Disease management for hyper yielding spring canola locations
Aims

Determine the effect of fungicide management strategies on disease control (primarily blackleg and sclerotinia), grain yield and profitability in 45Y28 RR (moderately resistant, blackleg group BC) and HyTTec Trifecta (Resistant, blackleg group ABD).

Key messages

 Blackleg crown canker (measured as stem cross-section blackleg) was generally highest (in both trials) where no seed or 6-leaf (seedling) fungicide was used, however there was no effect of fungicide management on grain yield.
 There was minimum upper canopy blackleg and sclerotinia disease in both trials.
 Oil content difference was minimum between the fungicide treatments.
