Studies were conducted o­n the in vitro effects of 27 salt compounds and seven commercially available fungicides o­n mycelial growth of Alternaria alternata, Botrytis cinerea, Fusarium avaneceum, Phytophthora erythroseptica, Phytophthora infestans, Verticillium albo-atrum and V. dahliae at Agriculture and Agri-FoodCanada in Charlottetown, Prince Edward Island. Growth media were amended with each compound at three concentrations--0.002 M, 0.02 M, 0.2 M plus an appropriate control.

Several salt compounds were tested in vitro as growth inhibitors of Erwinia carotovora spp. atroseptica strains 3, 6, 31, 196, 198 and Erwinia carotovora spp. carotovora (Ecc) strains 23, 24, 59, 61, 71. Studies examining the preventative and curative effects of the most effective compounds were conducted using Ecc 71 as the test pathogen.

The preventative and curative effects, as well as seed piece phytotoxicity of various salt compounds were tested for their ability to inhibit infection by late blight and pink rot pathogens of potato. Compounds were applied as dips at the concentrations 0.002 M, 0.02 M, 0.2 M respectively. Tubers were inoculated with sporangia of P. infestans or active zoospores of P. erythroseptica .
