Disease incidence (DI, %) in Phaseolus vulgaris cv. Quivicán seedlings treated with biological or chemical compounds and inoculated with Rhizoctonia solani isolate CCIBP-Rh1 at 28 days growing on non-sterilized or sterilized soil. Each column represents the mean of 40 seedlings per soil and treatment combination; and columns with a common uppercase or lowercase letter do not differ significantly according to Zar’s multiple comparisons for proportions test (p = 0.05) for treatments on non-sterilized or sterilized soil, respectively.
