Control of bacterial soft rot disease of potato caused by Pectobacterium carotovorum subsp. carotovorum using different nanoparticles

Abstract

The aim of the study was to control potato soft rot bacterium, Pectobacterium carotovorum subsp. carotovorum using three different synthetic nanoparticles “silver, chromium III oxide and zinc oxide” within two levels in vitro and in vivo. All three nanoparticles exhibited considerable inhibitory activities more than chloramphenicol as antibiotic. Silver NPs was the most effective within highest inhibition zone at the lowest MIC (10.75 mm/50 ppm) followed by chromium III oxide NPs and zinc oxide NPs (10.28 mm/100 ppm and 10.08 mm/150 ppm), respectively. Meanwhile, chloramphenicol was categorized on the last (9.34 mm/150 ppm). In vivo, controlled bacterial soft rot disease of potato was performed with Ag NPs, Cr₂O₃ NPs and ZnO NPs within MBC (1800, 2200 and 2600 ppm, respectively) in storage and greenhouse experiments.
