Leaf Spot – On Turnips and Mustard

Q: I have these spots on my mustard and turnip leaves . I ‘d appreciate if you could help me get rid of what is causing them so I could get some in the freezer.

A: I think it’s cercospora leaf spot. Copper-containing fungicides like Kocide 101 (click for sources) seem to be the only products labeled for leaf spot on mustard.
