DescriptionIn the Mississippi Delta, Botryodiplodia theobromae placed beneath the bark of sycamore trees incited cankers on 99% of trees inoculated in July, and on 66% of those inoculated in September. Infection occurred following inoculations made throughout the year, but was most common when the fungus was introduced during warm weather. The quality of the site for sycamore growth did not significantly influence disease development. Eighty-four percent of trees inoculated on good sites, and 95% of those on poor sites, developed cankers. The fungus caused no cankers unless it was placed beneath the bark. Ninety per cent of the inoculated wounds formed enlarged cankers. Insects probably spread the fungus to noninfected trees.
