Phytophthora root rot

Phytophthora root rot (Phytophthora spp.) are usually associated with root rots of established plants but are also involved in damping-off.

These species enter the root tips and cause a water-soaked brown to black rot similar to Pythium. These fungi survive indefinitely in soil and plant debris.
