Biological control of Pectobacterium carotovorum subsp. carotovorum, the causal agent of bacterial soft rot in vegetables, in vitro and in vivo tests

Abstract Background Several chemical bactericides were applied for controlling soft rot bacteria, Pectobacterium carotovorum subsp. , which causes the destructive disease to many economically important vegetables, but because of their toxic hazards on human and environment became limit. The biocontrol was control plant pathogens. Therefore, this work is aimed study antagonistic activity bacterial agents, i.e . Bacillus subtilis pumilus megaterium Pseudomonas fluorescens fugal Trichoderma harzianum viride virens under in vitro vivo tests. Results tested treatments could protect potato tubers against development rot. T. highly effective reducing symptoms inoculated tuber slices, when at same time or 2 h before pathogen inoculation, while B. after inoculation. In whole technique, B.pumilus protected stored artificially infection conditions, than P. respectively. Conclusion Application fungal agents specify species can play an role vegetables increase periods storage conditions without any effects.
