In this edition of AHRI Snapshots, we’re speaking with Director of Weed Research at the Plant Breeding Institute, University of Sydney, Michael Walsh about a recent research paper on crop competition and its influence on harvest weed seed control on ryegrass. We know crop competition is great at suppressing weeds, but what we have learned from this research is that crop competition makes other weed control techniques, such as harvest weed seed control work better. This research was published in the paper “Influence of Crop Competition and Harvest Weed Seed Control on Rigid Ryegrass (Lolium rigidum) Seed Retention Height in Wheat Crop Canopies”. Our Southern Extension Agronomist Kirrily Condon recently did AHRI insight on this topic too.
