^{z}Among trees inoculated with*Raffaelea*spp., the proportion of trees with greater than one-third crown wilt symptoms significantly differed between the propiconazole group and the untreated group after 9 weeks (χ^{2}= 10.77,*P*= 0.001) and 12.5 or more weeks (χ^{2}= 16.36,*P*= 0.0001).↵

^{y}Among trees inoculated with*Raffaelea*spp., the proportion of trees from which*Raffaelea*spp. was reisolated significantly differed between the propiconazole group and the untreated group (χ^{2}= 13.33,*P*= 0.0003).
