| 摘 要： | 1998～2000年对兰州地区葡萄褐斑病进行了系统观测和调查，结果表明该病害最初于6月中旬开始发病，7～8月为发病盛期，发病率为8%～36%，病情指数为3.0%～17.8%。对采集的病害标样经分离培养，致病性测定和形态特征观察，证明目前兰州地区的葡萄褐斑病是由葡萄拟尾孢菌（Pseudocercospora vitis（Lev.）Speg.）为害所致。

| Abstract: | In recent years,grape brown spot happens in different districts in Lanzhou, and
affects the yield of grape. The disease in Lanzhou was studied from 1998 to 2000. The results
show that it starts to happen from the middle ten days of June,happening most seriously from July
to August. The disease percentage is 8%～36%,and the disease index 3%～17.8%. Based on the
specimens collected in different districts in Lanzhou and the cultural, pathogenicity, morphological
characteristics of the pathogen, it is considered that the pathogen should be Pseudocercospora
vitis (Lev.) Speg. |
