| Abstract: | Eight species of Pythium were isolated from spring cropping maize seedlings in Dongyang and Tiantai County of Zhejiang Province from April to March, 1990. They were identified to be P. acanthophoron, P. aphanidermatum, P. debaryanum, P. graminicola, P. irregulare, P. spinosum, P. tardicrescens and P. ultimum.
In inoculation tests, all eight species isolated from maize roots were pathogenic to their hosts. They caused corn seed rot, root rot or seedling death. P. aphanidermatum was the most virulent pathogen to spring cropping maize. |
