| Abstract: | Ten species of Pythium recently isolated from solis and infected plants in Ningxia were reported, and the emergence frequency of Pythium in each area of Ningxia were estimated and analysed. P. ultimum proved to be a dominant species in farmland of Ningxia. Seven of the 10 said species were examined for their pathogenicity to 13 vegetables. Pathogenic difference of P. ultiumum and P. aphaniderrnatum were studied. |
