The IPPC Standards Committee (SC) in November 2019 agreed to include this message on the potential for false positive results:
The described PCR methods may produce positive test results with P. paracitricarpa and P. citriasiana. In the event of a positive PCR test result, culturing of the fungus and multi-locus sequencing as described in Guarnaccia et al. (2017) is needed in order to achieve reliable identification of P. citricarpa.
