Efficiency of strain Lu10-1 introduced before or after inoculation with C. dematium in controlling mulberry anthracnose in a greenhouse. (a) Lu10-1 applied to the leaves inoculated with C. dematium. (b) Lu10-1 applied to uninoculated leaves. (c) Lu10-1 applied by drenching the soil. Grey columns indicate treatment with Lu10-1 strains and white columns indicate treatment with LB medium (as control). Data are the average of four experiments for three test spots and analyzed using Student's t-test (P ≤ 0.05). Error bars represent SD. The lowercase letters indicate values, with 'a' being the highest, and 'h' the lowest value. The same letters within a column mean that no significant differences exist between the numbers.
