Pacific Pests, Pathogens and Weeds


  • Worldwide distribution. On edible aroids, and many ornamental types. A common virus disease with minor impact.
  • Feather-like, light green or grey patches, often along the veins, confined to one area or throughout the leaf, sometimes causing distortions at the margins.
  • Spread is by aphids; they suck sap from diseased plants, contaminate their mouthparts, fly or are blown in wind to healthy plants and infect them as they feed again. However, ability to infect is lost quickly.
  • Cultural control: there are no practical measures.
  • Chemical control: not appropriate for viruses spread quickly by aphids in this way. The aphids have spread the viruses by the time they are killed by the insecticide.
