I've read quite a few unbiased oat fungicide trials and the conclusion from most are that fungicides on average do not pay in oats. It seems varieties with poor or no resistance to crown rust (i.e. ac morgan) often have positive responses to fungicides in yield, test weight, plumpness. Note that most of the trials either are studying crown rust control or occur in dryer climates. Fungicide applications were mostly positive in the "normal" oat growing areas such as Melfort.
If you've decided to apply a fungicide, there are a few options.
Propiconazole (tilt) is entry level, cheaper and does a good job
Acapela, Quilt, Topnotch, Twinline are medium priced and have always delivered a worthwhile return. The strobilurins do have some additional benefits such as improved straw strength.
The top level is Trivapro. (Prosaro or Caramba are pretty expensive for oats). 3 modes of action and 3 weeks of protection versus up to 2 weeks anything else.
