To asses the effects of fungicides for sclerotonia management in canola.
Prosaro Fungicide was the best option for reducing Sclerotinia disease pressure during the season. The treatments were applied at 50% Flowering, before any petal drop had occurred. The return on investment was still very good, with Pro-saro returning an additional $116/ha above the untreated control. Perhaps a larger response to fungicides would have been evident if the sprays had been applied at 20-30% flowering, as infection was very evident before spraying. The Rovral fungicide treatment was disappointing in this trial.
