Trichoderma anti-fungal activity

This method of plotting ionic data was developed in Oxford by Simon (1950), who found that the majority of those substances that are most active when least ionized nevertheless have ions which exert some of the activity. For another example, the anti-fungal action of 2,4-dinitrophenol (p. Ta 4.0), at various pH values, on the fungus Trichoderma viride, see Simon and Beevers (1952).
