Project Summary

From 1997-2008, the estimated reduction of soybean yields in Kansas have averaged 2.7 million bu/yr for seedling blights, 6.2 million bu/yr for charcoal rot, and more than 2.4 million bu/yr for other root diseases (including SCN, SDS, Phytophthora and Fusarium root rots).

Project Objectives

1. Determine the identity of soil- and seedborne Fusarium spp. of soybeans in Kansas.
2. Evaluate the pathogenicity of soil- and seedborne Fusarium spp. upon commonly grown soybean varieties.
3. Determine sensitivity and resistance of Fusarium pathogens to biologicals and compare with commercial seed treatment fungicides.
4. Examine the interactions between seedling (Fusarium, Pythium ultimum, and Rhizoctonia solani) and root pathogens (Macrophomina phaseolina, Fusarium virguiliforme, and Heterodera glycines).
