Abstract: in this paper, SPFMV, SPLV, SPFMMV, SPCSV and SPVMV etc. more than 10 kinds of viruses are briefly summed up. The principles and features of main detection techniques such as biology, serology, and molecular biology are introduced in detail. Biology technique is based on appearance symptom on sweet potato or Ipomoea Setosa after they are infected to identify virus. But it need long period and is apt to be limited by season. Based on coat protein(CP) of virus, serology detects virus during peculiar immunology reaction of antibody and antigen. But it can’t detect virus without CP and preparing antibody need more time. The molecular biology method is based on nucleic acid to detect virus. This technique has high sensitivity, strong veracity, wide suitability etc.
