Abstract

Polygonatum odoratum (Mill.) Druce has been widely used in traditional Chinese medicines owing to its renown antioxidant, anticancer, and antidiabetic properties. During surveys conducted in the Zhijin County, Bijie City, Guizhou Province in China, prominent yellow-brown spots were observed on the leaves of P. odoratum. These spots eventually led to the death of the entire plant as they expanded, thus affecting the yield and quality of P. odoratum. In this study, infected P. odoratum leaves were collected and, based on morphological characteristics and multi-locus sequence typing (MLST) (actin, glyceraldehyde-3-phosphate dehydrogenase, beta-tubulin, and the internal transcribed spacer region of rDNA), Colletotrichum camalliae Massee was isolated and identified as the causal agent of the disease. This is the first study to investigate P. odoratum leaf infection by C. camelliae and is therefore, of great significance for this popular and highly valued medicinal plant; furthermore, it provides a sound theoretical basis for targeted control of the leaf spot disease.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
