Interactions of SCN with brown stem rot of soybean

Iowa fields are commonly infested with both SCN and brown stem rot (BSR). In the early 1990s, researchers observed that BSR-resistant soybean varieties had much greater than expected levels of BSR disease in fields infested with SCN than in those without SCN.

Research was initiated in the mid 1990s to study how SCN affects the fungus that causes BSR (Phialophora gregata, now sometimes called Cadophora gregata) and how the nematode affects BSR disease symptom development, infection and colonization by the BSR fungus, and soybean yield.
