为了解湖南省保护地草莓灰霉病的发生与防治情况,2013年2~4月对位于湖南省湘南的郴州、衡阳,湘东的长沙、株洲、湘潭,湘中的邵阳,湘北的岳阳、湘西的怀化等地区的保护地灰霉病的发生和防治情况进行了调查。结果表明：1各调查地区草莓灰霉病普遍发生,但发生严重程度存在差别,其中湘中邵阳市大兴村的病果率和病情指数最高达到46.67%和6.34,湘南衡阳师古村病果率次之,但并不严重,其他地区病果率和病情指数均呈正相关;2连作棚年限越长,病害发生越严重;轮作棚草莓灰霉病的发生相对较轻,病果率介于9%~14%之间,而且病害发生也不严重;3不同草莓品种抗病能力不同,中章姬品种的草莓病果率和病情指数较低,其次为法兰地、红颜品种的草莓和丰香品种的草莓病果率和病情指数相当,甜查理的病果率和病情指数最高,发病最严重;4定植时期早晚对草莓灰霉病的发生有影响,其中9月上中旬定植草莓灰霉病病果率和病情指数均较高;9月下旬至10月上旬定植病害的发生相对较轻;10月中旬及其以后定植不仅抗寒效果差,而且产果慢,经济效益差;5不同大棚类型也影响草莓灰霉病发生的轻重,其中全封闭立柱拱棚的病果率和病情指数最高为38%和5.87,简易连栋拱棚次之,拱形单栋式拱棚和无立柱半封闭拱棚相当,日光智能温室大棚发生最轻;6当前,湖南省防治草莓灰霉病使用最多的药剂是腐霉利,多菌灵次之,其他农药依据所占调查比例的高低依次为甲基托布津、嘧菌环胺、咯菌腈、异菌脲、多抗霉素、甲基嘧菌。首次对湖南省保护地草莓灰霉病发生情况的调查,其结果将为进一步开展湖南省保护地草莓灰霉病的系统研究和防控奠定基础。

英文摘要：

In order to understand the occurrence and control of strawberry grey mould in plastic green houses in Hunan Province,the situation of the disease was investigated during February ~ April in 2013 over plastic green houses in cities of east,central,north,and west areas of Hunan Province. The results showed that 1 the disease occurred commonly,however,there were some difference among these areas. Among them in Daxing village of Shaoyang city diseased fruit rate（ DFR） and disease index（ DI） was as high as 46. 67 % and 6. 34 respectively. The DFR in Shigu village of Hengyang city came the second,though not serious. Among other regions,there existed a certain positive correlation between DFR and DI. 2 The longer of continuous cropping the graver the disease occurred. The occurrence of the disease was light in those green houses where rotation cropping was taken,the DFR was between 9% ~14%,and the diseases were not grave. 3 Different variety has different premunition against the disease,Akihime had the lowest index of DFR and disease condition（ DC）,followed by Flange,Hongyan and Fengxiang varieties had equivalent rate and index. While sweet Charles had the highest index of DFR and DC. 4 The time of plant setting also affected the occurrence of the disease; DFR and DC were fairly high when plant setting was in the 1st and 2nd 10 days of September; while those in the last 10 days of September and the 1st 10 days of October were fairly light; those in the 2nd 10 days and / or later,the plant had low cold resistance and sluggish fruiting,therefore,poor economic returns. 5 The type of green house also affects the occurrence intensity of the disease,among them totally enclosed stud arched green house had the highest DFR and DC index,they were 38% and 5. 87,followed by simple,having joint ridgepole,and equivalent with arched single ridgepole,non-stud one; While the sunlight,smart plastic green houses had the lightest rate. 6 The most common used pesticide to control the disease according to the high-and-low proport
