INFORMATION ABOUT THE VIRUS

Vector:  Aphids, including Green Peach aphid, Myzus persicae, and other aphid species.
Main host plants:  Onion, garlic leek and shallot.Virus Particle:  Filamentous particles containing RNA genome
Virus Infection:  Onion Yellow Dwarf Virus (OYDV) infects onion (Allium cepa), shallot (Allium cepa var. ascalonicum), garlic (Allium sativum), and leek (Allium porrum), and causes yield losses in these Allium crops.  Common symptoms of infected onion include leaf striping and plant stunting.  OYDV induces leaf mosaic in garlic and is part of the garlic mosaic virus complex.
