All bacterial broth and metabolite treatments suppressed the development of lesions caused by P. cactorum on detached pecan leaves at 4 d (F = 10.49; df = 8, 123; P < 0.0001) and 7 d (F = 9.47; df = 8, 124; P < 0.0001) post-inoculation (Fig. 2).
At 4-d-post-inoculation, no differences among metabolite or bacterial broth treatments were detected except the X. bovienii metabolite treatment (25%) resulted in smaller lesions and thus greater suppression compared with the P. luminescens broth (Fig 2).
At 7-d-post-inoculation, no difference among metabolite or bacterial broth treatments were detected and all treatments were different from controls (which were statistically similar to each other) (Fig. 2).
