Because of the wide array of symptoms that occur in different hosts, diagnosis of PLRV must be done based on the infected species. In potatoes PLRV is diagnosed by stunting and leafroll. Diagnosis of other species mentioned previously is by the above-mentioned symptoms. PLRV can be detected on site using PLRV AgriStrip-magnetic. This lateral flow test uses microbeads coated with an anti-body specific to PLRV. Virus particles are separated from the plant tissue using a powerful magnet. The PLRV AgriStrip-magnetic can detect low titers that were previously thought to be too low for traditional lateral flow tests.
