Summary: This presentation will help consultants, growers, and other agricultural professionals in the soybean production regions of the United States to understand Fusarium spp. capable of causing soybean root disease. About 19 Fusarium spp. have been found associated with root rot of soybean. In general, Fusarium root rot can be difficult to diagnose because the causal agents may be primary or they may colonize roots along with other fungi. This presentation will specifically cover: symptoms caused by Fusarium on soybean root; how the Fusarium spp. vary in their aggressiveness; how few soybean genotypes vary in their resistance to multiple Fusarium spp.; cross-pathogenicity of common Fusarium spp. infecting soybean and corn and how Fusarium spp. interact with soybean cyst nematode under controlled conditions.
