A preliminary investigation of diseases and insect pests was carried out in several representative planting regions of Astragalus membranaceus (Fisch) Bge. var mongolicus (Bge.) Hsiao by the spatial and temporal distribution method. The results showed that powdery mildew and root rot diseases are the most serve among the six types of diseases found in A. membranaceus var mongolicus, and meloidae, lima bean pod borer and plant louse are the most harmful among the twenty-three types of insect pests found in this species. Clarification of plant diseases and insect pests in A. membranaceus var mongolicus as well as their damaging extent may provide a reference for the control study regarding the diseases and insect pests in A. membranaceus var mongolicus.
