Abstract

The invention relates to a bactericidal composition containing cyprodinil and fluoxastrobin and application thereof. The bactericidal composition contains cyprodinil and fluoxastrobin, wherein the weight ratio of cyprodinil to fluoxastrobin is (1-40):(1-40). The bactericidal composition disclosed by the invention can be applied to the prevention and control of commercial crop diseases and has the advantages of wide application range, good effect, low cost, low residue and safety for human, livestock, environment and the like.

Description

technical field [0001] The invention relates to a fungicidal composition and its use, in particular to a fungicidal composition containing cyprodinil and fluoxastrobin and its use, which is mainly used for the prevention and treatment of economic crop diseases. Background technique [0002] Cyprodinil (Cyprodinil, CAS No. 121552-61-2) is a methionine biosynthesis inhibitor that has no cross-resistance with triazoles, imidazoles, morpholines, phenylpyrroles, etc. , leaf penetration and root systemic activity. Foliar spray or seed treatment can also be used as barley seed coating agent. [0003] Fluoxastrobin (Fluoxastrobin, CAS No. 193740-76-0) is a methoxyacrylate fungicide, and its mechanism of action is to inhibit mitochondrial respiration, that is, through cytochrome b and C 1 Inter-electron transfer inhibits mitochondrial respiration. There are many fungicides that act on mitochondrial respiration, but the site of action of methoxyacrylate compounds (cytochrome b) is ...
