Disease management for hyper yielding spring canola locations
Aims

To determine optimum foliar fungicide management for hyper-yielding spring canola. Determine the effect of fungicide management strategies on disease control (upper canopy blackleg and sclerotinia), grain yield and profitability.

Key messages

 Grain yield increased by 0.78t/ha from nil fungicide to where an intensive fungicide program was applied, including Saltro Duo on seed, Prosaro at 6-leaf, Aviator Xpro at 20% bloom and Veritas at 50% bloom.
 Highest yields were generally achieved with Seed and 6-leaf fungicide (Maxim XL f.b. Aviator Xpro of Saltro Duo f.b. Prosaro) followed by an application of fungicide (either Prosaro or Aviator Xpro) at 20% bloom. This suggests the response was due to the control of multiple diseases.
 All treatments (except for Maxim XL followed by Miravis Star) were higher yielding than the untreated control.
 There was no effect of fungicide treatment on oil concentration.
 It was difficult to ascertain the reasons for the yield response to fungicide as blackleg (upper
canopy and crown) and sclerotinia infection levels were low.
