There are numbers of viruses that affect pulses including field pea:

  • AMV - alfalfa mosaic virus
  • CMV - cucumber mosaic virus
  • PSbMV - pea seed-borne mosaic virus, (Figure 7.17)

What to Look For

The general symptoms of virus affected plants are yellowing and stunting. There may be extra symptoms caused by specific viruses. Please refer to the Viruses chapter 10 in the manual for more details.


Selection of high quality seed is important. A number of common viruses are seed-borne. These viruses include alfalfa mosaic virus (AMV), cucumber mosaic virus (CMV), pea seed-borne mosaic virus (PSbMV) and bean yellow mosaic virus (BYMV). Purchase virus-tested seed or have the farmer seed test for viruses (see Seed Health Testing in Pulse Crops). Refer to Viruses chapter 10 for more details.
