The disease incidence in field plot

The disease incidence in field plots treated with two B. amyloliquefaciens QL-18
formulations (RCC18 and peat18). RCC18 and peat18 refer to the mixtures of
B. amyloliquefaciens QL-18 with RCC and peat2, respectively. The disease incidence was
evaluated at the time of harvest. Tomato plants treated with RCC18 at both the seedling
and transplanting stages (RCC18 þ RCC18 treatment) showed the lowest disease
incidence (P < 0.001). Different letters indicate significant differences (HolmeSidak
method; P < 0.05) among the treatments.
