Title: Influence of Infection Court, Host Vigor, and Culture Filtrates on Canker Production by Botryodiplodia Theobromae Conidia in Sycamore

Author: Lewis, R. Jr.;

Date: 1978

Source: Plant Disease Reporter 62(11):934-937

Publication Series: Scientific Journal (JRNL)

Description: Some of the factors that influence canker development in American sycamores inoculated with Botryodiplodia theobromae conidia were determined. A combination of B. theobromae culture filtrates and conidia resulted in 100% canker production when introduced into stem wounds; however, a combination of Cephalosporium diospyri culture filtrates and B. theobromae conidia resulted in no canker production in healthy sycamores. Inoculations with conidia without fungous filtrates resulted in canker development at wounds 0.5 cm below pruned twig terminals but not at wounds on branches with intact terminals. Conidial inocula also induced canker development in Cephalosporium-wilted and water-stressed sycamores. Cankers resulting from conidial inoculations are favored by stress in American sycamores.
