This was the first year the station pathologist walked the nursery looking at each accession with the purpose of noting seed transmissible maize diseases and exotic diseases not known to occur in Iowa. Pathology notes were not extensive, but no exotic diseases were noted. Specific notes on Stewart's wilt and Goss's wilt were obtained. None of the exotic downy mildews were observed. The nursery was not examined for possible virus infected plants
