Why do the trial?
A SAGIT Fluid delivery project was funded to update the benefits of fluid delivery systems from previous research and assess the potential of fluid nutrients and disease control strategies in current farming systems. The fluid systems (fertilisers or nutrients) have the potential to increase production through delivery of micro and macro nutrients, reduce cost of trace element delivery, and increase control of cereal root and leaf disease, resulting in possible increases in dry matter production and grain yield.
Historically, fungicidal control of Rhizoctonia which infects the major crops grown in southern Australia has generally been poor but fluid delivery systems with fungicides are a new option of delivery which may increase production and improve disease control. With the relatively recent development of processes to evenly coat fertiliser granules with fungicides and to deliver liquid products around the seed row during the seeding pass, there is now a range of application strategies available to growers to make use of these new products. This trial was undertaken to assess the benefits of these products, and various application strategies, on wheat in two upper Eyre Peninsula environments.
