The PACE threat temperature for Southern blight (Sclerotium rolfsii) is 70F (21C), which means that damage from this disease should start appearing at this temperature. A threat temperature of 70 was reached in LA on 6/16/07, and a Los Angeles superintendent first noticed disease symptoms two days later, on 6/18/07, providing good confirmation that the threat temperature of 70 is accurate.
