About cucumber green mottle mosaic virus
What the virus affects
The virus attacks plant cells through minute plant wounds.
It infects watermelon, cucumber, melons, zucchini, pumpkin, squash, bitter gourd, and bottle gourd – long melon – and some other species.
There are at least five strains of the virus, and symptoms can vary between hosts.
Other mosaic diseases, caused by potyviruses, are known to occur in northern Australia and can cause similar symptoms. This makes it difficult to identify it by sight. It can only be conclusively established by laboratory testing.
