Conteúdo: | This study developed fast and rediable method of inoculating Brachiaria, a genus of tropical forage grasses, with Rhizoctonia solani, the causal agent  of foliar blight disease. Using this method, 42 brachiaria accessions were inoculated in both field and glasshouse, and their  reactions to R. solani evaluated. Severity of infection in the glasshouse was rated by percentage of infected and  numbers on infected plant issue correlated positively with percentage of infected leaves (r = 0.72). These percentages also correalted positively with each other (r =0,77). Three accessions of B. humidicola (CIAT 16868, 16886 and 6369) and the B. dictyoneura accession CIAT 6133 (cv. Llanero) had consistently moderate levels of resistance. All other accessions of B.brizantha were susceptible.
