bit north of London, UK | Interestingly we have had Headline / Pyraclostrobin (Comet et al in UK) for a good while now.
Never used it on Canola - nor am i sure if it is even labelled for such...but that does not mean anything.
'Here' the benchmark for sclerotinia control is the active 'boscalid' as in our trade name 'Filan'.

i think Prothioconazole is also well rated, but i use filan.
Here we work on the assumption that if you can see the sclerotinia it is far too late to do anything about it. Must be prevented from getting a grip in the first place, which means an application is required in first half of flowering season.
Filan strong on Alternaria also, which means an application in second half of flowering season.
So two applications for the full monty protection, 50-60% label rate seems to do the job. Not cheap.
