Answer
I would venture a guess that it is either aphids, mites, or flea beetles attacking the plants.  You can control any of these insects with insectidal soap, which can be purchased at most garden centers. You can also spray them with either rotenone or pyrethrum. Both of these products are organic, meaning they're non-toxic to humans, pets, and the environment. They are made from plant derivatives, and break down in the soil with no residual effects. They are extremely effective against each of the insects I have described.

Attached is a link to two companies that market both products.
