Colombian datura virus

The Colombian datura virus (CDV) was detected in Brugmansia sp. plants in New South Wales in 2007. Subsequent surveillance of Brugmansia plants in Victoria in 2007 detected the virus in a nursery in a variegated species.

The distribution of this virus in Australia is still unclear as affected plants may be asymptomatic, which makes the detection and spread potential difficult to predict. It's also unclear what effect this virus may have on other crops in Australia.

Symptoms of CDV

Symptoms of CDV can include:

  • reduction in leaf size
  • vein banding
  • chlorotic flecking on leaves followed by mottling
  • plant stunting.

Infection can be symptomless, but if plants are stressed, leaf mottling and mosaic patterns will become evident.

If you suspect CDV

Report any unusual plant pest or disease immediately to the Exotic Plant Pest Hotline on 1800 084 881. Early reporting increases the chance of effective control and eradication.

Alternatively, you can make a report via our online form with a photo (where possible).

Host plants

CDV affects:

  • angles trumpets Brugmansia species
  • terrestrial orchids (Spiranthes cernua)
  • gold finger Juanulloa aurantiaca
  • Petunia hybrida
  • glasshouse tomatoes (Lycopersicon esculentum)
  • tobacco (Nicotiana tabacum)
  • cape gooseberry (Physalis peruviana)
  • pepino (Solanum muricatum)

Leaf symptoms showing faint chlorotic spots

Spread of virus

The virus is transmitted by:

  • a vector (aphid nonpersistent transmission by Myzus persicae [order Hemiptera])
  • mechanical inoculation
  • grafting.

(Salamon 2005)

CDV in other countries

In 1996, CDV was detected in about 300 plants of tomato variety Cabrion in one greenhouse in the Netherlands. Evidence was obtained that the tomato plants were infected by Myzus persicae that acquired the virus from a CDV-infected Brugmansia plant in the same greenhouse (Verhoeven 1996).

In Hungary, CDV has been found to infect angel trumpets (Brugmansia spp.) frequently and cape gooseberry (Physalis peruviana) and pepino (Solanum muricatum) sporadically. The symptoms persist or disappear soon after infection (Salamon 2005).

The virus known to occur in:

  • Canada
  • Colombia
  • Germany
  • Hungary
  • India
  • Japan
  • Netherlands
  • Poland
  • United States of America
