I have bugs eating the tops of my radish plants. Do they need the tops to grow and an organic solution?

There are several kinds of pests, including caterpillars, that feed on the tops. Without seeing the bug, I cannot ID it. But, the standard organic treatment for most pests is neem oil and may work on caterpillars too. In addition, Bacillus thuringiensis, also known as Bt, effective for caterpillars. As long as the bulb and roots are still intact and healthy, the radish will continue to grow.
