According to the mode of action​​​​​​​

1. The systemic fungicide can be absorbed by plant leaves, stems, roots, and seeds into the plant body, and can be transported, diffused, retained or produced metabolites through plant body fluids, which can prevent some diseases that penetrate into the plant body or the endosperm of seeds. It protects crops from infection by pathogens or treats infected plants, so it has therapeutic and protective effects. Such as carbendazim, niclostrobin, kresoxim-methyl, domycin, samoyphos, hymexazol, metalaxyl, fosphoaluminum, thiophanate methyl, dixon, fenpirin, copper toluene, antitoxin, Seed dressing and so on.

2. Non-systemic fungicide means that the medicament cannot be absorbed, transmitted and retained by the plant. At present, most varieties are non-systemic fungicides. Such agents are not easy to make pathogens resistant and are relatively economical. However, most of them only have protective effects and cannot prevent and control diseases that penetrate deep into the plant. Such as propamocarb, copper sulfate, docarbutin, chlorothalonil, green milk copper, surfactant, synergist, sulfur mixture, plant ash, Bordeaux mixture, mancozeb, thiram, chlorothalonil, etc. In addition, fungicides can also be classified according to the method of use, such as seed treatment agents, soil disinfectants, sprays, etc.
