Risk factors

 

The development of PVY infection results from the combination of different sources of infection, either internal (volunteers, seed tubers, weeds) or external (nearby potato crops, gardens, weeds such as Solanum dulcamara or Datura spp.), the 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 or field and lot inspection) and finally the level of the susceptibility of the grown potato cultivar.
