The subject of apple rust in this state has assumed considerable importance during the past season so that a treatment of the species of apple rust in Iowa will not be out of place.
A few years ago the writer of this bulletin prepared for the Division of Vegetable Physiology and Pathology, a paper on these rusts as affecting forest trees of the west. With the consent of Dr. Albert F. Woods, Chief of the Division, I present that portion of the above paper which deals with the apple rusts. I wish especially to express my thanks to Mrs, Patterson and the Division for the loan of material and for other assistance in the preparation of this paper.
