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·thianil wettable powder (1:2)

[0045] Put 5g of pyraclostrobin, 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 is added to 100g of the mixture, and the mixture is jet-milled to obtain a wettable powder with an active ingredient mass percentage of 15% pyraclostrobin·thianil.

Embodiment 2

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

[0047]Add 3 g of pyraclostrobin, 12 g of thiazil, 3 g of sodium lauryl sulfate, 4 g of diffusing agent, 5 g of white carbon black, and kaolin to 100 g of the mixture, and perform air-jet milling to obtain 15% pyroxene by mass percentage of the active ingredient. Pyrazastrobin·thiazilamide wettable powder.

Embodiment 3

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

[0049] Add 2 g of pyraclostrobin, 12 g of thiazinil, 3 g of sodium lauryl sulfate, 4 g of diffusing agent, 5 g of white carbon black, and kaolin to 100 g of the mixture and carry out jet milling to obtain an effective ingredient mass percentage of 14% pyrene Pyrazastrobin·thiazilamide wettable powder.

Abstract

The invention discloses a bactericidal composition containing isopyrazam and tiadinil and application of the bactericidal composition. The bactericidal composition takes the isopyrazam and the tiadinil as main effective components, wherein the mass ratio of the isopyrazam to the tiadinil is (1 to 70):(1 to 50). The bactericidal composition can be applied to control on cereal, fruit tree and vegetable diseases, has higher synergetic effect, and is high in sterilizing speed and long in lasting period; the insecticide resistance of germs is overcome and delayed; the application cost is reduced; the control effect of the bactericidal composition is remarkably superior to that of a single agent of the isopyrazam or the tiadinil. The bactericidal composition disclosed by the invention can be used for controlling fungi diseases on crops, and particularly can be used for controlling fungi diseases such as wheat blight, smut disease, rice blast and powdery mildew; the effect of the bactericidal composition is remarkably superior to that of the single agent.
