Abstract:: Taking Colletotrichum gloeosporioides (Penz.) Sacc.as test fungi，using the mycelium growth rate method and the determination of spore production，the biological characteristics of Colletotrichum gloeosporioides (Penz.) Sacc.were studied and the toxicity of 8 fungicides were tested.The results showed that the suitable media for mycelial growth and spore production were PSA and dextrose peptone agar medium，respectively.The suitable temperature for the mycelial growth was 5-35 ℃ and the best was 25 ℃.The optimum pH was 3 for the spore production.The thermal death temperature of the mycelia was 56 ℃.Colony growth and spore production could adapt to the different illumination conditions.The most favorable carbon source and nitrogen source for mycelia growth were maltose and peptone，respectively.The most favorable carbon source and nitrogen source for spore production were fructose and beef extract，respectively.The toxicity tests showed that prochloraz-manganese chloride complex，carbendazim，fluazinam and pyraclostrobin had higher toxicity on C.gloeosporioides.
