Problems solved by technology

[0007] 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% pyraclostrobin·thifuramide wettable powder (1:2)

[0045] Put 5 g of pyraclostrobin, 10 g of thiofluxamide, 2 g of cleaning agent LS (sodium p-methoxy fatty acid aminobenzene sulfonate), 4 g of diffusing agent NNO (sodium methylene bis-naphthalene sulfonate), white carbon black Add 5 g of kaolin to 100 g of the mixture and carry out jet milling to obtain a wettable powder with an active ingredient mass percentage of 15% pyraclostrobin·thifuramide.

Embodiment 2

[0046] Example 2: 15% pyraclostrobin Thiofuramide wettable powder (1:4)

[0047]Add 3 g of pyraclostrobin, 12 g of thifluzamide, 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 for jet milling to obtain 15% by mass of the active ingredient pyrazole Naproxamid Thiofuramide wettable powder.

Embodiment 3

[0048] Example 3: 14% pyraclostrobin Thiofuramide wettable powder (1:6)

[0049] Add 2 g of pyraclostrobin, 12 g of thifluzamide, 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 for jet milling to obtain 14% pyrazole by mass as an active ingredient Naproxamid Thiofuramide wettable powder.

Abstract

The invention discloses a fungicidal composition containing isopyrazam and thifluzamide and an application thereof. According to the fungicidal composition, isopyrazam and thifluzamide serve as main active ingredients, wherein the mass ratio of the isopyrazam to the thifluzamide is (1-70):(1-50).The fungicidal composition can be applied to controlling cereal diseases, fruit tree diseases and vegetable diseases, and has the high synergistic interaction effect, the pesticide resistance of pathogenic bacteria is overcome and delayed, the sterilization speed is high, the lasting period is long, application cost is reduced, and the control effect is obviously better than the use effect of a single-component pesticide. The fungicidal composition can be used for controlling fungi diseases on crops and particularly can be used for controlling fungi diseases such as wheat take-all diseases, wheat powdery mildew and phyricularia oryzae, and the effect is remarkably better than the use effect of the single-component pesticide.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with pyraclostrobin and thifuramide as main active ingredients and its application. Background technique [0002] Isopyrazam, molecular formula: C 20 h 23 f 2 N 3O , Chemical name: 3-difluoromethyl-1-methyl-N-[1,2,3,-tetrahydro=9-(1-methylethyl)-1,4-methanonaphthalen-5-yl] -1H-pyrazole-4-carboxamide. [0003] Pyrafenapyramide is a pyrazole fungicide, a new type of systemic fungicide with spectrum, protective and therapeutic activities. [0004] Thiofuramide (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: [0005] [0006] Thiofuramide 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 productio...
