对南京地区竹叶锈病的病原及发生规律进行了研究。结果表明：南京地区竹叶锈病的病原主要有3种，分别为刚竹柄锈菌(Puccinia phyllostachydis)、长角柄锈菌(Puccinia longicornis)和竹夏孢锈菌(Uredo ignava)。刚竹柄锈菌和长角柄锈菌主要以冬孢子堆在竹叶越冬，二者的初侵染源主要是冬孢子堆下面的菌丝产生的夏孢子，此外，刚竹柄锈菌的初侵染源还包括少量能越冬的夏孢子堆。竹叶锈病的潜育期为10~15 d，夏孢子可造成多次侵染，6月及10月为侵染高峰期。竹叶锈病的发生未发现转主寄生现象。

The pathogens and their occurrence rhythm of bamboo leaf rust in Nanjing were studied. The bamboo leaf rust mainly has three types of the pathogens, namely Puccinia phyllostachydis, Puccinia longicornis and Uredo ignava. The overwintering of P.phyllostachydis and P.longicornis were mainly as the mode of teleutosorus on bamboo leaf. The primary infection source of the pathogens is the urediospore produced by the mycelium under the teleutosorus, and the primary infection of P.phyllostachydis also includes the few uredinium that can live through the winter. The bamboo leaf rust has an incubation period of 10—15 days. After several infections by urediospores, the conditions of the disease reach peaks from June to October. During the process, heteroecism never occurs.
