The very wet and warm planting conditions across much of Iowa have been ideal for the development of Phytophthora damping off. Plants infected by Phytophthora have a brown discoloration extending from the root up the stem (see photo). Alison Robertson's lab is continuing to assess the diversity of Phytophthora in Iowa and requests your help in this project. The lab would like to obtain plant samples from suspected Phytophthora-infected plants as you find them.
