Research progress on non-fungal diseases of Vicia sativa

Common vetch (Vicia sativa) is an important legume forage and green manure crop in China's grassland agricultural system. In this article, the advances in research on the distribution and damage, pathogens, disease cycles, and control strategies of V. sativa non-fungal diseases are summarized. By the end of the year 2017, there were 38 non-fungal diseases reported for this legume forage worldwide: 4 bacterial diseases, 5 viral diseases, 24 nematode diseases, and 5 parasitic seed plant diseases. These diseases occurred in 15 countries, including China, the United States, the United Kingdom, Australia, and Morocco. Diseases caused by Pratylenchus coffeae and Meloidogyne hapla only occurred in China. To date, evaluation of loss, life cycle, and management of diseases, such as chocolate spot, leaf roll, and those caused by mosaic virus and nematodes Meloidogyne incognita, Meloidogyne hapla, Meloidogyne arenaria, and Pratylenchus penetrans, has been performed at various levels; however, there have been few studies on other diseases. In the future, we should strengthen the research on diseases caused by other pathogens, and increase the integration of studies on diseases of V. sativa and other crops.
