Control of Phytophthora Root Rot in Fraser Fir Christmas Trees BROKEN

Phytophthora root rot is the only serious disease of Fraser fir Christmas trees in western North Carolina. It is caused by a fungus that inhabits the soil and infects many woody plants through the roots. It can lie dormant in the soil for several years waiting for a susceptible host such as Fraser fir and the right environmental conditions, including warm soil temperatures (above 54 degrees F.) and soils saturated with water to infect plant roots.
