Other trial notes |
Onion Weed (Asphodelus fistulosus) management options in no till cropping, low-input rangeland grazing systems and other non-cultivated areas are often limited to hygiene practices, reduced total grazing pressure and chipping or spot spraying to prevent or delay new infestations. As part of the Maintaining Profitable Farming Systems with Retained Stubble initiative, funded by the Grains Research and Development Corporation (GRDC), the Upper North Farming Systems Group has investigated a range of onion weed control options to reduce the need for cultivation. |
