Characterization of Pythium spp. from Three Ohio Fields for Pathogenicity on Corn and Soybean and Metalaxyl Sensitivity

A. E. Dorrance, S. A. Berry, P. Bowen, and P. E. Lipps

February 2004


Pythium spp. were baited with corn and soybean seed from soils collected from locations in Ohio where soybean and corn stand establishment was a concern. Five species were recovered and tested for pathogenicity on corn and soybean seed and sensitivity to the seed treatment fungicide metalaxyl. There was a range of both pathogenicity and sensitivity to metalaxyl within and among the Pythium spp. recovered.
