Phytophthora (from Greek φυτόν (phytón), "plant" and φθορά (phthorá), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species cause economic losses on crops worldwide, as well as environmental damage in natural ecosystems. Phytophthora species resemble fungi but are not. While they are most closely related to aquatic organisms, such as brown algae and diatoms, they can also exist on land.
Understanding the Context
However, Phytophthora organisms are often referred to as water molds because they do need water to complete their life cycle. Phytophthora are microbes that harm plants (plant pathogens). They are considered “water molds” and they are more closely related to brown algae than fungi. Phytophthora are often spread via the movement of infected plants and contaminated soil.

Key Insights
Many members of the Oomycota genus Phytophthora cause economic and environmental impact diseases in nurseries, horticulture, forest, and natural ecosystems and many are of regulatory concern around the world. At present, there are 223 described ... Phytophthora is a word used to describe more than just a single disease. The term refers to many different plant pathologies which have more or less severe impacts (crown rot, mildew, ink disease, etc.) Phytophthora as a genus is extremely plastic in terms of genetic and phenotypic variability, pathogenicity, host range, and long-term survival strategies. As exotic pathogens they are devastating in forest and other plant ecosystems as has been observed in Australia, Oregon, Europe, and elsewhere.

Phytophthora (pronounced Fy-TOFF-thor-uh) is a genus of microorganisms in the Stramenopile kingdom which includes water molds, diatoms and brown algae. Phytophthora species resemble true fungi because they grow by means of fine filaments, called hyphae, and produce spores.
