Abstract

The effect of seven disinfectants on Clavibacter michiganensis subsp. sepedonicus and Erwinia carotovora subsp. atroseptica was tested on metal, plastic and wood surfaces in laboratory trials. lobac P was the most effective disinfectant in the control of E. carotovora on clean and dirty surfaces. Ipasept and Menno-Ter-forte were effective on plastic surfaces, but dirt reduced their efficacy. The least effective preparations were Deskem-1, Virkon S and Korsolin. lobac P, Korsolin and Virkon S were the most effective disinfectants against C. michiganensis. The efficacy of Ipasept and Menno-Ter-forte was reduced by dirt. The least effective preparation was Deskem-1.
