Embodiment 1

[0014] Example 1: 81% fluthiazolidone·syringstrobin water-dispersible granules (fluthiazolidone:syringstrobin = 80:1)

[0015] Made according to the conventional process, wherein fluthiapiprofen 80g, syringstrobin 1g, naphthalenesulfonate NNO (diffusion agent) 4g, sodium lignosulfonate (dispersant) 10g, sodium lauryl sulfate (wetting agent) agent) 3g, kaolin (filler) to make up to 100g.

[0016] In this example, the mass ratio of fluthiazolidin and syringstrobin can vary between 80:1 and 1:80, and the total mass percentage of the two can vary between 5% and 85%. The proportioning of agent also is adjusted correspondingly thereupon, forms new embodiment.

Embodiment 2

[0017] Example 2: 41% fluthiapiprofen·syringstrobin wettable powder (fluthiapiprofen:syringstrobin = 40:1)

[0018] Made according to the conventional process, wherein fluthiazolin 40g, syringstrobin 1g, sodium lauryl sulfate (wetting agent) 2g, naphthalenesulfonate NNO (diffusion agent) 5g, sodium lignosulfonate (dispersant) agent) 6g, kaolin supplemented to 100g.

[0019] In this example, the mass ratio of fluthiazolidin and syringstrobin can vary between 80:1 and 1:80, and the total mass percentage of the two can vary between 5% and 85%. The proportioning of agent also is adjusted correspondingly thereupon, forms new embodiment.

Embodiment 3

[0020] Example 3: 21% fluthiapiprofen·syringstrobin suspension concentrate (fluthiapiprofen:syringstrobin = 20:1)

[0021] Made according to the conventional process, wherein fluthiazolin 20g, syringstrobin 1g, sodium lignosulfonate (dispersant) 4g, ethylene glycol (antifreezing agent) 4g, organosilicone (defoamer) 0.4g , sodium lauryl sulfate (wetting agent) 3g, bentonite (thickener) 0.2g, deionized water to make up to 100g.

[0022] In this example, the mass ratio of fluthiazolidin and syringstrobin can vary between 80:1 and 1:80, and the total mass percentage of the two can vary between 5% and 85%. The proportioning of agent also is adjusted correspondingly thereupon, forms new embodiment.

Abstract

The invention discloses a fungicidal composition. Effective ingredients of the fungicidal composition comprise oxathiapiprolin and coumoxystrobin, the mass ratio of oxathiapiprolin to coumoxystrobin is 80:1 to 1:80, and the preferred mass ratio is 20:1 to 1:20. An obvious synergistic effect is achieved after oxathiapiprolin and coumoxystrobin are compounded, and the fungicidal composition can be used for preventing and controlling fungal diseases such as late blight, downy mildew, leaf mold, powdery mildew, anthracnose, rust disease, banded sclerotial blight and early blight on vegetables, fruit trees and flowers.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing fluthiapiprofen and its application for preventing and treating diseases on crops, and belongs to the technical field of pesticides. Background technique [0002] In production, chemical pesticides are mainly used to control downy mildew, late blight, powdery mildew, anthracnose and leaf mold. Hydroxypyrimidine, phenoxyquinoline, triazole and methoxyacrylate fungicides. Due to the long-term use of these agents, drug resistance has been produced to varying degrees, and the control effect has been reduced. In addition, triazole agents can inhibit the growth of crops when used in large doses, and easily cause phytotoxicity. Therefore, it is urgent to research and develop new effective control agents. [0003] Fluthiapiprolin, English common name: oxathiapiprolin, is the first piperidinyl thiazole isoxazoline fungicide newly developed by DuPont. ...
