Answer: Based on your description I think you may be seeing scale insects on your tree. These can be treated using a dormant oil spray during the winter. However, since I have not seen the tree, I would also suggest you consult with your local county extension to obtain a specific identification of the pest. Based on knowing that, they can recommend what to use to treat it and how/when is best to apply it for maximum results. Good luck with your peach tree!
