Fungicidal composition for prevention and treatment of crop diseases and applications of fungicidal composition

The invention discloses a fungicidal composition for prevention and treatment of crop diseases. The fungicidal composition contains two active components, i.e. zincpolyanemine and pyraclostrobin, wherein the weight ratio of the zincpolyanemine to the pyraclostrobin is (10-30): (1-30). The invention also discloses the applications of the fungicidal composition for the prevention and treatment of crop diseases in preventing and treating diseases such as wheat powdery mildew, anthracnose of tomato, grape anthracnose, powdery mildew and rice blast. The fungicidal composition can produce a good synergistic effect and overcome and delay the disease resistance of diseases, the prevention and treatment spectrum is expanded, the drug cost is lowered, and the environment pollution is reduced.
