|Contribution||Reported that bunt or smut of wheat was caused by microscopic "spores" of fungi.|
|Notes||Also that it could be prevented by soaking wheat seeds in copper sulfate. This could be regarded as the first record of the pathogenicity of a micro-organism (and of a disease being controlled by willful use of a chemical to destroy the pathogen). See 1885. Ainsworth gives further details of this work by Isaac-Benedict Prevost; notes that obscurity of publication caused delay in impact, but cited by others in 1847.|
