Control of Phytophthora Root Rot in Field Plantings of Fraser Fir with Fosetyl-Al and Mefenoxam

D. M. Benson, J. R. Sidebottom, and J. Moody

March 2006

Research

Fungicides were evaluated for control of Phytophthora root rot for five growing seasons in two field plantings of Fraser fir affected by Phytophthora cinnamomi in western North Carolina. Apparently, at least under conditions not overly conducive to the disease, the fungicide treatment programs can delay the onset of high mortality rates caused by P. cinnamomi in Fraser fir for up to three growing seasons.
