[The influence of choramphenicol and streptomycinsulphate on the growth of Pectobacterium carotovorum var. atrosepticum (van Hall) Dowson (author's transl)].

Abstract

The influence of the antibiotics chloraphenicol (D-threo-form) and streptomycin sulphate against Pectobacterium carotovorum var. atrosepticum (syn. Erwinia carotovora) was investigated in vitro and on potato tubers. Chloramphenicol showed a greater effect as streptomycinsulphate in the applied concentrations. The success of the control of soft rot is determined by the period between the inoculation and the treatment of the tubers. 6 several strains of P. carotovorum var. atrosepticum showed a different sensibility to chloramphenicol and streptomycinsulphate.
