Giant rat's tail grass management videos

Giant rat's tail grass (GRT) is a restricted invasive plant native to Africa. This aggressive grass is found from northern Cape York to the New South Wales border and can reduce pasture productivity and significantly degrade natural areas.

Landholder's must manage the impacts of giant rat's tail grass on their properties.

Gladstone Regional Council and the Department of Agriculture, Fisheries and Forestry (DAFF) have partnered to create two videos, one on managing the seed spread of giant rat's tail grass and the other on the use of herbicides to treat giant rat's tail grass.

Seed spread and other management options

This video looks at why GRT is hard to manage, how to minimise the risk of it establishing, how long it takes for seed to pass through cattle, how to minimise its spread, whether fire can be used as a management tool and if fertiliser increases its palatability.

The video runs for 8 minutes and 33 seconds.


This video covers registered herbicides to treat GRT, the best time of year to apply these herbicides, how long you should wait between spraying and sowing new pasture, the effect of fire on herbicides and the role of glyphosate.

The video runs for 17 minutes and 30 seconds.

More information about giant rat's tail grass, including how it is spread, prevention and control methods can be found on the Business Queensland website.
