To determine the impacts of cultivar choice and fungicide management for disease infection and grain yield of hyper-yielding canola.
• The application of flowering fungicide Aviator Xpro at 20% bloom increased yield across all varieties compared to where no fungicide was used by 0.42 t/ha. This treatment was designed to determine the effect of late foliar diseases (sclerotinia and upper canopy blackleg) on canola yield.
• The addition of Saltro Duo to seed and Prosaro at 6-leaf stage (Complete treatment) increased yield by a further 0.23 t/ha.
• Despite differences in blackleg resistance ratings in this trial, all varieties responded to fungicide inputs in the same way.
• Oil concentration wasn’t affected by fungicide input but there were differences between varieties. Highest oil came from 45Y28 RR with 45.9% and lowest oil from ATR Wahoo with 40.5%.
