This study was undertaken to determine the optimal timing for fungicide application during the growing season to reduce Sclerotinia development.
• Sclerotinia stem rot levels were reduced with a single foliar fungicide applied at 10% and 30%, and multiple applications at the 30% and 50% bloom stages.
• Multiple applications at the 30% and 50% bloom stages had the most significant effect in reducing disease.
• Significant yield benefits were measured when multiple fungicide applications were applied during the growing season.

Fungicide |
Prosaro® 420 SC (450 mL/ha) was applied at nine different timings according to specific growth stages (% bloom), and the combination of growth stages and rainfall events (% bloom– strategic). Single fungicide treatments were applied at 10%, 30%, 50%, and above 50% (late fungicide application – LFA) bloom stages. A multiple fungicide treatment was applied at both 30% plus 50% bloom stages. Strategic treatments were applied before rainfall events at growth stages 10%, 30% and 50% bloom stages. A single 48-hour treatment was included based upon estimating a prolonged period of wet weather given the available forecasts. Nil treatment |
Seed treatment | Seed was treated with Jockey® and sown with Impact In-Furrow®-treated fertiliser. |
