| 摘 要： | 糖槭叶枯病 Phyllosticta negundinis病菌孢子放散开始期和高峰期与每年的温、湿度变化有关。病害发生严重程度与降雨量关系密切 ,降雨早且量大时病害严重。病菌以分生孢子器和分生孢子在病叶上越冬 ,通过气流传播成为翌年初侵染源。喷洒 70 %甲基托布津可湿性粉剂 10 0 0倍液和 75%百菌清可湿性粉剂 80 0倍液均能收到较好的效果

| Abstract: | The spread of the spores of Phyllosticta negundinis is related with temperature and humidity. The infection is closely related to the precipitation.The heavier the rainfall,the more serious the disease.The fungus overwinters as spores and pycnidia on defoliation,which might be the primary source of infection the next year.Spraying 70% Thiophanate methyl wp(1000 times) or 75% Chlorothalonil wp (800 times) could control the disease effectively. |
