| Abstract: | A number of compounds isolated from various plant species were tested for their ability to affect the mobility of zoospores of the fungus Aphanomyces cochlioides which causes root rot in spinach (Spinacia oleracea). Compounds may act as attractants, repellents or stimulants of zoosphore movement or they may halt movement by causing the spore to clump and settle. Bioassay revealed compounds with these methods of action, as well as some which acted directly on the fungus. ©1999 Society of Chemical Industry |
