Welcome to the home of TASKFORCE® Herbicide
This site provides information on the use and properties of TASKFORCE® in the control of certain weed grasses in pastures. These grasses include:
- Serrated Tussock
- Chilean needle grass
- Giant Parramatta Grass
- Giant rats tail grass
- African lovegrass
TASKFORCE® is manufactured by Vee Dri (Aust) Pty. Ltd and was approved for sale in Australia by the National Registration Authority (now the Australian Pesticides and Veterinary Medicines Authority) in July 2000.
The active ingredient in TASKFORCE® is sodium 2,2,3,3 tetrafluoropropanate. TASKFORCE® is unique as it will selectively kill the above weed species without devastating many other desirable pasture species. TASKFORCE® is a systemic herbicide with low contact activity as it is mainly taken up by the roots where it is translocated to other parts of the plant. This process begins after a minimum of 5 mm of rain. The herbicide acts very slowly and the first signs of the weeds dying may take up to 3 months - just dependent on factors such as soil type, rainfall etc. A major benefit of this herbicide is its ability to keep killing germinating seedlings for 3-4 years after initial treatment.
