甘蓝尖孢镰刀菌黄化拮抗菌的筛选。进行了粘连试验。从20种蔬菜根部分离到78株种传真菌。从7种蔬菜表面灭菌的根部分离到55株土传真菌。用诱饵法从田间土壤中分离到12个菌株。通过体内外筛选，获得了青霉菌(S-34)和桔青霉(S-59)两个实生种和4个土传黑斑病菌(TC-33)、茄病镰刀菌(SS-6、CM02)和尖孢镰刀菌(F.乳糖(F-9501)能有效抑制甘蓝黄化。发病率降低了28%至63%。
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%.
