Orchid Pathogen Diagnostics

Our goal is to simplify pathogen detection so you can keep your collection healthy. We offer a suite of molecular and do-it-yourself (DIY) serological test kits and services for the detection of pathogens in orchids.

The two most common orchid viruses, Cymbidium mosaic virus (CymMV) and Odontoglossum ringspot virus (ORSV), are spread by humans, when propagating plants or cutting flowers. Both viruses are very stable and can survive for a long time on hands, cutting tools and other surfaces. Aphids and thrips can spread other viruses that frequently infect orchids.

Viral symptoms in orchids vary greatly from cultivar to cultivar, and even from plant to plant. Some typical symptoms on leaves include brown, black or yellow spots or streaks; ringspots and mosaic patterns. Some symptoms that may be evident on flowers are distorted shapes, brown streaks and color break.
