Abstract
Virus diseases are probably responsible for the mosaic and necrotic symptoms in orchids that are often blamed on other disorders. This circular discusses the four viruses of orchids that have been identified thus far: cymbidium mosaic, orchid tobacco mosaic, vanda mosaic, and cymbidium ringspot. Symptoms in several orchid genera are described, and methods are suggested for disease control. It also tells how to test for these orchid virus diseases on non-orchidaceous, herbaceous plants.
