To effectively prevent and control the diseases and pests in Cynanchum atratum Bge., and improve crop yield and quality, the common species and characteristics of diseases and pests in this plant were analyzed, and its comprehensive prevention and control measures were elaborated. In practice, common diseases of this plant included root rot and leaf spot disease. Root rot disease could occur throughout the entire growing season, and the root system was its main affected area. The pathogenic bacteria were various Fusarium spp. Soil moisture, soil fertility, environmental temperature, planting density, and crop continuous cropping were the main influencing factors for its occurrence; leaf spot disease could easily hinder plant growth, weaken photosynthesis, and was caused by Alternaria spp. Seasonal changes, planting density, soil fertility, and variety resistance were the main influencing factors for its occurrence. Common insect pests included aphids and grubs, among which aphids affected the normal morphology and growth of plants, reduced seed setting rate and quality, and exhibit obvious seasonal changes. They form peaked period before the arrival of high temperatures in summer and when temperatures gradually decrease in autumn, with temperature, humidity, and light being the main influencing factors; grubs feed on the root system of the plant, affecting the absorption and transportation of water and nutrients by the Cynanchum atratum Bge. This pest completed one generation reproduction in most areas within 1-2 years, and soil properties and climatic conditions were the main influencing factors for its occurrence. In terms of prevention and control measures, physical methods such as manual hunting and trapping with tools could effectively control the spread of diseases and pests; selection and application of appropriate fungicides, pesticides and other chemical control means, such as root rot treatment by irrigation and aphid control by spray, could reduce its adverse effects; used beneficial microorganisms and introduced natural enemies insects for biological control could enhance plant disease resistance; adopted reasonable crop rotation and intercropping, strengthening field management and other agricultural control methods could reduce the risk of disease and pest occurrence. This article provides references for improving the level of disease and pest control in Cynanchum atratum Bge. and promoting the sustainable development of the industry.
