The aim of this work is to understand if growers can reduce soil weed seedbanks in high-yielding high-rainfall zones by adopting harvest weed seed control (HWSC) practices.
• Herbicide-resistant annual ryegrass (Lolium rigidum) is increasingly becoming a challenge for growers across southern Australia.
• Harvest weed seed control (HWSC) — the collection and/or destruction of weed seeds at harvest — is a non-chemical control method, which can be used to reduce the seedbank of weeds such as annual ryegrass.
• A major premise of HWSC is that the targeted weed species retain a high proportion of their total seed production at crop maturity.
• Where pre-emergent or in-crop herbicides have not been applied, ryegrass weeds are shedding before wheat is harvested.
