FIREWEED - NOW IS THE TIME TO TREAT |
|
|
|
April is the time to begin your Fireweed (Senecio madagascariensis) treatment plan, as the best method of control is prevention. Seed is long lived in the soil and is produced in large quantities so any small infestations must be addressed immediately to stop the situation from becoming worse.Fireweed is a weed of national significance and can be identified by:
- Daisy-like yellow flowers.
- Bright green narrow leaves with serrated, entire or lobed margins.
- Leaves usually 2-6cm long and clasped around the stem.
Keep in mind that the appearance of Fireweed can vary depending on the conditions it is growing in. Fireweed can be treated with foliar spray using;
- Grazon Extra Herbicide at a rate of 500mL/ 100L of water.
- Hotshot Herbicide at a rate of 350mL/100L of water.
Early identification is vital to ensure you carry out an effective treatment program. Continual spot spraying and observation is necessary as it is during Autumn that Fireweed germinates.
Other weeds that should be treated in April include Lantana, Blackberry, Eucalypt and Wattle regrowth, Gorse and Prickly acacia as indicated by the table below.

THINLINE APPLICATION TECHNIQUE SAVES TIME AND MONEY |
|
|
ThinLine Application is an application technique using Access herbicide to treat saplings and regrowth less than 5 cm in basal diameter.The herbicide is applied mixed with diesel or Biosafe, a diesel replacement, to assist penetration through the bark. Always refer to the product label for details.The ThinLine application method, requires a mix of Access with diesel or Biosafe at a ratio of 1:9.
You treat the stem of the sapling from ground level up to 5 cm high. This technique uses less carrier and reduces the time required to treat each stem compared to standard basal bark application.

In this case less to retreat. Generic formulations of picloram/triclopyr are based on the original Grazon™ DS formulation. Now Grazon DS has been superseded with Grazon™ Extra, which contains triclopyr picloram plus the new highly active product called aminopyralid.
Aminopyralid is an extremely active ingredient at relatively low concentrations. It has been proven to enhance the activity of Grazon Extra on weeds previously covered on the old Grazon DS label as well as an increased number of weeds that can now be reliably controlled with a single herbicide treatment of Grazon Extra.
According to Ross Watson, Consulting Agronomist, he believes “Yes on first appearances the generic looks like a good buy, with a saving of $200/drum.
But in woody weed control programs, the decision of what product to buy “should not be based on the cost of a drum of chemical” but on the reliability of results that can be achieved at recommended rates of application. The cost per drum is a misleading measure of results. From my experience, the reliability of results is paramount when one commits to a woody weed control program, often in difficult terrain, during the summer months.”
Your labour and time is a bigger cost
According to Ross Watson, “For a typical woody weed spraying job, the time and labour costs account for more than 50% of the cost of treating woody weeds and is often 60–70% of the treatment cost.”
Why Grazon Extra?
- You will need a third less Grazon Extra than generic picloram/triclopyr to do the job.
- The aminopyralid in Grazon Extra provides you with more control
- You will spend less time in the paddock in the long run
