Management of Ryegrass in the High Rainfall Zone (HRZ)
Annual ryegrass can be particularly challenging to manage in the high rainfall zone (HRZ). Widespread resistance to post-emergent herbicides used in cereals means there is strong reliance on pre-emergent herbicides for ryegrass control. Annual ryegrass seed banks in the HRZ tend to be high and there is late emergence of weeds due to the long and cool growing season. These late emerging plants contribute to high seed set that maintains populations. As a result, ryegrass populations quickly rebound when management pressure is reduced. Late maturity of cereals means that 50% or more of the ryegrass seed can be shed prior to harvest, reducing the efficacy of harvest weed seed controls. On the plus side, moderate populations of ryegrass (<100 plants per m2) have less impact on yield than they do in other regions.
This project aims to demonstrate annual ryegrass management strategies in the HRZ, providing confidence for agronomists and growers to make on-farm management changes that are effective and profitable.
- Five demonstration sites have been established across southern Victoria and the SE of South Australia.
- Sites are sown to break crops in 2018 and will have wheat in 2019.
- Each site has 4 annual ryegrass management strategies with increasing management intensity to demonstrate strategies that may provide effective and profitable management of annual ryegrass in the HRZ.
- The management strategies employed at each site have been developed with local agronomists.
- There will be opportunities to view the sites during the season.
Plot plans, treatments and data collected at each site is available via the HRZ ryegrass management portal.
