A Technical Report from The Bartlett Tree Research Laboratories

Black root rot is the common name of a root disease caused by the fungi Berkeleyomyces basicola and B. rouxiae (formerly Thielaviopsis basicola) which can infect many woody and herbaceous plant species worldwide [1]. The fungi infect fine roots and cause black lesions which expand and eventually girdle and kill the roots. Advanced infections lead to decline in many hosts and mortality in highly susceptible species.
