little black bugs on bok choy

We have little black bugs (<= 2mm across) on the bok choy in our garden. The plants are growing well, but the bugs eat little holes in the margins of the leaves. The lettuce and beans on either side of the bok choy are untouched. Is there a way to get rid of these without pesticides?

 

Hello,

It is flea beetle that is attacking your plants. Here is a link which describes organic methods of control. Good luck.
