More than 20 viruses have been reported that can pose a major constraint to sweetpotato production. Current diagnostic tests available for sweetpotato viruses are either not sensitive enough to reliably detect viruses directly from sweetpotato or require expensive laboratory equipment to perform and a high level of experience. We demonstrate that LAMP can be deployed in a non-laboratory situation, such as in a field setting for use during inspections for seed certification or incidence surveys.
