Screening of fungal antagonists against yellows of cabbage caused by Fusarium oxysporum f. sp. conglutinans was carried out. We obtained 78 seed-borne fungal isolates from 20 kinds of vegetable roots. Fifty-five soilborne fungal isolates were obtained from the surface-sterilized roots of seven vegetables. Twelve isolates were from field soil using a baiting method. By in vitro and in vivo screening, two seedborne species of Penicillium (S-34) and P. citrinum (S-59), and four soilborne Epicoccum nigrum (TC-33), Fusarium solani (SS-6, CM02), and F. oxysporum f. sp. lactucae (F-9501) suppressed yellows of cabbage effectively. Reductions in disease incidence ranged from 28% to 63%.
