Description :

Banana Bract Mosaic Virus, BBrMV, belongs to the Potyvirus genus. It is transmitted through aphids and colonises the plant from the point of penetration, going through the roots and the main meristem, rapidly becoming systemic. Transmission occurs from infected plant material. This is a regulated disease subject to mandatory measures to control it.

Symptoms :
  • Appearance of a brown mosaic on the bracts.
  • Possible discolouration of the pseudostem.
  • The fruit also presents significant green/yellow mosaics.
  • Occasionally, whitish spindle-shaped lines may be observed on the blades of young leaves.
Method : IC – RT – PCR
Matrix :
  • Fresh young leaves (with central vein) or freeze-dried leaves
  • Bracts
Description :

Cucumber Mosaic Virus is a pathogen phytovirus from the Cucumovirus group belonging to the Bromoviridae family.

The virus is capable of growing in a great many host plants, both cultivated and wild. It is transmitted through several species of aphids.

Symptoms :
  • Chlorotic mosaic, possible very pronounced, on young leaves and veins.
  • Deformation or even shrivelling of the leaves in severe cases.
  • Reduced growth and altered shape of the plant.
  • Mosaic on fruit.

A plant infected by this virus remains a carrier until it dies.

Method : ELISA
Matrix :
  • Fresh young leaves (with central vein) or freeze-dried leaves
  • Pseudostem
