In planta screening of promising endophytes from the leaf disk bioassay for antagonism against cucumber powdery mildew using a detached whole leaf bioassay. (A–D) Representative pictures of: (A) chemical fungicide positive control (Prothioconazole), (B) commercial biocontrol agent positive control (Bacillus subtilis strain QST 713), (C) example of a typical promising endophytic bacteria; Pantoea EKM103V, (D) and the negative control (LB broth amended with filter sterilized 0.01% Tween 20). (E) List of tested endophytic bacterial strains, their respective plant seed source, corresponding disease index, preventive effect values and visual score p-values (calculated using independent samples t-test, one-tailed and unequal variance). The rows highlighted in gray denote promising strains that significantly (p < 0.1) suppressed the disease in comparison to the negative controls. A greater Disease Index indicates increased disease symptoms, whereas a greater Preventative Effect denotes improved control of the disease. The circumflex accent (ˆ) denotes that fresh fruits were used as the seed source.
