Turnip and Radish Leaf Problem
I have planted turnips and radish from seed. The leaves of both are like lace, with small holes throughout the leaves. Can you tell me what the problem is and how to treat it?

There are several kinds of caterpillars that causes that kind of damage. Without seeing the bug, I cannot ID it. But, the standard treatment for almost any caterpillars is Bacillus thuringiensis, also known as Bt. You can also try neem oil. This is usually effective on those kinds of pests.
