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-epiconazole wettable powder (1:2)

[0044] Mix bixafen 5g, epoxiconazole 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 is added to 100 g of the mixture, and the mixture is jet-milled to obtain a wettable powder with an active ingredient mass percentage of 15% bixafen-epifenazole.

Embodiment 2

[0045] Example 2: 15% bixafen-epiconazole wettable powder (1:4)

[0046] Add 3 g of bixafen, 12 g of epoxenazole, 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 a mixture with a mass percentage of 15% active ingredient. Phenopyram·econazole wettable powder.

Embodiment 3

[0047] Example 3: 14% bixafen-epiconazole wettable powder (1:6)

[0048] Add 2 g of bixafen, 12 g of epoxenazole, 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 a mixture with a mass percentage of 14% active ingredient. Phenopyram·econazole wettable powder.

Abstract

The invention discloses a sterilization composition containing Bixafen and epoxiconazole and application thereof. The sterilization composition takes the Bixafen and the epoxiconazole as main effective ingredients, wherein the mass ratio of the Bixafen to the epoxiconazole is (1-70):(1-50). The sterilization composition can be used for preventing and curing cereal, fruit tree and vegetable diseases, has a higher synergistic interaction action, overcomes and delays the drug resistance of bacteria, has the advantages of high sterilization speed and long lasting period and lowers application cost, and the prevention and cure effect of the sterilization composition is obviously superior to the prevention and cure effect brought when the Bixafen or the epoxiconazole is singly used. The sterilization composition can be used for preventing and curing fungi on crops, and can be especially used for preventing and curing fungal diseases including powdery mildew, rust disease, downy mildew, damping off, Pseudocercosporella herpotrichoides and the like, and the effect of the sterilization composition is obviously superior to the effect brought when the Bixafen or the epoxiconazole is singly used.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with bixafen and epoxiconazole 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] Epoxiconazole (epoxiconazole), molecular formula: C 17 h 13 ClFN 3 O, chemical name: (2RS,3SR)-1-[3-(2-chlorophenyl)-2,3-oxo-2-(4-fluorophenyl)propyl]-1H-1,2, 4-triazole. Structural formula: [0006] [0007] Epoxiconazole is a triazole fungicide, which has a good control effect on a series of cereal crops such as blight, powdery mildew, eye striae and more than ten kinds of ...
