In the first assay, SS doses of 0, 2.5, 5.0, 7.5, and 10% were used. For the second assay, SS doses were 0, 0.5, 1.0, 1.5, 2.0, and 2.5%, incorporated in soil, with previously corrected pH and added with chemical fertilizers at the rate recommen-ded for the crop. Plants that had not been inoculated with the pathogen were maintained in both assays. No efficacy was verified for the different SS doses studied in the assays on the reduction of disease severity symptoms, as well as on dry mass of inoculated plants. Concentrations of SS incorporated to the substrate higher than 5% were toxic to bean plants, reducing dry mass of plants.
