Herbicide: 2,4-D amine (Group I) (various trade names: see APVMA link) | |
---|---|
Active ingredient | 500g/L 2,4-D amine |
Rate of dilution for spot spraying | 1:1000–1:670 |
Rate of product/ha | 1–1.5L |
Wetting agent | 1:600 |
Remarks | Burn paddock in late summer early autumn to increase sprouting of cormils and corms. Respraying at lower rates will be necessary for several years to exhaust dormant corms and cormils. Treatment will damage clover. |

Herbicide: 2,2-DPA (Group J) | |
---|---|
Active ingredient | 740g/kg 2,2–DPA |
Rates of dilution for spot spraying | 55g in 10L |
Rate of product/10L water | 55g |
Rate of product/ha | 5.5kg |
Wetting agent dilution | 1:600 |
Time of application | Full emergence to early August |
Remark and other control measures | This treatment is recommended only for early control. More expensive than 2,4-D. Use in non-arable areas only. Useful for areas that become boggy later in winter. Can also be useful in bushland treatments.

Wetting agent dilution | 1:400 |
Time of application | Wheat pre-sowing or post-emergence. Barley and oats post-emergence only. Control can be achieved from early emergence to flowering of the cape tulip. Less damage occurs to most non-legume components if applied late post-emergence. |
