Project Summary

This project has previously identified the Pythium species that are present in a representative sample of soils from Minnesota soybean growing areas and determined their occurrence and prevalence. The Pythium isolates will be evaluated for their pathogenicity on selected Public and Private soybean cultivars considered either resistant or susceptible and on corn because the role of corn as a rotational crop with soybeans. Because current management recommendations emphasize the use of fungicidal seed treatments for limiting stand loss and damping-off and because of reports of decreasing sensitivity to seed treatment fungicides, the isolates will be tested for their sensitivity to seed treatments, mefanoxam, trifloxystrobin, azoxystrobin, and selected additional recommended seed treatments.

Project Objectives

1. Determine the pathogenicity of the 32 Pythium species on soybeans and corn.
2. Determine the sensitivity of isolates of the 32 Pythium species to metalaxyl, trifoloxystrobin, and azoxystrobin.

Project Deliverables

1. Knowledge of the pathogenicity of Pythium species on soybeans and corn.
2. Knowledge of the sensitivity of Pythium isolates to metalaxyl, trifoloxystrobin, and azoxystrobin.
