species have historically been delimited by their morphology, cytology and biochemistry [3, 4, 5].
In 2011, we isolated and characterized a population of newly occurring strains of Phytophthora
from tomato and potato hosts growing in heavily blighted fields in several locations in the United States.
After the baiting, culturing, and identification of Phytophthora
In the case of Phytophthora
blight, the parasite is transferred through water.
Meanwhile, plant physiologists with the Agricultural Research Service say extracts from tree heartwood can limit the growth of Phytophthora
The disease - known as Phytophthora

This is one of the reasons azaleas are planted in peat moss; the low pH of the moss discourages growth of the phytophthora
fungi that regularly decimate azaleas wherever soil pH is high, as in most of southern California.

Cases of the phytophthora
ramorum disease -known as sudden oak death disease because it has struck 80% of tan oaks in the western United States -have appeared in Cornwall.
Sudden Oak Death - Latin name phytophthora
ramorum - has already killed tens of thousands of trees in the US since it was first detected in 1995.
In California, several species of trees are infected with Phytophthora
, a fungus related to the one responsible for the Irish potato famine (Davidson et al.
