研究发现制霉素（14．4～16．0mg·L－1）、K制剂（4．0mp·L－1）和孔雀绿（3，0～40mp·L-1）对镰刀菌Fu2和尖F1抑制效果好，而对Fu1-2抑制效果差；优氯净（2．0mg·L－1）能抑制Fu1-2，而不抑制Fu2和尖F1；龙胆紫（1．0mg·L-1）可抑制尖F1，而不抑制Fu2和Fu1-2制霉素对鱼毒性最小，而孔雀绿毒性最大．
The results showed that Fusarium oxysporum fusiformis Fu2 was sensitive to nystatin (14.4 ~ 16.0 mg · L -1), K (4.0mp · L -1) and malachite green (3,0 ~ 40mp · L -1) F1 had a good inhibitory effect on Fu1-2, while Fu1-2 had a poor inhibitory effect. Fumachlor (2.0mg · L-1) inhibited Fu1-2, 1) inhibits spike F1 without inhibiting the toxicity of Fu2 and Fu1-2 to nystatin, while malachite green has the highest toxicity.
