The trial was sown on the 19th of May in Beacon, WA. The site has a history of crown rot.
Immediately Pre-seeding – 19/5/2020: Treflan 1.5L, Ammonium sulphate 1%, Diuron 900 WDG 180g/ha, Sakura flow 210ml/ha, Pyrinex super Insecticide 250ml/ha.

Emergence ratings at assessments 14 & 28 DAS.
Crown to first node discoloration incidence and severity, percentage (%) of browning Mid grain fill (10/9/2020)
Crown discoloration incidence/plot 16 WAS
- Emergence counts conducted at 14 & 28 DAS saw no significant differences between treatments (P>0.05).
- Crown to first node discoloration incidence and severity percentage ratings were low due to a lack of disease in the crop.
- Crown discoloration was observed only in the untreated, Vibrance 360ml/100kg and Rancona Dimensions 320ml/100kg.
- SD seed treatment stand alone at 1x, 2x and 3x rate as well as SD 1x + Vibrance all compared well to standards in the control of crown rot.
- The addition of Vibrance to SD improved disease control.
