Phytophthora (from the Greek word for “plant destroyer”) is a genus of fungus-like microorganisms belonging to the class oomycetes. Species of this genus infect a lot of different plant species. The symptoms are not always clear and the choice of countermeasures depends on the identification of the pathogen.

• In fruit production, Phytophtora cactorum amongst other things causes crown rot.
• Phytophthora ramorum infects a lot of wood species. These include species of Viburnum and rhododendrons in tree nurseries and gardens. 
• Phytophthora infestans is the causative pathogen of late blight in potatoes and brown rot in tomatoes.
