摘要

Our knowledge on molecular basis of life cycle development of oomycete phytopathogens has been compiled in last two decades, which is indicating that the inter-relationships between host plant and phytopathogen are elaborately regulated by chemical signaling substances. In contrast, chemical weapons in nonhost plants which can affect/interfere the life cycle development of oomycete phytopathogens, are supposed to be responsible for their incompatibility to Oomycetes. These facts suggest us some cues for biorational regulation of soilborne oosporogenic and zoosporogenic pathogens which are often difficult to eradicate. The research trend of oomycete pathogens based on ecological chemistry has been briefly reviewed with special reference to Aphanomyces cochlioides.
