Girdled tomato stems
 

Tomato stems girdled near the ground, perhaps 1" in extent. Plant
wilts. Roma and Scotia both affected.

No detectable efflorescence of fungus aound the damaged area, no
visible tiny tooth marks. Plants are otherwise healthy and
flourishing when this happens. Plants affected are not all neighbors.

If I heap garden soil up around the stem to 3 or 4 inches above the
damage and give them plenty of water, they survive and most of them
recover to bear fruit despite a week or more of stagnation in growth.

Any idea what's causing this and what may be done to prevent it?

Look up cutworms.

Look up cutworms.

....and put paper collars around the stems to prevent.

Just did that. We've had problems long ago with cutworms chewing
tender seedings right off at the ground. Web info suggests that's
characteristic.

These are "teen-age" plants, in bloom or just setting fruit, with
quite sturdy stems. The damaged plants aren't cut off, just girdled.

Well, we do have an enormous variety and number of moths here so I
guess that's a candidate answer but the damage isn't, AFAICT, typical
of cutworm attack.

Tnx,

I lost a fairly mature eggplant transplant this year to a cutworm, which
managed to girdle the stem and weaken it to the point that it fell over
in the breeze. Absolutely was a cutworm, as I found it, squished it, and
flipped it at the nearest robin.

Plant ended up a total loss but since it was an extra I'd tucked in at the
end of the bed and was too close to the patch of Anthemis* I wasn't
that upset about it.

*I have various herbs and flowers in my vegetable garden mainly to attract
and feed bees and hoverflies. Anthemis tinctoria 'Kelwayi' is one of them.

The damage you describe occurs more frequently than one might
think. Cutworms also girdle branches/limbs and eat "channels" into
fruit, especially that touching or very near to the ground. Cutworm
damage to fruit often is mistaken for armyworm damage. Based on the
info you offer, "cutworm" is my best guess, too.

Well, that's new to me. But I'll go looking for cutworms, try the
collars. We had one plant so attacked last year, 6 this year.

Hornworms can leave the same kind of damage but it would likely be
more extensive than you describe and they're pretty easy to spot.

Yes.


Cutworms spend their days curled up snoozing just under the
surface, in the upper 3/4-inch...

I'll look there.
