A method for efficient inactivation Papper mild mottle virus (PMMoV) in harvested seeds of green pepper was examined based on the infectivity on the leaves of Nicotina glutinosa L.(a local host) and a reverse transcription and polymerase chain reaction (RT-PCR)-based amplification of the viral RNA. The seed homogenates from PMMoV-infected plants produced a large number of necrotic local lesion in N.glutinosa, but soaking the seeds in 10% (w/v) tri-sodium phosphate (Na3PO4) for 20 min or dry sterilization (70C,3h) effectivity eliminated the abundance of PMMoV. However, no necrotic lesion on N.glutinosa or the RT-PCR-basaed amplification was observed with seeds that has been disinfected by Na3PO4 in combination with dry sterilization.
