| 中文摘要: |
| 为明确黄芪麻口病的成因，在甘肃陇西县多年种植的黄芪田进行调查、采样和防治试验。通过对黄芪根腐病菌的分离鉴定及根结线虫的分离，明确了根腐病菌不是黄芪麻口病的致病菌，在供试的麻口病株上未分离到线虫。经过回接地下害虫试验，确认黄芪根瘤象（Sitona ophtalmicus Desbrochers）幼虫的取食为害，是造成黄芪麻口病发生的主要诱因，经中科院动物所专家鉴定该虫为中国新记录种。田间药剂防治试验结果显示，黄芪移栽前用5%丁硫克百威颗粒剂 45 kg/hm2土壤处理，用15%阿维·毒乳油30 kg/hm2灌根，防治效果良好，一次灌根的防治效果达87.51%，挽回92.14%的产量损失。 |
| 英文摘要: |
| The causes of Makou disease of Astragalus mongholicus were studied by means of field investigation, sampling and control tests in the continuous A.mongholicus fields in Longxi County. By isolation and identification of foot rot disease and separation of nematodes, it showed that the pathogen of the root rot disease did not cause Makou disease of A.mongholicus; nematodes were not isolated from the diseased plants. After inoculating underground pest, it was determined that feeding by the larvae of Sitona ophtalmicus Desbrochers was the fundamental cause for Makou disease of A.mongholicus, and the species was identified as a new record in China. Control efficacy tests in fields indicated that the control effect was 87.51% and 92.14% of the output could be redeemed by soil treatment with 5% carbosulfan GR (45 kg/hm2) before transplanting and by one time irrigating of roots treated with 15% abamectin and chlorpyrifos EC（30 kg/hm2）. |
