Abstract: The concentration of CO2 in the atmosphere has been increasing significantly since the Industrial Revolution. Because of the potential impacts of the increase in CO2 from the air on the various pathosystems, assays were carried out in a controlled environment to check the effects of elevation of the concentration of CO2 from the air on Cylindrocladium candelabrum in detached leaves and seedlings of Eucalyptus urophylla. In three trials, detached leaves were wrapped in plastic trays with foam moistened with concentration of 607 ± 86, 705 ± 105, 855 ± 152 and 1101 ± 305 micromol mol-1 CO2 from the air, sprayed with conidia of the pathogen (2 × 105 conidia ml-1) and maintained at 28 ± 1.7 oC and photoperiod of 12 h for 21 days. It was evaluated the severity of leaf spot and the sporulation of the pathogen. In both experiments with seedlings of eucalyptus, the seedlings were grown in plastic tubes, kept in plastic boxes containing vermiculite at the bottom and kept in concentrations of 451 ± 35 (control), 645 ± 118, 904 ± 116, 1147 ± 216 micromol mol-1 CO2 per 30 days for acclimatization. After this period, the seedlings were sprayed with conidia of the pathogen and kept on the same conditions for six days. It was evaluated the incidence of lesioned leaves, leaf spot severity and the number of leaves containing spores of the pathogen. The height of the seedlings, the diameter of the stem and the weight of the dry matter of the aerial part and root were also evaluated. In the tests with detached leaves, the increase of CO2 concentration had no effect on the severity of leaf spot and sporulation of the pathogen. In seedlings, the elevation of CO2 concentration decreased the incidence of leaves lesioned, the severity of the disease and the number of leaves containing spores of the pathogen when compared to the control. In the variables of plant growth, the increase in the concentration of CO2 has ...
