Disease management for hyper-yielding canola locations
Aims

To determine optimum foliar fungicide management for hyper-yielding canola.

Individual objectives specific to the trial are:

Determine the value of contrasting major gene blackleg resistance groups in HYC
environments:
a. BC (45Y28 RR and 45Y93 CL) – largely ineffective major gene resistance (good minor
gene resistance).
b. ABD (HyTTec Trifecta) – currently effective major gene resistance.

Determine the effect of fungicide management strategies on disease control (upper canopy
blackleg and sclerotinia), grain yield and profitability.

Key messages

 The Roundup Ready cultivar 45Y28 RR was consistently higher yielding than the TT cultivar HyTTec Trifecta.
 Disease levels were low overall, with only low-level blackleg observed. Although 45Y28 RR does not have effective major gene blackleg resistance, it did not have more blackleg infection than HyTTec Trifecta.
 Aviator Xpro and Miravis Star at 20% bloom, both followed by Prosaro at 50% bloom, were higher yielding than the untreated control, but by less than 0.25 t/ha which would have not been profitable.
