Effect of Inoculation Sequence and Humidity on Infection of Puccinia recondita by the Mycoparasite Darluca filum. D. P. Swendsrud, Former Research Assistant, Department of Plant Pathology, University of Minnesota, St. Paul 55101; L. Calpouzos, Professor, Department of Plant Pathology, University of Minnesota, St. Paul 55101, Present address: Department of Plant Sciences, University of Idaho, Moscow 83843. Phytopathology 62:931-932. DOI: 10.1094/Phyto-62-931.

The application of pycnidiospores of Darluca filum to wheat seedlings 3 days prior to inoculation with uredospores of Puccinia recondita resulted in (i) more severe rust infection and (ii) less uredial infection by the mycoparasite than when the two organisms were applied simultaneously, or when the rust fungus was applied first in the sequence.
