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

[0043] Example 1: 15% bixafen·thianil wettable powder (1:2)

[0044] Mix 5g of bixafen, 10g of thiazilamide, 2g of cleaning agent LS (sodium p-methoxy fatty acid aminobenzenesulfonate), 4g of diffusing agent NNO (sodium methylene bis-naphthalenesulfonate), white carbon Black 5g, kaolin was added to 100g of the mixture and jet milled to prepare a wettable powder with an active ingredient mass percentage of 15% bixafen·thianil.

Embodiment 2

[0045] Example 2: 15% bixafen·thianil wettable powder (1:4)

[0046] Add 3 g of bixafen, 12 g of thiazinil, 3 g of sodium lauryl sulfate, 4 g of diffusing agent NNO, 5 g of white carbon black, and kaolin to 100 g of the mixture and carry out jet milling to obtain 15% mass percent of active ingredients Bixafen·Tianil wettable powder.

Embodiment 3

[0047] Example 3: 14% bixafen·thianil wettable powder (1:6)

[0048] Add 2 g of bixafen, 12 g of thiazinil, 3 g of sodium lauryl sulfate, 4 g of diffusing agent NNO, 5 g of white carbon black, and kaolin to 100 g of the mixture and carry out air-jet milling to obtain an active ingredient mass percentage of 14%. Bixafen·Tianil wettable powder.

Abstract

The invention discloses a bactericidal composition containing bixafen and thiazil and an application thereof. The bactericidal composition uses bixafen and thiazil as main active ingredients, wherein the mass ratio of bixafen to thiazil is 1-70:1-50. The bactericidal composition can be applied to the prevention and treatment of cereals, fruit trees, and vegetable diseases, has a high synergistic effect, overcomes and delays the drug resistance of pathogens, has fast sterilization speed, long-lasting effect, reduces application costs, and has good control effect. Significantly better than its single dose use. The invention can be used to prevent and control fungi on crops, especially to prevent and control fungal diseases such as leaf spot, leaf rust, downy mildew, rice blast and blight, and the effect is better than that of a single dose.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with bixafen and thiazil 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] Tiadinil, molecular formula: C 11 h 10 ClN 3 OS, chemical name: 3'-chloro-4,4'-dimethyl-1,2,3-thiadiazole-5-carboxanilide. Structural formula: [0006] [0007] Thiadinil is a novel systemic fungicide, which can be rapidly transmitted to other parts through root absorption. The drug itself has poor inhibitory activity against pathogens, and can induce the production of disease-resi...
