摘要
黄山松疱锈病病原菌为Ｃｒｏｎａｔｉｕｍｆｌａｃｃｉｄｕｍ（Ａｌｂ．ｅｔｓｃｈｗ．）ｗｉｎｔ．转主寄主分别为腺毛阴行草、阴行草和松蒿。在皖西大别山区，４月中旬于罹病枝上出现锈孢子器，锈孢子传播期为５５天，５月下旬至６月初为飞散高峰期。锈孢子和夏孢子分别在２０℃、２５℃，饱和相对湿度下萌发最好。夏孢子６月中旬开始传播，６月下旬进入盛期，７月初即可形成冬孢子，冬孢子在饱和的湿度下，４小时可萌发。修枝、伐除病株并结合林地抚育是防治黄山松疱锈病的根本措施。
ccidum(Alb.et Schw.
)Wint.Its alternate hosts are Siphonestegia laeta S. Moore,S. chinensis Benth.,and
Patheirnosmum japonicum (Thunb.) Kanitz. The spreading period of aeciospore in woods
isabout 55 days. The germination ratc of aeciospore and urediospore are 60%and
50%,respectively,under saturated moisture 1%agar water membrane with 25℃,36h.The
teliospore germinates after 4 hours with 25℃ under saturated moisture , and preduces
basidiospores.Smearing saturated Nacl solution on leaves can kill alternate hosts. The
solution of CuSO4(40times)kills aeciospores well.Pruning the infected branches and cutting the
epidemic trees areeffcetive measures to prevent and control the blister rust.
