Abstract
Four viruses were detected in severely diseased plants of white Italian garlic from a property in central Victoria. The symptoms included curling, chlorosis, streaking and mosaic of the leaves and stunting of the whole plants. The rhabdovirus, lettuce necrotic yellows virus (LNYV), was one of the viruses isolated from the infected garlic but it was not clear if any specific symptoms could be attributed to it. This is the first record of LNYV infecting a monocotyledon. A probable carlavirus, similar in morphology to garlic latent virus (GLV), was observed under the electron microscope, but produced no symptoms in indicator plants. The potyvirus, garlic yellow streak virus (GYSV), was identified, and was accompanied by at least one other unidentified potyvirus, as undecorated, potyvirus-like particles were observed under the electron microscope alongside those decorated by GYSV antiserum.
