    Description

    Two strains of Botryodiplodia the obromae were isolated from cankered sycamore trees; one was virulent and the other was less virulent. The less virulent strain colonized all sycamores inoculated with it but, in most cases, did not induce cankers unless the sycamores were wilting from Cephalosporium diospyri infections. The virulent strain of B. theobromae induced cankers in both wilting and non-wilting sycamores but it induced cankers more rapidly in the wilting trees. Cephalosporium wilt can make sycamores more vulnerable to Botryodiplodia cankers.
