| 摘 要： | 杜松赤枯病是 4年生以上杜松幼树的主要病害 ,在我省为害严重。研究表明 ,此病是由Alternariasp .和Phomasp .共同侵染所致。Alternariasp .以菌丝体和分生孢子越冬 ,Phomasp .以菌丝体和分生孢子器越冬。两种病原菌均通过皮孔、气孔和伤口侵入树体。两种病原菌的孢子均在5月下旬日平均气温达 16℃左右时开始放散 ,孢子的放散和萌发与空气温度的关系最为密切 ,雨季是孢子放散的高峰期。通过对 12种杀菌剂的室内药效测定 ,以及四种杀菌剂的室外防治试验 ,得出用 4 0 0～ 80 0倍液的多菌灵等连续防治 2～ 3年 ,可完全控制该病的发生和蔓延 ,防治方法简便易行 ,成本低廉 ,功省效宏 |

| Abstract: | Copper blight is one of the major diseases of Juniperus regida.Study showed that the disease is infected by Acternaria sp.and Phoma sp.The former overwinters in mycelia and conidium;the latter overwinters in mycelium and pycnidium.The two mobifical agents infect into trees by lenticel,stomate and wound,The spores begin spread during about 16 ℃ of average temperature in the last ten days of May.Rainy season is the peak time for spore spreading.Experiment indicated,that occurrence and spreading of this disease can be controlled completely using 400～500 times of Bavistin solution to control for 2～3 years. |
| Keywords: | copper blight of Juniperus regide occurrence regulation control |
