Cucumber green mottle mosaic virus

Cucumber green mottle mosaic virus (CGMMV) is a plant disease which is exotic to Australia. CGMMV can result in substantial crop losses.

Report any suspected cases of CGMMV immediately to the Emergency Plant Pest Hotline on 1800 084 881.

The virus infects:

  • watermelon
  • cucumber
  • melons
  • zucchini
  • pumpkin
  • squash
  • bitter gourd
  • bottle gourd.

Symptoms can vary between plant species and the particular strain of the virus. They can also be difficult to diagnose without laboratory testing. The most common symptoms can be on the leaves or fruit.

Symptoms on leaves:

  • mottling and mosaic
  • blistering or bubbling
  • vein clearing
  • leaf distortion.

Symptoms on fruit:

  • often no external symptoms
  • spotted and distorted
  • internally discoloured and rotting
  • uneven ripening.

CGMMV does not pose any risk to human health.

There is no known cure for CGMMV. Preventing infection is the key to protecting the health of your crops. The virus can spread easily and can stay alive for an extended time in plant debris and soil and on vehicles, equipment and tools.

A significant risk of spreading CGMMV onto farms arises when:

  • propagation material
  • people
  • machinery and equipment

move from property to property and from region to region.
