Fluid delivery systems and fungicides in wheat locations
Aims

To build on previous research by updating knowledge of the benefits, including disease control and nutrition, of fluid delivery systems. 

 

Key messages
  • In 2016 there was a small yield response to phosphoric acid over granular P at Warramboo.
  • Fungicides and the addition of extra 40 kg/ha urea at seeding separately reduced Rhizoctonia seminal root infection compared to the control at both sites.
  • Including fungicides will increase input cost and risk over a cropping program.
  • The addition of a trace element mix or manganese did not improve yields at Streaky Bay or Warramboo.

Warramboo 2016

Sow rate or Target density sown at 60 kg/ha of Mace wheat
Sowing machinery

The fluid fertiliser delivery system placed fluid fertiliser approximately 3 cm below the seed at an output rate of 100 L/ha. The fungicide fluid system split fluids both below the seed at approximately 3 cm, and in the seeder furrow behind the press wheel in a 1 cm band width.

Sow date 26 May 2016
Harvest date 23 November 2016
Plot size 2m x 20m
Plot replication 3
Fertiliser

The control treatment was 60 kg/ha of Mace wheat with 50 kg/ha of 18:20:0:0 (DAP). All phosphorus treatments were applied to the same rate of 9 units of phosphorus (P) and balanced with urea or UAN to 10 units of nitrogen (N). Manganese (Mn) was selected as the main focus trace element, with zinc (Zn) and copper (Cu) also included in the trace element mix. A DAP fertiliser dry blend with Mn @ 1.5 kg/ha was used. Phosphoric acid and granular urea, and ammonium poly phosphate (APP) and urea ammonium nitrate (UAN) were used as fluid fertiliser products to compare with granular fertilisers. Manganese sulphate was dissolved with the standard rate being 1.5 kg Mn/ha and 3 kg/ha as a high rate. 1 kg/ha Zn, as zinc sulphate and 0.2 kg/ha Cu as copper sulphate were dissolved in the standard rates of trace elements, which were also delivered as foliar applications at 4-5 leaf stage on 14 July in Streaky Bay and 21 July at Warramboo. The extra nitrogen at seeding treatment was applied as

Herbicide

Herbicides were applied and included 1.5 L/ha of trifluralin, 2 L/ha of glyphosphate and 80 ml/ha of carfentrazone-ethyl and a wetter. All treatments were sprayed on 28 June with tralkoxydim at 500 g/ha, clopyralid at 75 ml/ha, sulphate of ammonia at 800 g/100 L and paraffin oil, to control weeds in-crop. Snail bait was also applied.

Insecticide

In-crop pest control on 1 July included 1 L/ha of flumetsulam, 750 ml/ha of chlorpyrofos insecticide and snail bait.

 

Fungicide

The fungicides azoxystrobin + metalaxyl-M (Uniform), penflufen (new formulation of EverGol Prime) and sedaxane (Vibrance seed dressing) were assessed for Rhizoctonia disease suppression at different rates and in split applications. Triadimefol and flutriafol were also applied on fertiliser as treatments.
