Caterpillar eating trophy radish

[Gilly]

Trying to grow trophy radish in a pot on my back deck and I have had these caterpillars munching on them the last couple days. Anyone know what they are or how to keep them from eating the leaves? I am guessing it is some sort of moth larvae since they have been thick out the back door lately letting the dogs out.

I can't get your picture to come up. But is it a Army worm?

Its showing it for me, Sorry about that. Its black with a white stripe down its back with an orangish head. It doesnt look like an army worm from the pictures Im seeing online.

Doesn't look like a cabbage worm either. I had a problem with caterpillars eating my brassicas a couple years ago so I did what I normally do with my cabbage and broccoli, I broke out the Dipel dust and lightly dusted the entire plot. Went back a couple of days later and no more CATS. Saved the brassicas from being wiped out.

Liquid sevin will kill just about anything.
