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

Abstract

The invention discloses a bactericidal composition containing fenpyrazamine and spiroxamine, and application of the bactericidal composition. The bactericidal composition takes fenpyrazamine and spiroxamine as the main effective components, wherein the mass ratio of the fenpyrazamine to the spiroxamine is (1-70):(1-50). The bactericidal composition can be applied to prevention and treatment of cereal, fruit and vegetable diseases, particularly to the prevention and treatment of fungal diseases, such as powdery mildew, rust disease, gray mold and stripe disease, has a relatively high synergistic effect, overcomes and delays the insecticide resistance of germs, is high in bactericide effect and long in lasting time, and reduces the application cost, and the control effect of the bactericidal composition is obviously superior to that of single bactericide.

Description

Technical field: [0001] The present invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with fenpyrafen and spirulina as main active ingredients and its application. Background technique [0002] Fenpyrazamine is a heterocyclic fungicide based on pyridine, molecular formula: C 17 h 21 N 3 o 2 S, chemical name: 1-[(2-propenylthio)formyl]-2-isopropyl-4-(2-methylphenyl)-5-amino-1H-pyrazol-3-one. [0003] Pathogen that inhibits the mechanism of action of the ergosterol biosynthetic pathway, showing inhibition of mycelial growth and spore germination and pollen tube growth. It is mainly used for the control of botrytis and is used for cucumbers, grapes, citrus, potatoes, peppers, eggplants, ornamental plants, etc. [0004] Spiroxamine (Spiroxamine), molecular formula: C 18 h 35 NO 2 , chemical name: N-ethyl-N-propyl-8-tert-butyl-1,4-dioxaspiro[4.5]decane-2-methylamine. Structural formula: [0005] [0006] ...
