Grass weed management in retained stubble systems - farm demonstrations

The GRDC ‘Maintaining profitable farming systems with retained stubble’ projects on upper and lower Eyre Peninsula (EP) aim to improve farm profitability while retaining stubble in farming systems. Grass weed management is one of the key issues of current cropping systems with annual ryegrass and barley grass being of most importance on lower EP (LEP) and upper EP (UEP) respectively. Herbicides continue to be the main strategy for weed control, and on LEP the intensification of cropping rotations and the decrease in livestock from farming systems has resulted in even further pressure on herbicides, resulting in the accelerated development of herbicide resistance in ryegrass.

 

An integrated approach to weed management (IWM) is required to slow the development of herbicide resistance and improve the sustainability of our farming systems. IWM aims to lower the weed seed bank with the use of herbicides as well as non-chemical techniques such as cultivation, higher sowing rates, and harvest weed seed management such as burning stubble, narrow windrow and chaff cart dumps. Demonstration paddocks were monitored to assess grass weed management strategies in current farming systems. This information will be used to improve the Ryegrass Integrated Management (RIM) model for EP systems, and potentially produce other grass weed management models (barley grass).

Survey of invertebrate pests and beneficials harbouring in harvest weed seed control system

There are three non-burning and non-mechanical techniques most commonly employed in harvest weed seed control (HWSC) systems: chaff dumping, chaff lining and chaff tram-lining. The highest adoption of HWSC is in the GRDC western region with an estimated 67% of all farmers undertaking at least one HWSC strategy in 2014.

Chaff dumping is the collection of the chaff fraction using a cart towed behind the harvester. The chaff in the cart is then dumped, usually in piles in the paddock. The chaff is then either burnt, grazed or left to decompose.

For chaff lining, the chaff and weed seeds are confined to a row directly behind the harvester using a narrow chute. The chaff and weed seeds are then left to decompose over time. To promote decomposition, the chaff lines need to be placed in the same location year after year by running the harvester on a controlled traffic system (CTF).

Chaff tramlining is a similar concept to chaff lining, but the chaff fraction is diverted from the chaff deck onto permanent wheel tracks in a CTF system. Wheel traffic creates a hostile environment that inhibits weed seed germination.

There has been a recent system change with more growers opting for leaving chaff in-situ to rot, whether in dumps or in lines, rather than burning. This investigation aimed to better understand invertebrate species and mice associated with these HWSC systems, which to date are poorly understood, in each of the five port zones: Albany, Esperance, Geraldton, Kwinana’s East and West.
