Cucumber Mottle Mosaic Virus (PUB14 287)

An incursion of the plant disease Cucumber green mottle mosaic virus (CGMMV) was reported in a watermelon crop in the Northern Territory in late October 2014. Since then several melon farms in the Darwin and Katherine area have been confirmed as having CGMMV.

The Northern Territory Department of Primary Industry and Fisheries has put into place strict containment strategies and control measures for the movement of watermelons out of the controlled areas. The intent of the National Management Group for Exotic Plant Pests is to have a containment and possible response plan enacted to eradicate the disease from Australia.

The NSW Department of Primary Industries (DPI) has also introduced legislation in line with other jurisdictions limiting the movement of watermelon and other cucurbit host plants, plant material, soil that has contained host plant material, used equipment and packaging.

Producers are encouraged to be vigilant of existing crops and also be aware of the possibility of introducing infected plant material, machinery or packaging to their properties.

While NGI is an "affected party" under the Deed we are not directly involved and our members (growers of plants) are not destroying crops etc.

  • Virus is thought to be seed borne (yet to be confirmed)
  • We do not know how many seeds are in the country and where they are from.
  • Govt has strengthened testing requirements for cucurbit seed prio to importation effective 22 Oct.
  • Other States have been requested to do trace testing but no results as yet.
  • Pathogen is relatively widespread overseas and has had major impacts on crops.
Please consider where you are obtaining seeds from the Cucurbit family and sourcing plants from areas known to be infected, ie Northern Territory.

For any more information please contact Michael Danelon, NGINA IDO.
