Information for Nursery Professionals
Phytophthora can cause substantial problems for nurseries because they are challenging to manage and some species are heavily regulated. Therefore, the aim of this webpage is to provide information and resources to help you keep Phytophthora ramorum and other diseases out of your nursery.
Here you will find information about Best Management Practices and resources produced specifically for managing plant pathogens in nurseries. Note that many of these practices can be applied to control or prevent the establishment of a variety of plant pathogens.
