To determine the effectiveness of weed seed set control strategies in driving down the seedbank without reducing yields in cereal-intensive cropping systems.
Key messages
A combination of chemical and non-chemical weed control strategies can extend the life of herbicides and improve the sustainability of intensive cropping systems.
Windrow burning, crop topping and chaff carts are options which can reduce the ryegrass seed bank without any yield penalty.
Cutting a cereal crop for hay for one year can significantly decrease ryegrass levels in the following crop.
