Herbicide resistance is a major threat to cropping systems worldwide. Many herbicides previously used for weed control, have failed or are failing to provide adequate control of major grass and broad-leaf weeds. Annual ryegrass (Lolium rigidum) is one of these problematic weed species, which has developed resistance to a number of pre and post-emergent herbicides, across multiple herbicide groups (modes of action).

My current PhD research will aim to provide better understanding of resistance development in L. rigidum to pre-emergent herbicides in the Group J (thiocarbamates) family, including management strategies for grower implementation.

This research will also aim to investigate metabolic type resistance, more commonly referred to as NTSR (non-target site resistance) which is a major threat to current and future herbicides. The development of cross-resistance across multiple herbicide groups within L. rigidum populations, is a threat to herbicides currently registered and herbicides not yet discovered.
