Disease management for Hyper-Yielding Canola locations
Aims

To determine the impacts of cultivar choice and fungicide management for disease infection and grain yield of hyper-yielding canola.

Key messages

• 45Y95 CL was the highest yielding variety across all fungicide treatments, averaging 3.65 t/ha.
• The Flowering and complete fungicide treatments yielded similarly, both yielding more than where no fungicide was applied. This indicated that the fungicide response was due to the control of late foliar diseases (upper canopy blackleg and/or sclerotinia stem rot).
• Varietal crown canker blackleg response to fungicide application varied but there was no interaction between fungicide treatment and variety for yield or quality.
• Hyola Solstice CL had very low incidence of crown canker blackleg but was the lowest yielding variety overall. 45Y95 CL had the most crown canker blackleg infection where nil fungicide was applied but this was greatly reduced where fungicide was applied. Yield did not appear to be affected by the level of blackleg in 45Y95 CL.
• 45Y28 RR had the highest oil concentration of the varieties but there was no impact of fungicide strategy on oil concentration.

Event Date Type Effect
Hail

Hail damaged the trial site in the early hours of Monday 12 December, leading to considerable pod damage and seed loss in the ripe spring types. Winter types still had green pods and were not affected.
