New Pre Emergent Grass Weed Control Herbicides in Triazine Tolerant Canola locations
Aims

To examine pre-emergent grass weed control herbicides in triazine tolerant canola

Key messages

• Ryegrass is an increasingly significant weed in the SE of SA and Western Victoria due resistance to major knockdown, pre emergent and post emergent herbicide chemistries.
• As resistance develops to post emergent chemistry, pre emergent chemistry becomes increasingly important in managing resistant ryegrass.
• Knowing the resistance status of weeds within a paddock allows for the most cost effective herbicide to be applied....the most expensive herbicide is the one that doesn’t work.
• Incorporating alternative herbicide modes of action can improve ryegrass control especially where the presence of Group D resistant ryegrass is suspected or known.
