Leaves were sprayed with fungicides at recommended doses (full) and 1:10 dilutions and then inoculated with six MR strains (MR-N5, MR-N10, MR-N11, MR-S3, MR-S4, MR-S7) or five sensitive strains (S-N8, S-N9, S-N11, S-S4, S-S10), each with two or three replications. Infections were rated as successful when expanding lesions were observed after 72 h. Standard deviations are shown in parentheses.
