芦笋茎枯病(Phoma asparagi Sacc)每年都有不同程度的发生为害,据1983～1986年的调查,一般年份的发病株率为70～90%,个别年份重病田发病株率高达100%,致使植株早期变黄落叶枯死,甚至全田毁灭,已成为我省发展芦笋生产的一大障碍。目前,国内外多从化学药剂方面进行防治,但防治效果不够理想。笔者从1983年开始对本病的病原菌生态及防治方法等进行了试验研究,现将试验研究结果整理如下。

Phoma asparagi Sacc takes place to some extent every year. According to the survey from 1983 to 1986, the incidence rate of common disease in Phoma asparagi Sacc is 70-90%. In some years, the incidence rate of disease in severe disease is as high as 100% Early yellowing of plants dead leaves, and even the whole field destruction, has become a major obstacle to the development of asparagus production in our province. At present, many domestic and foreign prevention and treatment of chemical agents, but the control effect is not ideal. The author started from 1983 on the pathogen ecology and prevention and treatment methods such as experimental study, the test results are summarized below.
