When green pepper seedlings were transplanted to soil mixed with roots infected with pepper mild mottle virus (PMMoV), the mosaic disease developed. This suggested that infection by PMMoV occurred at the time of transplanting. Green pepper seedlings were transplanted to infested soil by several methods to investigate the possibility of preventing soil transmission. Consequently, removing seedlings from their pots and transplanting to soil had an incidence of approximately 80% diseased plants. Plants removed from the seedling pots had exposed roots that were easily contacted by infested soil when transplanted. On the other hand, molded peat-moss pot seedlings transplanted to soil had an incidence of 0-14% diseased plants. The reduction in disease incidence is attributed to the peat-moss pot preventing contact of seedling roots with infested soil at the time of transplanting. Since the molded peat-moss pots had no adverse influence on the growth of green pepper seedlings after transplanting, it appears to be an effective method for preventing soil transmission of PMNIoV.
