摘　　要：进行了阿米西达控制杧果采后病害的研究.结果表明:在测试的3种药剂中,阿米西达对杧果炭疽病病菌(Colletotrichum gloeosporioides)的菌丝体生长、产孢及孢子萌发均有明显的抑制作用,而对杧果蒂腐病菌(Botrydiplodia the obromae)菌丝体生长的抑制效果较施保功差;采后用100～200μg/mL的阿米西达控制杧果贮运期间炭疽病的发生具有较好的效果,而在此质量浓度时,对杧果蒂腐病和酸腐病的防效则不稳定;阿米西达结合热处理防治杧果炭疽病的效果更好.Azoxystrobin (Amistar), Sporgon and Carbendazol were applied to inhibit the mycelium growth, spore production and spore germination of Colletotrichum gloeosporioides and Botrydiplodia theobromae in vitro, and to control postharvest mango diseases in vivo. The results showed that Azoxystrobin was the best to inhibit mycelium growth, spore production and spore germination of Colletotrichum gloeosporioides among them. But Sporgon was better to inhibit mycelium growth of B. theobromae than Azoxystrobin. Fruit dipping in Azoxystrobin (100~200 mgmL) could control anthracnose of postharvest mango, but it is difficult to control stem-end rot and sour rot of mango fruits at this concentration. Azoxystrobin followed by hot water treatment controlled mango anthracnose better than Azoxystrobin alone.
