Abstract

The invention relates to a bactericidal composition with fenpyrazamine.The bactericidal composition comprises effective components including an active component A and an active component B.The active component A is selectively the fenpyrazamine, the active component B is selectively an optional one of chemical compounds including boscalid, fluxapyroxad, PEIP, fluopicolide and fluazinam, and a weight ratio of the active component A to the active component B is 1:80-60:1.The bactericidal composition has the advantages that the bactericidal composition is high in activity for diversified diseases of crops, obvious synergistic effects can be realized, and the bactericidal spectrum can be expanded; the bactericidal composition is low in dosage and obvious in efficiency and can resist rain drop erosion.

Description

[0001] This application is a divisional application. The original application is a patent application of Shaanxi Thompson Biotechnology Co., Ltd. "A Fungicidal Composition Containing Amazepam". The application number of the original application is: 2012105594740, and the original application date is 2012.12.20 . technical field [0002] The invention belongs to the technical field of pesticides, and relates to the application of a fenfluram-containing bactericidal composition on crop diseases. technical background [0003] Fenpyrazamine is a pyridine-based heterocyclic fungicide. A 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 to control botrytis and is used for grapes, cucumbers, citrus, potatoes, peppers, eggplants, and ornamental plants. [0004] Boscalid, flufenapyramide, boscalid, flubocalid or fluazinam are all widely used in ...
