1、盆栽红掌有时会出现花早衰、畸形、粘连、裂隙及玻璃化和蓝斑等现象，这多为施肥、盆土和空气湿度管理不当或品种原因引起的生理性病害。

2、炭疽病。炭疽病是红掌常见病害之一。病原是盘长孢属或刺盘孢属真菌。前者症状是沿叶脉形成圆形棕色病斑，之后病斑连在一起，形成具有棕黄色边缘的大病斑，病部最后干枯。后者与前者相似，在分生孢子盘上长有黑色坏毛，且会引起花腐，在肉穗花序上形成黑色坏死斑点。高湿是发生该病的主要原因。

防治方法：对细菌性疾病没有特效药，主要的防治方法是加强栽培管理，以预防为主。预防又可通过环境预防和肥料预防实现。环境预防主要是加强温室的温度（细菌理想的繁殖条件是30度左右）的控制、卫生环境和生产区人员、作业工具的流动等。肥料预防要在植株生长中尽量不用高NH4态的氮肥。同时要去处或隔离病株。
