Conteúdo: 	The objective of this work was to evaluate the effects of increased air&#8209;CO2 concentration on plant growth and on leaf&#8209;spot caused by Cylindrocladium candelabrum in Eucalyptus urophylla. Seedlings were cultivated for 30 days at 451, 645, 904, and 1,147 &#956;mol mol&#8209;1 CO2; then, they were inoculated with the pathogen and kept under the same conditions for seven days. Increased CO2 concentration increased plant height and shoot dry matter mass, and decreased disease incidence and severity. Stem diameter was not affected by the treatments. Increased concentrations of atmospheric CO2 favorably affect eucalypt growth and reduce leaf&#8209;spot severity.
