Beet leaf stalks have hard brown spots
Beet None Given
My beets have these symmetrical brown spots on the leaf stems. Leaves are fine, beets are fine. These spots are raised up (i.e. a side view will show a bump). Some look like the stalk's skin is unbroken, others have the stalk's skin broken and the center of the spot is solid. I can't find this issue on any forums. Any ideas? I didn't eat them (I like to eat the small beets steamed with the greens), but wondering if I can eat the next batch.

It can be many things, but from that single photo it looks like a scale (insect I wouldn't eat) or also looks like a rust (fungal disease), on this last one if you break it and it releases a reddish brown powder, yes, it is rust (Uromyces beticola) if not, probably you have a scale.

Looks like scale bug. Or could be scab. If scale scrape off and wash well. If scab rotate to new plot. over 6 years ago.
