The comparative biological activity of 21 naturally occurring or synthetically derived steroids, 7 tetracyclic and pentacylic triterpenoids, and antheridiol incubated with cultures of Phytophthora cactorum has been examined. There was greater dependence on precise steric features of the sterol side chain than on the extent of nuclear unsaturation in inducing oospore formation. There was no sign...

The soil pathogenic fungus Phytophthora cactorum causes the most dangerous diseases occurring in strawberry plantations—strawberry crown rot and leather rot. Modern biotechnology methods, e.g., vitro culture selection molecular diagnostics can be utilized of cultivars that are less susceptible or resistant to diseases. In this study, four microclones: ‘Elsanta’, ‘Feltar’, ‘Teresa’ ‘Plena SVdT’ ...
