Sowing seeds for the future: The need for on-site plant diagnostics.

Point-of-care technology is a term used to describe any treatment given at the "site-of-need". The span of point-of-care has broadened, growing from its current dominant usage in clinical settings to encompass many sectors, such as water and food testing. This review focuses on applications of point-of-care/use technology in phytodiagnostics, a field which requires accurate diagnostic systems with increasing urgency due to the demands of global food needs in conjunction with persistent crop loss due to pathogens and increased awareness of the environmental impacts of extensive agrochemical usage.
