Abstract The physiological races of tomato leaf mold collected from the eastern three provinces were analyzed by using differential host.Among the collected 33 pathogen strains, the main physiological races were 1.2.3, 1.2, 2.3, 1.2.3.4 and 1.2.4, and 1.2.3.4 was the dominant race,1.2.3.4 and 1.2.4 were new races.New resistant genes should be introduced into tomato breeding.
