    TBI = Treated before inoculation (days). All inoculations on same date. Lesion per leaf area = Percent Mean lesion area covered relative to the leaf area measured 10 days after inoculation. There was a single plant replicate and 5 subsampled leaves per replicate in each of 4 treatment blocks. Mean separation in columns with LSD, P ≤ 0.05, except for 28 days / Camellia. P ≤ 0.05. ANOVA on square root transformed data. Means in columns followed by unlike letters are significantly different.
