Abstract
The effect of tap water, soil extract and potato dextrose agars and a range of different water potentials on the growth and interactions of the pathogens Sclerotinia sclerotiorum, Botrytis cinerea and Rhizoctonia solani, and the antagonists Coniothyrium minitans and Gliocladium roseum were investigated. Different media had significant effects on growth rates of all fungi, but PDA, the medium richest in available carbon, did not always give the maximum growth rate for all fungi. Growth rates gradually declined for most fungi with decreasing water potential but the rate of decline was different for each fungus and was dependent upon both medium and osmoticum used. Colony morphology and pathogen‐antagonist interaction also changed with decreasing water potential and media. Production of volatile and non‐volatile antibiotics was also dependent upon the media used. The relevance of these results to screening methods is discussed.
