Regulated Hosts and Associated Plants (HAP)

The U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS) maintains a list (PDF, 92K) of regulated Phytophthora ramorum hosts and associated plants (HAP). More than 100 plant species are currently on this list. As new hosts for the disease are found, they are added to this list and are then subject to regulation.
