On one of my rose bushes I started to see a white scaly growth on the stems.

I've cut back the stems but it's still coming back. Is there a treatment for it.

Answer: The white scaly growth on your rose stems sounds like rose scale. This pest is best controlled with Lime Sulphur during winter when the rose is dormant. Now that the bush is covered in foliage there is no product that will curb the scale without harming the leaves and flowers. Removing this scaly growth with a soft toothbrush and some soapy water is the only method we can recommend. It may seem tedious and time consuming but at least it beats doing nothing.
