Abstract

Golden buckwheat (Fagopyrum dibotrys) is a well-known edible herb with significant medicinal and economic values in China and other Asian countries. In May and June of 2022, an outbreak of leaf blight on F. dibotrys was observed in Weixi Lisu Autonomous County, Diqing Tibetan Autonomous Prefecture, Yunnan Province, China. The infected plants exhibit symptoms like leaf necrosis and wilt with frequent leaf curling or distortion. Cladosporium-like strains were consistently isolated from the diseased leaf tissues. Based on morphological characteristics and multi-gene (ITS, tef1, and act) phylogenetic analyses, the fungi were identified as Cladosporium cladosporioides. Pathogenicity tests showed that the selected C. cladosporioides strain could infect F. dibotrys leaves using non-wound inoculation. This represents the first report that C. cladosporioides causes leaf blight on F. dibotrys in China and the world.

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.
