grams of spraying by the same method, 7 days after the control effect was 81.1%, 75.6%.

Embodiment 2

[0013] Example 2 : 60% Thiofuramide · Fluazinam Water Dispersible Granules.

[0014] Thiofuramide 20%, Fluazinam 40%, Sodium Lauryl Sulfate 6%, Polycarboxylate 4%, Sodium Chloride 2%, Polyethylene Glycol 3%, Soluble Starch 3%, Kaolin to 100% . The above formula is dry crushed in proportion, granulated, dried and sieved to prepare 60% Thiofuramide·fluazinam water dispersible granules. Use 60% Thiofuramide · Fluazinam water-dispersible granules, 6 grams per mu, spray with water at the early stage of the onset of Botrytis cinerea, and the control effect is 90.3% after 7 days; the control single agent 24% Thiofuramide suspension 15 grams per mu and 40 grams of 5% fluazinam suspending agent per mu were applied in the same way, and the control effects were 84.4% and 80.7% after 7 days.

Embodiment 3

[0015] Example 3 : 40% Thiofuramide · Fluazinam wettable powder.

[0016] Thiofuramide 10%, fluazinam 30%, pull open powder 3%, naphthalene sulfonate formaldehyde condensate 6%, talcum powder 15%, kaolin make up to 100%. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 40% Thiofuramide·fluazinam wettable powder. Use 12 grams of 40% Thiofuramide Fluazinam wettable powder per mu, and spray it with water at the early stage of cabbage clubroot disease, and the control effect is 94.2% after 7 days; the control single dose of 24% Thiofuramide Suspending Agent Mu With 15 grams, 5% fluazinam suspension concentrate and 40 grams per mu, the same method was used to apply the pesticides, and the control effects were 70.2% and 85.1% after 7 days.

Abstract

The invention discloses a bactericide composition of thifluzamide and fluazinam. The bactericide composition comprises common accessory ingredient, thifluzamide and fluazinam, wherein the mass fraction ratio of the thifluzamide to the fluazinam is (10 to 1) to (1 to 15), and the preferred ratio is (6 to 1) to (1to 9). After the thifluzamide and the fluazinam are compounded, the effect is improved remarkably, and the dosage of the effective components of compounded medicament is less than that of the effective components used separately, so that the bactericide composition is suitable for preventing and curing diseases caused by plant pathogens, such as phytophthora infestans, plasmodiophoromycetes and botrytis cinerea.

Description

technical field [0001] The fungicidal composition of the present invention uses thifuramide and fluazinam as active ingredients, and is suitable for preventing and treating diseases caused by plant pathogens such as Phytophthora infestans, Root Phytophthora, Botrytis cinerea, and Sclerotinia sclerotiorum. Background technique [0002] Thiofuramide, English common name: thifluzamide, chemical formula C 13 h 6 Br 2 f 6 N 2 o 2 S, chemical name 2,6-dibromo-2-methyl-4-trifluoromethoxy-4-trifluoromethyl-1,3-thiazole-5-carbonanilide, belongs to thiazole amide fungicides , with strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor. [0003] Fluazinam, English common name: fluazinam, chemical name 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-di Nitro-p-toluidine. Fluazinam is a protective fungicide, the current commercial formulation is suspension concentrate, and the main method of application is...
