Seedling diseases are caused by oomycetes, namely Pythium spp. and Phytophthora sojae, and fungi (Fusarium ssp. and Rhizoctonia solani). With the exception of P. sojae, there is limited information on the biology and epidemiology of many of the pathogens associated with seedling diseases. The goal of this project is to improve our understanding of the biology and epidemiology of Pythium ssp. causing seedling disease.

1. Characterize the biology of Pythium spp. that causes seedling disease.
2. Determine the optimum conditions for infection of and disease development in soybean seedlings by Pythium spp.
3. Assess the sensitivity of Pythium spp. to seed treatment fungicides.
4. Improve farmer and industry knowledge of seedling pathogen biology and epidemiology.

1. Improved knowledge of the biology of Pythium spp. that causes seedling disease.
2. Information on the sensitivity of Pythium spp. to seed treatment fungicides.
3. Provide useful information to farmers and industry on seedling pathogen biology and epidemiology.
