Plants were inoculated by spraying conidial sus- pensions on the surface at the 4-leaf stage and the heavy spore suspensions were about 10 spores mL After inoculated, the plants were maintained at 100% relative humidity (RH) and from 22 to 25 C in propagators for 3 days after which the humidity was lowered to about 80% RH for 11 days.
