Seed Treatment with Calcium Carbonate Containing Bacillus amyloliquefaciens PMB05 Powder Is an Efficient Way to Control Black Rot Disease of Cabbage

Black rot disease is a serious bacterial that harms vegetable crops of the Brassica genus (especially cabbage plants) worldwide. The causal agent, Xanthomonas campestris pv. (Xcc), seed-borne pathogen primarily infects seedlings. Previous studies suggest strain, Bacillus amyloliquefaciens PMB05, can intensify plant immune responses against black and reduce occurrence. In immunity, several reactions occur during attack, but elevation calcium ion concentration in cells essential induction defense responses. Therefore, this study aims to investigate whether control plants be improved by integrating carbonate formulation for preparing B. PMB05. Firstly, we found addition revealed have significantly increased cell endospore populations PMB05 fermentation liquids. To increase convenience field, these liquids were converted powder form subsequent analysis. Results grown seedlings from seeds, mixed with powders, intensified control. We further compared distinct seed treatments using one evaluate its feasibility field application. results demonstrated efficacy yield treatment (SD-160C2) 56.46% 5.91%, respectively, at 10 weeks post transplanting. Interestingly, combined calcium-containing commercial fertilizer spraying did not disease, it weight cabbages after harvest. concluded carbonate-containing an efficient way cabbage.
