Plant growth and leaf-spot severity on eucalypt at different CO2concentrations in the air 86
Silva,Carlos Eduardo Oliveira da; Ghini,Raquel.
The objective of this work was to evaluate the effects of increased air-CO2 concentration on plant growth and on leaf-spot caused by Cylindrocladium candelabrumin Eucalyptus urophylla. 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 CO2concentration 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.

Promotion of growth and control of damping-off (Rhizoctonia solani) of greenhouse tomatoes amended with vermicompost 85
Rivera,MC; Wright,ER; López,MV; Garda,D; Barragué,MY.
The pathogen Rhizoctonia solani (teleomorph Tanatephorus cucumeris) can affect tomatoes germination and emergence and cause basal rot of seedlings. It is generally accepted that composts suppress plant diseases, improve soil nutrient availability and stimulate plant growth. However, no reports have been found on the simultaneous evaluation of vermicompost as plant growth promoter and suppressive to damping-off caused by R. solani on tomatoes. This research evaluated the suppressive effects of different concentrations of vermicompost against R. solani and the ability of vermicompost to promote tomato seedlings growth. The microbial composition of the substratum was explored. Thirty six microorganisms were isolated, 13 of which were antagonic to R.solani in...
