Seedlings were cultivated for 30 days at 451, 645, 904, and 1,147 μmol mol‑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‑spot severity.  aCarbon dioxide  aDisease incidence  aClima  aCrescimento  aDióxido de carbono  aEucalyptus Urophylla  aMancha foliar  aMudança Climática  aBeneficial effects  aClimatic change  aCylindrocladium candelabrum  aEfeito benéfico  aIncidência de doença  aLeaf spotting  aPlant growth performance1 aGHINI, R.  tPesquisa Agropecuária Brasileira, Brasília, DFgv. 49, n. 3, p. 232-235, mar. 2014.
