    A survey was conducted in the Coweeta Basin, Macon County, North Carolina, to determine the incidence of root diseases and their relatedness to ozone symptomatology in two eastern white pine (Pinus strobes) plantations. Heterobasidion annosum was isolated from < l% of root segments sampled in a stand without symptoms of ozone-caused foliar injury. No root pathogens were found in a stand with symptoms of ozone-caused foliar injury. No relation was found between injury caused by ozone and the incidence of root diseases in these stands.
