Lily southern blight was caused by Sclerotium rolfsii Sacc. When 5 dried sclerotis (Inoculum density about 2.6 sclerotia per 100cm3 of soil) were inoculated into soil around the bulb of lily within 1cm, the yellowing symptom could appear obviously within 2 weeks. Moreover, the disease severity increased gradually with the increasing number of inoculating slcerotia. Eight varieties of lily tested for resistance to S.rolfsii (Sr029) indicated that all of them could be infested in 2 weeksafter inoculation. Varieties polyana and Cote d'azur or lilium asiatichybrid group were more susceptible than others. All of the growth stages of lily were susceptible to the pathogen especially at the visible bud stage. On soil plate, the maximum sclerotial germination occurredat 20-28oC. The percentage of germination was increased when the sclerotia were incubated under drying condition for 3 days at 20oC and thenremoistened and placed at 28oC. Consistently, the greater disease severity was obtained when the lily plants were transferred into the 28oC condition after 1 week of incubation under 20oC. In general, the best solute water potential for sclerotial germination and mycelial growth was between -1 and -10 bars. However, with decreasing of solute water potential from -10 to -50 bars, the percentage of germination and growth rate were decreased. Changing soil moisture promoted disease severity: the disease severity was about 0.75 when soil moisture was adjusted to about 30% moisture holding capacity (MHC) and then progressively.
