Problems solved by technology

[0008] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge

Embodiment 1

[0044] Example 1: 15% bixafen-syringstrobin wettable powder (1:2)

[0045] Bixafen 5g, syringstrobin 10g, detergent LS (sodium p-methoxy fatty acid aminobenzene sulfonate) 2g, diffusing agent NNO (sodium methylene bis-naphthalene sulfonate) 4g, white carbon black 5 g of kaolin was added to 100 g of the mixture for jet milling to prepare a wettable powder with an active ingredient mass percent of 15% bixafen-syringstrobin.

Embodiment 2

[0046] Example 2: 15% bixafen·syringstrobin wettable powder (1:4)

[0047] Add 3g of bixafen, 12g of syringstrobin, 3g of sodium lauryl sulfate, 4g of diffusant NNO, 5g of white carbon black, and kaolin to 100g of the mixture and carry out jet milling to obtain 15% biphenyl by mass percent as the active ingredient Bispyramid·syringstrobin wettable powder.

Embodiment 3

[0048] Example 3: 14% bixafen·syringstrobin wettable powder (1:6)

[0049] Add 2 g of bixafen, 12 g of syringstrobin, 3 g of sodium lauryl sulfate, 4 g of diffusant NNO, 5 g of white carbon black, and kaolin to 100 g of the mixture and carry out jet milling to obtain a mass percentage of 14% biphenyl Bispyramid·syringstrobin wettable powder.

Abstract

The invention discloses a bactericidal composition containing bixafen and coumoxystrobin and an application thereof. The bactericidal composition takes the bixafen and the coumoxystrobin as main effective ingredients, wherein the mass ratio of the bixafen to the coumoxystrobin is (1-70):(1-50). The bactericidal composition can be applied in preventing and curing cereal, fruit tree and vegetable diseases, particularly can be used for preventing and curing powdery mildew, rust disease, damping off, downy mildew, late blight, venturia inaequalis, anthracnose, leaf mold and other fungal diseases, has a relatively high synergistic effect, overcomes and delays the drug resistance of pathogenic bacteria, and is high in bactericidal speed and long in lasting period; the application cost is reduced, and the preventing and curing effects are obviously superior to those of a single agent.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with bixafen and syringstrobin as main active ingredients and its application. Background technique [0002] Bixafen (Bixafen), chemical formula: C 18 h 12 C l2 f 3 N 3 O, chemical name: N-(3′,4′-dichloro-5-fluorodiphenyl-2-yl)-3-(difluoromethyl)-1-methylpyrazole-4-carboxamide. Structural formula: [0003] [0004] Bixafen is a pyrazole fungicide, a new type of systemic fungicide with broad-spectrum, protective and therapeutic activities. [0005] Coumoxystrobin, molecular formula: C 26 h 28 o 6 , chemical name: (E)-2-(2-(3-n-butyl-4-methyl-coumarin-7-yloxy)methylphenyl)-3-methoxymethyl acrylate. Structural formula: [0006] [0007] Syringostycin is a high-end fungicide developed by Shenyang Research Institute of Chemical Industry and Jilin Province Bada Pesticide Co., Ltd. It belongs to the category of methoxyacrylates...
