Fluid Delivery of Fungicides and Fertilisers for Canola locations
Aims

SAGIT funded a project to assess the potential of fluid nutrient delivery systems and disease control strategies compared to current systems. Fluid systems have the potential to increase production through more effective delivery of micro and macro nutrients, use of lower cost trace element sources and improved control of cereal and canola root and leaf diseases.

Blackleg continues to be a major issue facing canola growers especially on lower Eyre Peninsula and fluid delivery systems for fungicides may increase production and improve disease control. With the development of new fungicides and the technology 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. These trials compared the relative benefits of a range of fungicide strategies for blackleg control on canola compared to current practices.

Key messages
  • Intake (on fertiliser) and Jockey (on seed) is current standard practice for lower EP canola and reduced Blackleg stem infection. In 2014 this practice also increased grain yield. This remains the recommended practice.
  • The application method for the fungicide, either as seed treatments or in-furrow, did not increase canola yields in 2015 or 2016.
  • The source of nutrients and application method, either fertiliser, in-furrow or foliar had no effect on canola yield in 2014, however further research should be undertaken in this area before final conclusions are drawn.

Fertiliser

In each season the base fertiliser was 100 kg/ha of DAP (18:20:0:0) with additional in-furrow fungicides or trace elements delivered as fluids for treatments. The trace element mix was 1.5 kg/ha of Mn, 1 kg/ha Zn and 0.2 kg/ha Cu delivered as sulphates at a water rate of 100 L/ha. The full macro fertiliser treatments were equivalent to 100 kg/ha of 18:20:0:0 as phosphoric acid and granular urea banded below the canola seed variety Pioneer45Y86 (CL). Trace elements were also delivered as foliar applications at 4-5 leaf stage and also at a half rate, as separate treatments.

Fungicide

The fungicides evaluated for blackleg disease control were Jockey and Intake in all seasons, and new products Aviator and Prosaro in 2016 only. Application methods of fungicides were also assessed; either in-furrow liquids, Jockey as a seed dressing or Intake on fertiliser. In 2016 foliar Aviator and Prosarp were also applied at 400 ml/ha and 550 ml/ha respectively at the 4 leaf stage.
