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.
ï‚· 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.
ï‚· 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.
ï‚· All treatments (except for Maxim XL followed by Miravis Star) were higher yielding than the untreated control.
ï‚· There was no effect of fungicide treatment on oil concentration.
ï‚· 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.
