Biosecurity alerts

What is plant biosecurity and why is it important?

Plant biosecurity is about protecting the growers, environment, and general public from plant pests and diseases. Being an island nation we are lucky to have a natural barrier to many pests and diseases entering the country. Quarantine and biosecurity measures help to reduce the risk and the impact of exotic pest and disease outbreaks. 

Some exotic pests and diseases have the potential to cripple our horticultural industries; plant biosecurity is important to ensure that we continue to grow, and the general public can buy Australian fresh produce. Fewer plant pests and disease mean lower production costs for our growers, less reliance on pesticides and greater market access nationally and internationally. It is important to help protect our industry from pests and diseases not just at a state level but also at a national level, so the movement of plant material within and across states is regulated by the Plant Biosecurity division. 

Plant biosecurity also helps to protect our environment. Not all exotic pests and diseases target commercial crops, some (like myrtle rust) affect native plants and cause significant decline in our natural parks and gardens. This has an environmental and social impact as it can cause the death of vulnerable trees, which provide habitats for animals and are used in ammenity plantings such as parks and gardens.

For more information on current outbreaks and restrictions visit the biosecurity webpage.


Banana Freckle

In 2013 a new strain of banana freckle was found in the NT that infects a wide range of banana varieties. Banana freckle will have a serious impact on commercial banana production and backyard plants if it becomes established in Australia. We can eradicate banana freckle, but we need to act now before it becomes more established, starts to cause more damage and spreads more broadly across the Territory and Australia. For more information about the program visit the Banana Freckle website


Cucumber Green Mottle Mosaic Virus (CGMMV) in the Northern Territory

The Cucumber Green Mottle Mosaic Virus (CGMMV) is a plant disease which until recently was exotic to Australia. The virus infects watermelon, cucumber, melons, zucchini, pumpkin, squash, bitter gourd, bottle gourd and some species of closely related weeds. For more information on CGMMV visit the CGMMV website
