为 z-15在植物病害防治上的应用提供参考，采用平板对峙法、发酵液抑菌法和抑制孢子萌发法测定嗜铁真菌 z-15对4种病原菌的影响。结果表明，z-15对4种病原菌均有不同程度的抑制作用，平板拮抗试验中，除西瓜枯萎病菌以外，对另3种病原菌的抑制率均超过20％，其发酵液对小麦根腐病菌（Bipo-laris sorokiniana ）的生长抑制效果较为显著，最高抑制率达50．9％；对西瓜枯萎病菌和水稻恶苗病菌孢子萌发亦有较好的抑制作用。
為 z-15在植物病害防治上的應用提供參攷，採用平闆對峙法、髮酵液抑菌法和抑製孢子萌髮法測定嗜鐵真菌 z-15對4種病原菌的影響。結果錶明，z-15對4種病原菌均有不同程度的抑製作用，平闆拮抗試驗中，除西瓜枯萎病菌以外，對另3種病原菌的抑製率均超過20％，其髮酵液對小麥根腐病菌（Bipo-laris sorokiniana ）的生長抑製效果較為顯著，最高抑製率達50．9％；對西瓜枯萎病菌和水稻噁苗病菌孢子萌髮亦有較好的抑製作用。

The inhibition effect of Talaromyces flavu Z-15 (siderophilic fungi)against Colletotrichum gloeosporioides,Fusarium.oxysporum,Fusarium moniliforme and Bipolaris sorokiniana was determined by Petri dish method,fermented liquid antibacterial method and inhibiting spore germination method.The results showed that Talaromyces flavu Z-15 has the inhibition effect against four pathogenic fungi to varying degrees.The inhibition rate against Colletotrichum gloeosporioides ,Fusarium moniliforme and Bipolaris sorokiniana is over 20% in Petri dish test.The inhibition rate of the fermentation liquor against growth of Bipolaris sorokiniana can reach 50.9%,and the inhibition rate of the fermentation liquor against spore germination of Fusarium. oxysporum, Fusarium moniliforme and Colletotrichum gloeosporioides is 100%,98.3% and 81.2% separately.
