Cucumber virus alert
Karen OMalley, Horticulture Officer
It is really important local growers keep a look out for this, it has been devastating to NT growers!
Cucumber Green Mottle Mosaic Virus (CGMMV) was recently detected in watermelon crops in the Northern Territory. This is an exotic plant pest and a national biosecurity response is now occurring.
CGMMV is a plant disease that infects watermelon, cucumber, melons, zucchini, pumpkin, squash, bitter gourd, and bottle gourd. It is highly contagious and easily spread through a crop by plant contact, contaminated water, mechanical transfer, and even clothing and hands of workers pruning or moving in a crop.
The virus spreads to new areas through contaminated seed so it is important for NSW watermelon growers to be alert for symptoms of the disease as the season progresses. CGMMV causes extensive damage to the watermelon plants, resulting in substantial yield losses. CGMMV is not easy to control because it can survive in crop debris for many years.
If you suspect CGMMV in your crop, please report it by calling the Exotic Plant Pest Hotline on 1800 084 881. Reports can also be sent to NSW DPI by emailing email@example.com.
If emailing, include photos of the suspect plants and symptoms.
If you are unsure whether the symptoms you might be seeing are CGMMV, email firstname.lastname@example.org for assistance.
