Using the agar medium inoculation method, three isolates of Phytophthora sojae were tested for virulence on six cultivars. In about 10 days, they were classified into race A, B or H, respectively. That period was from 14 to 19 days earlier than the conventional flooding inoculation method. Our proposed new method is available for the pathogenic test of Phytophthora sojae.
