Risk factors

 

The development of PVM infection results from a combination of: 

  • different sources of infection, either internal (volunteers, seed tubers, weeds) and/or external (nearby potato crops, gardens, weeds); 
  • the relative significance of flights of aphids during the growing season (related to climatic conditions and nearby crops);
  • the level of control measures taken in seed potato production (roguing, crop management such as weed control, crop protection, haulm  destruction and field and/or lot inspection);
  • the susceptibility of the potato cultivar.
