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% spirulina syringstrobin wettable powder (1:2)

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

Embodiment 2

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

[0047]Add 3 g of spirulina, 12 g of syringstrobin, 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 a 15% mass percentage of the active ingredient spirocyclic Cyclostrobin·syringstrobin wettable powder.

Embodiment 3

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

[0049] Add 2 g of spirulina amine, 12 g of syringstrobin, 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 14% spirulina Cyclostrobin·syringstrobin wettable powder.

Abstract

The invention discloses a bactericidal composition containing spiroxamine and coumoxystrobin and an application of the bactericidal composition. The spiroxamine and the coumoxystrobin are used as main effective constituents of the bactericidal composition, and the mass ratio of the spiroxamine to the coumoxystrobin is 1-90:1-90. The bactericidal composition can be used for preventing and treating diseases of cereals, fruit trees and vegetables, has high synergism, overcomes and delays pesticide resistance of germs, and is high in bactericidal speed and long in lasting period; application cost is reduced; and the preventing and treating effect is obviously higher than that of a single agent. The bactericidal composition can be used for preventing and treating fungal diseases of crops, and can be particularly used for preventing and treating fungal diseases such as powdery mildew, rust diseases, downy mildew, late blight, scab, leaf mold, anthracnose and apple valsa canker, and the effect of the bactericidal composition is greater than that of the single agent.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with spirulina and syringstrobin as main active ingredients and its application. Background technique [0002] Spiroxamine, chemical formula: C18H35NO2, chemical name: N-ethyl-N-propyl-8-tert-butyl-1,4-dioxaspiro[4.5]decane-2-methylamine. Structural formula: [0003] [0004] Spirulina is a substituted amine fungicide and a sterol biosynthesis inhibitor, which mainly inhibits the synthesis of C-14 deoxymethylase of pathogenic bacteria. The control objects are wheat powdery mildew and various rusts, barley moire and stripe disease. Spirulina is a new type of systemic foliar fungicide, which has special effect on powdery mildew. It acts quickly and lasts for a long time, and has both protective and therapeutic effects. [0005] Coumoxystrobin, molecular formula: C 14 h 13 N 3 , Chemical name: N-(4-methyl-6-prop-ynylpyrimidin-2-y...
