Research Bulletin (Iowa Agriculture and Home Economics Experiment Station)


'rhe work presented in this bulletin attempts to open up this field of investigation and supply data bearing on the toxic action of formaldehyde and the influence thereon of concentration of the solution, of temperature of treatment and of duration of exposure. The data is limited to two organisms, Actinomyces scabies and Rhizocttpmoia solani, as they occur on the surfaces of potato tubers. Both laboratory and field work were carried on, altho the latter was limited due to the time required to get results and the non-controlled external factors which influence such results.
